Iinkcukacha zeMveliso

Iithegi zeMveliso

Uxinzelelo oluphantsi lwe-polyethylene,
I-polyethylene ephantsi yoxinaniso esetyenziselwa ifilimu,

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 elungileyo kakhulu, ilungele ukuveliswa kwefilimu yokupakisha enzima, ifilimu echithiweyo, ifilimu yokupakisha eshwabeneyo yobushushu njalo njalo.

Iiparamitha

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.

I-LDPE Film Grade 2102TN00 (3)
I-polyethylene ephantsi yoxinaniso, okanye i-LDPE, ibonakaliswe ngamatyathanga amasebe amaninzi kunye ne-random, i-branching ende.I-LDPE inoxinano ukusuka kwi-.910 ukuya kwi-.935 grams nge-cubic centimeter (g/cc).

Xa kuziwa ekusetyenzisweni kwayo kwiifilimu zeplastiki, iintlaka ze-LDPE zibonelela ngokuqina okwamkelekileyo, ukuguquguquka, ukubona, kunye nokungena.Ngelixa ingenamandla njengeresin ze-LLDPE, i-LDPE ibonelela ngeempawu ezintle zokushwabana.
