In order to objectively and comprehensively reflect the quality status of PVC products in China, analyze the existing problems, guide and promote the steady improvement of the quality of PVC resin products, and promote the strategic work of famous brand products in the industry, China and the Petrochemical Industry Association recently organized the quality supervision and Inspection Center for chlor alkali and chlorine products in the chemical industry to carry out the industrial unified inspection and spot check on the domestic suspension universal PVC resin

according to the introduction, 68 samples produced by 62 enterprises were randomly selected. The production enterprises were distributed in 19 provinces, cities and autonomous regions such as Jilin, Heilongjiang, Hebei, Henan, Shanxi, Shandong, Inner Mongolia, Ningxia, Shaanxi, Jiangsu, Zhejiang, Jiangxi, Hunan, Hubei, Fujian, Sichuan, Beijing, Shanghai and Tianjin, accounting for 81% of the total number of production enterprises and 87.5% of the total output of the country. Among the samples sampled, except that the samples sampled by one enterprise were treated as unqualified because they were not delivered, the overall sampling pass rate was 98.5%, and the enterprise pass rate was 98.4%

according to the analysis of the spot check results, the overall quality awareness of the industry is strong, the product quality is stable, and meets the requirements of the current standards, which objectively reflects the current national quality level of the product and, for example, the status of the reader disk universal testing machine industry. Among them, large state-owned enterprises such as Shanghai Chlor Alkali Chemical Co., Ltd., Tianjin lejin Dagu Chemical Co., Ltd., Tianjin Botian Chemical Co., Ltd., Tianjin Dagu Chemical Co., Ltd., Beijing No. 2 Chemical Co., Ltd., Sichuan Jinlu resin Co., Ltd. and Qingdao Haijing Chemical Group Co., Ltd. have high quality awareness, institutionalized and standardized management, and sound quality inspection institutions, Guided by users and the market, the company has gained the trust of users and won the market by implementing a reward mechanism to encourage high-quality products, increasing internal control indicators, increasing type inspection items, tightening the inspection of final products, and strengthening pre-sales, in-sales and after-sales services, The products of these enterprises have been awarded big picture 1 by the local relevant departments: reasons for invalid materials or phenomena. There is no need to worry about the title of local high-quality products or inspection free products. Some enterprises have made great efforts in projects that can show the internal quality and operation technical level of PVC resin, such as "fish eye" number, heat aging whiteness, plasticizer absorption, number of impurity particles, etc., and have determined internal control indicators higher than the national standard of high-quality products, so that their products can be comparable with the advanced level of foreign countries

however, some problems were found during the random inspection, which should be paid great attention to: first, some small and medium-sized enterprises, due to capital and other reasons, did not make great efforts to transform technology and equipment, and there is still a large gap in product quality compared with large enterprises. Most small enterprises have a serious shortage of the ability to produce high-grade resin. They only produce qualified grade resin to maintain production. From the trend, if they do not speed up the pace of technological transformation, they will be gradually eliminated by the market; Second, there are still a small number of enterprises with poor quality awareness, imperfect quality inspection institutions, lack of necessary inspection equipment, lack of training for quality inspectors, and failure to inspect products in accordance with the mandatory national standard gb5761-1993. Enterprises do not pay attention to product quality; Third, the current national standards have fallen behind and can not meet the needs of product development
