浙江省镇海县化工阀门厂在化工部设备设计技术中心站指导下,在上海石化总厂二分厂等单位协助下,试制生产了CSF型耐腐蚀增强聚丙烯隔膜阀,该阀经上海、天津等几十个单位使用,效果良好。该阀已于1983年11月通过技术鉴定。聚丙烯综合性能好,但存在着低温脆性、易老化、膨胀系数大等缺点,为了克服聚丙烯的不足,加入适量比例的玻璃纤维进行增强,可提高其机械强度和热变形温度。 CSF型耐腐蚀增强聚丙烯隔膜阀,系采用聚丙烯树脂与玻璃纤维在定型钢膜中,经注塑,机械车削后装配而成,密封膜片为聚全氟乙丙烯(F—46)制成。该阀的特点为:
Zhejiang Zhenhai Chemical Valve Factory, under the guidance of Equipment Design and Technology Center of the Ministry of Chemical Industry, with the help of the second branch of Shanghai Petrochemical Plant and other units, trial-produced and produced CSF corrosion-resistant reinforced polypropylene diaphragm valve. The valve passed Shanghai, Tianjin, etc. Dozens of units to use, the effect is good. The valve was passed in November 1983 technical appraisal. Polypropylene has good comprehensive properties, but has some shortcomings such as low temperature brittleness, easy aging and large expansion coefficient. In order to overcome the shortcomings of polypropylene, adding proper proportion of glass fiber can enhance its mechanical strength and heat distortion temperature. CSF corrosion-resistant reinforced polypropylene diaphragm valve, the Department of polypropylene resin and glass fiber in the stereotypes in the film, the injection molding, assembly after the assembly made of mechanical turning, the sealing membrane for the FEP made of F-46 . The valve features:
