Products

ZGER8420Polishing resin
"争光" brand ZGER8420 is a mixed bed resin composed of gel-type electronic grade cation resin and electronic grade anion resin. It is suitable for the preparation and finishing of ultrapure water in the electronics industry. It can produce resistivity greater than 15MΩ·cm. High purity silicon-free desalinated water with high exchange capacity and excellent penetration resistance.
ZGD851 copper nickel recycled resin
"争光" brand D851 is a chelate resin with a weakly acidic imine diacetate [-CH2N-(CH2OOH)2] on a special macroporous structure of styrene-divinylbenzene copolymer. The product is capable of immobilizing and kneading one or more specific cations over a wide range, even from high concentrations of solution. It is mainly used for the separation and purification of high-valent metal ions and transition elements. It is especially suitable for the alkaline production process of ion-exchange membrane. The brine is re-refined when the content of strontium in brine is close to or higher than that of calcium. It has high calcium and magnesium. Selective and have a high exchange capacity.
ZGD840 colloidal palladium recovery resin
"争光" brand D840 is a chelate resin with a weakly acidic thiourea group (-CH2-S-C-NHNH2) on a styrene-divinylbenzene copolymer having a special macroporous structure. The product is capable of immobilizing and kneading one or more specific cations over a wide range, even from high concentrations of solution. It is mainly used for separation and purification of free mercury and precious metals, with uniform particles and good mechanical strength.
ZGNH001 removal of ammonia nitrogen resin
ZG NH001 is a dark black demineralized ammonium ion exchange resin with a strong group and a high degree of crosslinking on a crosslinked styrene-divinylbenzene copolymer. It is mainly used for the removal and recovery of ammonium ions in wastewater treatment. It has good mechanical strength, high exchange capacity and strong polarity. It is especially suitable for low ammonium content, but requires high recovery rate, low leakage and discharge. Standard wastewater.
ZGD890 denitrate nitrogen resin
"争光" brand D890 is an anion exchange resin with a quaternary ammonium group [-N(CH3)3OH] on a macroporous structure of styrene-divinylbenzene copolymer. This product is mainly used for the removal of nitrate and nitrite in tap water and drinking water, and has excellent selectivity to nitrate. It can also be used in sugar industry, its strong alkaline exchange group and macroporous structure, sugar The pigments and impurities in the liquid have a good adsorption effect.
ZGA304 gold palladium silver iridium recycled resin
"争光" brand ZGA304 exchange resin is mainly used for the adsorption and recovery of precious metals such as gold and silver in cyanide-containing wastewater, biochemical products, radioactive elements and the extraction of tungsten and molybdenum in hydrometallurgy.
ZGS820 arsenic resin
"争光" brand ZG S 820 is a special resin, which is a high-molecular polymer with active iron groups and surface heat treatment on a styrene-divinylbenzene skeleton with a macroporous structure. This chemical structure helps to form a stable complex with arsenate ions in the water, so as to remove and reduce the concentration of arsenic in drinking water, which meets the national sanitary standard for drinking water, that is, below 10 μg/L.
ZG S 820 resin has a high adsorption capacity and a fast adsorption rate for arsenate ions. When the arsenic is removed by the resin, the arsenic removal rate of the solution is high, the arsenic content in the arsenic removal solution is completely up to standard, and the ion exchange column is washed with sodium hydroxide as an eluent to completely recover As(III) and recycle the resin. .
ZGF860 defluorination resin
"争光" brand ZG F 860 is a special resin, which is a high-molecular polymer with active aluminum groups and surface heat treatment on a styrene-divinylbenzene skeleton with a macroporous structure. This chemical structure helps to form a stable complex with the fluoride ion in the water, so as to remove and reduce the fluorine concentration in drinking water, which meets the national sanitary standard for drinking water, that is, less than 1 mg/L.
ZG F 860 resin can be used as a defluorination agent alone as a filler for defluorination filters, and is directly used for fluoride removal in domestic drinking water. It can also be mixed with other filter materials (such as activated carbon) or drinking water resin according to the specific requirements of users.
SD300 large hole decolorizing resin
"争光" brand SD300 is a kind of aromatic macroporous adsorption resin of styrene skeleton, which can separate and adsorb non-polar substances in polar solution, and decolorize and purify wastewater produced by food and beverage industry.
SD500 macroporous adsorption resin
"争光" brand SD500 is an anion exchange resin having a quaternary ammonium group [-N+(R3)] on the acrylic skeleton of the macroporous structure. The special macroporous structure and acrylic skeleton of the product have good hydrophobicity, promote the adsorption and analysis of organic matter, and make the resin have excellent anti-pollution performance and stable physical properties. It is especially suitable for decolorization of beverages, sugar liquids (especially sucrose), decolorization of organic solvents such as glycerin and amino acids, and also as an organic cleaning agent.
"争光" brand SD500 resin will not release any harmful substances during use, will not change the taste and quality of the beverage, and will not cause harm to the food. After removing the polymer hydrophilic anionic organic substance and the pigment in the sugar liquid, it is easy to recover the exchange ability by regenerating with a neutral or alkaline sodium chloride solution.
