Umbuyiselwano wocarboxyl we-isocyanate ewayelekile kumazwana akho apha xa kunjalo lento alunemfanelo kakhulu ekuziphindaphindeni. Lokhu kukholelwa ukufunda nge-umbuyiselwano wocarboxyl we-isocyanate kungcono, sizoba sihlale kakhulu kunye nokusetshenziswa kwenye into. Izibophelelo zethu kwindawo yokugcina nokusebenza kuya kuthola ukuthi siyisebenzisa ngempumelelo.
I-Carbonyl isocyanate yinto yokuchoba okanye yokulayishwa, eyenza ukuba lizama ukuhlola ngokubanzi ngezinye izinto. Leli lihlanu lezi zintathu: umthombo wase-carbonyl (umthombo we-carbon double-bonded kwi-oxygen) kunye no-isocyanate group (eyenzeka yi-nitrogen kunye ne-carbon). U-Carbonyl isocyanate ungenani lwe-chemical formula (CO)₂(NCO)₂. Yintlanti engaqondiniyo, enza ukuba ungabona ngaphakathi kwesiqephu. Ukuba i-Carbonyl isocyanate alinganakho kungqinisekileyo xa lihlola ngesi-water, amaloholi, kunye ne-amines, ezintathu zizinto ezilayishwa kakhulu ezixhaswe kumgangatho.
Isobhayisayensi kwekhaboni inqamathelwa ngeminye eminingi yezinto ezazisebenzeka (nazo zibonakalisekile) ngomlilo wethu. Zizikhululeka amanye amagama, iimedi, iiplastiki nokumlinganiswa okusebenza kwamafarmi. Ngoba isobhayisayensi kwekhaboni ukhupha kwisebele sokuqhathanisa ngezinto eziphakathi zakhe, uzifuna lokugcina ngokukhangelwa kakhulu izinto ezidingekayo. Ukusetyenziswa kwe-resins esetshonalanga - imininingwane engaba kwiimbhenge nezintsha. I-resins yesayensi selandelayo esebenza ukuba lezinto zithole ngaphandle kokubhalela kunye nokuhlola kakhulu. Futhi, isobhayisayensi kwekhaboni usetyenziswa ngokuxhasa lokuhamba lwezityalo olunqumelela amadoda amahhadi aphantsi nokuvula umhlaba wendaweni yokugcina nokufundiswa.
Ukuba kuhle kwenzelelo yokusetshenziswa kwe-sobhayisayensi kwekhaboni. Uma ungakusetshenziswa ngokuphi indlela ezidingekayo, uSANYING umdinga we-polyol kunye ne-isocyanate umthiwilo ophathelene ukuze aluhlale kakhulu. Ungayiphumelela umzimba wethu, amagcebi nezinye izilungu zethu ukhona esebenzisa ngaphandle kokuthi uzifunyenwe. Ukufakwa kwezindlu ezikhelekileyo ze-carbonyl isocyanate ungabulala amandla eziphumaphi kwisebe sasendaweni, njengokubhekiselela kwezinye izilungu lokugcina ukusuka kwindawo yokusebenza. Ngokwesiphiwo lesithathu, kufuneka uvake amagogli neziglove ngenxa yokuqinisekiswa ukusebenza nge-chemical. Lento ithathe imfanelo yokuthi singafuna ukuprotekisela phakathi konke into eyenziwayo ukuba asibulale kwisebe sakho.
Izilungiselelo zokuthutha zaziqinisekileyo ukuba uhlola kweCarbonyl isocyanate ungaphindaphinda ukukhetha amandla esincane kwisebe sako. Uma umntu ulula lokhu, ungene ngezintsha ezikhulu ngokubanzi nokuhlaba kuhlonipha ukulula. Izintsha ezikhulu zakho zakwazi ukuxhasa imibiko yezinto eziphumaphi. Ngokugcina, ukusuka kakhulu kakhulu kunye noCarbonyl isocyanate akufuneki ukuphuma izigoduso zemibuzo yokusebenza, phakathi kwesonto nokulula, okungayiqhuba ukulula. Ndizobhekela ukuya kwindaweni engaphantsi kwalokhu olungaxoxwa kakhulu kunye nokuthola amanxaso amatshabaliso ngokubanzi neSANYING polyol isocyanate .
Ukushintsha okubekwa phosgene kunye namine inikeza iCarbonyl isocyanate. Lento lokushintsha linikeza iCarbonyl isocyanate njengeumphoyiso. Carbonyl SANYING polyol kunye no-isocyanate ungayibuyiswa kwiqhutywa elinamandla yeezilimi zokubuyiselwa ngaphandle kokuthiwe. Amaxhobo, amabili omphumeleyo aphakathi komphendula izinto ezimbini, ziyinqanawa yokugcina okulandelwayo. Ngakwesoku, umbuyiselwano wocarboxyl we-isocyanate ungene ukusetyenziswa kuhlanganiswa kwezinto ezikhoyo ezininzi ezithetha ngezinye iindlela ezifaneleyo nokuphela nokufundziswa e.g. ukukhangela imifanekiso yakhe yi-drugs okanye ukuba kuvela isicwangciso sasintshabele.
