Thawj hom ntawm silica gel desiccant yog silica dioxide, tsim los ntawm cov tshuaj tiv thaiv ntawm cov sodium silicate thiab sulfuric acid. Cov txheej txheem no tsim ib tus qauv sab hauv tsim muaj cov microcrystals heev. Lub Nanoscale Pa hauv cov qauv no tau tsim muaj zog Capillary Adsorary Adsoratment rog, tso cai rau kev ntes ntawm cov dej lwg me me ntawm huab cua. Nyob rau hauv cov qauv ntawm cov qauv ntawm 25℃thiab 80% tus txheeb ze nqus av, nws noo noo nqus muaj peev xwm tuaj yeem ncav cuag 30% rau 40% ntawm nws tus kheej qhov hnyav. Qhov tseem ceeb, silica gel ua haujlwm los ntawm lub cev adsorption, tsis yog tshuaj lom neeg. Qhov kev sib txawv no txhais tau tias nws tsis yaj nyob rau hauv kev nqus dej noo (cov tawv nqaij), lossis tso cov khoom ua kom muaj kev phom sij, ua rau muaj kev nyab xeeb profile. Cov txheej txheem Adsorption tshwm sim hauv peb theem: pib ua tiav saum npoo av, ua raws li kev npau taws, thiab thaum kawg capillary uas muaj cov dej nyob hauv cov hws hauv lub pores. Cov txheej txheem no yog cov rov qab tag nrho. Thaum noo noo, cov dej nqus tau tuaj yeem muab tshem tawm los ntawm kev thov cua sov, uas tau rov tsim dua cov desiccant rau kev siv tsheb kauj vab.
Kev faib tawm ntawm Silica Gel Desiccants rau cov ntawv thov tsom
Silica Gel Desiccants yog catororized raws li pore loj, xim {- ntsuas cov khoom, feem ntau yog ua rau plaub hom. Zoo -}}}}}}}}}}}}}}}}}}} Zoo nkaus li dawb, translucent, iav- zoo li pellets. Nws muaj lub siab ntom ntom ntom thiab zoo nyob rau hauv kev nqus noo noo nyob rau hauv qis rau nruab nrab noo noo, feem ntau ntawm 20% thiab 50% txheeb ze cov av noo. Nws cov kev siv cov kev siv suav nrog kev tiv thaiv hluav taws xob sib xws los tiv thaiv cov khoom lag luam uas muaj peev xwm tiv thaiv cov khoom siv los tswj cov khoom siv noo noo. Ntxhoo -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} ishregular lossis spherical granules nrog qhov loj dua. Nws ua kom pom tseeb kev ua tau zoo hauv qhov siab tshaj plaws hauv siab, ua rau muaj cov khoom siv noo noo, thiab cov khoom siv nqus dej ua ke rau kev ua si ntxiv rau hauv lwm cov khoom lag luam silica gel. Xiav xiav silica gel desiccant yog imprognated nrog cobalt chloride raws li qhov ntsuas. Nws muab cov cim qhia meej los ntawm kev hloov xim los ntawm xiav mus rau liab liab thaum noo noo surmation. Qhov no ua rau nws haum rau cov av noo kev soj ntsuam zoo li cov iav lo ntsiab muag zoo li cov khoom siv hluav taws xob zoo li cov khoom siv hluav taws xob zoo nkauj, thiab rau muab cov khoom siv hluav taws xob thaum ntxov kom sai hloov chaw. Ib qho tseem ceeb rau kev nyab xeeb yog tias cobalt chloride yog tshuaj lom, yog li hom no yuav tsum tsis txhob siv rau qhov twg nws yuav tiv tauj cov zaub mov lossis chaw ua tshuaj. Tsis - Cobalt xim {{} Hloov silica gel hloov silica gel- kev hloov pauv. Nws feem ntau hloov los ntawm txiv kab ntxwv maub ntsuab thaum saturated. Nws txoj kev nyab xeeb profile ua rau nws tsim nyog rau cov zaub mov thiab ntim khoom siv, txhawm rau tiv thaiv cov cuab yeej siv tshuaj kho mob ntim, suav nrog kev cog lus.
Xaiv cov khoom ntim ntim
Cov khoom ntim ntim yog qhov tseem ceeb tshaj plaws uas txiav txim siab cov kev ua tau zoo thiab haum cov kev ua tau zoo thiab ua kom haum rau ib daim ntawv thov tshwj xeeb, ntsuas nrog cov khoom lag luam. Tyvek yog qhov siab - Kev ua tau zoo cov khoom siv, muaj zog ua tsis tau zoo, nrog kev lees paub thoob ntiaj teb; Nws yog qhov kev xaiv uas xav tau rau cov khoom siv hluav taws xob rhiab thiab cov twj paj nruag. Spunlace tsis- Woven npuag yog muaj nuj nqis rau nws cov khoom muag, thiab cov khoom lag luam qis, thiab cov khoom lag luam zoo ib yam li cov khaub ncaws thiab khau. OPP zaj duab xis muaj transparency, tso cai rau kev pom kev pom ntawm cov desiccant, thiab muaj lub zog zoo tab sis yuav tsum tau microrations kom tso dej noo; Nws yog feem ntau siv nyob rau hauv khw muag khoom lossis zaub ntim rau cov khoom xws li khoom plig thiab khoom siv tes ua. Composite daim ntawv yog qhov kev xaiv nyiaj txiag uas muaj cov ntawv luam tawm zoo thiab cua sov {9} Kev muaj kev tiv thaiv dav dav noo noo. Lined tsis- woven composite ntawv muaj cov roj ua kom zoo xws li thoob ntiaj teb shipping thiab ntev} lub sij hawm cia. Cov txheej txheem xaiv yuav tsum ua tib zoo xav kom noo noo vapor kis tawm tsam tus kheej hmoov av, tshwj xeeb tshaj yog ntim cov khoom noj uas yuav tsum tau ua.
Kev tsim cov qauv rau tus nqi -}} Siv tau zoo
Qhov tseem ceeb nyiaj txiag kom zoo dua ntawm silica gel desiccants yog lawv lub peev xwm dhau 30 mus, los ntawm kev tshem cov dej noo zuj zus los ntawm cua sov. Ua raws li kev ua haujlwm tsim kho yog qhov tseem ceeb los tswj kev ua tau zoo. Rau kev hloov pauv silica gel uas muaj cov dej adsorbed, ntsuas kub yog qhov ntsuas. Txheem Silica GEL feem ntau yuav tiv taus kub ntawm 120 kawm ntawv, thaum muaj kev hloov pauv qis dua 120 txog 120℃los tiv thaiv kev puas tsuaj rau qhov ntsuas. Qhov kub tshaj tshaj 200℃yuav tsum tau zam raws li lawv tuaj yeem ua kom tiav ntawm cov qauv porous. Cov txheej txheem txheem cuam tshuam nrog cov enticcant aintcant tusyees ntawm ib lub tais ua kom sov rau nws cov xim cua sov lossis cov granules ua kom qhuav thiab dawb} kev ntws. Cov kev ceeb toom tseem ceeb muaj maj mam nce qhov kub kom tiv thaiv cov hlaws thiab sining cov khoom siv tau los tshem tawm cov hmoov av zoo thiab ua kom pom cov pob zeb zoo nkauj. Rau silica gel uas muaj adsorbed organic vapors, yuav tsum muaj cov hau kev sib luag. Txoj kev cais tawm no cuam tshuam nrog siab-}}} txwv tsis pub ua rau nplua {{20 {}} pore hom. Qhov kev yaug txoj kev siv cov dej kub siv cov dej kub thiab cov tshuaj ntxhua khaub ncaws nruab nrab rau cov kua nplaum uas tsis huv, ua raws li kom qhuav. Cov kuab tshuaj uas muaj kuab tshuaj pleev cov qauv kev haus dej haus cawv lossis acetone kom yaj cov olotic tshwj xeeb, uas tau muab tshem tawm nrog cov kuab tshuaj; Tus txheej txheem no yuav tsum muaj qhov cua kom txaus vim yog cov tshuaj yaj huab tais.
Muab cov xwm txheej ua kom tiav nyob thoob plaws kev lag luam
Kev siv ntawm Silica Gel Desiccants yog ntau thoob plaws hla ntau kev lag luam vim lawv cov hauj lwm ua tau zoo thiab kev nyab xeeb. Hauv cov khoom noj khoom haus thiab cov tshuaj ntsiav, me me 5 - gram cov khoom lag luam, xws li rau cov khoom ci ci, ua rau cov kev cai nruj. Kws Tshuaj Kho Mobileion -}}}}}}} Cov Qauv Siv Hluav Taws Xob, yog qhov kev tiv thaiv zoo hauv qab cov khoom siv hluav taws xob hauv qab no, tiv thaiv kev tso tshuaj ua kom zoo nkauj thiab tshuaj ntsiav spoilage. Nws yog qhov tseem ceeb rau siv tsuas yog tsis yog- qhia, dawb huv si silica gel rau kev tiv thaiv kev pheej hmoo lossis tsis muaj kev pheej hmoo noj ntawm cov xim tsis sib xws. Tsis pub dhau ntawm cov khoom siv hluav taws xob thiab kev lag luam thev naus laus zis, silica gel pob ntawv thiab thauj khoom ntawm cov hluav taws xob lub sij hawm thiab kev thauj khoom ntawm cov hluav taws xob lub sij hawm thiab corrosion, yog li txo qis tus nqi tsis ua hauj lwm. Lawv kuj tseem siv ntau yam hauv cov thawv xa khoom nyob ze nrog cov khoom siv noo noo nyob nrog cov khoom siv rhiab tseem qhuav thoob plaws kev mus ncig ntev. Rau kev lag luam lag luam, ntxhib-pore silica gel tau npaj kom tshem cov dej qab zib uas tuaj yeem ua rau corrosion thiab kev tsim cov kev thaiv ntawm cov roj hydrates. Hauv lub neej txhua hnub, cov pob ntawv me me tso rau hauv Wardrobes, cov hnab khau yuav pab tiv thaiv cov khau ntaub thiab muaj txiaj ntsig zoo rau kev tswj lub tsev. Ib yam li ntawd, cov khoom me me tuaj yeem muab tso rau hauv cov hnab ntawv ua suab paj nruag, thiab cov khoom siv suab paj nruag, thiab cov khoom siv tshuab hluav taws xob kom tiv thaiv cov khoom muaj txiaj ntsig ntawm cov av noo kev puas tsuaj thaum mus ncig ua si lossis chaw khaws cia.
