ã€China Aluminum Industry Network】 1. Doing a Good Job in the Installation of Aluminum Alloy Doors and Windows The impermeability of aluminum alloy doors and windows is mainly reflected in the production, installation, inspection and acceptance of aluminum alloy doors and windows, and civil engineering cooperation, creating no leakage. The aluminum alloy doors and windows impervious program at the same time clear the choice of materials: Aluminum alloy profiles selected Wuxi Fairview company's profiles, sliding door selection 828 series profiles (in order to increase wind resistance capacity, increase light Kai), flat doors and windows selection 50 Series profiles.
The foaming agent is selected from Batima products. Silicone is made of Dow Corning Neutral Silica Gel.
When the aluminum alloy doors and windows are impervious in production, field inspections are conducted on the actual hole size and painting size, and the production size is determined on the premise of the specification. The aluminum alloy doors and windows finished in accordance with the specification of aluminum alloy doors and windows anti-seepage acceptance.
Before the installation, aluminum alloy door and window openings were examined one by one, and written information was provided to the civil painting team. The plaster size of the opening and the gap of aluminum alloy door and window frames were uniformly controlled at about 15 mm. Impermeability of aluminum alloy doors and windows Our approach is: When the external wall to complete the layout of the brick, according to the layout of the tile to determine the aluminum alloy doors and windows of the horizontal line, vertical line and in and out of the line, and then check the size of the hole.
Second, the installation of aluminum alloy doors and windows Aluminum alloy doors and windows frame installation construction content includes: 1, aluminum alloy doors, window frames into the field to check the horizontal line, draw vertical lines, in and out of the line, window frames, hole mouth alignment, clean the hole. 2. Tilted wooden wedge fixed window frame, correction, fixed nail iron nail, check. 3, mortar or fine seal iron feet. 4, after the iron foot dry mortar, remove the wooden wedge, powder outdoor hole. 5, injection foaming agent, outdoor before relying on silicone. 6, the window frame mortar sealing, compaction, receive the pulp. 7. Play silicone on the inside of the door and window frame, and play second-degree silicone on the outside. 8, install the frame fan. After installation, concealed acceptance of the connector and foaming agent. The actual measurement of the verticality of the door and window diagonals, so that the installation quality meets the requirements.
In the installation of aluminum alloy doors and windows, the following procedures can be generally accepted for impermeability inspection of aluminum alloy doors and windows: acceptance before the installation of doors and windows openings, installation of doors and windows frames, acceptance doors and windows frames, playing expansion agent, outdoor frontal silica, acceptance expansion agent, silicone , To pay for the construction of plastering holes, acceptance holes, painting, playing silicone, acceptance of silicone, door and window installation, overall acceptance of doors and windows, and watering test. After all the doors and windows are installed, spray tests are also carried out to check the leakage of doors and windows.
Key aluminum alloy doors and windows anti-seepage process construction process. The construction of foaming agents and silicones is the focus.
After the installation of aluminum doors and windows frames, in order to prevent the installation of aluminum doors and windows anti-seepage aluminum doors and windows from the outside to the room around the gap between the box body and then injection foaming agent, clear the construction of the hole before the construction of the platform and both sides of rubbish, dust, cement slag Block, use skin tiger to blow dust off. (If the gap around the frame is >15mm, mortar should be used first, so that the gap around the frame is <15mm). When the foaming agent is used, the outside foaming agent is pressed for 10 minutes and then pressed by hand (with the outer frame flat), and the outdoor side is relied on the frontal silicone. Silica gel inside the door and window frame, outdoor second-degree silica gel. Pay attention to the protection of the surrounding when playing silicone (covering the window frame and wall with adhesive tape, when the silica gel is dry on the surface, and then tear it off), then connect straight and smooth, with arc.
Third, civil construction and construction content In order to better install the doors and windows, we must do a good job of aluminum alloy doors and windows and civil construction cooperation.
Our approach is: clarify civil works and construction content, so that the cooperation with targeted, the main civil construction with the following content: 1. Civil construction according to design requirements to ensure the accuracy of the size of doors and windows openings, hole width, height error pick window 5mm, flat window ± 10mm, hole diagonal error 5mm. Before the installation of windows and doors, cooperate with inspection dimensions and three lines (vertical line, horizontal line, in-out line). At the same time, it is necessary to inspect the entire vertical door and window frame in the horizontal and vertical lines to meet the requirements of the design drawings.
When installing the window, the vertical hanging line is firstly positioned to ensure that the lower window of the entire facade is in a straight line. 2. After the doors and windows are installed and the foaming agent for doors and windows is constructed, the iron feet of the doors and windows shall be buried in time. After anchoring the foot with mortar or mortar, dry it and remove the slant wood. The window sills shall be poured with C20 fines and then painted. In the construction of anti-seepage of aluminum alloy doors and windows, it is necessary to ensure the stucco quality around the opening. The level of beam crossing is controlled at 1.5%, the total length is not more than 3mm, and the verticality of the hole is controlled at 1.5%. After painting, pay attention to strengthening conservation, prevent paint cracks and seepage.
LED is the abbreviation of Light-Emitting Diode. It is made of semiconductor materials. It has a positive pole and a negative pole. When DC is applied to its positive and negative poles, it will emit light. From 1907 to 1993, LED has experienced 86 years of history. The application of LED technology is generally divided into visual and non-visual categories. The application of visual category includes LED lighting technology, and the non-visual category includes plant photosynthesis and medical care.
LED process:
The whole production process of LED Lamp Beads is divided into epitaxial chip production, chip production, and lamp bead packaging. The whole process reflects the manufacturing technology level of modern electronic industry. The manufacturing of LED is a combination of multiple technologies and a product with high technology content. The knowledge of LED for lighting purposes also needs to know how LED lamp beads are produced.
LED epitaxial wafer production process:
LED epitaxial wafer growth technology mainly uses organic metal chemical phase deposition (MOCVD) to produce synthetic materials with semiconductor characteristics, which is the raw material for manufacturing LED chips
