塑料编织袋工艺指标全文(可编辑)

塑料编织袋工艺指标全文塑料编织袋工艺指标塑料扁丝,塑编行业简称:扁丝,也有称为切割纤维,它是生产塑料编织物的基本材料,扁丝由特定品种的聚丙烯,聚乙烯树脂经熔融挤出成膜,然后,纵向分切成条,诸条同时加热牵伸取向后定型,最终卷绕成扁丝纱锭,供织造编织物扁丝工艺包括:原料改性,共混,着色,填充,配制,防老化,防降解问题,挤出过程的温度,压力,流量调节控制及挤出过程的流变行为,功耗,产率问题,牵伸过程的牵引比,吹胀比,牵伸比,结晶冷却,取向,热处理定型问题,卷绕过程中的成型及纱锭的质量检测等技术问题.扁丝工艺,又称造纱工艺,它是塑料编织物生产的第一道工序,也是最重要的一道工序? 扁丝生产工艺方法按成膜方法分有两种,管膜和平膜,按成膜后冷却方式分有,空冷,水冷和间冷,按牵伸加热方式有热板,热辊,热风,按纱锭卷绕成型分有,集中摆线卷绕,单锭力矩电机卷绕,磁力矩卷绕.3-1.扁丝生产工艺技术指标主要分四类:3-1-1.是物化改性指标,主要有共混改性,混配比,功能助剂添加比,废旧再生料掺混比3-1-2.是物性流变指标,主要有牵伸比,吹胀比,牵伸比,回缩比3-1-3.是机械性能指标,主要有拉断力,相对拉断力,断裂伸长率,线速度,线密度偏差3-1-4.是公差尺寸指标,主要有扁丝厚,扁丝宽等.3-1-1.改性混料比及百分率: 扁丝生产工艺方法按成膜方法分有两种,管膜和平膜,按成膜后冷却方式分有,空冷,水冷和间冷,按牵伸加热方式有热板,热辊,热风,按纱锭卷绕成型分有,集中摆线卷绕,单锭力矩电机卷绕,磁力矩卷绕.扁丝原料中常添加一些改性剂或是功能母料及废旧再生料等,可用两种指标.3-1-1-1.混料比,某添加组分和主要原料的重量比例称混料重量比3-1-1-2.添加百分率,某添加组占总体各组的重量百分数,称添加重量百分率.3-1-2.流变牵引比,吹胀比,牵伸比,回缩比:3-1-2-1.牵引比是挤出膜牵引速度与从膜口挤出速度之比,它不仅用于平膜,也用于管膜,通过控制牵引比,使膜在牵引方向上略有取向作用.牵引比的控制是控制挤出膜冷却后的厚度唯一有效的手段.因为一台挤出机的模口间隙基本固定,调节量较小,一般情况下,牵引比保持在4-8为宜.3-1-2-2.吹胀比,吹塑时,管膜吹出的膜泡直径和原来的模口直径的比,叫吹胀比.显然平膜没有吹胀比问题.从理论上看,吹胀比越大,则薄膜的横向拉伸定向作用越好,拉伸强度越好,但实际上产中不能太高,以免引起蛇形摆动,均匀程度下降,膜厚不等,出现皱褶等.一般情况下吹胀比控制在2.0-3.5之间,最大不超过8位宜.3-1-2-3.牵伸比,扁丝牵伸时,单位长度分割丝坯丝所牵伸的长度倍数,或者描述为牵伸二牵速度与牵引一牵速度的比值为牵伸比.牵伸比是扁丝生产中最重要的工艺指标.牵伸比也称牵伸倍数,拉伸比.扁丝的牵伸是在熔点温度以下进行的单向拉伸,拉伸过程是取向过程,以便扁丝获得高强度和其他物理机械性能.一般情况下,牵伸比控制在4-7倍,特殊需要的扁丝,牵涉比柯达11倍.3-1-2-4.回缩比,是指扁丝牵出速度和牵引速度的比值.从生产工艺需要上看,牵出速度要低于牵引速度,给边丝二次加热定型一个回缩量,使扁丝内应力消除,获得较强的拉力和优良的伸长率.回缩比,又称定型比.一般情况下,回缩比在0.96-0.99之间.3-1-3.扁丝线密度,相对拉伸负荷,断裂伸长率:3-1-3-1.扁丝线密度,是表征线性物体单位长度的质量.线密度越大,拉断力越大.在塑编中,扁丝的线密度是衡量塑料编织物总体强度的基本要素.按GB/T8946中附录A的规定,用纱框测长仪去100M扁丝,称重精确到0.1克.3-1-3-2.相对拉伸负荷,又称相对拉断力,是指每tex的扁丝的拉断力,对于每根扁丝,由于它的密度和厚薄各不相同,因而拉断力不同.但是相对拉伸负荷大小基本上趋于相近.因为相对拉伸负荷是与扁丝宽度和厚度无关的物理强度指标.它的大小取决于原料的温度,牵伸比,定型,冷却,结晶等因素.国标中规定相对拉断力大于等于0.32N/tex.3-1-3-3.断裂伸长率,是指扁丝拉伸时有效标线部分两夹具间拉断时长度增加量与初始有效标线部分两夹具间长度的百分比,断裂伸长率是衡量扁丝韧性弹性指标.具有较大的断裂伸长率,表征扁丝抗冲击时有一定的单性伸长,不会立即脆断.因而断裂伸长率大,在同等拉断力条件下,其跌落试验次数可能较多.国标中要求断裂伸长率为15-30%.3-1-4.扁丝宽与厚:3-1-4-1.扁丝宽度,是指分割丝经过牵伸后的宽度,它决定了编织物的编织密度.对于塑料编织袋和复合塑料编织袋,国标中推荐了三种常用编织密度径密*纬密,即36*36,40*40,48*48根/10cm.这三种编织密度也适用其他编织物,按这三种编织密度,扁丝的宽度理论计算为:2.78mm,2.5mm,2.08mm.在生产扁丝过程中要按客户要求的编织密度控制扁丝的宽度3-1-4-2.扁丝厚度,是指分割丝牵伸后的厚度.厚度决定了编织布单位面积重量.同时,如果扁丝宽度已经确定,扁丝的厚薄就是扁丝线密度的决定因素.3-2.编织袋编织工艺指标:3-2-1.编织密度及编织密度公差.3-2-1-1.编织密度是指100mm×100mm编织物内,经纬纱的根数.国家标准GB/T8946-1998中规定,"将袋摊平,在袋子的上,下两个对角处圈定100mm×100mm两方块,方块外边与袋边线相距100mm,目测方块的经,纬根数,取平均值,计数时当讫点最后不足一根时,按一根计."国家标准中规定了编织密度的同时,规定了密度公差.编织密度主要取决于包装产品,由用户决定常用的编织布密度是36×36根/10cm,40×40根/10cm,48×48根/10cm3-2-1-2.编织密度公差编织密度公差是指比给定标准编织密度多处或减少扁丝的根数.3-2-2.编织布单位面积质量编织布的单位面积重量是以平方米克重数来表示的,是编织布的一项重要技术指标.平方米克重数主要取决于经纬密度和扁丝的厚度,平方米克重数影响编织布的拉伸强度,载荷能力,平方米克重数是生产企业控制成本的一个主要环节3-2-3.编织布拉伸负荷拉伸负荷也称抗拉强度,拉伸强度.对于编织布克承受经向和纬向两个方向的拉伸负荷,故称经向,纬向拉伸负荷3-2-4.幅宽各种编织布幅宽直接影响制袋工序.对于筒布用折经表示幅宽,折经等于圆周长的一半幅宽回缩率,所有编织布织造卷取后的宽度,在展卷切割,印刷,缝合后,制成袋子的宽度都要略小于卷取时的宽度,我们称幅宽回缩3-2-5.手感PP扁丝编织物手感较厚实,挺阔,粗硬些HDPE扁丝编织物手感较软,润滑,不致密在PP扁丝料中添加钙质母料,手感挺阔,PP中少加HDPE会使其柔软些扁丝窄,编织的平,手感柔软,扁丝宽,编织布时折叠丝多,手感粗糙.3. 塑料编织工艺指标:3-3.编织袋涂复工艺指标GB/T8947-98和GB10803-89分别规定了涂复袋和涂复布的技术质量标准.它们有相同之处,也有不同之处,原因是对编织袋和编织布的应用要求不同,指标也略有不同.1998年修改为推荐标准后,比原来的GB8947-88更科学,更完善3-3-1.尺寸系列及公差3-3-1-1.复合塑料编织袋复合塑料编织袋的有效宽度系列是450-700mm,每50mm为一个档,宽度公差为±15至-10mm.袋的有效长度供需双方决定,公差为±15至-10mm,复膜厚度公差为±0.005mm3-3-1-2.复合塑料编织布编织布的宽度在2m以下每匹布为100m或是200m,宽度公差为0至+10mm,长度公差不允许负偏差.宽度2m以上每匹布为50m 或是100m,宽度公差为0-20mm,长度公差不允许负偏差3-3-1-3.单位面积质量及机械强度编织布涂复后的单位面积质量和拉伸负荷,剥离强度.编织袋剥离强度为3.0N/3cm,编织布剥离强度为2.5N/3cm.有一种实验剥离力的方法,那就是用胶粘带贴于涂复的膜上,然后撕拉胶粘带,不能把编织布和膜分开为合格,即达到了剥离强度.这种方法非法定检测效力3-4.编织袋制袋工艺指标: 编织袋制袋工艺是塑编的最后一道工序,它包括,印刷,切割,缝合,打包等几个主要环节3-4-1.缝制工艺指标3-4-1-1.缝合强度指标这项指标是制袋的最重要,最关键指标.在塑料编织袋GB/T8946和复合塑料编织袋GB/T8947国家标准中,明确了缝边向和缝底向,的拉伸负荷.影响缝合强度的主要因素是缝合线的种类和型号,针距大小,线迹,卷边或折边缝合线到袋边的尺寸,热切和冷切方式等.塑编企业应当制定这些影响因素的内控指标.对于集装袋,国家标准中规定,主体连接部的抗拉强度必须达到基本强度的67%以上,底部连接部的抗拉强度必须达到基本强度的42%以上.对于插口水泥袋的上封口,建议视同缝底向强度处理,对于纸袋缝底向的强度,一般是达不到指标的,故建议改为糊底袋.对于复膜冷切割袋,建议采用卷边处理,因为冷切边缘的缝线可能从经丝中连同纬丝撕出.对于无强度要求的编织袋上口锁边一周,针距可密,线可细3-4-1-2.尺寸公差对于塑料编织袋和复合塑料编织袋的长度和宽度公差同样是+15mm和-10mm.对于不符合宽度公差的筒布,在制袋工序中筛出,等待处理.对于粘中缝袋,长度公差是指缝合后的有效长度,剪切时留做缝.做缝量的大小由卷边,折边,上口内折边的具体情况确定.集装袋的尺寸公差是: 1m以下为20mm,1m以上是30mm3-4-1-3.印刷图文塑编印刷主要是凸版印刷,印刷图文位置公差,印刷图文清晰度,印刷图文色彩等.塑料产品国家标准中没有明确规定,有的标准中仅要求印刷清晰.因而塑编企业要根据用户要求制定企业印刷标准.制定企业标准时,要考虑自己印刷设备种类,印刷油墨种类,印刷能力等.BOPP凹版印刷有待标准规范3-4-1-4.外观质量塑料编织袋,复合塑料编织袋,集装袋,水泥袋,所有外观质量欠缺并非都是制袋工序造成的.但是,制袋工序是最后一道工序,也是质量把关的最后一道工序3-4-2.粘合工艺指标3-4-2-1.粘合强度指标塑编产品的国家标准中没有明确规定粘合强度指标.因而塑编企业可以根据用户要求和相关标准来制定企业标准.我们推荐按国家标准GB/T8947中的粘合向拉伸强度来制定企业标准.它不仅适用于各种粘接剂,也适用于各种粘接剂粘接中缝.影响粘接力的主要因素是粘接物的粘接力,搭接宽度,基材对粘接物的亲和力等3-4-2-2.搭接宽度用熔融树脂粘接,如果原料的温度选择适当,粘接后的强度应达到基材强度的80%左右3-4-2-3.熔融树脂的选择对于聚乙烯为基材的涂膜布可以用涂膜级聚乙烯,因为它们的相容性比较好.对于聚丙烯为基材的涂膜布,可以用涂复级聚丙烯或是专用聚丙烯中缝料,它们的熔融指数为:16-20g/10min.我们希望中缝粘合PP料比扁丝PP料的熔点温度低10℃左右,防止编织布热氧老化3-4-2-4.适用PP中缝粘接料时.挤出机的挤出温度可控制在260-280℃之间,适用PE中缝粘接料时.挤出机的挤出温度可控制在255-265℃,不同树脂,不同设备,可作适当调整.挤出流量控制依粘合速度而定,挤出膜厚0.05-0.12mm即可3-4-2-5.粘结剂的配制粘接剂用于中缝较少,主要用于糊底.粘接剂的配方,配制工艺,配制设备.应用方法都影响它的质量和粘接力.配方的主剂和固化剂是分别提供给用户的,用户现场配制.主剂和固化剂混合后产生交联固化,这个化学反应过程在常温下进行的比较缓慢,升温快速固化.因而配制量不要超过用量太多,配制后低温储存,储存时间不要太长,储存时密封.例如某配方:200L乙酸乙酯和25kgUlite3076粒子搅拌8h,配成母液,然后添加凝固剂和增稠剂,再搅拌5min,配成粘接剂,用于粘接中缝或糊底3-4-3.热封焊接与方阀底口工艺指标目前,世界上最先进的制袋工艺不是缝制,也不是粘合,而是热封焊接3-4-3-1.热封焊接工艺方法热封焊接的设备类似于纸袋的糊底机,只是把糊底部分改为热封焊接,热封设备首先把涂膜筒布印刷切割,再把它的上下口折叠.用400℃左右的热风焊接阀和加强片.这个技术关键是焊接加强片3-4-3-2.影响热封性的因素涂膜和基材的充分粘合是前提,如果剥离强度不足,热封焊接后,会产生布膜分离现象.这就要求涂膜表面必须进行适度的氧化,提高剥离强度.过度的氧化也会产生不良后果.加热加压的树脂表面是相互融合性减弱3-4-3-3.方地阀口袋的质量标准方底阀口袋的质量要求要比一般复合袋高,它是一种国际流行的高强度包装袋.目前,尚无统一,适用于各种物料包装的国家标准.GB9774-1998中,仅规定了适用于水泥包装的纸袋糊底或纸/塑袋糊底的一些质量指标3-4-3-4.各种封口强度比较编织布/纸复合缝口袋,无论是折边,卷边,包边,其强度都是最低的,它的拉伸强度只有50N-150N/5cm编织布/膜缝口袋,这其中包边袋强度最低,折边袋其次,卷边袋最好.GB/T8946/8947要求缝底向强度,TA型袋250N/5cm,A型袋300N/5cm,B型袋300N/5cm,C型袋350N/5cm.它的强度比编织布/纸复合缝口袋高方底阀口糊口袋,它的强度可按GB/T8947的粘合向强度执行,即TA型袋300N/5cm,A型袋350N/5cm,B型袋400N/5cm,C型袋400N/5cm.它的强度略高于编织布,编织布/膜缝口袋方底阀口热封焊接袋,它的强度最高.足够的搭接量,其强度可和基材相同.它是目前国际上最流行,强度最高的袋型3-4-4.缝纫线的技术指标3-4-4-1.塑编用棉线和涤纶线技术指标塑编缝合用的棉缝纫线按国家标准GB/T6835-1997和涤纶缝纫线国家标准GB/T6834-19973-4-4-2.线密度tex和英制支数Ne的选择线密度是衡量细长物单位长度上的质量标准.对于缝纫线可视为线的粗细.对于涤纶线和棉线而言,由于涤纶比棉线质重,故等同线密度时.同等股线和黏度前提下,涤纶线比棉线细些.这样选择涤纶线为29.9tex20Ne时,改用棉线时,最好先用线密度小一点的18tex32Ne防止线通过针孔困难衡量线密度的方法有:特克斯tex:1000米纱在公定回潮率时的质量克重数旦尼尔D:9000米纱在公定回潮率时的质量克重数公制支数Nm:在公定回潮率时一克重的纱所具有的长度米数英制支数Ne:在公定回潮率时一磅重的纱所具有的长度米数.每绞长等于840码回潮率是指纱线:烘前重量-干燥重量/干燥重量比值的百分数.烘干温度在105-110℃以内,烘至恒重目前,有的缝纫线供应商仍沿用英制指数Ne表示线密度如:20s/2*3,表示英制20支纱共6股3-4-4-3.股数,单线断裂强度,捻度,捻向股数:每条线由几股捻成,一般由2-12股捻成单线断裂强度:按GB2543-81测试单线的拉断力,用牛顿N表示捻度:每10cm长线的单股拧劲圈数初捻:没有合股前的单股捻度复捻:合股的捻度捻向:线拧劲方向,顺时针为S,反时针为Z3-4-4-4.线的外观质量及长度公差:塑编用棉缝纫线和涤纶缝纫线国家标准GB/T6835-1997和GB/T6834-1997中规定了它的外观质量及公差塑编企业用边丝或是裂膜丝生产的缝纫线,线密度150tex以上,外观无毛刺,纱锭无掉套4.编织袋质量标准:4-1.塑料编织产品质量检测及标准:塑料编织质量检测不应该简单的为产品质量的检测和把关,应该是全过程的质量检测,包括原料检测4-1-1.塑料编织袋的检测项目,方法及标准GB/T8946-1998规范了塑料编织袋的检测项目,技术要求,试验方法,检验规则及标志,包装,运输,储存要求.这个标准适用于聚丙烯,聚乙烯树脂为主要原料,经挤出,拉伸成扁丝,再经织造,制袋而成的用于包装粉状或颗粒固体物料及柔性物品的塑料编织袋,4-1-1-1.产品分类品种:按主要构成材料分为聚丙烯编织袋,聚乙烯编织袋.按缝制方法分为缝底袋,缝边底袋型号:编织袋的型号,允许装载质量,线密度,经纬密度规格:按编织袋的有效宽度分为,450,500,550,600,650,700mm4-1-1-2.耐热性从编织袋上取经向,纬向试样两块,长300mm,宽20mm.将其表面重叠起来,在上面施加9.8N的负荷,放入80℃的烘箱内1h,取出后立即将两块重叠试样分开,检查表面有无粘着,溶痕等异常情况4-1-1-3.卫生性能指标:

浅谈塑料编织包装发展

浅谈塑料编织包装发展

浅谈塑料编织包装发展Chen Peizhong;Wang Kejian【摘要】编织包装技术由来已久,从古代的草编,竹编演变到后来的麻袋、布袋再到当前的塑料编织袋,可以说,通过编织对物品进行包装深受大家的青睐.本文从塑料编织袋的选材、加工过程,应用和围家标准以及发展等几方面进行介绍,阐述塑料编织包装的发展应用.【期刊名称】《塑料包装》【年(卷),期】2019(029)003【总页数】5页(P25-29)【关键词】编织;塑料包装;发展应用【作者】Chen Peizhong;Wang Kejian【作者单位】;【正文语种】中文一、引言塑料编织袋,又称蛇皮袋。

我国从 19世纪60年代末开始出现塑料编织袋,凭借自身使用方便和价格低廉的特点,它发展的十分迅速,从刚开始的单一普通高密度聚乙烯(HDPE)塑料编织袋,发展到目前以高密度聚乙烯(HDPE)、低密度聚乙烯(LDPE)、聚丙烯(PP)和聚酯(PET)为原材料的数十种规格的塑料编织袋。

无论是在农产品包装还是在建筑包装上都能看到它。

甚至在食品包装上,也闪现着它的身影。

目前的塑料编织袋的工艺流程主要是把原料通过挤出、拉伸成扁状丝带,再经织造、制袋,最后经过检验合格后流入我们的日常生活。

二、编织工艺简介编织工艺历史极其悠久,主要是使用长条扁状的材料经过规律性交织、组合来制作出想要的图纹和形状的工艺。

传统编织工艺所用的材料主要是天然的植物纤维,如茎、叶、枝条等。

不仅具有取材方便、用途广泛的优点,而且无论是取材或是产物都具有环保这一特性。

目前编织工艺按其用料来分,可以分为传统的竹草编、织锦编以及近代出现的塑料编织;按技法分,可以分为平织、斜织和朱子织。

1. 按用料分竹编和草编拥有悠久的历史,伴随着人类的出现而出现。

竹编所用的材料为竹丝,其断面皆为矩形。

竹编对于材料的粗细和厚薄都有严格的要求,主要工艺为起底、编织、锁口。

随着科技的发展,目前竹编最为重要的作用已经不是用来承载或是包装物品,而是其中蕴含的文化价值。

1、塑料编织袋(无复膜编织袋)它的生产工艺流程是:编织布通过印刷,切割,缝制,成为编织袋。

依据所用的设备不同,可先切割后印刷,也可先印刷后切割。

自动切割缝纫可连续完成印刷,切割,缝纫等工序,也可制成阀口袋,放底袋等,对于平织布可进行中缝粘合后制袋。

塑料编织袋制袋工艺指标主要是外型公差尺寸,缝底向和缝边向的拉断力,印刷油墨的清晰度和印刷后其他部位的清洁度,版面位置准确度,缝合线迹,针距,及缝合脱针,断线等缺欠的要求。

2、复合塑料编织袋二合一、三合一等复合塑料编织袋的生产工艺流程是将编织布,涂复料和纸或膜,进行复合或涂复。

得到的筒布或片布,筒布可以进行切割、印刷、缝合、制成普通的缝底袋,也可以打孔、折边、切割、印刷、缝合,制成水泥袋,得到的片布,可以中缝粘合,印刷,切割,糊底,制成糊底袋。

也可以焊接,卷取,制成篷布、土工布复合制袋工艺关键是复合。

涂复的原理是把树脂在熔融状态下涂于基材编织布上。

仅把熔融树脂涂覆到编织布上并立即冷却,得到二合一编织布。

如果复合时,熔融树脂膜夹在编织布和纸或是塑料膜中间时,然后冷却得到三合一编织布涂复可以对平织物单面涂复得到片布,也可以对筒布双面涂复,得到涂复筒布。

涂复后的编织布可以印刷、切割、缝合制成各种袋型,宽幅涂复布也可卷取作为篷布出厂3、各种编织布平织布可以涂复或不涂复生产篷布,土工布等,圆筒布也可以破幅后涂复或是不涂复生产篷布或是土工布等一、塑制造粒流程简述将聚丙烯粉料、各种添加剂与活化好的碳酸钙按一定比例,按先后顺序倒入高搅机内,由低速到高速搅拌一定时间后放入料斗内,经喂料螺杆输送,使物料从加料口进入机筒,经机筒和螺杆的熔融塑化,连续稳定地挤出料条,料条经水槽冷却定型,经吸湿风机吸湿,风机●冷却,料条进入切粒机切粒,经振动筛筛选,由输送风机输送进入沸腾床沸腾干燥处理,然后进入料池,再由上料机把料池内的料吸入储料罐,粒料经检验合格后,定量包装完成整个生产过程。

塑料扁丝一、扁丝拉伸流程简述原料进入挤出机后,经190-250℃的外部加热和螺杆与机筒的互相剪切下,物料在几乎全部塑化完毕后,被定量、定压挤出。

经过膜头成型,成为熔融状的薄膜进入冷却水中。

经冷却后,薄膜被刀片切割成胚丝。

胚丝在温度较高的烘箱中被高倍拉伸直至形成扁丝。

然后扁丝在热辊上热定型,在低牵引速度的情况下予收缩,并被冷辊在低温下进行处理,最后经磁盘差动式张力收卷系统收卷成型。

生产的主要工艺指标●扁丝生产工艺技术指标主要分四类:●1、是物化改性指标,主要有共混改性,混配比,功能助剂添加比,废旧再生料掺混比;2、是物性流变指标,主要有牵伸比,吹胀比,牵伸比,回缩比;3、是机械性能指标,主要有拉断力,相对拉断力,断裂伸长率,线速度,线密度偏差;4、是公差尺寸指标,主要有扁丝厚度,扁丝宽度等。

三、圆织布基流程简述●首先从经纱架上的每排纱锭下引出经纱,经纱架瓷孔--第一长竖形板--压线棍--送径导棍--导丝棍--第二长条竖形板--导丝棍--磁孔--张力杆--棕丝--圆钢扣--定经环--预留布基。

把纬纱装入梭库中,开动机子后,在梭子推动装置的推动下使梭子作圆周运动,在经纱供应系统与梭子推动装置的紧密配合下,●编织成圆筒型平织物。

编织物被织机顶部的牵引装置向上牵引,经过导向辊以后,被经纱架后的收卷装置缠绕,当缠绕卷直径达1.2米左右时,进行卸卷,送下道工序。

塑料圆织布基生产主要工艺指标①编织密度及编织密度公差编织密度是指100mm×100mm编织物内,经纬纱的根数。

国家标准中规定了编织密度的同时,规定了密度公差。

编织密度主要取决于包装产品,由用户决定。

常用的编织布密度是36×36根/10cm,40×40根/10cm,48×48根/10cm。

②编织密度公差编织密度公差是指比给定标准编织密度多处或减少扁丝的根数。

③编织布拉伸负荷.拉伸负荷也称抗拉强度,拉伸强度.对于编织布承受经向和纬向两个方向的拉伸负荷,故称经向,纬向拉伸负荷④编织布单位面积质量编织布的单位面积重量是以平方米克重数来表示的,是编织布的一项重要技术指标.平方米克重数主要取决于经纬密度和扁丝的厚度,平方米克重数影响编织布的拉伸强度,载荷能力,平方米克重数是生产企业控制成本的一个主要环节.⑤幅宽.各种编织布幅宽直接影响制袋工序.对于筒布用折经表示幅宽,折经等于圆周长的一半.幅宽回缩率,所有编织布织造卷取后的宽度,在展卷切割,印刷,缝合后,制成袋子的宽度都要略小于卷取时的宽度,我们称幅宽回缩⑥手感.PP扁丝编织物手感较厚实,挺阔,粗硬些;HDPE扁丝编织物手感较软,润滑,不致密。

在PP扁丝料中添加钙质母料,手感挺阔,PP中少加HDPE会使其柔软些。

扁丝窄,编织平,手感柔软,扁丝宽,编织布时折叠丝多,手感粗糙。

四、涂膜流程简述●涂复的原理是把树脂在熔融状态下涂于基材编织布上。

仅把熔融树脂涂覆到编织布上并立即冷却,得到二合一编织布。

如果复合时,熔融树脂膜夹在编织布和纸或是塑料膜中间时,然后冷却得到三合一编织布,涂复可以对平织物单面涂复得到片布,也可以对筒布双面涂复,得到涂复筒布。

具体来说:挤出机经过加热后,将聚丙烯物料熔融,经模头挤出成型与生产线上圆筒型塑料编织布挤压复合、冷却定型为涂膜布基。

布基从退卷架经过第一导向、第一预热到第一面涂膜后,通过生产线上的十字翻转架,将布基翻转180度,使未涂面朝上,布基再通过第二导向、第二预热、第二涂膜从而完成双面涂膜,保证不停机连续生产。

塑料涂膜布基生产主要工艺指标●涂复工艺指标主要是温度,压力,厚度的控制,涂复的剥离强度等,还包括飞边宽度. 五、塑料编织袋制袋流程简述●编织袋制袋工艺是塑编的最后一道工序,它包括:印刷,切割,缝合,打包等几个主要环节。

●(1)印刷图文塑编印刷主要是凸版印刷,印刷图文位置公差,印刷图文清晰度,印刷图文色彩等,在塑料产品国家标准中没有明确规定,有的标准中仅要求印刷清晰。

因而塑编企业要根据用户要求制定企业印刷标准。

制定企业标准时,要考虑自己印刷设备种类,印刷油墨种类,印刷能力等2)缝制工艺缝合强度指标是制袋的最重要,最关键指标,在塑料编织袋GB/T8946和复合塑料编织袋GB/T8947国家标准中,明确了缝边向和缝底向的拉伸负荷。

影响缝合强度的主要因素是缝合线的种类和型号,针距大小,线迹,卷边或折边缝合线到袋边的尺寸,热切和冷切方式等。

对于复膜冷切割袋,一般采用卷边处理,因为冷切边缘的缝线可能从经丝中连同纬丝撕出塑料编织袋,复合塑料编织袋,集装袋,水泥袋,所有外观质量欠缺并非都是制袋工序造成的。

但是,制袋工序是最后一道工序,也是质量把关的最后一道工序。

普通编织袋制袋工艺指标主要是外型公差尺寸,缝底向或缝边向的拉断力,印刷油墨的清晰度和印刷后其他部位的清洁度,版面位置准确度,缝合线迹,针距,及缝合脱针,断线等缺欠的要求。

五、内衬袋工艺流程简述●聚乙烯物料经挤出机加热,熔融塑化稳定挤出,通过机头挤出成圆筒型薄膜,通入压缩气吹胀,形成管泡,由冷却风环冷却定型,牵引入人字夹板折合,经牵引辊、传动辊至收卷辊,最后进行切割、热合工序完成内衬袋的生产●五、塑料回收造粒工艺流程简述●原料(废丝)被加入主机进料口,然后进入挤出机,进入挤出机后的原料在外部加热和螺杆与机筒的互相剪切下,物料被塑化熔融,再被定量、定压从模头料孔挤出,经旋转刀片切割,成为粒状颗粒进入冷却水中冷却,经振动筛筛选,粒料再经旋风水冷分离装置,进入产品区。

三、再生料的含义●编织袋中有无再生料,这个问题难以界定.从理论上来讲,编织袋的原料经挤出拉丝,再回收使用都应属再生料范围,并非指废旧编织袋回收造粒再生料.然而从实际生产情况看, 原料经挤出拉丝不可能没有●边丝和废丝的产生,就是全自动扁丝机组也要把扁丝,废丝破碎直接回收掺混再用,因而实际上不存在一点无再生料的编织袋,除非特殊用途的编织布,把边丝,废丝全部收集另用。

●一般所说的无再生料编织袋是指生产编织袋时,不另加外购废旧再生料,生产中的边丝和废丝按比例添加添加新料中再用,这就是一般所说的“全新料编织袋”。

●编织袋中有无再生料,很难用视觉判断.到目前为止,既没有国家标准,也没有行业标准规定新料中添加多少回收料为再生料编织袋.●塑编企业内部有个不成文的行话:生产编织袋过程中,新料回收造粒成为一次回料,废旧编织袋回收造粒成为二次回料。

按这个说法,添加一次回料的编织袋不属于添加再生料编织袋,●而添加二次回料的编织袋属于添加再生料编织袋,全部二次回料生产的编织袋称为再生编织袋。

●尽管塑料编织行业稳中有升,但塑料编织行业仍然是劳动密集型,低附加值的产业。

单纯制造塑料编织袋的企业仍是微利。

●而生产高附加值的塑料产品,如BOPP彩印膜袋、真空镀铝膜袋、复合袋、集装袋的企业效益比较丰厚,高附加值的塑编产品赢利空间会继续大于低档次的再生塑编产品。

(英文版)Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of comprehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen inner-party supervision of major initiatives. The two regulations supporting each other, the < code > adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard; < rule > around the party discipline, disciplinary ruler requirements, listed as "negative list, focusing on vertical gauge, draw the party organizations and Party members do not touch the" bottom line ". Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process; the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party; the third part introduces two party regulations modified the main changes and needs to grasp several key problems; the fourth part on how to grasp the implementation of the two regulations of the party. < code > and < Regulations > revised the necessity and revisedhistory of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines > and < Chinese Communist Party discipline and Punishment Regulations > column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation; follow the correct direction, grasp the limited goals, adhere to the party's leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the < code > and < rule >, reflects the party's 18 and the eighth session of the third, the spirit of the fourth plenary session, reflecting the experience of studying and implementing the General Secretary Xi Jinping series of important speech, reflects the party's eighteen years comprehensive strictly practice. (a) revised two regulations of the party need of < the ICAC guidelines > in < in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) > based on revised, the promulgation and implementation of January 2010, to strengthen the construction of the contingent of leading cadres play animportant role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too complicated, "eight prohibition, 52 are not allowed to" hard to remember, and also difficult to put into practice; the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements; the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat; the fourth is to "clean" the theme is not prominent, not for the existing problems, and is narrow, only needle of county-level leading cadres above. < rule > is in 1997 < Chinese Communist Party disciplinary cases (Trial) > based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the comprehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition; two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage theauthority of Party Constitution of misconduct lack necessary and serious responsibility to pursue; third is the main discipline for the leading cadres, does not cover all Party members. Based on the above situation, need to < the criterion of a clean and honest administration > and < rule > the two is likely to be more relevant regulations first amendment. By revising, really put the authority of Party discipline, the seriousness in the party tree and call up the majority of Party members and cadres of the party constitution of party compasses party consciousness. (II) two party regulations revision process the Central Committee of the Communist Party of China attaches great importance to two regulations revision . Xi Jinping, general books recorded in the Fifth Plenary Session of the eighth session of the Central Commission for Discipline Inspection, on the revised regulations < > made clear instructions. According to the central deployment, the Central Commission for Discipline Inspection from 2014 under six months begin study two regulations revision. The Standing Committee of the Central Commission for Discipline Inspection 4 review revised. Comrade Wang Qishan 14 times held a special meeting to study two regulations revision, amendment clarifies the direction, major issues of principle, path and target,respectively held a forum will listen to part of the province (area) secretary of the Party committee, Secretary of the Discipline Inspection Commission, part of the central ministries and state organs DepartmentThe first party committee is mainly responsible for people, views of experts and scholars and grassroots party organizations and Party members. Approved by the Central Committee of the Communist Party of China, on 7 September 2015, the general office of the Central Committee of the Party issued a notice to solicit the provinces (autonomous regions, municipalities) Party, the central ministries and commissions, state ministries and commissions of the Party (party), the General Political Department of the military, every 3 people organization of Party of two regulations revision opinion. Central Commission for Discipline Inspection of extensive solicitation of opinions, careful study, attracting, formed a revised sent reviewers. In October 8 and October 12, Central Committee Political Bureau Standing Committee and the Political Bureau of the Central Committee After consideration of the two regulations revised draft. On October 18, the Central Committee of the Communist Party of China formally issued two regulations. Can say, two laws amendment concentrated thewisdom of the whole party, embodies the party. Second, < code > and < Regulations > revision of the basic principles of two party regulations revision work and implement the party's eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised < low political criterion > and < Regulations >, highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a long-term, advance as a whole, with Bu Xiuding independent < rule > and < rule >. Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and self-discipline required specific, awaken the party constitution of party compasses party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that "no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules.
