日本研制高粘性瓷砖,其目的在于改善瓷砖、墙砖与砂浆的粘结性。用含钙的无机材料如波特兰水泥作面层烧结,形成与水泥水化结合的钙化合物结晶层。其耐候性好,尤其是粘结强度佳,克服了现有瓷砖水湿润性差,不易与砂浆粘结,易脱落的缺陷。试验表明,用100份水泥、200份水和0.5份甲基纤维素制备混合料,涂在素坯上,于1200℃下烧结,制成的 Japan’s development of high-viscosity tiles is aimed at improving the adhesion of tiles, wall tiles and mortar. The calcium-containing inorganic material such as Portland cement is used as the surface layer to form a calcium compound crystal layer combined with cement hydration. The weather resistance is good, especially the bonding strength is good, which overcomes the defects that the existing tile water has poor wettability, is not easy to bond with mortar, and is easy to fall off. The test showed that the mixture was prepared with 100 parts of cement, 200 parts of water and 0.5 parts of methyl cellulose, coated on the china and sintered at 1200°C.
