Does using polyimide resin powder affect the air?

Polyimide resin powder in the sintering curing process, may produce some emissions, mainly including: 1. formaldehyde: due to the polyimide resin powder contains formaldehyde groups, so in the sintering curing, will release a small amount of formaldehyde exhaust. 2. ammonia: polyimide resin powder in the sintering curing process, may release a small amount of ammonia exhaust. 3. carbon dioxide: in the high temperature, polyimide resin powder will decomposition Carbon dioxide exhaust gas is generated. Precautions: 1. Temperature and time should be strictly controlled during the sintering and curing process to avoid generating excessive exhaust gases. 2. Necessary exhaust and protective measures should be taken to ensure the safety of the working environment. 3. Hazards: 1. Formaldehyde is a hazardous substance and is harmful to human health. Long-term exposure to formaldehyde may lead to respiratory diseases, cancer and other illnesses. 2. Ammonia and carbon dioxide are also harmful gases. Long-term exposure to these gases may cause headaches, coughing, shortness of breath and other uncomfortable symptoms. At the same time, the emission of these gases may also pollute the atmosphere and affect air quality.
During the sintering and curing process of polyimide resin powder, the main exhaust gases produced are carbon monoxide, carbon dioxide, nitrogen oxides, sulphur oxides, nitrates, organic gases and water vapour. Among them, carbon monoxide and carbon dioxide are mainly emitted by fuel combustion; nitrogen oxides and sulphur oxides are mainly generated due to the organic substances contained in the surface materials during sintering; nitrates are mainly generated due to the nitrides contained in the structural materials; organic gases are mainly generated due to the organic substances contained in the surface materials during sintering; and water vapour is mainly generated due to the water contained in the structural materials.
