Metal clothing products of gas source is introduced in everyday life
Printing is given priority to with solvent ink, the ink contains a large amount of solvent. Using solvent ink will be produced in the process of printing, drying and so on benzene, toluene, xylene, acetone, butanol, acetone and ethyl acetate VOCs pollution. Water-based ink low content of the organic solvent to the %, of polyethylene film table is printed can also, but the difficulty, of can, difficulty of HDPE LDPE, monochrome can be fuzzy, but the color matching line. Drying equipment to increase the infrared drying device, speed up the factor. Compound acrylic and polyurethane adhesive is given priority to with ethyl acetate solvent at present. Spray coating can eliminate weld metal clothing products surface gate mark, mark, black spots, and crystal defects, bubble and so on, to give products with conductive, antistatic, flame retardant, wear-resisting, etc, can also be dark suit metal products into light color products. These needs are often spraying a layer of acrylic ester or urethane coatings. Release agent with dichloromethane, dichloroethane and other organic solvents. Hot working gas hot working of volatile gas in addition to including the VOC, there could be hydrogen chloride and hydrogen sulfide, carbon dioxide and water, sulfur dioxide, and so on. Residual gas sources include resin synthesis, additives added, processing decomposition of three parts. ( ) Resin synthetic raw material residual residual raw materials mainly include monomer, solvent, catalyst, emulsifier and molecular weight regulator, etc. ( ) Adding additives including packing, plasticizer, stabilizer, lubricants, pigment and other additives, the small molecule additives such as stearic acid, paraffin wax, polyethylene wax, EBS, antioxidant, zinc stearate, etc. ( ) Thermal decomposition gas each kind of metal clothes has a decomposition temperature, in the process of high temperature processing, metal clothes more or less will be resolved with a small amount of gas material
