Mix and mix the ingredients in the right way
In general, PVC resin particles, fillers and additives need to be prepared. They need to be put into the high and low temperature mixer in turn with a certain weight for full and even mixing. And PVC building formwork manufacturers introduced that under the action of high temperature, friction and shear, these materials will have special changes, and they are very evenly mixed together, and then the discharge becomes the main material of PVC building formwork we need to use.
To adopt coextrusion foaming
When making PVC building formwork, it is necessary to use two extruders to complete the total foaming process, and put the pre mixed skin material in it, and then put the mixed core material into it, so that the formwork can form a three-layer sandwich structure. In addition, the manufacturer of the crust foaming template introduces that in this process, it enters the mold for foaming, and adjusts the thickness of the blank plate through the die lip.
To be cooled and shaped
In order to make the formwork reach enough hardness after being made, the PVC building formwork manufacturer emphasizes that the blank plate should be cooled for special cooling treatment. Understand which reliable manufacturer of PVC building formwork introduces that only in this way can its temperature be reduced to below 50 ° C, and it also needs vacuum treatment. In this state, the material can be transported to the corresponding position, so that it can play a good role in protection.
The above are the key points of PVC building formwork production process, which include several aspects. In addition, it is necessary to carry out such operations as editing, drawing and cutting. The professional manufacturer of PVC plastic building formwork introduces that in the process of traction, it needs to use the corresponding devices, and control the operation force and speed, so as to evenly lead out the formwork and control its thickness, and then carry out the packaging work
