Q:What is resin chemistry?
Resin chemical is related to the chemical resin baaNot a plastic resin, the resin is heated usually a softening or melting range, softening tendency to flow under the external force, room temperature is solid, semi-solid, sometimes can be a liquid organic polymer. Broadly speaking, any polymer can be used as raw materials for plastic products are called resins.Resin and synthetic resinnatural resin of the points. The natural resin is amorphous organic matter from the secretions of plants and animals in nature, such as rosin, shellac, amber. Synthetic resin is chemically synthesized from simple organic compounds or some natural products obtained by chemical reaction of the resin product.Purpose: food grade industrial grade; grade; analysis; nuclear grade resin; double bed; high velocity with mixed bed resin; and the filter cover resin with moving bed.
Q:Why is weak resin relatively easy to regenerate?
Special regeneration treatmentThe resin with serious pollution, acid or alkaline salt solution such as repeated treatment with 10%NaCl alkali salt solution +1%NaOH dissolved organic matter, and 4%HCl or 10%NaOH were used and 1%HCl dissolved inorganic compounds, followed by 10%NaCl +1%NaOH, at about 70 DEG C.If the above treatment does not meet the requirements, the oxidation process can be used. After washing the resin with water, the sodium hypochlorite solution with a concentration of 0.5% is used to control the flow rate from 2 to 4BV/h, and the amount is 10 to 20BV. Then the water is washed by water and treated with salt water. It should be noted that oxidation treatment may lead to the bonding of macromolecules in the resin structure, resulting in degradation of the resin, swelling degree, easy to crack, so it is not suitable for use. 50 cycles are usually used before an oxidation treatment takes place. Because of the strong oxidation resistance of the chlorinated resin, the resin is treated with brine before it is oxidized and changed into chlorine, which can avoid the change of pH value in the treatment process and make the oxidation more stable.
Q:How many kilograms of 1 cubic meter epoxy resin mortar?
It should be 2100~2200 kilograms. According to the cement, sand, mortar admixture in different proportion, mortar density is different, without considering the gas under the condition of normal mortar is 2100~2200KG/m3, the proportion of pure epoxy resin is slightly larger than the water, at about 1100kg/m3, the mortar density had little effect, so the calculation, a cubic epoxy resin mortar should be 2100~2200 kg.
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:Why pretreatment of resins?
The new resin must be pretreated before it is sent to the exchanger. This is because a small amount of no low polymer polymerization good and did not participate in the polymerization reaction substance containing the new resin, when the resin with water, acid, alkali or other contact solution, the material will be transferred to the influence of water quality in the solution, in addition to the organic matter, may also contain iron, copper and lead. Inorganic impurities, so the new resin should be pretreated before use to remove soluble impurities in resin. At the same time, pretreatment can not only improve the stability of resin, but also play a role in activating resin and improving its exchange capacity.
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:What is resin? What's it for?
Natural resin is a very high value of physiotherapy, but very difficult to use it, because they are very thick and sticky. So in aromatherapy, we will use solvent or alcohol to natural resin processed into the liquid resin can be used.The resin can not only protect and closed their wounds, and many other magical. Such as spices, used as medicine and processing of resin paint and so on. In medicine is a treasure, it can reconcile the five internal organs, the belly of the disease. Remove the root, leaf and fruit of Liquidambar tree can also be used as medicine, can pass through the wind. Arm.
Q:What's the advantage of making epoxy flooring?
Epoxy resin flooring range of use is:Cement, terrazzo flooring, such as chemicals, electronics, machinery, food, medicine, chemicals, tobacco, beverages, textiles, clothing, furniture, plastics, stationery and sporting goods, etc..
Q:What is the principle of exchange of sodium ion resin?
The sodium ion exchange principle is the atomic softening treatment by sodium cation exchange resin, so that the water hardness components Ca2+, Mg2+ and Na+ in resin exchange, and adsorption of Ca2+, Mg2+, the water softening. For example, "RNa" stands for sodium type resin and its exchange process is as follows:2RNa+ Ca2+==R2Ca+2Na+2RNa+ Mg2+==R2 Mg+2Na+That is, the water passes through the sodium ion exchanger, and the Ca2+ and Mg2+ in the water are replaced by Na+. After a primary Na+ exchange, the residual hardness of water is generally less than 1.5 * 10-2mmol/L, which can be used for low pressure boilers.
Q:Is novolac epoxy resin or epoxy resin?
The novolac epoxy resin prepared by epoxidation with linear phenolic resin has the high thermal stability and the main reactivity of the epoxy resinTherefore, it can be said that the epoxy resin is modified by epoxy group
