Cov tshuaj feem ntau siv los ua cov dej ua kom lub cev qhuav dej muaj xws li concentrated phosphoric acid, concentrated sulfuric acid , kub ceramic thiab kub aluminium oxide.
Yog li ntawd, dab tsi yog qhov zoo tshaj plaws dehydrating tus neeg sawv cev?
Nitric thiab perchloric acids raug muag ntawm 70% aqueous, yog li feem ntau ntawm lawv lub peev xwm dehydrating twb tau noj, thaum sulfuric acid yog muag li 98%. Ntawm 98% concentration, nitric thiab perchloric acids yuav ua tau zoo heev dehydrating agents, tab sis cov no kuj muaj zog oxidizers, tsis ruaj khov, thiab lwm yam.
Tsis tas li ntawd, leej twg ntawm cov hauv qab no yog tus neeg ua kom lub cev qhuav dej? Sulfuric acid , concentrated phosphoric acid, kub aluminium oxide, thiab kub ceramic yog cov neeg ua kom lub cev qhuav dej hauv cov tshuaj no.
Tib neeg kuj nug, dab tsi yog tus neeg ua kom lub cev qhuav dej nrog piv txwv?
Dehydrating agent yog ib tus neeg sawv cev uas absorbs dej. Nws yog tam sim no nyob rau hauv lub cev qhuav dej txheej txheem. Qhov ntau cov neeg ua kom lub cev qhuav dej siv nyob rau hauv cov organic synthesis yog sulfuric acid, concentrated phosphoric acid, kub ceramics, kub aluminium oxide.
Dab tsi yog cov yam ntxwv ntawm tus neeg saib xyuas lub cev kom zoo?
Cov yam ntxwv ntawm ib qho zoo tagnrho dehydrating tov
- Lub cev qhuav dej sai sai yam tsis muaj qhov cuam tshuam loj heev los yog distortion ntawm. cov ntaub so ntswg.
- Tsis evaporate ceev heev.
- Lub cev qhuav dej txawm tias cov ntaub so ntswg rog.
- Tsis txhob tawv nqaij ntau dhau.
- Tsis tshem cov stains.
- Tsis lom rau lub cev.
- Tsis yog hluav taws kub.
