Your worry is normal, because if as a project, if the product quality is not good, which leads to problems in the project, it will be in trouble, and it will be terrible if the project is not accepted. Therefore, don't be greedy and cheap, even if you earn less money in the middle, don't risk using products with unstable quality. Now there are not many domestic soft porcelain manufacturers. At present, only the first-line brands such as Meg Soft Porcelain and Fu Mei Soft Porcelain really master MCM soft porcelain technology. Good soft porcelain should have good acid and alkali resistance, freeze-thaw resistance, stable quality, water resistance, air permeability and weather resistance for more than 30 years, and all testing standards should meet the national standard! Hope to adopt, you can ask if you don't understand.
