Ukukhethwa kwamabhodlela engilazi kuthinta kakhulu ikhwalithi kanye nokunambitheka kotshwala. Ukwehluka kokwakheka kwamakhemikhali kwamabhodlela engilazi ahlukene kungaholela ekuqhekekeni kwezingxenye ezithile otshwaleni, okungenzeka kushintshe ukunambitheka kwalo kanye nekhwalithi yalo iyonke. Ukuqonda la mathonya kubalulekile kubakhiqizi kanye nabathengi ngokufanayo.
Ukwakheka Kwamakhemikhali Nokuxhumana
Izinhlobo ezahlukene zengilazi zibonisa izakhiwo zamakhemikhali ezahlukahlukene. Amabhodlela asetshenziswa kakhulu embonini yotshwala ngokuvamile acacile noma akhanya, kanti ingilazi ekhanyayo ekhanyayo ithola ukuthandwa. Lolu hlobo lwengilazi luhlanganisa izithasiselo ezifana ne-fluoride phosphate, ezidala okusanhlamvu okuncane okusabalalisa ukukhanya, okuthuthukisa ukubukeka kwebhodlela.
Kodwa-ke, uma utshwala bugcinwa kula mabhodlela, kungenzeka ukusebenzisana kwamakhemikhali. Ucwaningo lubonisa ukuthi amanzi akhululekile ewayinini angasabela nezingxenye ezisengilazini. Isibonelo, amanani amancane e-potassium (K+) angathuthukisa ukunambitheka kweziphuzo ezindala, kuyilapho i-sodium (Na+) ingathinta kabi iphunga nokucaca kwewayini. Ngaphezu kwalokho, ukuba khona kwe-aluminium (Al3+) kungaholela ekuwohlokeni kwekhwalithi, okubangela ukuthi utshwala bube lula futhi buqine kakhulu.
Ukukhetha Amabhodlela Engilazi Afanele
Ukuze kuncishiswe le miphumela, kubalulekile ukukhetha amabhodlela engilazi ngokucophelela. Ukugwema amabhodlela aqukethe izinsimbi ezisindayo eziyingozi kubalulekile ukuvikela impilo yabathengi. Ukukhetha amabhodlela anokuqukethwe okuphezulu kwe-silica (SiO2) kanye nokuqukethwe okuphansi kwe-sodium oxide (Na2O) kungasiza ekugcineni ubuqotho botshwala.
Ukwelapha amabhodlela ngamanzi ngaphambi kokuwagcwalisa kunganciphisa ngempumelelo ithonya lokwakheka kwebhodlela ekhwalithini yotshwala. Lo mkhuba unganciphisa ingozi yokuthi izinto ezingafuneki zincibilike otshwaleni.
Isiphetho
Ngamafuphi, uhlobo lwebhodlela lengilazi elisetshenziselwa utshwala lungathinta kakhulu ikhwalithi yesiphuzo kanye nephrofayili yokunambitheka kwaso. Ngokuqonda ukusebenzisana kwamakhemikhali nokukhetha ngokucophelela ukupakishwa kwengilazi okufanele, abakhiqizi botshwala bangaqinisekisa ukuthi imikhiqizo yabo ihlala ihlanzekile futhi ikhanga abathengi. Lokhu kunakwa emininingwaneni akugcini nje ngokuthuthukisa ulwazi lokuphuza lonke kodwa futhi kuvikela impilo yomthengi.
