Plastic windows were first developed in the late 1950s by West Germany and began production in 1959. The original plastic windows were all simple and rough. With the worldwide energy crisis in 1972, plastic windows with good energy-saving effects in the early 1970s were used extensively, which also promoted the improvement of profile production technology. The performance is improving day by day, from the original single-cavity profile to three-cavity and four-cavity profiles, which also promoted the development of plastic doors and windows in Europe and Asia. So what should you pay attention to when installing it?
First, the material requirements
1, plastic steel window frame, fan
According to the design requirements, different product series are selected, and the surface of the product is not allowed to have traces of stains and bumps.
2, accessories
Stainless steel screws, pulley blocks, locks, nylon brushes, etc.
3, other
Connector, rubber strip, padding, plastic tape, glass glue, wooden wedge, etc.
4, glass
Hollow white flat glass.
Second, construction tools
Aluminum level, nail gun, electric drill, rubber cylinder, glass suction hand, tamper and so on.
Third, the construction points
1. The installation position of plastic steel window should be regular, square and firm, and there should be no warping, cornering and loosening.
2. For the windows and fans that have entered the market, they should be stacked neatly according to different specifications and types, and the bottom layer should be padded. At the same time, protective measures should be taken to prevent deformation caused by being crushed or collided during storage.
3. Before the installation of the plastic steel window frame, in addition to the side of the ash, the other three sides need to be wrapped with plastic adhesive paper to prevent contamination.
4. The size of the hole for installing the plastic steel window frame should be correct. The gap between the upper and lower frames should be 15~18mm, and the thickness of the ash should be 20~30mm on both sides.
5. When installing the plastic steel window sash, the hardware accessories selected must be matched. It is necessary to make the window open and close after installation.
6. Sealing strips should be installed around the window sash and the metal frame materials should not be in direct contact with each other.
7. Pay attention to the protection of finished products. The window frame after installation must strictly avoid the displacement and damage caused by car collision and object collision.
Fourth, the operation method
Different types of plastic-steel windows differ slightly in the specific construction of the installation, but the basic installation procedures are roughly the same.
1, pay off
The window frame is generally a rear plug, and the size of the opening is left according to the design during construction of the structure. The size of the sash processing should be slightly smaller than the size of the opening, and the gap between the sash and the structure should be determined according to different decorative materials. If the inner and outer walls are plastered, the thickness of the plaster layer is generally about 2 cm, so the actual outer edge size of the window frame is less than 2 cm on each side. If the finishing layer is a kind of plate such as marble or granite, the thickness of the inlay structure is generally about 5 cm, so the outer edge size of the window frame should be about 5 cm smaller than each side of the hole size. In summary, the finish layer is perpendicular to the door and window frame, and the intersection should be the finish layer that exactly matches the edge of the window frame, without the finish layer covering the window frame.
Titanium alloy is a class of metallic materials widely used in various high-performance applications. It is a combination of titanium with other elements, such as aluminum, nickel, molybdenum, and vanadium, to enhance the properties of pure titanium.
One of the key advantages of titanium alloys is their high strength-to-weight ratio. They are significantly lighter than steel while being just as strong, making them ideal for aircraft, missiles, and spacecraft. Moreover, titanium alloys possess excellent corrosion resistance, which makes them highly suitable for marine, offshore, and chemical processing environments.
In addition, titanium alloys exhibit good biocompatibility, which makes them suitable for medical implants such as artificial joints, dental implants, and pacemaker cases. They also have high fatigue resistance, low thermal expansion coefficient, and excellent weldability.
Overall, titanium alloys have become an essential material in many industries, including aerospace, marine and offshore engineering, chemical processing, biomedical engineering, and sports equipment. As research continues to advance, it is expected that more innovations in the field of titanium alloys will arise, paving the way for even safer and more efficient applications.
