Kev txuag cov artwork yog cov txheej txheem ua kom zoo nkauj thiab zoo tshaj plaws uas yuav tsum tau xaiv ua tib zoo xaiv thiab muaj kev ncaj ncees ntawm cov duab kos duab. Cellulose muaj kev hais ua ke, ib pawg ntawm cov tebchaw tau muab los ntawm cellulose, tau pom cov ntawv thov hauv ntau yam kev lag luam rau lawv cov khoom siv thickenies, suav nrog cov thickening, ruaj khov, thiab dej khaws cia. Nyob rau hauv lub realm ntawm artwork kev txuag, kev nyab xeeb ntawmNeeg muaj neeg ua haujlwmyog qhov kev txiav txim siab tseem ceeb. Qhov kev qhia tshwj xeeb no tau tshawb txog kev nyab xeeb ntawm kev muaj kev nyab xeeb ntawm kev ua kom muaj kev nyab xeeb ntawm hydroxypropylulose (EHEC), thiab Cellulethyl Cellulose (CMC).
1. HydroxyProproyl Minthylcellaus (HPMC)
a. Kev siv ntau
HPMC yog ib txwm ua haujlwm hauv kev txuag rau nws cov khoom siv dej kom ceev. Nws cov xwm ntau yam ua rau nws haum rau kev tsim cov nplaum thiab cov neeg ua haujlwm hauv kev ua kom rov qab los ntawm daim ntawv cuav.
b. Kev txiav txim kev nyab xeeb
HPMC yog feem ntau suav tias yog kev nyab xeeb rau kev txuag cov artwork thaum siv cov lus Yudas. Nws cov kev sib raug zoo nrog ntau yam kev ua haujlwm thiab nws cov hauj lwm zoo hauv kev tswj cov qauv txheej txheem ntawm cov duab kos duab ua kev txhawb nqa rau nws qhov kev lees txais hauv kev txuag kev txuag.
2. Ethyl hydroxyethyl cellulose (EHEC)
a. Kev siv ntau
EHEC yog lwm lub cellulose etherized hauv kev txuag rau nws cov thickening thiab ruaj khov zog. Tej zaum nws yuav ua haujlwm hauv ntau cov qauv kom ua tiav cov yam xav tau.
b. Kev txiav txim kev nyab xeeb
Zoo ib yam li HPMC, EHEC tau txiav txim siab muaj kev nyab xeeb rau qee cov ntawv thov kev txuag. Nws siv yuav tsum tau dlhos nrog cov kev cai tshwj xeeb ntawm cov duab kos thiab yuav raug kuaj kom meej kom paub meej tias kev sib raug zoo.
3. Carboxymethyl cellulose (CMC)
a. Kev siv ntau
CMC, nrog nws cov khoom siv tuab thiab ruaj khov, nrhiav cov ntawv thov hauv kev lag luam ntau yam, suav nrog kev txuag. Nws yog xaiv raws nws lub peev xwm los hloov cov viscosity ntawm kev daws teeb meem.
b. Kev txiav txim kev nyab xeeb
CMC yog feem ntau suav tias yog kev nyab xeeb rau kev txuag tshwj xeeb kev txuag. Nws txoj kev nyab xeeb profile ua rau siv rau cov qauv npaj los ua kom ruaj khov thiab tiv thaiv artworks, tshwj xeeb hauv kev tswj puag ncig.
4. Kev txuag kev coj ua zoo tshaj plaws
a. Kev kuaj
Ua ntej thov ib lub cellulose ether rau artwork, conservators qhia txog qhov tseem ceeb ntawm kev ua kom tiav ntawm thaj chaw me me, tsis muaj ncauj. Kauj ruam no ua kom ntseeg tau tias cov khoom siv tau sib xws nrog cov duab kos thiab tsis muaj kev cuam tshuam tsis zoo.
b. Kev saj laj
Cov neeg saib xyuas kos duab thiab cov tub txawg ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov ntaub ntawv tsim nyog thiab cov hau kev tsim nyog rau kev txuag. Lawv cov kws tshaj lij qhia tawm cov kev xaiv ntawm cellulose muaj kev pab cuam cellulose thiab lwm cov ntaub ntawv kom ua tiav qhov txiaj ntsig kev txuag tau.
5. Kev Cai Ua Raws
a. Ua raws li cov qauv
Kev txuag kev txuag nrog cov qauv thiab cov txheej txheem tshwj xeeb thiab cov txheej txheem los xyuas kom qhov kev saib xyuas siab tshaj plaws rau kev saib xyuas artworks. Ua raws li cov qauv no yog qhov tseem ceeb los tswj kev nyab xeeb thiab kev ncaj ncees ntawm kev txuag kev txuag.
6.Cobcus
Cellulose pab neeg xws li HPMC, EHEC, thiab CMC tuaj yeem txiav txim siab muaj kev nyab xeeb rau kev txuag ntawm artwork thaum siv raws li kev coj ua zoo tshaj plaws. Cov kev sim txhij txhua, kev sab laj nrog cov kws kho mob, thiab kev yoog raws li cov neeg muaj kev nyab xeeb ntawm kev txuag cellulose hauv kev txuag cov kos duab hauv Artwork. Raws li lub tshav pob ntawm kev tshawb fawb tau hloov zuj zus, txuas ntxiv kev tshawb fawb thiab cov kws ua yeeb yam nrog cov cuab yeej txhim khu kev qha rau kev khaws cia peb cov cuab yeej cuab tam.
