The difference between the true porcelain glue and beautiful seam an agent, Which is better? ）

Traditional cement-based caulking agent are easy to stain, off powder, shortcomings and so on is not easy to clean, easy to mildew, color is relatively single, more and more can't satisfy people's needs, more colorful and less contamination of true porcelain glue and seam an agent arises at the historic moment. True porcelain glue and seam an agent is due to the market demand of the product, there are no national or industry standards, is the industry the established name, drill porcelain glue, really like the king of porcelain are true porcelain glue used. Below we simply analyse the difference between the true porcelain glue and beautiful seam an agent.

chemical composition and form the difference between the

true porcelain glue both single tube and double tube is a two-component packaging, one of the components is made up of waterborne epoxy resin, fillers, additives, which is a mixture of another component is made from a mix of curing agent and additives, when use two components mix, water-based epoxy resin and curing agent with crosslinking reaction, form a three-dimensional network structure. The seam an agent is from low glass transition temperature of pure acrylic emulsion or styrene acrylic emulsion and fillers, thickening agent, defoaming agent, fungicide mixture preparation, such as main cementing material is pure c or styrene acrylic emulsion, the seam an agent are one-component packaging.

on the physical properties of the difference between the

it is because of true porcelain glue and seam an agent on the chemical composition of different, large differences in the macroscopic physical properties. The seam an agent is through a mixture of evaporation, water emulsion film, forming a continuous whole. Dry film forming process is mainly physical process, evaporation in the process of dry wool stoma has a large influence on the late performance. And true porcelain glue work process is the cross-linking reaction of waterborne epoxy resin and curing agent, is a chemical process. Show true porcelain more higher adhesive strength, hardness, surface density and better stain resistance, scrub easier. Beautiful seam an agent in the drying process as the moisture evaporates along with volume decreases, and this is the seam an agent prone to collapse and true porcelain gum won't appear the cause of the collapse, damp environment or meet water water is transferred through the wool stoma inward, film appear the phenomenon of swelling soft, beautiful seam an agent's strength is much lower than true porcelain gum, late falls off phenomenon is also more common.

impact on ceramic tile shop sticks system

caulking materials is important for ceramic tile shop is stuck, on the one hand, the flexible joint sealant is ceramic tile heat bilges cold shrink, such as drying shrinkage deformation when the buffer space, can greatly reduce the ceramic tile interface shear stress, reduce the late empty drum falls off phenomenon. Joint sealant, on the other hand, can rise to prevent moisture to the ceramic tile on the back of the penetration, ceramic tile adhesive strength after water drop phenomenon. Wet bilge drying shrinkage and bonding agent can also affect ceramic tile adhesive strength, so require a good waterproof joint sealant. From the two aspects, the hardness of true porcelain glue was obviously higher than that of the seam an agent, the effect of interfacial shear force on than the seam an agent. Beauty of seam an agent, on the other hand, water proofing property, good water resistance is clearly true porcelain glue, in the later can't have very good protection effect of ceramic tile adhesive.

in aggregate, the seam an agent is generally water-based acrylic emulsion as main preparation of cementation material and film forming process is mainly physical effect, relatively flexible is better, hardness is low, the late after flooding bond strength is relatively low, easy to appear fall off phenomenon. And gum of true porcelain is waterborne epoxy resin system, cementation process is with the curing agent of crosslinking reaction, is a chemical process, higher strength and hardness is higher and more excellent waterproof, stain resistance and scrub resistance, but the true porcelain rubber hardness too high will cause the phenomenon of empty drum ceramic tile.
