What is Potassium stearate

What is Potassium stearate ?

Potassium is also known for its alias "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in chloroform, ether and carbon disulfide. The aqueous solution tends to be alkaline to phenolphthalein or litmus, and the ethanol solution has a slight alkaline form to phenolphthalein. It is produced by neutralizing the reaction of stearic Acid with potassium hydroxide. It is frequently used in the making of surfactants and fiber softeners. It can also be used in the creation of anti-slip adhesives, graphene modified glues as well as anti-caking agents and waterproof coils.

1 . utilized to prepare a completely new type that is non-slip.

The brand new non-slip product has robust wear resistance and anti-slip performance. Additionally, the raw components in the formula are simple to buy. In the production process, the procedure is easy and simple to use, and the manufacturer uses an extensive and efficient formula. Production materials include: short fiber, water-based glue, zinc oxide, antioxidant agents, stearic acid, photoinitiator, Potassium thermo-sulfate, potassium stearate the coupling agent as well as carbon fiber. Measured according to the mass percentage, this non-slip new material comprises 5-10 parts of the small cord, 0.5-5 elements of water-based adhesive, 3-7 pieces zinc oxide, 1-5 antioxidant pieces, 2-8 slices of the stearic acid 1-5 pieces of photoinitiator Potassium Stearate 10-13 Parts, 1-8 pieces of potassium stearate, 3-10 components of coupling in addition to 0.5-10 part of carbon.

2. . Used to prepare graphene-modified glue

Graphene is added to existing glue to modify the resistance to high temperature of the cement and to improve its adhesion. The material for preparing the paste is calculated by parts by weight: 12-30 parts of polyurethane, 15-30 parts of chloroprene rubber, 15-30 parts of polyacrylate, 2-12 parts of graphene, triallyl isocyanuric acid 0.8-1.6 parts of ester, 1-6 pieces of ethylenediamine, 2-10 parts of n-butanol, 2-8 pieces of toluene, 0.8-3 parts of potassium stearate, 2-8 parts of polyvinylpyrrolidone, N- 1-5 parts of phenyl-b-naphthylamine;

The steps specific to HTML0 are as these:

Level 1, the graphene component is added to nbutanol and toluene. The ultrasonic dispersion remains uniform, to obtain a mixed solution A;

Step 2, adding polyurethane, chloroprene rubber, and polyacrylate into the reactor, the temperature is raised to 80-105 deg C, the reaction is 1-3 hours, and then the mixed solution A and triallyl isocyanurate in the first step The acid ester, potassium stearate, polyvinylpyrrolidone, and N-phenyl-b-naphthylamine are sequentially added to the reactor, the reaction temperature is adjusted to 150-360 deg C, and the reaction is carried out for 2-5 hours to obtain a mixture B;

Step 3: The above reaction ceases, and the temperature is reduced to around 80 degrees Celsius. an ethylenediamine solution is added to reactor, which is stirred continuously and left to stand for a few days to create the graphene-modified glue.

3. Preparation , mixing and preparation of composite anticaking agent to be used in food-grade potassium chloride

To lessen the risk of excessive blood pressure it is now possible to add a bit of potassium chloride that replaces sodium chloride in the food salt. In the course that involves the storage and transportation of potassium chloride, the moisture contained in the product facilitates the melting and recrystallization powder's surface. This creates a crystal bridge at these pores and the crystals combine together over time to form. Huge mass. The weakening of fluidity influences its usage in table salt. Thus, to stop agglomeration from occurring, it is crucial to add the correct amount of anti-caking agent during the production process.

The anticaking additive used in food grade potassium chloride is safe, harmless and colorless. It also has no odor. It's made of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate are (1.25-5): (0.1-0.4) 1. The purity of D-mannitol, potassium stearate and calcium dihydrogen and phosphate is food grade. Comparatively to prior art the invention has advantages of being colourless or slightly white, does NOT alter the hue of the potassium chloride and is free of cyanide, is safe, and non-harmful.

4 . The production of high-molecularly polyethylene polyester waterproof membrane

Polyethylene polypropylene is a brand new substance that has come into use in recent years. Polypropylene is made up of the non-woven polypropylene fabric, as well as polyethylene for the primary raw material. It is made of anti-aging ingredients and manufactured using high-tech, advanced technology, and new technology. The Polymer Polyethylene Polypropylene Composite waterproof roll material with an integrated layer has significant friction coefficient, outstanding stability, high mechanical strength, small linear expansion coefficient, wide temperature range of adaptation, outstanding chemical resistance, weather resistance and flexibility. This is a fantastic eco-friendly product to protect the environment in the new century. The method for making the high-molecular-molecular-molecular-polyethylene waterproof membrane comprises the following steps:

Step 1: Measure the raw materials in accordance to the following weights by weight in the range of 80-130 parts polyethylene resin. Ten to 20 parts of talcum powder. 5-10 parts of silica gas, 5-10 portions made of glass, as well as 8-16 parts of potassium stearate. 8-18 pieces of carboxylated latex, 10-20 percent of anti-aging agents;

Step 2: Place talcum powder, silica fume potassium stearate, carboxylated styrene-butadiene latex into a high-speed mixer. Then, increase the temperature from 70 to 80 degrees C. Stir the mixture at high speed for 8 to 18 min, and then raise the heat to 95-100 deg C. After that, a glass microbeads and polyethylene resin are added to the mixture is stirred up at a high speed for about 10-20 minutes to make a blend;

Step 3: Put the mixture into the feeding area create the extrusion and sheets of polypropylene and plastic sheet completely with the help of the three-roller machine, pass the guide roller through the tractor, trim the edge, then go through the coiler to create the final product.

Compared with the conventional methods, beneficial advantages of the invention include an effect of synergy between materials such as polyethylene resin, silicon fume, glass microbeads potassium stearate, carboxylated styrene-butadiene latex, anti-aging agent, as well as the subsequent preparation steps. especially When the high-speed mixing is carried out, the order of inputting the raw materials is particularly important. In conjunction with the sequence of the invention, the performance of the prepared high-molecular polyethylene polypropylene waterproofing membrane can be superior the standard high-performance waterproofing membrane.
