Description

PVC board powder aftertreatment equipment

Technical Field

The invention relates to the technical field of PVC plate processing, in particular to post-processing equipment for PVC plate powder.

Background

The PVC board is a board which is made of PVC as a raw material and has a honeycomb-shaped mesh structure in cross section, the PVC board accounts for 60 percent of the largest proportion in the building material industry, and the PVC board is used in the packaging industry and other industries with a plurality of small-range applications. The PVC can be classified into soft PVC and hard PVC according to the degree of softness and hardness. Can be divided into a PVC skinning foaming plate and a PVC free foaming plate according to the manufacturing process. Transparent PVC sheets and PVC sheets can be classified according to transparency and opaqueness.

The PVC sheet material has high surface hardness and excellent scratch resistance; the surface resistance value is 6-10 th-power ohm of 10, the antistatic function is excellent, and the impact resistance and the chemical solvent resistance are outstanding; the appearance is beautiful, and is very flat and smooth; the light transmittance is more than 73%.

The powder for producing the PVC plate has higher requirement, the particle size is required to be distributed between 40 meshes and 50 meshes, the granules are added into a grinding screening device for grinding, and the powder is screened out by the grinding and then directly filled into a plastic bag. The grinding screening equipment converts electric energy into heat energy, the temperature of the ground powder is higher than 50 ℃, in the actual production process, the powder for the PVC plate is gathered in the bag, the heat cannot be dissipated for a while, once the central temperature is higher than 50 ℃, the powder is extremely easy to adhere and agglomerate, and the powder needs to be crushed before use.
