Hebei Zhiyoujie: the source, process and end are opened up, and the VOCs governance effect is significant

In order to maintain the sustainable development of soft packaging enterprises, it is necessary to meet the standard of environmental protection. Since the promulgation of the air pollution control laws and regulations, many soft package enterprises have started to take various measures to control VOCs. After years of exploration and discussion, a large number of outstanding enterprises have emerged in environmental protection. Hebei Zhiyoujie New Materials Technology Co., Ltd. is one of the leaders. In the comprehensive control of VOCs, Zhiyoujie has chosen source substitution, process control Combination of end treatment. For terminal treatment, Zhiyoujie finally selected Edvance, which has nearly 1000 cases in the world, to provide it with environmental protection and energy saving equipment - organic waste gas treatment and thermal storage incineration equipment (RTO). The RTO treatment efficiency is more than 95%. The waste heat generated by RTO provides heat energy for production lines and workshops, realizing an effective combination of social responsibility, economic benefits and ecological benefits in the overall treatment process. I believe that their valuable experience will certainly bring valuable reference to the soft package enterprises that are still looking for appropriate governance solutions.

Progress in application of precision coating technology

Application progress of precision coating technology precision coating is an important processing technology to change and improve the surface characteristics of materials. with the continuous development of science and technology, precision coating has become an indispensable technical means for the research and development of many important functional materials. In particular, precision coating technology can meet the special requirements of some coatings, thereby increasing the added value of materials and expanding their application scope.

Characteristics and application of precision coater

With the development of modern electronic industry, precision coating has been gradually developed. After the fine painting technology in the United States, the development of Japan and Europe has been quite mature, while the technology in Taiwan is relatively insufficient. The obstacle to the localization of imported air flotation furnace lies in the high price. The material basis of precision coating process is precision coating equipment. The main characteristics of precision coating are: slot extrusion, precision leveling rod, air drying, coating damping magnetoresistive head, and gas-liquid buffer support.

How do cigarette package printing enterprises deal with VOCs? Don't deal with it blindly!

Speaking of tobacco packaging, it broadly refers to the packaging materials used in the production of cigarettes, mainly including cigarette paper, filter rod forming paper, splicing paper, lining paper, frame paper, box packaging paper, strip packaging paper, label sealing paper, cigarette cartons, etc; In a narrow sense, it only refers to box wrapping paper and strip wrapping paper (commonly known as cigarette packs, decoration or trademark paper). It can be seen that the production of most tobacco packaging materials can not be separated from printing, which covers gravure printing, offset printing, screen printing, flexographic printing and other processes. Facing the decisive year of pollution prevention and control in 2020, and the general requirements of environmental protection governance of the country that "adhere to the same direction, do not reduce efforts, highlight the precise, scientific and legal pollution control, and promote the sustainable improvement of ecological environment quality", cigarette packaging and printing enterprises have become the key work to be solved urgently. The author is in Wuxi ATI Group Technology Co., Ltd. (ATI), a Sino US cooperation high-tech enterprise specializing in the design and manufacture of waste gas treatment equipment, which has completed more than 80 VOCs waste gas treatment projects with a number of domestic cigarette package printing enterprises, and has achieved good ecological, environmental, economic and social benefits. Here we share our VOCs waste gas treatment experience with you.

Precision coating technology

Understand the precision coating process. The traditional precision coating methods, such as blade coating or roller precision coating, are simple and convenient to operate, but can only produce low value products at a unit price of less than 10 yuan per square meter. Moreover, this coating method belongs to an open operation mode, and solvent evaporation affects the health of operators. Environmental protection awareness is becoming increasingly important today, so it is necessary to make appropriate adjustments.
