一、pa6 bc304 尼龙6 /氯化钾复合材料的结晶与性能:
复合材料的结晶诱导时间:在研究PA6体系等温结晶过程中,发现聚合物结晶过程中两平行板之间的间距发生变化,体积会发生收缩,体积收缩过程中会引起法向应力变化,在结晶的初期法向应力能很快松弛,超过一定的时间后,该应力会聚集并迅速增大并随结晶的进行而发生突变,突变的时间体系相结构发生变化,Carrot和Zheng等在研究HDPE结晶过程也发现这种现象,他们认为可以用结晶法向应力(Ft)等于起始法向应力(F0)2倍所对应的时间t来表征结晶诱导时间.

三、pa6 bc304无卤阻燃尼龙6 复合材料的阻燃性能及热分解动力学研究:
The Research of thermal degradation kinetics and Flame Retardant Property of Halogen-Free Flame Retardant PA 6 Composite
Cheng Baofa, Zhu Xiangdong, He Qi, Zheng Tianxiao, Fan Guanghong
Beijing National Innovation Institute of Lightweight Co.,Ltd., State Key Laboratory of Advanced Forming Technology and Equipment, Beijing, 100083
Abstract: The different flame-retardants were mixed with nylon 6 by the twin-screw extruder to prepare the halogen-free flame retardant composites. It is found that the composite has a good property when titanate coupling agent reaches 2 wt% of magnesium hydrates and has a good dispersibility in nylon 6. When the ration of magnesium hydrates and micronized red phosphorus reach 6:4, the best synergistic flame retardant effect is found. The total content of flame retardant is reduced from 15 wt% to 14 wt% when 1 wt% organic montmorillonite is mix with nylon 6, and the composite could reachV-0 rate and the mechanical property improves obviously. The decomposition activation energy of of MH/HP/OMMT/PA6 composite reaches to 157.8 kJ/mol which shows a good thermos-stability.Keywords: Nylon 6; dispersibility; flame retardant; activation energy;thermostability.
五、pa6 bc304尼龙PA6 熔体在直排多腔挤出模内流动均匀性研究:
申振楠,王敏杰,刘奎,刘潮
(大连理工大学模塑制品教育部工程研究中心,辽宁大连116024)摘要:针对挤出成型过程中尼龙PA6熔体流动性差的问题,基于聚合物流变学理论和计算流体动力学数值分析,研究了尼龙PA6棒材直排6腔挤出模流道结构对熔体流动均匀性的影响规律。结果表明:影响熔体在直排6腔挤出模流道内流动均匀性因素的主次顺序为流道平直段半径、流道平直段长度、流道间距;获得了最优尼龙PA6棒材直排6腔挤出模具流道结构参数,数值分析结果表明熔体从主流道入口到各分流道出口处沿挤出方向压力降相近,流经各分流道的熔体体积流率相等。关键词:尼龙PA6;直排多腔;挤出模;流道结构;流动均匀性
六、pa6 bc304玻纤增强尼龙6振动摩擦焊接强度影响因素研究:
●Abstract: The eff ects of glass fi ber properties, processing methods and toughening agent content on the welding strength of glass fiber reinforced nylon 6 composites were studied. The results show that the retention length of glass fi bers processed by main feeding method is shorter than that processed by side feeding method, and the thicker the welding layer, the higher the welding strength. The welding strength of composites decreases with the increase of toughening agent content. For diff erent glass fi bers, the welding strength of composites is related not only to the properties of glass fi bers themselves, but also to the surface wetting agent of glass fi bers.

八、广业视角--利空笼罩 五月PC弱势延续 ??pa6 bc304
05月30日讯
??一、价格走势
??根据生意社监测的数据显示,五月PC市场延续弱势,截止5月30日,国内生产商、贸易商对拜耳2805的报盘价格平均在18833.33元/吨左右。
??二、原因分析
??PC上游双酚A五月整月盘面走势持续震荡偏弱。业者信心不足,交投走单迟缓,阻力较大,中间商让利走单,价格低位运行。下游工厂刚需采购,需求未见改善。场内观望气氛浓重,预计后市可能延续弱势整盘运行,对PC成本面支撑不佳。五月份是国内传统检修旺季,PC装置开工率一般,但供需矛盾的主旋律之下,库存不减反增。业者心态普遍看跌,外部消息面不稳定加剧市场消极心态。下游需求未见改善,PC报价弱势僵持。
??三、后市预测
??生意社PC分析师认为:五月份国内PC市场供需矛盾仍然突出,交投寡淡。外部消息面动荡加剧,报盘弱势僵持。预计近期走势很可能弱势难改。
