Description

A kind of polyvinyl piping materials formula

Technical field

Present invention relates particularly to a kind of polyvinyl piping materials formula.

Technical background

Plastic pipe is the chemical building material that high-tech is composited, and chemical building material be continue steel, After timber, cement, the fourth-largest class New Building Materials that the present age is emerging.Chemical building material is at me State achieves being widely used of rapid progress fast development, especially novel environment friendly plastics tubing, Start a sound and substitute the revolution of traditional construction material.Plastic pipe because of have current loss little, energy-conservation, The advantage such as material-saving, protecting ecology, completion are convenient, be widely used in building water supply and drainage, cities and towns to The field such as draining and Gas Pipe, becomes the main force of new century urban construction pipe network.

Plastic pipe, compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement, has Energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construct and keep in repair The advantages such as simplicity, length in service life, are widely used in building water supply and drainage, town and country plumbing, city The building industry such as city's combustion gas, electric power and cable jacket, industrial fluids conveying, agricultural irrigation, municipal administration, Industry and agriculture field.

Plastics are different with traditional material, technological progress paces faster, constantly occur is new Technology, new material, new technology make the advantage of the relatively conventional material of plastic tube more and more prominent.Mould Material tubing, compared with traditional metal tube and pipe of cement, has lightweight, is typically only metal tube 1/6-1/10, have preferable corrosion resistance, shock resistance and tensile strength, plastic tube inner surface Than cast iron pipe smooth many, coefficient of friction is little, fluid resistance is little, can reduce water delivery energy consumption 5% Above, synthesis energy saving is good, manufactures the right reduction of energy consumption 75%, convenient transportation, installs simple, makes With the life-span up to 30-50.Plastic pipe develops quickly in countries in the world, and developed country is giving It is not only a large amount of for replacing that water field and gas burning field application have accounted for absolute advantage plastic pipe Traditional steel pipe, cast iron pipe etc., reason is that technological innovation.On the one hand material has great Progressive；On the other hand application technology has new development, makes traditional piping material this side of applicable employing The occasion of method does not has competitiveness at all.A lot of new materials, new technique is also had to study, or Found out on probation examine to, can affirm, the technology of 10 years plastic tubes is entered from now on Step will promote plastic tube more quickly to develop, more extensively.

China's plastic conduit develops quickly, and quality is improving constantly.At present, preliminarily formed with Polrvinyl chloride (PVC-U) pipe, polyethylene (PE) pipe and polypropylene (PP-R) Guan Weizhu's Plastic tube industry.Wherein polyethylene (PE) pipe due to himself uniqueness advantage by widely should For building water supply, construction drainage, buried drain pipe, building and heating, gas transmission and distribution, gas transmission Pipe, electrician and telecommunication protection sleeve pipe, industrial pipe, agricultural pipe etc..It is mainly used in city City's water supply, city gas supply and field irrigation.PE, is polyethylene (Polyethylene of The english abbreviation of raised temperature resistance), general PE tubing feed pipe The range of application in road is the temperature less than 40 DEG C, it is impossible to for delivery pipeline.PE tubing It it is a kind of degree of crystallinity thermoplastic resin high, nonpolar.The milky appearance of ortho states HDPE, It is a certain degree of translucent in meagre cross section.PE have excellent resistance to great majority life and The characteristic of chemicals for industrial use.

The production technology of China's new material falls behind, and most equipment all needs import, adds external The impact of enterprise so that manufacturing enterprise of China faces the market test of sternness.But it is as various New material, new equipment and new technology are constantly emerged in large numbers, and the plastic pipe of China will be promoted towards product Kind of variation, customizations and possess multi-functional plastic pipe direction and develop.Therefore, poly-second Alkene (PE) pipe application is the most constantly expanding, but due to the material of polyethylene tube self Material characteristic so that not as metallic conduit in terms of intensity and hardness, thus in some application scenarios Limited.It is modified the most on its basis, develops high-performance, and meet international standard Product, can largely expand its use field.
