Cov kws tshaj lij pom zoo kom siv lub npog ntsej muag thaum sau thiab lwm cov kev ua tiav. Cov khoom siv no muaj peev xwm ntxiv dag zog rau saum npoo thiab ua kom lub neej ntawm qhov ua tiav.
Cov xim muaj hlau nqa yog dab tsi?
Daim duab xaj xim kuj tseem hu ua "serpyanka". Nws yog cov ntaub nrog cov xaim xaim ntawm 2x2 hli (lossis ntau dua), ua los ntawm fiberglass impregnated nrog compound tiv taus alkalization. Sab nraud, serpyanka zoo li daim ntaub qhwv lossis cov ntaub nyias nyias. Cov ntaub ntawv no yog siv ua cov khoom txhawb ntxiv rau txhaws thiab plastering phab ntsa. Nws tuaj yeem nplaum tawm rau txhua qhov chaw: ua haujlwm hauv av, ua vaj tse, pob zeb, phab ntsa, fiberboard, chipboard, OSB, thiab lwm yam. Cov khoom ntawm serpyanka no ua rau nws muaj peev xwm siv nws hauv kev ua haujlwm sab nraud thiab sab hauv.
Qhov ntsuas tau zoo ntawm lub mesh yog nws lub zog tensile. Cov yam ntxwv no yog txiav txim siab los ntawm qhov loj ntawm serpyanka mesh thiab tuab ntawm lub fiberglass los ntawm qhov uas nws tau ua. Koj tuaj yeem yuav nws nyob txhua lub tsev muag khoom uas muag cov khoom tsim tsev.
Npaum li cas thiab nyob qhov twg cov xim nqa tau siv?
Thaum ua tiav ntawm kev ua haujlwm, yeej ib txwm muaj kev xav ua kom lub zog ntawm plaster txheej. Rau qhov no, lub ntsej muag looj ntsej muag yog siv. Nws yuav tsum tau nyob ntawm cov khaubncaws sab nraud povtseg, uas yog lub phab ntsa yog qib.
Kev siv serpyanka yog qhov yuav tsum tau ua hauv cov xwm txheej nram qab no: thaum ua tiav qhov rai thiab lub qhov rooj; thaum kev sib khi dav thiab sib sib zog nqus; ntawm qhov kev sib tshuam ntawm cov canvases ntawm cov khoom siv los ntawm kev uas cov phab ntsa ua (piv txwv, phab ntsa ntub dej); ntawm fab; yog tias muaj qhov dhau ntawm cov xuab zeb lossis cov cement, qib ntawm cov uas qis dua qhov yuav tsum tau ua, hauv kev sib xyaw ntawm cov cement-sand mortar; yog tias muaj cua sov nyob hauv chav. Daim duab xim yuav txhim kho lub adhesion ntawm txheej ntawm cov tshuaj kom tiav, mus rau ntawm seem ntawm lub nra, thiab nce lub zog ntawm cov khoom npog.
Ua raws li qhov loj ntawm lub hlwb, tus yam ntxwv thiab kev ua haujlwm ntawm serpyanka yuav txawv. Nws tuaj yeem siv thaum nteg cov vuas vov, ua haujlwm thermal rwb thaiv tsev ua haujlwm, kom cov chaw tsis muaj zog thaum rov qab kho dua, thaum rov ua kom lub tsev ruaj khov, thiab txhim kho lub ru tsev.
Serpyanka yog pw hauv ob txoj kev. Yog hais tias lub zog ntawm lub hauv paus tso cai, daim npog ntsej muag yog nplaum rau PVA kua nplaum (lossis lwm yam khoom siv tiv thaiv kev ya raws), ncab, ncab. Tom qab cov nplaum lo tau qhuav, ib txheej ntawm plaster yog thov dua lub serpyanka. Nws pom tias nws nteg qis dua tusyees ntawm daim phiaj xim.
Thaum ua qhov kev ua hauj lwm putty lossis plastering, serpyanka yog txuas rau txheej txheej ua ntej ntawm cug. Cov kab xev fiberglass yuav tsum qis me ntsis mus rau hauv nws, tab sis tsis chwv lub hauv paus ntawm phab ntsa. Yog tias koj xav ua cov tuab tuab plaster txheej (piv txwv li, thaum leveling nto), nws pom zoo kom nteg ob peb txheej ntawm serpyanka.
