What is Potassium stearate

What is Potassium Stearate ?

Potassium stearate may also be referred as "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution tends to be alkaline in comparison to phenolphthalein or litmus and the ethanol solution will be slightly alkaline to that of phenolphthalein. It is made by neutralizing the reaction between stearic acid and potassium hydroxide. Commonly used in the manufacture of fiber softeners and surfactants. It can also be utilized to make anti-slip material, graphene modified glues, anti-caking agents, and waterproof coils.

1 . It is used to create a brand new type in non-slip fabric

The non-slip new material comes with great wear resistance and antislip performance. The raw ingredients in the formula are organic and easy to obtain. It is produced using the procedure is easy and straightforward to use, and the company has a large and convenient material formula. The production materials are: shorter fibers, glue based on water zinc oxide, anti-aging agent, stearic acid, photoinitiator, Potassium thermo-stearate, potassium stearate also known as coupling agent. Carbon fiber. Measured according to the mass percentage. is a brand new non-slip substance that includes 5-10 parts of the fiber, 0.5-5 three parts water-based glue. zinc oxide 5 pieces of antioxidant, 2-8 strips of stearic acid 1-5 pieces of photoinitiator Potassium Stearate 10-13 Parts, 1-8 pieces of potassium stearate, 3- 10 parts coupling agent, plus 0.5-10 components of carbon fibre.

2. . used to create a graphene-modified glue

The addition of graphene to the existing glue to modify its resistance to high temperatures cement and increase 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 specific steps are as follows:

Level 1: The graphene is mixed with n-butanol and toluene, the ultrasonic dispersion is uniform to get a mixed solution;

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 is stopped, and the temperature decreases to around 80 degrees Celsius. an ethylenediamine solution is added to reactor, stirred thoroughly for a few minutes, then allowed to sit for one day before obtaining an unmodified graphene glue.

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

To lower the risk of hypertension, it is now permitted to add a portion of potassium chloride as a replacement for sodium chloride found in the salt. But, during the process of transportation and storage for potassium chloride, the moisture in the product facilitates the decomposition and recrystallization powder surface, thereby forming crystal bridges at its pores, and crystals are then bonded in time to form. Huge mass. The weakening in fluidity can affect its usage in table salt. Thus, to stop agglomeration from occurring, it is essential to use a suitable amount of anti-caking agent in the production process.

The anti-caking ingredient that is used in food grade potassium chloride is non-toxic harmless, colorless, and odorless. It's composed of D-mannitol in combination with potassium stearate as well as calcium dihydrogen phosphate, wherein the particular gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium stearate and calcium dihydrogen phosphate are food grade. In comparison to other known methods it has the advantages of being colorless or lightly white, does not alter the color of potassium chloride, is free of cyanide, is safe, and non-harmful.

4 . The process of preparing high-molecular Polyethylene the waterproof membrane is made of polypropylene

Polyethylene Polypropylene, a new substance that has come into use in recent years. Polypropylene is a blend of polypropylene non-woven fabric as well as polyethylene as its primary raw material. It is composed of anti-aging ingredients and created by high-tech, modern technologies and advanced technology. The polymer polyethylene and polypropylene composite waterproof roll material with an integrated coating has a huge friction coefficient, great stability, high mechanical strength, small linear expansion coefficient, broad temperature range of temperature adaptation, superb weather resistance, chemical resistance and elasticity. This is a fantastic eco-friendly product to protect the environment in the new century. The process of making the waterproofing of high-molecular polyethylene membrane comprises of the following steps:

Step 1: Weigh the raw materials in accordance with the following percentages by weight in the range of 80-130 parts polyethylene resin. Also, 10-20 percent of the talcum powder, 5-10 portions of silica fume. Five to ten parts of glass beads, and 8-16 pieces of potassium stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 parts of anti-aging agents.

Step 2: Put silica fume, talcum powder, potassium stearate and carboxylated butadiene-styrene latex into a high-speed mixer. Raise temperatures to 70-80 degrees C. Mix at a fast speed for between 8 and 18 minutes, and then increase the heat up to 95-100 deg Celsius. After that, a glass microbeads made of polyethylene are added and the mixture is stirred at a rapid speed for about 10 to 20 minutes to create a mixture;

Step 3: Transfer the mixture into the feeding zone Extrude, then form the sheets of polypropylene and plastic sheet fully using the three-roller machine, pass the guide roller on it, cut the edges and then insert the coiler to create the finished product.

Compared with the previous art beneficial results of the invention comprise Synergistic effect from in the form of polyethylene resin, silica fumes, glass microbeads, potassium stearate anti-aging agent, latex and any subsequent preparation steps, especially When the high-speed mixing occurs using a specific order for the input of the raw materials is extremely vital. When combined with the sequence of the invention its performance, the produced high-molecular Polyethylene polypropylene waterproofing membrane far exceeds that of the standard high-performance waterproofing membrane.
