Ukuzinza kweekhemikhali zeebhotile zeglasi

Ukuzinza kweekhemikhali zeebhotile zeglasi

Iimveliso zeglasi zihlaselwa ngamanzi, i-acids, iziseko, iityuwa, iigesi kunye nezinye iikhemikhali ngexesha lokusetyenziswa. Ukuxhathisa kweemveliso zeglasi kolu hlaselo kubizwa ngokuba yi-chemical stability.

Ukuzinza kweekhemikhali zeemveliso zebhotile zeglasi kubonakala kakhulu kwibhotile yeglasi echithwa ngamanzi kunye nomoya. Ekuveliseni i-glassware, ezinye iifektri ezincinci ziya kuthi ngamanye amaxesha zinciphise umxholo we-Na2O kwi-chemical composition yeebhotile zeglasi okanye ukunciphisa umxholo we-SiO2 ukunciphisa ukushisa okunyibilikayo kweebhotile zeglasi, ukwenzela ukuba ukuzinza kweekhemikhali zeebhotile zeglasi kunokuncitshiswa.

Iimveliso zebhotile zeglasi ezingazinzanga ngokwekhemikhali ezigcinwe kwindawo efumileyo ixesha elide, ezikhokelela kubunwele obungaphezulu kunye nokulahleka kokubengezela kunye nokubonakala kwebhotile yeglasi. Le nto idla ngokubizwa ngokuba yi "backalkali" kwiifektri. Ngamanye amazwi, iibhotile zeglasi azikwazi ukuzinza kakhulu kwikhemikhali emanzini.

Ingqalelo eyaneleyo kufuneka ihlawulwe kuyo. Musa ukufuna ngokugqithisileyo ukunciphisa ubushushu obunyibilikayo kunye nokwandisa umxholo weNa2O. Enye i-flux kufuneka ifakwe ngokufanelekileyo, okanye ukubunjwa kweekhemikhali kufuneka kulungiswe ukunciphisa ukushisa okunyibilikayo, ngaphandle koko kuya kuzisa iingxaki ezinzulu zomgangatho kwimveliso. Ngamanye amaxesha ngenxa yokuzinza kweekhemikhali ezihluphekileyo, kubonakala ngathi iphelisa "i-backalkali", kodwa xa ithunyelwa kwamanye amazwe anomswakama ophezulu womoya, "i-backalkali" iya kukhokelela kwilahleko enkulu yezoqoqosho. Ngoko ke, ukuzinza kweekhemikhali zeebhotile zeglasi kwimveliso kunokuqonda ngokupheleleyo.
