Q:What are the concepts and differences between thermoplastic resins and thermosetting resins?
Thermoplastic resin: it has the properties of heat softening and cooling hardening, and without chemical reaction, it can keep the performance no matter how many times the heating and cooling are repeated. All thermoplastic resins are linear in their molecular structure.
Q:What's the resin like? Did you buy a money box today?
Someone's glasses are made of resin, and they seem to be broken. Your piggy bank might crack, too.
Q:Wax ribbon, resin ribbon and mixed base ribbon what is the difference?
The most common wax base, generally used for coated paper, with a nail to hang up the font, the price is the cheapest, generally used for resin ribbon tags, PET, PVC label paper, the price is relatively expensive than the other two, out scraping fingers, alcohol wipe off, between, between the two prices for PEV hybrid ribbon PVC, label printing, because the scratch, the price will be cheaper for PET resin, so the label more
Q:What kind of structural adhesive tiles? Epoxy resin structural adhesive (AB) or other?
Hello, you can use HY-127 structure glue, you can, this glue is a single component, and their glue and so on.
Q:Is resin an ester?
Resin: usually refers to the heat after hardening or melting range, softening when there is a tendency to flow under the action of external force, under normal temperature is solid, semi-solid, and sometimes liquid organic polymers. Broadly speaking, any polymer compound that can be used as plastic material for processing raw materials is called resin.
Q:Using unsaturated resin to make glass fiber reinforced plastic products, without adding accelerant, only curing agent, can I? What is the function of accelerant?
The curing reaction of unsaturated polyester resin is free radical polymerization, and its curing agent is actually an initiator, usually organic peroxide.
Q:What is the difference between thermosetting and thermoplastic?
The first heating can soften the flow, heating to a certain temperature, a chemical reaction, a chain solidified and hardened, this change is irreversible, and then again heating, it can no longer soft flow. It is by virtue of this characteristic of molding, the use of the first heating of the plastic flow, under pressure filled cavity, and then solidified into a shape and size of the product. This material is called thermosetting plastic.Thermosetting resins are linear or branched before curing, forming a chemical bond between the molecular chains after curing, becoming a network of three degrees, not only without melting, but also insoluble in solvents. Bakelite, formaldehyde, melamine, formaldehyde, epoxy, unsaturated polyester, silicone and other plastics are thermosetting plastics.
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?
Commonly used are phenolic resins.
Q:How can ion exchange resin be activated?
Cation exchange resin can be activated in vivo. The liquid amount of 2 times the volume of resin. The activation solution with a concentration of 3.0MOL/L hydrochloride, through the resin layer at a flow rate of 1.2-4.0M/H, the volume of 1-2 times, the volume of the resin concentration of 2.0-2.5MOL/L sulfuric acid soaking more than 3H
