Cov ntoo ntawm cov ntoo txiav ntev-lub siab no yog cov tsiaj tsis tshua muaj nqi. Kab lus yuav txiav txim siab ntau yam ntawm cov laug cam ntoo thiab lawv daim ntawv thov. Txawm hais tias qhov tseeb tias lawv cov nqi raug siab heev, cov nqi raug lees paub los ntawm kev ua haujlwm ntev ntawm cov khoom lag luam ua los ntawm cov khoom ruaj thiab ntxim nyiam.
Peculiarities
Beech yog tsob ntoo zoo li tsob ntoo txiav ntoo uas yog ib qho ntawm ntau hom hav zoov nyob hauv Europe . Mus txog thaj tsam ntawm Ukraine thiab thaj av Crimean, nws tseem nthuav mus rau ntug dej hiav txwv ntawm Dej Hiav Txwv Atlantic, nthuav dav mus rau Gulf of Finland.
Tsob ntoo beech muaj lub cev du thiab siab, qhov siab uas tuaj yeem ncav cuag 35-40 m. Cov ntoo beech zoo nkauj yog qhov tsis tshua ntev-lub siab, nws lub sijhawm loj hlob tuaj yeem yog ntau dua 400 xyoo. Xws li txheej txheem lub neej ntev tau piav qhia los ntawm qhov tseeb tias tsob ntoo no loj hlob qeeb heev.
Raws li cov khoom siv raw rau kev tsim cov ntoo, ntoo ntoo tawv ntoo tau sau los ntawm tsob ntoo hnub nyoog yam tsawg 50 xyoos.
Cov laug cam ua los ntawm beech muaj qib siab ntawm lub zog, hloov pauv thiab ua haujlwm ntev . Txawm li cas los xij, ntoo tuab tsis zam cov dej noo zoo. Los ntawm lawv cov qauv, cov fibers ntawm cov pob zeb txiav ntoo no muaj qib siab ntawm hygroscopicity thiab cia nqus cov dej noo ntau tshaj los ntawm huab cua. Kev nqus dej noo ua rau qhov tseeb tias cov khoom ntoo pib deform thiab rot. Muab qhov tshwj xeeb ntawm cov ntoo hauv cov lus nug, nws tau siv tsuas yog rau kev ua tiav sab hauv.
Nyob rau hauv qhov tsos, qhov pom txiav ntawm tsob ntoo beech muaj xim dawb nrog xim liab-xim daj.
Nyob rau hauv qhov cuam tshuam ntawm cov pa, ntoo txiav dhau sijhawm hloov nws cov xim rau xim liab-xim av. Los ntawm nws cov qauv, ntoo yog tuab heev thiab hnyav, thiab yog tias cov khoom siv raug rau txheej txheem kom qhuav sai, tom qab ntawd nws pib tawg thiab deform . Cov ntoo beech ntoo zoo-qhuav muaj qhov ua ntej rau txheej txheem yooj yim ntawm kev ua thiab tom qab txhuam cov khoom tiav.
Raws li tau hais dhau los, ib yam khoom ntawm beech yuav tsum siv tsuas yog sab hauv tsev, txij li thaum qhib huab cua cov khoom no sai heev nqus dej noo thiab rots.
Lub cev tseem ceeb ntawm cov ntoo no yog:
- khoom ntom ntom - 500-900 kg / m³;
- thermal conductivity - 0.17 W / (m * K);
- lub zog tensile - 136 N / mm2;
- qib ntawm kev sib zog - 60 N / mm2;
- qib ntawm dabtsi yog khoov zog yog 120 N / mm2.
Cov xim daj-xim paj yeeb ntawm cov ntoo beech nyob rau hauv cov xwm txheej ntawm kev ua haujlwm nrog cov cua kub tuaj yeem hloov nws cov xim rau xim av xim liab, uas zoo li zoo nkauj thiab zoo nkauj.
Ntoo beech ntoo tsis muaj ntxhiab kiag li thiab lub zog ntawm cov khoom siv feem ntau zoo dua rau cov ntoo ntoo xws li birch, cherry lossis hornbeam.
Lub siab ntev-siab nrog cov ntoo zoo nkauj tuaj yeem loj hlob ob qho tib si hauv toj roob hauv pes thiab hauv hav zoov. Qhov ncaj thiab txawm tias lub cev ntawm tsob ntoo no ntawm kev txiav, ua nyob rau hauv txoj kev hla mus, muaj cov qauv zoo nkauj ntawm cov nplhaib ib xyoos ib zaug, uas tau nyob ze ib leeg.
Tab sis yog tias koj piv beech nrog ntoo qhib, ces beech ntoo poob mus rau qhov loj nyob rau hauv cov nqe lus ntawm nws cov durability thiab tsis kam mus rau lwj.
Beech ntoo nqus tau txhua hom zas xim zoo, nws cov xim tuaj yeem hloov pauv siv cov thev naus laus zis thev naus laus zis, ntxiv rau pleev xim nrog cov kua roj vanish.
Hom kev txheeb xyuas
Cov ntoo beech uas muaj nqis raug txiav los ua cov phiaj xwm zoo los yog cov laug cam uas tsis tau tawg. Beech raw cov ntaub ntawv tau siv los ua veneer, veneer plywood qhuav, thiab rooj tog zaum.
Ntoo Beech, nyob ntawm nws hom, pom nws tus kheej hauv ntau yam kev thov
Rooj ntug - cov khoom qub uas tsis muaj ntaub ntawv yog ua tib zoo tsis kam, qhuav thiab yuav tsum tau ua tiav nrog tshwj xeeb impregnating tiv thaiv kev tiv thaiv. Ua tsaug rau qhov no impregnation, ntoo khaws nws cov xim xim thiab dhau los ua qhov tsis yooj yim rau nqus dej. Cov khoom siv yog siv rau kev tsim cov khoom hauv pem teb, staircases, ua kom tiav cov vaj huam sib luag thiab cov laug cam tau ua los ntawm nws, cov rooj tog hauv txee tau sib sau ua ke, siv los ua kev kho kom zoo nkauj sab hauv hauv daim ntawv ntawm phab ntsa vaj huam sib luag. Cov tuab ntawm cov khoom tuaj yeem yog 10 txog 50 hli.
Pawg thawj coj saib tsis tau - Qhov seem ntawm beech raw cov ntaub ntawv tsuas yog ua tiav raws qhov dav ntawm lub phaj, thaum cov tawv ntoo tseem nyob ntawm ob sab. Cov khoom siv no yog qee yam pheej yig dua li cov khoom sib xyaw thiab tau siv rau sab hauv sab hauv ntawm sab hauv tsev.
Rooj tog rooj tog - feem ntau nws tau siv cov ntoo veneers ntawm ntau qhov tuab thiab xaiv txiav kaum. Qhov kom zoo dua ntawm cov khoom siv no yog nws cov qauv zoo nkauj, uas yog siv rau kev kho kom zoo nkauj sab hauv lossis hauv kev tsim cov rooj tog hauv tsev.
Kev siv sab hauv tsev ntawm beech yog qhov ncaj ncees los ntawm nws lub zog ntuj thiab cov khoom zoo nkauj zoo nkauj.
Cov cheeb tsam ntawm kev siv
Txawm hais tias tus nqi siab ntawm cov khoom siv, ntoo beech muaj qhov xav tau siab thiab ntau yam kev siv. Beech yog siv rau ntau lub hom phiaj.
Rau kev npaj cov hauv pem teb hauv chav ntoo zoo nkauj yog siv los ua cov khoom tiav. Rau lub hom phiaj no, lub rooj sib tham parquet zoo thiab kim yog tsim los ntawm cov ntoo ntoo, uas ua rau pom tseeb tus nqi los ntawm kev tiv taus cuam tshuam thiab puas.
Hauv thaj chaw nyob nrog cov tsheb qis, beech tau siv rau kev tsim cov qauv tshwj xeeb ntawm sab hauv cuam tshuam nrog ntaiv … Cov khoom lag luam zoo li no yog qhov kho kom zoo nkauj zoo nkauj nyob rau sab hauv ntawm txhua lub tsev.
Thaum kho nrog cov pa kub, beech muaj peev xwm hloov tau yooj yim heev … Cov nyhuv no yog siv hauv kev tsim cov rooj tog zaum vintage thiab cov cuab yeej siv suab paj nruag.
Nyias beech veneer tuaj yeem ua xim zas xim rau ntau yam xim thiab siv rau kev tsim cov duab mosaic zoo nkauj . Cov ntoo pov tseg ntawm tsob ntoo ntoo txiav ntoo no yog siv hauv kev lag luam tshuaj hauv kev tsim cov tshuaj methyl cawv, tar lossis roj creosote .
Cov khoom siv beech tau txais txiaj ntsig rau nws cov khoom zoo nkauj, yog li ntawd nws siv kuj yog qhov ncaj ncees hauv kev tsim khoom plig khoom plig .
Lub ntuj tuab ntxhib los mos ntawm beech ntoo fibers ua rau nws ua tau kom cov khoom los ntawm nws tom hniav sib tsoo, ua tsaug rau uas koj yuav cuag ib txig du thiab txawm nto.
Beech khoom rau txhua lub hom phiaj yuav tsum tau tiv thaiv los ntawm ya raws.
Rau lub hom phiaj no, ntoo tau pleev xim nrog cov tshuaj tsis haum dej thiab npog nrog txheej tiv thaiv cov kua roj vanish. rau lub hom phiaj no, ntoo tau pleev xim nrog cov tshuaj tiv thaiv dej thiab npog nrog txheej tiv thaiv cov kua roj vanish.
