Txhua leej txhua tus paub tias kev raug puas tsuaj dab tsi ua rau muaj hluav taws. Yog li, kom khaws cov khoom muaj nuj nqis, thiab, ua ntej txhua yam, los tiv thaiv tib neeg lub neej, nyob rau tej qhov chaw uas neeg sib sau ua ke (piv txwv li, nyob rau hauv cov chaw lag luam lossis chaw ua haujlwm hauv chav nyob), nws raug nquahu kom lub qhov rooj hluav taws qhov rooj.
Hluav taws tua hluav taws tua hluav taws
Txij li cov hauj lwm ntawm lub qhov rooj xws li thaiv qhov hluav taws xob nkag mus rau hauv ib qho chaw thiab kom muaj kev cuam tshuam rau ntau lub sij hawm, qhov tseem ceeb ntawm cov qhov rooj ntawm hom no yog kev siv cov khoom tsis ua rau lawv cov khoom.
Raws li txoj cai, high-quality steel yog siv los ua qhov rooj nplooj ntawm qhov cub hluav taws. Lub qhov rooj sab hauv ntawm lub qhov rooj (nyob rau hauv txoj kev ua kom lub qhov rooj zoo li ib lub thawv) muaj cov ntaub ntawv tshwj xeeb refractory uas tiv thaiv los ntawm cua kub thiab hlawv nws tus kheej. Uas yog, txawm tias qis tshaj ntawm qhov hluav taws kub, qhov rooj tsis deform, yuav tsis muaj kev hloov hauv txoj cai ntawm nws txoj kev qhib thiab kaw. Ntawm cov khoom siv tshwj xeeb uas tsis kub thiab tsis zom thaum raug mus rau high kub, saib xyuas tau ua rau hluav taws qhov rooj. Thiab lub mechanism ntawm lub qhov rooj saib xyuas yog xws li hais tias, yog tias tsim nyog, lawv yuav yooj yim qhib txawm tias ib tug me nyuam me los yog ib tug laus zog txiv neej. Nyob sab nraum zoov, lub qhov cub hlau raug thaiv nrog cov xim tshwj xeeb hluav taws-polymer-hmoov xim.
Rau qhov zoo nkauj tshaj plaws, qhov rooj xws li tuaj yeem ua kom muaj ntau yam ntaub ntawv, piv txwv li, ntoo. Ntawm chav kawm, nyob rau hauv cov ntaub ntawv ntawm ib qhov hluav taws kub, tag nrho cov zoo nkauj ntsiab yuav ploj, tab sis qhov tseem ceeb hauv qhov chaw yuav khaws cia.
Nrog rau txhua yam tsim nyog rau kev tsim hluav taws xob tsim hluav taws qhov rooj thiab, nyob ntawm tus qauv tsim, lawv (qhov rooj) muaj peev xwm tiv tau qhov teeb meem ncaj qha ntawm hluav taws rau 30 mus rau 90 feeb. Hais txog kev tsim kho ntawm qhov rooj.
Hom hluav taws kub qhov rooj
Nyob ntawm cov leaflets (canvases), hluav taws kub qhov rooj raug muab faib ua ob hom - ib-teb thiab ob-daim teb. Kev ua haujlwm thiab ua haujlwm zoo yog qhov zoo tib yam rau lawv, nrog qhov sib txawv ntawm qhov tsuas yog qhov pom ntawm qhov loj loj, ob lub qhov rooj ntawm ob lub hnab muaj nqi ntau dua.
Tsis tas li ntawd nws yuav tsum tau hais tias qhov ob-nplooj ntoos qhov cub hlau tau ua nyob rau hauv xws li ib txoj kev uas lub qhov rooj (canvases) qhib rau hauv ib txoj kev (ib qho tseem ceeb ntawm cov cai tswj kev tiv thaiv hluav taws). Ob lub qhov rooj ntawm qhov rooj, nyob ntawm qhov sib txawv ntawm qhov dav ntawm ib nplooj ntoos mus rau qhov dav ntawm lwm nplooj, tuaj yeem sib npaug los yog txawv. Kev txhim kho ntawm qhov no los yog hom qhov hluav taws kub tiv thaiv yog los ntawm, ua ntej txhua yam, los ntawm qhov ntau thiab tsawg ntawm qhov rooj thiab lub sijhawm teem ntawm lub tsev.
Raws li txoj cai, ib lub qhov rooj qhib lub qhov rooj raug ntsia hauv cov chaw, cov chaw siv hluav taws xob lossis cov chav ua haujlwm. Lub qhov rooj ob-qhov hluav taws kub qhov rooj feem ntau ntsia nruab nrab ntawm cov khw muag khoom loj nrog cov tsheb loj thauj neeg. Nws yog tus yuav tsum tau ua kom tiav ib qho kev lag luam ntawm ob leeg ib zaug thiab ob lub qhov cub hluav taws kub, qhov tshwj xeeb yuav muab siv, uas yuav tiv thaiv kom txhob kis tau cov khoom sib txuas ua ke rau hauv chav. Tsis tas li ntawd nws yuav tsum tau hais tias muaj kev xaiv rau kev txhim kho glazed (glazing yuav ua tau li ntawm 25% ntawm qhov rooj ntawm nplooj qhov rooj) ntawm ob hom ntawm qhov rooj hluav taws. Ua ib qho ntxig rau qhov no, siv lub iav tshwj xeeb muaj zog ua kom muaj zog.
