Description
Technical field
The present invention relates to a kind of high-strength corrosion-resisting CPVC formulating of recipe for pipes.
Technical background
Plastic pipe is the chemical building material that high-tech is composited, and chemical building material is after steel, timber, cement, the 4th big 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 the revolution that a sound substitutes 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 line, becoming the main force of new millennium urban construction pipe network.
Plastic pipe is compared with the pipelines such as traditional cast iron pipe, galvanized steel pipe, cement pipe, 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, it is widely used in construction industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and optical cable sheath, industrial fluids conveying, agricultural irrigation.
Plastics are different with traditional material, technical progress paces faster, the new technology that constantly occurs, novel material, novel process make plastics tubing more and more outstanding relative to the advantage of traditional material. Plastic pipe is compared with cement pipe with traditional metal tube, there is weight light, the 1/6-1/10 being generally only metal tube, has good erosion resistance, shock resistance and tensile strength, plastics tubing internal surface more smooth than cast iron pipe many, frictional coefficient 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, install simple, it may also be useful to the life-span reaches 30-50. Plastic pipe is very fast in countries in the world development, and developed country has accounted for absolute advantage plastic pipe and has not only been used in a large number replacing traditional steel pipe, cast iron pipe etc. in feedwater field and gas burning field application, and reason is just technological innovation. Material has great progress on the one hand; On the other hand utilisation technology has new development, makes traditional piping material not have competitive capacity being applicable to the occasion adopted in this way at all. Also have a lot of novel material, new technology to study, or found out on probation examine to, it is possible to certainly, the technical progress of 10 years plastics tubings from now on will impel plastics tubing to develop more rapidly, more extensively.
CPVC water service pipe is main raw material taking chlorinated polyvinyl chloride resin, a kind of novel water feed tube produced through extruder for shaping. The maximum advantage of CPVC water service pipe purposes is that comparison is high temperature resistant. If when the raw material of shaping CPVC pipe has the graphite-filled material than larger proportion, also can be used to do heat conduction pipe, the application at home of this kind of tubing just just started in recent years, in the multiplex water delivery at cold and hot water, thermochemistry solution and waste liquid transfer line, life-time service transfusion temperature reaches as high as 120 degrees Celsius, and the life-span reaches 40 years.
Chlorinated polyvinyl chloride pipe has the following advantages:
1, the tensile strength of chlorinated polyvinyl chloride pipe, flexural strength, modulus in flexure and bearing capacity are all higher than chlorinated polyvinyl chloride pipe, polyvinyl chloride pipe and polypropylene tube.
2, chemical resistance, thermotolerance and weathering resistance are higher than polyvinyl chloride pipe.
3, carry and do not affect by chlorine in water during tap water, ensure drinking water quality.
4, flame retardant resistance is excellent, does not produce drippage during burning, and burning diffusion is slow, does not produce toxic gas.
5, snappiness is good, easy for installation, can connect with solvent.
The production technology of China's type material falls behind, and most equipment all needs import, adds the impact of external enterprise so that manufacturing enterprise of China faces severe market test. But along with various novel material, new installation and novel process are constantly emerged in large numbers, towards diversification of varieties, customizations by impelling the plastic pipe of China and possess multi-functional plastic pipe direction and develop. In recent years, along with the continuous destruction of physical environment, causing global climate to change a lot, easily there is the severe weather such as acid rain, salt fog in a lot of area, erosion resistance to CPVC tubing is had higher requirement, to meet its service requirements in inclement weather. Easily there is low temperature brittleness cracking phenomena in life-time service, greatly reduces its work-ing life, if simultaneously original insufficient strength, then can greatly degree affect its work-ing life, cause CPVC pipe to damage. Therefore carry out modification on its basis, exploitation high-performance, and meet the product of international standard, its use field can be expanded to a great extent.
