Hauj lwm lawm
Ntawm qhov nruab nrab mus rau lub tsev loj, cov neeg yuav khoom tuaj yeem khaws cov tshuaj ntxuav tes, yuav ib lub raj mis ntawm cov tshuaj aspirin thiab saib cov xov xwm tshiab ntawm cov ntawv xov xwm thiab cov ntawv xov xwm. Thaum xub thawj siab ib muag, nws yuav tsis zoo li cov khoom no muaj ntau yam sib xws. Txawm li cas los xij, rau txhua tus ntawm lawv, caustic soda plays lub luag haujlwm tseem ceeb hauv lawv cov npe khoom lossis cov txheej txheem tsim khoom.
Dab tsi yog caustic soda?
Nws yog chemical compound sodium hydroxide (NaOH). Cov tshuaj no yog alkali - ib hom ntawm lub hauv paus uas muaj peev xwm neutralize acids thiab soluble nyob rau hauv dej. Niaj hnub no caustic soda tuaj yeem tsim nyob rau hauv daim ntawv ntawm pellets, flakes, hmoov, kev daws teeb meem thiab lwm yam.
Dab tsi yog caustic soda siv rau?
Nws tau dhau los ua ib qho khoom siv hauv kev tsim khoom ntawm ntau yam khoom siv niaj hnub. Feem ntau hu ua lye, nws tau siv los ua xab npum rau ntau pua xyoo, thiab nws lub peev xwm los yaj cov roj ua rau nws muaj cov khoom xyaw hauv qhov cub ntxuav thiab cov khoom siv los tshem tawm cov dej. Sodium hydroxide kuj tseem ua lub luag haujlwm tseem ceeb hauv kev ua cov ntoo ntoo los tsim cov ntawv thiab cov thawv ntawv, uas tau dhau los ua qhov tseem ceeb ntxiv rau lub sijhawm thoob ntiaj teb COVID{0}} muaj thoob qhov txhia chaw vim cov khoom siv kho mob raug xa mus ntev. Cov tshuaj lom neeg kuj tseem siv los rhuav tshem cov pob zeb sedimentary uas txhuas tau muab rho tawm los. Cov ntxhia ces mus siv rau hauv ntau yam khoom xws li cov khoom siv, tsheb thiab cov khoom siv xws li cov ntim khoom noj thiab cov kaus poom dej qab zib.Cov khoom siv dej ntau yam, sodium hydroxide feem ntau siv los tswj kev nyab xeeb thiab huv ntawm cov pas dej los ntawm kev tshem tawm cov teeb meem. hlau xws li txhuas thiab tooj liab. Raws li lub hauv paus, sodium hydroxide txo qis acidity, tswj dej pH. Tsis tas li ntawd, lub compound tuaj yeem siv los tsim sodium hypochlorite, uas ntxiv cov tshuaj tua kab mob hauv dej. Ib qho kev npaj txhij txog siv rau caustic soda yog nyob rau hauv kev tsim cov tshuaj xws li cov ntshav thinners thiab tshuaj cholesterol.
Kev sib koom ua ke ntawm cov txheej txheem tsim tshuaj chlorine, caustic soda tau siv ntau xyoo los tsim cov khoom uas txhim kho peb lub neej txhua hnub.
