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 of silica gel, 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 silica gel chemical formula     and physical structure 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.

 

GOLOHO POLYMER was founded in China, setting up factory to develop and produce rtv grease. Now the company embraces united and dynamic team, experienced R&D center, advanced detection method, strong manufacture capacity as well as customer-oriented service. We sincerely invite and welcome people from all around the world to invest and create more values together.

WINE AND LESS

Membrane crossflow filtration is becoming the unique alternative to kieselguhr filters in wine industry with the developments in environmental and health regulations.

 

Membrane crossflow filtration is widely used in wine membrane filter system for wine filtration, especially as the red wine filter. It can also be used for cross flow filtration beer. Now, the membrane crossflow filtration technology potential for energy-efficiency has made it a viable technique for the clarification of wine and other beverages.

 

Crossflow filtration uses a selectively porous ceramic membrane that filters a liquid in order to purify or clarify it. The quality of the filtration is constant over time because the fouling is reduced because the filtering is made without any change of state of the filtered element, and never gets distorted. Membrane crossflow filtration is one of the environmentally-friendly wine filtration systems. During the filtration, no filter aid is used. In one step, crossflow filtration clarifies the wine, giving it a clear appearance and making the wine microbiologically stable. So it has very strong advantages in simplifying the steps before bottling and reducing or eliminating the need for some consumables.

 

Advantages:

Stable filtrate quality

Maximum guarantee the sensory properties of the wine

Optimized process

No filter aids required

High yield

Reduced filtration costs & product losses

Smart, compact, small footprint

Introduction to Impulse Welding

 

Impulse refers to the welding current waveform is discontinuous, current size changes.

 

Generally speaking, pulse type spot welder refers to the sinusoidal alternating current is SCR, divided into sections of current, commonly known as pulse welder. In other words, pulse mode of operation refers to the mode of operating only once every certain interval.

 

At present, single pulse and double pulse are mostly used in welding.

 

Conventional pulse gas welding: only one pulse. All the peaks of a monopulse are the same like NNNNN. Pulse gas welding machine is the use of pulse current to achieve droplet transition welding mode, no splash, deep penetration, fine grain, high weld strength, suitable for all-position welding, from 20 a to 500A can achieve stable quality welding, welding performance is far better than the ordinary gas welding machine, is the mainstream direction of welding machine development. Double pulses are equivalent to the superposition of two single pulses with the same period and different phases. In other words, one period may have two peaks: nNnNnN.

 

Double pulse gas shielded welding is a welding method developed on the basis of pulse gas shielded welding. It is a welding method with alternating changes of two pulse gas shielded welding methods with different current sizes. It is mainly used in the welding of aluminum alloy, and it can produce the effect of fish-scale pattern without swing, similar to the effect of ac TIG welding. In addition, this welding method can effectively control the heat input, which is similar to the pulsed argon arc. It can be fully welded without penetration, and is suitable for all metal welding.
