Plastic doors and windows profiles

Plastic doors and windows profiles

Answer:

The overall quality of plastic doors and windows by the quality of hardware accessories and installation of a great impact, because the domestic enterprises PVC plastic doors and windows profile profile shape and size are not the same, hardware accessories can not be unified, so the production of each variety of parts Can not be large, it is difficult to form a scale effect, in addition, due to the overall level of consumption of domestic doors and windows is still very low, limiting the price of PVC plastic doors and windows, PVC plastic doors and windows hardware accessories prices are too low, causing manufacturers to meet the market had to reduce Cost and make cheaper cheap hardware accessories. Fortunately, the new standards for plastic window hardware is being developed, hoping to standardize the hardware market. Excellent hardware accessories, can improve the overall performance of the window, such as flat window using multi-point locking than a single point of locking the sealing and wind pressure performance is much higher, the use of corner hinge or adjustable hinge its performance It is much stronger than ordinary type or saddle type hinge, it can effectively prevent fan sagging phenomenon. In addition, the use of silicified and the middle of the taps with the top of the top coat is much higher than the ordinary.
The inherent quality of the profile and its reasonable structural design are the prerequisites for the manufacture of high-performance plastic windows. First of all, there must be good formula and high-quality raw materials and advanced production technology to ensure the quality of profiles. In addition from the structure of the profile of a single cavity and multi-cavity PVC plastic profiles, the cavity can be designed ribs, ribs, boss, etc., can be divided into two cavities cavity, three chamber or multi cavity, Can be better from the role of thermal insulation, on the other hand can make the cavity have different purposes, and some used to fix the rigidity of the steel lining, and some used to set the drainage chamber, and some internal ribs can be prevented Profile deformation, the inner ribs can improve the rigidity of the profile, increase the inertia moment of profiles, and improve the impact resistance of 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.
