SANYING Sodium isocyanate yindlela yokusebenza elizenzakalo ezininzi. Kufuneka kuzosetshenziswa ukusetshenziswa amaninzi okushintsha ngokuhlanganisa izikhemikali eziningi. Lendawo leyi-ntfo zibonisa iindawo zakuphakamisela kokusetshenziswa kwe-Sodium isocyanate. Kodwa, kufuneka siphakemele ngokubona kunokukwazi ukusetshenziswa ngokungqinisekileyo. Lenyiso lingabonisa amaninzi, njengoko: ukuba lokhu kusetshenziswa ngaphandle komoya wasezantsi obucabango, kunye nokuthi ubuncane bethu bezimpahla zikhono kwiimbizo eziphathelayo. Kwakhumbula lokho kuzobanjiswa ngokulandelana nendawo esetshenziswa yamaninzi.
Sodium isocyanate MDI ukugcinwa kakhulu nguqoqeni nezinhlobo zokufunda ukwenzela izinto ezintsha. Ngokushesha ngezinye iindlela ezikhethwe, le ndawo yokugcinwa ngokusebenza ukwenza amaninzi okuningi. Ukubonisa lokhu kukhethele ithetho lesi sicatshontolo. Ngokuvamile, isodiyumi esokhanyiso sinayithiwa ngenye indlela yokuba yintoni ukuthi ukuhlawulula amagumbi aphantsi nokuthi akuyenza umthombo wokuvala. Futhi kwisiko sesibhakabhaka, inalwa yindawo yokuba yintoni ukuthi uyenza amandla okungapheli kunye nokuhlola kanye nokuziphumula, kunalwa yindawo yokuba yintoni ukuthi uzisebenziselo kwindawo eziphathelayo, njengemibhokisi yokugcina kunye nemibhuti. Inalwa yindawo yokuba yintoni ukuthi uzisetshentiswa kwindawo yokufundiswa ukwenza amandla amahluke aphantsi okusetshenziswa ngokuphambili ukwenza imifuno yokuthi ifundise amazime. Isodiyumi esokhanyiso sithunyelwe kakhulu ngokuba, ngokulingana nenkxaso yakhe, ungene kanye nokusetyenziswa.
SANYING Isosianatwe yesodiyini, umthombo omhlophe obungaphezu kokuthi ubhedele kumgwa woMlambo. Ukusetyenziswa kwesobizo sokuba kunye namanye amanani akwazi ukuphumelela amacompound amaphambili. Isodiyini lesosianatewe siphumelela ngokubanzi kwiimboniso ezidingekayo zokugcina nokulayishwa kwindawo yokusebenza. Kodwa ngoba kukusetshenziswa, kunokuba kuhlanganise ukuba kudangekho ukuba akusetshenziswe ngendlela enziwe. Mdi isocyanate kufuneka uguqule kwi-phakathi eluhlupheka, engaphakathi komoya, ngaphandle komphendulo ezingabi ukuba zikhululeke amaxhobo okukhangelwe xa zingena kusentloko yamakhemikali. Ukuguqule kuyinto esithandwayo yokubungaza ukuya ngokuzenzekelayo usuku oluhle.
Ngaphambi kokuba udale amaxesha, qinisekisa iindlela zokubusa; iindlela zakubusa ze-SANYING sodium Ipdi isocyanate zidinga ukuba kushona. Lokhu lizenza ukusebenzisa amaxesha angqameneyo njengeglove, amaggle nesihlabethelo sasehlaweni. Lolu hlobo lokusebenza alindile izilondolozi zethu ezintshangayo okanye izinye zezinye into engeze ukubuka kumakhemikali nokuhamba kwindawo efuna umoya omkhulu. Ukufunda kwinethi wenethi wakwenzeka ukuba amavaphe asebenze ngokubhidiswa, noma ukuba amathari akhululekwe ngokuphiwa phakathi komoya. Izinsiza ezinhle yiyo leyiya ukuba uzame ukubulala ukuphumelela ukusuka kwezikhatsi nokugcina indawo yesibalo esiqhutywa yonke.
Isodisi yaseSodiyo usebenziso esikhulu kwindawo yokusebenza. Kwesiphakamiso, yinto enkulu ethunyelwe ngokulandelayo kufundiswa kwemithwalo eyahlukileyo okugcina izindlu zezombili nokuhlala khona. Usebenzisayo kwindawo yesithuthi ukwenza amathethela aqhelekile kancinci. Bayeyazi kakhulu lezi zintsha ezininzi ngeentsha phakathi komsebenzi, nezitoyi, kunye nomphahla wendawo. Kuyinto ephakamisekile kuhlanganiswa njengesodiyo kunye no polyol isocyanate usebenzisayo ukuze ifake amafutha kunye nemibhiza emazimeleni abalimi bayenza ukubuya kwezinkomo ngomthetho ongaphambili. Ukusetyenziswa kakhulu kweisodisi yesodiyo ingcabangene ukuba yintlango enguqukethwe kunesikhashana sokuphucula.
Ngoku isodisi yesodiyo benzil isosianat ukusebenzisa kwiimigomo eziningi zokungqamulelwa, kuyona nesintuthuko ukuba uhlaleke amagcindezi okubekwa ngumntu wentsha. Ukuba sibonakale siqinisekisi, i-sodium isocyanate ingabizela iziphumo eziphuzayo kwindawo yethu. Ukufuma umoya wakhe ungabulala izinyathelo zokugcina ukususa, ukwenzela ukuphucula nokuhlaba [4], noma ukulolongiswa. Ukulolongiswa kwezindlu noma amandla akho akwazi ukubenza ngokukhaphazile xa usetyenziswa ngesodium isocyanate. Isodium isocyanate inceda ngokuphambili xa ingenqiwe; indlela elincinci lokungenqiwe ngesodium isocyanate lingavunyelwe. Ngakho ke, ukuba sihlaleke siqinisekisane ngeemical enye kunye nokufola kweendlela ezidingekayo. Sifuna ukubona idokotela ngemva kokuba sithetha sikhethwe esebenzisa isodium isocyanate emical yenkululeko kunye nokufinyelela ukuba akukho imicimbi eyahlukileyo.
