What is Potassium Stearate ?
Potassium is also known in the form of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in chloroform, ether and carbon disulfide. The solution that is aqueous is alkaline in comparison to phenolphthalein or litmus and the ethanol solution is slightly alkaline to phenolphthalein. It is made by neutralizing the reaction of stearic Acid with potassium hydroxide. It is often used in manufacturing detergents, surfactants and softeners. It is also utilized in the fabrication of anti-slip adhesives, graphene modified glues also known as anti-caking substances, as well as waterproof coils.
1. . It is used to create a brand new type of slip-resistant material
The non-slip new material comes with solid wear resistance, as well as anti-slip performance. Furthermore, the raw ingredients used in the formulation are easily available for purchase. When it comes to manufacturing, the process is easy and user-friendly, and the manufacturer offers the largest and most convenient formula. Production materials include: short fiber, water-based glue, Zinc Oxide, Anti-Aging agent photositiator, stearic, Potassium thermo-stearate, potassium stearate or coupling agent, and carbon fiber. Based on the mass percentage, this new non-slip materials includes 5-10 parts of the very short fibers 0.5-5 components of water-based glue. 3-7 bits zinc oxide one to five pieces of antioxidant, 2-8 slices of acids 1-5 components of photoinitiator Potassium Stearate 10-13 parts 1-8 parts in potassium stearate, 3- 10 parts coupling agent in addition to 0.5-10 pieces of carbon fiber.
2. . used to prepare graphene-modified glue
Graphene is incorporated into the existing glue to modify the high-temperature resistance of the cement and 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 in the following order:
Level 1, the graphene is mixed with n-butanol and toluene, ultrasonic dispersion is uniform, in order 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 ceases, and the temperature is reduced to around 80 degrees Celsius. ethylenediamine gets added to the reactor, stirring it evenly for a few minutes, then allowed to sit for one day before obtaining graphene-modified adhesive.
3. Preparation and formulation of composite anti-caking agents to be used in food-grade potassium chloride
In order to lessen the risk of excessive blood pressure it is currently permitted to add a little of potassium chloride to replace sodium chloride that is present in the salt. In the process of transportation and storage of potassium chloride in the salt promotes breakdown and recrystallization on the powder surface, thereby forming one of the crystal bridges that are formed in those pores in the powder and crystals are then bonded with each other over time to develop. Huge mass. The weakening in fluidity can affect its use in table salt. Thus, to prevent agglomeration, it is important to add a sufficient amount of anti-caking agent in the production process.
The anti-caking agent that is a composite in food-grade potassium chloride is safe, harmless non-toxic, colorless, and odorless. It is comprised of D-mannitol also known as potassium stearate. It is calcium dihydrogen phosphate, wherein the particular gravity of D'mannitol potassium stearate, and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of the D-mannitol, potassium stearate and calcium dihydrogen is food grade. When compared with prior art the invention has benefits of being colorless and slightly white, and does not alter the hue of the potassium chloride and does not contain the cyanide element, is non-toxic and safe.
4. . The preparation of high-molecular ethylene the waterproof membrane is made of polypropylene
Polyethylene polypropylene (PPE) is a relatively new material used in recent years. Polypropylene is made up of polypropylene non-woven fabrics and polyethylene is the principal raw material. It is made from anti-aging chemicals and compounded by high-tech, new technological advancements and new technologies. The polymer polyethylene and polypropylene composite waterproof roll material with an integrated coating has a huge friction coefficient, exceptional quality, durability Small linear expansion coefficient, a wide temperature range of temperature adaptation, superb chemical resistance, weather resistance, and flexibility. It is a great sustainable product for protecting the environment in the current century. The procedure of making the high-molecular polyethylene polypropylene waterproofing membrane is as follows:
Step 1: Weigh the raw materials using the following weight percentages: 80-130 parts of polyethylene resin. Also, 10-20 percent of talcum powder, 5-10 parts of silica fume, 5-10 pieces made of glass, as well as 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated styrene-butadiene latex, 10-20 pieces of anti-aging agents.
Step 2: Pour silica fume, talcum powder silica fume, potassium stearate, and carboxylated styrene-butadiene latex into a high-speed mixer. Adjust the temperature to 70 to 80 deg C, then stir it at high speed for around 8 to 18 minutes and then increase the temperature until it reaches 95-100 degrees C. After that, a glass microbead and polyethylene resin are added, and the mixture is stirred at high rate for 10 to 20 minutes in order until you get a perfect mixture.
Step 3: Put the mixture into the feeding zone create the extrusion and Polypropylene sheet, as well as the plastic sheet entirely using the three-roller machine. After that, you can pass an intermediate roller to the tractor, trim the edges, then enter it into the coiler, forming the final product.
Comparing to standard of the art advantageous effects of this invention include: synergistic effect by materials such as polyethylene resin silica fumes, glass microbeads, potassium stearate, carboxylated butadiene latex, anti-aging agents, and the subsequent steps to prepare, especially when mixing at high speed is done using a specific order for the input of the raw materials is particularly vital. In combination with the sequence used in the present invention it is evident that the performance of the produced high-molecular Polyethylene polypropylene waterproofing membrane surpasses the traditional high-performance waterproofing membrane.
