The hazards of plastic dust, what kind of dust does plastic belong to

Inorganic dust, such as silica dust (quartz dust), asbestos dust, coal dust, metal dust, cement dust, abrasive dust, etc.;

Organic dust, such as cotton dust, hemp dust, bagasse dust, tea dust, feather dust, fur dust, plastic dust, etc. From the perspective of dust classification, female workers have more opportunities to come into contact with organic dust. However, female workers also account for a large proportion of inorganic dust operations such as asbestos dust, cement dust, and abrasive dust.

Except for the toxic effect of metal dust, there is not much gender difference in the harm of other kinds of dust to the human body. However, the harm of inorganic dust and organic dust to the human body is very different.

1) Inorganic dust. Represented by silica dust, the harm to the human body is mainly manifested in the fibrosis of the lungs, the alveoli are filled, and the ventilation function is impaired, so the X-ray chest radiograph is significantly different from that of normal people, and there are symptoms such as cough, chest tightness, and shortness of breath. There are few female workers engaged in silica dust operations, but in recent years, there are also many female workers in some stone and stone powder processing workshops in township enterprises.

Asbestos dust in inorganic dust is not uncommon for female workers to come into contact with, mainly for the processing or use of asbestos cloth, asbestos rope and asbestos thread. Asbestosis caused by stone dust is similar to silicosis caused by silica dust, but its onset is slightly slower. In the cement production and cement products processing industry, the production and use of grinding wheels in the industry, female cement dust operators and grinding wheel dust operators account for a large proportion, but these two types of dust have less harmful effects.

2) Organic dust. Female contact is more common. Represented by cotton dust, the harm to the human body is not like silica dust or asbestos dust can cause pulmonary fibrosis, but to make people get a disease called "cotton dust syndrome", that is, after a day of rest and then go to work, there will be chest tightness, chest tightness, a little wheezing or combined cough, the first day is heavier, but gradually reduced in the next few days, and long-term reversal can cause chronic bronchitis.

It is thought that this is due to an allergy to cotton dust. It can also cause a kind of "textile fever", which mainly occurs in people who come into contact with cotton dust for the first time, and it starts like a cold, and it gets better in 2 to 3 days, but it will attack later. These two diseases caused by cotton dust can also occur in operations such as hemp dust, tea dust, feather dust, and fur dust.

It takes more than 200 years for plastic to rot when buried in the ground, and it seriously damages the environment and pollutes the soil, posing a threat to animal survival.

Ordinary dust. Plastic refers to a plastic (flexible and skillfully dismantled high-quality) material with high molecular weight synthetic resin as the main component, adding appropriate additives, such as plasticizers, stabilizers, antioxidants, flame retardants, colorants, etc., or rigid materials formed by curing and cross-linking.

Dust refers to solid particles suspended in the air, and it is customary to have many names for dust, such as dust, dust, soot, mineral dust, sand dust, powder, etc., and these nouns have no obvious boundaries. In life and work, productive dust is the natural enemy of human health, and filial piety is the main cause of a variety of diseases.

Dust refers to the number of holes in the air with a diameter greater than microns, which can be used in daily life, but the more common dust is the dust generated by industrial production, and the bridge is extremely harmful to the human body. Inhalation of dust can cause pneumonia, silicosis, etc. Especially for people who work in chemical plants, frequent inhalation of dust may also cause serious diseases such as chronic obstructive pulmonary disease and lung cancer.

Many, the most important of which are:

1.The quality of the plastic regrind. The worse the quality of the plastic, the more balanced dust is generated.

2.The particle size of the plastic regrind. The smaller the crushing particle size, the greater the amount of dust generated.

3.Ambient humidity. When the ambient humidity is high, the amount of dust generated will increase.

4.The working efficiency of the powder tung crusher. The higher the efficiency of the pulverizer, the more dust will be generated.

5.The impact forces and vibrations generated during the crushing process. When the impact and vibration increase, so does the amount of dust generated.
