Plastic steel profiles how to open the mouth of the best illustration and the formula there are cross-port V to answer to a comprehensive ah
Plastic profiles open V mouth has a special V mouth saw, with a manual cutting machine are not allowed, angle, V port depth can not be determined.
What belongs to plastic profiles
Plastic Profile A: Impact modifier Plastic profiles, such as without impact modifier, plastic profiles will be very brittle, slightly collision, easy to break. Plastic profiles used in the production of anti-impact agent modifier mainly by the following three categories: chlorinated polyethylene, polyacrylates, ethylene - vinyl acetate copolymer. Plastic profile additive two: heat stabilizer Plastic profile is a thermosensitive plastic, so in the production and processing of plastic profiles, heat stabilizer is essential. The metal salt in the heat stabilizer absorbs the HCL from the PVC, so it can delay the decomposition rate of the plastic and prolong the decomposition time. The most commonly used in the production of plastic profiles is the compound lead salt, which has high thermal stability and low cost. Plastic profile additives three: lubricant The main role of the lubricant is to reduce the polymer and processing equipment and polymer molecules between the internal friction between the friction caused by excessive heat caused by resin degradation, improve the efficiency of heat stabilizer.
The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
Plastic can not be used mainly to see its ability to withstand wind pressure can not meet the requirements, and the state did not force the request. At present, only Qinghai is limited to plastic steel, it is because the UV is relatively strong in Qinghai, steel weather resistance is not good aluminum. In fact, as early as ten years ago, steel doors and windows can be used in the tall buildings in Xiamen, indicating the use of absolutely no problem, provided that your doors and windows must be reasonable design, through the local fifty years once the wind. But also in the doors and windows production and installation process to comply with the specification.
Specification for steel profiles
At present, the smallest domestic steel profile section for the 60 series, a screw-connected window called steel-plastic composite doors and windows,
Plastic steel window profile specifications models which
Push-pull series of models are: 75,80,88,95; flat open series models are: 60,66,70,106.
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.
Is the powder produced when the crushed plastic is crushed?
The use of alloy steel blade, long life; the same time, the separation of the design, easy maintenance and cleaning, and a double structure, equipped with sound insulation material, the noise is very low, knife shaft seat after a rigorous balance test, There are four rounds, easy to move.
China 's top ten brands of steel profiles in 2014
In the financial financial steel doors and windows is a national key high-tech enterprises, is the industry's well-known brands, the national one of the top ten brands of steel doors and windows, it has Zhejiang Zhongcai profile company production. A large multinational company headquartered in Germany. It is the international profile of the North New North new steel doors and windows is China's largest new building materials group. The company has created more than 30 years of history, it is also well-known trademarks in China. The market occupies a certain proportion.
