The three major pollution problems of laminating workers after printing

Like other things, there are defects in the film, which is pollution. The membrane fouling is divided into three stages: membrane fouling, product contamination and post-contamination pollution.

1. Process pollution

At present, most of the equipments used in China are home-made equipment. Most of the products below semi-automatic are oil-based films. There are many manual labors, and the distance between personnel and film is close to that of plastics. However, the price of such equipment is low, and it is more suitable for the current labor force. Is used by local manufacturers. The oily film adhesive and its thinner material 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. The report was reported from time to time, and because of its chemical properties, it was extremely flammable. It was a flammable fire in the event of a fire or bright light.

The combination of these two conditions, that is, semi-automatic mechanical plus close manual operation, the operator produces dizziness, headache, skin irritation and other uncomfortable conditions, physical strength is not easy to allergy will feel uncomfortable breathing, fatigue, severe skin erosion, The end of neuritis caused muscle atrophy and even life-threatening. Therefore, the author appeals that companies should not only consider the issue from the perspective of cost, but must comprehensively consider social benefits, personnel health, and take necessary measures to avoid such pollution or mitigate such pollution. Factory managers understand that coated workers are generally not willing to do or do long, even in the case of over-employed workers, working girls, and workers who are not easy to find a job.

Some factories use the methods of frequent substitutions or rotations, and even employ new recruits to enter the factory to work at the polishing machine for a few months to solve the problem of poisoning and harmful substances, 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 film coating process and in the short period after the product is formed. However, a small amount remains in the product, along with storage conditions and storage. The time is prolonged and it slowly volatilizes.

The high-speed, high-efficiency production of modern industrial products has led to the rapid transfer of residual substances to consumers. The smell and toxicity of these residual substances have to some extent contaminated the environment in which consumers live and harmed the health of consumers. While the entire world is concerned about the environmental protection, pollution-free, and pollution-free products, this status quo has to be changed.

3, waste pollution

As we all know, paper products can be recycled, and the paper products after the film processing are generally not directly recycled by paper manufacturers, and need to be manually separated and then processed. A new type of white pollution will result if it is directly disposed of. Due to the large number of waste paper recyclers in the country, there is no or no serious problem of pollution of coated paper products. However, the potential existence of such factors does not disappear by itself.
