Exhaust gas treatment is generally divided into organic waste gas (VOCs class exhaust and organic compounds) and inorganic waste gas treatment, odor odor elimination. 1, organic waste gas The following options should be considered for the treatment of organic waste gas: the type and concentration of organic pollutants, the exhaust gas temperature and the discharge flow rate of the organic waste gas, the particulate matter content, and the level of pollutant control required. Special care must be taken when organic exhaust contains high concentrations of substances that convert organic acids, such as chlorine, fluorine, sulfur and halogens. They can cause serious corrosion or catalyst poisoning to the equipment. Organic waste gas treatment composition Organic waste gas treatment refers to the process of adsorption, filtration and purification of organic waste gas generated in industrial processes. Organic waste mainly includes various kinds of hydrocarbons, alcohols, aldehydes, acids, ketones and amines. Organic waste gas treatment is usually organic waste gas treatment of formaldehyde, benzene xylene and other benzene organic waste gas treatment, acetone butanone organic waste gas treatment, ethyl acetate waste gas treatment, oil mist organic waste gas treatment, furfural organic waste gas treatment, styrene, acrylic acid Organic waste gas treatment, resin organic waste gas treatment, additives, organic waste gas treatment, paint mist organic waste gas treatment, days that water organic waste gas treatment and other organic matter containing oxygen and air purification. Organic waste gas treatment features Organic waste gas main features: Organic waste gas is usually easy to burn, easy to explode, toxic, can not be dissolved in water, can be dissolved in organic solvents inside, dealing with a greater degree of difficulty characteristics. Organic waste gas treatment methods introduced: At present, the process of organic waste gas treatment, the most commonly used method is the organic waste gas activated carbon adsorption treatment, catalytic combustion, catalytic oxidation, acid-base neutralization, plasma treatment Law and many other different principles and methods. However, there is a problem of high-pressure discharge in the plasma treatment method at present, and the danger of explosion is prone to occur. The post-treatment cost of activated carbon is also high. 2, inorganic waste gas Inorganic exhaust composition According to their characteristics, inorganic waste gas is divided into organic waste gas, inorganic waste gas and dusty waste gas, organic waste gas such as methyl benzene and dimethyl benzene, inorganic waste gas such as HCl, H2S, NOX and the like, dusty exhaust gas such as oxidation in various metal smelting processes Dust, stone dust in the ore processing and more. Inorganic emissions mainly include sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds. Inorganic waste gas treatment technology Inorganic waste gases, such as HCl, are typically treated with a liquid spray. H2S is also treated with photolysis. Dust and other gas treatment technology Dust generally cyclone / bag / electrostatic dust-based, according to the need to choose a different treatment process. 3, odor and VOCs A wide range of odor gases, usually including sulfur, nitrogen, oxygen and hydrocarbons and other compounds, divided into two categories of organic and inorganic, specifically refers to: (1) sulfur compounds such as hydrogen sulfide, carbon disulfide, mercaptans, thioethers, methylsulfides; (2) nitrogenous compounds, such as ammonia, trimethylamine, amide, indole, etc .; Hydrocarbons: such as alkanes, alkenes, aromatic hydrocarbons, halogenated hydrocarbons; Oxygen-containing organic compounds: such as alcohols, phenols, aldehydes, ketones, organic acids, etc .; Benzene: such as benzene, toluene, xylene, coking benzene. Common malodorous gas composition characteristics: Amine CH3NH2 (CH3) N gas, soluble in water, soluble in alcohol, ether, benzene and other organic solvents Fishy NH3 gas ammonia, soluble in water, soluble in alcohol, ether organic solvents, irritating taste Methyl mercaptan CH4S gas, insoluble in water, soluble in alcohol, ether, benzene and other organic solvents Methyl sulfide C2H6S liquid, insoluble in water, soluble in alcohol, ether, benzene and other organic solvents H2S H2S gas, soluble in water, soluble in alcohol, ether, benzene and other organic solvents, rotten egg flavor Carbon disulfide CS2 gas, insoluble in water, soluble in alcohol, ether, benzene and other organic solvents, irritating taste Polyethylene wax (PE WAX), also known as polymer wax referred to as polyethylene wax. Because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance and has been widely used.

1. Used as excellent external lubricant in PVC profile, pipe, pipe fitting, foam board, WPC products ,etc. It has good late-period lubricating ability ,and will bring more glossy appearance and lower processing torque.
2. Used as efficient dispersant in masterbatch , filled masterbatch, modified masterbatch and functional masterbatch. It makes the products inorganic components and pigments dispersed better, and get more beautiful appearance .
3. Used as excellent external lubricant in PVC stabilizer , especially in Ca-Zn stabilizer. Additional use suitable inner lubricant, it will highly improve the overall effect of stabilizer and increase the cost-effective correspondingly.
4. Used in hot melt adhesives can better adjust the products viscosity and hardness, improve its fluidity. .
5. Used in paint, coating and the road marking paint,its main performance is heat resistance, deforming ,leveling, anti-setting and dispersion. It can increase the products surface hardness, wear-resistance and anti-smearing properties.
6. Used as modifier in paraffin wax, and improve the paraffin`s melting point , crystallinity ,etc.
7. Used as releasing agent and protective agent in rubber .
