Peb xaiv qhov ua tiav Putty nyob rau hauv painting los ntawm 3 tus tsiaj nrov

Peb disassemble cov yam nta ntawm plaster, xis mas thiab polymer ua tiav putty thiab subtleties ntawm lawv daim ntawv thov.

Ua ntej xov, phab ntsa saum npoo yuav tsum yog fluless. Txhua yam tob tob thiab cov leeg yog txav txawv, tshwj xeeb yog tias koj tau npog lawv nrog lub ci ci ci. Txawm tias impercenibies tsis xwm yeem yuav muaj peev xwm siv qhov pom. Qhov teeb meem yuav daws cov khoom siv yas yas raws li cov plaster, xis mas lossis polymers. Lawv tau thov nrog cov spatula ntawm qhov kawg ntawm cov cua ntsawj ntshab ua haujlwm thiab ua haujlwm rau kev ua tiav zaum kawg. Txhawm rau tiv thaiv kev ua haujlwm, koj tsis tas yuav muaj kev txawj tshwj xeeb, xws li ntawm cov plaster. Rau kev tso koj yuav xav tau ib qho spatula thiab lub taub ntim me me uas cov tshuaj yog pawg. Tsis muaj teeb meem nyob ntawm no. Nws tseem yuav daws tau tsuas yog ib lo lus nug - uas ua tiav putty yog qhov zoo dua.

Nta ntawm cov khoom siv

Tsis zoo li cov kev sib xyaw ua ke, qhov loj tau muaj cov khoom txhim kho. Nws qhov kev xav tau ntau dua, nyob ntawm txoj haujlwm nws yuav tsum tau ua.

Txhawm rau kom tau txais cov yam ntxwv tsim nyog, qhov tshwj xeeb yog xav tau, cov cim hauv cov tshuaj lom neeg thiab lub cev tsis sib xws.

Cov yam ntxwv txawv:

• Kev rho tawm me me yog tsim nyog nyob rau hauv kev txiav txim rau saum npoo yuav zoo kawg nkaus du. Nws yog qhov ua tau kom tau txais cov txiaj ntsig xav tau nrog kev pab ntawm plaster, tab sis nws cov qauv suav nrog cov khoom loj. Qhov ib txwm siv pawg siv los npaj rau tag nrho ua tiav muaj cov khoom me me, tab sis lawv loj dhau. Lawv tshwm sim los ntawm cov xim ci thiab ua kom nws daim iav nyhuv.

Cov cuab yeej no tso cai rau koj los sau cov emptiness, nrog rau kev nqaim thiab sib sib tsoo. Thaum siv cov tshuab ntxhua khaub ncaws, cov txheej txheem tsis tas yuav tsum siv zog, uas txhim kho cov haujlwm zoo. Nrog lub zog muaj zog, nws nyuaj dua los laij cov rog thiab muab cov tawv me me.
• Zoo adhesion yog lub peev xwm los ua raws li lub hauv paus. Kev rho tawm me me hauv kev ua ke nrog kev hloov kho kev sib ntxiv txhim kho cov clutch ntawm cov khoom siv nrog lub hauv paus uas nws tau thov. Nws yuav tsum tuav qhov ua tiav, txawm tias kev sib txhuam, tawg, kub thiab av sib txawv, lwm yam kev cuam tshuam ntawm lub cev.

Thawj qhov yuav tsum tau ua

Qhov zoo ntawm txheej yog kwv yees rau ntau cov txheej txheem:

• Mos muag thiab elasticity.
• Elasticity - cov khoom yuav tsum tsis txhob kis thaum tso.
• Zoo tuav nrog puag.
• Kuj zoo li cov tsos ntawm cov nrib pleb - yog ua tiav vim yog ib qho tsis muaj zog shrinkage thaum ziab.
• Cov kev coj tsis zoo - loj yuav tsum tsis ua cov lumps.
• Cov xim dawb - ib qho ntxoov ntxoo tuaj yeem lo hauv qab cov xim xim. Kev sib nrauj nyob rau saum npoo tsis pub.

Yuav ua li cas xaiv cov putty tiav nyob rau hauv kev tha xim

Txhawm rau kom ceev cov haujlwm ua haujlwm, koj tuaj yeem siv cov neeg sib nrauj tas sib nrauj hauv dej. Nws tsis yog qis dua rau cov khoom qhuav. Tsuas yog rho tawm yog tias nws tsis yooj yim sua kom ua tsawg dua yas, tab sis nws yuav tsim nyog tsuas yog rau cov kws tshaj lij uas tau ua haujlwm tau ua haujlwm nrog kev sib xyaw ua ke ntawm ib qho kev sib xws. Rau ib tug pib, qhov no yog tsis zoo li yuav ua qhov tseem ceeb.

Cov khoom cuam tshuam rau cov khoom tseem ceeb los ntawm cov khoom siv yog tsim. Gypsum, Maas thiab polymer sib xyaw muaj. Txhua ntawm cov tsiaj no tuaj yeem siv rau txhua yam kev mob, tab sis qee qhov ntawm lawv yog qhov tsim nyog dua rau cov chaw qhuav kom qhuav. Nws yog qhov nyuaj heev los ua qhov kev xaiv, vim tias cov khoom zoo nyob tsis yog tsuas yog nyob rau ntawm kev sib xyaw, tab sis kuj yog los ntawm cov khw.

Yog tias cov cuab yeej tau xam rau ib hom nto tshwj xeeb, nws tau tso tawm ntawm pob.

Gypsum

Gypsum tiav Putty yog siv, raws li txoj cai, nyob rau hauv cov chav qhuav, raws li cov plaster yog ntshai dej thiab swells thaum nws nkag tau sab hauv. Cov roj pleev xim tsim cov yeeb yaj kiab tiv thaiv nyob rau saum npoo, los ntawm cov dej noo yog qhov nyuaj rau nkag mus, tab sis qhov kev tiv thaiv no yuav tsis txaus. Ib qho ntxiv, xim tuaj yeem yog cov chaw cais. Rau tib lub laj thawj, kev tso pw yog qhov zoo dua los tsim hauv cov chav qhuav - chav lossis kev hauv tsev.

Cov khoom siv tau sai sai. Pov kom muaj tshwm sim hauv peb caug feeb, tom qab ntawd qhov sib xyaw ua tsis haum rau kev thov ntxiv. Lub sijhawm no tej zaum yuav tsis muaj txaus los ua haujlwm tawm tag nrho cov tshuaj, yog li nws yog qhov zoo dua rau yug nws nrog me me.

Ntawm cov txiaj ntsig yuav tsum tau sau tseg:

• Lub zog tsis muaj zog thaum ziab thiab, vim li ntawd, qhov tsis muaj cov kab nrib pleb ntawm ntug;
• tsis muaj tshuaj lom neeg;
• Hluav Taws Kub Kuj - Gypsum tsis kub thiab nyob hauv qhov hluav taws kub tiv thaiv kev kis tus nplaim;
• Cov nplaum zoo cov khoom lag luam.

Maas Mix

Nws yog tsim los ntawm txoj hauv paus ntawm qib 400 thiab 500, uas muaj cov tshuaj lom ntau tshaj plaws. Qhov no ua rau muaj qhov tob tseem ceeb thaum chaw teeb tsa, uas yog them nyiaj rau kev hloov pauv ntxiv.

• Cov khoom mus zoo ntawm lub hauv paus thiab dries qeeb dua cov plaster.

Polymer

Cov ntawv xaus polymer putty yog tus cwj pwm siab tshaj plaws thiab kev sib xyaw ua ke, yog tias koj xaiv qhov nruab nrab zoo nkauj thiab polymer nruab nrab zoo, nws zoo dua los xaiv thawj tus. Cov ntaub ntawv sib xyaw raws li acrylic thiab latex.

Cov txiaj ntsig:

• Thaum lawv tau siv, cov nplaim taws tig mus rau smoother.
• Tsis muaj shrinkage. Vim yog cov cuab yeej no, cov kab nrib pleb tsis tshwm sim vim qhov tsis muaj kev cuam tshuam.
• Ua tsaug rau kev txhim kho cov nplaum nplaum nplaum, muaj kev sib tsoo zoo tshwm sim.
• Cov polymers tsis plam lub cev me txawm tias thaum khov, yog li ntawd lawv tsis tau rhuav tshem thaum poob siab thiab tsis tshwm sim thaum sib txhuam.
• Cov txheej yog fireproof - nws tsis hlawv thiab tsis tso cov tshuaj lom lom ntawm cov tshuaj lom thaum kub.
