Uxinaniso oluphantsi Polyethylene 2102TN00
I-polyethylene yoxinano oluphantsi (LDPE) yiresin eyenziweyo esebenzisa inkqubo yoxinzelelo oluphezulu nge-polymerization yasimahla ye-ethylene kwaye ke ikwabizwa ngokuba "yi-polyethylene yoxinzelelo oluphezulu".Uxinzelelo oluphantsi lwe-polyethylene engenavumba, engenancasa, amasuntswana amhlophe angenatyhefu okanye umgubo.Indawo yokunyibilika yi-131 ℃.Uxinzelelo 0.910-0.925 g/cm³.Indawo yokuthambisa 120-125℃.iqondo lobushushu embrittlement -70℃.Elona qondo lobushushu liphezulu lokusebenza 100℃.Ngokumelana nokushisa okukhulu, ukumelana nokubanda, ukumelana nokugqoka kunye neempawu ze-dielectric, ukuzinza kweekhemikhali.Phantse i-insoluble kuyo nayiphi na i-solvent ye-organic kwiqondo lokushisa.Inokumelana nokubola kweasidi ezahlukeneyo kunye nealkali kunye nezisombululo ezahlukeneyo zetyuwa.I-polyethylene yoxinzelelo oluphantsi isetyenziswa ngokubanzi kumashishini amayeza kunye neekhemikhali ukwenza iimveliso ezingenanto, ezifana nemibhobho, iibhotile kunye neetanki zokugcina.Ishishini lokutya lilisebenzisa ukwenza imigqomo yokupakisha.Ishishini lomatshini lisetyenziselwa ukwenza amaqweqwe, izibambo, amavili ezandla kunye namanye amalungu omatshini ngokubanzi, kwaye ishishini lamaphepha lisetyenziselwa ukwenza iphepha lokwenziwa.
Uphawu
I-LDPE inomsebenzi omhle wokubumba kunye nefilimu eyenza iipropati ezintle ze-optical, iimpawu zomatshini kunye neempawu zokutywinwa kobushushu, ukumelana nokubanda, ukushisa okuphantsi kunye nokumelana nokushisa okuphezulu.Ifilim eshinyeneyo inokumelana nenkqubo yokuvala inzala yokuntywila kwi-90℃ yamanzi ashushu.Isetyenziswa kakhulu kwishishini lokupakisha.
Isicelo
I-LDPE(2102TN000) yimathiriyeli yefilimu ye-extrusion elungileyo kakhulu, ilungele ukuveliswa kwefilimu yokupakisha enzima, ifilimu echithiweyo, ifilimu yokupakisha eshwabeneyo yobushushu njalo njalo.

Ukupakishwa, uGcino kunye noThutho
I-resin ifakwe kwiingxowa ze-polypropylene ezifakwe ngaphakathi kwifilimu.Ubunzima obushiyekileyo bungama-25Kg/ibhegi.I-resin kufuneka igcinwe kwindawo yokugcina impahla, eyomileyo kwaye kude nomlilo kunye nelanga elithe ngqo.Akufunekanga ifunjwe kwindawo evulekileyo.Ngexesha lokuthuthwa, imveliso akufanele ibekwe kwilanga elinamandla okanye imvula kwaye akufanele ihanjiswe kunye nesanti, umhlaba, isinyithi esilahliweyo, amalahle okanye iglasi.Uthutho kunye nezinto eziyityhefu, ezidlekayo nezinokutsha akuvumelekanga ngokungqongqo.
