The most intuitive function of raw material mixing in the process of PVC plastic steel tile equipment is to mix all kinds of auxiliaries in the formula evenly in PVC resin through the mixing equipment, so that the auxiliaries can play an vital important role in ensure that the products have excellent properties.


For the simple mixing of PVC plastic steel tile equipment under general conditions, the powder auxiliaries can not be dispersed and mixed evenly in the PVC resin, they will exist in the mixing system in the form of aggregates, and the plasticized molecules can not be completely dispersed into the PVC resin. Under the shear action of the mixer, the PVC particles are repeatedly broken into primary particles, the powdered auxiliaries aggregates are further dispersed, and the auxiliaries and resins become smaller particle morphology with larger contact surfaces that are easier to adsorb and "combine" with each other. In the mixing process of PVC plastic steel tile equipment, shear heat or / and external heating will increase the temperature of the mixed material, the molecular chain of PVC will become more active with the increase of temperature, and the swelling amount of particles will increase, which is convenient for the diffusion and absorption of plasticizer and increase the absorption of auxiliaries. Low melting point auxiliaries, such as lubricants, will become liquid as the temperature increases and will disperse into the pores of resin particles like plasticizers. Therefore, a very important point of the PVC plastic steel tile equipment process is that through the high-speed mixer and the raw materials that reach a certain mixing temperature, the PVC formula components can be organically dispersed and evenly mixed, ensuring the subsequent plasticizing of the materials and the consistency of molding.
