What is Potassium Stearate ?
Potassium stearate can also be referred to for its alias "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in chloroform, ether as well as carbon disulfide. The solution that is aqueous is alkaline and is phenolphthalein to litmus and the ethanol mixture is slightly alkaline to phenolphthalein. It is obtained by neutralizing the reaction between stearic acid and potassium hydroxide. It is often used in manufacturing in the production of surfactants, fiber softeners and so on. It is also utilized in the manufacture of anti-slip materials, graphene -modified glues, anti-caking agents, and waterproof coils.
1. . It is used to create a brand new kind in non-slip fabric
The new non-slip material has high wear resistance and anti-slip performance, and the raw materials that make up the formula are easy to acquire. The manufacturing process is the procedure is easy and straightforward to use, and the company has a large and convenient material formula. The production materials are: the short-fiber, water-based adhesive, zinc oxide(zinc oxide), anti-aging agent, the photoinitiator, and stearic Acid. Potassium stearate, potassium, coupling agent and carbon fiber. All of these are calculated according to the mass percentage, this new non-slip materials includes 5-10 parts of the small cord, 0.5-5 portions of glue based on water, 3-7 parts of zinc oxide, 5 pieces of antioxidant, 2-8 slices of the stearic acids 1-5 parts of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 parts potassium stearate 3-10 parts of coupling agent, as well as 0.5-10 part of carbon.
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 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 specific steps are as below:
Level 1, the graphene is mixed with n-butanol and toluene. The ultrasonic dispersion is uniform, in order 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;
3. Step 3, the previous reaction ceases, and the temperature is lowered 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 an improved graphene glue.
3. Preparation of a composite anti-caking agent to be used in potassium chloride food grade
In order to lessen the risk of increased blood pressure it's now possible to add a bit of potassium chloride to substitute sodium chloride in the food salt. However, during the process transport and storage of potassium chloride, the moisture contained within the product stimulates recrystallization and dissolution of the powder's surface. This creates an elongated crystal structure in porous areas of powder and the crystals then combine to form a crystal bridge over time. to develop. Huge mass. The weakness of fluidity affects its usage in table salt. To avoid agglomeration, it's important to add a sufficient amount of anti-caking agent in the production process.
The anticaking agent, a compound, used in food grade potassium chloride is non-toxic harmless, colorless, and odorless. It's composed of D-mannitol also known as potassium stearate. It is calcium dihydrogenphosphate. 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 the D-mannitols, potassium stearates, and calcium dihydrogenphosphate is food grade. As compared to prior art it offers advantages of being colorless or slightly white, does NOT alter the whiteness of potassium chloride, is free of cyanide, and is non-toxic and non-harmful.
4 . The process of preparing high-molecular Polyethylene polyester waterproof membrane
Polyethylene polypropylene is a brand new material which has been in use for a while. Polypropylene is made up of non-woven polypropylene fabric and polyethylene as the primary raw material. It is made by anti-aging agents and compounded by high-tech, new technological advancements and new technologies. The polymer polyethylene polypropylene composite water-proof roll material that has an integrated layer has significant friction coefficient, excellent durability, stability, high mechanical strength as well as a very low linear expansion coefficient, extensive temperature adaptation range, excellent weather resistance, chemical resistance and flexibility. This makes it an ideal environmentally-friendly protection product for the current century. The preparation method of the waterproofing high-molecular polyethylene polypropylene membrane is as follows:
Step 1: Measure the raw materials in accordance with the following weights by weight in the range of 80-130 parts polyethylene resin, 10-20 pieces of talcum powder. Five to 10 parts of silica fume. 5-10 parts made of glass, as well as 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 pieces of the anti-aging substance;
Step 2: Add talcum powder, silica fume, potassium stearate and carboxylated styrenebutadiene latex into high-speed mixer. Adjust the temperature from 70 to 80 degrees C. Mix at a fast speed for 8 to 18 minutes, and then raise the heat to 95 to 100 deg C. After that, a glass microbeads made of polyethylene are added and the mixture is stirred at a high speed for about 10 to 20 minutes to obtain a combination;
Step 3: Put the mix into the feeding space Extrude and then form the polypropylene sheet and the plastic sheet completely with the 3-roller machine. Transfer the guide roller onto the tractor, cut the edge, and enter the coiler to create the final product.
As compared to the prior art, the positive results of the invention are the synergistic effects of materials such as polyethylene resin, silica-based fumes and glass microbeads, potassium stearate in the form of anti-aging and latex and subsequent preparation steps. particularly when the high-speed mixing process is being carried out by a sequence of introducing the raw materials is extremely vital. When combined with the sequence of the invention it is evident that the performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane surpasses that of the typical high-performance waterproofing membrane.
