摘要/Abstract

摘要： 采用MERICAN 9505-50型光固化树脂在原有埋地钢罐内表面制作玻璃纤维增强塑料双层内衬,研究了光引发剂类型、光源功率、铺层结构、温湿度等对固化性能的影响,并与常用过氧化甲乙酮/钴液固化体系进行对比。结果表明:C190、C191二者均适用于此工艺,加入量为5‰,玻璃钢(FRP)光固化深度达12 mm,4 mm厚度成型仅需4 min(80 mW/cm²);与过氧化甲乙酮/钴液固化体系相比,光固化工艺固化速度提高十倍以上,固化度提高了8%,力学性能提高了20%~30%。

Abstract: Non-excavatedoil tank lining by UV curing is a molding process which was used for reforming in-service tank of gas station. Fiber reinforced plastics (FRP) properties were tested, including curing degree, bending strength, hardness and curing time. The results show that curing properties were influenced by photoinitiator (PI), UV power, layer structure, temperature and humidity, UV curing system is more efficient than cobalt/MEKP system. Both C190 and C191 are suitable for this process. With PI dosage, of 5‰, FRP curing depth is up to 12 mm, forming 3 mm FRP in 3 minutes, and curing efficiency can be improved more than ten times, curing degree can be increased 8%, bending strength can be increased by 20%~30%. MERICAN 9505-50 can be used for UV curing technology resin of non-excavatedoil tank lining.
