预发泡

以可发性聚苯乙烯（EPS）模样为研究对象，系统研究了珠粒粒径、预发泡时间、预发泡温度、模样成形蒸汽压力及成形时间对模样密度的影响。

In this paper , the effects of bead diameter , pre-expansion time , pre-expansion temperature , molding steam pressure and molding time of pattern on the density of expandable polystyrene ( EPS ) pattern were studied systematically .

随着珠粒粒径的增大、预发泡时间的增加、预发泡温度的升高、成形蒸汽压力的增加或成形时间的延长，模样的密度均呈减小趋势。

And along with the increasing of bead diameter , pre-expansion time , pre-expansion temperature , molding steam pressure or molding time , the density of expandable polystyrene ( EPS ) pattern decreased .

本试验研究了差压预冷、发泡聚苯乙烯箱和纸箱包装、0℃贮藏10天、保温车运输和常温下销售等方法对青花菜质量的影响。

The effects of forced-air cooling and outer packing with expanded polystyrene cases and corrugated boxes on broccoli quality during 10 days storage at 0 ℃, insulated vehicle transportation and distribution at ambient temperature were studied .
