PVC plastic door & Window Basic Introduction
igelite doors and windows use polyvinyl chloride (PVC) resin as the main raw material, adding a certain proportion of stabilizer, modifier, filler, UV absorber and other additives formula and modification, after extruder extrusion molding into hollow profile of various fault structures, after fixed length cutting, steel profile reinforcement is lined in its inner cavity, and then welded into door and window frames and fans by hot melt welding machine, and the sealing strip is assembled, brush strips, glass, hardware accessories, etc. constitute finished doors and windows. In order to increase the rigidity of PVC plastic hollow profile, the inner cavity is reinforced by human-shaped steel to form a plastic-steel structure, so it is also called plastic-steel doors and windows.
PVC is the abbreviation of polyvinyl chloride: "RPVC" or "UPVC" is used before "plastic doors and windows", which actually belongs to the same material, that is, "rigid polyvinyl chloride" or "unplasticized polyvinyl chloride".
PVC plastic door & window is a new type of building material, which is more resistant to corrosion than wooden window and copper window, and does not need paint maintenance. Compared with aluminium windows and copper window, it has good heat insulation, sound insulation and sealing performance, and the appearance is gorgeous and colorful, it can be coordinated with various buildings.
The quality of plastic doors and windows is uneven
in recent years, the production and application of plastic doors and windows have developed rapidly and have become one of the leading products in the door and window market. However, there are some bad phenomena in the plastic door and window market, such as vicious price competition, poor quality of product manufacture and installation, low professional and technical level of production and installation personnel, and some products are not tested according to the requirements of national standards, the phenomena such as the deformation of doors and windows, the discoloration of profiles, the damage of hardware and the cracking of sealing strips occur frequently, which affects the overall quality of the project and also brings adverse effects to the development of the plastic doors and windows industry, the profits of the whole industry are becoming thinner.
Judging from the current situation, many small workshop-style plastic doors and windows processing plants are still all over the streets and alleys. The negative situation of poor quality and low price has harmed the overall image of plastic steel doors and windows, the warming of the market needs the continuous improvement of consumer consumption concept, the drive of well-known leading enterprises, the promotion of building energy conservation, and the effective regulation of regulatory agencies.
In view of the quality problems of plastic doors and windows, the state has taken corresponding measures. At present, the engineering construction industry standard "technical regulations for design and assembly of plastic doors and windows" has formed a draft for review and is preparing to report it to the Ministry of Housing and Construction for approval.
Advantages of plastic doors and windows
1. Anti-corrosion, acid resistance, alkali resistance, salt resistance, etc., in damp, salt spray, acid rain, no corrosion, mildew, no moth.
2. The shape and size are stable, not loose or deformed.
3. Long life, can be used normally for about 30 years.
4. It is self-flame retardant, does not burn, has self-extinguishing property, and has high oxygen index, reaching more than 40, which is conducive to fire prevention. Because the oxygen content in the air is about 20%, instrument frame will not burn in the natural environment.
5. Beautiful appearance, strong texture, rich colors, easy to scrub and clean.
6. Light and flexible to use, impact resistant, no impact sound when switching. This is mainly because the sealing materials of doors and windows are elastic materials, such as PVC and EPDM.
7. Basically no maintenance, no paint, and low use cost.
8. Air tightness and water tightness are much better than steel and wood doors and windows, which are generally 2-3 grades higher than them. Air tightness and water tightness can lead to many problems, such as energy loss caused by indoor and outdoor heat exchange, etc.
Disadvantages of plastic doors and windows
due to the low elasticity modulus of materials of PVC material, only about 1/80 of steel, in order to achieve the required material steel degree for windproof pressure resistance of windows, we increase the material cross section and increase its moment of inertia, and add steel lining in the appropriate cavity.
Due to the large cross section of the material, the light blocking area of the material increases, resulting in the whole window Square area being about 5%-11% smaller than copper window and about 4%-9% smaller than aluminum.
Due to the increase of material section, the corresponding weight of material thread also increases, resulting in a higher window cost. When a single glass is installed, it is 30-50% more expensive than copper window, but in some cold areas, compared with double-stage single glass aluminium windows, the cost of PVC windows with single-stage double-layer glass is lower than that of the latter, but the insulation and lighting of PVC windows are much better than that of double-stage aluminium windows. This is also one of the most successful reasons for the promotion of PVC windows in cold areas of our country.
