In the carbonization process, apart from the release of hydrogen, nitrogen, oxygen, there are methane, carbon dioxide, ammonia, hydrocyanic acid and so on. These gases must be quickly eliminated, otherwise they will condense and then stick to the fiber, which not only hinder fiber self-cleavage products excluded, but also bond fibers together and cause overheating.其他用户还搜索过:carbonization fossilcarbonizationcarbonization companiescarbonization definitionwhat is a threat to estuariescons of the green new deal
