(7) I-PE (i-polyethylene)
1. Ukusebenza kwe-PE
I-PE iyipulasitiki enomkhiqizo omkhulu phakathi kwamapulasitiki.Ibonakala ngekhwalithi ethambile, ukungabi nobuthi, intengo ephansi, ukucubungula okulula, ukumelana okuhle kwamakhemikhali, akulula ukugqwala, futhi kunzima ukuyiphrinta.I-PE iyi-polymer ejwayelekile ye-crystalline.
Inezinhlobo eziningi, ezivame ukusetshenziswa yi-LDPE (i-polyethylene ephansi) kanye ne-HDPE (i-polyethylene ephakeme kakhulu), okungamapulasitiki ashintshashintshayo anamandla aphansi kanye namandla athile adonsela phansi angu-0.94g/cm3 (amancane kunamanzi);ama-resin e-LLDPE aphansi kakhulu (Ukuminyana kungaphansi kuka-0.910g/cc, futhi ukuminyana kwe-LLDPE ne-LDPE kuphakathi kuka-0.91-0.925).
I-LDPE ithambile, (ejwayele ukubizwa ngokuthi irabha ethambile) I-HDPE yaziwa kakhulu ngokuthi irabha eqinile ethambile.Iqinile kune-LDPE futhi iyingxenye ye-semi-crystalline.Ukuqhekeka kokucindezeleka kwemvelo kwenzeka.Ukucindezeleka kwangaphakathi kungancishiswa ngokusebenzisa izinto ezinezici zokugeleza eziphansi kakhulu, ngaleyo ndlela kuncishiswe ukwenzeka kokuqhekeka.Kulula ukuncibilika kuzincibilikisi ze-hydrocarbon lapho izinga lokushisa lingaphezu kuka-60 °C, kodwa ukumelana kwayo nokuhlakazeka kungcono kunokwe-LDPE.
I-crystallinity ephezulu ye-HDPE ibangela ukuminyana kwayo okuphezulu, amandla aqinile, izinga lokushisa eliphezulu lokuhlanekezela izinga lokushisa, i-viscosity kanye nokuzinza kwamakhemikhali.Ukumelana nokungena okunamandla kune-LDPE.I-PE-HD inamandla omthelela aphansi.Izakhiwo zilawulwa ikakhulukazi ukuminyana nokusatshalaliswa kwesisindo samangqamuzana.
I-HDPE elungele ukubunjwa komjovo inokusabalalisa kwesisindo samangqamuzana amancane.Ngobuningi be-0.91 ~ 0.925g/cm3, sikubiza ngokuthi uhlobo lokuqala lwe-PE-HD;ngobuningi be-0.926 ~ 0.94g/cm3, kubizwa ngokuthi uhlobo lwesibili lwe-HDPE;ngokuminyana okungu-0.94~0.965g/cm3, kubizwa ngokuthi uhlobo lwesibili lwe-HDPE Iwuhlobo lwesithathu lwe-HDPE.
Izici zokugeleza zalolu lwazi zinhle kakhulu, zine-MFR ephakathi kuka-0.1 no-28. Uma uphakeme isisindo samangqamuzana, izici zokugeleza ze-LDPE ziba mpofu, kodwa amandla omthelela angcono.I-HDPE ithambekele ekuqhekekeni kokucindezeleka kwemvelo.Ukuqhekeka kungancishiswa ngokusebenzisa izinto ezinezindawo zokugeleza eziphansi kakhulu ukuze kuncishiswe ukucindezeleka kwangaphakathi.I-HDPE incibilika kalula kuzincibilikisi ze-hydrocarbon lapho izinga lokushisa lingaphezu kuka-60C, kodwa ukumelana kwayo nokuhlakazeka kungcono kunokwe-LDPE.
I-LDPE iyi-semi-crystalline material ene-shrinkage ephezulu ngemva kokubunjwa, phakathi kuka-1.5% no-4%.
I-LLDPE (I-Linear Low Density Polyethylene) inezinto eziqinile eziphakeme, ukungena, umthelela kanye nezinyembezi ezenza i-LLDPE ifanele amafilimu.Ukumelana kwayo okuhle kakhulu nokuqhekeka kokucindezeleka kwemvelo, ukumelana nomthelela wokushisa okuphansi kanye nokumelana ne-warpage kwenza i-LLDPE ikhange ipayipi, i-extrusion yeshidi kanye nazo zonke izinhlelo zokusebenza zokubumba.Ukusetshenziswa kwakamuva kwe-LLDPE kufana nemboza yezindawo zokulahla imfucumfucu kanye nezindonga zamachibi emfucuza.
2. Izici zenqubo ye-PE
Isici esiphawuleka kakhulu sezingxenye ze-PE ukuthi izinga lokuncibilika lokubumba likhulu, elijwayele ukuncipha nokuguqulwa.Impahla ye-PE inokumuncwa okuphansi kwamanzi, ngakho-ke ayidingi ukomiswa.I-PE inebanga lokushisa elibanzi lokucubungula futhi akulula ukubola (izinga lokushisa lokubola lingu-320°C).Uma ingcindezi inkulu, ukuminyana kwengxenye kuzoba phezulu futhi izinga lokuncipha lizoba lincane.
I-fluidity ye-PE iphakathi, izimo zokucubungula kufanele zilawulwe ngokuqinile, futhi izinga lokushisa lesikhunta kufanele ligcinwe lingashintshi (40-60 ℃).Izinga le-crystallization ye-PE lihlobene nezimo zenqubo yokubumba.Inezinga lokushisa eliphakeme lokuqandisa kanye nezinga lokushisa eliphansi lesikhunta, futhi icrystallinity iphansi.Phakathi nenqubo ye-crystallization, ngenxa ye-anisotropy ye-shrinkage, ukucindezeleka kwangaphakathi kugxilile, futhi izingxenye ze-PE zijwayele ukuguqulwa nokuqhekeka.
Umkhiqizo ufakwa emanzini okugeza emanzini ashisayo ku-80 ° C, okungakhulula ukucindezela ngezinga elithile.Ngesikhathi senqubo yokubumba, izinga lokushisa lempahla kanye nokushisa kwesikhunta kufanele kube ngaphezulu, futhi ingcindezi yomjovo kufanele ibe ngaphansi ngaphansi kwesisekelo sokuqinisekisa ikhwalithi yezingxenye.Ukupholisa kwesikhunta kuyadingeka ikakhulukazi ukuba kusheshe futhi kufane, futhi umkhiqizo uzoshisa lapho udilizwa.
Ukomiswa kwe-HDPE: ukomisa akudingekile uma kugcinwe kahle.Izinga lokushisa elincibilikayo 220 ~ 260C.Ngezinto zokwakha ezinama-molecule amakhulu, izinga lokushisa elinconyiwe lokuncibilika liphakathi kuka-200 no-250C.
Izinga lokushisa lesikhunta: 50~95C.Izingxenye zepulasitiki ezinokuqina kodonga ngaphansi kuka-6mm kufanele zisebenzise izinga lokushisa eliphakeme lesikhunta, futhi izingxenye zepulasitiki ezinobukhulu obungaphezu kuka-6mm kufanele zisebenzise izinga lokushisa eliphansi lesikhunta.Izinga lokushisa lokupholisa lengxenye yepulasitiki kufanele lifane ukuze kuncishiswe umehluko ekuncipheni.Ukuze uthole isikhathi esifanelekile somjikelezo womshini, ububanzi besiteshi sokupholisa akufanele bube ngaphansi kuka-8mm futhi ibanga ukusuka endaweni yokubumba kufanele libe phakathi kuka-1.3d (lapho u-“d” kuwububanzi beshaneli yokupholisa).
Ingcindezi yomjovo: 700 ~ 1050bar.Isivinini Somjovo: Umjovo wesivinini esiphezulu uyanconywa.Abagijimi namasango: Ububanzi bomgijimi buphakathi kuka-4 no-7.5mm, futhi ubude bomgijimi kufanele bube bufushane ngangokunokwenzeka.Izinhlobo ezihlukahlukene zamasango zingasetshenziswa, futhi ubude besango akufanele budlule u-0.75mm.Ikakhulukazi efanelekile ukusetshenziswa kwesikhunta somgijimi oshisayo.
Isakhiwo se-LLDPE "sokunwebeka" se-LLDPE siwukungalungi enqubweni yefilimu evuthelwe umoya, futhi ibhamuza lefilimu elivutheziwe le-LLDPE alizinzile njengalelo le-LDPE.Igebe lokufa kufanele linwetshwe ukuze kugwenywe ukuncipha kokuphuma ngenxa yomfutho ophakeme womgogodla kanye nokuqhekeka kokuncibilika.Ubukhulu begebe lokufa elijwayelekile le-LDPE ne-LLDPE lingu-0.024-0.040 in no-0.060-0.10 in, ngokulandelanayo.
3. Ibanga lohlelo lokusebenza elijwayelekile:
I-LLDPE ingene ezimakethe eziningi zendabuko ze-polyethylene, okuhlanganisa ifilimu, ukubumba, ipayipi, nocingo nekhebuli.I-Anti-Leakage mulch iyimakethe esanda kuthuthukiswa ye-LLDPE.I-mulch, ishidi elikhulu elikhishiwe elisetshenziswa njengendawo yokulahla imfucumfucu kanye nemigqa yamachibi kadoti ukuze kuvinjelwe ukugeleza noma ukungcoliswa kwezindawo ezizungezile.
Izibonelo zifaka ukukhiqizwa kwezikhwama, izikhwama zikadoti, ukupakishwa okunwebekayo, omalayini bezimboni, amalayini ethawula nezikhwama zokuthenga, konke okusebenzisa ngokunenzuzo amandla athuthukisiwe kanye nokuqina kwale resin.Amafilimu acacile, njengezikhwama zesinkwa, abuswe yi-LDPE ngenxa yobungunga bayo obungcono.
Kodwa-ke, izingxube ze-LLDPE ne-LDPE zizothuthukisa amandla.Ukumelana nokungena kanye nokuqina kwamafilimu e-LDPE ngaphandle kokuthikameze kakhulu ukucaca kwefilimu.
Ibanga lesicelo se-HDPE: iziqukathi zesiqandisi, iziqukathi zokugcina, izinto zasekhishini zasendlini, izembozo zokuvala, njll.
