Temperature and sunlight affect the storage time of unsaturated polyester resin. In fact, whether unsaturated polyester resin or other resins, the storage temperature is best at the current regional temperature of 25 degrees Celsius. On this basis, the lower the temperature, the longer the validity of unsaturated polyester resin; The higher the temperature, the shorter the validity period.
The resin needs to be sealed in the original container to prevent the loss of monomer volatilization and external impurities fall in. And the cover of the packing barrel of resin storage can not be made of copper or copper alloy, it is best to use polyethylene, polyvinyl chloride and other metal material cover.
Generally speaking, in high temperature, to avoid direct sunlight to the packaging barrel, but the storage life will still be affected, because in high temperature weather, the resin gel time will be shortened a lot, if it is not good quality resin, or even directly solidified in the packaging barrel. Therefore, during the high temperature, if the conditions allow, it is best to keep the temperature constant set at 25 degrees Celsius in the air conditioning warehouse, if the manufacturer does not prepare air conditioning warehouse, it must pay attention to shorten the storage time of resin.
Special care should be taken that the resin mixed with styrene must be treated as a flammable hydrocarbon to prevent ignition. The warehouse and workshop for the storage of this kind of resin must have very strict management, and do a good job of fire prevention and fire prevention at any time.
Unsaturated polyester resin in the workshop process must pay attention to the safety matters
1, resin, curing agent, accelerator are flammable, must pay attention to fire prevention, to separate storage, otherwise it is easy to cause an explosion.
2,There must be no smoking and no open fire in the production workshop.
3,Adequate ventilation must be maintained in the production workshop. There are two forms of workshop ventilation. One is to keep the indoor air circulating so as to eliminate styrene volatiles at any time. Because the styrene vapor is much denser than the air, the styrene concentration near the ground is also relatively high, so the exhaust vent in the workshop is best set near the ground. The other is to exhaust the operating area locally with tools and equipment. Such as Separate suction fans are set to drain the high concentration styrene steam discharged from the operation area, or exhaust the flue gas through the general suction pipe set in the workshop.
4, in order to cope with unexpected events, the production workshop should have at least two exits.
5, in the production workshop internal storage of resin and various promoters can not be too much, the best a small amount of storage.
6. Resin that has not been used but has been added with accelerant should be transferred to a safe location for scattered storage to prevent the accumulation of a large amount of heat in the accumulation to cause explosion and fire.
7, once unsaturated polyester resin leakage caused by fire, this process will discharge toxic gas harm to human health, so it is necessary to take emergency measures to deal with.
