iimveliso

Ibakala lefilimu ye-LDPE 202TN00,
polyethylene yoxinzelelo oluphezulu, ldpe kwimveliso yefilimu, I-Polyethylene yoxinano oluphantsi,

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

Isicelo

I-LDPE(2102TN000) yimathiriyeli yefilimu ye-extrusion enhle kakhulu, ilungele ukuveliswa kwefilimu yokupakisha enzima, ifilimu echithweyo, ifilimu yokupakisha eshwabeneyo, njalo njalo.Usetyenziso lomda we-polyethylene yoxinaniso oluphantsi: ilungele isinongo, iikeyiki, iswekile, iziqhamo ezifakwe kwi-candied. , iibhiskithi, umgubo wobisi, iti, i-fish floss kunye nezinye iipakethe zokutya.Ukupakishwa kweepilisi, umgubo kunye namanye amachiza, ukupakishwa kweehempe, iimpahla, iimveliso zomqhaphu ezinithiweyo kunye neemveliso zefiber zekhemikhali kunye nezinye iimveliso zefiber.Umgubo wokuhlamba, isepha, izinto zokuthambisa kunye nezinye iimveliso zemichiza yemihla ngemihla yokupakishwa.Ngenxa yeempawu ezimbi zomatshini wefilimu ye-PE ene-single-layer, idla ngokusetyenziswa njengomaleko wangaphakathi weengxowa zokupakisha ezihlanganisiweyo, oko kukuthi, i-substrate yokutywinwa kobushushu yefilimu ehlanganisiweyo ye-multi-layer.

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.
