Silica gel desiccant - cov me, feem ntau cov Papery cov pob ntim nrog lub siab tawv " Lawv muaj cov lus nug: yog silica gel desiccant thiaj muaj kev nyab xeeb? Lo lus teb, zoo li ntau yam, yog nuanced: yog, silica gel feem ntau suav hais tias yog feem ntau tsis muaj kev nyab xeeb thaum siv, tab sis ceev faj yog qhov tseem ceeb.
Kev nkag siab silica gel
Firstly, nws yog qhov tseem ceeb kom nkag siab dab tsi Silica gel yog. Txawm hais tias nws lub npe, nws tsis yog gel txhua. Nws yog synthetically tsim cov khoom ntawm silicon dioxide (sitio₂), tib cov ntxhia pom pom ib txwm nyob hauv Quartz thiab xuab zeb. Lub "gel" yog hais txog nws cov qauv sab hauv - lub hws microscopic ntawm lub hws uas muab rau nws qhov loj me. Cov qauv tseem ceeb no yog qhov zoo tshaj plaws ntawm adsorbing (nyiam thiab tuav) dej vapor los ntawm cov huab cua ib puag ncig, ua rau nws zoo heev desiccant.
Hais txog kev txhawj xeeb txog kev nyab xeeb thawj
- Kev noj (noj): Qhov no yog qhov kev txhawj xeeb tshaj plaws, tau siv los ntawm cov lus ceeb toom uas muaj koob tsheej.
- Qhov xov xwm zoo: ntshiab, unpoped silica gel yog cov inert thiab tsis - pa. Yog tias kev noj los ntawm ib tus neeg laus, tus menyuam, lossis tsiaj, nws tsis zoo li yuav tsum tau nqus los ntawm lub cev lossis ua rau lom. Nws ib txwm kis dhau los ntawm lub plab zom mov tsis hloov pauv.
- Qhov kev pheej hmoo tiag tiag: Thawj qhov kev phom sij ntawm kev noj yog cov kho tshuab:
- Choking Das: Cov pob ntawv lawv tus kheej, tshwj xeeb tshaj yog cov menyuam yaus, tshwj xeeb rau cov menyuam mos, thiab tsiaj me.
- Kev nkag siab hnyuv: Thaum tsis tshua muaj, siv ntau ntau ntawm silica gel cov hlaws dai yuav muaj peev xwm ua rau muaj kev thaiv hauv plab zom mov.
- "Tsis txhob noj" lub hom phiaj: Cov lus ceeb toom uas muaj kev tiv thaiv cov coking / txhaws ntswg txaus, tsis yog vim tias cov khoom noj muaj tshuaj silica.
Daim tawv nqaij tiv tauj
- Tuav cov pob zeb Silica Gel feem ntau muaj kev nyab xeeb. Txawm li cas los xij, cov hlaws dai lawv tus kheej tuaj yeem ua kom me ntsis hauv cov khoom loj.
- Qhov kev txhawj xeeb tseem ceeb yog qhov ua kom qhuav. Silica gel yog tsim los nqus dej noo. Ntev ntev lossis rov ua haujlwm ncaj qha nrog cov nqi loj tuaj yeem ua rau tawv nqaij qhuav lossis khaus me me, tshwj xeeb yog rau cov tawv nqaij rhiab. Ntxuav tes tom qab kov tau yooj yim xyaum.
Qhov muag hu
Tau txais Silica Gel hlaws dai lossis hmoov av nyob rau hauv lub qhov muag tuaj yeem ua rau tseem ceeb tshaj plaws, liab, thiab tsis xis nyob vim muaj kev puas tsuaj. Dej ntws yaug qhov muag tam sim ntawd nrog dej huv tsawg kawg yog 15 feeb thiab nrhiav kev kho mob yog tias khaus khaus.
Siv nqus tau
Thaum tsis yog qhov kev pheej hmoo loj los ntawm cov pob khoom sib tsoo, nqus tau cov hmoov av silica gel (uas tuaj yeem ua kom lub qhov ntswg) tuaj yeem ua rau lub qhov ntswg, caj pas, thiab ua pa ua pa. Cov tib neeg muaj mob hawb pob lossis lwm yam ua pa yuav muaj kev nkag siab ntau. Muaj nqis los tuav Bulk Silica gel xav kom haum cov hmoov av tswj kev ntsuas.
Tseem ceeb hloov pauv: Qhov taw qhia Silica gel
- Xiav silica gel: ib txwm ua: Silica gel feem ntau tau dopalt nrog cobalt chloride los ua raws li qhov ntsuas dej noo (xiav thaum qhuav, liab dawb thaum muaj). Cobalt chloride yog suav tias yog tshuaj lom thiab muaj peev xwm carcinogen. Thaum noj kev pheej hmoo los ntawm ib pob ntawv yog tseem tsawg, hom no yuav tsum ua tib zoo saib xyuas thiab pov tseg. Cov kev cai (tshwj xeeb yog nyob rau hauv EU) tau txwv nws siv ntau.
- Txiv kab ntxwv Silica Gel: Qhov no yog cov niaj hnub, kev nyab xeeb lwm yam ntsuas. Nws siv methyl violet, uas yog tsis - pa. Nws hloov los ntawm txiv kab ntxwv rau ntsuab thaum muaj cov. Cov txiv kab ntxwv silica gel tam sim no tus qauv ntsuas qauv rau cov neeg siv khoom siv feem ntau.
Khoom noj khoom haus - qib sillica gel
Silica gel siv nyob rau hauv cov ntawv thov zaub mov ncaj qha (zoo li cov khoom noj khoom haus hauv spice lossis ntim cov tawv nqaij (piv txwv li, FDA hauv EU). Qhov no "zaub mov {- gel yog ntsuas kom muaj kev phom sij kom ntseeg tau tias tsis muaj kev phom sij thaum siv tau.
Kev Nyab Xeeb Kev Ua Haujlwm Zoo Tshaj
- Ua kom ncav cuag: Khw Silica Gel pob kom ruaj khov ntawm cov menyuam yaus thiab tsiaj kom tiv thaiv kev phom sij zawm caj ces.
- Tsis txhob noj: mloog cov ntawv ceeb toom. Thaum tsis - kev lom zem, noj tsis muaj kev nyab xeeb vim yog choking / blockage txaus ntshai.
- Lis kom zoo zoo: zam cov pob ntawv ua kua muag yam tsis muaj. Yog hais tias cov hlaws dai kom huv, ntxuav lawv (cov hnab looj tes yog tias rhiab) thiab muab pov tseg kom zoo.
- Kev tiv thaiv qhov muag: Ceev faj kom tsis txhob tau txais cov hlaws dai hauv qhov muag. Hnav tsom iav kev nyab xeeb yog tias tuav ntau ntau lossis cov khoom siv plua plav.
- Cov khoom pov tseg kom zoo: Cov khoom me me feem ntau tuaj yeem mus rau hauv tsev pov tseg cov thoob tsev neeg. Cov khoom loj dua lossis qhov ntsuas Gel (tshwj xeeb tshaj yog cov xim xiav, yog tias ntsib) yuav xav tau kev tswj hwm hauv zej zog. Tsis txhob yaug tawm hauv dej.
- Siv cov zaub mov -} qib tsuas yog rau cov khoom noj: tsis hloov chaw tsis yog-}}}}}}}}}}}}}}}}}}

Silica gel desiccant yog qhov kev nyab xeeb zoo thiab muaj kuab cov huab cua zoo thaum tuav lub luag haujlwm. Nws cov khoom siv tseem ceeb, silicon dioxide, tsis yog - ua kua roj thiab inert. Qhov tseem ceeb kev nyab xeeb kev txhawj xeeb tshwj xeeb feem ntau ntawm cov kev phom sij ntawm lub cev nqaij daim tawv thiab mob plab zom mov, thiab kev ua pa rau cov laus uas muaj cov cobalt chloride.
Los ntawm kev nkag siab cov kev pheej hmoo no, heeding lub "tsis noj" lus ceeb toom, thiab siv cov pob txiv kab ntxwv (li cov khoom siv txiv kab ntxwv (silica gel tuaj yeem siv tau kev nyab xeeb thiab cov khoom lag luam sib luag. Nws lub luag haujlwm hauv kev tiv thaiv cov khoom muag los ntawm noo noo kev puas tsuaj deb deb outweighs cov kev pheej hmoo tswj hwm tau nrog nws siv kom raug.
