Waste gas from plastic injection molding: Plastic scientific name: PVC, polymer compound polymerized from vinyl chloride, thermoplastic, industrial product is white or light yellow powder, specific gravity is about 1.4 g / cm3, chlorine content is 56% - 58%, melting point is about 70-85 ℃, molding temperature is 160-190 ℃, decomposition temperature is more than 200 ℃. During the pyrolysis process (180-200 ℃), the chain breaking, decomposition and degradation of PVC plastic particles occur due to the shear extrusion between molecules. The free monomer waste gas is generated during the process of degradation, and vinyl chloride and hydrogen chloride monomer are produced from PVC.
The raw material used in the injection molding process is PVC (polyvinyl chloride). HCl and free vinyl chloride may be released from the waste gas. However, if the raw material contains POM (polyoxymethylene), formaldehyde may be released. In addition, due to the complexity of the process waste gas composition in granulation process, some places use the calculation of non methane hydrocarbons for quantitative evaluation, and some places also use the calculation of VOC (volatile organic compounds) for quantitative evaluation. Because the heating temperature during granulation is generally controlled within the allowable range of plastic raw materials, the amount of decomposed monomer is very small, and the heating is generally carried out in a closed container, only a small amount of monomer is discharged. Generally speaking, the monomer produced by thermal decomposition is only 0.01-0.02% of the total amount, calculated as 100-200 g / T product. The composition of waste gas in granulation process is complex, and the composition of waste gas produced by different raw materials is different.

The waste gas treatment equipment of the injection molding machine adopts activated carbon adsorption process

1、 Overview of activated carbon adsorption tower
The best treatment effect of odor treatment equipment is organic adsorption tower. Activated carbon adsorption is an effective measure to remove the odor of water, natural and synthetic dissolved organic matter, micro pollutants and so on. Most of the larger organic molecules, aromatic compounds, Haloalkynes and so on can be firmly adsorbed on the surface or in the pores of activated carbon, and have obvious removal effect on humus, synthetic organic matter and low molecular weight organic matter Activated carbon adsorption tower is a kind of high efficiency, economical and practical device for purification and treatment of organic waste gas; it is also an environmental protection equipment product for waste gas filtration and adsorption of peculiar smell. Activated carbon adsorption tower has the advantages of high adsorption efficiency, wide application range, convenient maintenance, and can simultaneously treat a variety of mixed waste gas. The equipment is an adsorption equipment for purifying high concentration organic waste gas and painting waste gas. It uses the high-strength adsorption capacity of activated carbon and combines with the function of fan to adsorb organic waste gas molecules. It has a good adsorption effect on the waste gas of benzene, alcohol, ketone, ester, gasoline and other organic solvents.

2、 Equipment characteristics of activated carbon adsorption tower: activated carbon adsorption tower is widely used in furniture and wood industry, chemical coatings, metal surface treatment and other spraying, painting, drying and other places producing organic waste gas and odor. High quality adsorption activated carbon is used as the adsorption medium, and the organic waste gas is filtered and adsorbed through multi-layer adsorption layer, so as to achieve the purpose of purifying waste gas.
3、 The performance characteristics of activated carbon adsorption tower are as follows: 1. High adsorption efficiency and strong capacity; 2. Compact structure, small floor area, simple and convenient maintenance and management, and low operation cost; 3. Simultaneous treatment of a variety of mixed organic waste gas; 4. Automatic control operation design, easy and safe operation; 5. Fully enclosed, indoor and outdoor use.
4、 Characteristics of activated carbon adsorption tower process (main technology): it is divided into manual type and automatic type, with compact and integrated structure, easy installation, operation and maintenance; high filtration rate, large treatment capacity, stable operation effect, less equipment occupation; large pollutant interception capacity of filter material, high porosity, friction resistance, and moderate proportion.
5、 Application scope of activated carbon adsorption tower: the activated carbon adsorption tower is suitable for the working environment of low concentration and large air volume or high concentration intermittent emission of waste gas.


6、 The main application fields of activated carbon adsorption tower include: electronic components production, battery (battery) production, pickling workshop, laboratory exhaust, metallurgy, chemical plant, pharmaceutical factory, coating workshop, food and brewing, furniture production and other industries, among which the most suitable for waste gas treatment and purification of injection molding machine.
