Stone has long been a widely used decorative material in the modern construction industry, but stone materials are more or less used in the paving process, such as caulking agents, adhesives, etc., which are mainly used To seal the stone during the paving process, but if the materials are improperly used in the process of paving the stone, or the proportion of the materials used in the process is not in place, it will affect the performance of the stone later, paving the stone. How to use the excipients in the process? How do the different excipients ratio?
1, caulking agent:
At present, there are mainly three types of caulking agents that can be used for stone paving, which are suitable for different gaps: 1) no sand type caulking agent - suitable for gaps below 3 mm; 2) anti-mold caulking agent (ie fine sand type) - suitable for 3MM-5MM gap; 3) Stone caulking agent (ie coarse sand type) - suitable for 5MM-12MM gap.
2. Binder:
1) In addition to the rubber compound, the binder also includes auxiliary components such as a solvent, a curing agent, a toughening agent, a preservative, a coloring agent, and an antifoaming agent. In addition to the most commonly used animal glues, the binders include synthetic resins, rubber and paints.
2) The foundation surface of the construction must be smooth and dry, the surface is clean, free of dust and oil, and there is no phenomenon of peeling and powder falling.
3) During construction, a 6 mm toothed file is used on the wall surface, and a 10 mm toothed file is used on the floor. The binder is textured and spliced ​​with a file to make the tile and the adhesive fully adhered to maintain The flatness and strength of the bond.
4), adhesive, tile and base surface do not need to be soaked and wetted.
Whether it is a caulking agent or a binder, if the paving process of the stone is more perfect, then the proportion of the proportion should be paid attention to during the use. At present, the main matching methods are mainly as follows:
1. Scientific ratio: Add the clean water to the clean container according to the water-cement ratio of 1:4 (using the machine to stir the ratio of water to lime of 1:5), and slowly add the sealant (binder).
2, fully stirred: fully stirred until no agglomerate paste, stand for 3-5 minutes, stir again before use, the heart after stirring must be used within two hours, such as solidification, can not add water, Must be discarded.
