Lisebelisoa
(ningbo) Lisebelisoa tsa mantlha tsa Taiwan Formosa Plastics pp5090t:
PP ke thepa ea semi crystalline.E thata ho feta PE mme e na le sebaka se phahameng sa ho qhibiliha.Kaha mofuta oa homopolymer PP o brittle haholo ha mocheso o le ka tlase ho 0 ℃, lisebelisoa tse ngata tsa khoebo tsa PP ke li-copolymers tse sa reroang tse nang le 1-4% ea ethylene kapa li-clamp tsa mofuta oa li-copolymers tse nang le ethylene e phahameng.Mofuta oa PP oa mofuta oa copolymer o na le mocheso o fokolang oa mocheso (100 ℃), pepeneneng e tlase, botlolo bo tlase le ho tiea ho tlase, empa o na le tšusumetso e matla.
Sekhahla sa phallo ea MFR ea PP e tloha ho 1 ho ea ho 40. PP e nang le MFR e tlaase e na le khanyetso e ntle ea tšusumetso empa matla a tlaase a tlaase.Bakeng sa lisebelisoa tse nang le MFR e tšoanang, matla a mofuta oa copolymer a phahame ho feta a mofuta oa homopolymer.Ka lebaka la kristale, sekhahla sa ho putlama ha PP se phahame haholo, ka kakaretso ke 1.8-2.5%.'Me ho tšoana ha tataiso ea shrinkage ho molemo haholo ho feta ea PE-HD le lisebelisoa tse ling.Ho eketsa 30% ho eketsa khalase ho ka fokotsa shrinkage ho 0.7%.
Mofuta oa Homopolymer le lisebelisoa tsa mofuta oa PP oa copolymer li na le khanyetso e ntle ea ho monya mongobo, ho hanyetsa kutu ea acid-base le ho hanyetsa ho qhibiliha.Leha ho le joalo, ha e khone ho hanyetsa monko o monate oa hydrocarbon (joaloka benzene) le motsoako oa hydrocarbon oa chlorine (carbon tetrachloride).PP ha e na khanyetso ea oxidation mocheso o phahameng joalo ka PE.
Ho latela ts'ebetso e kaholimo, PP e loketse lihlahisoa tse latelang:
1. Ente: li-valve, lisebelisuoa, lik'hasete, likoloi, ho koaloa, lisebelisoa tsa motlakase, libotlolo tsa metsi, lijana tsa lijo, thepa ea ka tlung, lintho tsa ho bapala, lisyringe tse sa tlatsoang pele.
2. Extrusion: lakane e teteaneng, lakane, phala, lehlaka, tepi e tlamang, letlapa la ho ngola, Letlapa la filimi ea BOPP le hlobo.
3. Ho bopa: botlolo.
4. Thermoforming: terei, sekotlolo, senoelo sa jelly, senoelo sa metsi.
5. Khoele e bataletseng: mokotla o lohiloeng, mokotla oa setshelo, k'hapete.
