Q:What belongs to plastic profiles
Plastic profile additives four: processing aids Auxiliaries are mainly developed to improve the performance of plastic molding. Plastic profile processing temperature and decomposition temperature is close, poor mobility, easy to stick in the equipment on the coking, so the production of plastic profiles need to add a certain amount of processing aids to overcome the defects of plastic profiles themselves. Plastic profile additive five: light stabilizer The light stabilizer can inhibit the photooxidation degradation reaction of the polymer by shielding and absorbing ultraviolet rays, quenching and exciting energy to capture free radicals, so as to give the products a good light stabilizing effect and prolong their service life. Plastic profile additives six: filler The filler is a solid additive that is different in composition and structure from plastic, also known as fillers. To improve the physical and mechanical properties of plastic and reduce the cost of plastic has a significant effect and economic value. Plastic profile production formula to add filler, plastic profiles can be heated after the size of the change in the rate of change, increased impact strength, increased rigidity, while also reducing production costs.
Q:What is the steel profile?
Simply put the profile is installed into a window that can still be seen after the outer surface. Such as the large and small faces of the box. While the middle glass trough installed glass and pressed after the invisible, that is non-visible surface.
Q:Specification for steel profiles
Before 50, did not use 40 or 38, 10 years ago I have done spliced steel, and now who is willing to splicing ah. But really want to splice, and now have steel can also be spliced.
Q:Plastic steel window profile material
The layman is so to say that there is no grade steel, on a model, the standard requirement is to look at the three sex. ABC blind Mongolia Yeah, you will be the best, the price is not expensive 280 steel is a foreign brand? The highest price in the country, but 170-280. Who's how good you are. Are generally about 170 on the OK.
Q:How to identify the installation of plastic or plastic
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.
Q:Plastic steel profiles how to open V mouth
Plastic profile V-head saw is mainly used for steel-type 90-degree V-mouth cutting, the internal equipment by the two motors, two pieces of blade. Start the V saw when the two motors at the same time driving into a 90 degree saw blade, the steel profile cutting a 90 degree V port. Saw the saw speed, saw no burr, smooth surface. easy to use. The equipment is running smoothly. High precision. The depth of the V-shaped steel profile is half of the large surface height of the stitch (welding flux).
Q: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.
Q:What is the broken bridge of aluminum? What are the characteristics?
Broken bridge aluminum energy saving and environmental protection: broken bridge aluminum aluminum-plastic composite window at the seams are equipped with multi-channel sealing tops or ternary ethylene rubber tape, air tightness for a level, can give full play to air conditioning, and save energy 50%.
Q: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.
Q:Plastic doors and windows and plastic windows do not like?
According to the material plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows. The following are the same as the " 1, PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. The following are the same as the " 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. The following are the same as the " 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect. In addition, UPVC resin powder is also added to the pigment mixture extrusion of the body dyeing technology. But there are still different views on this technology, it should be particularly careful in the selection, to check the kind of profiles by artificial accelerated aging test after the color changes. It is recommended to coat the color film with the color film to improve its weatherability.
