Peb txhua tus tau pov lawv ib sab - cov pob ntawv me me uas cim "Tsis txhob noj" muaj cov hlaws xiav me me, pom nyob rau hauv txhua yam los ntawm cov hnab nyiaj tshiab mus rau lub thawv khoom siv. Tab sis xiav silica gel yog ntau tshaj li ntim muab tub lim; nws yog ib tug haib, reusable cuab tam nkaum nyob rau hauv dawb pom. Kev nkag siab tias nws yog dab tsi, nws ua haujlwm li cas, thiab kev siv lub luag haujlwm tuaj yeem txuag nyiaj, tiv thaiv cov khoom, thiab txawm tias txo cov khoom pov tseg. Txawm li cas los xij, nws cov xim vibrant tseem zais qhov tseem ceeb ntawm kev nyab xeeb thiab kev xav txog ib puag ncig.
Lub Magic Trick nyob rau hauv koj lub Shoebox: Yuav ua li cas nws ua hauj lwm yooj yim
Xav txog daim txhuam cev, tab sis es tsis txhob ntub dej, nws nyiam cov dej tsis pom los ntawm huab cua. Qhov ntawd yog silica gel - ib daim ntawv ntawm silicon dioxide ua tiav rau hauv cov hlaws dai lossis granules. Nws lub hwj chim loj yog nws thaj chaw loj sab hauv, muab suav tsis txheeb rau cov dej molecules los lo rau (adsorb). Qhov "xiav" yog los ntawm cobalt chloride, ntxiv rau hauv lub ntsuas dej noo. Thaum qhuav, cobalt chloride yog xiav. Raws li cov gel adsorbs dej, cobalt reacts thiab tig liab. Xiav txhais tau tias nws ua haujlwm; Pink txhais tau tias nws puv. Qhov kev pom tam sim no yog dab tsi ua rau xiav variant thiaj li nrov thiab siv tau zoo.
Ntau tshaj li Cov Khau Tshiab: Cov Tswv Yim Siv Txhua Hnub
Thaum suav nrog hauv ntim los tiv thaiv pwm thiab ya raws kev puas tsuaj thaum thauj thiab khaws cia, cov neeg siv khoom siv tau zoo tuaj yeem rov ua cov pob ntawv no:
Tus Cawm Seej Electronics: Muab cov khoom siv rov ua dua tshiab (xiav) hauv cov hnab ntim cov koob yees duab, nyob ze cov cuab yeej siv computer, lossis nrog cov khoom siv hluav taws xob khaws cia kom tiv thaiv corrosion thiab condensation puas. Revive lub xov tooj dej puas lawm? Muab faus rau hauv ib lub thawv ntawm silica gel (tsis yog mov!) yog ib qho pov thawj thawj kauj ruam.
Tus Saib Xyuas Ntawm Qhov Tseem Ceeb: Muab cov ntawv ntim rau hauv lub thawv rau kev tiv thaiv xeb, nrog rau cov ntaub ntawv tseem ceeb lossis cov duab los tiv thaiv cov kab mob thiab pwm, hauv phom phom, lossis nrog cov khoom siv nyiaj kom qeeb tarnishing. Tiv thaiv cov twj paj nruag (tshwj xeeb yog rooj plaub ntoo) los ntawm cov av noo puas.
Travel & Storage Companion: Khaws lub nra tshiab thiab tiv thaiv kom tsis txhob muaj ntxhiab tsw los ntawm kev ntxiv pob ntawv. Tiv thaiv cov khaub ncaws raws caij nyoog, cov hnab pw tsaug zog, lossis cov tsev pheebsuab los ntawm kev ntub dej thiab pwm. Muab tso rau hauv lub hnab gym los tiv thaiv lingering ya raws thiab tsw.
Hobbyist Helper: Khaws cov noob kom qhuav rau kev khaws cia. Tiv thaiv cov khoom siv xws li nyiaj muas, npib, lossis daim npav ua lag luam los ntawm kev puas tsuaj los ntawm cov av noo. Tiv thaiv kom tsis txhob ya raws huab cua hauv lub tsheb teeb taub hau (tso cov ntawv ntim rau hauv lub teeb lub taub hau yog tias siv tau thaum kho).
Photo & Media Preservation: Khaws cov pob ntawv nrog cov duab qub, zaj duab xis tsis zoo, slides, thiab cov ntaub ntawv tseem ceeb los tiv thaiv kev degradation ntawm noo noo.
Cov Lus Ceeb Toom "Tsis Txhob Noj": Nkag siab txog qhov pheej hmoo
Lub silica nws tus kheej yog non-toxic thiab inert. Qhov teeb meem tseem ceeb ntawm cov pob ntawv me me yog qhov ua rau muaj kev phom sij, tshwj xeeb tshaj yog rau menyuam yaus thiab tsiaj. Qhov kev txhawj xeeb tiag tiag nrog xiav silica gel nyob hauv qhov taw qhia cobalt chloride. Cobalt chloride yog tshuaj lom yog tias noj ntau npaum li cas thiab raug cais raws li cov kab mob carcinogen. Txawm hais tias tus nqi hauv ib pob khoom siv tsawg tsawg, kev noj yuav tsum zam. Cov tsos mob tuaj yeem suav nrog xeev siab, ntuav, thiab muaj peev xwm cuam tshuam rau lub plawv lossis cov thyroid nrog koob tshuaj loj. Nco ntsoov khaws cov pob ntawv kom deb ntawm menyuam yaus thiab tsiaj. Yog tias noj, nrhiav kev kho mob lossis tiv tauj rau kev tswj tshuaj lom tam sim ntawd, muab lub pob ntawv yog tias ua tau. Tsis txhob tshem cov hlaws dai ntawm lub pob khoom siv; cov ntaub ntawv ntim khoom yog tsim los kom muaj dej noo nyob rau hauv thaum khaws cov hlaws dai.
Tsis txhob pov qhov Pink Gel! Lub Art ntawm Reactivation
Ib qho ntawm cov neeg siv khoom tsis txaus ntseeg loj tshaj plaws yog tias silica gel yog siv ib zaug. Nws yog reusable! Thaum cov hlaws tig liab dawb (lossis qis dua vibrant xiav), lawv saturated tab sis tsis tuag. Koj tuaj yeem rov qhib lawv:
Qhov Cub Txoj Kev (Qhov Zoo Tshaj Plaws): Tshaj tawm saturated gel hauv ib txheej nyias ntawm daim ntawv ci. Tshav kub hauv qhov cub zoo li ntawm 120-150 ° C (250-300 ° F) rau 1-3 teev. Saib xyuas zoo; overheating tuaj yeem ua rau cov gel los yog decompose cobalt chloride. Nws yuav tsum tig rov qab mus rau qhov tob xiav. CEEB TOOM: Xyuas kom cov gel qhuav tag ua ntej cua sov kom tsis txhob muaj teeb meem ntawm chav. Ua pa ntawm thaj chaw raws li qhov tsw me ntsis tuaj yeem tshwm sim. Cia txias tag ua ntej tuav.
Txoj Kev Tshav Ntuj (Slower, Less Reliable): Spread gel indirect, hot sunlight for ob peb hnub. Qhov no ua haujlwm zoo tshaj plaws nyob rau hauv qhuav heev, kub huab cua tab sis yog tsawg dua qhov cub kom qhuav.
Microwave (Siv ceev faj heev): Qee tus siv cov tawg luv luv (xws li, 30 vib nas this) ntawm lub zog nruab nrab, kis cov gel nyias nyias thiab saib xyuas tas li kom tsis txhob muaj cua sov lossis tawg (xws li hluav taws kub). Feem ntau tsis pom zoo vim muaj kev nyab xeeb.
Environmental Dilemma: Convenience vs. Cobalt
Thaum silica gel yog inert thiab reactivatable, cobalt chloride nthuav qhia ib puag ncig kev sib tw:
Kev txhawj xeeb txog kev pov tseg: Cov pob ntawv pov tseg, tshwj xeeb tshaj yog nyob rau hauv ntau, ua rau cov pov tseg pov tseg. Lub cobalt, thaum khi, tseem yog cov hlau hnyav uas zoo tshaj plaws yuav tsum tsis txhob nkag mus rau hauv av hauv lub sijhawm ntev.
Reactivation yog Qhov Tseem Ceeb: Qhov tseem ceeb tshaj plaws ntawm ib puag ncig cov neeg siv khoom tuaj yeem ua tau yog rov ua dua thiab rov siv cov pob ntawv kom ntau li ntau tau, ncua lawv txoj sia thiab txo cov khoom pov tseg. Khaws cov reactivated gel rau hauv cov thawv airtight.
Pov Tseg: Ua raws li cov lus qhia hauv zos. Cov pob khoom siv me me tuaj yeem mus rau hauv cov thoob khib nyiab li niaj zaus. Cov khoom loj dua lossis cov khoom lag luam loj tuaj yeem xav tau pov tseg raws li cov pov tseg pov tseg vim muaj cov ntsiab lus cobalt - xyuas cov cai. Tsis txhob nchuav gel rau hauv cov dej ntws.
Lwm txoj hauv kev: Txiv kab ntxwv Silica Gel: Rau cov ntawv thov uas qhov ntsuas xav tau tab sis cobalt yog ib qho kev txhawj xeeb (xws li, nyob ze cov khoom noj, txawm tias tseem sib cais los ntawm kev thaiv), methyl violet-based "txiv kab ntxwv" silica gel yog siv. Nws hloov ntawm txiv kab ntxwv mus rau ntsuab thaum saturated. Thaum tsis muaj tshuaj lom, nws muaj qhov sib txawv ntawm cov dej noo thiab tsis tshua muaj rau cov neeg siv khoom rov qab siv dua.
Cov ntsiab lus: Cov cuab yeej muaj zog, siv ntse
Blue silica gel yog qhov ua tau zoo heev thiab muaj ntau yam noo noo absorber zais hauv cov ntim txhua hnub. Los ntawm kev nkag siab txog nws cov cuab yeej taw qhia, kawm kom rov ua kom muaj kev nyab xeeb, thiab rov ua dua cov pob ntawv, cov neeg siv khoom tuaj yeem tiv thaiv lawv cov khoom thiab txo cov khoom pov tseg. Txawm li cas los xij, kev hwm rau "Tsis Txhob Noj" cov lus ceeb toom thiab kev paub txog cov ntsiab lus cobalt - ua kom muaj kev nyab xeeb ua ntej, ceev faj txog kev ua kom rov ua haujlwm dua, thiab lub luag haujlwm pov tseg - yog qhov tseem ceeb rau kev siv lub zog ntawm qhov me me xiav marvel yam tsis muaj qhov tshwm sim. Nws yog ib qho pov thawj rau kev tshawb fawb yooj yim daws teeb meem txhua hnub, thov kom muaj kev txaus siab thiab siv ceev faj.
