Polyvinyl chloride soft board (PVC soft board): PVC resin as the main raw material, calcium carbonate as the filler, plus plasticizers, stabilizers, lubricants and an appropriate amount of color paste, obtained by extrusion molding method Quality PVC sheet. Because PVC soft board has good corrosion resistance, flexibility, insulation, elasticity, convenient lining construction, fast speed, and low cost, it is often used in chemical anti-corrosion construction, especially in lining, There are many applications. In recent years, PVC flexible boards have also been applied to the floor laying in laboratories, factory processing areas, and special office areas.


Plastic plate production line is also a kind of plastic machinery. Sheet production line, sheet extruder, sheet mechanical equipment, sheet machine, sheet production line, sheet equipment, sheet extruder.

1. Horizontal three-roller single sheet machine / plate production line:

★ The unit is mainly composed of a host, a screen changer, a mold, a tablet press, a conveyor, a tractor, a cutter, a stacker, or a winder;

★ The gear box is made of cast steel, the gear is made of alloy steel and processed by gear grinding, and the lubrication points in the box are forced lubrication. The lubricating oil is equipped with an efficient water cooling system.

★ The screw material is made of 38CrMOA1A high-quality nitrided steel, and after nitriding treatment, the surface is sprayed with alloy.

★ The barrel material is made of 38CrMOA1A high-quality nitrided steel, and after nitriding treatment, the surface is sprayed with alloy.

★ The raw materials that can be processed are: PP, PE, PVC, PS, ABS, etc .;

★ This unit is mainly suitable for: stationery products (such as file folders), plastic products (such as plastic cups, plastic biscuit boxes, etc.) advertising fields (such as billboards, etc.)

2. Horizontal three-roller double-machine co-extrusion sheet production line:

★ The unit is mainly composed of a host, a screen changer, a mold, a three-layer distributor, a tablet press, a conveyor, a tractor, a cutter or a reel, etc .;

1. PVC plastic sheet production line is preheated at startup: this is to heat the mold before startup, and it needs to be preheated to be closed and heated.

2. Clamping: Reasonable adjustment of mold opening and closing strokes is beneficial to improve product demoulding and product feeding effect.

3. Preheating of PVC plastic plate production line: steam enters the solid transfer mold, preheats the mold, so that the mold is preheated, and the condensed water and cold air during the retention period are discharged. Function: Increase the mold temperature and strengthen the apparent fusion of the product.

4. Penetration heating: improve the core and internal fusion of the product. Penetrating heating consumes steam and wastes steam more seriously.

5. Heating on both sides: further enhance the heating effect and improve the surface quality of the product.

6. Return to temperature (insulation): All valves are closed to make full use of the residual heat of the mold, so that the product is heated and heated. It is conducive to product surface fusion and can save energy (steam).

7 Vacuum cooling: The vacuum valve is opened, and the vacuum pump is used for vacuuming. The residual heat and moisture in the mold and products are all evacuated, and part of the foaming agent is pumped out to avoid product swelling. Negative pressure is formed in the mold, which is beneficial to the demolding of the product.
