I-HDI Unit yi-Chemical esingazixhaswe njengomsebenzi wasefactory okanye indawo yesayensi. Leli chemical liphilile kakhulu xa lihlola nge-Chemicals abanye, njenge-polyols, ukwenzela iphroduct engithi ipolyurethane yamaphu zokungqinisekisa . i-Polyurethane inikezwa ngamandla emibhaleni yamaninzi. Ngenxa yohlobo olwandlelwanga lokhu, i-HDI isocyanate kusetshenziswa ngamandla emifanekiso, kuthe ku-solids nokulula.
Ngokuqinisekileyo kweHDI isocyanate, iinkxaso engezi zonke zizosetshenziswa ngokusho, iyinhlangano enkulu. Naye ifanele yezinto eziningi, njengezinto zophawuli, uzame nokugluze kanye nokusekhela, ezisetshenziswa ngokusho kwindawo ezininzi zokubhedla nokusetshenziswa. Futhi, HDI polyol isocyanate ukusetyenziswa kwenziwe kwiiphrogesi yokuqinisekisa ngezintsha nobungathu obungayo, okufuneka kuzosetshenziswa ngemibhokisi yokugcina, amasitolo, kunye nomunye umnotho wabanye. i-HDI isocyanate, okungayiqulwa nokubanjwa ngezinto ezimbini ezilindelekelwayo, yiingxenye elinesiko elizusetshenziswa ngeminingi emibhalweni yamaphrogesi.
Ungavuselelwa ukuphela kwisicwangciso eseqedweni lokusebenza uma ungene ku-HDI polyol kunye no-isocyanate eyayingqinelene nezinye izinto zokuthola ukuthi uhlala ngenqanawe kanye nezindlela ezindala ezinikezeliyo, futhi ngokwesikhatsi sithile siyazi ukuthi uzogcina ukusetyenziswa komphilo wesikhephe ngokusebenzisa imibhalo yokugcina, phakathi kwezintlanti, nezinhlobo zakho. Ngokuhlelo lokhu, le mibhalo azobhekisisa kwezinto ezingaphambili zokungcono lwe-chemical. Kuningi lokulandelana nohlangothi oluhlaza kunye nokugcina ukudla kokuthi kungcono, ukusuka kwindawo engazange uthungele amagase amahhusha a-HDI isocyanate.
Umbuzo omphumelelo lwesiqephu sika-HDI isocyanate njengomphulo wokusebenzisa polyurethane yintoni yokulandelwa kwezinto ezifakelwayo ngamandla nokungavunyelwe. Izinto zokuqapheleka polyurethane ezibonakalisiweyo nge-HDI isocyanate zikhethwe ngokuthi zihlaba amandla. Zingavunyelwe kakhulu, ngakho zakhiwo nokuba zinakwazi ukubhala nokubhokisela ngaphandle kokuhambisana ngasemva. Lokhu liphathelise kakhulu lokuncedisiweyo kumazinye imigomo kunye nokukholelwa ukuthi izinto zizobenzi futhi zizosetshenziswa ngaphandle kokuhlola.
I-HDI isocyanate iyigama elithi i-solid ne-liquid. Kusetyenziswa ngokubanzi ukufakwa kwezinto zemfuphi nokulayishwa, oku kuhlu kuzo kuhlola izinto zokuthengisa ukuthi zikhono ngenxa yokuqasha amaninzi. i-Liquid HDI isocyanate kusetshenziswa ngokuba kunye nothile ukwenza amaphu, okungabangako obabi noma obukhulu ngokunyuka kwesikhephe. Izinyathelo ezidinga ze-HDI isocyanate zihamba ngamandla ezisisekelweyo lokuhlola ukuthi zikhono ngenxa yokushetha lokusebenzela kwisebe sasebenzi kunye nokuthi ubungakanani bethu.
