Description
Technical field
The present invention relates to a kind of chliorinated polyvinyl chloride water-feeding pipes。
Background technology
Plastic pipe is the chemical building material that high-tech is composited, and chemical building material is after steel, timber, cement, the fourth-largest class New Building Materials that the present age is emerging。Chemical building material achieves rapid progress fast development in China, especially the widely using of novel environment friendly plastics tubing, and has started a sound and has substituted the revolution of traditional construction material。Plastic pipe, because having the advantages such as current loss little, energy-conservation, material-saving, protecting ecology, completion is convenient, is widely used in the fields such as building water supply and drainage, cities and towns plumbing and Gas Pipe, becoming the main force of new century urban construction pipe network。
Plastic pipe is compared with the pipelines such as traditional cast iron pipe, coating steel pipe, pipe of cement, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance simplicity, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable jacket, industrial fluids conveying, agricultural irrigation。
Plastics are different with traditional material, technological progress paces faster, the new technique that constantly occurs, new material, new technology make the advantage of the relatively conventional material of plastic tube more and more prominent。Plastic pipe is compared with traditional metal tube and pipe of cement, have lightweight, it is typically only the 1/6-1/10 of metal tube, has good corrosion resistance, shock resistance and tensile strength, plastic tube inner surface more smooth than cast iron pipe many, coefficient of friction is little, fluid resistance is little, can reduce water delivery energy consumption more than 5%, synthesis energy saving is good, manufactures the right reduction by 75% of energy consumption, convenient transportation, installing simple, service life is up to 30-50。Plastic pipe develops quickly in countries in the world, and developed country applies at feedwater field and gas burning field that to have accounted for absolute advantage plastic pipe not only a large amount of for replacing traditional steel pipe, cast iron pipe etc., and reason is that technological innovation。Material has great progress on the one hand；On the other hand application technology has new development, makes traditional piping material not have competitiveness being suitable for the occasion adopted in this way at all。Also have a lot of new materials, new technique to study, or found out on probation examine to, it is possible to certainly, the technological progress of 10 years plastic tubes from now on will promote plastic tube more quickly to develop, more extensively。
CPVC feed pipe is with chlorinated polyvinyl chloride resin for primary raw material, extruded machine extrusion molding and a kind of novel water feed tube of producing。The maximum advantage of CPVC feed pipe purposes is that comparison is high temperature resistant。If the raw material of molding CPVC pipe has the graphite-filled material of relatively larger ratio, can also be used with and do heat pipe, the application at home of this tubing is inchoate in recent years, it is used in the water delivery of hot and cold water, heat chemistry solution and waste liquid transfer pipeline more, life-time service transfusion temperature reaches as high as 120 degrees Celsius, and the life-span was up to 40 years。
Chlorinated polyvinyl chloride pipe has the advantage that
1, the hot strength of chlorinated polyvinyl chloride pipe, bending strength, bending modulus and bearing capacity are all higher than chlorinated polyvinyl chloride pipe, polyvinyl chloride pipe and polypropylene tube。
2, chemical resistance, thermostability and weatherability are higher than polyvinyl chloride pipe。
3, do not affected by chlorine in water during conveying drinking water, it is ensured that drinking water quality。
4, anti-flammability is excellent, does not produce drippage during burning, and burning diffusion is slow, does not produce toxic gas。
5, pliability is good, easy for installation, can connect with solvent。
The production technology of China's new material falls behind, and most equipment all needs import, adds the impact of external 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 constantly to emerge in large numbers, the plastic pipe promoting China towards diversification of varieties, customizations and is possessed multi-functional plastic pipe direction develops。Therefore, chliorinated polyvinyl chloride (CPVC) pipe application constantly expands in recent years, but itself voltage endurance capability is not good, therefore it is modified on its basis, develop high voltage endurance capability, and meet the product of international standard, can largely expand its use field。
