Ukuminyana okuphansi Ifilimu yePolyethylene Ibanga 2100TN00
I-Low density polyethylene (LDPE), eyaziwa nangokuthi i-polyethylene yomfutho ophezulu, iyinhlaka emhlophe ene-waxy texture, futhi isakhiwo sayo samangqamuzana isakhiwo esingenantambo esinenani elikhulu lamaketanga amagatsha amade.Uma kuqhathaniswa nokuminyana okuphakathi, i-polyethylene ephakeme kakhulu, i-crystallinity ye-LDPE, indawo yokuthambisa iphansi, ukuthamba, ukunwetshwa, ukwahlukanisa kagesi nokucaca kungcono, amandla omthelela aphezulu, ifaneleka ukucubungula kwe-thermoplastic kwenqubo yokwakheka ehlukahlukene, ukucutshungulwa kokwakheka kuhle.LDPE isetshenziselwa ikakhulukazi imikhiqizo yefilimu, kodwa futhi nemikhiqizo yokubumba umjovo, amathuluzi ezokwelapha, izidakamizwa nezinto zokupakisha zokudla, imikhiqizo yokubumba engenalutho, kwezolimo, embonini yokupakisha, ubunjiniyela be-elekthronikhi nogesi, okokusebenza kwemishini, ukukhiqizwa kwezimoto kanye nokudla kwansuku zonke nokunye. izici zinebanga elibanzi lamathemba okusebenza.
Isici
I-LDPE ine-crystallinity ephansi, iphuzu lokuthambisa, ukuthamba okuhle, ukunwebeka, ukwahlukanisa kagesi nokungafihli, amandla omthelela aphezulu, ngakho-ke ifaneleka kakhulu ekucubunguleni ukwakheka kwe-thermoplastic kwezinqubo ezahlukahlukene zokwakha, imikhiqizo inokucutshungulwa okuhle kokubumba.
Isicelo
I-LDPE(2100TN00) iyifilimu enhle ye-extrusion, elungele ukukhiqizwa kwefilimu yokupakisha elula, ifilimu ye-mulch yezolimo, impahla yeshidi legwebu.

Iphakheji, Isitoreji kanye Nezokuthutha
I-resin ifakwe ezikhwameni ezilukiwe ze-polypropylene ezifakwe ngaphakathi ngefilimu.Isisindo esiphelele singama-25Kg/isikhwama.I-resin kufanele igcinwe endaweni yokugcina impahla, eyomile futhi kude nomlilo kanye nelanga eliqondile.Akufanele inqwabelane endaweni evulekile.Ngesikhathi sokuthutha, umkhiqizo akufanele ubekwe elangeni elinamandla noma imvula futhi akufanele uhanjiswe kanye nesihlabathi, inhlabathi, izinsimbi ezilahliwe, amalahle noma ingilazi.Ukuhamba nezinto ezinobuthi, ezonakalisayo nezivuthayo akuvunyelwe ngokuphelele.
