How to use glass glue
1. Use: One-component silica gel glass glue can be used immediately. It can be easily punched out of a plastic bottle with a glue gun, and its surface can be trimmed with a scraper or sawdust.
2. Sticking time: The curing process of silicone adhesive develops inward from the surface, and the drying time and curing time of silica gel surface with different characteristics are different, so if the surface is to be repaired, it must be done before the surface of glass adhesive is dried (acid adhesive and neutral transparent adhesive should generally be within 5- 10 minute, and neutral variegated adhesive should generally be within 30 minutes). If a place is pasted with color separation paper, it must be taken away before the skin is formed after gluing.
3. Curing time: The curing time of glass glue increases with the increase of bonding thickness. For example, acid glass glue with a thickness of 12mm may take 3-4 days to cure, but in about 24 hours, the outer layer of 3mm has already cured. When glass, metal or most wood are bonded, the peel strength is 20 lbs/inch after 72 hours at room temperature. If the place where the glass glue is used is partially or completely closed, then the curing time is determined by the tightness of the seal. In an absolutely closed place, it may never be cured. If the temperature rises, the glass glue will soften. The gap between metal-to-metal bonding surfaces should not exceed 25mm. In all kinds of bonding occasions, including closed conditions, before using bonding equipment, it is necessary to comprehensively check the bonding effect. During the curing process of acidic glass glue, there will be an odor due to the volatilization of acetic acid, which will disappear during the curing process and there will be no odor after curing.
4. Bonding: A. Wipe the metal and plastic surfaces thoroughly to remove oil stains. Then, in addition to washing the plastic with acetone, the rubber surface should be polished with sandpaper, and then wiped with acetone. Please observe the precautions when using acetone. B. Apply the glass glue evenly on the surface of the prepared object. If two surfaces are bonded together, you can put one surface first, and then squeeze the other surface with enough force to squeeze out the air, but be careful not to squeeze out the glass glue. C, placing the bonded device at room temperature until the glass glue is cured.
5. Sealing: When sealing with silicone glass glue, follow the above steps, and press the glass glue into the joint surface or gap to make the glass glue fully contact with the surface.
6. Cleaning: glass glue can be wiped off with cloth or paper towel before curing, scraped off with scraper after curing or scrubbed with xylene, acetone and other solvents.
Operating steps of using glass glue
It's beautiful when you hit it along a line, and you can't stop. The force should be even, and it should be hit in place at one time to ensure beauty.
The first point: first of all, you should know how to use a glue gun;
The second point: determine the width of your glue, that is, the width of the gap;
The third point: according to the width of your glue joint, cut the glue nozzle into a slightly smaller caliber than the gap;
The fourth point: do a good job of protecting both sides of the glue gap, and stick 2-3CM tape on the glass, profile and stone on both sides of the gap, which will protect the glass, profile and stone on both sides and is very convenient to correct the glue in the gap;
Fifth, master the speed of gluing and the moving speed of the glue gun, and move the glue gun evenly according to the depth of the gap;
The sixth point: repair the gluing area, find the uneven place scraped by the shovel, and fill the glue where there is no gap when gluing;
Seventh point: After 48 hours, remove the adhesive tapes on both sides of the material and complete the construction.
Matters needing attention in using glass glue
1, the most common problem of glass glue is that it turns black and moldy. Even if waterproof glass glue and mildew-proof glass glue are used, such problems cannot be completely avoided. Therefore, it is not suitable for construction in places with water or long-term immersion.
2. Anyone who knows something about glass glue should know that glass glue is an organic substance, which is easily soluble in organic solvents such as oil, xylene and acetone, so glass glue cannot be applied to substrates containing such substances.
3. Ordinary glass glue can only be cured with the participation of moisture in the air, except special and special glass glue (such as anaerobic glue). Therefore, if the place where you want to build is a closed space and it is extremely dry, ordinary glass glue can't do it.
4. The surface of the substrate bonded with glass glue must be clean and free of other attachments (such as dust). ), otherwise the glass glue will not stick firmly or fall off after curing.
5. Acidic glass glue will release irritating gas during curing, which will stimulate eyes and respiratory tract. So be sure to open the doors and windows after construction, and then move in after the gas is completely cured.
abstract
It is important to learn to use glass glue. Glass glue is not only used for the installation of our family wardrobe, doors and windows, but also for the installation and maintenance of car windows that we often do. If our doors and windows are used for a long time, the glass glue may fall off. At this time, we also need to maintain them with new glass glue. However, when buying glass glue, you must choose a big brand. Glass glue will inevitably smell, but it must not be too heavy. I hope this article is helpful to you!
