I-PPDI yi-1,4-Phenylene diisocyanate (PPDI) ecocekileyo, inombolo ye-CAS yi-104-49-4. I-PPDI sisixhobo sokwandisa i-anti-corrosion/chain esiphucukileyo se-polyurethane (PU) thermoplastic elastomers. Ii-elastomers ezisebenzisa i-PPDI-based casting zibonakala zisebenza kakuhle kakhulu. Inzuzo ecacileyo kukuba amavili akhawulezayo enziwe nge-PPDI angamela ubushushu obuphezulu kakhulu phantsi kokusebenza/ukunyakaza okukhawulezayo nokuqhubekayo. Ke ngoko, amavili asekelwe kwi-PPDI sisisombululo esifanelekileyo kwezo mfuno zihlala ixesha elide, amandla amakhulu okulayisha kunye neemfuno zokumelana nobushushu obuphezulu. Ngokubanzi, ii-elastomers ze-PU ziphawulwa ngokukrazuka okuhle kakhulu, ukukrazula kunye nokumelana nokusika xa kuthelekiswa neerabha ezenziweyo. Nangona i-PPDI kunye ne-MDI zineempawu ezifanayo, ubunzima kunye ne-modulus xa kuthelekiswa ne-TODI, i-isocyanate inomlinganiselo ophantsi we-molar we-polyol kwi-polyol kwi-PPDI. Ngokusisiseko, ii-elastomers zohlobo lwe-PPDI ziguquguquka ngakumbi kune-MDI-type kunye ne-TODI-type polyurethane elastomers zemveli. Phakathi kwazo zonke ii-polyurethane elastomers, ezisekelwe kwi-PPDI zaziwa ngamavili axinene kakhulu, oko kukuthi, amatayara ee-forklifts, izithuthi kunye neenqwelo moya; ii-guide rollers, amavili oomatshini; ii-skate rollers ezikhawulezayo njalo njalo. Ngamafutshane, i-PPDI-type elastomer yeyona ndlela ifanelekileyo yokusebenzisa i-abrasion ephantsi kunye nobushushu obuphezulu. Kule mihla, i-PPDI curing agent isetyenziswa kakhulu kwiimveliso ze-TPU njenge-main chain extender, kwaye isicelo siyaqhubeka nokukhula, kubandakanya ii-O-rings, ii-hydraulic seals, iinkwenkwezi zokudibanisa kunye nee-squeegee blades ze-screen printing.
Iingenelo zeengenelo zayo ezingaqhelekanga zobushushu, ukukrazula, ukukrazula kunye nokumelana nokusika, ii-elastomers ezisekwe kwi-PPDI zisetyenziswa kakhulu kumashishini afuna imisebenzi enzima yokuguquguquka, ehlala ixesha elide kubushushu. I-PPDI ngumdlali ophambili kwi-TPU (thermoplastic polyurethane elastomer). Ii-hydraulic seals, ii-wipers, ii-piston seals, ii-O-rings, ii-rod seals, ii-pulleys ezicelwe ukumelana nobushushu kunye nokumelana noxinzelelo zezinye iindawo ezibalulekileyo ze-PPDI curing agent. Ingasathethwa ke ngamatayara ee-forklifts, izithuthi, oomatshini, iinqwelomoya kunye nee-pulleys, amavili, ii-guide rollers zezinto ezimanzisa amanzi ezizezinye ze-PPDI-type elastomers.
Ukupakisha: 20kg, 40kg, 50kg/idrama yentsimbi.
Ukugcinwa kunye nokuthuthwa: I-PPDI inovakalelo olukhulu kumswakama. Amanzi asabela kuzo zonke ii-diisocyanates ukuze enze ii-urea derivatives ezinganyibilikiyo. Musa ukufaka i-PPDI kunye nokutya kwaye uphephe ukuvezwa kwindawo engaphezulu kwama-30℃. Emva kokusebenzisa, isiciko kufuneka sivalwe ngoko nangoko xa kukho ukungasebenzi kakuhle. Phantsi kweemeko ezifanelekileyo zangaphandle, i-PPDI isebenza iinyanga ezintandathu ubuncinane ukususela kumhla efikelelwa ngawo.
