Features and Uses of PVC sheet

The high-speed extruder adopts a slotted barrel (water-cooled forced feeding section) and a barrier type (or reactive) special screw with a special mixing structure to realize the high speed and efficiency of the PVC sheet extrusion process.
The coat hanger-type die adopts a special double throttling design to make the thickness of the extruded sheet more accurate.
The temperature is controlled at ±1°, which can accurately control the plasticizing process and the thickness and flatness of the sheet.
The three-roll calender adopts horizontal, vertical or 45-degree inclined type, which can be raised and lowered freely.
The independently controlled roller temperature control system can accurately control the temperature of the pressure roller, so that the thickness of the sheet is uniform.
The winding table device adopts an advanced torque motor, which can adjust the speed and winding tension at will.
PVC sheet equipment production process:
Raw material pre-crystallization treatment; --- Heat, transport and compress the materials with an extruder; --- Disperse and mix the materials, homogenize the solution, and then enter the filter and flat extrusion die at a stable pressure; --- Melt filtration; ---Solution is homogeneous and stable pumping out; ---Co-extrusion distribution is homogeneous and layered; ---Melt is uniformly divided in the die, quantitatively and stably extruded; ---Die molding; ---Three-roll pressing Sheet, cooling, shaping; ---cut scrap edges to the required width size; ---natural cooling and conveying the sheet; ---hand-rolled scrap-edge; ---stabilized traction of the sheet; constant tension feedback of the hand-rolled sheet







Features and uses of PVC sheet:
PVC sheet has high strength, good temperature resistance and good corrosion resistance. Adding additives can meet the requirements of increasing strength, toughness, hardness, flame retardancy and printing.
PVC extruded transparent sheet has the characteristics of flame retardant self-extinguishing, high quality and low price, high transparency, good surface gloss, few crystal points, small water lines, strong impact resistance and easy molding. It is widely used in various tools, toys, Blister, folding box, packaging, etc. in electronics, food, medicine, clothing and other industries.
PVC transparent soft board soft curtain is a replacement product of traditional cotton curtain. This product is soft, transparent, insulated, safe, green, environmentally friendly, acid and alkali resistant, no odor, easy to clean, etc. It can keep cold, heat preservation, energy saving, dustproof, windproof, moisturizing, anticorrosive, fireproof, antistatic, and strong. Light, anti-ultraviolet, sound insulation, table mats, daylighting, industrial vibration reduction, safety warnings, floor and walls, surface protection of utensils and paint film protection, can be used for freezing, food, printing, textiles, electronics, instruments, pharmaceuticals, storage, Shopping malls and other places. It has a good effect on the insulation of live working places and the interruption of harmful arcs.
