What is Potassium stearate ?
Potassium stearate may also be referred for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution appears to be alkaline with phenolphthalein and litmus while the ethanol solution may be slightly alkaline in comparison to phenolphthalein. It can be obtained by neutralizing the reactions of stearic and potassium hydroxide. It is often used in manufacturing of softeners for fibers and other surfactants. It can also be used in the production of anti-slip substances, graphene-modified glues, anti-caking agents, and waterproof coils.
1 . This is used to create a novel type or non-slip substance
The new non-slip material has an excellent wear resistance and anti-slip performance. The raw materials that make up the formula are readily available for purchase. The manufacturing process is the procedure is easy and easy to follow, and the manufacturer uses an extensive and efficient formula. Production materials include: Short fiber, water-based glue, the zinc oxide compound, an anti-aging substance, photositiator, stearic, Potassium thermo-sulfate, potassium stearate the coupling agent as well as carbon fiber. Calculated based on the mass percentage. non-slip new material comprises: 5-10 parts of shorter cords, 0.5-5 part of water-based glue. Three to seven pieces zinc oxide, 1- 5 parts of antioxidant, two to eight slices of stearic acid 1-5 components of photoinitiator Potassium stearate 10-13 parts, 1-8 parts potassium stearate 3-10 elements of coupling, together with 0.5-10 parts of carbon fiber.
2. . used to create a graphene-modified glue
Graphene is added to the existing glue to alter the high-temperature resistant of the cement and increase 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 they are:
Level 1, the graphene gets added to n'butanol and toluene, the ultrasonic dispersion of the mixture is uniform to 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: The previous reaction ceases, and the temperature is brought down to 80 deg C, in the step 3, ethylenediamine enters the reactor, stirred thoroughly and then left to stand for a day to yield graphene-modified adhesive.
3. Preparation of anti-caking composites to be used in potassium chloride food grade
To decrease the possibility of higher blood pressure it is currently permitted to add a little of potassium chloride as a replacement for sodium chloride in the edible salt. In the process of transportation and storage of potassium chloride, the moisture contained in the product causes dissolution and recrystallization of material's surface, creating crystal bridges within porous areas of powder, and the crystals then combine with one another over time to form. Huge mass. The weakening of fluidity affects its usage in table salt. Therefore, in order to avoid agglomeration, it's necessary to add an appropriate amount of anticaking agent during the production process.
The anti-caking ingredient that is used in food grade potassium chloride is non-toxic, harmless colored, and odorless. It is made up of D-mannitol along with potassium stearate and calcium dihydrogen phosphate, wherein the specific gravity of D-mannitol, potassium stearate and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of the D-mannitoland potassium stearate and calcium dihydrogenphosphate is food grade. Contrary to prior technology this invention offers the advantages of being colourless or slightly white, does NOT alter the whiteness of potassium chloride, is free of cyanide, is safe, and harmless.
4. . The preparation of high-molecular ethylene waterproof membrane made of polypropylene
Polyethylene polypropylene is a brand new substance that has come into use in recent years. Polypropylene is made up of the non-woven polypropylene fabric, as well as polyethylene is the principal raw material. It is composed of anti-aging compounds and blended with high-tech technology, and new technology. The polyester polypropylene water-proof roll material that has an integrated layer is characterized by a high friction coefficient, outstanding stability, high mechanical strength small linear expansion coefficient, a wide temperature adaptability range, exceptional weather resistance, chemical resistance and elasticity. This characteristic makes it an ideal environmentally-friendly protection product for the new century. The procedure for the preparation of the high-molecular polyethylene polypropylene waterproofing membrane consists of the following steps:
Step 1: Measure the raw materials using the following percentages by weight: 80-130 parts of polyethylene resin, 10-20 parts of Talcum powder; 5-10 parts of silica fume. 5-10 parts of glass bead, and 8-16 parts of potassium stearate. 8-18 pieces of carboxylated latex, 10-20 components of anti-aging agents.
Step 2: Mix silica fume, talcum powder the potassium stearate, silica fume and carboxylated styrene-butadiene in a high-speed mixer. Set the temperature to 70-80 deg C, and stir at a high speed for 8 to 18 minutes, and then increase the temperature to 95-100 deg C. Then, glass microbead and polyethylene resin are added, and the mixture is stirred at a rapid rate for 10 to 20 minutes in order to obtain a combination;
Step 3: Put the mix into the feeding space, extrude and form the polypropylene sheet and the plastic sheet entirely using the three-roller machine. Then, connect the guide roller to your tractor, then cut the edges, then move into the coiler to create the finished product.
Compared with the earlier art positive results of the invention are that it creates synergistic effects by in the form of polyethylene resin quartz microbeads potassium stearate, carboxylated butadiene anti-aging agent, latex and subsequent preparation steps. especially when high-speed mixing occurs using a specific order for the input of the raw materials is very important. When combined with the sequence of the invention the performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane exceeds that of traditional waterproofing membranes that are high-performance.
