What is Potassium stearate

What is Potassium stearate ?

Potassium-stearate is also referred as "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform and carbon disulfide. The aqueous solution appears to be alkaline and is phenolphthalein to litmus The ethanol solution tends to be alkaline with phenolphthalein. It can be made by neutralizing the reactions of stearic and potassium hydroxide. Commonly , it is used in the manufacturing from surfactants and fibre softeners. It is also employed in the manufacturing of anti-slip adhesives, graphene modified glues also known as anti-caking substances, as well as waterproof coils.

1. . The 1 is used to design a different type of slip-resistant material

The latest non-slip fabric has great wear resistance and antislip ability, and the components in the formula are easily available for purchase. The manufacturing process is the process is easy and simple to use, as well as the manufacturer has a large and convenient material formula. The production materials are: short fiber, water-based glue, zinc oxide, anti-aging agent, photoinitiator, stearic acid Potassium stearate, potassium coupled agent, carbon fiber. All of these are calculated according to the mass percent, this novel non-slip product includes 5-10 parts of the shorter cords, 0.5-5 elements of water-based adhesive, 3-7 pieces zinc oxide, one to five pieces of antioxidant 2-8 slices , stearic acid 1-5 components of photoinitiator, Potassium Stearate 10-13 parts 1-8 pieces of potassium stearate, 3-10 components of coupling, plus 0.5-10 bits of carbon.

2. . Used to prepare graphene-modified glue

Graphene is included in the existing glue to alter the high-temperature resistance of the cement and 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 specific steps are as they are:

Level 1: The graphene is mixed with n-butanol and toluene. Ultrasonic dispersion is uniform. produce 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 is lowered to 80°C. an ethylenediamine solution is added to reactor, mixed uniformly and left to stand for a whole day to make an unmodified graphene glue.

3. Preparation of a composite anti-caking agent for use in food-grade potassium chloride

In order to lessen the risk of high blood pressure, it's now allowed to add part of potassium chloride to replace sodium chloride present in the salt. In the process of transportation and storage of potassium chloride contained in the product can cause breakdown and recrystallization on the porous surface of the powder, resulting in crystal bridges at each of the powder's pores, and the crystals are merged with one another over time to form. Huge mass. The weakness of fluidity affects the use of table salt. Therefore, in order to avoid agglomeration, it's imperative to add the right amount of anticaking agent during the production process.

The anti-caking compound used in food-grade potassium chloride is non-toxic harmless in its color, odor, and colorlessness. It is composed of D-mannitol, potassium stearate, and calcium dihydrogen phosphate. the specific gravity of D-mannitol, potassium stearate and dihydrogen phosphate are (1.25-5): (0.1-0.4): 1. The purity of D-mannitols, potassium stearates, as well as calcium dihydrogen diphosphate, is food grade. In comparison to other known methods this invention has advantages of being colorless or slightly white, and does not alter the hue of the potassium chloride and is free of any cyanide or other toxic elements, and is completely safe and safe.

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

Polyethylene polypropylene is a new material which has been in use for a while. Polypropylene is made of polypropylene non-woven fabric and polyethylene as the primary raw material. It is composed with anti-aging components and made by the latest high-tech technology, and new technology. The Polypropylene polyethylene composite waterproof roll material with an integrated layer has a substantial friction coefficient, exceptional stability, high mechanical strength small linear expansion coefficientand a broad temperature range for temperature adaptation, superior chemical resistance, weather resistance and elasticity. This makes it a perfect green product for environmental protection in the current century. The preparation method of the high-molecular polyethylene polypropylene waterproofing membrane comprises of the following steps:

Step 1: Weigh the raw materials in accordance with the following parts by weight that is 80-130 parts of polyethylene resin. Also, 10-20 percent of Talcum powder, 5-10 pieces of silica fume. 5-10 parts in glass beads. There are 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated latex and 10-20 parts of anti-aging agents;

Step 2: Place silica fume, talcum powder potassium stearate, carboxylated latex of styrene and butadiene into high-speed mixer. Increase the temperature to 70-80 deg C, then stir it at high speed for about 8 to 18 mins, and then increase the heat until it reaches 95-100 degrees C. Following that, polyethylene resin and glass microbeads are added, and the mixture is stirred at a rapid speed for about 10 to 20 minutes to create a mixture;

Step 3: Add the mixture into the feeding area Extrude, then form the sheet of polypropylene as well as the plastic sheet completely with the help of the three-roller machine. Pass one of the guide rollers to your tractor, then cut the edge, then go through in the coiler machine to produce the finished product.

As compared to the earlier art advantageous benefits of this invention are synergistic results from in the form of polyethylene resin, silica fumes, potassium stearate and carboxylated styrene butad the latex, anti-aging substance, and further preparation steps, especially when high-speed mixing occurs, the order of inputting the raw materials is especially vital. When combined with the sequence of the invention its performance, the created high-molecular polyethylene and polypropylene waterproofing membrane will be better than that of the conventional high-performance waterproofing membrane.
