What is a plastic window?

Question 1: What are the advantages of plastic steel windows and the characteristics of plastic steel doors and windows?

1. What are plastic steel doors and windows?

Plastic steel doors and windows are made of polyvinyl chloride (PVC) resin as the main raw material steel, with a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers and so on. Through extrusion molding, then through cutting, welding or threaded connection, the door and window sash is made, and it is equipped with sealing strip, top, hardware and so on. At the same time, in order to enhance the rigidity of the profile, it is necessary to fill the cavity of the profile with steel lining (reinforcing ribs), and the doors and windows made by this method are called.

At present, there are many kinds of plastic steel doors and windows, which are classified according to the opening methods: casement windows, casement doors, sliding windows, sliding doors, fixed windows, rotating windows and so on.

Classification by structure: single-layer glass and double-layer glass doors and windows.

Classification by color: monochrome (white or color) and bicolor (* * * extrusion, film covering or spraying).

Second, the performance and characteristics of plastic steel doors and windows

1. Heat insulation and energy saving

The multi-cavity structure of plastic-steel profile has good thermal insulation performance and extremely low heat transfer coefficient, which is only 1/4.5 for steel lining and 1/8 for aluminum. Its economic and social benefits are enormous.

2. Air tightness

Plastic steel doors and windows are equipped with rubber sealing strips and tops at all gaps, so their air tightness is much higher than that of aluminum alloy doors and windows. However, the air tightness of the plastic-steel casement window is higher than that of the sliding window. Under normal circumstances, the air tightness of casement windows can reach Grade 4, and that of sliding windows can reach Grade 3.

3. Impermeability

Due to the unique multi-cavity structure of plastic-steel profiles, they all have independent drainage cavities, so the accumulated water in the frame and fan can be effectively discharged. The water tightness of plastic-steel casement window is much higher than that of sliding window. Generally speaking, the water tightness of casement windows can reach five levels, and sliding windows can reach three to four levels.

4. Wind pressure resistance

In an independent plastic-steel cavity, a steel lining with the thickness of 1.2-3 mm can be added, and the thickness and profile series of reinforcing ribs can be selected according to local wind pressure, building height, hole size and window design to ensure the requirements of buildings for doors and windows. General high-rise buildings can choose large-section sliding windows or internal casement windows, and the wind pressure intensity can reach more than six degrees. Low-rise buildings can choose external casement windows or small-section sliding windows, and the wind pressure intensity is generally Grade III.

5. Sound insulation

Plastic steel profiles have good sound insulation effect, such as double-layer glass structure, which is ideal, especially suitable for places with serious noise interference in downtown areas, such as hospitals, schools, hotels and office buildings.

6. Corrosion resistance

Plastic-steel profiles have unique formula and good corrosion resistance, so the corrosion resistance of plastic-steel doors and windows mainly depends on the choice of hardware, such as anti-corrosion hardware and stainless steel, and their service life is about 10 times that of steel windows.

7. Weather resistance

The plastic-steel profile adopts a unique formula to improve its cold resistance. Plastic steel doors and windows can be used in the environment with large temperature difference (-50℃ ~ 70℃) for a long time, and there will be no deterioration, aging and embrittlement under the scorching sun and humidity. The earliest plastic steel doors and windows have been used for 30 years, and their materials are as good as ever. According to this calculation, the service life of plastic steel doors and windows can reach more than 50 years under normal circumstances.

8. Fire resistance

Plastic steel doors and windows are non-combustible, non-combustion-supporting, self-extinguishing, safe and reliable. The oxygen index detected by Liaoning Provincial Fire Equipment Product Quality Supervision and Inspection Station is 42.3, which meets the requirement that the oxygen index specified in GB 88 14- 1988 "U-PVC Profile for Door and Window Frames" is not lower than 38 degrees.

9. Thermal insulation

The plastic-steel profiles used for plastic-steel doors and windows are excellent electrical insulating steel, which is non-conductive and has a high safety factor.

10. The finished product has high dimensional accuracy and does not deform.

Plastic-steel profiles have uniform lattice and smooth surface, which is easy to process and cut without special surface treatment. After welding, the length, width and diagonal tolerance of the finished product can be controlled within 2mm. The machining accuracy is high, and the welding angle strength can reach above 3000N N n. At the same time, the solder joint is cleaned and the welding burr is removed, and the surface of the solder joint of the profile is smooth and beautiful.

1 1. Easy to protect.

Plastic-steel doors and windows will not be eroded, nor will they turn yellow and fade, nor will they be affected by dust, cement and adhesives, so they need little maintenance. When they are dirty, any detergent can be used. After cleaning, they will be as white as before.

12. anti-theft

The glass beads of plastic steel doors and windows are all facing indoors, and broken glass is easy to replace. Plastic steel profiles have high strength and toughness, are not easy to be damaged, and have good anti-theft performance.

13. Moderate price: Compared with aluminum windows, wooden windows and steel windows with the same performance, windows with plastic steel doors and windows are more economical.

Plastic steel doors and windows have excellent physical properties and can be widely used in places with harsh environment such as strong wind, heavy rain, high heat, cold and corrosive gases. They are ideal and reliable buildings ... ";

Question 2: What material is plastic steel? Plastic-steel profiles are made of U-PVC, the full name of which is unplasticized PVC.

Question 3: What is a plastic steel window? What is a plastic steel window? As the name implies, plastic-steel doors and windows are doors and windows made of plastic box steel, mainly made of PVC profiles and steel bars with hardware components, which have the advantages of good heat insulation and sound insulation and are widely used in the north.

Question 4: What is plastic steel? Plastic 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 into China from 1983, and began to be 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 to the cavity to enhance the firmness of doors and windows, so plastic doors and windows made of steel 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: 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 threaded to make door and window sash, equipped with sealing strip, top, hardware, etc. At the same time, in order to enhance the rigidity of profile, it is necessary to fill steel lining (reinforcing rib) in the cavity of profile exceeding a certain length.

Question 6: What is the main structure of the plastic steel window? General plastic steel doors and windows mainly include: PVC profiles, screens, lining steel, hardware, tops, rubber strip and various accessories and other accessories.

1, screen window:

It can be divided into aluminum alloy frame and plastic steel frame. Screen is the main functional component of screen window, which mainly includes Bai Gang yarn, nylon yarn, steel wire yarn, plastic-sprayed yarn and so on. At present, Bai Gang and nylon yarn are widely used in the market, and the price difference is several times. In addition to the service life, other indicators of gauze are mesh size, that is, eye size, high mesh size, thin eyes and good anti-mosquito effect. The quality of screen silk is generally scratched, and more than 20 meshes are qualified.

2, lining steel:

It can be divided into zinc plating and corrosion protection. According to the national standard, galvanized lining steel should be adopted, and the size, thickness and various physical and chemical properties of lining steel should also meet the national standard.

3. Top:

There are two kinds of silicified and non-silicified, which have good weather resistance, long service life, easy aging without silicified, hair loss and hair loss, and the price difference is several times.

4. rubber strip:

It can be basically divided into reclaimed rubber and raw rubber. The reclaimed rubber is not aging-resistant after being used many times, and its texture is hard, which leads to short arc time.

Question 7: What is the glass of plastic steel window? Window glass refers to the open upper part and unopened fixed glass. Traditionally, it is called this, mainly for old wooden windows, which have been used until now. It is necessary to distinguish it from the open part. If there is a fixed glass below, it is called the next lamp.

Question 8: What's the difference between steel-plastic window and plastic-steel window?

Steel plastic and plastic steel should be the same thing, because its hollow structure has better thermal insulation performance than steel, so it is widely used in thermal insulation doors and windows of new buildings.

Question 9: What kind of plastic steel window is good? Now, you should think more about replacing doors and windows. 70% heat is lost from doors and windows. Choosing a good door and window will save you a lot of money, and the first investment will be made up in time, just like energy-saving light bulbs. If the budget is not a problem, I recommend Xu Ge, Kaus and Vicat. They are all German doors and windows.

The main consideration is how thick the visible wall of plastic steel is, what hardware is used, what company provides glass, and the level of installation workers.

Question 10: What is plastic steel? Plastic steel is the abbreviation of plastic steel profile, and its main chemical composition is PVC, so it is also called PVC profile. The material has excellent performance, convenient processing and wide application. Because of its excellent physical properties such as rigidity, elasticity, corrosion resistance and aging resistance, it is usually used as a good substitute for non-ferrous metals such as copper, zinc and aluminum.
