PVC, the full name of Polyvinylchlorid, the main component is polyvinyl chloride, and other ingredients to enhance its heat resistance, toughness, ductility and so on. The uppermost layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the lowermost layer is a back-coated adhesive. It is a well-loved, popular and widely used synthetic material in the world today. The global use of PVC pipes ranks second among various synthetic materials.
1, UPVC pipe
The largest application of UPVC pipes is in the construction industry. It is currently used in tap water pipeline systems and residential water pipes in various provinces and cities across the country. It is mainly used as a drain pipe, rainwater pipe and threading pipe in the construction industry. UPV tube has chemical corrosion resistance, self-extinguishing and flame retardancy, good resistance to tempering, smooth inner wall and good electrical properties, but UPVC pipe has low toughness, large linear expansion coefficient and narrow operating temperature range. The UPVC pipe has obvious benefits. The production and use of UPVC pipes is 55-68% more energy efficient than cast iron pipes. The production and use of UPVC water pipes is 62-75% more energy efficient than galvanized pipes, and the price per unit length is only 1/1 of galvanized pipes. 2, the installation cost is 70% lower than the galvanized pipe, the use of 1 ton UPVC water supply pipe can replace 12 tons of cast iron pipe, the use of 1 ton UPVC bellows can save 25 tons of steel.
2, core layer foam tube
The core foaming tube is the same as the ordinary UPVC pipe produced by the three-layer co-extrusion process. The middle is a new type of pipe with a relative density of 0.7-0.9 low foaming layer. The hoop rigidity is ordinary UPVC pipe. 8 times, and the stability of the ruler is good when the temperature changes, the heat insulation is good, especially the foamed core layer can have the transmission of the barrier noise, and is more suitable for the drainage system of the high-rise building.
The foamed core tube can save more than 25% of the raw material compared with the solid wall pipe, and the inner wall pressure resistance is greatly improved. The core layer foaming silencer tube with a plurality of convex spirals on the inner wall, the water flows freely and continuously along the inner wall of the tube, forming a gas column in the center of the drain pipe, so that the pressure inside the pipe is reduced by 10%, and the universal capacity is increased by 10 times. The displacement is increased by 6 times and the noise is 30-40db lower than that of ordinary UPVC drains.
3, PVC radial reinforcement tube
This kind of pipe is made of special mold and forming follow-up device. It is a heavy-duty large-diameter super-strength ring-shaped glass pipe. The utility model is characterized in that the outer wall of the pipe is provided with radial reinforcing ribs, which can greatly improve the rigidity and compressive strength of the pipe ring, and is particularly suitable for drainage in municipal engineering.
4, double wall corrugated pipe
The double-wall corrugated pipe is made by extruding two concentric pipes at the same time, and then welding the outer pipe of the bellows to the copper pipe with smooth inner wall. It has a smooth inner wall and a corrugated outer wall. It is light in weight and high in strength. It can save 40-60% of raw materials than ordinary UPVC pipes. It is mainly used as communication cable protection pipe, building exhaust pipe and agricultural drainage pipe.
5, PVC transparent time tube
It is made by extrusion of two layers of plastic inside and outside, with synthetic fibers sandwiched in the middle, which is flexible and bendable. PVC transparent tube has good acid resistance, alkali resistance, oil resistance and aging resistance, can replace rubber tube, and is cheap. It is widely used for the transportation of nitrogen, oxygen, carbon monoxide and other gases, water, dilute alkali, oil and other liquids. It can also be used as a conduit for water heaters, sprayers, gas stoves, etc.
6, CPVC pipe
CPVC pipe is a heat-resistant plastic pipe processed from chlorinated polyvinyl chloride containing up to 66% chlorine. The heat-resistant temperature of CPVC pipe is 30°C higher than that of UPVC pipe, and the dimensional stability is improved, and the coefficient of linear expansion is lowered. CPVC pipe is excellent in heat resistance, aging resistance and chemical corrosion resistance, and is not deformed in boiling water. It can be used for the transportation of hot water, corrosion resistant liquid and gas. Domestic Youli Co., Ltd. produces CPVC pipe.
Chuck Flap Wheel
Chuck type flap wheel is a kind of coated abrasives, each product is glued with hundreds of gauze sheets.
