Resin e tlase ea polyethylene
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
LDPE e sebelisoa haholo ho etsa lifilimi.E sebelisoa haholo ha ho etsoa filimi ea temo (filimi ea mulching le filimi e tšolotsoeng), filimi ea ho paka (e sebelisoang ho paka lipompong, meroho le lijo tse hatselitsoeng), filimi e bululetsoeng bakeng sa ho paka mokelikeli (ho sebelisoa ho paka lebese, soy sauce, lero, lebese la linaoa le lebese la soya), mekotla ea liphutheloana tse boima, filimi e nyenyefatsang ea ho paka, filimi ea elastic, filimi ea lining, filimi ea ho haha, filimi ea ho paka ka kakaretso ea indasteri le mekotla ea lijo.
LDPE e boetse e sebelisoa haholo tlhahisong ea terata & cable insulation sheath.Cross-linked LDPE ke thepa e ka sehloohong e sebelisoang ka har'a lera la ho kenya letsoho la likhoele tse nang le matla a phahameng.
LDPE e boetse e sebelisoa ha ho etsoa lihlahisoa tse entsoeng ka ente (tse kang lipalesa tsa maiketsetso, lisebelisoa tsa bongaka, meriana le thepa ea ho paka lijo) le li-tubes tse entsoeng ka extrusion, lipoleiti, likhoele tsa terata le lithapo le lihlahisoa tsa polasetiki tse profil.
LDPE e boetse e sebelisetsoa ho etsa lihlahisoa tse se nang letho tse kang lijana tsa lijo, meriana, litlolo le lihlahisoa tsa lik'hemik'hale, le litanka.
Sephutheloana, Polokelo le Lipalangoang
Resin e kenngoa ka har'a mekotla e lohiloeng ka filimi e entsoeng ka polypropylene.Boima ba nete ke 25Kg / mokotla.Resin e lokela ho bolokoa sebakeng sa polokelo se omeletseng, se omeletseng le hole le mollo le khanya ea letsatsi.Ha ea lokela ho bokelloa sebakeng se bulehileng.Nakong ea lipalangoang, sehlahisoa ha sea lokela ho pepesoa ke letsatsi le matla kapa pula 'me ha sea lokela ho tsamaisoa hammoho le lehlabathe, mobu, litšepe, mashala kapa khalase.Lipalangoang hammoho le lintho tse chefo, tse senyang le tse tukang li thibetsoe ka thata.
