comparison test of 25 home decoration paint samples of Harbin Consumer Association

June 21, 2007

[China paint information] a few days ago, Harbin Consumer Association in Heilongjiang Province conducted a comparative test of home decoration paint products. The results showed that the quality of home decoration paint on the market was reassuring, and only one sample was unqualified in terms of washability

according to the introduction, the 25 samples of home decoration paint for this comparative test were purchased in the home decoration market by the staff of Harbin consumers' Association as ordinary consumers, and Harbin Institute of product quality supervision was entrusted to conduct a comparative test on three indicators of home decoration paint, namely, the washability, contrast rate and formaldehyde content, according to the national standards GB/t9756-2001 and gb18582-2001

the comparison test results show that the "Aobao" high-grade environmental protection wall paint produced by Tianjin Kewen Chemical Co., Ltd., which is nominal to achieve a win-win situation, fails to meet the minimum standard specified in the national standard, and the washing and brushing times are 147, which is an unqualified commodity. The washability indexes of other home decoration coating products are up to standard, and the qualified rate is 9. Coal mines need a certain reaction time of 6%. Among them, there are 22 samples with a washing resistance of more than 1000 times (meeting the standard of excellent products), and 8 samples with more than 20000 times

the contrast rate of the 25 home decoration coating commodities sampled met the first-class requirements specified in the national standard. Among them, 21 samples reached the standard of excellent commodities stipulated in the national standard. In addition, the formaldehyde content of 25 home decoration coating commodities did not exceed the index quantity specified in the national standard. Among them, there are 23 samples whose formaldehyde content index is 3 digits after the decimal point, which reflects that the production enterprises have relatively strict management on this index

according to the index data of the pilot project, Harbin consumers' Association evaluated the star rating of the samples taken this time. For painting, we need to pay attention to some individual places: if the three indicators of washability, contrast ratio and formaldehyde content of the material meet the national minimum standards, an asterisk will be given; If the washability meets the national standard for superior products (more than 1000 washability times), an asterisk will be given; If the contrast rate reaches the national standard, the superior products (above 0.95) will be given an asterisk; If the formaldehyde content is equal to or lower than the national standard (0.1g/kg), an asterisk will be given; If the washability exceeds 20000 times, an asterisk will be added. If it fails to meet the minimum qualification standard set by the state, it will not be evaluated. According to this, the highest star level is 5 stars. Among the 25 home decoration coating commodities evaluated, 7 samples obtained 5 asterisks, accounting for 28% of the inspected commodities; There are 14 samples with 4 asterisks, accounting for 56% of the inspected goods; Three samples with three asterisks, accounting for 12% of the inspected commodities, obtained and planned to reduce the annual output of hydrofluorocarbon materials with high global warming potential by 50% by 2020; One sample with two asterisks was obtained, accounting for 0.04%; One sample that did not meet the requirements of the national standard for qualified commodities and was not evaluated accounted for 0.04%
