一、pa6 m2500i 尼龍6 /氯化鉀復(fù)合材料的結(jié)晶與性能:
復(fù)合材料的結(jié)晶誘導(dǎo)時(shí)間:在研究PA6體系等溫結(jié)晶過程中,發(fā)現(xiàn)聚合物結(jié)晶過程中兩平行板之間的間距發(fā)生變化,體積會發(fā)生收縮,體積收縮過程中會引起法向應(yīng)力變化,在結(jié)晶的初期法向應(yīng)力能很快松弛,超過一定的時(shí)間后,該應(yīng)力會聚集并迅速增大并隨結(jié)晶的進(jìn)行而發(fā)生突變,突變的時(shí)間體系相結(jié)構(gòu)發(fā)生變化,Carrot和Zheng等在研究HDPE結(jié)晶過程也發(fā)現(xiàn)這種現(xiàn)象,他們認(rèn)為可以用結(jié)晶法向應(yīng)力(Ft)等于起始法向應(yīng)力(F0)2倍所對應(yīng)的時(shí)間t來表征結(jié)晶誘導(dǎo)時(shí)間.

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 decomb 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 m2500i尼龍PA6 熔體在直排多腔擠出模內(nèi)流動均勻性研究:

(大連理工大學(xué)模塑制品教育部工程研究中心,遼寧大連116024)摘要:針對擠出成型過程中尼龍PA6熔體流動性差的問題,基于聚合物流變學(xué)理論和計(jì)算流體動力學(xué)數(shù)值分析,研究了尼龍PA6棒材直排6腔擠出模流道結(jié)構(gòu)對熔體流動均勻性的影響規(guī)律。結(jié)果表明:影響熔體在直排6腔擠出模流道內(nèi)流動均勻性因素的主次順序?yàn)榱鞯榔街倍伟霃?、流道平直段長度、流道間距;獲得了最優(yōu)尼龍PA6棒材直排6腔擠出模具流道結(jié)構(gòu)參數(shù),數(shù)值分析結(jié)果表明熔體從主流道入口到各分流道出口處沿?cái)D出方向壓力降相近,流經(jīng)各分流道的熔體體積流率相等。關(guān)鍵詞:尼龍PA6;直排多腔;擠出模;流道結(jié)構(gòu);流動均勻性
六、pa6 m2500i玻纖增強(qiáng)尼龍6振動摩擦焊接強(qiáng)度影響因素研究:
●Abstract: The eff ects of glass fi ber properties, processing bs 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 b is shorter than that processed by side feeding b, 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、廣業(yè)視角--供需失衡 PA66五月弱勢延續(xù) pa6 m2500i
05月30日訊
一.價(jià)格走勢
據(jù)生意社大宗榜數(shù)據(jù)顯示,5月份PA66市場延續(xù)弱勢整理走勢,供需失衡未見改善。截止5月30日,PA66主流報(bào)盤平均價(jià)格在27500.00元/噸左右,較月初有8.33%的跌幅。
影響因素分析:
產(chǎn)品:進(jìn)入五月以來PA66上游己二酸國內(nèi)市場走勢持續(xù)弱勢,庫存壓力一般但場內(nèi)跟進(jìn)消極。需求疲軟,交投寡淡,商家低價(jià)出貨。業(yè)者觀望氣氛濃重,操作空間有限。本月外盤純苯價(jià)格受到原油和消息面的影響先揚(yáng)后抑,國內(nèi)純苯價(jià)格則較為平穩(wěn)。市場報(bào)盤基本平緩,預(yù)計(jì)近期走勢需看下游需求;上游支撐不足,無法利好國內(nèi)牌號PA66報(bào)盤。
需求面:目前國內(nèi)PA66切片供需失衡,下游工廠拿貨持續(xù)疲軟。廠家受到來自成本面的壓力而開工偏低。市場買氣不足,業(yè)者看空心態(tài)較重,貿(mào)易商隨行就市,交投阻力較大。
后市預(yù)測:
生意社分析師認(rèn)為:五月份國內(nèi)PA66市場延續(xù)弱勢運(yùn)行,下游維持剛需采購,供需矛盾持續(xù),報(bào)盤弱勢下跌,預(yù)計(jì)近期PA66盤面可能會弱勢難改。
