What is Potassium stearate
What exactly is Potassium stearate ?
Potassium stearate is also known for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The solution in aqueous form is alkaline, ranging from litmus to phenolphthalein, and the ethanol solution has a slight alkaline form to phenolphthalein. It is made by neutralizing the reaction of stearic acetic acid with potassium hydroxide. It is often used in manufacturing for surfactants as well as fiber softeners. It can also be utilized in the fabrication of anti-slip adhesives, graphene modified glues for anti-caking, anti-caking, and waterproof coils.

Materials used in production include brief fiber, water-based glu zinc oxide, anti-aging agent the photoinitiator, and stearic Acid. Potassium thermo-acetate, potassium stearate coupled agent, carbon fiber. These are calculated in accordance with the mass percentage, this new non-slip material Including 5-10 parts of small cord, 0.5-5 components of water-based glue. 3-7 bits zinc oxide 5 pieces of antioxidant, 2-8 slices of stearic acids, 1-5 parts of photoinitiator Potassium stearate 10-13 parts, 1-8 parts of potassium stearate 3- 10 parts coupling agent and 0.5-10 components of carbon fibre.
2 . It is used to make a graphene-modified glue
The addition of graphene to the existing glue to alter the resistance to high temperatures of the cement and enhance 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 these:
Level 1: The graphene will be added to the n'butanol and toluene, the ultrasonic dispersion is 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 is stopped. the temperature is reduced to 80 deg C, ethylenediamine is added into the reactor, mixed uniformly for a few minutes, then allowed to sit for one day to obtain graphene-modified adhesive.
3. Preparation of anti-caking composites to be used in food-grade potassium chloride
To lessen the possibility of the risk of high blood pressure it's permitted to now add a small amount of potassium chloride , which replaces sodium chloride found in the salt. But, during the process of transportation and storage of potassium chloride in the product can cause breakdown and recrystallization on the powder's surface. This creates crystal bridges within those pores in the powder, and the crystals combine with one another over time to develop. Huge mass. The weakening of fluidity influences its usage in table salt. So, to prevent agglomeration, it is vital to include a proper amount of anticaking agent throughout the production process.
The composite anti-caking agent used in food-grade potassium chloride is safe, harmless colored, and odorless. It's composed of D-mannitol along with potassium stearate and calcium dihydrogenphosphate. the specific gravity of D-mannitol potassium stearate and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of D-mannitol, potassium-stearate and calcium dihydrogen phosphate are food grade. In comparison to the prior art this invention has advantages of being colourless or slightly white, and does not alter the whiteness of potassium chloride. is free of the cyanide element, is non-toxic and non-harmful.
4 . The production of high-molecularly polyethylene waterproof membrane of polypropylene
Polyethylene polypropylene has become a revolutionary material that has recently been utilized. Polypropylene is a blend of polypropylene fabric that is non-woven and polyethylene as the main raw material. It is made by anti-aging agents and processed using the most advanced, high-tech technology, and cutting-edge technology. The polymer polyethylene polypropylene waterproof roll material with an integrated layer is characterized by a high friction coefficients, excellent durability, stability, high mechanical strength Small linear expansion coefficient, large temperatures, good chemical resistance, weather resistance, and flexibility. This makes it a perfect sustainable product for protecting the environment in the new century. The procedure of making the waterproofing of high-molecular polyethylene membrane is as follows:
Step 1: Measure the raw materials in accordance with the following weights by weight (80-130 parts of polyethylene resin; 10-20 parts of talcum powder, 5-10 parts of silica gas, 5-10 portions that are glass beads. Also, 8-16 parts of potassium Stearate. 8-18 pieces carboxylated latex; 10-20 parts of the anti-aging agent;
Step 2: Add talcum powder, silica fume as well as potassium stearate and carboxylated styrenebutadiene latex into high-speed mixer, raise the temperature to 70-80 degrees C. Stir the mixture at high speed for about 8 to 18 mins, and then increase the heat to 95-100 deg C. After that, a glass microbead and polyethylene resin are added, and the mix is stirred vigorously at high speed for about 10-20 minutes in order to get a mixture
Step 3: Transfer the mixture into the feeding zone in order to extrude and create the sheet of polypropylene, and then the plastic sheet entirely using the three-roller machine. Then, connect one of the guide rollers to it, cut the edgeand then go into the coiler to create the finished product.
Compared with the existing art positive benefits of this invention are synergistic results from in the form of polyethylene resin silica fumes, glass microbeads potassium stearate and carboxylated styrene butad latex, anti-aging agents, as well as the subsequent preparation steps. especially When the high-speed mixing takes place using a specific order for the input of the raw materials is extremely vital. When combined with the sequence used in the present invention the performance of the manufactured high-molecular ethylene polypropylene waterproofing membrane exceeds that of the typical high-performance waterproofing membrane.
