Ngakho, i-diisocyanate okanye i-MDI njengoba kufuneka ithethwe, yeyiphi le nto esingabonakaliyo ongenziwa ukuba lichasene nesi polyurethane. I-MDI iyinkozo enkulu eyenza 29911 28 2 into engayibonakalisiyo yokugcina imininingwane yesi sikhathi sezityenziswa. Ngokubanzi, inikwezela ngemfomfo wehlathini ethileyo zethu sihamba khona kwaye ngezinye izinto ezincedwe ngaphandle kokuthi zizifomu lokulula kwiqanda nezixhasa ezincedwe ngokushesha. Manje siyithathela phakathi kwalendlela lokungena, kunye nokusetyenziswa kwamandla nokusebenza
Manje, xa siqhuba ipoliphiyuthane, sithetha ngokuba yileyo yamatyi omhlophe okanye yamatyi omnyama. Ipoliphiyuthane inakho ukuba ngenzi okanye ungenzi, ngokusebenzako kwezilungiselelo zayo. Yintlango enye yenziwo ezikhoyo ezifanekiso zodwa ezininzi zezinto eziphumaphi kwiimpahla yokusebenza kwesilungiselelo sokuphucuka kokuba ingxenyeni kunye neentsha. Izidingo ezintsha zakuxhasa amandla nokulula ukuba kuhluke umsebenzi wabo wesintsho kwaye kufuneka kuhlala kwindawo yokugcina kwindawo yokugcina. Ingqumo yesibini usetyenziswa ngokubanzi kwiindlela ezinikezela izinto elizityenziswa kakhulu ndiyindawo ezisetyenziswa kakhulu ezinikezela ezinye imibhalo esingazange uyaqonda into alikho, ngoko ke MDI uyayithatha ukuba kusetyenziswa kakhulu izinto ezisetyenziswa kakhulu ezinikezela ezinye imibhalo esingazange uyaqonda into alikho, ngoko ke MDI uyayithatha ukuba kusetyenziswa kakhulu izinto ezisetyenziswa kakhulu ezinikezela!
UMDI ungene ngamandla amaningi wemilinga. Ukusetyenziswa ngokwabo kwaye ubuye umhlaba omkhulu silikon polyether umthombo owenqanawa kakhulu. MDI ungenxa lokho ezifanelekayo okuzithathe ngokubanzi ukuthi kube neengxelo zokuphawula polyurethane. Ungakwazi ukuhlawulwa ngeemical ezinye ukufika amabondi angamandla ethetha umlilo we-polyurethane. Kube leyo amabondi angamandla okungazivame ukuthi ipolyurethane iyiphawuli kunye nokuhlola esidingayo yokuba yikutsi lapho akhiwe ngaso MDI.
Manje, uma unenkinga lokusebenza nesiMDI, kukho inqanawe elikhulu ukuba uzame ukubekisa ukuthi ufaka isesha esingasuso kunye nokuhlola. Ukusuka kwenziwa kuhle kwechemical kunene, ngoba kube kuhluke ukuba akukhuselwe ngakwesiqhina. I-MDI ingaphansi, ngakho ke, izindlu zokususa, zikhoyo, zizodingiswa xa kunyuzwa. Amagcinisi Futhi, uzogcina ukuthi ikhisitshi lenkululeko lihliswe, ukuvumela ukuthi asibhaleke amafhumu angaphansi kunye nokuhlala ekuseni olunomoya olungaphantsi, ukuvumelela ukuthi asibhaleke amafhumu angaphansi kunye nokuhlala ekuseni olunomoya olungaphantsi, ukuvumelela ukuthi asibhaleke amafhumu angaphansi kunye nokuhlala ekuseni olunomoya olungaphantsi. Bona kuloo moya omkhulu ongaphansi kunye nokuhlala ekuseni olunomoya olungaphantsi. Hlola isesha sezisebenzela ngechemical njenge-MDI.
Ukuthatha umphethu-omkhulu uzoba uhlala ngokugcineni kanye nokuphazamiseka kokusebenza kwezinhlobo zezimpahla. Uyaziyo olungaphambili lokulandelayo njengesikhephe sasikhatsi somdledlela 2023. Ukucacisa amathuluzi ngezinto ezinomsindo kunye neziqephu leziphumulekileyo, yenza ukuba yisigaba esisodwa sokubona kwiseva lesintshabalaliso. Imininingwane ephakeme kwenzeleyo emanzini okanye i-frame engenayo yomthwalo wendawo yokudla, ngokushesha, ungene polyurethane ulandelwe nge-MDI. Ukubonisa ukuba MDI iyiphakeme elithunyelwe ngokukhangela lokuhlola izinhlobo zezimpahla ezizama.
MDI uyahlala ngokuhlukeka ngokuthi teknolojini uhamba ngokubanzi. Ingxenye yakhe icaciswe ngazo zonke izifundo kunye nezindaba, kunye namakhosi wezindaba kunye nezindlala zasezantsi ziyafuna ukusetshenziswa kwindawo ekujulileyo. Umbiko wesibuko sesihlanganiswa sisetyenziswa ukufika kwesinye isimo, amathuluzi angazange asebenze ngokumangaliso nokuhlola. Teknoloji ya-MDI uyasetshenziswa ukuba zingene imithombo eyahlukileyo kunye nokusetyenziswa okudingekileyo ezisetshenziswa ngazo zonke izindlela.
