Inhlanganisela yayo yokuthamba, ukuqina, nokucaca kombono kuyenza ibe yisinqumo esizenzakalelayo sokupakisha okuguquguqukayo, ukukhiqizwa kwefilimu, nezingxenye eziningi zezimboni. Abathengi abafuna umlingani wokuhlinzeka nge-LDPE othembekile bathola ngokushesha ukuthi ukungaguquguquki kwezinga kubalulekile njengoba nje intengo eyinhloko ibalulekile. I-Mier Plastic Material Co., Ltd yakha isithunzi sayo ngokungaguquguquki lokho, ihlanganisa iminyaka yolwazi lokuhlanganisa nokulawulwa okuqinile kweqoqo. Lo mhlahlandlela uchaza ukuthi iyini i-LDPE, isebenza kanjani, nokuthi ungayithola kanjani ngobuhlakani emgqeni wakho wokukhiqiza.

Noma ngabe ucindezela ifilimu evuthelwe yezikhwama zasezitolo noma ubumba amabhodlela akhanywayo omkhiqizo wezimonyo, i-polymer oyikhethayo inquma umkhiqizo, izinga lokuphrinta, kanye nokwaneliseka komsebenzisi wokugcina. I-LDPE ihlezi isenhliziyweni yaleso sinqumo ngoba ilinganisela ukulula kokucubungula nokusebenza okuthembekile kwemishini. Kulo lonke leli phepha sihlola ukuminyana, inkomba yokuncibilika, izengezo zezithako, kanye nokugaywa kabusha ngendlela esebenzayo hhayi ngethiyori engaqondakali. Siphinde siqhathanise i-LDPE ne-linear low density polyethylene kanye ne-high density polyethylene ukuze ukwazi ukukhetha i-resin efanele ngokushesha. Ngaphezu kwalokho, sichaza ukuthiMayelana Nathiisekela abaguquli, abanikazi bemikhiqizo, kanye nozakwethu bezohwebo ngamasampula, izilinganiso, kanye nesiqondiso sobuchwepheshe.

Yini i-LDPE? Incazelo, Inqubo Yokukhiqiza, kanye Nezici Ezibalulekile

I-LDPE iyi-thermoplastic eyenziwe ngokuhlanganisa i-ethylene gas ngaphansi kwengcindezi ephezulu kakhulu, ngokuvamile phakathi kuka-1,500 no-3,000 bar, emazingeni okushisa angu-150 kuya ku-300 degrees Celsius kusetshenziswa ama-free-radical initiators. Ngenxa yokuthi ukusabela akukho-catalyzed ngendlela elawulwayo efanayo nama-linear polyolefins, amaketanga akhiqizayo athwala amagatsha amade namafushane eduze komgogodla. Lawo magatsha avimbela ama-molecule ukuthi ahlangane ngokuqinile, yingakho i-resin eqediwe inokuminyana okucishe kube ngu-0.910 kuya ku-0.940 g/cm3 kanye ne-crystallinity engu-40 kuya ku-55 percent kuphela. Isakhiwo esinamagatsha futhi sehlisa izinga lokuncibilika lifinyelele cishe ku-105 kuya ku-115 degrees Celsius, okuyisici abakhiqizi abasisebenzisayo ekushiseleni ngokuncibilika. Uma kuqhathaniswa nama-polyethylene anokuminyana okuphezulu, i-LDPE izwakala inamafutha, inwebeka, futhi ikhanya kancane ezingxenyeni ezincane. Lezi zici eziyisisekelo zichaza ukuthi kungani le nto isalokhu ibusa kwezohwebo kusukela ngawo-1930.

Ngokombono osebenzayo, izici ezimbalwa zichaza indlela i-LDPE eziphatha ngayo endaweni yokusebenza. Igeleza kalula kuma-extruder ngoba i-viscosity yayo encibilikayo iphansi uma iqhathaniswa, okuhumusha ekutheni kube namathuba abanzi okucubungula kanye nenani elincane lokulahlekelwa. Imelana namanzi, iningi lama-asidi, ama-base, amasawoti, kanye notshwala, nakuba ikhukhumala lapho ihlangana nama-hydrocarbon kanye nama-chlorinated solvents. Isivikelo sayo somswakama sihle kakhulu kuyilapho isivikelo sayo se-oxygen silingene nje, ngakho-ke ivamise ukuhlanganiswa namanye ama-polymer ezakhiweni ezinamazinga amaningi okupakisha ukudla. I-LDPE futhi inekhodi yokuhlonza i-resin inombolo yesine, yingakho yaziwa kabanzi ngokuthi i-ldpe 4 plastic ezinhlelweni zokugaywa kabusha kanye nemihlahlandlela yokuhlunga kamasipala. Ukubona lezi zici kusenesikhathi kuphrojekthi kusiza onjiniyela ukuthi bagweme ukuguqulwa kabusha okubizayo kamuva.

Izici Nezinzuzo ze-LDPE: Ukuminyana, Ukuguquguquka, Ukuqina, Ukumelana Namakhemikhali, Ukucaca, kanye Nokugaywa Kabusha

Izinga lokuminyana kwe-LDPE, ngokuvamile elingu-0.910 kuya ku-0.940 g/cm3, lihlala ngaphansi kwalelo le-HDPE kanye nezinhlanganisela eziningi ezigcwalisiwe, okunikeza abakhiqizi izingxenye eziningi noma indawo yefilimu eningi ngekhilogramu ngalinye le-resin. Ukuminyana okuphansi kuhumusha ngqo ekuguquguqukeni, ngakho ifilimu ye-LDPE iwela ngobumnene, isongeka ngaphandle kokuqhekeka, futhi izwakala kahle esandleni. Ukuqina kungenye inzuzo enkulu: ukuhlanganiswa kwamagatsha amade kumunca amandla okushaya futhi kumelana nokudabuka, ngisho nasemazingeni okushisa aphansi lapho amanye ama-resin ahlukile eba buthaka. Ukumelana namakhemikhali kubanzi ezintweni ze-polar, okwenza izitsha ze-LDPE zifanele izihlanzi, izinto zokuhlanza, kanye nezinhlanganisela eziningi ezinamanzi. Ukucaca kokubona ezilinganisweni ezincane kukuhle ngokwanele kuma-over-wrap namasaka esinkwa, kanti indawo yayo yamukela ukunyathelisa, ukufaka amaleya, kanye nokwelashwa nge-corona kalula.
