What is Potassium Stearate ?
Potassium stearate is also known by the name of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in chloroform, ether or carbon disulfide. The aqueous solution is alkaline to litmus and phenolphthalein and the ethanol mixture is slightly alkaline to phenolphthalein. It can be made by neutralizing the reaction of stearic acids with potassium hydroxide. Commonly , it is used in the manufacturing for surfactants as well as fiber softeners. It is also used in the creation of anti-slip materials, graphene -modified glues in addition to anti-caking and waterproof coils.
1. . It is used to create a brand new type of non-slip material
The brand new non-slip product has outstanding wear resistance as well as anti-slip performance. Furthermore, the raw materials in the formula are easy to acquire. It is produced using the method is simple and simple to use, and the manufacturer provides an extensive and efficient formula. Materials used in production include small fiber, short fibre, water-based glue, zinc oxideas well as anti-aging agent, photoinitiator, stearic acids, Potassium thermo-sulfate, potassium stearate, coupling agent and carbon fiber, calculated according to the mass percentage. This non-slip new material comprises 5-10 parts of short cord, 0.5-5 portions of glue based on water, 3-7 parts of zinc oxide one to five pieces of antioxidant, 2- 8 slices of Stearic acid 1-5 pieces of photoinitiator, Potassium Stearate 10-13 parts 1-8 components of potassium Stearate 3-10 parts of coupling agent, along with 0.5-10 bits of carbon.
2 . used to prepare a graphene-modified glue
Graphene is incorporated into the existing glue to alter the high-temperature resistance of cement as well as 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 steps specific to HTML0 are as these:
Level 1, the graphene will be added to the n'butanol and toluene, 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;
Step 3: the above reaction is stopped. the temperature is decreased to around 80 degrees Celsius. adding ethylenediamine to the reactor, which is stirred continuously and then left to stand for one day to obtain one graphene-modified gluing.
3. Preparation of a composite anti-caking agent for use in food-grade potassium chloride
To reduce the risk of the risk of high blood pressure it's currently allowed to add some of potassium chloride that replaces sodium chloride that is present in the salt. But, during the process to store and transport potassium chloride, the moisture in the product facilitates the melting and recrystallization powder's surface. This results in crystal bridges in its pores and crystals are then bonded with each other over time to form. Huge mass. The weakening of fluidity influences its usage in table salt. In order to prevent agglomeration, its crucial to add the correct amount of anticaking agent during the production process.
The anti-caking compound used in food-grade potassium chloride is safe, harmless in its color, odor, and colorlessness. It's made up of D mannitol also known as potassium stearate. It is calcium dihydrogen phosphate, wherein the specific gravity of D'mannitol potassium stearate, and dihydrogen phosphate are (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 this invention has the advantages of being colourless or slightly white, does NOT alter the brightness of potassium chloride. is free of cyanide, is not toxic, and is safe.
4 . The preparation of high-molecular polyethylene polypropylene waterproof membrane
Polyethylene polypropylene is a new substance that has come into use in recent years. Polypropylene is a blend of polypropylene non-woven fabrics and polyethylene as the main raw material. It is made with anti-aging components and created by high-tech, modern technologyand innovation. The Polymer Polyethylene Polypropylene Composite waterproof roll material that has an integrated coating has a huge friction coefficients, high durability, stability, high mechanical strength and a small linear expansion coefficient, a wide temperature range for temperature adaptation, superior chemical resistance, weather resistance and flexibility. This is a fantastic environmentally friendly product for the 21st century. The preparation method of the high-molecular ethylene polypropylene waterproofing membrane involves the following steps:
Step 1: Measure the raw materials using the following parts by weight including 80-130 ppm of polyethylene resin, 10-20 pieces of talcum powder. 5-10 parts of silica fume, 5-10 pieces of glass bead, and 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated styrene-butadiene latex, 10-20 portions of the anti-aging ingredient;
Step 2: Pour silica fume, talcum powder potassium stearate, carboxylated styrene butadiene latex in a high-speed mixer, raise temperatures to 70-80 degrees C, stir at high rate for between 8 and 18 min, and then increase the heat to 95 to 100 degrees Celsius. Following that, polyethylene resin and glass microbeads are added, and the mixture is stirred up at a high speed for about 10 to 20 minutes until you get a perfect mixture.
Step 3 : Put the mixture into the feeding area Extrude and then form the polypropylene sheet and the plastic sheet entirely using the three-roller machine. Then, connect the guide roller onto an tractor, cut off the edgeand then go into the coiler to get the product.
In comparison to the earlier art positive advantages of the invention include the synergistic effects of plastic resins, such as talc silica fumes, glass microbeads potassium stearate, carboxylated butadiene latex, anti-aging ingredient, and the subsequent steps to prepare, especially when high-speed mixing occurs at a particular order, the method of introducing ingredients is particularly important. In conjunction with the sequence of the invention it is evident that the performance of the produced high-molecular Polyethylene polypropylene waterproofing membrane outperforms that of the conventional high-performance waterproofing membrane.
