Qhov sib txawv tseem ceeb ntawm desiccant thiab deliquescent yog lub sij hawm desiccant piav txog cov khoom uas yog hygroscopic, tab sis lub sij hawm deliquescent yog hais txog lub peev xwm nqus dej noo thiab ua kua.
Lub sij hawm desiccant yog hais txog ib yam khoom uas siv tau los tshem tawm cov dej noo ntawm ib puag ncig. Nws yog siv los ua ib lub npe rau ib qho kev sib txuas. Lo lus deliquescent piav txog ib yam khoom ntawm ib yam khoom, thiab nws yog siv raws li ib tug adjective los piav txog ib yam khoom.
Dab tsi yog Desiccant?
A desiccant yog ib yam khoom uas tuaj yeem nqus dej vapor los ntawm ib puag ncig sab nraud. Thiab, lo lus no yog siv los xa mus rau "cov khoom siv hygroscopic". Hygroscopic tshuaj yog cov khoom uas muaj peev xwm nqus tau los yog nqus dej los ntawm nws ib puag ncig. Thaum cov dej vapor absorbed los ntawm hygroscopic tshuaj, cov dej molecules raug coj mus rau hauv qhov chaw ntawm cov qauv siv lead ua. Nws ua rau lub ntim ntawm cov khoom nce. Hygroscopy tuaj yeem ua rau muaj kev hloov pauv hauv lub cev ntawm cov khoom hygroscopic; cov khoom xws li xim, kub taw tes, viscosity, thiab lwm yam.
Daim duab 01: Zinc Chloride yog ib lub tshuab nqus tsev
Feem ntau cov piv txwv ntawm hygroscopic tshuaj muaj xws li ntsev. Qee qhov piv txwv yog Zinc chloride (ZnCl 2), sodium chloride (NaCl) thiab sodium hydroxide (NaOH). Kuj tseem muaj lwm yam tshuaj uas peb paub tias yog hygroscopic. Cov tshuaj no muaj xws li zib ntab, silica gel, germinating noob, thiab lwm yam.
Dab tsi yog Deliquescent?
Lo lus deliquescent yog hais txog lub peev xwm ntawm cov khoom nqus dej noo los ntawm ib puag ncig thiab yaj nws tus kheej. Yog li ntawd, cov khoom deliquesescent yog cov teeb meem uas tuaj yeem yaj los ntawm kev nqus dej vapor. Lub resulting tov yog ib tug aqueous tov. Thiab, txoj kev no yog hu ua deliquescence. Cov tshuaj deliquescent no muaj kev sib raug zoo rau dej.
Cov huab cua muaj 0-4% ntawm cov pa dej, nyob ntawm qhov chaw thiab sijhawm ntawm hnub. Txij li thaum muaj ntau lwm yam gases thiab vapors nyob rau hauv cov huab cua, dej vapor muaj ib nrab siab. Deliquescence tshwm sim thaum lub vapor siab ntawm cov tshuaj uas yuav tsim tsawg tshaj li ib nrab siab ntawm cov dej vapor nyob rau hauv cov huab cua.
Daim duab 02: Calcium Chloride yog ib qho khoom noj khoom haus zoo
qhov chaw ntub dej yog qhov muaj zog heev nrog dej vapor. Yog li ntawd, cov tshuaj deliquescent tuaj yeem yooj yim nkag mus rau deliquescence thiab tsim cov kev daws teeb meem los ntawm kev nqus cov dej vapor ntau thaum lawv muab tso rau hauv qhov chaw ntub dej.
Feem ntau cov piv txwv ntawm cov khoom tsis zoo muaj xws li qee cov ntsev; Piv txwv li, sodium hydroxide, potassium hydroxide, ammonium chloride, sodium nitrate, calcium chloride, thiab lwm yam. Cov tshuaj no tuaj yeem siv ua desiccants. Thaum cov dej vapor hauv lub thawv yuav tsum tau muab tshem tawm kom tsis txhob muaj tshuaj lom neeg, cov tshuaj no tuaj yeem khaws cia rau hauv lub thawv. Tom qab ntawd, cov khoom tsis zoo yuav nqus dej ntau thiab tiv thaiv kev cuam tshuam los ntawm dej vapor.
