Film pollution is divided into three stages of film pollution, product pollution and post-disposal pollution. Process pollution. At present, most of the laminating equipment used in China is domestic equipment. The products below semi-automatic are mostly oily laminating, more manual labor, and the distance between the personnel and the film is close, but the price of this equipment is low, which is more suitable for the current labor force. Used by local manufacturers.
The oil-based film adhesive and its thinner contain a large amount of chemical diluents such as benzene and alcohol, which have a large odor, strong volatility and toxicity, and have caused health damage to many people in the industry. Reports are seen from time to time, and because of their chemical properties, they are extremely flammable, and are flammable in the presence of open flames or strong light, which is a great hidden danger of fire in factory production.
The combination of these two conditions, that is, semi-automatic mechanical and close manual operation, makes the operator suffer from dizziness, headache, skin redness and other discomforts. Those with excellent physical strength and those who are not allergic will also feel poor breathing, fatigue, and severe skin erosion The last neuritis causes muscle atrophy and even life-threatening.
Printing enterprises can not only consider issues from the perspective of cost, but must take into consideration social benefits, personnel health and other aspects, and take necessary measures to avoid or mitigate such pollution. Factory managers understand that laminating workers are generally reluctant to work or do not work long, even when there is a surplus of labor, working girls and wage earners are not looking for work.
Some factories use frequent substitution or rotation, and even adopt the method of recruiting new workers to the factory to work on the glazing machine for a few months to solve the problem of toxic and harmful substances on the personnel, but this is not the root of the problem. method.
Product contamination
Benzene and alcohols are highly volatile substances. Most of the volatiles are volatilized during the coating process and within a short time after the product is formed, but a small amount remains in the product, depending on the storage conditions and storage The time is extended and slowly evaporates.
The high-speed and high-efficiency production of modern industrial products has caused the residual substances to be quickly delivered to consumers along with the commodities. The odor and toxicity of these residual substances have polluted the environment of consumer survival to a certain extent and damaged consumer health. Today, the whole world is paying attention to the environmental protection, pollution-free and pollution-free products. This situation has to be changed.
Waste pollution
As we all know, paper products can be recycled, and paper products after film treatment are generally not directly recycled by paper manufacturers, and need to be separated after manual processing. If directly discarded, it will cause a new type of white pollution. Due to the large number of domestic waste paper recycling personnel, there is no or serious problem of waste pollution of coated paper products, but the potential existence of this factor does not disappear by itself.
