Like other things, there are defects in the film, which is the problem of pollution. Membrane fouling is divided into three stages: film coating process pollution, product contamination and post-disposal pollution.
1.Process pollution
At present, most of the laminating equipment used in China is domestically produced equipment. The semi-automatic products are mostly oil-based laminating, and there are many manual labors. The distance between the person and the film is close, but the price of the equipment is low, and it is more suitable for the current labor force. Used by regional manufacturers. The oily laminating adhesive and its thinner contain a large amount of chemical diluents such as benzenes and alcohols, which have large odor, strong volatility and toxicity, and have caused health damage to many people in the industry. Reports are reported from time to time, and because of their chemical properties make them extremely flammable, encountering open flames or strong light flammable, is a great hidden danger caused by fire in factory production.
The combination of these two conditions, that is, semi-automatic mechanical plus close-range manual operation, causes the operator to suffer from dizziness, headache, redness and other discomforts. The physical strength is very good, and those who are allergic to it will feel poor breathing and fatigue, and the skin of the severe person will be gorgeous. Terminal neuritis causes muscle atrophy and even life-threatening. Therefore, the author appeals that enterprises should not only consider problems from the perspective of cost, but also take comprehensive measures from the aspects of social benefits and personnel health to take necessary measures to avoid such pollution or mitigate such pollution. The managers of the factory understand that the film-coaters are generally unwilling to do or not to do long, even in the case of surplus labor, working girls, and wage earners who are not good at finding a job.
Some factories also use the method of frequent substitution or round-shifting, and even use the method of recruiting workers to work in the factory for several months to solve the problem of toxic and harmful substances to the personnel, but this is not the fundamental solution to the problem. method.
2, product pollution
Benzene and alcohols are highly volatile substances. Most of the volatiles are volatilized during the filming process and shortly after the product is formed, but a small amount remains in the product, along with storage conditions and storage. The time is extended and slowly evaporates.
The high-speed and high-efficiency production of modern industrial products makes the residual materials quickly conveyed to consumers. The odor and toxicity of these residual substances pollute the environment of consumers and damage the health of consumers. Today, the whole world is paying attention to the green, pollution-free and non-polluting nature of products, and this situation has to be changed.
3. Waste pollution
It is well known that paper products can be recycled, and paper products after film processing are generally not directly recycled by paper manufacturers, and need to be manually separated and then processed. If discarded directly, it will cause a new type of white pollution. Due to the large number of waste paper recycling personnel in China, there is no or no serious problem of waste pollution of coated paper products, but the potential existence of such factors does not disappear by itself.
