>>> How to install aluminum alloy doors and windows?
Aluminum-plastic doors and windows are widely used in the current homes. In the actual installation and construction, if you do not pay attention to some details, it will often leave hidden dangers for future use. Now experts are invited to teach you to install it.
Question 1: aluminum alloy doors and windows leaking water
Occasionally, aluminum alloy door and window frames are found leaking water at the joints with the wall, especially in the lower corners of the window. Secondly, water seepage occurs at the splicing section of the composite window.
Corresponding measures: 1. Due to the different coefficients of thermal expansion of the aluminum alloy profile and the wall material, under the influence of temperature, the capillary cracks are likely to occur at the junction between the frame body and the wall body. In order to prevent water seepage at the cracks, the aluminum alloy door and window frame should be elastically connected to the wall body. Before construction, the floating ash, mortar particles and other debris in the joint groove should be removed first, and then the inside and outside of the frame jointed with the wall body should be marked. The sealant is closed, the glue injection should be continuous, do not omit, and the bond should be firm. 2. The exposed connecting screws should also be sealed with a sealant to prevent water leakage.
Question 2: Aluminum alloy doors and windows are not firmly installed, the overall stiffness is poor
The aluminum alloy door and window frame cracks at the junction with the wall; when the door is pushed or opened and closed, the frame fan shakes; when the air pressure is applied or pushed by hand, the window frame is deformed and shaken, giving a sense of insecurity.
Preventive measures: 1. Aluminum alloy doors and windows should be based on the size of doors and windows, installation height, choose the right profile. 2. When the door and window frame are installed, reliable connection shall be made between the connector and the wall. The connecting piece shall be made of thin steel plate with a thickness of not less than 1.5mm and be treated with antiseptic. The connection method generally uses expansion bolts and injection needles embedded in the wall. 3. After the aluminum alloy doors and windows are installed, they can be used to push the door and window frame for inspection. If they are found to be shaken or deformed, they should be reinforced.
Question 3: The glass installation is not facing the right
In recent years, coated glass, embossed glass, and frosted glass have been increasingly used as decoration materials in home improvement and decoration. However, there are cases where installation is not performed in accordance with regulations, which affects light reflection and decoration effects.
Prevention measures: 1. Pay attention to the orientation of the glass installation. When embossed glass and frosted glass are installed, the pattern of the embossed glass shall be directed outdoors. The frosted surface of the frosted glass shall be indoors. 2. The coated glass should be installed in the outermost layer, and the coated layer of single coated glass should face the room. 3. When cutting glass, no nicks or squints should appear on the edges.

Talc (Talc) is a layered silicate which is a hydrate.
Theory of MgO style chemical formula 3, 4 - SiO2, H2O, and the theory of chemical composition as follows: 31.68% MgO style SiO2 H2O 63.47% to 4.75%, the natural quality of pure talc ore are very few, most associated with other mineral impurities, common associated minerals include chlorite, serpentine, magnesite, tremolite, dolomite, etc.
Talc is often white, light green, microstrip pink, light grey, with impurities the more the color is deeper, even dark grey, black.
Monoclinic crystal system, ore presents flaky, fibrous and dense.
Pearly luster or oily luster, the heating effect of the talc are substantially heated, lose adsorbed water during 120 ~ 200 ℃, 600 ℃ when begin to lose part of the structure of water, until 1050 when the structure all the water out.
The best way to identify talc is to conduct X-ray diffraction analysis or thermal analysis.
