Gesso - yog dab tsi? Yuav ua li cas gesso nrog lawv ob txhais tes?

Muaj ntau nyob rau hauv lub kho ntawm qhov muaj txojkev ib lub sij hawm xws li gesso. Yuav ua li cas nws yog, Kuv tsis paub txhua leej txhua tus. Vim hais tias ntawm no, thiab tej zaum yuav muaj teeb meem nrog cov kho kom zoo nkauj ntawm cov phab ntsa nrog nws tus kheej txhais tes.

Gesso phab ntsa - finishing ntawm lub siab tshaj plaws zoo nrog rau kev siv tshwj xeeb cov ntaub ntawv. Nyob rau hauv Feem ntau, qhov no yog coj mus rau chalk los yog gypsum mortar. Qhov no txoj kev no yog tsim rau cov xov qhov kev npaj ntawm cov phab ntsa ua ntej painting.

Technology thov levkas

Otshtukaturivanie phab ntsa siv cov txheej txheem no yuav ua tau nws tus kheej. Tag nrho cov ua hauj lwm yuav siv sij hawm qhov chaw nyob rau hauv ob peb theem:

1. Preparative purification theem implies ib lub phab ntsa nto ntawm lub qub txheej. Ntxuav yuav tsum sib sib zog nqus, yog li ntawd txawm tsim nyog los tshem tawm ib tug txheej ntawm plaster.
2. Ua tib zoo xyuas qhov chaw ntawm cov phab ntsa. Tag nrho cov uas twb muaj lawm tej kab nrib pleb thiab qhov (tab sis sib sib zog nqus) yuav tsum tau kho nrog putty. Rau ntawm no theem nws yog tsim nyog los siv ib tug muaj pes tsawg leeg raws li xis mas. Nws tseem yog tau noj thiab alabaster (qhuav mix raws li gypsum), tshwj xeeb tshaj yog yog hais ntxiv gesso npaj. Yuav ua li cas nws yog, nws twb tau piav ua ntej lawm nyob rau hauv no tsab xov xwm.
3. Qhov chaw nyob qhov twg muaj ib tug tshwj xeeb loj tej kab nrib pleb, nyob rau hauv tas li ntawd mus Maas plaster yuav tsum lo steklosetchatkoy. Tsis tas li ntawd rau lub hom phiaj no yuav siv tau serpyanka.
4. Tsuas yog tom qab tag nrho cov tau loj tsis xws luag tau raug tshem tawm, nws yog tau mus nqa tawm lub primer. Qhov no yuav tsis nyob ntev yog tsis muaj nyob hauv txhua rooj plaub tsis yooj yim sua. Lub fact tias cov primer muaj ib tug heev ib qho tseem ceeb muaj nuj nqi. Ua tsaug rau nws, koj muaj peev xwm ua tau lub siab tshaj plaws tsevneeg ntawm xov ntaub ntawv mus rau qhov chaw ntawm cov phab ntsa, thiab nws minimizes yuav uas lub putty yuav ploj.
5. Tom qab priming imposes planarization txheej putty. Nws thickness yuav tsum tau me ntsis raws li 2 hli. Qhov no thickness yuav tsum yuav txaus ua nyob rau hauv ib txig tiaj. Yog hais tias koj ua tau qhov no tsis tau, ces koj ua ntawv thov lwm txheej, tab sis txhua successive txheej ntawm putty yuav tau mus thov tsuas yog hais tias tus yav dhau los qhuav kiag li.
6. Primer txheej.
7. Tsuas yog tam sim no muaj peev xwm thov gesso phab ntsa nrog nws tus kheej txhais tes, siv cov muaj pes tsawg leeg ntawm chalk los yog txiv qaub. Ua tib zoo saib rau uniformity ntawm daim ntawv thov ntawm cov khoom.

Tom qab gesso (uas yog nws twb tau piav saum toj no) yog kiag li qhuav, nws tseem tau mus pib painting los yog wallpapering.

Tau patterned paintings

Gesso (dab tsi nws yog piav nyob rau hauv tsab xov xwm) yog siv thiab yog hais tias tus phab ntsa yuav tso nrog tshwj xeeb patterned paintings. Nyob rau hauv cov ntaub ntawv no, lub tshuab yog ib tug me ntsis txawv:

1. Tag nrho cheeb tsam yuav tsum tau muab faib ua plaub fab nrog ib tug sab ntawm 30 los yog 40 cm.
2. Nyob rau txhua square qauv yog xaiv los kom ib tug qauv uas khij.
3. By tso kab thov plaster tshuaj, qhov yuav tsum tau ua tib zoo xyuas kom meej tias cov qauv qauv muaj tib tus qauv nyob rau hauv txhua square.
4. Cia ob hnub kom qhuav.
5. Tshem tawm tej unevenness (kom tsis txhob rau lawv, hmoov tsis, tsis tau zoo) siv ib tug tshwj xeeb phua ntiag.

Tam sim no, cov phab ntsa yuav tsum pleev xim rau nrog ib tug qauv. Nyob rau hauv cov ntaub ntawv ntawm gesso yog zoo dua rau muab kev xaiv li cas rau acrylic dej-xim.

Muaj pes tsawg leeg ntawm gesso

Muaj ob qho kev xaiv gesso: siv chalk los yog txiv qaub. Raws li lawv tsis tawm los mus rau txhua lwm yam, tab sis muaj ib co sib txawv nyob rau hauv qhov kev npaj ntawm cov tshuaj.

Gesso yuav noj lawv tus kheej txhais tes. Raws li sib tov ntawm cwj mem av dawb:

• 5 litres ntawm cov dej;
• 3 kg sieved cwj mem av dawb;
• 30 g ntawm nplaum.

Dej yuav tsum tau rhuab mus txog 40-50 degrees. Tom qab ntawd, lub tank sau sifted cwj mem av dawb, coj mus rau nws cov tiav nyias mus nyias, thiab tsuas yog tam sim no yog tau ua kom paub nplaum sib tov. Care yuav tsum tau coj hais tias cov muaj pes tsawg leeg yog homogeneous, tsis muaj lumps.

txiv qaub gesso

Rau txiv qaub gesso yog tsim nyog los npaj:

• 2-3 kg slaked dej qab zib;
• 0.5 kg ntawm cov xim;
• 50-80 g ntawm sodium tshuaj dawb;
• 150-200 g ntawm potash alum ;
• dej.

Lub peculiarity ntawm muaj pes tsawg leeg - hais tias nws yuav tsum tau mus thov tsuas rau lub wetted nto ntawm cov phab ntsa.

Caulking rau gesso

Tshwj xeeb premixed gypsum-raws li, xws li "Knauf", "Weber Vetonit", "Klims", "IVSIL". Lawv siv, Yog hais tias lub hom phiaj yog kom tau peb-dimensional qauv. Ua noj ua haus lawv yuav tsis siv sij hawm ntau lub sij hawm, raws li ib tug qhuav hmoov sufficiently diluted nrog dej mus rau lub xeev ntawm viscosity.

Tom qab ua noj ua haus, tej sib tov yuav tsum tau xyuas cov theem ntawm viscosity, raws li qhov no parameter zaum yuav cuam tshuam qhov zoo tshaj ntawm zaum kawg tshwm sim. No me me nqi ntawm cov khoom yuav tsum tau thov kom muaj ib nqaim duav, uas ces nthuav mas. Nyob rau hauv no qhov teeb meem no rau hauv lub ntoos sib xyaw yuav tsum maj mam swb cia, uas qhia tau hais tias cov kam ntawm putty. Yog hais tias nws yog muab ib yam nkaus thiab kua, ces koj yuav tau ntxiv ib me ntsis hmoov tivthaiv, yog hais tias nws yog heev tuab - dej. Saib cov theem ntawm viscosity yog tsim nyog thaum twg lub batch yog muaj.

Cov cuab yeej rau gesso

Ua ntej ua gesso, koj yuav tsum npaj thiab tshwj xeeb cov cuab yeej:

1. Lub pneumatic Cav Tshuab Pa Tshuaj los yog sprayer, rau ntawm cov phab ntsa chalk los yog txiv qaub. Koj kuj siv tau cov phau ntawv counterpart, txawm li cas los, yuav tsum coj mus rau hauv tus account lub cheeb tsam ntawm lub kho nto ntawm cov phab ntsa. Thaum uas siv cov tshuab cua sprayer, koj yuav tau saib xyuas thiab tshuaj, nyob rau hauv particular, nws txhawj xeeb hnab looj tes, tsom iav thiab qhov ncauj.
2. Txhuam QAB NTHAB. Pheej yig dua hloov rab phom. Lub ntsiab kev siv ntawm no lub cuab tam yog cov kev taw qhia uas tso npe thov lub sib tov rau gesso. Koj yuav tsum tau thov ob peb khaubncaws sab nraud povtseg, lub yav tas ob yuav tsum perpendicular mus rau txhua lwm yam, thiab lub xeem - xa mus rau lub qhov rais. Qhov no txoj kev ntawm daim ntawv thov tso cai tsis txhob sib nrauj los ntawm tus txhuam.
3. Ib tug dav duav mus thov cov khov gypsum putty. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum ua raws li tej yam cov kev cai. Tus nqi ntawm cov khoom uas yog thov mus rau lub trowel yuav tsum tsis txhob yuav ntau heev thiab heev me ntsis. Thov lub sib tov yuav tsum yog los ntawm tej yooj yim qhov chaw, tab sis, raws li ib tug txoj cai, ua nws zoo dua lub kaum sab xis. Taw yuav tsum tau arc-zoo li tus, nrog ib tug nyias txheej ntawm lub sib tov. Txhua uas nyob ib sab txheej yuav tsum tau superimposed sib tshooj lub ntej ib.

Koj yuav tau npaj ib tug laum nrog ib tug tshwj xeeb nozzle mus tau yooj yim thiab effortlessly npaj cov muaj pes tsawg leeg ntawm kev kawm taub hau.

Gesso - ib txoj kev rau tag, uas yuav ua tau tsis tsuas yog nyob rau ntawm cov phab ntsa, tab sis kuj nyob rau hauv lub qab nthab, uas yuav npaj ib chav tsev nyob rau hauv ib style.
