The influence of forming process parameters of FRP tank
Writer:admin    Released:2018-06-30 09:15:45    Type:【L】【M】【S
The resin content of FRP tank is related to winding tension and curing pressure.Relatively speaking, the compressive property of winding materials has little relation with the content of resin, but the overmuch or insufficient content of resin will reduce the tensile and flexural properties.The influence of resin content on strength is directly related to the increase of thickness and the expansion of pores.In order to improve the appearance of products on the surface of current products often also coated with resin.If the coating is quite thick.Due to the different expansion coefficient between the product and the coating, cracking will occur when used outdoors.
Products after a tie, in order to accelerate the curing, tend to increase such temperature change of some operations must also note, because it can seriously affect the strength of products in general, must according to different curing section to determine the price corresponding to heating speed and strength to ensure that products are the highest.The type and dosage of curing agent are different, and the heating rate should be different.For some resin, slightly change the kind and amount of catalyst, will significantly impact on the performance of products, and other resin, of the variety and dosage of catalyst is not very strict.The sample selection of curing agent has a great influence on the strength performance of epoxy FRP, especially at ultra-high temperature.
