On June 3, Li Zhaohua, senior expert of Qilu Petrochemical chemical process, was carefully combing the polyvinyl chloride resin test report data sent by SGS (Swiss general Notarial firm). The results show that the four grades of PVC resin products of chlor-alkali plant successfully passed SGS certification, fully meeting the European Union and international standards, which provides a strong basis for the company's PVC resin and its products to export to the international market.

SGS is a Swiss general notarial firm, founded in 1878, is the world's largest third party inspection, identification, testing and certification body, testing standards are high, its results are recognized worldwide." Our products through SGS certification, meet the international quality standards, get the global market pass." Li Zhaohua said proudly.

Since the beginning of this year, in order to broaden the sales channels of PVC resin products and push Qilu petrochemical products to the world, chlor-alkali factory on the one hand actively according to the test requirements, put forward certification applications, and take the initiative to provide test samples; On the other hand, self-pressure, standard advanced enterprises, strict raw material quality, production process and factory control, and continue to improve the rate of excellent products.

In view of the actual situation of fluctuations in product quality caused by unstable reaction of direct chlorination unit, they organize technical personnel to closely track the relationship between catalyst ratio and reaction, and fine-tune at any time. Through continuous research, the purity of direct chlorination unit products has gradually increased to 99.6%, reaching the best level in the past 10 years.

At the same time, the chlor-alkali plant also repeatedly connected with the research institute, adjusted the formula of the production of polyvinyl chloride, determined the specific content and objectives of the quality improvement, regularly organized the research meeting, found the causes of quality problems, and implemented the solution measures. Since the beginning of this year, the factory's polyvinyl chloride resin products excellent product rate reached 97.81%, an increase of 2.76%.
