Bathroom plastic door with what material to do
- The plastic material of the bathroom is PVC
Plastic doors and windows (Plastic doors and windows), that is made of U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features.
According to the material can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows.s
What is the steel profile?
- The profile is still visible when the window is still visibles
How to identify the installation of plastic or plastic
- Plastic steel because there are iron, so use the magnet to identify.
Another: steel easy to change line, now mostly switch to color steel or better.s
Is not aluminum alloy better than steel?
- Plastic shortcomings: Each product has its shortcomings, with the extensive use of steel profiles, some shortcomings also will be exposed. China's steel profiles most of the poor quality of the use of lead salt stabilizer, finished lead content between 0.6% -1.2%. Lead is a harmful substance to the human body, when the poor quality of aging, will precipitate lead dust, long-term exposure will lead to excessive lead in the blood, and even lead poisoning. The recent introduction of calcium and zinc and organic tin solution to solve the product contains Lead problems, but because of price reasons and technology immature, there is no large-scale application.s
Plastic doors and windows and plastic windows do not like?
- Glass fiber reinforced plastic (FRP) doors and windows
1) abroad to alkali-free glass fiber reinforced, the product surface finish is better, no need to deal with the system can be used directly to the window. Domestic self-developed glass fiber reinforced plastic doors and windows profiles generally with alkali glass fiber reinforced, the surface of the profile after grinding, available electrostatic powder coating, surface coating and other technical processes, access to a variety of colors or texture of the decorative effect. The following are the same as the "
2) Do not use high-alkali glass fiber made of profiles. The following are the same as the "
3) FRP doors and windows profiles have a high longitudinal strength, under normal circumstances, you can not enhance the steel. But the doors and windows size is too large or high wind pressure requirements, should be based on the use of requirements to determine the enhanced approach. The transverse strength of the profile is low. Fiberglass doors and windows frame for the assembly of the turret, the joints need to use sealant seal to prevent leakage of the gap.s
Plastic doors and windows profiles
- Plastic doors and windows with its good insulation, insulation, sound insulation and corrosion resistance to become steel and wood windows of the alternatives, but because of the market is not mature, raw material prices soared and the price of the profile is soaring, making a lot of profiles manufacturers Not to sacrifice the quality of the material to reduce costs, in the profile by adding a lot of calcium carbonate or the use of low-cost raw materials additives, plastic window with poor quality hardware accessories, ultra-thin ribs plus rough manufacturing process, so low-performance products into After the market, to the user and the industry has brought a great negative impact, the long run, will repeat the sixties and seventies of the same mistakes.s
PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages?
- PE is polyethylene, this product is light weight, easy processing, the screw and the barrel is not too high requirements, processing temperature is wide, but the hardness is not PVC and ABS good, chemical resistance, some places as PVC.s
Fence material outside the plastic inside is iron or steel this material called
- Plastic steel profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., by extrusion of the profile.s
