The technology of the current method of recovering the vegetable foam box is much better. If you want to know more about it, you need to read the following detailed introduction carefully:
Introduction: Chemical recovery means that the vegetable foam box uses the methods of alcoholysis, hydrolysis, alkaline hydrolysis, and pyrolysis under certain conditions to differentiate into polyols and aromatic amines, carbon dioxide, etc., and then separates the fractions through distillation and other equipment. To achieve the purpose of recovery.
1. The alcoholysis method In the research on the chemical recovery of wastes from vegetable foam boxes, the alcoholysis method is the most active, and has achieved good economic and environmental benefits, which was the key recovery method at that time.
2. Alkali hydrolysis method Alkali hydrolysis method uses one or more mixtures of alkali metal hydroxides such as NaOH, LiOH, KOH, Ca (OH) 2 as differentiation agents, and quaternary amine salts or sulfates as activators. In a differentiator with crushed flexible foam, heat to 160 ° C under mixing to start the differentiation reaction, and keep mixing for 4 hours.
3. Pyrolysis There are two methods for the pyrolysis of vegetable foam boxes . One method is to crack in an inert gas air or an oxidizing atmosphere at a high temperature of 250-1200 ° C. The product is a gaseous and liquid mixture.
I have learned about the contents of the vegetable foam box in the future, and will be more helpful to everyone in the future, so that it can be more convenient when used. About the above common sense, I will briefly introduce this.



What are the methods of recovering vegetable foam boxes ? The current methods of recovering vegetable foam boxes are much better. If we want to know more about it, we need to carefully read the following detailed introduction:
Introduction: Chemical recovery means that the vegetable foam box uses the methods of alcoholysis, hydrolysis, alkaline hydrolysis, and pyrolysis under certain conditions to decompose it into polyols, aromatic amines, carbon dioxide, etc., and then separate the decomposed products through distillation and other equipment. Reached the purpose of recovery.
1. The alcoholysis method is the most vivid in the research on the chemical recovery of wastes from vegetable foam boxes, and has achieved good economic and environmental benefits, which is the key recovery method at that time.
2. Alkali hydrolysis method The alkali hydrolysis method is to use one or more mixtures of alkali metal hydroxides such as NaOH, LiOH, KOH, and Ca (OH) 2 as decomposition agents, and use quaternary amine salts or sulfates as activators. In the decomposer of the damaged flexible foam, heat it to 160 ° C under stirring to start the decomposition reaction, and keep stirring for about 4 hours.
3. There are two ways to pyrolyze the vegetable foam box .
One method is to perform cracking in an inert gas air or an oxidizing atmosphere at a high temperature of 250-1200 ° C. The product is a gaseous and liquid mixture.
After knowing the relevant contents of the vegetable foam box in the future, we will be more helpful in the future in the use, so that it can be more convenient in the use of time, about the above common sense briefly introduced here.
