Ukuminyana okuphansi I-Polyethylene 2102TN00
I-polyethylene ene-low-density (LDPE) iyinhlaka yokwenziwa esebenzisa inqubo yokucindezela okuphezulu nge-polymerization yamahhala ye-ethylene futhi ngenxa yalokho ibizwa nangokuthi "i-polyethylene ephezulu yokucindezela".I-polyethylene enengcindezi ephansi engenaphunga, ayinambitheki, izinhlayiya ezimhlophe ezingenabuthi noma impushana.Iphuzu elincibilikayo lingu-131 ℃.Ukuminyana 0.910-0.925 g/cm³.Iphoyinti lokuthambisa 120-125 ℃.Ukushisa kwe-embrittlement -70 ℃.Izinga lokushisa eliphezulu lokusebenza ngu-100 ℃.Ngokumelana nokushisa okuhle kakhulu, ukumelana nokubanda, ukumelana nokugqoka kanye nezakhiwo ze-dielectric, ukuzinza kwamakhemikhali.Cishe ayincibiliki kunoma iyiphi i-solvent ye-organic ekamelweni lokushisa.Ingakwazi ukumelana nokugqwala kwe-asidi ehlukahlukene kanye ne-alkali nezixazululo ezihlukahlukene zikasawoti.I-polyethylene enengcindezi ephansi isetshenziswa kakhulu ezimbonini zemithi namakhemikhali ukwenza imikhiqizo engenalutho, njengemiphongolo, amabhodlela kanye namathangi okugcina.Imboni yokudla ikusebenzisa ukwenza iziqukathi zokupakisha.Imboni yemishini isetshenziselwa ukwenza amakhava, izibambo, amasondo ezandla nezinye izingxenye zemishini evamile, futhi imboni yephepha isetshenziselwa ukwenza iphepha lokwenziwa.
Isici
I-LDPE inokusebenza okuhle kokubumba kanye nefilimu eyenza izinto ezinhle ze-optical, izakhiwo zemishini kanye nezakhiwo zokuvala ukushisa, ukumelana nokubanda, izinga lokushisa eliphansi kanye nokumelana nokushisa okuphezulu.Ifilimu ewugqinsi ingamelana nenqubo yokuvala inzalo yokucwiliswa emanzini ashisayo angu-90℃.Isetshenziswa kabanzi embonini yokupakisha.
Isicelo
I-LDPE(2102TN000) iyinto enhle kakhulu yefilimu ye-extrusion, efaneleka kakhulu ukukhiqizwa kwefilimu yokupakisha esindayo, ifilimu elichithiwe, ifilimu yokupakisha enciphayo nokushisa nokunye.

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.
