Description
Technical field
The present invention relates to a kind of aging resistance hard polvinyl choride pipe formula.
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. ?own rushes down cyperus malaccensis noise captive herds rare (12) record border ? that kneels on the ground with the upper part of the body straight and consults core and dredge ? Kuo bifurcation ? core and cut falcon and gather ? and tease the technological progress of assorted every a few ? ? tip key gap ǎ ? 0 year plastic tube of Yao ? plastic tube will be promoted more quickly to develop, more extensively.
Hard polvinyl choride pipe, is extruded by pressure sintering after Corvic coordinates with stabilizer, lubricant etc., is the plastic pipe being developed and applied the earliest. PVC-U pipe resistance to corrosion is strong, be prone to bonding, price is low, quality is hard, but with PVC-U monomer and additive exudation, is only applicable in the delivery temperature water supply system less than 45 DEG C. Plastic conduit is used for carrying drinking water, waste water, chemicals, adds hydrothermal solution and coolant, food, ultrarapture liquid, mud, gas, the application of compression air and vacuum system.
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, hard polvinyl choride pipe application constantly expands in recent years, but existing tubing ageing resistance is poor, and service life is short. Therefore it is modified on its basis, develops high ageing resistance, and meet the product of international standard, can largely expand its use field.
