I-LDPE, noma i-low-density polyethylene, ipulasitiki edumile esetshenziswa emikhiqizweni eyahlukene, okuhlanganisa nokupakisha.I-LDPE yaziwa ngokuguquguquka kwayo, amandla, nokucaca, okuyenza ibe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza eziningi ezahlukene.Enye yezindlela ezivame kakhulu ze-LDPE ifilimu ye-LDPE yokunciphisa ukushisa, esetshenziswa kakhulu embonini yokupakisha.Uma ungathanda ukufunda kabanzi mayelana nendlela i-LDPE ekhiqizwa ngayo kanye nendima yabakhiqizi bamafilimu be-LDPE kule nqubo, qhubeka ufunda.
Inqubo yokukhiqiza ye-LDPE iqala ngokukhipha i-ethylene (igesi le-hydrocarbon) kugesi yemvelo noma i-naphtha.Ngemva kokutholakala kwe-ethylene, ingena kwinqubo ebizwa ngokuthi i-polymerization, ehlanganisa ukuhlanganisa ama-molecule e-ethylene ndawonye ukuze akhe amaketanga amade e-LDPE.Inqubo ye-polymerization ingenziwa ngezindlela ezahlukene, okuhlanganisa i-polymerization ephezulu yokucindezela noma i-polymerization yamahhala, evame ukusetshenziselwa ukukhiqiza i-LDPE.
Ngemuva kwenqubo ye-polymerization, i-LDPE ibe isincibilika futhi yakheke ibe yisimo esifisayo, njengefilimu, ngenqubo ebizwa ngokuthi i-extrusion.Ifilimu yokunciphisa ukushisa kwe-LDPE, ikakhulukazi, ikhiqizwa kusetshenziswa uhlobo olukhethekile lwe-extrusion olubizwa nge-blow film extrusion.Kule nqubo, i-LDPE iyancibilika futhi iphoqelelwe ngefa eliyindilinga, elidala ithubhu lepulasitiki elincibilikisiwe.Ishubhu libe selivuthelwa umoya, noma "lishaywe umoya," ngomoya ukuze lilule futhi lilolonge libe ukujiya nobubanzi obufunekayo.Ifilimu ibe isipholiswa bese igaywa emigqeni emikhulu ukuze kuqhutshekwe nokucubungula nokusatshalaliswa.
Uma ifilimu ye-LDPE isikhiqiziwe, ivamise ukuthengiselwa abakhiqizi bamafilimu be-LDPE, abangaqhubeka bacubungule okokusebenza futhi bakuguqule kube izinhlobo ezahlukahlukene zemikhiqizo yokupakisha, okuhlanganisa ifilimu yokunciphisa ukushisa.Abakhiqizi bamafilimu be-LDPEidlala indima ebalulekile enqubweni yokukhiqiza ngokuhlinzeka ngezinsizakalo ezingeziwe, njengokuphrinta, ukulayeza, nokuguqula ifilimu ye-LDPE ibe imikhiqizo eqediwe ehlangabezana nezidingo ezithile zamakhasimende abo.
Ngaphezu kokukhiqizwa nokucubungula kwefilimu ye-LDPE,Abakhiqizi bamafilimu be-LDPEfuthi banesibopho sokuqinisekisa ikhwalithi nokuvumelana kwezinto.Lokhu kuhilela ukuhlolwa okuphelele kanye nezinyathelo zokulawula ikhwalithi ukuze kuqinisekiswe ukuthi ifilimu ye-LDPE ihlangabezana nezicaciso ezidingekayo kanye namazinga okusetshenziswa okuhlosiwe.Abakhiqizi bamafilimu be-LDPE bangase futhi basebenze eduze namakhasimende abo ukuze banikeze ulwazi lobuchwepheshe nokusekelwa, ukubasiza ukukhetha uhlobo olulungile lwefilimu ye-LDPE ngezidingo zabo zokupakisha.
Sengiphetha, i-LDPE iyimpahla yepulasitiki eguquguqukayo futhi esetshenziswa kabanzi ekhiqizwa ngenqubo ye-polymerization kanye ne-extrusion.Abakhiqizi bamafilimu be-LDPE badlala indima ebalulekile ekukhiqizweni nasekucutshungulweni kwefilimu ye-LDPE, okuhlanganisa nokukhiqizwa kwefilimuIfilimu yokunciphisa ukushisa kwe-LDPE.Ngokuhlinzeka ngamasevisi anenani elingeziwe kanye nokuqinisekisa ikhwalithi yezinto ezibonakalayo, abakhiqizi bamafilimu be-LDPE bafaka isandla ekukhiqizweni okuphumelelayo nokusezingeni eliphezulu kwemikhiqizo yokupakisha ye-LDPE.Uma udinga ifilimu ye-LDPE ngezidingo zakho zokupakisha, qiniseka ukuthi ubambisana nomkhiqizi wefilimu ohlonishwayo we-LDPE ongahlangabezana nezidingo zakho ezithile.
