Color difference, The reasons: 1, Putty powder itself is semi-finished products, raw materials instability is one of the main reasons leading to color difference, due to mineral powder quality is different because of different mining region, if not pay attention to deployment, there will be the color difference for different batches. 2, Because the suppliers use the "make up the number" approach to make the low-grade raw materials mixed delivery, because that the purchase quantity is large and it can not be spot checked in one by one, resulting in individual "a fish slip through the net" mixed in the production which led to individual color difference. 3, Due to production pesonnel's mistake in mixing different gradesof raw materials together causes the color difference,or different grades of raw materials mixed in the production scraped on the same wall cause the color difference. ....

Ceramic tile construction, common problems, solutions Ⅰ, The back of tile appears the hollow phenomenon 1 Use the larger size gear scraper 2 Increase the inclination of the profile scraper and the base surface Ⅱ, The rack gule layer is not uniform 1 The scraping thickness of the mortar is not enough. 2, the hole has been dry glue, should be cleaned tooth scraper. 3, Slow down the scraping speed. 4, Glue adhesive mixing is not uniform, the glue should be fully stirred. Ⅲ , The bond is not strong 1, The base surface is loose (dust, etc.), should be cleaned. 2, There is water, should be dry to no clear water. 3, There are oil contamination, stain, should be cleaned. ....

1.)抗裂防护层的抗裂问题是主要矛盾，必须采用专用的抗裂砂浆并辅以合理的增强网，在砂浆中加入适量的聚合物和纤维，这对控制裂缝的产生是有效的。 2.)由抹面砂浆与增强网构成的抗裂防护层对整个系统的抗裂性能起着比较关键的作用。抹面砂浆的柔韧极限、拉伸变形应大于最不利情况下的自身变形（干缩变形、化学变形、湿度变形、温度变形）及基层变形之和，从....

A road asphalt pavement disease is the result of many factors, there are many kinds, but mainly for cracks, rutting, subsidence, pits, oil and grease, the road goes. 1. cracks: transverse cracks. Transverse cracks are regular cracks perpendicular to the direction of the line, longitudinal cracks. Longitudinal cracks are parallel or basically parallel cracks in the direction of the line. Cross cracks. Two or more than two cross cracks, known as cross cracks. 2. rutting: the vehicle leaves behind the road....

1. Too much foam during the mixing: It is a normal phenomenon, the main reasons is too shallow, too little water to form, it will appear overnight naturally.....

Different manufacturers of cement self-leveling, there will be different problems tend , products from A manufacturer may has the problem of "white spot" , products from B manufacturer may have the problem of "cloth pattern furrows". This requires familiarity with the properties of different brand cement in the construction and development of the targeted construction process, so as to ensure that the cement self-leveling ground perfect. Cheng Cheng Hao Xin brand self-leveling cement adopt the advanced technology from Germany with quality assurance and good price, as long as you are in the correct construction process, there will be able to make your satisfaction with the ground effect. ....
