Production and use of explosion-proof membranes for mixers
Thread Content
The explosion-proof membrane used in the vinyl chloride conversion mixer in our factory is made from thick rubber in a simple manner; it works fine, but it isn’t up to standard. I’m curious to know how other manufacturers produce and use such membranes
Submit the process requirements to specialized manufacturers for procurement; safety cannot be taken lightly at all – if an accident occurs, it will be too late to regret it!
We use graphite explosion-proof membranes with a burst pressure of 0.089 MPa; they are manufactured by a company in Dalian. It must be used properly; otherwise, any problems that arise will be serious!
We made it ourselves; it’s probably designed to be small, so that the explosion-proof membrane remains intact after each explosion. :Lol, I firmly support standard usage.
Excuse me, I would like to ask about the lifespan of the graphite explosion-proof film on the 3rd floor
Once, our mixture exploded due to peroxide; at that time, there were only two explosion-proof membranes in place, which were manufactured by a company in Dalian. After the explosion, we added 5 more openings, all of which used PTFE sheets. On several occasions, the PTFE sheets bulged and leaked, but the explosion-proof membranes remained intact. Although this improved safety, the PTFE sheets aren’t reliable – they bulge and leak as soon as pressure exceeds a certain level. Every time there was a leak, we had to stop production to replace the sheets, which caused instability in our operations. So we changed back to using explosion-proof membranes primarily, while reducing the number of vents for pressure release. Things have been normal since then
Two explosion vents can be installed, switched using automatic valves.
Our factory uses 3mm PVC sheeting for production. It has been hyperchlorinated several times over the years, and it still works well.
Here, we use rubber sheets on the top and bottom layers, with two layers of asbestos sheets in between, which helps to prevent the risk of the pure rubber sheets from bulging. It has been used this way for many years.
The one we commonly use is also graphite, and the manufacturer is also in Dalian.
We use the one from Dalian University of Technology, by Su Shiyi. Explosion-proof films cannot be taken lightly; if an accident occurs and an improper one is used, severe penalties may be imposed. If it’s legitimate, you won’t be held responsible in case of an accident; don’t try to save money, as this is where liability issues arise. It’s for your own good as well as for the benefit of the organization.
