Q:What are the specific properties of building resin materials or building resin boards?
Although many members of the resin family, but not any kind of resin can be used on the building. Widely used in construction of the resin material: Polycarbonate (polycarbonate resin), Acrylic (polymethyl methacrylate resin, commonly known as acrylic), Copolyester (copolyester resin), epoxy resin, acrylic resin and so on. The resin material is usually in manufacturing form application of sheet to construction, also colloquially known as resin plate or cover plate and building (named for the German GAINKER cover Ke company as the world's first comprehensive comprehensive building resin plate solutions innovator).
Q:Why is weak resin relatively easy to regenerate?
The resin used for a period of time after ion exchange, adsorption of impurities is close to saturation, must carry on the regeneration treatment, chemical agent ion adsorption resin and other impurities was removed, so as to restore the original composition and performance. In practice, in order to reduce the cost of regeneration, it is necessary to appropriately control the dosage of regeneration agent, so that the performance of the resin can be restored to the most economical and reasonable regeneration level, and the recovery degree of the control performance is usually from 70 to 80%. If higher levels of regeneration are achieved, the regeneration dose will increase considerably, and the utilization of the recycled agent will decrease.The regeneration of the resin shall be based on the kind and characteristics of the resin, as well as the economy of the operation, and the proper regeneration agent and working conditions shall be chosen.The regeneration characteristics of resin are closely related to its type and structure. The regeneration of strong acid and strong alkaline resin is difficult. The regeneration dose is much higher than the theoretical value, while the weak acid or weak base resin is easy to regenerate, and the regeneration dose needs only a little more than the theoretical value. In addition, resins with large pass and low cross linking degree are easy to regenerate, while those with gel type and high crosslinking degree have longer regeneration reaction time.
Q:Please heroes, PCB board and jack jack electroplating resin what is the difference?
The oxidation resistance of the plating is good, but the process requirements are high, the price is expensive, and the resin is well insulated
Q:What is the resin exactly?
Classification of resinsAccording to resin synthesis reaction classification, according to resin molecular backbone composition classification1. classification by resin synthesisAccording to this method, resins can be divided into polymers and condensation polymers. Polymers are polymers made by addition polymerization, and their chain structures are chemically identical to those of monomers, such as polyethylene, polystyrene, and polytetrafluoroethylene.Condensation polymer is a polymer prepared by condensation polymerization. Its structural unit is chemically different from that of monomer, such as phenolic resin, polyester resin, polyamide resin and so on.2., according to resin molecular backbone classificationAccording to this method, resins can be classified into carbon chain polymers, hetero chain polymers, and elemental organic polymers.A carbon chain polymer is a polymer composed of carbon atoms of the backbone, such as polyethylene, polystyrene, etc..A chain polymer is a polymer consisting of atoms of two or more elements, such as carbon, oxygen, nitrogen, sulfur, etc., such as POM, polyamide, polysulfone and polyether. Organic polymer refers to the main chain does not necessarily contain carbon atoms, mainly by silicon, oxygen, aluminum, titanium, boron, sulfur, phosphorus and other elements of the atoms, such as organic silicon.
Q:How many kinds of epoxy resin are there?What are the characteristics of each?
This kind of alicyclic epoxy resin epoxy resin is cyclic olefin by grease prepared by epoxidation of double bond, their molecular structure and two phenol propane epoxy resin and epoxy resin have very big difference, the former is directly connected to the lipid epoxy ring, epoxy and the latter is connected in the benzene nucleus or aliphatic hydrocarbon with epoxy propyl ether. Alicyclic epoxy resin cured group has the following characteristics: compression and tensile strength were higher; the long run the storm can still maintain good mechanical properties at high temperature; the arc resistance, UV resistance and ageing resistance and weather resistance is good.
Q:What is the difference between acrylic and resin?
Acrylic: name of polymethyl methacrylate (PMMA), we often say is organic glass. Good transparency and high hardness. It's a kind of plastic.
Q:How much can the epoxy resin floor be able to bear?
1.0mm thin epoxy floor coating: epoxy floor coating thin construction scheme can bear load performance of 1-2 tons, impact resistance, wear resistance, it is mainly for decoration such as: the office does not require transport, no mechanical equipment area, concrete foundation ground flatness, good strength, can choose a at the end of a two coating putty two surface thin epoxy floor coating process.Terrazzo, emery, ceramic tile foundation, as long as the decorative effect can be used: one bottom, two sides of the simple process. Concrete foundation ground strength, roughness is very poor situation, it is recommended to do a layer of cement leveling layer or self leveling cement leveling layer, and then laying epoxy thin coating floor process.
Q:Make leather shoes, polyurethane resin glue
You're not very specific,If you need to make leather shoes, then you only need to go to the corresponding resin manufacturers, you can get the corresponding molding method.
Q:What is called regeneration of ion exchange resins?
The regeneration characteristics of resin are closely related to its type and structure. The regeneration of strong acid and strong alkaline resin is difficult. The regeneration dose is much higher than the theoretical value, while the weak acid or weak base resin is easy to regenerate, and the regeneration dose needs only a little more than the theoretical value. In addition, resins with large pass and low cross linking degree are easy to regenerate, while those with gel type and high crosslinking degree have longer regeneration reaction time.The type of recycling agent should be selected according to the ion type of resin, and appropriate choice of lower prices of acids, bases or salts. For example: sodium type strong acid cation resin can be used to regenerate the 10%NaCl solution, 2 times of dosage for its exchange capacity (NaCl 117g/ l resin); hydrogen type strong acidic resin with strong acid regeneration, reaction with sulfuric acid to produce calcium sulfate precipitate with calcium sulfate to prevent by resin adsorption. For this reason, it is better to pass through the dilute sulfuric acid regeneration of 1 ~ 2%.
Q:How high is the melting point of resin?
The performance of epoxy resin is determined by the average molecular weight and molecular weight distribution and chemical properties (epoxy content, hydroxyl content, heterogeneous end group structure and content), physical properties (viscosity, softening point, solubility etc.) to determine the. A small amount of impurities (water, NaCl, free phenol, solvent, epoxy chloropropane, high boiling agent, etc.) also have a great influence on the quality of the resin.
