                                                  Safety analysis of pearl foam production
Shanghai Guer Yi packaging Products Co., LTD
Shanghai Gueryi Packaging Products Co., Ltd. has been engaged in the production of pearl foam for more than 10 years, and safety accidents such as combustion and explosion occur in the same industry almost every year. In addition to the reasons for the company's management, it may be more important that it is directly related to the production process of pearl foam. The following is an analysis of the production process of pearl foam

Flow chart of pearl foam processing technology



Pearl foam processing technology: low density polyethylene as the main raw material and a moderate amount of talcum powder to join heating host - plasticizing dissolved by heating the host - using high-pressure pump injection shrinkage resistance agent and butane agent to form foam body approved by the water cooling - through the nose out - the blow up to fan cooling sizing, sizing and flattening traction - winding - put in storage
The whole process of physical change, there is no material brought on by a chemical reaction between the raw material property and the danger, but the analysis of the whole process, we analyze the most dangerous material is butane agent, (butane agent in life is the most common liquid in the lighter, butane agent is generally a high pressure liquid form in high pressure vessel, once the step-down release, rapidly expanding size and easy to burn) pearl foam is to use butane agent once the step-down release, the characteristics of rapid expansion, the volume filling the plasticizing dissolution of low density polyethylene and expansion molding, so bring a consequence is: 1: During the production process, butane agent after expansion and easy to burn and explode 2: During the product storage process, because the butane agent filled with the product will be released slowly, it is also easy to burn and explode. Therefore, we have produced what we said at the beginning of the article: almost every year, there are safety accidents such as combustion and explosion in the same industry
According to this characteristic of pearl foam cotton:
We suggest that all pearl foam factories should strengthen the following safety management:
1. Strengthen personnel training and safe production management of the factory (especially open fire is absolutely forbidden to enter the factory)
2. Strengthen the humidity management in the production workshop and warehouse. If the environment is too dry, it is easy to generate static electricity and cause accidents
3. Communicate with the pearl foam production equipment manufacturers to improve and improve the measurement and control process of the main blowers
