"Properties for Polyester Bottle Tablets for Drinking Water Tanks" Make Progress

Yizheng Chemical Fibre Co., Ltd. has made positive progress in the project of â€œPolyester Bottle Tablets for Drinking Water Tanksâ€ declared to be developed by Sinopec in 2007. Recently, this project has passed Sinopec's appraisal to form a mature complete set of process technology, achieved industrial production, and the overall technology has reached the domestic advanced level, opening up new application fields for polyester products.
Since 2005, China's bottled polyester production capacity has reached 3.4 million tons, which is equivalent to the global production capacity of 3.3 million tons of polycarbonate for drinking water tanks on the market, which means that there are sufficient raw materials for the production of various kinds of polyester bottles. It also brings significant business opportunities for the production of buckets. Yizheng Chemical Fiber, as a super-sized polyester production enterprise, has achieved fruitful results in the development of carbonated beverage bottles, filling and filling, and PET bottles for oil bottles. With mature experience, the company is targeting optical bottles for drinking water barrels. The development of special materials for tablets will be supported by Sinopec and users.
To develop this project from a more hygienic and safer point of view, Yizheng Chemical Fiber worked on the formulation of PET bottles for drinking water barrels, and adjusted the crystallization capabilities of various commonly used bottle fins on the market to identify drinking water tank PET bottles. The production formula of the special materials for tablets and the use of self-produced basic slices for viscosity-enhancement studies the quality indicators and production processes of bottled water PET bottles. After industrial trial production, various indicators of the project were gradually improved, and mass production on industrial production facilities was realized. At present, Yizheng Chemical Fiber has produced 5 gallon bucket special materials BG803 PET bottle tablets according to market demand, which is an excellent brand of drinking water barrel PET bottle tablets recognized in the market. The product has been sold to Zhejiang, Jiangsu, Fujian, Shandong, Anhui, Tianjin and other provinces and cities. It is used to produce 5 gallon buckets of billet, and is blown into various types of drinking water barrels. At the same time, the tube blanks produced are also exported.
The main factors affecting the hygiene of polyesters are acetaldehyde content and heavy metal content. At present, the content of acetaldehyde in BG803 PET bottle tablets developed by Yizheng Chemical Fiber is less than 1ppm, and the content of hydrazine is the lowest compared with similar products, and it meets all current regulatory requirements. After the end of the service life of the polyester bucket produced with Yizheng Chemical Fiber raw materials, it can be recycled as a general waste PET bottle, and the recycling rate is higher than other materials. Even if it is treated as waste, it will be environmentally friendly due to its low calorific value of combustible calories, no harmful gases, and no environmental pollution.
