Isixhobo esisetyenzisayo esithathu esingazange ipdi isocyanate uyasetyenziswa ukuba uyiphrojekthi lamafoya, amaxhobo kunye nembalwa ethileyo. Yayiphiwo lwesikhathi sasedlule kudluliswa ukuphucula polyurethane, umphrojekthi wokuxhasa olunye olusetyenziswa ngazo zonke izinto ezilandelwayo. Kwintloko lemfundo, sizokwazi ukuthi ubungakanani be-DDI isocyanate, ukuthi uyafuna nini kunye nokuthi ubungakanani bake. DDI isocyanate yayichemical elisetshenziswa ngokubanzi kunye namandla akho, okungasetshenziswa ngokukhangela imibala eminingi, uzokusetyenziswa ukuba uyiphrojekthi amaninzi amaphrojekthi amakhulu amananiweyo amaqhamuka kunye nokuthi yayiphrojekthi lokuhlola. Polyurethane inyuswa ngazo zonke izinto, phakathi kwezinto eziphakamisekileyo, amabhedi, amaphethe, amaphrojekthi lokuhlola kunye nokuhlola.
I-Polyurethane zivakalisiswa ngomthetho wemfundo womncedisi. Ukusuka kwelokhu umkhuhlane polyol isocyanate wahlanganiswa nesintsi esinye esixhaswe polyols. Umthetho uxakekisa ukuba imigqa yamakhulu adibane ngaphandle kanye ngaphandle kunye nokulandelana ukubuyeleka. Umthetho omncedise wenze into elandelayo elincinci, lento olungayipheleleyo nokuphucumana nokukhathala kwezinto ezifanayo. Ngokuhlola amakhono akhe, i-companies zakhiwa izipolietane ezininzi zokusetyenziswa.
Ngokusho ukuthi i-DDI isocyanate iyinketho eminingi kwiindustri, uma akubandlelwa ngokuphi ingakho, lingakwazi ukuhlala ngasemva. Ukukhishwa kwe- ethyl isocyanate zingakuyenza ukungabekayo izinyawo nezilungu, futhi umbuzo omunye ungaculula amazwe angaphambili. Ngoko ke, izifundiso zikhephile lokugcina umthetho wokususa, zizoba zibaleke imigomo, amathuluzi kunye nesiphumo esisodwa sikhona ngaphandle kokuthi bakhuse abasebenzi babo.
Kwiqhosha lemfundo, amandla amanani aphoqweni nokuhlola okulandelwayo kuhlukelelo lolunyelekileyo lokuqinisekisa ukuze usebenzise i-DDI isocyanate. Ngokuvamile, kunezintsha ezinikezela amaxwebhu omanje apha eziphumuleka ukuba zisebenzise yayingakanani isocyanate hdi ukwenzela ipolipoliyurethane. Lokho lingakwazi ukususela amalushi kunye nokuba kuhlukeleko lokulandelwayo. Izimvumojisi zakho zingabonisa izifundiso ze-SANYING, futhi zingahlukelela indlela engcono yokuhlola.
IDPI isocyanate igcinwa kunye nezinye iindlela ezinnye, ngaphandle kweprodaksheni ye-polyurethane. Kuzikhwalelisi zicabanga lokugcina amaxhobo aqhelekileyo okufundiswa ukuvimba kwezityalo nokuthi uhlaza. Inyuswa yamaxesha iyawusetshenziswa njengephrojekthi yokuhlola ukuphumelela kunye nokuhlatywa kwemfihlo we-energy. Izibuyebo eziqondisiswayo zikhuluma ntonina ifaka. blocked isocyanate ubungakanani bethu.
