The Method of Product Classification in the Production of PVC Paste Resin

Abstract

Disclosed is a method for product grading in polychlorostyrene paste resin production. The method includes sequentially connecting a spray drying tower, one section of a bag filter, a vibration screen, a powder collecting groove, a grader, two sections of a bag filter A, a screw conveyer, two sections of the powder collecting groove, a pulverizer and two sections of a bag filter B. By the aid of a grading device for polychlorostyrene paste resin products, 80% of polychlorostyrene paste resin powder materials do not need to be pulverized, parameters like material roundness are good, post processing performance of the products is good, and the polychlorostyrene paste resin powder materials can be sold as special materials for gloves; one pulverizer can meet needs of product processing of 20% of graded coarse materials which are sold as another kind of special materials, and the number of the pulverizers can be greatly reduced; the method has the advantages that few devices are involved, grading precision is high, cutting of particle diameter can be conveniently adjusted, energy saving and consumption reduction are achieved, economic effectiveness is high and the like. The method is applicable to the product grading process of a polychlorostyrene paste resin drying system.

Description

technical field [0001] The invention relates to a product grading treatment method of a paste resin drying system, in particular, it is suitable for the product grading method in the production of polyvinyl chloride paste resin. Background technique [0002] Paste resin is widely used in PVC gloves, garment leather, luggage leather, PVC car floor mats, foam floor leather, wallpaper, industrial conveyor belts, plastic track, automotive decorative leather, plastic-coated window screens, industrial fabrics, etc. With the continuous development of my country's national economy and the continuous improvement of people's living standards, coupled with the continuous deepening of the application and development of paste resin, the demand for paste resin in the domestic market has a large development space, especially in automobiles, construction, electronics and coatings, etc. On the one hand, the consumption potential is huge. [0003] The particle size of the paste resin after dr...
