Ink cleaning agent and recycling (on)

Environmental protection is an eternal theme that preserves the human living environment. The development and application of environmental protection products can effectively avoid the conflict between the high-tech industrialized society and the ecological environment. As part of modern industrial enterprises, printing companies should also shoulder the responsibility of protecting the environment. On the one hand, in the long run or on the whole, it is the fulfillment of obligations to human society. In addition, in the short-term or in part, it is the development of the enterprise itself. need. At the end of 2001, China’s economy was formally added to the global economic integration after China's accession to the WTO. For domestic printing companies, there are boundless business opportunities and strong challenges. One of the challenges that must be faced is environmental protection. .
First of all, in the long run or on the whole, the significance of various domestic printing companies undertaking environmental protection obligations is self-evident, not only to protect their natural environment, to improve their people’s deteriorating living environment, but also to protect and improve the entire planet’s humanity. The natural environment on which we live depends on the fact that mankind will always have a beautiful “green” earth.
Secondly, in the short-term or in part, regardless of whether or not companies participate in international competition, they must speed up the solution to the pollution problems caused by their own production. On the one hand, with the success of China's accession to the WTO and the bid to host the 2008 Olympic Games, the Chinese government has accelerated the pace of environmental protection and increased environmental protection. New laws and regulations related to environmental protection have been introduced; at the same time, environmental protection agencies have also added Examined and cracked. On the other hand, pollutants such as waste gas, liquid waste and noise generated by enterprises will directly lead to environmental deterioration in the surrounding areas. Deterioration of the surrounding environment will directly or indirectly increase the related costs of the enterprises and will not be conducive to the long-term development of the enterprises. For those domestic printing companies that have joined or are about to join the international competition, environmental protection is an important issue that must be valued in the development of enterprises.
As global economic integration and trade liberalization continue to increase, various tariff and non-tariff barriers are restricted by international free trade treaties and agreements. In this case, developed countries protect their domestic industries and trade protection in the name of environmental protection. In fact, the “green barriers” have been built. The essence of this is that importing countries restrict imports and protect their own trade on the grounds of protecting the ecological environment and human health; the common practice is to establish environmental protection laws and regulations by establishing various environmental protection laws and regulations. Strict environmental and technical standards, the development of cumbersome inspections, approval procedures, etc., impose barriers to the import of products, so environmental standards are a manifestation of the value of environmental resources during a period of economic development. The relevant provisions of the WTO agreement must not prevent any country from taking the necessary measures to protect the health of human beings, living things and protect the environment, which provides a basis for the developed countries to build green barriers. The main manifestations of green barriers are the green tariff system, market access system, green technology standard system, and green environmental sign system. It is a new type of non-tariff barrier. For example: The environmental protection requirements for packaging that are currently allowed in the international market and between countries are:
1Conform to the conditions of international environmental certification.
● The raw material of the product is non-toxic and harmless, and it is a green quality material;
● During the manufacturing process, the production process is pollution-free and clean production is implemented (ie, there must be no pollution upstream or downstream of the production. For example, the pollution of traditional papermaking is serious and plastic products are not easily degraded after being discarded);
● Printing materials in the entire process must be non-toxic and harmless;
● The product quality should be all-round green, and the texture and accessories should be green.
2 Products must have a national guarantee (eg no pests, degradable, recyclable, green signs).
In this way, for our country's printing companies, corporate products and production processes must meet the requirements of international trade before they can join the international competition.
However, even though China's accession to the WTO has been more than a year, the work and efforts made by most of the printing companies in China in the area of ​​environmental protection have been slow and almost zero. Next, we will briefly discuss the environmental issues in the use of ink cleaners by domestic printing companies.
At present, the main body of printing industry in China is offset printing. This printing method cannot be separated from offset printing inks, and thus ink cleaning agents are indispensable. Ink cleaning agents are divided into two major categories: one is steam, kerosene, and the other is a special printing cleaning agent (professional commonly known as "car wash water").
Steam and kerosene are broad-spectrum organic solvents that are suitable for many industries and are relatively inexpensive. That is, the price factor makes most printing companies use car wash water instead of steam and kerosene, but at the same time, they are still using steam and kerosene in large quantities to reduce production costs. So far, in Beijing, where the printing industry is more developed, there is almost no printing factory that uses steam or kerosene as an ink cleaner more or less. Although various printing companies are very aware of the dangers of gasoline:
The first is the security issue. Because the flash point of gasoline (that is, the temperature at which steam encounters an open flame) is only about two dozen degrees, if the ventilation facilities in the printing plant are not good, it is easy to have a dangerous situation; it turns out to be true that Beijing has more than one printing company in the workforce. An explosion occurred when cleaning the printer with gasoline. Even if the air inside the factory is well distributed, no danger will occur in the workshop. However, the steam and kerosene that have been washed out of the ink will be completely poured into the sewers by the workers. Needless to say, the pollution to the soil and water quality, and the gasoline floating on the water at the same time, In the season when the outdoor temperature is relatively high, there is also the danger of explosion.
