Token coins are coin-like objects used instead of coins. Tokens can always be seen in our daily life. Metal token coins are used in lieu of cash in some coin-operated arcade games and casino slot machines.

Railways and public transport agencies used fare tokens for years, to sell rides in advance at a discount, or to allow patrons to use turnstiles geared only to take tokens (as opposed to coins, currency, or fare cards). And the cart tokens in supermarkets are to unlock the trolley. Token coins are also a good tool to promote your logo or brand.

Except for challenge coins, Donghong Craft can also custom token coins for sale. Usually we make token coins by stamping iron with soft enamel for the cheaper cost. But we are also flexible with many other metals like copper, pewter, aluminium, brass and tin and other less durable materials. For the coloring, we can do hard enamel, imitation hard enamel, soft enamel, printing, no coloring. Logos can be 2D or 3D processed. Any shapes are available. Welcome to contact us for more details or quotations for your personalized token coins! Our email is order@dhmedal.com and phone number is +86-769-2290-0190 ext 218.

Application of Cyclohexanone

It is the raw material for the production of caprolactam and adipic acid; used as the solvents and diluent agents of paints, inks, synthetic resins and synthetic rubber; also used as the leather degreasing agent.

Used as the organic solvent;

Raw materials and solvents of synthetic resin and synthetic fiber;

Cyclohexanone is an important chemical raw material, being the major intermediates of making nylon, caprolactam and adipic acid. It is also an important industrial solvent, for example, for paints, especially for those containing nitrocellulose, vinyl chloride polymers, and their copolymers or methacrylate polymer paints. Used as an excellent solvent for pesticides such as organophosphate insecticide. It is used as a solvent for dyes, viscous solvents for piston aviation lubricants, solvents for greases, waxes, and rubbers. Also used as the leveling agent for dyeing and fading silk; degreasing agents for polishing metal; wood coloring paint; also used for cyclohexanone stripping, decontamination, and spot removal. Cyclohexanone and cyanoacetic acid can have condensation reaction to generate cyclohexylidene acetic acid, and then followed by elimination and decarboxylation to get cyclohexene acetonitrile, and finally giving cyclohexene ethylamine by hydrogenation [3399-73-3]. Cyclohexene ethylamine is an intermediate for some drugs.

The solvents for fibers, resins, rubbers, paraffin, shellac, and DDT; for organic synthesis; it can dissolve many of the complexes formed by the elements and organic reagents; bismuth determination; extract rare metal such as uranium, thorium, cobalt, and titanium.

CAS No: 108-94-1

Cyclohexanone solvent is an organic compound and a colorless, transparent liquid with an odor of mud. It will have a minty smell containing phenol. The impuritied cyclohexanone is pale yellow and its color shows with more impurities during the storage period from watery white to grayish yellow. It will generate a strong pungent odor during storage.

Mixed with air, the explosion pole is the same as the open-chain saturated ketone. There has been insufficient evidence that cyclohexanone is the cause of cancer. It is mainly used as an organic synthetic raw material and solvent in the industry. For example, it can dissolve nitrocellulose, paints, and paints. Cyclohexanone is an important chemical raw material and is the main intermediate for the manufacture of nylon, caprolactam, and adipic acid. It is also an important industrial solvent, for example, for paints, especially those containing nitrocellulose, vinyl chloride polymers and their copolymers or methacrylate polymer paints. It is used as an excellent solvent for pesticides such as organophosphorus insecticides and many analogues, a solvent for dyes, a viscous solvent for piston aviation lubricants, and a solvent for greases, waxes, and rubbers. It is also used as a leveling agent for dyeing and matting, as well as polishing.

It is used as a metal degreasing agent, used in the wood coloring paints, cyclohexanone stripping, decontamination, and despeckling, and used as a drug intermediate.

There is the the Difference between Rubber Mat and PVC Coil Mat.

1. Composition and production technology are different: rubber mat is divided into homogeneous and heterogeneous. Homogeneous rubber floor refers to the floor vulcanized by a single or multi-layer structure based on natural rubber or synthetic rubber. Heterogeneous rubber floor refers to floor mat based on natural rubber or synthetic rubber. The PVC coil mat is a carpet made of polyvinyl chloride resin. It uses polyvinyl chloride and its copolymer resin as the main raw material to make, adding filler, plasticizer, stabilizer, colorant, and other accessories. It is made based on the flaky connected base material by uniform mixing, coating or pressing and kneading technology. It can replace pure wool carpet and chemical fiber carpet.

2. The trick is different: As the strong color absorption of rubber, most of the rubber floor mats have a single color; while the PVC coil mats have bright colors, rich drawings, and strong decoration. Especially it is most widely used in decoration.

3. Installation difficulty is different: PVC coil mat is lighter in texture, convenient and fast in the installation; rubber cushion is heavy and hard to install.

4. Market demand and wear resistance are different: rubber flooring is only used in some high-end occasions, and the scale is small; while PVC flooring is widely used because of its super high-cost-performance ratio, and the infinite market potential.

At present, pvc membrane welding machine has been widely promoted in a number of plastic welding industry. Various welding defects are inevitable in the process of use. In this article, it mainly analyzes how to solve the problems in debugging or welding.

1.Crush and bruise

Pressing injury and abrasion are common problems in the process of pvc membrane machine. Sometimes it's not so serious, and it just gets white or marks. When you encounter such problems, the first thing to do is to ensure that the location of the tooling is not out of alignment. First let off the air of the cylinder, press down the welding head, and carefully observe whether the welding head position of the scratch is correct. If the welding head is in the correct position, or if the abrasion or compression occurs on the support (or lower cover), then it is necessary to observe whether there is any interference between the tooling and the product. If it is old tooling, it is suggested to clean the tooling with alcohol at this time. If it is a new fixture, lightly rub the scratch (especially at the bottom of the step) with sandpaper to prevent burrs. In addition, observe whether the air pressure of the cylinder is too large during welding, whether the film of the pad has not been changed for a long time during welding, or whether there are foreign bodies stuck on the film.

If the above work is done, the pressing injury still exists, it can be basically judged as the interference of tooling. At this time, the mold shall be modified according to the size and location of the pressing injury:

(1)slight pressing injury. File the sharp Angle of the tool at the corresponding place of the tool, blunt the sharp Angle of the tool, and then use sandpaper polishing;

(2)the pressing injury is serious, but there is no welding rib at the corresponding place. Rub off the interference part of the fixture with an air abrasive rod (be careful not to touch other parts, especially the root part of the air abrasive rod, which may be rubbed off other places without being noticed). After grinding, make it smooth with whetstone and buff with sandpaper;

(3)severe crush injury. If there is welding rib in the corresponding place, or if there is serious pressing injury and the interference part is very large, please consult with the designer. Have the processing center dealing with the modified drawing and contact the relevant personnel to confirm whether there is a problem with the injection molding, or whether to improve the product structure.

2.Material overflow

If there is any overflow in the welding process of pvc membrane welding machine, do not debug or modify the welding parameters right away. First measure the size after welding, and compare it with the normal value. Adjust according to the difference.

3.Insufficient welding strength

If it is old tooling, first stick the product on the welding head, observe whether the gap between the product and the welding head is too large in the weak welding place, to determine whether the welding head is worn; if it is a new tool, please scan it with the welding head, observe its frequency, power and curve, and make sure there is no problem with the welding head.

We have rammer compactor for sale!

Tamping rammer well known as jumping jack in western countries, it makes up of an engine (motor), a small foot (plate). The jumping jack type is mainly used to compact the backfill in narrow trenches for water or gas supply pipes etc and repair pavements and roads in the small area where the plate compactor and roller compactor are not available to enter into. Rammers have the ability to compact a deeper amount of soil than a plate compactor because the force from the plate is more direct.

The torque generated by the engine or electric motor is transferred to reciprocating motion by crank gear, which will pass it on vibrating foot (shoe) through spring cylinder. It has a strong impact force though it is small and light.

Proper Compaction is very important to prevent soil settlement from happening and result in expensive maintenance cost or structural failure. The soil has complex mixtures. It is consisting of minerals, water, air, organic matter while forming on the land’s surfaces. It is always obviously essential step to do soil compaction as part of the building process in advance. Soil compaction is one of the easiest methods of mechanically increasing the density of soil ground.

It is very similar for upright rammer   and plate compactors. In spite of the fact that the structure is different, the working principle and function same. So when should we choose tamping rammer instead of plate compactor? It is easy to recognize on the accordance of the type of soil. The Tamping rammers work obviously great when compacting cohesive soils because of the small size of the plate. The smaller plate size allows for more focused and direct compaction, which comes in handy on soils that require more force to properly compact. More an can be added to each layer which can make the process of filling and compacting a hole or trench, much faster.

BYCON is one of the most professional tamping rammer manufacturers in China.Please feel free to contact us if you have any further inquiry.

How to remove rtv?

For clothing stained with this RTV silicone, the silicone should be moistened with turpentine to soften it, and then removed with gasoline. For already dry spots, apply cream or artificial butter first, then wipe with gasoline or turpentine, then wipe with 10% ammonia until all the silicone are cleaned. You can also use turpentine to wet the silicone or apply a mixture of white porcelain clay and turpentine to the silicone. After 4 to 5 hours, the RTV silicone can be wiped off and washed with hot soapy water. In addition, the solvent chloroform, turpentine and a mixture of chloroform and carbon tetrachloride (1;1), and a mixture of diethyl ether and ethyl acetate (1;1) are  very effective in removing oil base and dry oil spot.

Such stains on the dyed fabric are first wetted with a pure hot glycerin solution, and then pressed with a cotton ball which touches glycerin tightly on the stain (no rubbing is allowed, rubbing causes changes in the color around the stain).

For such stains on white clothing and non-fading clothing, use concentrated alcohol or concentrated alcohol and a mixture of 5% ammonia in water. When a colored wash stain remains on it, it should be treated with a 3% sodium dithionite solution. When the garment is white cotton and linen, it needs to be removed with an aqueous solution of bleaching powder or an aqueous solution of a mixture of bleaching powder and washing soda ash.

Printing and dyeing sizing wastewater alkali reuse technology patent is the use of ceramic ultrafiltration membrane technology to concentrate sizing wastewater, which permeates directly backs to the sizing process, water and caustic soda are reused fully after treatment resulting in zero discharge. The technology has achieved industrial scale applications and access to a national invention patent.

1. Dyeing and sizing wastewater contains a large amount of refractory slurry, the slurry into the sewage treatment system, increasing the difficulty of biochemical treatment, making sewage treatment costs increase. Printing and dyeing sizing wastewater also contains a higher concentration of caustic soda (0.5% ~ 7%) and a certain amount of refining agent, with a high recovery value.

2. Using uf membrane technology, the printing and dyeing sizing wastewater concentration treatment, membrane treatment of the permeate directly to the sizing process, including water and caustic soda, etc. can be completely reused to achieve zero discharge of sewage treatment.

Refined water from a dying plant in Nantong is treated by ceramic membrane technology, project design daily capacity is 500m3 or more, yield meets the workshop reuse requirements.

INDIGO RECOVERY

The dye wastewater containing indigo is characterized by a dark blue color due to the presence of the dye not fixed to the fiber during the dyeing process.

The primary use for indigo is as a dye for cotton yarn, which is mainly for the production of denim cloth for blue jeans.

The wastewater containing indigo is characterized by a moderate amount of chemical oxygen demand (COD), pH, suspended solids, dissolved solids and a dark blue color, due to the presence of the dye not fixed to the fiber during the dyeing process.

JIUWU HI-TECH utilizes the unique integrated membrane systems for dye wastewater treatment, which recover the insoluble indigo dye, the production of a secondary commercial product from the waste stream through a by-product synergy process offers an attractive alternative to discharging the untreated effluent into municipal treatment plants or the environment.

WASHING EFFLUENTS

Washing is a finishing process applied to fibres, yarns, and fabrics.

Washing is normally carried out in hot water (40-100°C) in the presence of wetting agent and detergent. The detergent emulsifies the mineral oils and disperses the undissolved pigments. The choice of the surfactants may vary also depending on the type of fibre. Mixtures of anionic and non-ionic surfactants are commonly used. An important factor in the selection of a surfactant is its effectiveness in strongly alkaline conditions.

Washing effluents are mainly composed of soap, grease, synthetic detergents, detergents and a small amount of bacteria, coliform bacteria, viruses, and other harmful substances, has become an important source of water pollution.

After washing effluents are discharged into natural water, dissolved oxygen is consumed and slightly toxic to aquatic organisms, which can cause fish malformation and eutrophication caused by phosphate solvent.
