PP Corrugated Plastic Sheets are ultra-high molecular weight polyethylene sheets, which have high strength, impact resistance, fatigue resistance, non-toxicity and odorless, low surface tension, and are not compatible with common substances, so they are not easy to stick and connect to dirt. Corrosion resistance: resistant to corrosion by phosphoric acid, hydrochloric acid, dilute sulfuric acid, alkalis, and salts. Small friction coefficient: low flow resistance, saving energy consumption.

PP Corrugated Plastic Sheets are widely used in acid and alkali resistant equipment, electroplating equipment, solar photovoltaic equipment, environmental protection equipment, wastewater and exhaust gas discharge equipment, washing towers, clean rooms, semiconductor plants, and related industrial equipment, and also manufacturing plastic water tanks The first choice of materials, among which PP thick plates are widely used in stamping boards, mattress boards, etc.; advertising billboards; recycling boxes, including reusable recycling boxes, vegetable and fruit packaging boxes, clothes storage boxes, stationery boxes, and industrial boards, including Wire and cable outer packaging protection, glass, steel plate, various items outer packaging protection, pads, racks, partitions, bottom plates, etc. also have its applications.

PP Corrugated Plastic Sheets will produce horizontal stripes. The temperature of the machine head is generally about 5～10℃ higher than the temperature of the machine. The temperature of the machine head is too low, and the surface of the sheet is dull and easy to crack. The temperature of the machine head is too high, the material is easy to decompose and there are pores. The temperature of the machine head is generally controlled to be low in the middle and high at the ends. Temperature control of the three-roller calendar: The temperature of the PP sheet extruded from the die is higher. In order to cool the sheet slowly and prevent the sheet from warping due to internal stress, the three rollers of the three-roller calendar are simply heated and set and adjusted. Temperature devise. The heating medium includes steam, oil, and electric heating. If the temperature of the roller is too low, it is difficult for the plate to stick to the surface of the roller, causing spots, dull surface, poor transparency, and small wrinkles. The surface temperature of the roller should be high enough to make the molten material completely adhere to the surface of the roller, but too high will cause the PP board or sheet to stick to the roller and produce horizontal stripes on the surface. therefore,

1. Streaks that are not tight to the roller can be seen and cannot be touched.

2. The horizontal stripes that can be felt are caused by the resonance of the die head. Increase or decrease the melt flow rate. The methods can be temperature, speed, lubricant.

3. The streaks that can't be detected and indeed come out of the die are caused by unstable speed, usually power supply problems, and the most troublesome thing is mechanical failure.
