Excuse me, during the sintering process of ceramic sintering furnace, the temperature inside the furnace is about 1800 degrees, and the temperature outside the furnace is normal temperature. What harm does this environment do to our human body? ..... I don't know what you mean by normal temperature Technically, it should be said that the surface is warming up. If it is generally understood as normal temperature, it means that the insulation performance of the kiln is very good. Harm of kiln to people: 1, various gases emitted from the glue discharging section of sintering, dust generated during sintering, influence on room temperature, and residual microwave generated by microwave oven are also harmful to people.
