Liab silica gel
Cov khoom no yog spherical los yog irregular zoo li tus hais. Nws zoo nkaus li ntshav liab lossis txiv kab ntxwv liab nrog noo noo. Nws cov ntsiab lus tseem ceeb yog silicon dioxide thiab xim hloov nrog cov av sib txawv. Dhau li ntawm kev ua yeeb yam zoo li xiavsilica gel, nws tsis muaj cobalt chloride thiab tsis muaj tshuaj lom, tsis muaj mob.

Alumino silica gel-AN
Cov tsos ntawm aluminiumsilica gelyog xim daj lossis dawb pob tshab nrog cov tshuaj molecular formula mSiO2 • nAl2O3.xH2O. Kev ruaj ntseg tshuaj zoo. Tsis combustion, insoluble nyob rau hauv tej yam hnyav tsuas yog muaj zog puag thiab hydrofluoric acid. Piv nrog cov ntxeem tau zoo silica gel, lub peev xwm adsorption ntawm cov av qis yog qhov 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 nplua ntxeem tau 5 ℃ 0 ℃ siab dua (3 ℃), zoo ntxeem tau silica gel yog li nws yog heev haum rau siv raws li qhov sib txawv kub adsorption thiab sib cais tus neeg sawv cev.

Alumino silica gel - AW
Cov khoom no yog ib hom zoo porous dej resistant aluminosilica gel. Nws feem ntau yog siv los ua cov txheej txheem tiv thaiv zoo ntxeem tau silica gel thiab zoo ntxeem tau txhuas silica gel. Nws tuaj yeem siv tau ib leeg thaum muaj cov ntsiab lus siab ntawm cov dej dawb (kua dej). Yog tias qhov kev khiav hauj lwm muaj cov dej ua kua, qhov qis qis tuaj yeem ua tiav nrog cov khoom no.

Lub hnab me me ntawm desiccant
Silica gel desiccant yog hom tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, ua haujlwm siab nqus cov khoom siv nrog lub peev xwm adsorption.Nws muaj cov khoom siv tshuaj lom neeg ruaj khov thiab tsis muaj kev cuam tshuam nrog cov tshuaj tshwj tsis yog Alkai thiab Hydrofluoric acid, muaj kev nyab xeeb siv nrog cov khoom noj thiab tshuaj. Cov hnab silica gel no tuaj nyob rau hauv ntau qhov ntau thiab tsawg los ntawm 1g txog 1000g - yog li muab kev ua haujlwm zoo rau koj.

Dawb Silica Gel
Silica gel desiccant yog cov khoom siv adsorption muaj zog heev, uas feem ntau yog npaj los ntawm kev ua haujlwm ntawm sodium silicate nrog sulfuric acid, kev laus, kua qaub npuas thiab cov txheej txheem tom qab kho. Silica gel yog cov tshuaj amorphous, thiab nws cov tshuaj formula yog mSiO2. nH2o ua. Nws yog insoluble nyob rau hauv dej thiab tej yam hnyav, uas tsis yog-tshuaj lom thiab tasteless, nrog rau cov tshuaj ruaj khov, thiab tsis hnov mob nrog ib yam khoom tshwj tsis yog lub hauv paus muaj zog thiab hydrofluoric acid. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv ntawm lub cev ntawm silica gel txiav txim siab tias nws muaj cov yam ntxwv uas ntau lwm yam khoom zoo sib xws yog qhov nyuaj los hloov. Silica gel desiccant muaj kev ua haujlwm siab adsorption, zoo thermal stability, ruaj khov khoom, siab mechanical zog, thiab lwm yam.

Blue Silica Gel
Cov khoom muaj cov adsorption thiab noo noo-pov thawj nyhuv ntawm nplua-pored silica gel, uas yog tus cwj pwm nyob rau hauv cov txheej txheem ntawm noo noo nqus, nws muaj peev xwm tig liab doog nrog nce ntawm noo noo nqus, thiab thaum kawg tig lub teeb liab. Nws tuaj yeem tsis tsuas yog qhia cov av noo ntawm ib puag ncig, tab sis kuj pom qhov muag pom seb nws puas yuav tsum tau hloov nrog lub desiccant tshiab. Nws tuaj yeem siv ib leeg los ua tus desiccant, lossis nws tuaj yeem siv ua ke nrog nplua-pored silica gel.
Kev faib tawm: xiav kua nplaum qhia, xim-hloov xiav kua nplaum tau muab faib ua ob hom: spherical hais thiab thaiv cov khoom.

Txiv kab ntxwv Silica Gel
Kev tshawb fawb thiab kev loj hlob ntawm cov khoom no yog raws li xiav gel xim-hloov silica gel, uas yog ib tug txiv kab ntxwv xim-hloov silica gel tau los ntawm impregnating nplua-pored silica gel nrog inorganic ntsev sib tov. ib puag ncig muaj kuab paug. Cov khoom tau dhau los ua ib lub cim tshiab ntawm ib puag ncig cov khoom lag luam nrog nws cov txheej txheem thev naus laus zis thiab kev ua haujlwm zoo adsorption.
Cov khoom no tsuas yog siv rau desiccant thiab qhia txog qib ntawm saturation ntawm desiccant thiab cov txheeb ze av ntawm ntim ntim, precision instruments thiab meters, thiab ya raws-pov thawj ntawm cov ntim dav dav thiab cov twj paj nruag.
Ntxiv nrog rau cov khoom ntawm cov kua nplaum xiav, txiv kab ntxwv kua nplaum kuj muaj qhov zoo ntawm tsis muaj cobalt chloride, tsis muaj tshuaj lom thiab tsis muaj mob. Siv ua ke, nws yog siv los qhia qhov degree ntawm noo noo nqus ntawm lub desiccant, thiaj li txiav txim siab cov av noo ntawm ib puag ncig. Siv dav hauv cov cuab yeej precision, tshuaj, petrochemical, zaub mov, khaub ncaws, tawv, khoom siv hauv tsev thiab lwm yam khoom siv roj.
