Apparent density apparent density is the mass per unit volume of uncompressed powder

The apparent density of polyvinyl chloride (PVC) brains in the standard shall be determined according to GB/T2002

It is related to the particle shape, average particle size and particle size distribution of the resin.It is affecting resin growth

Plasticizer absorption, material mixing, product molding important factors, low apparent density has many

The hole structure of polyvinyl chloride marriage tree, easy to plasticizer and other additives in the mixing phase of absorption and

Diffusion, easy to form a more uniform dry mix, so as to ensure the performance of products, dense appearance

Degree quotient, tree layout, is conducive to the formation of shear heat and mixing of the original poplar

Plasticizing, easy to mix evenly and fully
