tsuas. Tab sis lawv tau sib xyaw ua ke hauv ib qho kev sib tov. Qee zaum tus kheej cov tshuaj ntshiab yog qhov tseem ceeb tshaj qhov sib xyaw. … Yog li, kev sib cais ntawm khoom yog qhov tsim nyog kom tau txais cov tshuaj dawb huv rau lub hom phiaj hauv tsev, kev lag luam thiab kev tshawb fawb ua haujlwm.
Dab tsi yog qhov txiaj ntsig ntawm kev sib cais sib xyaw?
Qee yam yog qhov txiaj ntsig ntawm kev sib cais sib xyaw hauv zej zog
- Yuav haus dej.
- Sib cais ntawm cov tsis-biodegradable rau biodegaradable pov tseg.
- Sib cais sib xyaw hauv cov mining kub tooj liab thiab lwm yam minerals.
- Ntxhais roj nchuav.
- Sib cais xuab zeb los ntawm pob zeb hauv kev tsim kho.
Qhov tseem ceeb ntawm txoj kev sib cais yog dab tsi?
Cov txheej txheem sib cais yog lub ntsiab cog hauv kev tsim khoom zoo ntawm cov txheej txheem tshuaj lom neeg (CPI). Lawv tau siv rau cov haujlwm tseem ceeb xws li tshem tawm cov kab mob ntawm cov khoom siv raw, rov qab thiab ua kom huv ntawm cov khoom tseem ceeb, thiab tshem tawm cov kab mob los ntawm cov dej ntws tawm thiab cua.
Yuav ua li cas cais cov sib tov?
Qee yam ntawm kev sib cais cov tshuaj lossis cov khoom sib xyaw yog:
- Kev xaiv.
- Tshuaj ntsuab.
- Winnowing.
- Siv.
- evaporation.
- Distillation.
- Tshuaj lossis Sedimentation.
- Kev sib cais.
Dab tsi yog qhov tseem ceeb ntawm kev sib xyaw?
Cov khoom sib xyaw yog tsuas yog ib qho tseem ceeb xws li cov khoom, cov khoom sib txuas lossis cov alloysQhov tseeb, huab cua uas koj ua pa tam sim no yog sib xyaw ntawm oxygen, nitrogen thiab qee cov pa roj tsawg! Cov khoom sib xyaw yog siv rau hauv ntau cov txheej txheem, suav nrog kev tsim steel, kev lag luam tshuaj thiab ntau lwm yam.
