Why can calcium stearate film at high temperature?
What is calcium stearate?
Calcium stearate white powder is insoluble in water, cold ethanol, and ether, in hot benzene, turpentine, and other organic solvents, and slightly soluble in hot ethanol and ether. When heated to 400 ℃, it slowly decomposes, is flammable, and decomposes into stearic acid and corresponding calcium salt when meeting strong acid, with hygroscopicity. Its other name is calcium stearate; Calcium octadecanoate; Calcium octadecylate, calcium octadecylate; SCD lubricant; Calcium octadecanate. As a kind of calcium carbonate, it is very easy to produce dust in production, so it is necessary to operate in a closed manner and pay attention to ventilation. Operators must receive special training and strictly follow the operating procedures. It is recommended that operators wear self-priming filter dust masks and chemical safety goggles. Keep away from kindling and heat sources. Smoking is prohibited in the workplace. Use explosion-proof ventilation systems and equipment to avoid dust. Avoid contact with oxidants. Handle with care to prevent damage to packaging and containers.
Use of calcium stearate
1. Calcium stearate can be used as a plasticizer in rubber processing, softening natural rubber and synthetic rubber, but has little effect on vulcanization. It is also used as a thickener for lubricating grease, a waterproof agent for textiles, a leveling agent for paint, and a plasticizer for making plastic records
2. It is used for food packaging, medical equipment, and other non-toxic soft film and equipment. It can also be used as a halogen absorbent for polyethylene and polypropylene to eliminate the adverse effect of residual catalysts on color and stability
3. As a non-toxic stabilizer for PVC, it has small initial coloration and good weather resistance. This product is not easy to use alone because it has an obvious catalytic effect on the degradation of PVC. After some time, it can make the product change color rapidly. It is used in general soft products in cooperation with barium cadmium soap. The amount of the product is not easy to be too large, but when used with epoxy compounds and phosphorous esters, its amount can be appropriately increased.
Preparation of calcium stearate
The production process of calcium stearate mainly includes the double decomposition method and the one-step method. The reaction conditions of the double decomposition method are mild to obtain metal soap products with good color and high purity. Due to the large gelling energy and small solubility of sodium soap, it is easy to combine with stearic acid to form acid soap. The double decomposition method to prepare calcium stearate requires a large amount of water to reduce the viscosity of the reaction material. It has the disadvantages of low production efficiency, a large amount of saline wastewater discharge, and large water consumption. With the increasing environmental protection awareness, The saponification double decomposition process, which is a production process of calcium stearate with high raw material consumption, high energy consumption, and serious environmental pollution, is bound to withdraw from the historical stage.
Price of calcium stearate
Calcium stearate particle size and purity will affect the product's price, and the purchase volume can also affect the cost of calcium stearate. A large amount of large amount will be lower. The price of calcium stearate can be found on our company's official website.
