Description

A kind of hard polvinyl choride pipe formula
Technical field
The present invention relates to a kind of hard polvinyl choride pipe formula.
Background technology
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.
Hard polvinyl choride pipe, is to use after Corvic coordinates with stabilizer, lubricant etc. Pressure sintering is extruded, is the plastic pipe being developed and applied the earliest.PVC-U pipe is anticorrosive Ability is strong, be prone to bonding, price is low, quality is hard, but owing to having PVC-U monomer and adding Add agent to ooze out, be only applicable to delivery temperature less than in the water supply system of 45 DEG C.Plastic conduit For carrying drinking water, waste water, chemicals, add hydrothermal solution and coolant, food, ultrarapture liquid, The application of mud, gas, compressed air and vacuum system.
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, the most poly- Vinyl chloride pipe application is the most constantly expanding, but due to hard polvinyl choride pipe self Material behavior so that not as metallic conduit in terms of intensity and hardness, thus in some applied field Conjunction is limited.It is modified the most on its basis, develops high-performance, and meet international mark Accurate product, can largely expand its use field.
