Dye Intermediates, also known as intermediates, generally refer to various aromatic hydrocarbon derivatives used in the production of dyes and organic pigments. They are based on aromatic hydrocarbons such as benzene, toluene, naphthalene and anthracene from coal chemical and petrochemicals, and are produced through a series of organic synthesis unit processes (see reaction process). With the development of the chemical industry, the application range of dye intermediates has been extended to...
The flocculant is a newer product modified by polyacrylamide. Its characteristic is that it has strong ionized quaternary ammonium salt group and tertiary ammonium salt group on the macromolecular chain, and its molecular weight is up to 15 million. Therefore, compared with the traditional MANNICH modified products, it is applicable to a wider range of pH values, higher charge stability, large floc formation, and greatly increased settling velocity. Moreover, the use of a small amount of water...
Everyone found that their clothes or household fabrics may be contaminated with some fuel or other colors. Therefore, many times we need to use some bleaching products. However, many people do not know 84 disinfectant. How to use the best, then Xiaobian will introduce the use of disinfectant for everyone. First, the user must wear gloves before starting to use the disinfectant. Because 84 disinfectant is very corrosive and irritating, if you do not use gloves to block the contact between the...
Water Treatment flocculants are divided into inorganic and organic types according to their molecular composition. The application of inorganic flocculants has a long history, but its application has been limited due to large quantities and low efficiency. In organic polymer flocculants, the application of synthetic organic polymer flocculants is also limited due to the high production cost and the presence of a certain amount of residual monomers, which inevitably brings about toxicity. The...
For Polylactic Acid Fiber applications,it belongs to one of the Bio-based Materials.Polylactic acid fiber is a fully Biodegradable synthetic fiber that can be obtained from cereals. After the product is discarded, it can be decomposed into carbon dioxide and water through the action of microorganisms in soil or seawater. When burning, it will not emit poison gas and will not cause pollution. It is a sustainable ecological fiber. What is Polylactic acid fiber What is polylactic acid fiber? For...
1.Petrochemical is a major supplier of energy Petrochemicals mainly refer to petrol, kerosene, diesel oil, heavy oil, and natural gas produced by petroleum refining and are currently the main suppliers of major energy sources. In 1995, China produced 80 million tons of fuel oil. At present, the world’s oil and natural gas consumption accounts for about 60% of the total energy consumption; China’s consumption of coal is less than 20% due to its large use of coal. The energy provided by...
A turtle, because the shell is entangled in a plastic bag when it is small, when it grows up, the entanglement divides the whole turtle shell into two distinct parts, like a tight hoop. The hazards and threats brought by plastic products are more than sea turtles. The plastic white pollution that can be seen everywhere in our lives is also affecting our beautiful life. The development of bio-based degradable materials not only can fundamentally solve the problem of white pollution, but also...
PS Plastic Name: Polystyrene PS Plastic Properties Specific Gravity: 1.05 g / cm 3 Molding Shrinkage: 0.6-0.8% Molding Temperature: 170-250 ° C Introduction of PS Plastic Polystyrene (PS) plastic is one of the older Plastics And Products, along with Polyethylene, Polyphenylene Sulfide, and other Plastic Additives, production processes have also been relatively complete. Compared with other plastics, PS has the characteristics of good transparency (light transmittance of 88%-92%) and surface...
Vinyl acetate is polymerized to form polyvinyl acetate. The Polymers can be saponified to give various grades of flocculent, flake, granular, and powdery polyvinyl alcohol with 99.9% and 88% alcohol solvency under different amounts of alkali. The polyvinyl alcohol solution has good film-forming properties. Emulsification. Polyvinyl alcohol is mainly used for the production of synthetic fibers, plastics, adhesives, coatings, new building materials, etc., and is widely used in the chemical...
Silicone builders are a class of silicone surfactants that are often used as spray aids for pesticides.Silicone builders are among Catalysts And Auxiliaries.Compared with other spray auxiliaries such as spray dried Polymeric Aluminium Chloride（It also can be used as a Flocculant）,silicone auxiliaries have the following remarkable features in addition to the ability to increase the wetting, spreading and adhesion of the liquid: First, the surface tension of the liquid can be lowered to a lower...
