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. Under such circumstances, developed countries often establish strict regulations by enacting various environmental laws and regulations. The 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 include the green tariff system, market access system, green technical standard system, and green environmental sign system. It is a brand-new non-tariff barrier.
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, although it has been “joining the WTO†for more than a year, the work and efforts made by most printing companies in China in terms of environmental protection are still progressing slowly. In printing companies, manuscripts, films, printing plates, inks, fountain solutions, and printer washing liquids constitute an integral part of the printing process and are an important factor in printing. Some of them constitute a part of the printed products, and some of them become solid, gaseous, liquid waste after they are used in the printing shop. The following will briefly discuss the environmental issues in the use of ink cleaning agents for 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 cleaning agent for printing (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 relatively developed, hardly any printing factory is using steam or kerosene as an ink cleaner more or less. Although the printing companies are very aware of the dangers of gasoline, the first is safety. problem. 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. The second is pollution. As an organic solvent, steam and kerosene are inherently toxic.
In the printing shop, when the workers clean the ink roller, blanket or machine, because of the large volatility of gasoline, even if the ventilation in the workshop is good, the workers will inhale a certain amount of oil and gas more or less; at the same time, the workers During the cleaning operation, the hands or other parts of the body will inevitably come into contact with steam and kerosene; the inhaled gasoline oil and gas and the exposed steam and kerosene will cause some damage to the human body, and the short-term contact problem will not be too great, but if Long-term exposure will cause varying degrees of damage to workers' health. These pollutions come from steam and kerosene itself. At the same time, harmful substances such as ink are dissolved in steam and kerosene, which can also cause considerable harm to the human body and the surrounding environment. The relevant contents will be explained in the following paragraphs. (To be continued)
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. .
