The Solution To The Air Hole In The Middle Of The PVC Foam Board

　　What should I do if there are air holes in the middle of the PVC foam board? This is actually because the PVC foam board manufacturer added a foaming agent in the production, so there will be air bubbles in the middle, which will form pores. The following PVC Sheet manufacturers will answer you in detail.

　　PVC foam board contains foam plastic, also called foam plastic, which is a composite material filled with gas, which is based on plastic and contains a large number of air bubbles.

　　Classification of PVC foam board:

　　According to the different foaming ratios, it can be divided into high foaming and low foaming, and according to the softness and hardness of the foam texture, it can be divided into rigid, semi-rigid, and flexible foams. The cell structure, can be divided into closed cell foam and open cell foam. The common PVC foam sheet is a rigid closed-cell low-foaming sheet.

　　According to several common situations and problems encountered, the editor of Age PVC foam board manufacturer organizes the relevant solutions as follows;

　　One case: large pores in the middle of the plate

　　Problem 1: Extruder temperature setting is high

　　Solution: reduce the temperature (appropriate -5 degrees, fine-tune in a decreasing way, do not fluctuate to cool down)

　　Problem 2: The amount of foaming regulator is small

　　Solution: increase the amount of foaming regulator (similarly: increase by fine-tuning a small unit)

　　Problem 3: Improper Lubrication Adjustment

　　Solution: Properly adjust the lubricant ratio (adjust according to the experience of the boot master, there is no way to specify the parameters)

　　In the second case: the core of the sheet has large cells and the surface cells are small

　　Problem 1: The host temperature is high

　　Solution: reduce the temperature of the host (appropriate -5 degrees, fine-tune in a decreasing way, do not fluctuate to cool down)

　　Problem 2: Improper Lubrication Adjustment

　　Solution: Adjust the lubricant ratio

　　Problem 3: Insufficient melt strength

　　Solution: Add the amount of foam regulator
