Q:What are the concepts and differences between thermoplastic resins and thermosetting resins?
Thermosetting resins undergo chemical changes after heating, which gradually hardens and hardens without being softened by heat.
Q:What are the specific properties of building resin materials or building resin boards?
The performance of each building resin material is not the same, such as some resin is rich in color, some resin very resistant to impact, very good at doing some resin molding, some special surface resin material has high fireproof grade, this leads to the need to according to the requirements of building the application of different, choose the right resin solution.
Q:What kind of structural adhesive tiles? Epoxy resin structural adhesive (AB) or other?
Recommend the use of the latest new product ceramic tile glue, with the highest grade of tough ceramic tile glue can be used.
Q:What is the resin in the water purifier?
Resins refer to ion exchange resins
Q:Corrosion resistance of epoxy resinHow many pH value acids and bases are there?Is it antiseptic to use epoxy resin to resist water?
10% liquid, 100 degrees, can guarantee a month without damage.
Q:How many years can the resin handicraft be kept? How to save? Thank you
It can be kept for 10-15 years.
Q:Is novolac epoxy resin or epoxy resin?
General bisphenol A epoxy resin can be cured at normal atmospheric temperature, small volume shrinkage, acid and alkali resistance, but poor thermal stability
Q:Which trees can produce resin?
Resin is a plastic product, not a knot on a tree.
Q:What is the chemical name of the resin?
Rosin, benzoin is a natural resin, phenolic resin, polyvinyl chloride resin, synthetic resin.
Q:What is the national standard for the exchange capacity of cation exchange resins?
Generally, according to 900-1000mmol/L, there may be some users who have some difficulty understanding this "mole equivalent". Here's an example of softened water:Suppose the raw water hardness (as in calcium carbonate) is: 300 mg/LCation exchange resin exchange capacity: 900mmol/L
