Plastic steel louver - Characteristics of plastic steel louver:

Plastic steel profile is abbreviated as plastic steel. The main chemical composition is PVC, so it is also called PVC profile. It is widely used as a new building material. Because of its physical properties such as rigidity, elasticity, corrosion resistance and excellent aging resistance, it is usually used as a good substitute for non-ferrous metals such as copper, zinc and aluminum.

In housing construction, it is mainly used for push-pull, flat open doors and windows, guardrail, pipe and ceiling materials. Through new process treatment, it is also widely used in automobile engine protection plate. It not only has light weight, but also has good toughness and excellent properties of rigidity. Sometimes it is also called alloy plastic steel.

The unique advantage of plastic doors and windows is that they can gradually replace plastic doors and windows. Compared with aluminum and wooden doors and windows, plastic steel doors and windows have the following advantages:

1. The price is cheap. The price of plastic is much lower than that of aluminum with the same strength and service life. This advantage is becoming more and more obvious due to the sharp rise in the price of metal.

2. Rich colors: the application of colored plastic steel profiles adds a lot of beauty to the building. In the past, wooden doors and windows were used. In order to achieve the harmony between doors and windows and building appearance, paint was mostly sprayed on the surface of doors and windows. The paint is easy to age and peel off in case of ultraviolet light. It will be beyond recognition in a few years, which is very inconsistent with the service life of the building. Later, color aluminum doors and windows were invented, but the price was expensive and ordinary consumers could not afford it. The use of plastic doors and windows perfectly solves this problem, and the color film coated profiles can even make the wood grain effect of confusing the fake with the real.

3. Durability: adding reinforced section steel into the profile cavity greatly improves the strength of the profile and has the effects of earthquake resistance and wind erosion resistance. In addition, the multi cavity structure of the profile has an independent drainage cavity, so that water cannot enter the reinforced section steel cavity, so as to avoid section steel corrosion and improve the service life of doors and windows. The addition of anti ultraviolet components also improves the weather resistance of plastic steel profiles, which can be safely used even in tropical areas with strong ultraviolet rays.

4. Good thermal insulation performance: the thermal conductivity of plastic steel profile is far lower than that of aluminum profile. In addition, the design of multi cavity structure achieves the effect of thermal insulation. The research shows that the indoor temperature of rooms with plastic steel doors and windows in summer is 5-7 ℃ lower than that of rooms with aluminum doors and windows, and 8-15 ℃ higher in different areas in winter.

5. Good sound insulation performance: plastic steel doors and windows with insulating glass and good sealing have excellent sound insulation performance Sound insulation has become the main condition for choosing doors and windows, especially in houses in downtown areas. Plastic steel doors and windows are assembled by welding process and closed multi cavity structure, which has an obvious shielding effect on noise.

With the wide use of plastic steel profiles, some shortcomings are also exposed. Most of the inferior plastic steel profiles in China use lead salt stabilizer, and the lead content of the finished products is between 0.6% - 1.2%. Lead is a substance harmful to human body. When inferior profiles are aged, lead containing dust will be precipitated. After long-term exposure, the lead content in blood will exceed the standard, and even lead poisoning. The imported calcium zinc and organotin formulations have solved the problem of lead in the products, but they have not been applied on a large scale due to price reasons and immature technology.
