201不饱和聚酯树脂是专门为离心浇铸成型玻璃钢管道(HOBAS管)设计的结构层树脂,是低粘度,中等反应性的邻苯型树脂。
HCH-201 unsaturated polyester resin is designed for centrifugal casting molding glass pipe (HOBAS pipe) design of the structure layer resin is a low viscosity, medium reactivity of o-benzene resin.
由此认为注射充模时,熔体流动层应分为二层:高粘度流动层和低粘度流动层。
The spherulitic diameter varies markedly in the interface. During mold filling process, the flow layer should be divided to two layers:high viscosity molten layer and low viscosity molten layer.
