Tiles is a widely used building material, I believe that many of my friends talk about the tile pavement will be considered cement. This is true, but with the development of technology, tile paving methods are also very diverse, and paving Does not necessarily require the use of cement, you can also use the tile adhesive. So what is the tile adhesive? Let Xiaobian introduce below. What is tile adhesive Tile adhesive, also known as ceramic tile adhesive or binder, glue clay and other names, is a new type of modern decoration materials, instead of the traditional cement yellow sand, glue is cementitious cementitious force several times effectively paste large Tile, to avoid the risk of bricks. Good flexibility to prevent the production hollowing. Mainly used for paste ceramic tile, tile, floor tiles and other decorative materials, widely used in interior and exterior walls, floors, bathrooms, kitchen and other building finishes Decorative place.Its main features are high bonding strength, water resistance, freeze-thaw resistance, anti-aging performance and easy construction, is a very ideal bonding material. Tile adhesive advantages Relative to cement, tile adhesive has many advantages, such as the use of tile glue can save more space than the use of cement, ceramic tile adhesive as long as a thin layer of it, and the cement is relatively thick; strong adhesive tile, if the construction When the process is up to standard, the tile sticks very strong; also can reduce the waste, the poisonous additive, meets the environment request and so on. Tiles glue tips Construction of the wall to be wet (dry in the wet), and maintain a certain degree of roughness, rugged or extremely rough parts of the application of cement mortar and other materials leveling; grass-roots must be removed ash, oil, wax, so as not to affect the degree of adhesion; After the paste tiles can be moved within 5 to 15 minutes to correct the water-cement ratio of about 1: 4, after mixing the binder should be used within 5 to 6 hours (temperature of about 20 degrees); after mixing Of the adhesive smear on the back of the paste brick, and then press hard, until the level until the actual consumption due to different materials and different, generally at least about 4.5 ~ 6 kg per square meter, paste the thickness of about 2 ~ 3mm. Use common sense: 1, acetic acid type: Vulcanization speed, transparency, but in the curing process to release acetic acid; irritating odor, but also on the metal, coated glass and some inorganic materials corrosion. 2, dealcoholization type TC: Curing shrinkage is small, water stripping small, no corrosion on most substrates; Fluorocarbon profiles, steel and white marble poor adhesion; Construction at high temperatures, due to the reaction rate is too fast, resulting in the formation of alcohol Small molecules can not be volatile in time, and the formation of bubbles affect the construction quality.Demo-off type TW: good adhesion can be constructed at the appropriate high temperature, does not produce bubbles; copper and mirror industry rot, and shrinkage than alcohol type large . Use restrictions: Non-structural adhesive banned for structural assembly; should not be used to ooze grease, plasticizers or other solvents, building materials surface; not for frosting or wet surface, long-term buried in the ground or long-term flooding occasions; should not be used for paint The surface may be due to cracks or peeling off the film caused by sealing failure; should not be used for direct contact with food or subject to mechanical wear and tear; should not be used for building materials surface temperature below 4 ℃ or higher than 40 ℃ construction. 3, deacidification type: Acid gel should not be used in cement, stone, because acid glue curing produce acetic acid, with cement, stone and other alkaline materials surface reaction to form a chalky substance, which led to fall off; larger substrate expansion coefficient, There is displacement or vibration, plastic construction hit too thin, are likely to cause the surface of the neutral glue after curing wrinkling phenomenon; such as neutral glue and acid gel may cause the yellowing of neutral glue; (1) high temperature Shi Plastic, high temperature curing; curing speed is too fast, the rate of release of methanol is greater than methanol from the colloid in the rate of excretion of methanol after the gasification bubbles; (2) sizing too thin, less than 6 mm (3) foam rod (bar) caused by the destruction of foam (open-cell foam bar); with moisture; foam material incompatible, chemical reaction; (4) sizing irregular, Can lead to the phenomenon of foaming after sizing. Be careful not to over-squeeze during construction trimming, otherwise it will easily cause deformation of cushion foam rod, after which the foam rod will gradually recover, causing the sealant to bulge as a whole. During construction, try to extend the correction time within the construction allowance and adjust Operation, the use of a scraper from the bottom of the seam upward trimming, to avoid uneven surface after curing the adhesive strip and a small amount of sag; due to the different types of profiles on the market, it is recommended that customers use each batch of plastic products prior to their own simple Of the adhesion test, after the approval of product quality can be widely used, which is to ensure the quality of the project but also to protect their own interests. After reading the introduction of Xiaobian, we now know what is the tile glue it. Xiaobian also give you a detailed introduction to the use of tile glue. If you intend to use tile adhesive paving tiles, then Xiaobian introduction Do not miss it. |
