Plastic doors and windows and plastic doors and windows have anything to do
- According to the characteristics of profiles, the profiles are roughly divided into European and American two.
European doors and windows of its characteristics are: profile formulations still use the traditional lead salt heat stabilizer, a small number of countries and enterprises began to use environmentally friendly organic tin heat stabilizer; main section of the profile profile is generally designed for three or four main chamber, The total number of chambers to 6 to 8, wall thickness is generally 2.5 ~ 3.0mm.
Doors and windows with fan-fan frame structure, fan section larger, with pulley, can be removed; built-in glass, dry mosaic; window open in the foreign under the hanging window-based, a small amount of sliding window.s
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
Will the model of steel profiles (such as 88-type extrusion profiles, 80 extrusion profiles) is based on what to develop ah
- Strictly speaking, refers to the width of the bottom of the window frame profile. 88 is that the bottom of the frame width of 88 mm. And some profiles are not absolutely accurate, take the approximate values
Plastic steel window profile material
- I do not know upstairs two self-proclaimed expert, in the line and do so long. According to the national market, the top three domestic brands is nothing but Shide, Conch, Finance, three years ago I work in Shide, and now I work in the financial. I do not know the landlord said the profile of the brand, but the beginning of this year Shide new 7 sealed series did in the building materials city speculation to the two hundred and seventy-eight. If the landlord said the profile is not this, then the 280 price is high and understandable. In addition to the grade of the profile is this argument, GB 8814-2004 according to the thickness of the main profile of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" A type of material requirements wall thickness 2.8 / 2.5mm, B type requirements of wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B. In addition, I answered the second floor of the problem, Jinpeng profiles according to the national market is also a good profile, ranked fourth in the current controversy is not large.s
PVC plastic profiles dip in the seam, how to deal with seamless docking
- Fill too much for the current market price of profiles is low, and the pattern of rising raw material prices, profile manufacturers are to reduce the cost of the article, the formal profile manufacturers through the optimal combination of formula is not to reduce the quality of the premise, Cost; some manufacturers are in reducing costs while also reducing the quality of products. As a result of the ingredients of the formula, the most direct and effective way is to increase the filler, in the PVC-U plastic profile commonly used filler for the calcium carbonate. Most of the previous formula system is to add heavy calcium, the purpose is to increase the rigidity and reduce costs, but the calcium particles because of their irregular shape and relatively thick particle size and PVC resin body compatibility is poor, so the number of its added Low, and the number of copies will increase the color and appearance of the impact. Now with the development of technology, most of the use of ultra-fine light activated calcium carbonate, and even nano-calcium carbonate, which not only play a role in increasing rigidity and filling, but also has the role of modification, but its filling is not Infinitely, the proportion should be controlled. Now some manufacturers in order to reduce the cost of calcium carbonate added to 20-50 copies, which greatly reduces the physical and mechanical properties of profiles, resulting in this chapter referred to the phenomenon of brittle profile.s
China 's top ten brands of steel profiles in 2014
- 1. Conch Conch steel doors and windows profiles are Anhui Conch Group under a building materials business, Conch steel doors and windows is a national high-tech enterprises, is the top ten steel doors and windows brand ranking first. Conch Group in the country to build a branch. Conch Group is also a state-owned enterprise. But fake more
2. Shide in the steel doors and windows industry has a large Chinese market, it is controlled by the Dalian Shide Group. Northern market share is high but 14 years down the road.
3. Huaihai China Famous Brand. Domestic large-scale production enterprises in the few, specialized in the production of independent legal entities. National steel doors and windows one of the top ten brands, East China market share is high, favored by consumers.
4. Kemei Te Ke US special steel doors and windows is Sichuan Kemei Te Group's brand, its in Sichuan, Anhui, East China has a profile production base in the southwest region occupies a considerable market, favored by consumers.s
Plastic doors and windows profiles
- 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.s
Steel windows and aluminum windows compare which is more expensive
- Wind pressure strength and watertightness:
Plastic windows due to the strength and rigidity of the material is low, although through the processing of steel to enhance, but its wind pressure and watertight performance than the aluminum window about two levels. Moreover, due to the steel window steel lining steel is not in its profile cavity angle into a complete frame system, window frame, fan four corners and T-shaped plastic welding angle strength is relatively low, according to the end of 1998 Shanghai enterprises inspection 425 Batch steel window three examples of the situation after the serious analysis of the "plastic window in the high - rise buildings should be used with caution.s
