PPDI e hloekileng 1,4-Phenylene diisocyanate (PPDI), nomoro ea CAS ke 104-49-4. PPDI ke sesebelisoa se tsoetseng pele sa ho phekola / ketane ea li-extensions tsa polyurethane (PU) thermoplastic elastomers. Li-elastomer tse thehiloeng ho PPDI li hlahisoa ka ts'ebetso e matla haholo. Molemo o totobetseng ke hore mabili a lebelo le phahameng a hlahisoang ka PPDI a ka emela mocheso o phahameng haholo tlas'a ts'ebetso / motsamao o potlakileng le o tsoelang pele. Ka hona, mabili a thehiloeng ho PPDI ke tharollo e nepahetseng bakeng sa litlhoko tse sebetsang nako e telele, matla a maholo a ho laela le litlhoko tse phahameng tsa ho hanyetsa mocheso. Ka kakaretso, li-elastomer tsa PU tse nang le li-abrasion tse ntle haholo, tse tabohang le tse sehiloeng ha li bapisoa le liraba tsa maiketsetso. Leha PPDI le MDI li na le sebopeho se ts'oanang, boima le thepa ea modulus ha e bapisoa le TODI, isocyanate e na le tekanyo e tlase ea molar ea polyol ho polyol ho PPDI. Ha e le hantle, li-elastomer tsa mofuta oa PPDI li tenyetseha ho feta li-elastomer tsa setso tsa mofuta oa MDI le TODI-mofuta oa polyurethane. Har'a li-elastomers tsohle tsa polyurethane, tse thehiloeng ho PPDI li tsejoa ka mabili a sithabetseng haholo, ke hore lithaere tsa forklift, likoloi le lifofane; lirolara tse tataisang, mabili a mechini; lirolara tsa skate tsa lebelo le holimo joalo-joalo. Ka bokhutšoane, elastomer ea mofuta oa PPDI ke khetho e nepahetseng bakeng sa lits'ebetso tsa abrasion e tlase le mocheso o phahameng ka ho fetesisa. Matsatsing ana, moemeli oa pheko oa PPDI o sebelisoa haholo ho lihlahisoa tsa TPU e le "chain extender", mme ts'ebeliso e ntse e hola, ho kenyeletsoa li-O-rings, litiiso tsa hydraulic, coupling stars le li-blade squeegee tsa khatiso ea skrineng.
Melemo bakeng sa melemo ea eona e sa tloaelehang ea mocheso, abrasion, tabo le khanyetso e sehiloeng, li-elastomers tse thehiloeng ho PPDI li sebelisoa haholo liindastering tse hlokang ts'ebetso e thata, e tšoarellang mocheso. PPDI ke sebapali sa bohlokoa ho TPU (thermoplastic polyurethane elastomer). Litiiso tsa Hydraulic, wiper, piston seals, O-rings, rod seals, pulleys tse neng li kopa ho hanyetsa mocheso le khatello ea khatello ke likarolo tse ling tsa bohlokoa tsa PPDI e phekolang. Ha re bue ka lithaere tsa forklift, likoloi, mechini, lifofane le li-pulleys, mabili, lirolara tse tataisang bakeng sa lintho tse kolobisang e leng sehlopha se seng sa li-elastomer tsa mofuta oa PPDI.
Ho paka: 20kg, 40kg, 50kg / moropa oa tšepe.
Ho boloka le ho tsamaisa: PPDI e na le maikutlo a mangata haholo ho mongobo. Metsi a kopana le diisocyanate kaofela ho etsa lintho tse tsoang ho urea tse sa keneng. Se ke oa beha PPDI hammoho le lijo 'me u qobe ho pepeseha sebakeng se kaholimo ho 30℃. Ka mor'a ho sebelisoa, sekoahelo se tlameha ho koaloa hang-hang haeba ho sa sebetse hantle. Tlas'a maemo a loketseng a kantle, PPDI e sebetsa bonyane likhoeli tse tšeletseng ho tloha ka letsatsi leo e rometsoeng ka lona.
