Q:The resorcinol resin needs to be mixed with POM powder to produce the last adhesive used to glue the sheet. Usually, how much harmful substance will be produced in industrial production?
Resorcinol formaldehyde resin; formaldehyde and resorcinol polymer 1,3Resorcinol is much more hydroxyl than phenol, so it reacts faster with formaldehyde, even at room temperature.
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:What effect does the resin play on the paint?
There are many kinds of resin, and the resins used in coil coating are acrylic resin, epoxy resin, polyester resin and polyurethane resin. Different tree fat, its physical and chemical properties, as well as weather resistance, corrosion resistance and so on are not the same.
Q:What is the difference between PVC material and resin?
PVC scientific name is polyvinyl chloride, PVC industrial products are generally divided into soft wood and hard wood, such as PVC film, hose, plates, profiles, pipes and so on. The resin is a traditional name, such as plastic resin classification, the PE PVC PP and so on, generally soft PVC film used in the shower curtain, decorative wallpaper, wallpaper, ceiling floor film, film and so on, soft PVC are volatile toxic plasticizer, PE or PU film with non-toxic advice. Hard PVC such as floors, doors and windows and other small pollution, basically negligible, pay attention to ventilation can be.
Q:What are the uses of UV curable resins?
Light green transparent liquid, without adding curing agent and accelerant coating, coated with exhaust billowing coating type construction, into the UV under UV light irradiation of ultraviolet lamp after 3-6 minutes completely cured. After curing, high hardness, simple construction, affordable. Without UV irradiation the glue can be used repeatedly. Suitable for crystal photo frame, paste board, plywood, furniture and other plane surface coating.
Q:What is called regeneration of ion exchange resins?
The regeneration of the resin shall be based on the type and characteristics of the resin, as well as the economy of operation, and the proper regeneration agent and working conditions shall be chosen.
Q:What is the phenolic cloth
3025 phenolic resin pressing material has good chemical resistance and can resist organic solvent, organic acid and rare inorganic acid. It is suitable for many chemical equipment and is not suitable for alkaline medium.
Q:The difference between an epoxy solvent and a non solvent type is that the resin is not the floor
Solvent is usually added to a percentage of the solvent, such as xylene, specifically which is good, and applicable, mainly depends on what you are using, what to do with, if you want to further understand, in contact
Q:What is the principle of exchange of sodium ion resin?
The sodium ion exchange softening treatment is characterized by:(1) to remove the hardness of water, and basicity unchanged, but only Ca2+, Mg2+ and Na+ equal charge molar exchange;(2) the content of Mg2+ in natural water are generally relatively small, mainly exchanged is Ca2+ and Na+, and the molar mass of calcium M (Ca) is 20 M, the molar mass of sodium (Na) is 23, close to, therefore, sodium ion exchange softening water salinity is basically unchanged the water dissolved solids, not much changes;(3) in the regeneration process, sometimes due to wash thoroughly, or leakage of regeneration agent valve system, the water chlorine after softening treatment rather than raw water has increased, but by careful operation can be avoided.
Q:What is resin glass?
It is made of rigid plastic with high transparency: Polystyrene
We are a well-known enterprise specializing in the production and sales of high-grade fiberglass mesh, is a direct supplier for fiberglass mesh. Since the establishment of our company, we have been devoted to setting up a good CIS and completely implementing ISO9001 quality management system.
