What is Potassium stearate
What is Potassium stearate ?
Potassium stearate is also known as "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform or carbon disulfide. The aqueous solution is strongly alkaline and is phenolphthalein to litmus and the ethanol solution has a slight alkaline form to phenolphthalein. It can be made by neutralizing the reactions of stearic and potassium hydroxide. Commonly used in the manufacture in the production of surfactants, fiber softeners and so on. It can also be employed in the manufacturing of anti-slip materials, graphene-modified glues for anti-caking, anti-caking, and waterproof coils.
1. . Used to make a new type in non-slip fabric
The new non-slip surface has outstanding wear resistance as well as anti-slip performance. The raw materials that make up the formula are natural to purchase. In the manufacturing process, the process is easy and user-friendly, and the company has an extensive and efficient formula. Materials used in production include the short-fiber, water-based adhesive the zinc oxide compound, an anti-aging agents, stearic acid, photoinitiator, Potassium thermo-acetate, potassium stearate in combination with coupling agent and carbon fiber, calculated according to the mass percentage, this innovative non-slip material contains: 5-10 parts of length cord 0.5-5 part of water-based glue. Three to seven pieces of zinc oxide, 1-5 antioxidant pieces two to eight slices of stearic acid 1-5 components of photoinitiator Potassium Stearate 10-13 parts 1-8 components of potassium Stearate, 3-10 components of coupling, plus 0.5-10 portions of carbon.
2. . Used to prepare graphene-modified glue
Graphene is included in the existing glue to alter the high-temperature resistance of the 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 these:
Level 1: The graphene gets added to n'butanol and toluene, ultrasonic dispersion is uniform, 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 drops to 80°C. adding ethylenediamine to the reactor, mixed uniformly, and allowed to stand for a day in order to produce the graphene-modified glue.
3. Preparation of a composite anti-caking agent to be used in potassium chloride that is food grade
To reduce the risk of high blood pressure, it is permitted to now add a small amount of potassium chloride to substitute sodium chloride present in the salt. In the process transport and storage of potassium chloride in the product facilitates the dissolution and recrystallization of the powder's surface. It forms crystal bridges within each of the powder's pores as well as the crystals get incorporated in time to form. Huge mass. Fluidity is weakened, which affects its use in table salt. Thus, to keep agglomeration at bay, it is essential to use a suitable amount of anticaking agent during the process of production.
The anticaking agent, a compound, used in food-grade potassium chloride is non-toxic, harmless, colorless, and odorless. It's made of D-mannitol also known as potassium stearate. It is calcium dihydrogen phosphate, wherein the particular gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of the D-mannitolcompound, potassium stearate and calcium dihydrogenphosphate is food grade. In comparison to other known methods this invention offers the advantages of being colorless or slightly white, and does not alter the whiteness of potassium chloride, does not contain cyanide, is non-toxic, and is safe.
4. . The process of making high-molecular polyethylene waterproof membrane made of polypropylene
Polyethylene polypropylene has become a revolutionary material that was recently used. Polypropylene is composed of the non-woven polypropylene fabric, as well as polyethylene is the principal raw material. It is made from anti-aging chemicals and added by high-tech technology, and cutting-edge technology. The polyester polypropylene water-proof roll material with an integrated layer boasts a significant friction coefficient, superb durability, stability, high mechanical strength, small linear expansion coefficientand a broad temperature range of adaptation, outstanding weather resistance, chemical resistance and elasticity. The characteristic is an ideal green environmental protection product in the current century. The procedure of making the waterproofing membrane involves the following steps:
Step 1: Weigh the raw materials in accordance to the following weights by weight in the range of 80-130 parts polyethylene resin; 10-20 parts of Talcum powder, 5-10 pieces of silica gas, 5-10 portions made of glass, as well as 8-16 parts of potassium Stearate. 8-18 pieces made of carboxylated styrene-butad latex, 10-20 components of the anti-aging substance;
Step 2: Mix talcum powder, silica fume along with potassium stearate as well as carboxylated styrene butadiene latex in a high-speed mixer. Adjust the temperature until 70-80 degrees C. Stir the mixture at high speed for 8 to 18 minutes, and then increase the heat to 95 to 100 deg C. Then, polyethylene resin and glass microbeads are added to the mixture is stirred on high velocity for 10-20 minutes to create a mixture;
Step 3: Add the mixture in the feeding area make extrusions and form the sheet of polypropylene, and then the plastic sheet entirely using the three-roller machine, pass an intermediate roller to the tractor, then cut the edge, then go through the coiler to create the finished product.
Comparing to conventional methods, advantageous results of the invention are an effect of synergy between an adsorbent polyethylene resin silica fumes potassium stearate, carboxylated butadiene an anti-aging chemical, and any subsequent preparation steps, particularly when the high-speed mixing takes place at a particular order, the method of introducing the raw materials is particularly important. In combination with the sequence of this invention The performance of the created high-molecular polyethylene and polypropylene waterproofing membrane will be better than the typical high-performance waterproofing membrane.
