CHLORINATED POLYVINYLCHLORIDE
RESIN (CPVC)
CPVC chlorinated method is aqueous suspension (slurry)
chlorided. Under the certain conditions using the special-purpose
PVC resin and the chloride ion Carried on the permutation reaction
to obtain the corresponding model CPVC resin. its molecular
structure is: - CHCl-CHCl-CH*-CHCl-
Because chlorinity increase, CPVC molecular not neat
increases (crystallinity in the structure to drop, molecular
chain's polar enhancement), thus causes its thermal deformation
temperature rise. The CPVC product's application temperature may
reach *****0℃, compares the PVC
enhancement ****0℃, simultaneously
improved the PVC anti-chemical properties and corrosion resistance
ability, can resist the anti-strong acid, the strong alkali, the
salt, the fatty acid salt, the oxidant,the halogen and other
chemical etching. Moreover, the CPVC tensile strength, the
anti-bending strength compares PVC also to have the improvement.
Compared with other polymer materials, CPVC has excellent
resistance to aging, corrosion resistance and high flame resistance
and so on.

Because CPVC has so superior high temperature,
corrosion resistance and flame retardant performance that it has
been widely used in making each different industry pipeline,hot and
cold pipeline and fire pipeline. The advantages of CPVC pipe can be
reflected in the following areas:
1, strong, thermostableBecause CPVC
compares PP-R, PE-X to be firm.Compared with PP, the PE-X
tube,under the similar pressure, CPVC may use a smaller caliber to
achieve the same water flow, thereby saving material costs and
installation time. Compares with other thermoplastic, CPVC has the
remarkable mechanical property under the different temperature, is
suitable for the bearing the situation, the application temperature
may reach as high as *3℃, the life may
amount to *0 years.
2, easy installation The connection method
are very similar with PVC. Most commonly used and simple connection
method is resolver cementation.Other connection methods are
threaded connection, flange connection and electrode
connections.
3, non-corrosive oxygen permeability
CPVC have the anti-oxygen, therefore the oxygen seepage
from the radiator will not bring metal corrosion.
4, reducing the infiltration of additives In order to
prevent oxidation, some modified plastics needs to increase the
massive antioxidant that may be infiltrated into the water supply
system ,causing the ill-smelling smell. 5, without the impact of
chlorine in waterA lot of polyolefin materials
(including PP, PE) may be decomposed with water, while CPVC is not
affected by the impact of residual chlorine in water that there is
no cracks and leakage.6, good flame
retardancyCPVC limiting oxygen index is *0, therefore
it will not burn in the air. It has the characteristics : misfires
the flame decoction,not to increase the fire set,restrict flame
spread,low smoke generation.
7, CPVC has excellent chemical resistance to non-polar
strong acid and alkali. Commonly used to substitute the metal to
process the corrosive material, such as the poor quality of water,
acidic material alkaline matter and other peroxide
solutions.
8, the low thermal conductivityCPVC thermal
conductivity is only 1.*5. heat is not easy to disseminate from the
pipeline, heat loss of pipeline is low.9, bacteria
breeding is not easyCPVC is not influenced by the
impact of residual chlorine in water. So it will not result in
cracks and leaks.Inner wall of pipe is smooth, not easy to breed
bacteria. The research indicated that the breeding of germs in CPVC
pipe is far lower than other materials such as copper, steel and
other plastic pipe.*0, low thermal
expansionCPVC thermal-expansion coefficient is lower
than other plastics. The tube expansion is very small when
tube-pass heat, unlike other types of channels (such as PP-RRP) due
to the higher temperature caused by heat expansion coefficient that
could cause snake bending,the existence safe hidden danger and
eyesores.
*1, the test of timenone of a thermoplastic
material such as CPVC,avoid the maintenance after *0 year hot water
system's test, and displays its excellent performance.
