Does the owner who is being renovated in the winter knows? There are six types of construction materials that are no longer suitable for use in home renovation due to environmental or safety issues! However, many decoration teams are still trying to use cheap, which will give your love home decoration brings a lot of hidden dangers. Below, teach you to use tricks to identify and eliminate building materials.

First, resin rock wool
Appearance: pipe insulation or insulation wall.
Prohibited reasons: poor insulation effect, large energy consumption in the production process, and great harm to workers' health during construction.
Alternative materials: polyurethane insulation pipe, rock wool insulation pipe and glass wool insulation pipe. Home use more mineral wool, that is, glass wool insulation pipe, insulation effect is good.
Tip: This material will still be used by the guerrillas and can be seen through the look: resin rock wool looks rough and has earthy colors; glass wool has yellow color and exquisite workmanship.
Second, incandescent lamps, halogen lamps
Prohibited reason: This kind of illuminating light source that emits light by heating tungsten wire has high energy consumption, short life span, high temperature, low light efficiency and poor safety.
Alternative materials: energy-saving lamps, LED lamps and other green lighting products. Xi'an Decoration Company Donghao Decoration
Third, non-alkali glass fiber mesh cloth
Appearance: Before painting, apply to the wall to prevent cracking.
Prohibited reason: The mortar layer is an alkaline material, and this kind of cloth has poor alkali resistance and is easily damaged. It cannot meet the crack resistance requirements of the mortar layer.
Alternative materials: glass fiber mesh cloth that meets alkali resistance requirements, and frequently used in home improvement are white cloth, kraft paper, etc.
Tip: Some small companies or guerrillas will still use non-alkali fiberglass mesh cloth, the owner can feel and judge by hand touch, this cloth is very soft, after the open, the exposed glass filaments shine.

1, strong, thermostable
Because 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 93°C, the life may amount to 50 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 water
A 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 retardancy
CPVC limiting oxygen index is 60, 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 conductivity
CPVC thermal conductivity is only 1.05. heat is not easy to disseminate from the pipeline, heat loss of pipeline is low.
9, bacteria breeding is not easy
CPVC 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.
10, low thermal expansion
CPVC 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.
11, the test of time
none of a thermoplastic material such as CPVC,avoid the maintenance after 40 year hot water system's test, and displays its excellent performance
