Question 2: What is the material of plastic steel, ok? Plastic steel is a kind of plastic steel with excellent performance, which has hardness and strength similar to that of gold, and has excellent tensile strength, bending strength, fatigue resistance, wear resistance and aging resistance. Well-known brand Germany Lede Flying Wing is used to make mattresses.
Question 3: What is the material of plastic steel? Plastic steel profiles are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers and so on. And being squeezed out.
The main raw material is polyvinyl chloride (which can be understood as plastic), which is a thermoplastic resin polymerized by vinyl chloride under the action of initiator.
Question 4: What is plastic steel? Plastic and steel frame
Refers to PVC profiles used for making doors and windows, which appeared in Germany as early as the end of 1950s, and was introduced to China from 1983, and was popularized and applied in the end of 1990s. Because the strength of doors and windows processed by PVC profiles is not enough, steel is usually added into the cavity to enhance the firmness of doors and windows, so plastic doors and windows made of steel added into profiles are usually called plastic steel doors and windows. With the wide use of plastic steel doors and windows, PVC profiles used to make plastic steel doors and windows are customarily called plastic steel profiles.
Question 5: Who knows what plastic steel is? Thank you, and God bless you. Plastic steel is POM (Polyoxymethylene), which is a new building material widely used in recent years. The material has excellent performance, convenient processing and wide application. It is characterized by excellent antifriction, wear resistance, fatigue resistance and drug resistance, rigidity, elasticity and dimensional stability. It is the best substitute for non-ferrous metals such as copper, zinc and aluminum. It is mainly used for sliding doors, windows, guardrails, pipes and ceiling materials in building construction. As soon as POM appeared, it was quickly applied to zippers, achieving a breakthrough in zipper materials. However, with the continuous improvement of people's requirements for zippers, the performance of POM is gradually unable to meet. Modification of polyoxymethylene is the most effective method. By adding nano-inorganic materials into POM, its mechanical properties, rigidity and thermal deformation temperature are improved, thus improving the quality and grade of products. At the same time, the addition of nano-materials can also prevent the zipper teeth from becoming moldy. The technical level of the project is at the international leading level and will fill the gap at home and abroad. This project is mainly used for zippers, auto parts and so on. The project is being implemented.
Question 6: What is the material of plastic steel doors and windows? Plastic steel doors and windows are made of polychloroprene (UPVC) resin and a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. , extruded into profiles, and then cut, welded or screwed to make door and window sash, equipped with sealing strip, top, hardware, etc. At the same time, in order to enhance the rigidity of the profile, the inner cavity of the profile exceeding a certain length needs to be filled with steel lining (reinforcing ribs).
*** c should be ok, but the price is not clear.
Question 7: What material is the plastic steel door? It should be very easy to use and has good corrosion resistance. But it should be genuine, not fake. It can really be used for about 20 years, and it is environmentally friendly. If it is fake for about 3 years, there are many harmful substances. If the door is made according to the national standard, the price will probably be around 450 yuan.
Question 8: I don't know the material of plastic-steel window profile. I wonder how long those two upstairs have called themselves experts. From the national market, the top three domestic brands are Shide, Conch and Cai Zhong. I worked in Shide three years ago, and now I work in Cai Zhong. I don't know the profile brand mentioned by the landlord. At the beginning of this year, Shide's new 7-letter system really got 278 in Building Materials City. If this is not the profile mentioned by the landlord, then the price of 280 is understandable. In addition, there is such a saying about the grade of profiles. In GB 88 14-2004, profiles are divided into ABC three categories according to the wall thickness of main profiles. According to the regulation of "minimum thickness of visible surface/minimum thickness of invisible surface", the wall thickness of Class A profile is required to be 2.8/2.5mm, that of Class B profile is required to be 2.5/2.0mm, and that of Class C material is not required. The mainstream national standard profiles on the market are all B-type. Besides, I will answer questions on the second floor. From the national market, Jin Peng profile is also a good profile, ranking fourth, and there is little controversy at present. If you have any questions, please contact Tencent number 250593527.
Question 9: Is "plastic steel" steel? What is its composition? What is plastic steel?
The so-called plastic steel is the door and window material extruded with PVC-U as the main component, which is what we call plastic. In the process of processing, in order to prevent the deformation of the profile, the matching lining steel is added to the profile. Plastic plus steel/plastic steel for short.
Because plastics are used as raw materials, their assembly is mainly high temperature welding. The temperature is between 220 and 260 degrees.
The earliest welding equipment was manual operation and single-angle welding, which was easy to make mistakes. At present, most manufacturers introduce advanced processing equipment. Even some small processing plants have two computer-controlled welding machines. There is no problem in the processing, assembly and molding of plastic steel.
There are several reasons why small processing plants are cheap: 1. Small business area, less tax, or even no tax. 2。 There are few workers, mainly family members. 3。 The key point is "civet cats for princes" and take it seriously.
Common configuration files in the market are: Shide/Conch/some unknown brands. This is why the gap between those unknown brands and Shide/Conch is very simple. Tear off the label protective film of the poor brand and re-attach the protective film of Conch/Shide brand, and you're done! Identification method: look at the anti-counterfeiting code on the introduction/look at the smoothness of the material/it is best to take some real brand samples when ordering/.
4。 Steel lining/standard matching is required. The thickness is between 12-22. The identification method is to take the weight of the molding window as much as possible. A frame of 1500* 1000 weighs about 30 kg.
Question 10: What material is the plastic door made of? Literally, it is made of plastic and steel.
