聚乙烯基树脂

In this study, the electrical conductive composites (comprised of thermoplastic matrix resins-high density polyethylene, polyphenylene sulfide and polyarylethersuifone with cardo group, and conductive fillers-short carbon fiber, carhon black and graphite) are prepared and characterized in detail. The relation among composite structure and directalternating electric properties, some electric and magnetic parameters under X-band microwave and shielding effect, the mechanical behaviour are analysed. And furthermore, some relative experimental devices are developed.

本工作利用短切碳纤维、炭黑、石墨为导电填料填充热塑性树脂高密度聚乙烯、聚苯硫醚、酚酞型聚芳醚砜，制得具有良好导电性能和机械性能的导电性高分子复合材料，并以此为对象，研究了材料的稳恒电场和交变电场的基本特性与材料结构的关系，研究了在X波段微波场下的电磁参量及屏蔽效应，以及研究了复合材料及其基体树脂的力学行为，与此同时还建立了相应的表征测试手段。

This research is to study the effect of the characteristics of three wax-es, namely paraffin wax, carnauba wax and acrawax, on the ijection molding of carbonyl iron powder/low-density polyethylene mixtures.

本研究在於探讨三种蜡，即石蜡、巴西蜡、和胺蜡之特性，以及对於羰基铁粉╱聚乙烯树脂系统在射出成型过程中的影响。

96H LC 0,96 h LC 50 ,and 96 h LC 100 of twelve chemicals of phenol ,alkyl benzene and nitrobenzene,and three water samples to sword fish(\%Xiphophorus helleri)\% and rare minnow(\%Gobiocypris rarus\%) were tested.3. The phenol ic waste water was purified through the absorption of polyvingl pyridine.

介绍了含酚废水与聚乙烯基吡啶类树脂接触，酚类会吸附在树脂上，使废水得到净化，然后将吸附了酚类的树脂加热处理回收酚，与此同时，对树脂也进行了再生处理，再生后的树脂可循环使

PSP is composed of steel wire twined skeleton as the enhanced body and high density PE as the base. The enhanced body and the base are cohered together with a kind of high quality resin.

它以高强度钢丝左右螺旋缠绕成型的网状骨架为增强体，以高密度聚乙烯为基体，并用高性能的粘结树脂层将钢丝网骨架与内外层高密度聚乙烯紧密地连接在一起。

The invention adopts polyvinyl resin to substitute vinyl-polybutadiene, thereby decreasing the production cost, and increasing the mechanical property of high melt strength polypropylene resin get by only lead-in acrylics and the smooth finish of the product surface.

本发明采用聚乙烯树脂类代替乙烯基聚丁二烯。降低了生产成本，提高了单纯引入丙烯酸酯类所得的高熔体强度聚丙烯树脂的力学性能和制品表面的光洁度。
