Yuav Ua Li Cas Niaj Hnub No Antifreeze Fluids Txhim Kho Cov Khoom Siv Mining

Kev lag luam mining kev thawb rau xyoo- kev tsim khoom ib puag ncig tau ua rau muaj kev nce qib tseem ceeb hauv hydraulic kua tshuab. Niaj hnub no cov tshuaj tiv thaiv kab mob ua rau ntau dua li tiv thaiv kev khov - lawv nquag txhim kho cov tshuab ua haujlwm hauv cov xwm txheej hnyav.

Niaj hnub nimno tshuaj tiv thaiv kab mob ua kom pom kev viscosity thoob plaws qhov kub tsis tau dhau los (-50℃txog 120 degree). Qhov no yog ua tiav los ntawm:

• Synthetic base oils nrog cov qauv molecular ruaj khov

• Advanced viscosity index improvers

• Kub- teb cov pob khoom ntxiv

Mines hauv Canada lub Northwest Territories tshaj tawm 40% tsawg dua hydraulic tsis ua haujlwm thaum lub caij ntuj no tom qab hloov mus rau cov kua dej no. Chilean tooj liab ua haujlwm siv lawv nyob rau hauv siab - qhov chaw siab tshaj pom 25% lub twj tso kua mis ntev dua.

1. Txias -Pib Kev Ntseeg
Tam sim ntawd ntws ntawm sub- xoom kub tshem tawm sov- nce qeeb
Txo cov ntsiab lus kev ntxhov siab thaum lub sijhawm pib tseem ceeb

2. Kev Siv Hluav Taws Xob
Tsawg viscosity nyob rau hauv txias txias yuav txo hwj chim xav tau
Cov ntaub ntawv 8-12% kev txuag roj hauv cov khoom siv diesel

3. Cov khoom tiv thaiv
Multi- txheej tiv thaiv- siv tshuab tiv thaiv:

• Hlau-rau-hlau kov

• Corrosion los ntawm condensation

• Ua kua qaub

Tshiab biodegradable formulations raws li nruj mining sustainability qauv thaum xa khoom sib npaug. Cov yam ntxwv tseem ceeb muaj xws li:

• Kev tawg sai sai yog tias tso tawm

• Tsis yog- cov pob khoom muaj kuab lom

• Cov kua dej rov ua dua tshiab

Kev ua tau zoo yuav tsum muaj:

• Ua kom tiav qhov dej ntws tawm ua ntej hloov dua siab tshiab

• Kev tshuaj xyuas kua dej tsis tu ncua (txhua 500 teev ua haujlwm)

• Tshem tawm cov kua dej qub qub kom raug

Cov ntaub ntawv nyiaj txiag yog yuam. Thaum cov tshuaj tiv thaiv kab mob zoo tshaj plaws raug nqi 20-30% ntau dua pib, lawv feem ntau xa:

• 30-40% ncua kev pab cuam ntev dua

• 15-20% txo tus nqi tu

• 5-7% nce cov khoom siv

Raws li kev lag luam mining nthuav dav mus rau ntau qhov chaw huab cua, cov kua dej siab tshaj no tau dhau los ua cov haujlwm tsim nyog es tsis yog kev xaiv hloov kho dua tshiab. Lawv lub peev xwm los tiv thaiv cov cuab yeej kim thaum txhim kho cov khoom tsim tau ua rau lawv muaj peev xwm ntse rau txhua qhov kev lag luam ntsib teeb meem kub.

Cov tiam tom ntej ntawm cov kua tshuaj tiv thaiv kab mob ntse, tam sim no nyob rau hauv txoj kev loj hlob, yuav suav nrog cov xwm txheej - saib xyuas kev muaj peev xwm thiab tus kheej - kho cov khoom viscosity - ntxiv kev hloov pauv huab cua txias - huab cua mining.
