Caulking agent application of three aspects mainly in?

filled seam an agent in the project of the ceramic tile paste function mainly has three aspects: one is the adornment effect, to match the brick of pottery and porcelain, in appearance as a whole or contrast adornment effect; Secondly, filling effect, will be in the process of brick of pottery and porcelain paste gap filled fully, prevent water seep into the external paste good ceramic tile on the back; A third is the buffer at the grass-roots level, ceramic tile adhesive, ceramic tile, caulking agent in hot cold, such as dry-wet circulation caused by deformation under the action. So when choosing gap filling agent, want to consider: wide seam

different slit width need different caulking agents, wide brick seam strict restriction on the shrinkage of gap filling agent, to avoid cracking. Narrow seam has higher request on the workability of caulking agent. Generally applicable to sew more than 4 mm wide gap filling agent will make packing with sand, this approach is in order to effectively control the shrinkage of caulking agent, to improve the wear resistance and strength; And is suitable for the seam width under 4 mm gap filling agent, since there is no sand do packing, feel is more exquisite. For the luster of the narrow seam glazed tile paste project, recommended not sand fine seam caulking agent, so as to avoid scratches ceramic tile glaze.

use the occasion of

caulking agent also depends on the choice of brick of pottery and porcelain system using occasions, such as: food utensils clean area, swimming pool, health demanding place such as sterile operating room, you should use chemical resistance and little water absorbing reactive caulking agent; Have some bearing requirements of floor tile paste project, you should use high wear resistant caulking agent; Such as kitchen, toilet often damp areas, while guarantee the water proofing property, has good should also be considered in addition to the bad effect of caulking agent.

introduction to choose ceramic tile ceramic tile seam filling agent manufacturer jointing agent must first can't FanJian

in a huge number of user units, inquire unit, the problems about purchasing ceramic tile jointing agent, the most mentioned is ceramic tile of jointing agent FanJian FanJian problem, we must attach importance to the problem. Ceramic tile after jointing agent FanJian serious, can cause the risk of unpredictable, to the building itself will directly affect the safety of the structure, usability problems, so can't ignore the ceramic tile of jointing agent problem.

jointing agent alkali in ceramic tile, dissolved in cement mixing water and cement hardening after penetrating fluid, with the hydration and moisture evaporation, developed a saturated solution of alkali, and with the cement stone wool stoma moisture migration to the cement surface ( The surface hardening jointing agent body) , calcium hydroxide, sodium carbonate and sodium sulfate, calcium carbonate precipitation and white crystals, especially calcium hydroxide in the surface and calcium carbonate and the reaction of carbon dioxide in the atmosphere and water effect paint color, this is FanJian also called 'white frost'. FanJian sometimes affected by climate conditions, low temperature, humidity and no wind condition is likely to be fuelling FanJian phenomenon.

construction in the summer, the temperature is higher, generally speaking, FanJian serious jointing agent, or mean inferior jointing agent products, FanJian speed is very fast, in about five hours of time can see ceramic tile adhesive, the jointing agent the position of the contact with the ceramic tile, particularly evident edge position, appear different degree of white material, the material is jointing agent in alkaline substances.
