The production process of FRP tanks
At present, the world's most used glass steel storage tank production methods have the following four kinds.Hand paste method: the main use countries are Norway, Japan, Britain, Denmark and so on.Jet method: the main use countries are Sweden, the United States, Norway and so on.Molding method: the main use countries, such as germany.RTM method (resin transfer molding): the main use countries are Europe and the United States, japan.
Filament winding, pultrusion and hot pressing, etc..
More than 90% of our FRP products are produced by hand paste. Other methods are pressing, winding, laminating and so on. Japanese hand cream still accounts for 50%. From the point of view of the world, hand paste still accounts for a considerable proportion, indicating that it still has vitality. Hand paste method is characterized by the use of wet resin molding, simple equipment, low cost, once more than 10m paste the whole product. The disadvantages are low mechanization, long production cycle and unstable quality. Our country has introduced extrusion, spraying, winding and other equipment from abroad. With the development of FRP industry, new process methods will continue to emerge.
