FAQ
- Use of sealant
- 0 ° C or more, ± 12.5% of the average width of the joint at the time of sealing, 0 ° C or less, the total amount of ± 5% of the average width of the joint
- Plastic (PVC) special waterproof adhesive properties and enhance the performance of what attention
- Must be painted heavier than the normal paste;
- What is the principle and amount of amine chloride used as a binder?
- Epoxy resin and polyurethane glue which one is better
- Zhuang Code paint is China's top ten paint brand? I would like to know how to see ah, the main oneself want to develop in this area, because not very knowledgeable, ask you heroes
- Online search out of a ah, personally feel that the paint is still less with some of the better, after all, the nature of things generally contain bad material for the body, or less used as well. If it is decoration, then recommended wallpaper, the elephant, Ruibao, Ouya such a wallpaper are good, safe and environmentally friendly, the landlord can go to the local building materials market to see.
- The market characteristics of adhesives
- Analysis of China's adhesive products industry can be seen, the development of China's adhesive industry started relatively early, with the economic development and industry's own pioneering and innovative, China's adhesive industry, the growth rate gradually accelerated. The scope of application is extended to the fields of construction, automobile, electronics, household appliances, carpentry, housing equipment, paper products and packaging, footwear, transportation, aerospace and medical and health fields, which are engaged in the production and research of adhesives. As China's adhesive products market continues to expand, many foreign companies and Hong Kong and Taiwan manufacturers optimistic about the huge market in mainland China, have to invest in China, the establishment of wholly-owned and joint ventures.
- My company wants a one-component anaerobic adhesive / sealant, which is good on the market? Who told me the sound.
- Friends, you say this is very general ah A single component of the market anaerobic adhesive / sealant, a lot of companies selling glue have, you used to use the original Dole or Loctite, or Dow Corning's it? In fact, these are very good ah OKorder Daoer is not a one-component anaerobic adhesive / sealant, can be fast curing at room temperature. After curing, into a shock-resistant leakage, corrosive liquid leakage and air leakage of high cross-linked thermosetting plastic. You go there to see it
- Will the kind of adhesive soluble in water (preferably powder), melting temperature of about 800 degrees, was neutral or weak alkaline, thank you!
- Alginate is slightly soluble in water and insoluble in most organic solvents. It is dissolved in alkaline solution, so that the solution is viscous. Sodium alginate alginate is hygroscopic and the amount of moisture contained in the equilibrium depends on the relative humidity. The dried sodium alginate is stored fairly stable in a well-sealed container at 25 ° C and below. Sodium alginate solution is stable at pH 5 to 9. The degree of polymerization (DP) and the molecular weight are directly related to the viscosity of the sodium alginate solution, and the decrease in viscosity during storage can be used to estimate the degree of sodium alginate de-polymerization. High degree of polymerization of sodium alginate stability is less than the degree of polymerization of sodium alginate. It is reported that sodium alginate can be catalyzed by proton hydrolysis, which depends on time, pH and temperature. The propylene glycol alginate solution is stable at room temperature at pH 3 to 4; when the pH is less than 2 or greater than 6, the viscosity will decrease even at room temperature. The sodium powder is wet with water and the hydration of the particles makes the surface sticky. The particles are then quickly bonded together to form clumps, and the agglomerates are slowly and completely hydrated and dissolved. Alginate is more difficult to dissolve in water if it contains other compounds that compete with alginate for hydration. Water in the sugar, starch or protein will reduce the rate of sodium alginate hydration, mixing time necessary to extend. A monovalent cation (such as NaCl) also has a similar effect at concentrations above 0.5%. The pH of sodium alginate in 1% distilled water was about 7.2....
- Preparation of white latex formula and production process
- Do not brush latex paint called scraping in the industry can not be on the Daya Hall, that is, the putty itself, a large amount of glue, naturally there is no powder problem!
