imikhiqizo

Ibanga lefilimu le-LDPE 202TN00,
i-polyethylene ephezulu, ldpe ukukhiqizwa kwefilimu, I-Low Density Polyethylene,

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

Isicelo

I-LDPE(2102TN000) iyifilimu enhle kakhulu ye-extrusion, elungele ukukhiqizwa kwefilimu enzima yokupakisha, ifilimu elichithiwe, ifilimu yokupakisha encibilikayo nokunye.Ububanzi bokufaka isicelo se-polyethylene esezingeni eliphansi: ilungele isinongo, amakhekhe, ushukela, isithelo sikaswidi. , amabhisikidi, ubisi oluyimpushana, itiye, i-fish floss nokunye okupakisha ukudla.Ukupakishwa kwamaphilisi, izimpushana nezinye izidakamizwa, ukupakisha amahembe, izingubo zokugqoka, imikhiqizo kakotini onikiwe kanye nemikhiqizo yefiber yamakhemikhali neminye imikhiqizo yefiber.Impushana yokuwasha, okokuhlanza, izimonyo kanye neminye imikhiqizo yansuku zonke yemikhiqizo yamakhemikhali.Ngenxa yezakhiwo ezimbi zemishini yefilimu ye-PE yongqimba olulodwa, ivame ukusetshenziswa njengesendlalelo sangaphakathi sezikhwama zokupakisha eziyinhlanganisela, okungukuthi, i-substrate evala ukushisa yefilimu enezingqimba eziningi.

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.
