Zijiang attaches importance to environmental protection printing, and realizes a win-win situation of economic and social benefits
Shanghai Zijiang Color Printing Packaging Co., Ltd. (hereinafter referred to as "Zijiang Color Printing") is one of the leading enterprises in the field of flexible packaging. As a high-tech enterprise in Shanghai, it is currently a large-scale flexible packaging enterprise with a high degree of automation and high technological content in China. Research, development, production and sales of a variety of flexible packaging materials technologies and products, specializing in providing flexible packaging solutions for the food, pharmaceutical, daily chemical, pesticide and other industries.
In May 2001, Zijiang Color Printing invested in a new modern factory. The entire plant has central air conditioning, fire protection, environmental protection, storage and other systems, which meet international environmental protection, health, and safety requirements. ，环保印刷理念深深融入公司的“血液”，提供富有社会责任的产品和服务已成为公司文化的核心部分之一。 Since moving into the new plant, emission control and environmentally friendly printing have become the consensus of the upper and lower levels of the company. The concept of environmentally friendly printing has been deeply integrated into the company's "blood". Providing socially responsible products and services has become one of the core parts of the company's culture.
1. Introduce advanced environmental protection technology and escort
设备、多层共挤出吹膜设备; Zijiang Color Printing has introduced solvent-free composite equipment and multi-layer co-extrusion film blowing equipment as early as 2000;
; The first in the industry to achieve benzene-free and ketone-free printing in 2006;
投入使用，实现了70%以上复合溶剂的回收再利用; In 2008, the compound solvent recovery device was put into use, and more than 70% of the compound solvent was recovered and reused;
，采用在线检测吸附等先进技术，使得复合溶剂的回收率提高到90%以上 ，VOCs排放达到标准，同时消除了因蒸汽脱附而产生的废水; In 2012, the original complex solvent recovery device was completely updated. From the original steam desorption to nitrogen desorption , advanced technologies such as on- line detection and adsorption were used to increase the recovery rate of composite solvents to more than 90% , and VOCs emissions reached the standard. At the same time, the waste water due to steam desorption is eliminated;
开始实行 印刷溶剂回收，取代原有的催化燃烧装置 …… In 2014, printing solvent recovery was implemented to replace the original catalytic combustion device ...
。 Judging from the experience of Zijiang Color Printing, the initial cost of new technologies and processes will indeed increase manufacturing costs in a short period of time. However, once the new technologies and processes are mature and mastered, the manufacturing costs will be higher than the original technology. Down .
2. Attach importance to end treatment and turn waste into treasure
的效果，为企业创造效益和财富。 In fact, wastes are misplaced resources. If they can be effectively recovered and reused, waste can be turned into treasure, achieving the effect of "low consumption, high utilization, and low emissions" , creating benefits and wealth for enterprises. .
可将生产过程中产生的有机废气通过吸附、还原、精馏提纯、回收并循环使用，不但解决了有机废气排放污染环境的问题，同时还能变废为宝， 对回收溶剂进行循环使用 ，为企业节省了大量的溶剂采购资金，真正实现了节能减排、保护环境和成本节约。 The adsorption-rectification recovery method adopted by the company can use the organic waste gas produced in the production process through adsorption, reduction, distillation, purification, recovery and recycling. Recycling the recovered solvent has saved a large amount of solvent procurement funds for the enterprise, and truly achieved energy conservation, emission reduction, environmental protection and cost savings.
每年可回收1500吨左右的醋酸乙酯溶剂，即使每回收1吨溶剂的运行费用按3000元左右计算，每年也可增加收益500万元左右。 For example, the company's current dry and exhaust gas recovery unit can recover about 1,500 tons of ethyl acetate solvent each year. Even if the operating cost of each ton of solvent recovered is calculated at about 3,000 yuan, the annual revenue can be increased by about 5 million yuan . ，在运行过程中几乎没有废水产生。 And because the device uses high-temperature nitrogen desorption , almost no waste water is generated during operation.
3Combined use in other ways
，通过计算能够有效利用多种剩余油墨，将所需油墨只作最低所需量的配置，以减少剩余油墨。 In addition, Zijiang Color Printing also uses an ink computer color matching system . By calculating, it can effectively use a variety of remaining inks, and only configure the required inks to the minimum required amount to reduce the remaining inks.
，将所有盛放溶剂的桶罐全部加盖，并由生产部门会同人事部门进行检查，督促执行;并对凹印机敞开的墨槽进行封闭改造，减少油墨溶剂的挥发。 Zijiang Color Printing also strengthened the fugitive emission control of VOCs in the workshop, covering all barrels and containers containing solvents, and the production department and the personnel department inspected and supervised the implementation; Closed transformation to reduce volatilization of ink solvents.
"Being pure and innocent, working hard", Zijiang Color Printing will continue to explore the industry by adhering to this motto. 科印网） The future can be expected, let us jointly wish and look forward to! (Source: Keyin.com)
