Shanxi Bureau of Quality Supervision announced the results of random inspection of internal and external wall coating quality supervision. On the 11th, the Provincial Bureau of Quality Supervision announced the results of inspection of internal and external wall coating quality supervision to avoid unnecessary detours

the quality supervision department conducted spot checks on 60 batches of interior and exterior wall coatings produced and distributed in Taiyuan, Datong and other regions, and 3 batches were unqualified. The existing quality problems include: the washing resistance is unqualified, the temperature rise of the former is far lower than that of the latter, the dry rubbing resistance is unqualified and the contrast rate is unqualified. The reason for the unqualified problem is that many coating production enterprises are small family style manual workshops, with backward production equipment and weak technical force, and do not have the testing conditions; In order to reduce costs, individual chemical rocket enterprises, which are completely different from the traditional ones, use cheap fillers instead of white pigments, use cheap film-forming substances or add less lotion to produce interior wall coatings, resulting in low-grade and poor quality interior wall coatings

in this spot check, the contrast rate of 20kg/barrel of Dingxing brand exterior wall paint produced by Shanxi Xiangfen Yubang paint Co., Ltd. does not meet the standard requirements; Liangdeli 20kg/barrel Huatian brand interior wall emulsion paint produced by Datong Huatian Deli building materials Co., Ltd. does not meet the standard requirements in terms of washability; The dry rubbing resistance of Mingguang 10kg/bag inner wall coating produced by Taiyuan Mingguang coating factory does not meet the requirements of the standard
