application

Polyvinyl chloride pipe, also claiming pvc pipe, is the tubing that the thermal plasticity high polymer that formed by polymerization of vinyl choride monomer is made, take polyvinyl chloride (PVC) RESINS as main raw material, add appropriate antiaging agent, properties-correcting agent etc., the material forming through techniques such as mixing, calendering, vacuum formings.

Pvc pipe resistance to corrosion is strong, it is bonding to be easy to, PVC has very strong resistibility to oxygenant, reductive agent and strong acid.But it can be corroded and the also inapplicable occasion contacting with aromatic hydrocarbon, chlorinated hydrocarbon as the vitriol oil, concentrated nitric acid by dense oxidizing acid.

But, pvc pipe, particularly UPVC pipe resistance toheat is poor, and environment tensile strength declines more than 60 ℃, and under low temperature environment, Vybak water shoot resistance to impact shock reduces.In transportation, installation and use process, easily there is brittle rupture; In addition, the performance that pvc pipe withstands shocks is also poor.

A kind of high tenacity polychloroethylene pipes, to be made by the component of following weight part:

100～150 parts of polyvinyl chloride (PVC) RESINS,

20～30 parts of chlorinated polyvinyl chloride resins,

6～8 parts of acrylic resins,

2～4 parts of Poly(Trimethylene Terephthalate),

3～6 parts of urethane,

10～15 parts, styrene-butadiene rubber(SBR),

3～6 parts of maleimides,

1～2 part of methyl methacrylate,

1～2 part of dibasic lead phosphite,

2～4 parts of silicon carbide whiskers,

1～2 part, glass fibre,

2～3 parts of polymeric amide,

2～4 parts of diphenyl phosphites,

2～3 parts of stablizers,

2～6 parts of Chlorinated Polypropylene III acid-butadiene-styrene copolymer,

1～2 part of antiaging agent,

1 part of aluminium sesquioxide, silica 1 part,

1 part of titanium dioxide,

2～3 parts of mullites,

1～2 part of titanate coupling agent,

6～10 parts of lubricants,

2～3 parts of tinting materials.
