How does PAC treat industrial waste water of semiconductor?
Everyone knows that polyaluminium chloride is used to purify sewage, so can polyaluminium chloride treat wastewater generated by the electronic semiconductor industry? How does it treat wastewater generated by the electronic semiconductor industry? The following is a detailed introduction for everyone. I hope it will be helpful to everyone.
The difference between zinc sulfate monohydrate and zinc sulfate heptahydrate
Zinc sulfate monohydrate is easily soluble in water, is not easy to absorb moisture and agglomerate, is easy to store, and is suitable for the feed industry;
Zinc sulfate heptahydrate dissolves in water and is most suitable for foliar fertilizer and other industries with high requirements for water solubility.
Stearic acid is widely used in cosmetics, plastic cold-resistant plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners and pharmaceuticals. and other organic chemicals.
Zinc is a component of more than 40 metal enzymes in animals, an activating factor of more than 200 enzymes, and participates in nucleic acid and protein composition, energy metabolism, oxidation reduction, cellular immunity and humoral immunity.
What important role does zinc oxide play in rubber ?
Zinc oxide is used as an activator, vulcanization accelerator and reinforcing agent in synthetic rubber, and has a coloring effect, which can promote the vulcanization, activation, reinforcing and anti-aging effects of rubber, strengthen the vulcanization process, and improve the quality of rubber products and Tear and abrasion resistance.
The above is about the important role that zinc oxide p
Zinc fatty acid is a white powder, insoluble in water. Zinc stearate is mainly used as a lubricant and release agent for styrene resin, phenolic resin, and amine resin. At the same time, it also has the functions of vulcanization activator and softener in rubber.
Sodium Hexametaphosphate is a white powder, easily soluble in water, insoluble in organic solvents, highly hygroscopic, and gradually absorbs water in the air to become sticky. It can form soluble chelates with metal ions such as Ca, Ba, Mg, Cu, and Fe. It is an excellent water quality treatment agent.
PAC, divided into high viscosity (HV) and low viscosity (LV), can be used as thickener, rheology control agent, adhesive, stabilizer, protective colloid, suspending agent and water retaining agent; in the oil mining industry Among them, PAC is a better drilling mud treatment agent and material for preparing completion fluids. It has high mud-making rate and good salt and calcium resistance. For fr
Potassium Silicate Characteristics Used In Inorganic Coatings
With the development of the coatings market, ecology and green have gradually become industry trends. Inorganic coatings need to be used in conjunction with potassium silicate materials to ensure their environmental protection, breathability, moisture-proof, durable, mildew-proof, flame-retardant and other properties. Let's talk about the three characteristics of potassium silicate in the use of i
