Izakhiwo ze-Physicochemical: I-PPDI iqinile elimhlophe elingenalutho. Indawo yokuncibilika: 94 °C. Indawo yokubilisa: 110~112 °C (3.3kPa) Ukuminyana: 1.17g/cm3
I-PPDI ihlanzekile i-1,4-Phenylene diisocyanate (PPDI), inombolo ye-CAS ngu-104-49-4. I-PPDI iyi-ejenti yokwelapha ethuthukisiwe / izandisi zamaketanga zama-thermoplastic elastomers e-polyurethane (PU). Ama-elastomer okusakaza asuselwa ku-PPDI afakwe ngokusebenza okuhle kakhulu okuguquguqukayo. Inzuzo esobala ukuthi amasondo anesivinini esikhulu akhiqizwe nge-PPDI angamela izinga lokushisa eliphakeme kakhulu ngaphansi kokusebenza/ukunyakaza okushesha nokuqhubekayo. Ngakho-ke, amasondo asekelwe ku-PPDI ayisixazululo esifanelekile salezo zidingo ezisebenza isikhathi eside, umthamo omkhulu wokulayisha kanye nezidingo zokumelana nokushisa okuphezulu. Ngokuvamile, ama-elastomer e-PU abonakala ngokuhuzuka okuhle kakhulu, ukudabuka nokusikwa ukumelana nokuqhathaniswa namarabha okwenziwa. Naphezu kwe-PPDI ne-MDI inokubunjwa okufanayo, ubulukhuni kanye nezakhiwo ze-modulus uma kuqhathaniswa ne-TODI, i-isocyanate inenani eliphansi le-molar ye-polyol ku-polyol ku-PPDI. Ngokuyisisekelo, ama-elastomer ohlobo lwe-PPDI aguquguquka kakhulu kunohlobo lwe-MDI lwendabuko kanye ne-TODI-type polyurethane elastomers. Phakathi kwawo wonke ama-elastomer e-polyurethane, asekelwe ku-PPDI ayaziwa ngamasondo acindezeleke kakhulu, okungukuthi amathayi ama-forklift, izimoto kanye nezindiza; ama-roller, amasondo emishini; high speed skate rollers nokunye. Ngamafuphi, i-elastomer yohlobo lwe-PPDI iyinketho ekahle ekusetshenzisweni kokuhuzuka Okuphansi kanye nezinga lokushisa eliphakeme kakhulu. Namuhla, i-ejenti yokwelapha ye-PPDI isetshenziswa kakhulu emikhiqizweni ye-TPU njenge-chain extender, futhi uhlelo lokusebenza lulokhu lunwebeka, kufaka phakathi ama-O-rings, ama-hydraulic seal, izinkanyezi ezihlanganisayo nama-squeegee blades wokuphrinta isikrini.
Izinzuzo ngezinzuzo zayo ezingavamile zokushisa, ukuhuzuka, ukumelana nokukhala nokusika, ama-elastomer asekelwe ku-PPDI asetshenziswa kabanzi ezimbonini ezidinga ukuguquguquka okuqinile, imisebenzi ehlala isikhathi eside ukushisa. I-PPDI iyisidlali esibalulekile ku-TPU (thermoplastic polyurethane elastomer). Izigxivizo ze-hydraulic, ama-wiper, ama-piston seal, ama-O-rings, ama-rod seal, ama-pulleys acele ukumelana nokushisa nokumelana nokucindezela ezinye izinkambu ezibalulekile ze-agent ye-PPDI yokwelapha. Ingasaphathwa emathayi ama-forklift, izimoto, imishini, izindiza nama-pulleys, amasondo, amarola aqondisayo wezinto ezimanzisa okungesinye isigaba sama-elastomer ohlobo lwe-PPDI.
Ukupakisha: 20kg, 40kg, 50kg/isigubhu sensimbi.
Isitoreji nokuhamba: I-PPDI izwela kakhulu kumswakama. Amanzi ahlangana nawo wonke ama-disocyanate akhe okuphuma kokuphuma kwe-urea engancibiliki. Ungafaki i-PPDI kanye nokudla futhi ugweme ukuvezwa endaweni engaphezu kuka-30℃. Ngemuva kokusetshenziswa, isivalo kufanele sivalwe ngokushesha uma kwenzeka ukungasebenzi kahle. Ngaphansi kwezimo ezifanele zangaphandle, i-PPDI isebenza izinyanga eziyisithupha okungenani kusukela ngedethi edilivwe ngayo.
