The key of how passive house performs lays on well designed ventilating which can not only filtrating too much moisture in the air and peculiar smell but pollen and dust, providing clean and fresh air for rooms. If you open the window for ventilation, a lot of quantity of heat will be lost, and the loss is more than the total quantity of heat that a passive house needs. Under most climate conditions, passive house wants certain heating but the quantities are small, which can be realized by ventilating. Through heating coil to warm up fresh air, the heating needs left can be met, and that is the concept of the fresh air system of passive house for supplying heating.

Principle of the ventilation of passive house

The basic principle of the ventilation of passive house: the muddy air in kitchen and bathroom is extracted (air exhaust) and the fresh air will be delivered in to where people live (air supply), and automatic air exhaust can be realized in hallway. For example, the standard of fresh air is 20m2/h for one person and per capital living space is 30m so that the quantity of air supply should be 1m/2(m?h). the highest temperature is limited as 50 ℃ and the corresponding heat load is 10W/m* in order to avoid the peculiar smell produced by excessive temperature causing the dust to be burned, meeting the requirement of heat supply.

The functions of ventilating

Ventilating, able to recycle the heat efficiently, emphasizes its own main functions: it can change the indoor air,  which can control the air humidity in case of mildewing; it can stop the accumulation of pollutants and it can remove the peculiar smell. In addition, there are additional functions: it can regulate the indoor air and clean the air ( acts as filter) to eliminate PM2.5; it can work as humidifying and dehumidification. Passive house applies the ventilating recycling the heat efficiently, lowering the heat loss, increasing the temperature of fresh air and enhancing the degree of comfort indoors. Meanwhile, the ventilating of passive house regulates the humidity indoors ( the optimal range is with relative humidity of 35%-55%), over or lower will do harm to health, especially the skin and respiratory system. If the temperature is too high, it will go mouldy; if the the temperature of internal surface is lower than 12.6℃, it will be liable to mildew; instead,  the temperature of internal surface is lower than 9.6℃, condensation will happen. Too low temperature will possibly damage the floor or musical instrument.

Thenow will strive to offer you hrv dehumidifier with good quality.

Here offer pieces of Information On Chemical Composition Of Silica Gel.

Silica gel alias: Silicic acid gel. It is a highly active adsorbent material and an amorphous material. The main component of silica gel is silica, which is chemically stable and does not burn. It has an open porous structure with strong adsorption and can absorb a variety of materials. When dilute sulfuric acid (or hydrochloric acid) is added to the aqueous solution of water glass, it will become hydrous silicic acid gel and become solid. The dissolved electrolyte Na+ and SO4 2-(Cl-) ions are removed by water washing. Silica gel can be obtained after drying.

Generally speaking, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.

Inorganic silica gel is a kind of highly active adsorption material, which is usually prepared by the reaction of sodium silicate and sulfuric acid and a series of post-treatment processes such as aging and submerge in acid. Silica gel is an amorphous substance. Its chemical formula is mSiO2. nH2O. It is insoluble in water and any solvent, non-toxic, odorless, stable in chemical properties, and does not react with any substances except strong alkali and hydrofluoric acid. Different types of silica gel have different micropore structure due to different manufacturing methods.

The chemical composition and physical structure of silica gel determine that it has many other characteristics which are difficult to be replaced by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. It is used by families as desiccant, humidity regulator, deodorant, etc., by industry as oil hydrocarbon decolorizing agent, catalyst carrier, variable pressure adsorbent, etc., and by fine chemical industry as separation purifier, beer stabilizer, paint thickener, toothpaste friction agent, polish remover, etc.

Organic silica gel is an organosilicon compound that contains Si-C bonds, and at least one organic base is directly connected to the silicon atom. Traditionally, those compounds that connect the organic base to the silicon atom via oxygen, sulfur, nitrogen, etc., are also considered as organosilicon compounds. Moulded silica gel is a little more complex with irregular shapes, including silica gel bowl, silica gel ice lattice, silica gel cake mold and so on.

After knowing information above,you may have a deeper understangding of silica gel composition and silica gel chemical formula.

Automated assembly refers to the assembly of products through the use of automated machinery or assembly robots and systems. Only a small part of the work is controlled by people. In most cases, automation is often used to produce a standardized product assembly line for a series of specific actions or activities. Automated assembly is an important part of many technology companies and medical research plants.

Today, automation components in many factories are used to create components and then assemble a variety of products, from the food industry to the electronics industry. Workers only need on-site supervision to ensure that the assembly line process can be maintained and their ability to produce thousands of high-quality products can be maximized in the shortest possible time.

Medical research facilities and food processing factories often use automated assembly processes in areas where human contact may lead to danger or product contamination. Manipulators or robotic equipment are used to deal with the sealed environment in the above product systems to minimize this risk.

Large manufacturing companies use larger automated assembly equipment, including large-scale products such as automobiles that use heavy robotic equipment. In these environments, except that only a few workers operate in the central control center, the other processes are to assemble vehicles independently using assembly systems. Although this form of manufacturing looks more like a replacement for manual work, it reduces casualties and human failures.

In recent years, with the prosperity of the domestic electronic industry, the industry of our automated assembly machine has also taken advantage of the rising trend. At the same time, many manufacturers are gradually carrying out automation reform, replacing manual labor with machines, so many enterprises are rushing to introduce automation equipment, but its main equipment is automated assembly machine.

Features of the automated assembly machine:

Lubricant is an indispensable additive in PVC processing. For lubricants, the commonly referred function in industry's can be summarized in two points, they are: it reduces the friction pre-melting particles of polyvinyl chloride and the macromolecules in the polyvinyl chloride melt. It is actually the most typical summary of the two aspects of lubricant action (internal and external lubrication). Then, we will discuss and analyze the internal and external lubrication of PVC lubricant from the technical level for you.

1.Internal lubrication

In terms of PVC, the internal lubrication of the lubricant and the plasticizer can be regarded as the same kind of material, playing the role of plasticizing or softening. The difference is that the polarity of the lubricant is lower and the carbon chain is longer. Therefore, compared with plasticizers, lubricants and PVC are less compatible. Lubricants are incompatibly (and moderately compatible) with polyvinyl chloride, so only a small number of lubricant molecules can pass through the chains of the polymer like plasticizers, weakening their mutual attraction. When the polymer is deformed, the chains can slip and rotate more easily without lowering the glass temperature of the polymer too much.

2.External lubricant

External lubrication refers to the interface lubrication mechanism. The lubricant is attached on the surface of the molten resin or on the surface of the processing machine or mold, forming a layer of lubricant molecules. lubrication interface which is formed by the existence of molecular layer of lubricant, reduced the friction between the resin and the processing machinery as as result. The viscosity of the sliding interface film and its lubrication efficiency depend on the melting point and processing temperature of the lubricant. In general, lubricants with long molecular carbon chains play a better role of lubrication because they keep the two friction surfaces away from each other.

3.What will happen if PVC lubricant is not used well?

"Small dosage, large effect" . This sentence is an appropriate description of PVC lubricant. The function of PVC lubricant is no less than stabilizer in the role of PVC processing. Generally, its use  needs to follow strict principles, such as slippery balance inside and outside, right amount moderate etc. If the degree of significance of PVC lubricant is not enough, and we do not follow principles that should be observed, what will happen if PVC lubricant is not used well?

A.Imbalance of internal and external lubrication.

Too much external lubrication. The extrusion speed is fast, the material is easy to produce, and the plasticization is not good. Too much internal lubrication. There will be large extrusion and poor plasticization of materials. Poor initial lubrication will make the extrusion torque larger. Insufficient lubrication in the later stage will lead to insufficient lubrication in screw homogenization section, compression section and die section, violent shear of materials, which will affect the surface quality and internal performance of extruded products. More seriously, it even causes decomposition.

B.Excess lubricant.

C.Excess lubricant is not always better.

Lubricant is incompatible with PVC resin. Too much lubricant will have a bad effect on PVC blending system. Lubrication of internal and external balance, is balance within a certain limit because the mixing system of lubricant and PVC has bad effect. In the actual production, there are many processing problems related to thermal stability and many defects of the products. The root cause may be the excessive amount of lubricant.

High melt point - melting point of paraffin wax in celsius is very suitable for making cylindrical candles, hand-dipped fine candles, moulded candles, moulded or carved gift candles. High melt wax is very hard and cannot retain its fragrance. Its melting point is 145 degrees Fahrenheit or 63 degrees Celsius. This kind of wax is needed to make all kinds of waxes mentioned above so that the candle will not sink itself when it is cooled. If this high melt wax is used to make candles, additives are needed.

Medium Melting Point - This kind of wax is usually used to make prayer candles and sometimes container candles. Its melting point is 127-145 degrees Fahrenheit or 53-63 degrees Celsius. This wax feels harder than low melting point wax, but it keeps its shape better. This wax has good fragrance retention, but additives are needed. This type of wax is massive and needs to be cut into small pieces to melt.

Low Melting Point - This type of wax melts at 127 degrees Fahrenheit or 53 degrees Celsius. Soft wax is an ideal material for making container candles and has the characteristics of lasting fragrance retention. Soft wax has strong flexibility and does not need additives until the candle burns out. Softer paraffin have many advantages, but they are difficult to process and emit more soot than other waxes.

Once you decide on the type of candle you want to make, you can choose the most suitable paraffin. Wherever you buy paraffin, you must know the melting point of the purchased paraffin, so that the gift candles will look good. When you buy, you need to have detailed instructions on the use of these waxes.

What is concrete mixer truck

Concrete mixer truck is a special truck used to transport concrete for construction; it is often referred to as a snail car because of its shape. A cylindrical mixer drum is mounted on this type of truck to carry the mixed concrete. The mixing drum is always rotated during transportation to ensure that the concrete being conveyed does not solidify. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space and making the volume of the mixing drum less and less.

Concrete mixer trucks structural principle

Structural principle of new concrete mixer truck: Concrete mixer truck consists of special equipment for automobile chassis and concrete mixing and transportation. The chassis of concrete mixer trucks produced in China mostly adopts the second-class universal chassis provided by the whole vehicle manufacturer. Its special mechanism mainly includes power take-off, front and rear brackets of the mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system and so on. 

Concrete mixer trucks woking principle

The working principle is that the power of the automobile chassis is taken out by the force taking device, and the variable pump of the hydraulic system is driven, the mechanical energy is converted into the hydraulic energy and transmitted to the quantitative motor, and the motor drives the speed reducer, and the stirring device drives the stirring device to carry out the concrete. Stir. Another type of mixer truck produced by Yantai Shenglida adopts a patent of the rotary seal, which can completely close the mixer drum and the inlet and outlet, and specifically solve the water evaporation and mortar stratification of traditional products. The series of problems such as dredging and driving safety has greatly improved the quality of concrete and building safety, and the effective volume of the mixing drum has increased to over 80%. The comprehensive performance of the whole vehicle has reached a new height. The fully enclosed mixer truck has Started to serve the Qingyan Weirong high-speed rail and high-quality construction projects.

The concrete mixer truck is used as a transportation vehicle. In terms of maintenance and repair, the maintenance and repair system of “regular inspection, mandatory maintenance, and condition-based repair” must be carried out in accordance with the regulations of the Ministry of Communications No. 13 of 1990. Under this premise, combined with the actual situation of the concrete mixer truck, maintenance and repair should be.

(1) Degreasing

Lipase enzymes used in leather industry has achieved good results in degreasing of crepe, fur, leather, gelatin, and the like. Candida lipolytica lipase can reduce the oil content of the raw material of the spinning material from 10% to 0.5%, to meet the spinning requirements, and does not affect the fiber strength. Lipase can also remove fat between leather collagen fibers and degrease for fur. It not only has the advantage of not affecting the thickness and fastness of the leather, it can also make the fur product full, soft and elastic. After lipase treatment, the small droplets in the gelatin solution can be removed, and the oil stains on the instrument rag and the optical components can be removed to improve the quality and cleanliness of the product.

(2) Preparation of chemical products and reagents

By utilizing the action properties of lipase hydrolysis, synthesis and trans-fatty acid, it is possible to prepare chemical products with high chemical production costs. Erucic acid and its derivatives have a wide range of chemical applications and can be used in petrochemical, textile, chemical, light, and plastic industries.

In recent years, due to the widening of the use of erucic acid and the increasing demand for erucic acid in the international market, the production of erucic acid has increased at home and abroad. At present, the production method of erucic acid is to hydrolyze canola oil and mustard oil under high temperature and high pressure, and then rectify to obtain a high purity product. Researchers have found that Candida lipolytica and Geotrichum can be used jointly on rapeseed oil to produce erucic acid, glycerin, saturated fatty acids, fatty alcohols and other products. The enzymatic production of erucic acid requires low action conditions and can result in high-purity product, which is a development direction of erucic acid production.

Description of Calcium aluminate cement

Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The product obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. This has the ability to harden very quickly: it forms a rigid solid within 24 hours.

Application of calcium aluminate cement

There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries.

 As binders, calcium aluminates are used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations.

 Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix.

 As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.

Calcium Aluminate Cement CA50 specification:

Calcium Aluminate Cement Construction method:

1. When preparing refractory concrete, fix on the aggregate according to using condition. Choose the proper capacity graduation to make maximum density. Be noted to match and adapt with cementing material.
2. According to certain proportion, add water and mix by man or machine into mortar and then begin casting construction. Use up the ready mortar within 40 min. Calcium Aluminate  Cement’s hydration heat concentrate on early stage. Casting thickness should not exceed 3 cm each time. Water curing immediately when concrete goes hardening and the curing time should not less than 3 days.
3. When prepare expanding cement, Calcium Aluminate clinker’s dosage is 73-76%, CaSO4·2H2O dosage is 24-27%. When prepare self-stressing cement, the mixing ratio of CaSO4·2H2O should be increased.

Calcium Aluminate Cement Notice:

1. In order to avoid uncontrollable setting time, do not mix with Portland cement, lime etc of which separate out calcium hydroxide cementing material. Before use, clean all the mixing machinery.
2. Steam curing to accelerate concrete’s hardening. The curing temperature should not higher than 50℃.
3. Refractory concrete’s late strength decline big, design should according to the lowest stable strength. CA-50 bonded concrete’s lowest stable strength should be determined by the lowest strength of 7-14 days of demoulding sample curing in 20℃±1℃ water.

Calcium aluminate Cement Packing:

by 50kgs bag. Store in shady, cool and dry place. Avoid stamp and mix with other substance.

Refractory Materials for Ceramic Kiln or Furnace Heat is transmitted via conduction, convection, radiation or a combination of them. Heat always goes from hot to cold. Without insulation, heat will be radiated into the atmosphere. <a href=”http://www.csacement.com/application/ceramic-kiln.html”>Kiln insulation bricks </a> can well solve the problem. Refractories are non-metallic insulation materials that retain their strength at high-temperature. Firebrick and ceramic fibers are the most common used refractory materials for high-temperature furnaces and kilns such as ceramic tunnel kiln. Refractories are mostly "dictated" by application parameters such as thermal process temperature profile and atmosphere. Oxides of alumina and silica are very common, while Zirconia, carbon and silicon carbide refractories are used for special applications. Thermal conductivity “k” is expressed in how many BTU's of heat will travel through one square foot of material of one-inch thickness in one hour. Every material has its own value. Insulation is the reciprocal of thermal conductivity. It is not necessarily the case that thicker walled kilns and furnaces are more efficient. The walls of the kiln absorb heat, and if the firing is not of excessive duration, it is completed before the walls of the kiln have become heated to capacity. In this case, thicker walls serve no purpose and only slow cooling. But for extended firing (like in continuous furnaces), thick walls may be desirable. Insulating bricks serve to increase the heat retention properties of the kiln. The air trapped inside the firebrick is a fantastic insulator because of its thermal conductivity of 0.16 versus bricks which have 2.13 – 3.7 depending on mean temperature. Trapping the air in small chambers, like in foam, provides good insulation. Convection is the most important mechanism of heat transfer in the lower temperature ranges. Once the heated surface become incandescent, these areas give off heat by radiation. It is therefore important that the insulation has a white and smooth surface because they radiate more efficiently.

We will explain to you about why are enzymes used in detergents below.

Alkaline lipase: Alkaline lipase is a new enzyme in detergent industry. Its main use is as new enzymes used in detergents industry. Its special properties decompose the clothing oil into diglyceride, monoglyceride and fatty acid and other water-soluble substances, which significantly improve the washing effect of washing powder, especially the effect of removing the macula. We use a variety of enzyme-containing detergents, the enzymes of which mainly include alkaline proteases and alkaline lipases. Alkaline proteases are used to break down proteinaceous stains such as perspiration and blood stains. Alkaline lipase acts mainly on fatty acids and their esters, which is what we usually refer to as oils.

Alkaline Cellulase Enzymes: It can effectively eliminate the long-time wearing and pilling problems during the washing process, to restore the cotton fabric to a smooth, shiny state, making white clothes whiter and colorful clothes more vivid and soft. At the same time, it can also remove particles stained deep in the fiber.

Alkaline amylase: Alkaline proteases are easy to wash away stains such as blood stains and milk stains on clothes. Enzyme washing powder cannot be used for the washing of natural protein fiber fabrics such as silk and wool. Amylase can be used as a detergent in restaurant dishwashers to remove insoluble starch residues and the like.

Alkaline protease: In the daily cleaning, it is mainly used as a decontamination additive in enzymes in detergent powder. Alkaline protease has a high decontamination ability in daily washing, and is often added to detergents because of alkaline protease pairing. : Blood stains, sweat stains, milk stains, oil stains and other protein-based dirt with unique washing effect, it is an industrial additive widely used in the market.
