Liab silica gel
Cov khoom no yog cov khoom me me uas zoo li lub voos xwmfab lossis cov khoom tsis sib xws. Nws zoo li xim av liab lossis txiv kab ntxwv liab nrog rau cov dej noo. Nws cov khoom xyaw tseem ceeb yog silicon dioxide thiab xim hloov pauv nrog cov dej noo sib txawv. Dhau li ntawm qhov ua tau zoo li xiavsilica gel, nws tsis muaj cobalt chloride thiab tsis muaj tshuaj lom, tsis muaj teeb meem.

Alumino silica gel - AN
Cov tsos ntawm txhuassilica gelyog xim daj me ntsis los yog dawb pob tshab nrog cov mis tshuaj molecular mSiO2 • nAl2O3.xH2O. Cov khoom siv tshuaj ruaj khov. Tsis kub hnyiab, tsis yaj hauv cov kuab tshuaj tshwj tsis yog lub hauv paus muaj zog thiab hydrofluoric acid. Piv nrog cov silica gel zoo porous, lub peev xwm adsorption ntawm cov av noo qis zoo sib xws (xws li RH = 10%, RH = 20%), tab sis lub peev xwm adsorption ntawm cov av noo siab (xws li RH = 80%, RH = 90%) yog 6-10% siab dua li ntawm cov silica gel zoo porous, thiab thermal stability (350 ℃) yog 150 ℃ siab dua li cov silica gel zoo porous. Yog li nws yog qhov tsim nyog heev rau siv ua tus neeg sawv cev adsorption thiab sib cais kub sib txawv.

Alumino silica gel – AW
Cov khoom no yog ib hom alumino zoo uas tiv taus dejsilica gelFeem ntau nws yog siv ua txheej tiv thaiv ntawm cov kua silica gel zoo thiab cov kua txhuas silica gel zoo. Nws tuaj yeem siv ib leeg xwb yog tias muaj dej ntau (dej ua kua). Yog tias lub operating system muaj dej ua kua, cov khoom no tuaj yeem ua tiav qhov dej noo qis.

Lub hnab me me ntawm cov tshuaj desiccant
Silica gel desiccant yog ib hom tsis muaj ntxhiab, tsis muaj saj, tsis muaj tshuaj lom, cov khoom siv nqus dej siab nrog lub peev xwm nqus tau zoo. Nws muaj cov khoom siv tshuaj ruaj khov thiab yeej tsis cuam tshuam nrog cov tshuaj tsuas yog Alkai thiab Hydrofluoric acid, muaj kev nyab xeeb siv nrog cov khoom noj thiab tshuaj. Silica gel descicant whisks tawm cov dej noo los tsim ib puag ncig aprotercyive ntawm dryair rau kev khaws cia zoo. Cov hnab silica gel no tuaj yeem muaj ntau qhov ntau thiab tsawg los ntawm 1g txog 1000g - yog li muab kev ua tau zoo tshaj plaws rau koj.

Dawb Silica Gel
Silica gel desiccant yog ib yam khoom siv adsorption uas muaj zog heev, feem ntau yog ua los ntawm kev sib xyaw sodium silicate nrog sulfuric acid, kev laus, kua qaub npuas thiab ntau yam txheej txheem tom qab kho. Silica gel yog ib yam khoom amorphous, thiab nws cov mis tshuaj yog mSiO2. nH2O. Nws tsis yaj hauv dej thiab lwm yam kuab tshuaj, tsis muaj tshuaj lom thiab tsis qab, nrog cov khoom siv tshuaj ruaj khov, thiab tsis sib xyaw nrog lwm yam khoom tsuas yog lub hauv paus muaj zog thiab hydrofluoric acid. Cov tshuaj lom neeg thiab cov qauv ntawm silica gel txiav txim siab tias nws muaj cov yam ntxwv uas ntau lwm yam khoom zoo sib xws nyuaj rau hloov. Silica gel desiccant muaj kev ua tau zoo adsorption, zoo thermal stability, ruaj khov tshuaj lom neeg, muaj zog kho tshuab siab, thiab lwm yam.

Xiav Silica Gel
Cov khoom muaj cov nyhuv adsorption thiab noo noo ntawm cov silica gel zoo-pored, uas yog tus cwj pwm hauv qhov tias thaum lub sijhawm nqus dej noo, nws tuaj yeem tig xim av nrog kev nce ntawm kev nqus dej noo, thiab thaum kawg tig lub teeb liab. Nws tsis tsuas yog qhia txog qhov av noo ntawm ib puag ncig, tab sis kuj pom tseeb tias nws puas xav tau hloov nrog lub desiccant tshiab. Nws tuaj yeem siv ib leeg ua desiccant, lossis nws tuaj yeem siv ua ke nrog cov silica gel zoo-pored.
Kev faib tawm: qhov qhia txog kua nplaum xiav, kua nplaum xiav hloov xim tau muab faib ua ob hom: cov khoom me me thiab cov khoom thaiv.

Txiv kab ntxwv Silica Gel
Kev tshawb fawb thiab kev txhim kho ntawm cov khoom no yog raws li xiav gel xim hloov pauv silica gel, uas yog xim txiv kab ntxwv hloov pauv silica gel tau los ntawm impregnating zoo-pored silica gel nrog inorganic ntsev sib tov. ib puag ncig ua qias tuaj. Cov khoom tau dhau los ua ib tiam tshiab ntawm cov khoom lag luam zoo rau ib puag ncig nrog nws cov xwm txheej thev naus laus zis qub thiab kev ua tau zoo adsorption.
Cov khoom no feem ntau yog siv rau desiccant thiab qhia txog qib ntawm kev saturation ntawm desiccant thiab qhov sib piv ntawm cov av noo ntawm cov ntim khoom kaw, cov cuab yeej precision thiab meters, thiab cov dej noo-pov thawj ntawm cov ntim khoom dav dav thiab cov cuab yeej.
Ntxiv rau cov khoom ntawm cov kua nplaum xiav, cov kua nplaum txiv kab ntxwv kuj muaj qhov zoo ntawm tsis muaj cobalt chloride, tsis muaj tshuaj lom thiab tsis ua rau muaj kev phom sij. Siv ua ke, nws yog siv los qhia qib ntawm kev nqus dej noo ntawm cov desiccant, yog li txiav txim siab qhov av noo ntawm ib puag ncig. Siv dav hauv cov cuab yeej precision, tshuaj, petrochemical, khoom noj, khaub ncaws, tawv, khoom siv hauv tsev thiab lwm yam roj kev lag luam.
