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 is the coated sand in casting? What's the relationship between it and the resin?
The coated sand is a kind of casting material, can be used to shape, playing sand, divided into the use of cast iron, cast aluminum and copper is different, you can go to the specific reference to see it, too much, I also said not specific
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?
Its promoter is cobalt water (cobalt cobalt cobalt solution), its role is to promote the curing reaction (to speed up the reaction). Without accelerators, the cure rate is only a little slower.
Q:How do you make resin powder?
Application of high polymerization degree PVC resin in cable materialThe property of high degree of polymerization PVC resin, because of its special structure, PVC resin has excellent resistanceFlammability, mechanical properties, and good electrical properties.And the high degree of polymerization PVC resin, because its molecular weight is much higher than ordinary polyvinyl chloride resin, molecular chainObvious growth, so compared with ordinary PVC resin, but also has the following characteristics:(1) higher heat resistance.(2) better cold resistance.(3) higher mechanical properties.(4) smaller thermal deformation.(5) better flexibility and elasticity.In the application of cable material, because of the high degree of polymerization, PVC resin has the above characteristics, you can use it to produceCable for various special purposes.Heat resistant cable insulation and sheath material, with the increase of polymerization degree, PVC resin heat resistance liftingHigh mechanical properties are also improved. It will be the ideal raw material for the production of heat-resistant PVC cable material.At present, high degree of polymerization PVC resin is used to produce high temperature resistant cable material in ChinaDegree of production of S G-2 PVC resin.
Q:How to maintain the resin lens?
1, resin and glass lenses are coated with a layer of MgF2, its hardness is relatively high, not only has the antireflection effect, to a certain extent also anti abrasion;2, of course the best use of lens paper wiping glasses, is the kind of paper to wipe the microscope lens, even the best tissue as the (each of the approximately two or three yuan), but usually with lens cleaning cloth is the most convenient, they so can also do not advocate, wipe with a handkerchief and other items, as they are all cotton fabrics;
Q:What's the difference between resin clay and super light clay? I'm a newbie. I want to make my own hand puppet. That will work better
Making effect, ultra light soil stuff to do a sponge, not bright, do you spend as the simulation effect resin clay, clay resin can be very thin are not broken cracks, do have toughness, now do resin clay flower simulation is the highest degree.
Q:I would like to ask accessories for the use of diamonds, resin drilling, acrylic drill in the end how to distinguish? Are they different in price?
Judging from the temperature resistance, the diamond is also the best. It can be used for electroplating welding, temperature resistance, but usually only for acrylic resin and drill decoration. Separate glass drilling, drilling acrylic resin and drill, then the lighter to burn, burning glass is lack of time not burning, burning acrylic diamond will has a thick plastic taste, and resin drilling during combustion it will release a faint smell of turpentine
Q:What is bakelite?
The phenolic resin is of great polarity and has good adhesion to metals and most non metals, and the adhesive strength is higher. Due to the existence of a large number of benzene rings in phenolic resins, they can be cross-linked into a body structure, which has higher rigidity, high heat resistance, creep resistance, ablation resistance and good dimensional stability.
Q:What's the function of ion exchange resins for water treatment?
In the field of water treatment, the demand for ion exchange resin is very large. It accounts for about 90% of the total output of ion exchange resin, and is used for the removal of various anions and cations in water. At present, the maximum consumption of ion exchange resin is used in the pure water treatment of thermal power plants, followed by atomic energy, semiconductor, electronic industry and so on.
Q:What are the basic types of synthetic resin tiles?
Thermoplastic resins can be rapidly molded and can be molded repeatedly. Solid polymer type structure is thermosetting resin, containing multifunctional molecules in the molecular chain, the curing agent and the heat and pressure under the effect of softening (or melting) and curing (or aging) become insoluble, infusible polymers. The typical thermosetting resin general with phenol formaldehyde resin (commonly known as phenolic resin), urea formaldehyde resin (commonly known as urea formaldehyde resin, melamine formaldehyde resin) (melamine formaldehyde resin), epoxy resin, unsaturated polyester resin, polyurethane, etc..
