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.

(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(duì)擠出成型過(guò)程中尼龍PA6熔體流動(dòng)性差的問(wèn)題,基于聚合物流變學(xué)理論和計(jì)算流體動(dòng)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(duì)熔體流動(dòng)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(dòng)均勻性因素的主次順序?yàn)榱鞯榔街倍伟霃?、流道平直段長(zhǎng)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(dòng)均勻性
六、pa6 k222-kgv4玻纖增強(qiáng)尼龍6振動(dòng)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--連塑減倉(cāng)反彈 空單謹(jǐn)慎持有 pa6 k222-kgv4
05月30日訊
盤面情況:L1909開(kāi)盤7855元/噸,最高報(bào)7920元/噸,最低報(bào)7780元/噸,收盤7795元/噸,較上一交易日-1.52%;成交量482460手,+87958手;持倉(cāng)660122手,+30144手,基差255元,+105元,9-1價(jià)差70元,-10元。
消息:日前山東省淄博、濟(jì)南、煙臺(tái)、青島等市、區(qū)分別發(fā)布關(guān)于擬“關(guān)閉淘汰一批”化工生產(chǎn)企業(yè)的公示通知。據(jù)不完全統(tǒng)計(jì)關(guān)閉淘汰的化工廠過(guò)1000家。
現(xiàn)貨市場(chǎng):國(guó)內(nèi)聚乙烯市場(chǎng)氛圍走弱,成交重心漲跌互現(xiàn)。企業(yè)方面,主流大區(qū)銷售公司開(kāi)單價(jià)穩(wěn)定,線性期貨下跌,商家態(tài)度謹(jǐn)慎,報(bào)盤部分下調(diào),僅少量貨緊資源仍有小漲。下游拿貨謹(jǐn)慎,實(shí)盤按需為主。截止上午收盤,華北地區(qū)調(diào)整幅度50-200元/噸;華東地區(qū)線性部分走低50元/噸;華南地區(qū)漲50-150元/噸。
倉(cāng)單庫(kù)存:交易所倉(cāng)單報(bào)2066手;處于歷史中位區(qū)域,今日-40手。主力持倉(cāng):主力合約前20名多頭持倉(cāng)為192122手,+7755手,空頭持倉(cāng)為241825手,+15787手,凈多持倉(cāng)為-49703手,-8032手。
總結(jié):原油高位回落、中美貿(mào)易戰(zhàn)加劇、塑料下游需求一般對(duì)連塑價(jià)格形成一定的壓制,但裝置檢修增多,兩油庫(kù)存回落則LLDPE的價(jià)格形成支撐。技術(shù)上看,L1909合約反彈受阻,成交量大幅上升,持倉(cāng)量也大幅增加,主力持倉(cāng)顯示,多方主力增倉(cāng)力度小于空頭主力增倉(cāng)力度,空方占優(yōu)。指標(biāo)MACD低位徘徊,紅柱收縮,KDJ指標(biāo)也在弱勢(shì)區(qū)域徘徊,顯示空方力量有所增加,后市關(guān)注7650一線的支撐力度。操作上,投資者手中空單可謹(jǐn)慎持有。
