I-DUPONT, I-EXXONMOBIL YATHUTHUKISA AMA-TPV AMASHA EZIMPAWU ZEZINTAKA
Ibhizinisi le-DuPont Transportation & Industrial kanye ne-ExxonMobil Chemical's specialty elastomers lithuthukise ama-thermoplastic vulcanisates (TPVs) amasha ophawu lwesikhunta ekhoneni lezimoto.
Lezi zinkampani ezimbili zashintsha izithasiselo ezijwayelekile ze-organic slip zafaka izithasiselo ze-DuPont ezenziwe ngobunjiniyela be-silicone ukuthuthukisa “isizukulwane esilandelayo” i-Santoprene TPV, kusho isitatimende esihlanganyelwe mhla zingama-27 kuNhlangulana.
Uma kuqhathaniswa namabanga ayo angaphambilini, into entsha ye-TPV inikezela ngesibopho esithuthukisiwe kuma-substrates erabha e-ethylene propylene diene monomer (EDPM) kanye ne-coefficient ephansi ye-friction (COF) ukuze uvuleke kalula futhi uvale iminyango namafasitela.
Umndeni wemikhiqizo we-Santoprene TPV B260 uphinde ulethe izakhiwo zokugeleza ezithuthukisiwe, ukumelana nokuhuzuka kanye nokuzinza kokukhanya kwe-ultraviolet (UV), izinkampani zengeza.
Ukusebenzisana, ngokusho kukaChristophe Paulo, umphathi wezokukhangisa, iDuPont “ibeke isisekelo” samaphrojekthi wesikhathi esizayo kusetshenziswa ubuchwepheshe be-silicone ukuxazulula izinselelo zemboni.
Ukusabela esidingweni samakhasimende, i-ExxonMobil Chemical ifune ukuthuthukisa ukubopha kwe-Santoprene TPV kunjoloba ye-EDPM ngenkathi ikhulisa ukusebenza kwayo kokuslayida.
Kodwa-ke, ukunciphisa i-COF ukuze kwandiswe ukusebenza kwe-sliding kungaba nomthelela omubi ekuhlanganiseni, kusho inkampani.
Ukuze kubhekwane nalokho, i-ExxonMobil ihlanganyele ne-DuPont ukuhlola ukusetshenziswa kwezithasiselo zayo ezisekelwe ku-silicone.
"Ithimba labathuthukisi be-DuPont lithole ukuthi ukusebenzisana phakathi kwe-silicone polymer enesisindo se-molecular ephansi kanye ne-ultra-high molecular weight silicone polymer kuletha i-COF ephansi i-ExxonMobil Chemical ebifunwa," kusho isitatimende..
