Formulating of Recipe of β Crystal Form Nucleation of Polypropylene Resin;
PP树脂β晶型成核配方设计
The nanocomposites composed of polypropylene(PP),ethylene-propylene-diene terpolymer(EPDM) and nano-Mg(OH)2 particles were prepared by melt blend dynamic vulcanization method.
采用动态硫化法制备了聚丙烯/三元乙丙橡胶/纳米Mg(OH)2复合材料,通过力学性能测试、差示扫描量热仪(DSC)分析等手段,对纳米氢氧化镁填充EPDM/PP的力学性能以及结晶与熔融特征进行了研究,通过透射电镜考察了纳米Mg(OH)2在EPDM/PP体系中的微观结构。
Because the core (special copolyester) could be dissolved in alkaline liquor, after the core's being dissolved, the PP hollow fibers with hollowness of 30 % ~ 50 % and lower density were obtained .
采用复合纺丝法制备了以PP为皮层、以特殊改性共聚酯为芯层的皮芯结构复合纤维;然后,利用芯层在碱液中可水解的性质将芯层溶除,从而获得中空度为30％-50％的、密度更低的PP中空纤维。
Two kinds of robust PP mean absolute deviations M_1(a),M_2(a),(a∈ S~(p-1))and their asymptotic expressions are obtained,furthemore,the asymptotic distributions of M_1(a) and M_2(a) uniform for a∈S~(p-1) are derived which are supremums of the Gauss processes on S~(p-1).
对两类较稳健的PP平均绝对离差M_1(a),M_2(a),(a∈S~(p-1))进行了讨论,获得了它们的渐近表示式,并由此得到M_1(a),M_2(a)关于a一致地渐近分布为高斯过程的上界。
A intumescent paints with good adhesion for PP board was prepared by proper choice of resins,solvents, additives and flame retardants etc.
通过表面处理和选择合适的树脂、溶剂、助剂、膨胀型阻燃剂等,制备出用于PP板表面的膨胀型阻燃涂料。
