I-Dichloromethane: Isinyibilikisi Esinezinto Ezininzi Esijongene Nokuphononongwa Okungakumbi

I-Dichloromethane (DCM), ikhompawundi yekhemikhali enefomyula i-CH₂Cl₂, ihlala isinyibilikisi esisetyenziswa kakhulu kumashishini amaninzi ngenxa yeempawu zayo ezibalaseleyo. Olu lwelo lungenambala, oluguquguqukayo olunevumba elimnandi nelithambileyo luxatyiswa ngokusebenza kwalo okuphezulu ekunyibilikiseni uluhlu olubanzi lweekhompawundi ze-organic, nto leyo eyenza ukuba ibe sisithako esiqhelekileyo kwii-paint strippers, degreasers, kunye ne-aerosol formulations. Ngaphezu koko, indima yalo njengearhente yokucubungula ekwenziweni kwamayeza kunye neemveliso zokutya, ezifana nekofu engena-caffeine, igxininisa ixabiso layo elibalulekileyo kwimizi-mveliso.

Nangona kunjalo, ukusetyenziswa ngokubanzi kwe-dichloromethane kuhamba neenkxalabo ezinkulu zempilo kunye nokusingqongileyo. Ukuvezwa kumphunga we-DCM kunokubangela iingozi ezinkulu kwimpilo yabantu, kubandakanya nomonakalo onokubakho kwinkqubo yemithambo-luvo ephakathi. Kwizinga eliphezulu, kuyaziwa ukuba kubangela isiyezi, isicaphucaphu, kwaye, kwiimeko ezinzima, kunokubulala. Ngenxa yoko, imigaqo yokhuseleko engqongqo egxininisa ekuphefumleni umoya okwaneleyo kunye nezixhobo zokuzikhusela zomntu iyimfuneko kubaphathi.

Iiarhente zokusingqongileyo nazo zigxile kwimpembelelo ye-dichloromethane. Ichazwa njengeVolatile Organic Compound (VOC), inegalelo kungcoliseko lomoya kwaye inokwenza i-ozone esezantsi. Ukuhlala kwayo emoyeni, nangona iphakathi, kufuna ulawulo olucokisekileyo lokukhululwa kwayo kunye nokulahla kwayo.

Ikamva le-dichloromethane liphawulwa kukukhuthazwa kobuchule bokuvelisa izinto ezintsha. Ukukhangela ezinye iindlela ezikhuselekileyo nezizinzileyo kuyakhawuleza, kuqhutywa ziingcinezelo zomthetho kunye notshintsho lwehlabathi oluya kwikhemistri eluhlaza. Nangona i-dichloromethane isaqhubeka nokuba sisixhobo esibalulekileyo kwizicelo ezininzi, ukusetyenziswa kwayo ixesha elide kuvavanywa ngokunzulu, kulungelelaniswa ukusebenza kwayo okungenakuthelekiswa nanto kunye nokubaluleka kweendawo zokusebenza ezikhuselekileyo kunye nendawo ephilileyo.
