Brief description of aluminum alloy door and window glass installation technology

[China Aluminum Industry Network] 1. Construction Preparation (1) Materials: glass, glass blocks, and sealing materials. Glass: The glass used for aluminum alloy doors and windows has normal flat glass, and flat glass that is preferably produced by the float process. There are tempered glass, sharp glass, heat reflective glass and so on. Auxiliary materials: fillers, glass blocks, sealing materials. Filling material: It is the backing material used for caulking. It is a kind of polymer foamed object, its shape is generally round, semi-circular, oval and triangular. Specifications are lOmm, 30mm and 50mm three kinds of polyethylene foam. The elongation is 50%, and the tensile strength is between 0.359 and 0.517 MPa. Glass blocks: mainly neoprene blocks, lead strips, and polyethylene nylon. There are two kinds of functions: the glass and aluminum alloy slots and the metal parts at the bottom of the slot are in front of each other to ensure the relative size of the glass and the metal frame; the second is to prevent the glass from colliding with the metal parts due to the expansion and contraction. The role. Sealing materials: According to their different materials can be divided into structural sealant, construction sealant (weatherable adhesive) and hollow glass two sealant. Structural sealant can be divided into two kinds of single-component and two-component. One-component sealant is divided into acid sealant and neutral sealant. According to the method of installing and fixing glass, different sealing materials are divided into two kinds of dry materials and wet materials. When used, dry materials can be used inside and outside, but also inside and outside the full use of wet, or can be mixed; that is, when the outer side of the installation of glass to dry outside the wet material, or the inside of the glass when installed with dry internal use of wet materials. Dry materials are finished products (the market has) divided into several types according to the different types of aluminum alloy slots, and the degree of softness and hardness are also different. According to the different materials of several kinds of sealants, their classification properties and precautions for use are as follows: The structural sealant is generally a silicone sealant. Its main component is silicon dioxide, which is a cement that fixes the glass and makes it reliably connected to the aluminum frame. This glue affects the thermal stress, wind load weather, or earthquake. All have the corresponding resistance. This glue is suitable for structural glass and large-area glass doors and windows. Structural sealant is divided into two kinds of single-component and two-component, single-component sealant with acid-based acid sealant and ethanol-based neutral sealant. For the coated glass, neutral glue must be used, and no acidic glue is allowed. Insulating glass should also use neutral glue. One-component sealant types and properties. The two-component sealant is a kind of sealant which is prepared by mixing the base glue and the curing agent separately in two types of packaging containers and mixing them with a certain proportion before use. The proportion of base rubber and curing agent is proportional to the curing time, and the larger the ratio, the greater the curing time. Different types of glue have their own advantages, but it is more suitable for aluminum alloy window glass installation or single-component sealant at the construction site. (2) Machines are required to have glass suction cups, glue guns, hammers, screwdrivers, electric drills, grinding machines, nailing machines, line hammers, level gauges, and various measuring scales. There is also a stopper for inserting pad clips, a bead roller for inserting a pad, and so on. These machines have some (3) Construction conditions. The door and window frame fan has been installed and has been flexibly debugged. The gap between the frame and the wall has been fixed and has a certain strength. The inspection and acceptance procedures have been completed. The slot of the door and window glass has been cleaned, there is no dust and dirt, and it has glass installation conditions. The drain hole of the glass window slot is unobstructed and clean. The glass has been cut to the required size or has been processed and shipped to the site. It has been placed according to the specified location and stacking form and requirements, and other relevant auxiliary materials have also been shipped to the site. The glass surface is free of moisture, dust, grease, oil, or other harmful substances and is scrubbed clean. Scaffolding or hanging basket facilities are already in place and have been commissioned by security personnel to permit use. Glass installation has been chosen for glass installation weather conditions or environments. 2. Aluminum alloy door and window glass installation method: There are two kinds of outside installation method and inside installation method. (1) The outside installation method is where the operator stands on the scaffold or basket to perform the glass installation of aluminum alloy glazing. Fix the sealing strip on the inner side first. After the glass is positioned, fix the outer side and inject the sealant into the cavity to fix it. This is a mixed use of wet and dry materials. (2) The inner side installation method is the opposite of the outer side installation method. The operator is to install aluminum alloy doors and windows on the high stool on the indoor floor or indoors. First, fix the sealing strip in the outside notch of the window and secure the glass. After positioning, fix it to the inner side and inject the sealant in the cavity of the notch. This is also the practice of mixing wet and dry materials. . The above two methods can also use only a single material, namely a dry material or a wet material. If wet materials are used, one side should be fixed first, and the other side should be injected with glue. Whether using the inside mounting method or the outside mounting method, it is preferable to use wet materials on both sides. For better water-tight and air-tight properties, and better aging, it is better to use silicone sealant. For general simple aluminum alloy doors and windows, single-layer glass is used, and dry materials are used inside and outside the fixed glass. For high-grade aluminum alloy doors and windows, sandwich or hollow glass is generally used. Glass raw materials are often made of processed heat-absorbing glass or stained glass. All methods for fixing glass are all wet or mixed materials.
