Plaster khoom muaj peev xwm hloov txhua yam sab hauv, muab nws tus kheej. Tshwj xeeb yog tias lawv tsis tau tsim hauv lub Hoobkas, tab sis ntawm nws tus kheej - raws li koj tus kheej kos duab. Thev naus laus zis rau kev tsim lawv tsis yog qhov nyuaj.
Muaj ob lub hauv paus ntsiab lus ntawm kev txiav txim siab thaum ua koj tus kheej cov khoom lag luam plaster. Thawj yog lub sau. Cov kev xaiv tau yog qhov siv zog, xav tau kev tsim cov qauv ntawm cov qauv (ua cov ntoo, plasticine, av nplaum) thiab lub pwm rau txhawm, tab sis nws tso cai rau koj los tsim cov duab zoo nkauj volumetric. Qhov thib ob txoj kev yog plaster carving. Nws yog qhov tsim nyog dua rau kev tsim cov khoom dai zoo nkauj. Ntawm cov cuab yeej, koj tsuas xav tau kos duab kos duab, ua ib qho txis thiab zoo riam los yog pob taub hau.
Raws li "tus qauv" rau kev tsim cov pwm rau kev sau nrog plaster, koj tuaj yeem siv cov khoom npaj tau uas koj nyiam (piv txwv li, daim duab). Nws yog ua tib zoo lubricated nrog roj av jelly lossis silicone roj thiab muab tso rau ib qho chaw tiaj (npog lossis lwm qhov kev tiv thaiv), lub cev ntoo lossis steel yog tsim nyob ib ncig ntawm nws, uas tseem tau lubricated kom yav tom ntej cov duab tsis lo. Tom qab ntawd plaster tov ntawm qhov sib xws ntawm tuab qaub cream yog poured rau hauv tus ncej, noj mus rau hauv tus account tias qauv yuav raug tshem tawm ntawm cov pwm tom qab ziab.
Yog hais tias tus qauv rau kev tsim daim foos yog tsim los ntawm koj tus kheej, nws yuav tsum muaj zog, qhuav, varnished.
Thaum qhov kev daws teeb meem tau ua tiav, cov qauv coj tawm. Daim ntawv yav tom ntej no tau qhuav huv, qhov tsis xws luag yog neutralized (piv txwv li, pits los ntawm huab cua npuas) siv tib txheej plaster, varnished los ntawm sab hauv. Tom qab cov kua roj vanish tau qhuav, lub pwm npaj txhij ua tiav nrog plaster los tsim cov khoom kawg, tab sis nco ntsoov ntxuav thiab ntub nws ua ntej txhua lub ncuav tshiab. Cov duab ntawm cov duab nyuaj yog feem ntau ua ke los ntawm ntau qhov chaw, ntiab nyias.
Nws yog qhov yooj yim tshaj plaws los sau cov pwm hauv ob theem: thawj, txheej nyias nyias uas ua tiav tag nrho cov kab noj hniav me, tom qab ntawd - qhov feem ntau Yog tias cov khoom loj, nws yuav siv tau los ua kom nws muaj zog nrog ntxiv dag zog. Lub tiav lawm lub cev qiv nws tus kheej zoo mus rau xim. Txog kev ua tiav kawg, nws raug nquahu kom npog nws nrog ib txheej ntawm siv quav ciab lossis kua roj vanish.
Kev pab daim hlau, dai kom zoo nkauj, cov lus tso kom zoo nkauj yooj yim dua rau kev nqa tawm los ntawm carving ntawm plaster.
Txhawm rau tsim cov duab kos ntawm cov khoom piav txog yav tom ntej, koj yuav xav tau cov ntawv kos duab tuab (yog tias cov ntsiab lus rov ua dua, nws yuav yooj yim rau quav nws ob peb zaug). Cov contours ntawm cov qauv yav tom ntej yog kos rau nws thiab cov ntaub qhwv tau ua raws txoj kab ntawm qee qhov deb ntawm lwm tus nrog muaj awl lossis rab koob. Lub thav duab ntawm qhov xav tau loj (txog 3 cm siab) muab tso rau ntawm qhov chaw tiaj tiaj tiv thaiv.
Gypsum yog nchuav ua ob theem. Thawj txheej, txhawm rau pwm los ntawm ob feem peb, npaj rau hauv qhov sib piv ntawm 2 seem ntawm gypsum mus rau 3 seem ntawm dej. Ncuav nws (yam uas tsis tau do) thaum nws kis tau cov khoom qab zib ntawm qaub cream. Qhov thib ob txheej yog npaj nyob rau hauv qhov sib npaug, tab sis kneaded heev kom huv si. Sab qaum yog nchuav 10 feeb tom qab thawj zaug, so cov qhov chaw tawv tawv nrog daim ntaub qhuav.
Tom qab 10-15 feeb, tshem tawm cov cuam tshuam slats, koj tuaj yeem hloov cov qauv mus rau saum npoo ntawm plaster. Txhawm rau ua qhov no, ib daim ntawv nrog cov ntawv punctures yog tusyees tso rau ntawm gypsum dawb paug thiab txau nrog cov xim qhuav (sawv los ntawm lub qhov, nws ua ib qho qauv dotted). Nrog pob taws los yog riam rau ntawm lub plaster, kev txiav yog ua tib zoo ua ib txhij rau tus qauv (nrog qhov tsis poob ntsej muag ntawm 2-3 hli rau qhov "keeb kwm yav dhau"), tom qab ntawv txheej ntawm cov keeb kwm yav dhau los ua tib zoo tshem nrog tib rab riam cov khoom zoo nkauj protrudes.
