Q:What's the difference between a macroporous resin and a polyamide resin?
According to its polarity and the selected monomer molecular structure:(1) non-polar macroporous resin, styrene, two vinyl benzene polymer, also known as aromatic adsorbent (such as HPD-100, D-101, etc.)(2) medium polarity macroporous resin polyacrylate polymer, using multifunctional group methacrylate as cross linking agent, also called aliphatic adsorbent(3) polar macroporous resins contain sulfur and oxygen and amide groups, such as acrylamide(4) strongly polar macroporous resins, such as nitrogen oxides, contain nitrogen and oxygen groups
Q:Will the resin work fade?
Fading and yellowing are common problems with all artificial colorants, and the quality of colorants is a little smaller.
Q:Difference between vacuum pouring dry type transformer and epoxy resin casting dry type transformer
First the dry-type transformer is divided into two kinds, one is using epoxy resin transformer coil encapsulation, said encapsulation type dry, one is the paint impregnated insulation coil, called open dry. The two should be carried out under vacuum, when necessary even for coil in a vacuum the container pressure treatment.
Q:Mixed bed resin filling after stratification also need?
Pretreatment of resins1. from the bottom of the exchange column, 3~4m/h 4%HCl solution of two times the resin volume (the total amount of resin of the resin) is taken from the bottom to the bottom, and then soaked with hydrochloric acid solution in the exchange column for 4~8h.2. rinse the resin from top to bottom with clean water until the effluent pH test is about 5.3. the water level placed about 500mm resin layer, from the exchange column into the base tube, at a flow rate of 3~4m/h from the top down into the two times the volume of resin (total amount of cation and anion exchange resin resin) about 4%NaOH solution, and then use the exchange for 4~8h hydrochloric acid solution in the column.4. after alkali soaking, without cleaning, directly for backwashing, backwash start when the velocity is small, when the resin after loosening, gradually increase the backwash flow rate, the expansion rate of the resin layer in 50~70%, maintain 10min, observe whether clear stratification.
Q:How are black spots detected in solid petroleum resins?
The production of two routes with a solid resin with higher molecular weight of DPP and ECH in direct reaction of alkali and molecular weight are regulated by the ratio of two kinds of raw materials; the liquid resin as raw material, in the presence of a catalyst with bisphenol A chain expansion resin with high degree of polymerization, the molecular weight is adjusted by molar ratio the liquid raw material resin and bisphenol A. By using this improved process, the resin grade with higher molecular weight can be directly manufactured. Curing: when using epoxy resin, it is necessary to add a chemical active agent, that is, the curing agent, under appropriate conditions, the linear epoxy resin cross-linking curing into large network molecules, to show its inherent good characteristics.
Q:What's the function of ion exchange resins for water treatment?
It can remove many kinds of ions in water, but it can not remove molecules.
Q:What are the types of chelating resins? What are the exchanged metal ions for each? The more detailed, the better. Which chelating resin is best for lead ion adsorption?
The strong acid cation exchange resin with sulfonic acid groups in the polymer matrix on the structure of crosslinked styrene copolymerization (-SO3H) ion exchange resin in alkaline, neutral, or even acidic medium are shown. This product has the function of ion exchange exchange characteristics of high capacity, fast switching speed, good mechanical strength. The products of the original brand 732#. mainly used for water softening, preparation of pure water, hydrometallurgy, separation of rare elements, antibiotics extraction.
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:What are the properties of petroleum resins and their role in the rubber industry?
The resin and natural rubber particles have good mutual solubility, and have no great influence on the vulcanization process of the rubber. The addition of petroleum resin in the rubber can increase the viscosity, reinforce and soften the rubber. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between colloidal particles, but also improve the adhesion between colloidal particles and tire cord. It is suitable for rubber products such as radial tires.
Q:How can the resin lenses be repaired?
The lenses are worn out and can not be repaired. Usually can pay attention to the maintenance of lenses, can extend the service life.The resin lens is an optical lens with resin as material.
