Izakhiwo ze-physicochemical: I-PPDI iyisiqina esimhlophe esiqhekekile. Indawo yokuncibilika: 94 °C. Indawo yokubila: 110~112 °C (3.3kPa) Ubuningi: 1.17g/cm3
I-PPDI iyi-1,4-Phenylene diisocyanate (PPDI) emsulwa, inombolo ye-CAS ingu-104-49-4. I-PPDI iyi-ejenti yokwelapha ethuthukisiwe/izandisi zeketanga zama-elastomer e-thermoplastic e-polyurethane (PU). Ama-elastomer asekelwe ku-PPDI abonakala ngokusebenza okuhle kakhulu okuguquguqukayo. Inzuzo esobala ukuthi amasondo asheshayo akhiqizwa nge-PPDI angamelela izinga lokushisa eliphakeme kakhulu ngaphansi kokusebenza/ukunyakaza okusheshayo nokuqhubekayo. Ngakho-ke, amasondo asekelwe ku-PPDI ayisisombululo esifanele salezo zidingo zokuphila isikhathi eside, amandla amakhulu okulayisha kanye nezidingo zokumelana nokushisa okuphezulu. Ngokuvamile, ama-elastomer e-PU abonakala ngokuklwebheka okuhle kakhulu, ukuklebhula nokumelana nokusika uma kuqhathaniswa namarabha okwenziwa. Naphezu kokuthi i-PPDI ne-MDI zinezakhiwo ezifanayo zokwakheka, ubulukhuni kanye ne-modulus uma kuqhathaniswa ne-TODI, i-isocyanate inesilinganiso esiphansi se-molar se-polyol ne-polyol ku-PPDI. Ngokuyisisekelo, ama-elastomer ohlobo lwe-PPDI aguquguquka kakhulu kune-MDI-type kanye ne-TODI-type polyurethane elastomer yendabuko. Phakathi kwazo zonke ama-elastomer e-polyurethane, asekelwe ku-PPDI aziwa ngamasondo acindezelwe kakhulu, okungukuthi amathayi e-forklift, izimoto nezindiza; ama-guide rollers, amasondo emishini; ama-skate rollers anesivinini esikhulu njalo njalo. Ngamafuphi, i-elastomer yohlobo lwe-PPDI iyisinqumo esifanele sokusetshenziswa kwe-abrasion ephansi kakhulu kanye nokushisa okuphezulu kakhulu. Namuhla, i-PPDI curing agent isetshenziswa kabanzi emikhiqizweni ye-TPU njenge-main chain extender, futhi uhlelo lokusebenza luyaqhubeka nokukhula, kufaka phakathi ama-O-rings, ama-hydraulic seal, izinkanyezi zokuxhuma kanye nama-squeegee blades okunyathelisa isikrini.
Izinzuzo zezinzuzo zayo ezingavamile zokumelana nokushisa, ukuklwebheka, ukudabuka nokusika, ama-elastomer asekelwe ku-PPDI asetshenziswa kabanzi ezimbonini ezidinga imisebenzi eqinile yokuguquguquka nokushisa. I-PPDI iyisidlali esibalulekile ku-TPU (thermoplastic polyurethane elastomer). Izivalo ze-hydraulic, ama-wiper, izivalo ze-piston, ama-O-rings, izivalo zenduku, ama-pulleys acele ukumelana nokushisa nokumelana nokucindezela ezinye izinkambu ezibalulekile ze-PPDI curing agent. Ingasaphathwa amathayi e-forklifts, izimoto, imishini, izindiza nama-pulleys, amasondo, ama-guide rollers ezinto ezimanzisa amanzi okuyisigaba esinye sama-elastomer ohlobo lwe-PPDI.
Ukupakisha: 20kg, 40kg, 50kg/isigubhu sensimbi.
Ukugcinwa Nokuthuthwa: I-PPDI iyazwela kakhulu kumswakama. Amanzi asabela nawo wonke ama-diisocyanates ukuze akhe ama-urea derivatives angancibiliki. Ungafaki i-PPDI kanye nokudla futhi ugweme ukudalulwa endaweni engaphezu kuka-30℃. Ngemva kokusebenzisa, isivalo kumele sivalwe ngokushesha uma kwenzeka ukungasebenzi kahle. Ngaphansi kwezimo zangaphandle ezifanele, i-PPDI isebenza izinyanga eziyisithupha okungenani kusukela ngosuku elethwa ngalo.
