What rubbish will the resin craft produce when it is manufactured?

- May 21, 2018 -

Resin crafts production process is generally: the unsaturated resin (containing styrene benzene and other solvents), curing agent (cyclohexanone, methyl ethyl ketone, etc.), stone powder and other spices, grouting molding, polishing, caustic washing, drying, Painting, inspection, packaging and other processes produced. The main environmental factors in the production process are: various mechanical noises, organic waste gas emissions during the grouting process, polishing dust, alkaline washing waste water, organic waste gas painting (including painting), waste gypsum generated from waste molds, waste silica gel, and Waste chemical packaging, waste paint, waste oil, etc. The production process of resin handicrafts and the production of pollutants.

 Different types of resin handicrafts, their production processes are not the same, resulting in pollution sources, pollutants are not the same, resulting in a difference in environmental impact, mainly water pollution, noise pollution, air pollution and solid waste emissions. The auditor should first understand its product and process, determine the adequacy of the environmental factor identification according to the process, and determine the rationality of the corresponding treatment method according to different pollution factors and pollution levels.

Wastewater

  The waste water of the resin handicraft is mainly the white blank alkaline foam, and the waste water produced by the residual alkali liquor and powder on the surface of the white blank is washed with a high pressure water gun. The main pollutants of the waste water are high pH, CODcr, SS, etc. The wastewater is neutralized and coagulated. The control measures can generally meet the discharge standards. Exhaust gas.

The solvent in the unsaturated resin in the process of mixing and grouting will emit a small amount of organic gas. The organic gas components are mainly volatile organic compounds such as cyclohexanone and styrene. Due to the low concentration of organic exhaust gas, ventilation facilities are generally used for pumping.

 The white billet polishing process produces a lot of dust. If it does not manage to pollute the air of the workshop and the ambient air, generally a bag filter can be used to effectively meet the standards. Spray paint exhaust gas, resin crafts spray paint process has a paint mist, paint spray can use water curtain paint or spray paint, if the use of "triphenyl" paint, the exhaust gas should be activated carbon adsorption or catalytic combustion standards discharge. The organic exhaust gas emitted by the painting and painting process mainly affects the air in the workshop and has little impact on the external environment air. Generally, ventilation facilities can be used for pumping.

 Recyclable wastes such as waste gypsum produced in the production process of resin handicrafts can be sold directly to cement; general industrial solid wastes that cannot be recycled can be entrusted to urban solid waste disposal units for disposal. Chemical packaging materials such as waste paint buckets and resin drums can be recovered by suppliers. Waste wastes such as spent caustic liquid, waste resin, and paint residue should be entrusted to a qualified unit to be safely disposed of or recycled.
