What is Potassium Stearate ?
Potassium Stearate is also referred to by the name of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in chloroform, ether and carbon disulfide. The aqueous solution is alkaline with phenolphthalein and litmus and the ethanol solution can be slightly acidic to phenolphthalein. It is made by neutralizing the reaction between stearic acid and potassium hydroxide. Commonly utilized in the fabrication detergents, surfactants and softeners. It can also be used in the production of anti-slip material, graphene modified glues Anti-caking agents, waterproof coils.
1 . used to prepare a new type made of material with no slip
The new non-slip material has an excellent wear resistance and anti-slip ability, and the materials used in the formula is readily available for purchase. When it comes to manufacturing, the process is easy and easy to operate, and the manufacturer has an extensive and practical material formula. Materials used in production include small fiber, short fibre, water-based glue, zinc oxideand anti-aging agent the photoinitiator, and stearic Acid. Potassium thermo-stearate, potassium stearate or coupling agent, and carbon fiber, calculated according to the mass percentage. innovative non-slip material contains 5-10 parts of small cord, 0.5-5 percent of water-based glue. zinc oxide, 1-5 parts of antioxidant, 2-8 slices of acids 1-5 parts of photoinitiator Potassium Stearate 10-13 Parts, 1-8 parts of potassium stearate three to ten parts of coupling agents as well as 0.5-10 pieces of carbon fiber.
2 . It is used to make a graphene-modified glue
Graphene is added to the existing glue to alter its resistance to high temperatures 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 the following:
Level 1, the graphene gets added to n'butanol and toluene, the ultrasonic dispersion remains uniform, to make a mixed mixture 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;
3. Step 3, the previous reaction ceases, and the temperature is reduced to 80°C. ethylenediamine is added into the reactor, stirring it evenly, and allowed to stand for one day before obtaining a graphene-modified glue.
3. Preparation , mixing and preparation of composite anticaking agent to be used in food-grade potassium chloride
In order to lessen the chance of having excessive blood pressure it is now possible to add a bit of potassium chloride to replace sodium chloride that is present in the salt. However, during the process of storage and transportation of potassium chloride, the moisture contained in the product promotes the breakdown and recrystallization on the powder's surface. This results in an intergranular bridge in all the pores within the powder as well as the crystals get incorporated together over time to form. Huge mass. The weakening in fluidity can affect its use in table salt. To avoid agglomeration, it's essential to use a suitable amount of anticaking agent to the process of production.
The anticaking agent composite used in food grade potassium chloride is safe, harmless and colorless. It also has no odor. It's comprised 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 is (1.25-5): (0.1-0.4) 1. The purity of D-mannitolcompound, potassium stearate as well as calcium dihydrogen diphosphate, is food grade. As compared to prior art, the invention has the advantages of being completely colorless or white, it does not alter the appearance of the color of potassium chloride. It is free of cyanide, and is non-toxic and safe.
4. . The production of high-molecular-polyethylene waterproof membrane made from polypropylene
Polyethylene polypropylene is a brand new material which has been in use for a while. Polypropylene is a blend of polypropylene non-woven fabrics and polyethylene as the basic raw material. It is made with anti-aging components and compounded by high-tech, new technologyand innovation. The Polypropylene polyethylene composite waterproof roll material with an integrated layer boasts a significant friction coefficient, exceptional quality, durability and a small linear expansion coefficient, extensive temperature adaptability, great weather resistance, chemical resistance, and flexibility. The characteristic is an ideal sustainable product for protecting the environment in the current century. The process for making the waterproofing membrane involves the following steps:
Step 1: Weigh the raw materials using the following parts of weight in the range of 80-130 parts polyethylene resin. Ten to 20 parts of talcum powder. 5-10 parts of silica fume. 5-10 parts of glass bead, and 8-16 pieces of potassium stearate. 8-18 pieces of carboxylated styrene-butadiene latex, 10-20 percent of the anti-aging substance;
Step 2: Place silica fume, talcum powder potassium stearate, carboxylated butadiene-styrene latex into a high-speed mixer. Raise the temperature from 70 to 80 degrees C, then stir it at high speed for 8 to 18 minutes, and then increase the heat to 95-100 degrees Celsius. After that, a glass microbead and polyethylene resin are added to the mix is stirred vigorously at high speed for 10-20 minutes to obtain a combination;
Step 3: Pour the mix into the feeding space, extrude and form the polypropylene sheet and the plastic sheet completely by the three-roller machine. Next, transfer the guide roller to an tractor, cut off the edge, and enter the coiler to create the product.
When compared with earlier art advantageous benefits of this invention are that it creates synergistic effects by an adsorbent polyethylene resin, silica-based fumes and glass microbeads potassium stearate and carboxylated styrene butad the latex, anti-aging substance, and further preparation steps, especially When the high-speed mixing occurs with the proper order of input of the raw material is particularly significant. In combination with the sequence of the invention The performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane will be better than the more conventional membrane for waterproofing with high performance.
