Boima bo tlase ba Polyethylene Film Grade QLT04 QLF39
Polyethylene e tlase-tlase (LDPE) ke resin ea maiketsetso e sebelisang ts'ebetso ea khatello e phahameng ka polymerization ea mahala ea ethylene 'me ka hona e boetse e bitsoa "polyethylene e phahameng".Kaha ketane ea eona ea limolek'hule e na le makala a mangata a malelele le a makhutšoane, LDPE ha e na kristale e nyane ho feta polyethylene e phahameng haholo (HDPE) mme boima ba eona bo tlase.E na le khanya, e tenyetsehang, e hanyetsanang le serame hantle le ho hanyetsa tšusumetso.LDPE e tsitsitse ka lik'hemik'hale.E na le khanyetso e ntle ea li-acids (ntle le li-acid tse matla tsa oxidizing), alkali, letsoai, thepa e babatsehang ea ho pata motlakase.Sekhahla sa eona sa ho kenella ha mouoane se tlase.LDPE e na le metsi a mangata 'me e sebetsa hantle.E loketse ho sebelisoa mefuteng eohle ea ts'ebetso ea thermoplastic, joalo ka ho bopa ka ente, ho bopa ha extrusion, ho bopa ha blow, rotomolding, coating, foaming, thermoforming, hot-jet welding le welding ea mocheso.
Kopo
Sehlopha sa lifilimi sa LDPE se sebelisoa haholo tlhahisong ea filimi ea ho paka ka blowmolding, filimi ea temo mme e ka kopanngoa le linear low-density polyethylene (LLDPE) ho hlahisa PE e fetotsoeng.Ho phaella moo, e ka sebelisoa bakeng sa filimi ea ho kenya mocheso, filimi e entsoeng ka laminated, filimi e batang, liphutheloana tsa bongaka, filimi ea li-multi-layer coextrusion, filimi ea ho paka e boima, liphaephe, sheathing ea cable, lesela le lik'hemik'hale tse phahameng tsa lik'hemik'hale.
LDPE (QLT04/QLF39) ke thepa e tala e ntle haholo e pepeneneng ea ho paka.
