Cov kav dej yog cov khoom siv "lifeline" rau kev tsim khoom thiab kev txhim kho cov roj thiab cov roj av hauv hiav txwv thiab cov peev txheej minerals. Cov thev naus laus zis kav dej khov kho tau loj hlob tuaj, tab sis kev txwv hauv kev khoov tau, kev tiv thaiv xeb, kev teeb tsa thiab kev tso ceev tau ua rau nws cov nqi tag nrho nce ntxiv. Cov xwm txheej hauv qab no yuav tshwm sim hauv kev siv cov kav dej khov kho:
Tsis muaj kev ywj pheej: Cov kav dej khov kho, vim lawv cov duab ruaj khov, tsis muaj peev xwm khoov lossis ncab, thiab yog li ua tsis tau zoo rau cov zog sab nraud xws li kev hloov pauv hauv av, kev hloov pauv kub, lossis av qeeg, tnws tej zaum yuav ua rau cov yeeb nkab tawg lossis puas.
Kev cuam tshuam rau kev ntxhov siab thiab kev qaug zog: Thaum cov kav dej khov kho raug rau cov khoom hnyav sab nraud, qhov tsis muaj peev xwm nqus lossis faib kev ntxhov siab yuav ua rau muaj kev ntxhov siab ntau ntxiv hauvtseebthaj chaw. Qhov no ua rau cov yeeb nkab yooj yim rau kev ua haujlwm tsis zoo, tshwj xeeb tshaj yog tias nws raug kev co lossis kev poob siab ntau zaus.
xeb: Kev xeb yog ib qho ua rau muaj kev puas tsuaj hauv cov kav dej khov khocov kab, tshwj xeeb tshaj yog metal cov kav dej. Dhau sij hawm, raug dej noo, tshuaj lom neeg thiab lwm yam tshuaj corrosive tuaj yeem ua raucov kav dejkom puas tsuaj, ua rau muaj kev xau thiab kev ua haujlwm tsis muaj zog.
Ua ib qho kev daws teeb meem tshiab, hloov tau yooj yimcov kav dejhaveTus nqi thov tseem ceeb hauv kev tsim khoom thiab kev txhim kho cov roj thiab cov roj av hauv hiav txwv thiab cov peev txheej hauv av. Nws cov txiaj ntsig xws li kev khoov tau, tiv thaiv xeb, kev teeb tsa thiab kev tso saitshem tawmcov kev txwv ntawm cov kav hlau ib txwm muaj, txo cov nqi tag nrho, thiab muab kev daws teeb meem zoo dua thiab txhim khu kev qha. Nrog rau kev txhim kho tas mus li ntawm thev naus laus zis, hloov pauv tau yooj yimcov yeeb nkabs ua lub luag haujlwm tseem ceeb hauv kev lag luam kev txhim kho cov peev txheej hauv hiav txwv.
Qhov zoo ntawm cov hoses yooj ywm:
