Cov kev sib tw tau tsim tus kheej tsis ntev los no, thaum pib ntawm 19th caug xyoo. Tab sis lawv tau dhau los ua qhov kev nyab xeeb tiag tiag tsuas yog tom qab muaj ntau qhov kev sim rau ntawm cov khoom hluav taws xob muaj pes tsawg leeg. Ntau yam khoom siv kuj tseem tau sim dhau ntau caum xyoo rau cov nyom uas cov tshuaj sib tov sib xyaw thov. Nws muab tawm tias tsis yog txhua tus ntoo yuav siv tau hauv kev tsim cov khoom sib tw.
Dab tsi ntoo yog qhov ua tau los
Lub hauv paus txwm ntawm kev sib phim yog cov khoom ntoo, hu ua quav cab hauv kev paub lus. Nws muaj qhov ntev li ntawd uas nws yooj yim los tuav qhov ntais ntawv hauv koj txhais tes. Ib lub taub hau yog thov rau qhov kawg ntawm tus pas, uas muaj cov sib xyaw ntawm cov tshuaj xaiv tshwj xeeb uas tau zoo tshaj plaws kom tau txais txawm tias nplaim taws.
Hauv chav kawm ntawm ntau cov kev sim, nws tau pom tias aspen yog cov khoom siv zoo tshaj plaws rau kev ua lub hauv paus ntawm kev sib xyaw. Nws cov ntoo muaj homogeneous qauv, nws yooj yim los txiav hauv txhua qhov kev taw qhia. Aspen cov xaum yuav muab tau yooj yim cais ua tej daim. Cov ntoo no tseem nqus thiab tuav cov tshuaj lom neeg kom zoo.
Aspen qhov yuam kev tsis muab soot, hlawv nrog ib tug txawm nplaim taws, thiab yog heev nplaim taws. Qhov twg aspen tsis tshua muaj, lwm cov ntoo nrog cov khoom sib xws tau siv, xws li alder, poplar, linden lossis birch. Tab sis ntoo thuv thiab spruce tsis haum rau kev tsim cov khoom sib tw: lawv cov ntoo zoo tuaj yeem tuaj yeem ntes hluav taws thaum cov khoom siv qhuav, thiab cov ntais ntawv hlawv nrog lub nplaim tsis ncaj.
Yuav ua li cas thiaj muaj kev sib tw tau
Cov khoom siv rau kev tsim khoom ntawm lub hauv paus pas nrig yog tua tau, raws li txoj cai, hauv lub caij ntuj no. Nyob rau lub sijhawm no, cov ceg ntoo muaj qhov noo noo haum tshaj plaws. Cov ntoo yog freed los ntawm cov ceg, sawed rau hauv cav thiab xa mus rau lub Hoobkas phim. Ntawm no, cov lus tsis txaus siab tau ua tib zoo txheeb, tsis lees txais cov qauv uas tsis haum cov qauv.
Cov nplaws nws tus kheej yog tsim ntawm veneer, uas tau muab tshem tawm nrog ib txheej nyias los ntawm lub cav nrog rab riam ntev. Ua li no, ib lub tsev ntoo ntawm ob sab yog clamped los ntawm qhov kawg ib feem thiab nqa mus rau hauv kev sib hloov. Ib rab riam ntse, uas tau nqa mus rau qhov chaw ua haujlwm, tshem tawm ib txheej nyias hu ua veneer los ntawm aspen thaiv hauv qhov teeb meem ntawm ob peb feeb. Los ntawm sab nraud, txoj kev no zoo ib yam nkaus li nrawm nrawm nrog daim ntawv tuab tuab.
Hauv kauj ruam tom ntej, lub aspen veneer yog txiav hauv qhov kev hloov pauv thiab qhia tau ntev. Qhov tshwm sim yog straws - zoo tib yam nyias nyias, uas yog los ua lub hauv paus rau yav tom ntej kev sib tw. Tam sim no cov workpieces yog impregnated nrog cov tebchaw tshwj xeeb uas tiv thaiv kom txhob muaj pa. Tom qab txoj haujlwm no, cov quav tau ntim rau hauv lub nruas, qhov uas lawv tau polished, sib cuam tshuam nrog txhua lwm.
Tom qab kev sib tsoo tag nrho, lub hauv paus ntawm yav tom ntej sib luag yuav luag npaj. Kev tsim tawm ntxiv tom ntej pib, uas suav nrog tus lej ntawm cov txheej txheem thev naus laus zis nyuaj thiab cov txheej txheem tshuaj. Raws li qhov tshwm sim, cov ntais ntawv paub sib paub tau yug los, yog li yuav tsum muaj hauv lub neej txhua hnub.
