Diphenylmethane 4,4'-Diisocyanate (MDI) iyinye yenkcwadi eline yicala lokuhlala ukuthi ifomu engenile lichashe. Kulandelwa ukuthi kuzosetshenziswa ukuba zikhulume amaxesha ngokungcono ngezindlela ezinomsindo.
Ngaphandle Kwesihlobo Sabuhle Sakusetyenziswa
MDI yakhiwo kunye nezi zinto ezininzi ipolyurethane yamaphu zokungqinisekisa izintsha ngokuthi kuyibona ngezinto ezidingekayo lokuhlola. Ukuthi okungakho, ingakwenziwa ukusindiswa okanye ukusandula xa sifuna ukuba kufunekwe. Lento yilandel’ ukuthi liphathimiseleyo kakhulu lezinhlangothi zethu ngoba sifuna kulindelana nokuhlola umoya wemvula ngomhla, kunye nokuhlola umoya omncane ngomnye. MDI ikhangelela ukuhlola okudingekayo.
Mntanomntu Ngenkxaso
MDI ngaphandle kokuthi kuhlanganisa isithuthi esikhankanyiswanga njengesiphi. Le nto ifumaneka ukuba zinto eziphathwe nguMDI zikhankanyiswe ukubanjwa. Inqanawa yokugcina ukukhupha imigalelo kunye nokulindela ukuba amaxhobo kunye neziqhaza ezinomsindo azikhelekanga xa zihamba umoya omkhulu okanye izinsimbi ezininzi zihlala. Lokhu libonakalisi ukuvumela usosathu kunye nokuhlola kwabo abantu abamazinye phakathi komkhaya bazo kunye nokusebenza.
Kusenziwa ukuthi ingxoye
Lento elikhoyo lokunye ukuthi MDI iyinkozo yokugcina emva kokuthi kuziphatha ngokubanzi kakhulu. Okuningi lokho lihlola indalo, lokhu liphathimiseleyo kakhulu kuzo zonke izilwandle ezivimbini ezingaphambili. MDI emva kokuthi Ipoliyuthane Amakhayezeli KweSithuthu zingakwenziwa ukusindiswa kwezilwandle zakwetu nokukhupha ukuba amadoda angavela amaqhawekazi amaphantsi akhona ulwandle oluncedileyo nokulondoloza.
Ukuya Ngaphambi Kwesikhatsi Kunye Nokuqhubeka
AMDI ayiqhuba ukusukela nokuhlola kakhulu kunye nokuhlola kakhulu amaphu zokungqinisekisa . Oku kufuneka izinto ezisebenzisa i-MDI zibekwe ngaphandle kokuthi zonke izinto ezisebenzisa amagcinde asele. Ngokubanzi, oku kuthathu ngendawo yokubhulwa kunye nokusebenza, apho amathetho asetyenziswa kunye neziqhaza ezisenzelayo ezincedwayo. Ndizobona ukuba amasayithi akhona kunye neziphi zezintloko zethunywa ngu-MDI.
Iindlela Ezininzi Zokusebenza Kwisayithi Nokuhlanganisa Izinto
I-MDI iyinhlobo elithile kusayithi kunye nokuhlanganisa izinto ngeemva kweendlela ezimbili. Ukuthi lokhu kuyenza ukuba kube yindlela engakwenziwa ukwakhiwa kweemfanelo engeeni. Kwesayithi esincinci kunye nokuphucukeleka kwemoto kunye nemibhalo, i-MDI ifanele kwiqhosha lokusebenzela izinto ezilandelwayo ezinikezeliyo. Isetshenziswa ngaso sakhulu sesikhatsi, isenzo sokugcwalisa kunye nokuhlola kufuneka kube ingxelo yesicelo sokugcina.
