Peb txhua tus twb muab lawv pov tseg lawm - cov pob me me, uas muaj cim "TSIS TXHOB NOJ" puv nrog cov hlaws xiav me me, pom muaj nyob rau hauv txhua yam los ntawm cov hnab tshiab mus rau cov thawv khoom siv hluav taws xob. Tab sis xiav silica gel tsis yog tsuas yog cov khoom ntim khoom xwb; nws yog ib qho cuab yeej muaj zog, siv tau dua uas zais cia rau hauv qhov muag pom. Kev nkag siab txog nws yog dab tsi, nws ua haujlwm li cas tiag tiag, thiab nws siv lub luag haujlwm tuaj yeem txuag nyiaj, tiv thaiv cov khoom, thiab txawm tias txo cov khib nyiab. Txawm li cas los xij, nws cov xim ci ntsa iab kuj zais qhov tseem ceeb ntawm kev nyab xeeb thiab kev xav txog ib puag ncig.
Lub Tswv Yim Khawv Koob Hauv Koj Lub Thawv Khau: Nws Ua Haujlwm Li Cas Yooj Yim
Xav txog ib daim txhuam cev, tab sis es tsis txhob nqus cov kua, nws nyiam cov pa dej uas tsis pom los ntawm huab cua. Ntawd yog silica gel - ib hom silicon dioxide uas ua rau cov hlaws lossis cov granules uas muaj qhov ntxeem tau ntau heev. Nws lub zog loj yog nws thaj chaw sab hauv loj heev, muab ntau qhov chaw rau cov dej kom lo rau (nqus). Qhov "xiav" yog los ntawm cobalt chloride, ntxiv rau ua lub ntsuas dej noo. Thaum qhuav, cobalt chloride yog xiav. Thaum cov gel nqus dej, cobalt ua haujlwm thiab hloov xim liab. Xiav txhais tau tias nws ua haujlwm; Liab txhais tau tias nws puv. Qhov pom tam sim ntawd no yog qhov ua rau cov xim xiav nrov thiab yooj yim siv.
Ntau Tshaj Li Khau Tshiab Xwb: Kev Siv Tau Txhua Hnub
Txawm hais tias muaj nyob rau hauv lub ntim khoom kom tiv thaiv pwm thiab dej noo puas tsuaj thaum lub sijhawm thauj mus los thiab khaws cia, cov neeg siv khoom txawj ntse tuaj yeem siv cov pob no dua:
Tus Cawm Seej Hluav Taws Xob: Muab cov pob khoom uas tau rov ua dua tshiab (xiav) tso rau hauv cov hnab koob yees duab, ze ntawm cov khoom siv computer, lossis nrog cov khoom siv hluav taws xob khaws cia kom tiv thaiv kev puas tsuaj los ntawm xeb thiab dej noo. Ua kom lub xov tooj puas los ntawm dej rov qab zoo li qub? Kev faus nws rau hauv lub thawv uas muaj silica gel (tsis yog mov!) yog ib kauj ruam kho mob thawj zaug uas tau lees paub.
Tus Saib Xyuas Cov Khoom Muaj Nqis: Muab cov pob khoom ntim rau hauv cov thawv cuab yeej kom tiv thaiv xeb, nrog rau cov ntaub ntawv tseem ceeb lossis cov duab kom tiv thaiv kev lo thiab pwm, hauv lub thawv phom, lossis nrog cov khoom siv nyiaj kom qeeb qeeb lwj. Tiv thaiv cov twj paj nruag (tshwj xeeb tshaj yog cov thawv ntoo) ntawm kev puas tsuaj los ntawm av noo.
Tus Neeg Pab Mus Ncig Ua Si & Chaw Khaws Khoom: Khaws cov khoom kom tshiab thiab tiv thaiv cov ntxhiab tsw phem los ntawm kev ntxiv cov pob khoom. Tiv thaiv cov khaub ncaws rau lub caij, cov hnab pw, lossis cov tsev pheeb suab kom tsis txhob ntub thiab pwm. Muab tso rau hauv cov hnab gym kom tiv thaiv cov dej noo thiab ntxhiab tsw uas nyob ntev.
Tus Pab Txhawb Nqa: Khaws cov noob kom qhuav rau kev khaws cia. Tiv thaiv cov khoom sau xws li cov ntawv xa ntawv, cov npib, lossis cov ntawv pauv lag luam kom tsis txhob puas tsuaj los ntawm cov av noo. Tiv thaiv kom cov av noo tsis nkag rau hauv lub teeb taub hau tsheb (muab cov pob khoom tso rau hauv cov khoom teeb taub hau kaw yog tias muaj thaum lub sijhawm kho).
Kev Khaws Duab & Xov Xwm: Khaws cov pob khoom uas muaj cov duab qub, cov yeeb yaj kiab tsis zoo, cov slides, thiab cov ntawv tseem ceeb kom tiv thaiv kev puas tsuaj los ntawm cov dej noo.
Cov Lus Ceeb Toom "Tsis Txhob Noj": Nkag Siab Txog Cov Kev Pheej Hmoo
Cov silica nws tus kheej tsis muaj tshuaj lom thiab tsis muaj zog. Qhov txaus ntshai tshaj plaws ntawm cov pob me me yog qhov txaus ntshai rau kev txhaws, tshwj xeeb tshaj yog rau cov menyuam yaus thiab tsiaj txhu. Qhov kev txhawj xeeb tiag tiag nrog cov silica gel xiav yog nyob rau hauv qhov qhia cobalt chloride. Cobalt chloride yog lom yog tias noj ntau ntau thiab raug cais ua cov carcinogen. Txawm hais tias qhov ntau hauv ib pob neeg siv khoom me me, kev noj yuav tsum tsis txhob. Cov tsos mob tuaj yeem suav nrog xeev siab, ntuav, thiab muaj peev xwm cuam tshuam rau lub plawv lossis thyroid nrog cov koob tshuaj ntau. Ib txwm khaws cov pob kom deb ntawm cov menyuam yaus thiab tsiaj txhu. Yog tias noj, nrhiav kev qhia kho mob lossis tiv tauj kev tswj tshuaj lom tam sim ntawd, muab lub pob yog tias ua tau. Tsis txhob tshem cov hlaws dai ntawm lub pob rau kev siv; cov khoom siv pob yog tsim los kom tso cai rau cov dej noo thaum khaws cov hlaws dai.
Tsis Txhob Pov Cov Gel Liab Dawb Ntawd! Kev Kos Duab ntawm Kev Rov Ua Dua Tshiab
Ib qho ntawm cov neeg siv khoom nkag siab yuam kev loj tshaj plaws yog tias silica gel siv tau ib zaug xwb. Nws siv tau dua! Thaum cov hlaws hloov xim liab (lossis xiav tsis ci), lawv puv tab sis tsis tuag. Koj tuaj yeem rov ua kom lawv rov ua haujlwm dua:
Txoj Kev Siv Qhov Cub (Zoo Tshaj Plaws): Muab cov gel uas muaj roj ntau rau hauv ib txheej nyias nyias rau ntawm daim ntawv ci. Ua kom sov hauv qhov cub ib txwm muaj ntawm 120-150°C (250-300°F) rau 1-3 teev. Saib xyuas kom zoo; kev kub dhau heev tuaj yeem ua rau cov gel puas tsuaj lossis lwj cov cobalt chloride. Nws yuav tsum tig rov qab mus rau xiav tob. CEEB TOOM: Xyuas kom cov gel qhuav tag ua ntej ua kom sov kom tsis txhob muaj teeb meem pa. Ua kom cua nkag rau thaj chaw vim tias yuav muaj ntxhiab me ntsis. Cia kom txias tag ua ntej kov.
Txoj Kev Siv Hnub (Qeeb dua, Tsis Txhim Khu Kev): Muab cov gel pleev rau hauv qhov chaw tshav ntuj ncaj qha thiab kub rau ob peb hnub. Qhov no ua haujlwm zoo tshaj plaws hauv huab cua qhuav heev thiab kub tab sis tsis huv npaum li qhov ziab hauv qhov cub.
Siv lub tshuab hluav taws xob microwave (Siv Ceev Faj Heev): Qee lub siv lub zog luv luv (piv txwv li, 30 vib nas this) ntawm lub zog nruab nrab, nthuav cov gel nyias nyias thiab saib xyuas tas li kom tiv thaiv kev kub dhau lossis hluav taws kub (muaj kev pheej hmoo ntawm hluav taws). Feem ntau tsis pom zoo vim muaj kev pheej hmoo ntawm kev nyab xeeb.
Qhov Teeb Meem Ib puag ncig: Kev Yooj Yim vs. Cobalt
Txawm hais tias silica gel yog inert thiab reactivable, cobalt chloride nthuav tawm qhov teeb meem ib puag ncig:
Kev Txhawj Xeeb Txog Kev Pov Tseg Khoom: Cov pob khoom pov tseg, tshwj xeeb tshaj yog cov khoom loj, ua rau muaj cov khib nyiab pov tseg. Txawm hais tias cobalt khi, tseem yog ib hom hlau hnyav uas zoo tshaj plaws yuav tsum tsis txhob nkag mus rau hauv dej hauv av ntev heev.
Kev Rov Ua Dua Tshiab Yog Qhov Tseem Ceeb: Cov kauj ruam tseem ceeb tshaj plaws rau ib puag ncig uas cov neeg siv khoom ua tau yog rov ua dua tshiab thiab siv cov pob khoom dua tshiab ntau li ntau tau, ua kom lawv lub neej ntev dua thiab txo cov khib nyiab. Khaws cov gel uas tau rov ua dua tshiab rau hauv cov thawv kaw.
Kev Pov Tseg: Ua raws li cov lus qhia hauv zos. Cov pob me me uas siv lawm feem ntau yuav muab pov tseg rau hauv cov thoob khib nyiab ib txwm muaj. Cov tshuaj gel loj dua lossis cov tshuaj gel loj heev yuav tsum tau pov tseg ua cov khib nyiab txaus ntshai vim muaj cobalt - xyuas cov cai. Tsis txhob nchuav cov tshuaj gel uas xoob rau hauv cov kav dej.
Lwm Txoj Kev Xaiv: Txiv Kab Ntxwv Silica Gel: Rau cov ntawv thov uas xav tau cov cim qhia tab sis cobalt yog qhov txhawj xeeb (piv txwv li, ze cov khoom noj, txawm tias tseem cais los ntawm kev thaiv), methyl violet-based "txiv kab ntxwv" silica gel siv. Nws hloov ntawm txiv kab ntxwv mus rau ntsuab thaum saturated. Txawm hais tias tsis muaj tshuaj lom, nws muaj kev rhiab heev rau cov dej noo sib txawv thiab tsis tshua muaj rau cov neeg siv khoom siv dua.
Xaus Lus: Ib Lub Cuab Yeej Muaj Zog, Siv Kom Zoo
Cov kua xiav silica yog ib yam khoom siv nqus dej noo uas zoo heev thiab siv tau ntau yam uas nyob hauv cov ntim khoom txhua hnub. Los ntawm kev nkag siab txog nws cov yam ntxwv qhia, kawm kom rov ua kom nws muaj kev nyab xeeb, thiab siv cov ntim khoom ntawd dua, cov neeg siv khoom tuaj yeem tiv thaiv lawv cov khoom thiab txo cov khib nyiab. Txawm li cas los xij, kev hwm rau cov lus ceeb toom "Tsis Txhob Noj" thiab kev paub txog cov ntsiab lus cobalt - qhov tseem ceeb tshaj plaws yog kev tuav pov hwm kom muaj kev nyab xeeb, kev rov ua kom zoo, thiab kev pov tseg kom raug - yog qhov tseem ceeb rau kev siv lub zog ntawm cov khoom xiav me me no yam tsis muaj qhov tshwm sim tsis xav tau. Nws yog ib qho pov thawj ntawm kev tshawb fawb yooj yim daws cov teeb meem txhua hnub, xav tau kev txaus siab thiab kev siv ceev faj.
