Gouache yog cov xim thoob ntiaj teb rau kev tsim cov xim sib xyaw. Tab sis rau cov xim yooj yim feem ntau tsis txaus los qhia qhov naturalness ntawm cov khoom. Cov kws tshaj lij pom zoo kom sib tov dawb kom tau txais cov xim tshiab. Yog li ntawd, dawb yog xav tau nyob rau hauv ntau qhov ntau. Thiab ntawm no ib lo lus nug uas muaj tseeb tshwm sim rau cov pib tshiab. Lawv feem ntau xav tsis thoob: Dab tsi yog qhov txawv ntawm zinc dawb thiab titanium dawb? Yam twg zoo dua los yuav? Peb yuav pab koj daws qhov teeb meem no.
Titanium Dawb
hom xim dawb no tau siv dav. Cov khoom tseem ceeb yog titanium oxide. Nws xyaum tsis tshwm sim hauv qhov xwm txheej, yog li lawv tau kawm yuav ua li cas rho tawm ntawm kev lag luam los ntawm sulfuric acid. Titanium dawb yog ib qho ntawm cov xim zoo tshaj plaws, yog li lawv yog lub hauv paus rau kev ua gouache. Rau cov menyuam yaus, qhov no yog cov khoom siv kos duab zoo tshaj plaws. Tsis tas li ntawd, nws adheres zoo rau ntau qhov chaw. Tab sis feem ntau siv rau kev ua haujlwm ntawm ntoo, ntawv lossis duab los qhia. Cov yam ntxwv tseem ceeb - muaj peev xwm ua tau zoo thiab sib npaug ntawm qhov chaw thiab tsis poob nws cov xim. Thaum sib xyaw nrog cov xim, tom qab ziab kom tiav, qhov ntxoov ntxoo ua ob peb lub suab sib zog.
Ntawm ntawm titanium dawb
Ua ntej, cov haujlwm ua los ntawm cov xim no tuaj yeem khaws cia rau lub sijhawm ntev. Txawm li cas los xij, lawv tsis zoo rau ib puag ncig. Qhov txaus ntshai tsuas yog ib qho kev nplua nuj ntawm lub teeb. Tseeb, nyob rau hauv lub hwj chim ntawm lub hnub, dawb yuav kis tau ib tug daj tint. Thiab dawb yuav provoke cov nyhuv ntawm "chalking", uas yog, graininess. Cov kws kos duab sim zam qhov no. Yog li ntawd, zinc los yog barite dawb yog ntxiv rau me me. Txoj kev no ua tau zoo heev. Thib ob, yog tias cov xim uas cov xim dawb yuav muab sib xyaw muaj cov organic pigments, tom qab lub sij hawm lub sij hawm tus qauv yuav tau ib tug xiav tint. Qhov no yog undesirable. Thib peb, muaj ob peb cov ntxhia xim xim uas nws zoo dua tsis txhob sib xyaw titanium dawb. Cov no yog ultramarine, cob alt, azure, cadmium thiab lwm yam. Ib qho nkauj zoo li no yuav ua rau "soapy" nyhuv.
Daim ntawv thov
Rau cov menyuam yaus, cov khoom siv zoo tshaj plaws rau kev muaj tswv yim yog titanium dawb. Lawv siv, txawm tias nrov, muaj ntau yam kev txwv. Ua ntej ntawm tag nrho cov, qhov no yog vim lub fact tias cov xim nws tus kheej yog matte thiab muaj zoo heev npog cov khoom. Yog, dawb tom qabib qho admixture ntawm titanium oxide yog kiag li incompatible nrog roj. Xim nyob rau hauv cov hlab yuav tsuas plam nws cov khoom, darken thiab yuav tsis pw ntawm lub canvas. Los ntawm txoj kev, titanium dawb kuj tsis yog siv los ua lub hauv paus rau kev pleev xim rau ntawm daim ntaub. Hauv qhov no, nws yog qhov zoo dua los npog qhov chaw nrog zinc tus neeg sawv cev. Tsis tas li ntawd, hom xim no tsis yog siv los tsim frescoes ntawm chalk lossis limestone puag.
Zinc White
Zinc dawb tau tsim txij thaum ub. Lawv yog cov khoom tseem ceeb ntawm tag nrho cov xim tsis muaj dej thiab cov kua roj vanish. Qhov no txhais tau tias cov xim tsis tuaj yeem diluted nrog dej. Rau cov hom phiaj no, tsuas yog oily Cheebtsam yog haum. Vim lawv cov khoom, xim dawb tsis muab cov peev txheej zoo li titanium. Tab sis lawv, sib tov nrog lwm cov xim, ntxiv pob tshab thiab saturation rau xim. Nyob ntawm lub hom phiaj, tus tswv xaiv titanium thiab zinc dawb rau kev ua haujlwm. Qhov txawv ntawm lawv yog dab tsi, nws paub zoo heev. Ib tus kws tshaj lij tau paub ntev ntev tau paub tias titanium, ntawm qhov tsis sib xws, ntxiv qhov kub hnyiab rau tus qauv.
Daim ntawv thov
Zinc dawb tuaj yeem pom nyob rau hauv yuav luag txhua cov ntaub ntawv hais txog kev kho kom zoo nkauj sab hauv. Nws yog cov khoom tseem ceeb thaum pleev xim rau phab ntsa, qab nthab, pem teb lossis rooj tog. Hauv kev kos duab, lawv kuj tau siv ntau zaus.

Txawm li cas los xij, zinc dawb yog qhov tseem ceeb thaum ua haujlwm nrog ntoo, iav, hlau,ntawv los yog plaster.
Qhov sib txawv ntawm zinc dawb thiab titanium dawb
Yog li qhov txawv ntawm titanium thiab zinc dawb yog dab tsi? Qhov txawv ntawm lawv yog dab tsi? Cov lus hauv qab no yuav pab teb cov lus nug no:
hom dawb | Zinc | YTitanium |
Cov peev xwm |
Nyob hauv paus translucent | Glides yooj yim nrog kev pabcuam zoo |
Khoom siv nrog | Ntoo, ntawv, cardboard, hlau, iav, plaster, txiv qaub | Ntoo, ntawv, cardboard, hlau |
Muaj peev xwm ua ke nrog lwm yam khoom | Combines yooj yim nrog cov xim tsuas yog roj. Tsis txhob dilute nrog kom qhuav cov roj, txwv tsis pub nws yuav tau ib tug daj tint | Muaj ntau hom organic thiab inorganic yam tsis ua ke |
Influence ntawm cov xim kawg | No effect | Ua ob peb ntxoov sib dua thaum qhuav tag |
Npaj qhov tseeb
Lub thev naus laus zis ntawm kev ua titanium dawb tau pom tsuas yog thaum kawg ntawm lub xyoo pua 19th. Thiab lawv tau pib siv nws hauv ntiaj teb thiab Russia txawm tias tom qab - los ntawm 20s ntawm lub xyoo pua 20th. Tias yog vim li cas cov neeg ua yeeb yam ua haujlwm kom txog thaum lub sijhawm ntawd tau kuaj xyuas qhov tseeb los ntawm kev txheeb xyuas cov ntsiab lus ntawm titanium hauv cov khoom xyaw.pleev xim. Los ntawm txoj kev, yog tias ilmenite pigment yog ntxiv rau cov tshuaj ntxuav tes zoo tib yam, ces nws yuav tsis muaj zog. Qhov no feature tau pom los ntawm engineers ntawm high-tech tshuab. Thiab tam sim no titanium dawb nrog ilmenite pigment npog lub hull ntawm spaceships.
