What is Potassium Stearate ?
Potassium-stearate is also referred for its alias "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in chloroform, ether as well as carbon disulfide. The aqueous solutions are strongly alkaline and is phenolphthalein to litmus and the ethanol solution will be slightly alkaline to that of phenolphthalein. It is made by neutralizing the reaction of stearic acid by potassium hydroxide. It is often used in manufacturing of surfactants and fiber softeners. It is also used in the production of anti-slip products, graphene-modified adhesives anti-caking agents, as well as waterproof coils.
1. . used to prepare a new type or non-slip substance
The new non-slip material has high wear resistance and anti-slip performance. The raw materials used in the formula is natural to purchase. In the manufacturing process, the process is easy and straightforward to use, as well as the manufacturer has an extensive and efficient material formula. The production materials are: shorter fibers, glue based on water, the zinc oxide compound, an anti-aging agent, stearic acid, photoinitiator, Potassium thermo-sulfate, potassium stearate or coupling agent, and carbon fiber. Based on its mass percentage. new non-slip materials includes 5-10 parts of shorter cords, 0.5-5 elements of water-based adhesive, 3-7 pieces of zinc oxide 1-5 parts of antioxidant, 2-8 slices of the stearic acids 1-5 pieces of photoinitiator, Potassium Stearate 10-13 parts 1-8 pieces of potassium stearate 3-10 components of coupling, together with 0.5-10 components of carbon fibre.
2 . used to create a graphene-modified glue
The addition of graphene to the existing glue to modify the high-temperature resistance 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 the following:
Level 1: The graphene gets added to n'butanol and toluene, ultrasonic dispersion is uniform. achieve a mixed solutions 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: Above reaction ceases, and the temperature is decreased to 80 deg C, adding ethylenediamine to the reactor, mixed uniformly, and allowed to stand for a day to yield an improved graphene glue.
3. Preparation , mixing and preparation of composite anticaking agent for use in food-grade potassium chloride
To lower the possibility of hypertension, it is now allowed to add part of potassium chloride to replace sodium chloride found in the salt. However, during the process in the storage and transport of potassium chloride in the product encourages breakdown and recrystallization on the material's surface, creating an elongated crystal structure in the pores of the powder, and the crystals are merged with each other as they continue to form. Huge mass. The weakening of fluidity affects its use in table salt. In order to avoid agglomeration, it's required to add an appropriate amount of anticaking agent to the process of production.
The anti-caking compound used in food grade potassium chloride is safe, harmless, colorless, and odorless. It's comprised of D'mannitol along with potassium stearate and calcium dihydrogen phosphate. the specific gravity of D-mannitol, potassium stearate and dihydrogenphosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitolcompound, potassium stearate as well as calcium dihydrogen are food grade. Compared with the prior art this invention has the advantages of being colourless or slightly white, does NOT alter the whiteness of potassium chloride, does not contain cyanide, and is non-toxic and safe.
4. . The process of making high-molecular polyethylene the waterproof membrane is made of polypropylene
Polyethylene Polypropylene is an innovative material which has been in use for a while. Polypropylene is a blend of polypropylene non-woven fabric as well as polyethylene as its primary raw material. It is composed with anti-aging components and blended with high-tech technology, and cutting-edge technology. The polyester polypropylene water-proof roll material that has an integrated layer offers a large friction coefficient, superb quality, durability as well as a very low linear expansion coefficient, wide temperatures, good weather resistance, chemical resistance, and flexibility. This is a fantastic eco-friendly product to protect the environment in the 21st century. The preparation method of the waterproofing membrane involves the following steps:
Step 1: Weigh the raw materials according to the following weights by weight in the range of 80-130 parts polyethylene resin, 10-20 portions of the talcum powder, 5-10 portions of silica-based fume, 5-10 bits in glass beads. There are 8-16 parts of potassium Stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 parts of the anti-aging ingredient;
Step 2: Put talcum powder, silica fume potassium stearate, carboxylated styrene-butadiene in a high-speed mixer. Turn up the temperature to 70 to 80 deg C. Stir at a rapid speed for about 8 to 18 mins, and then raise the heat until it reaches 95-100 degrees C. After that, a polyethylene resin and glass microbeads are added, and the mixture is stirred at high velocity for 10-20 minutes for a mix;
Step 3: Pour the mixture in the feeding area Extrude, then form the polypropylene sheet and the plastic sheet entirely using the three-roller machine, pass one of the guide rollers to the tractor, then cut the edge, and enter the coiler to obtain the product.
In comparison with the existing art advantageous outcomes of the invention are the synergistic effect produced by Polyethylene Resin, Talc, silicon fume, glass microbeads, potassium stearate, carboxylated butadiene latex, anti-aging ingredient, and subsequent preparation steps. particularly when the high-speed mixing occurs using a specific order for the input of the raw material is particularly significant. Together with the sequence of the invention its performance, the made high-molecular polyethylene polypropylene waterproofing membrane outperforms that of the more conventional membrane for waterproofing with high performance.
