Ko te PPDI he 1,4-Phenylene diisocyanate parakore (PPDI), ko te nama CAS ko 104-49-4. Ko te PPDI he kaiwhakaora matatau / he whakaroa mekameka mō ngā elastomers thermoplastic polyurethane (PU). He tino pai te mahi hihiri o ngā elastomers whakarewa PPDI. Ko te painga kitea ko ngā wira tere-teitei i hangaia me te PPDI ka taea te tu mo te pāmahana teitei ake i raro i te mahi/nekehanga tere me te haere tonu. Nō reira, he otinga pai ngā wira PPDI mō te hunga e hiahia ana ki te roa o te ora, te kaha uta nui me te ātete wera nui. I te nuinga o te wā, he pai te ātete ki te pakū, te haehae me te tapahi o ngā elastomers PU ki te whakataurite ki ngā rapa hangai. Ahakoa he rite te hanganga, te pakeke me ngā āhuatanga modulus o te PPDI me te MDI ki te whakataurite ki te TODI, he iti ake te ōwehenga molar o te polyol ki te polyol o te isocyanate i roto i te PPDI. Ko te tikanga, he ngāwari ake ngā elastomers momo PPDI i ngā elastomers polyurethane momo MDI me te momo TODI tuku iho. I roto i ngā elastomers polyurethane katoa, e mōhiotia ana ngā mea e hangai ana ki te PPDI mō ngā wira tino taumaha, arā, ngā potae mō ngā forklifts, ngā waka me ngā waka rererangi; ngā roera ārahi, ngā wira mō ngā mīhini; ngā roera reti tere teitei me ērā atu. I roto i te poto, ko te elastomer momo PPDI te whiringa pai mō ngā tono o te iti rawa o te pao me te pāmahana teitei. I ēnei rā, e whakamahia whānuitia ana te kaihoko whakamaroke PPDI i roto i ngā hua TPU hei whakaroa mekameka matua, ā, kei te whānui haere tonu te tono, tae atu ki ngā mowhiti-O, ngā hiri waipēhi, ngā whetu hononga me ngā mata squeegee tā mata.
Nā ōna painga whakamiharo o te wera, te ātete ki te pakaru, te haehae me te tapahi, ka whakamahia whānuitia ngā elastomers PPDI ki ngā ahumahi e hiahia ana kia kore e rerekē te āhua, kia roa te wera. Ko te PPDI te kaitākaro matua i roto i te TPU (elastomer polyurethane thermoplastic). Ko ngā hiri waipēhi, ngā horoi, ngā hiri piston, ngā mowhiti-O, ngā hiri tokotoko, ngā pūrei e hiahiatia ana kia ātete ki te wera me te ātete ki te pēhanga he wāhanga nui anō o te kaihoko whakamaroke PPDI. Kāore e whakahuatia ngā potae mō ngā forklifts, ngā waka, ngā mīhini, ngā waka rererangi me ngā pūrei, ngā wira, ngā roera ārahi mō ngā huānga whakamakuku, koinei tētahi atu kāwai mō ngā elastomers momo PPDI.
Tākai: 20kg, 40kg, 50kg/pahu rino.
Te rokiroki me te kawe: He tino pāngia te PPDI e te makuku. Ka tauhohe te wai ki ngā diisocyanate katoa hei hanga i ngā matū urea kore e rewa. Kaua e tāpirihia te PPDI ki te kai, ā, kaua e waiho ki te taiao neke atu i te 30℃. Whai muri i te whakamahinga, me hiri tonu te taupoki mēnā ka pāngia. I raro i ngā āhuatanga o waho e tika ana, ka whai mana te PPDI mō te ono marama pea, mai i te rā i tukuna ai.
