1. Ammonia is a poisonous gas with a stimulating odor, which is harmful to human eyes and respiratory organs. Leakage should be prevented, especiallyVacuum Heat Treatment of Fasteners  Prevent the human body from contacting with liquid ammonia, otherwise it will cause skin burns. 2. Frequently check and maintain the airtightness of the gas system of the device. The leakage of ammonia gas has an irritating odor, while the decomposition gas is colorless and odorless, but it is flammable and explosive gas. Therefore, in order to prevent leakage and avoid accidents, unqualified gas and waste gas must be vented to the outside.Vacuum sintering of transparent ceramics 3. Strict control of temperature is an essential condition for the full decomposition of ammonia, so it is necessary to pay attention to whether the temperature controller is working normally. If the temperature controller fails or the thermocouple is not in good contact, it will easily cause the inconsistency between the indicated temperature and the actual temperature, and even burn out if the temperature is too highVacuum sintered powder metallurgy parts Once the decomposition furnace and catalyst are found, the power supply should be cut off immediately for maintenance. The calciner must not exceed 850°C during the heating process. 4. Do not touch parts such as high-temperature surfaces with hands, arms and body.316L stainless steel vacuum brazing process
