Beech yog ib hom ntoo ntau tshaj plaws uas pom muaj nyob hauv cov hav zoov sib xyaw thiab deciduous thoob plaws ntau lub tebchaws Europe. Nws yog dav siv nyob rau hauv kev tsim cov rooj tog. Nws cov ntoo muaj lub zog zoo, toughness thiab inelasticity. Qhov ceev ntawm beech, uas yuav tau tham nyob rau hauv tsab xov xwm, nyob ntawm seb lub cellular qauv thiab humidity.

Yuav ua li cas yog qhov ntom ntawm ntoo?

Tus nqi no hu ua qhov piv ntawm huab hwm coj mus ntim. Nws tsis tas li thiab nyob ntawm cov av noo ntawm ib puag ncig uas cov khoom nyob. Qhov loj dua qhov loj ntawm ib cubic meter ntawm ntoo, qhov denser nws yog. Yog li ntawd, nws yog kev cai siv qhov tseem ceeb uas sib haum rau cov av noo ntawm 12%. Nws yuav tsum nco ntsoov nco ntsoov tias qhov ntom ntawm beech lossis lwm yam ntoo yog kwv yees. Qhov no yog vim qhov tseeb tias txawm tias tib daim ntoo hauv cov huab cua sib txawv yuav muaj qhov sib txawv.

Tus nqi no muaj kev cuam tshuam ncaj qha rau lub zog thiab hygroscopicity ntawm ntoo. Ib qho piv txwv zoo: lub qhov rooj rau da dej yog ua los ntawm linden, aspen los yog ntoo thuv, raws li beech yuav cias kaw. Beech ntom nyob rau hauv g / cm3 yog li ntawm 0.65 mus rau 0.9 thiab nyob ntawm seb ib puag ncig tej yam kev mob nyob rau hauv uas cov khoom los yog cov khoom nyob rau hauv.

Ncej ntoo beech

Beech hu ua niam ntawm hav zoov vim nws pab lwm cov ntoo tawv kom ciaj sia thiab ciaj sia. Cov dej nag uas ntws los ntawm cov ntoo ntawm beech ntoo muaj kev cuam tshuam rau cov nroj tsuag uas deplete cov av. Lub voluminous crown tiv thaiv evaporation ntawm noo noo thiab ziab ntawm cov av, thiab ib tug loj npaum li cas ntawm poob nplooj nyob rau hauv lub caij nplooj zeeg ua ib tug as-ham txheej ntawm humus. Qhov siab ntawm tsob ntoo qee zaum ncav cuag 45 meters nrog ib txoj kab uas hla tshaj ib 'meter'. Ncaj-grained ntoo muaj ib tug nplua thiab txawm qauv, thaum beech ntoo ntom thiab hardness nyob ntawm qhov chaw ntawm kev loj hlob. Nws tau sau tseg tias pob zeb los ntawm Northern Europe, Denmark thiab UK yog qhov nyuaj thiab hnyav dua li ntawm Romania, Yugoslavia thiab Central Europe.

Technological khoom ntawm beech

Highlight khoom xws li:

• Lub peev xwm tuav cov hlua khi ua los ntawm cov hlau - perpendicularly nkag mus rau hauv ntoo, tus ntsia thawv txiav qee cov fibers, thaum lwm tus txav sib nrug thiab tuav cov hlau fastener. Cov dej noo ntawm cov ntoo ua rau nws yooj yim dua rau rauj, tab sis thaum nws qhuav, beech lub peev xwm tuav tau tus ntsia thawv txo.
• Muaj peev xwm khoov - zoo rau kev ua kom sov, hloov tau yooj yim, yog li nws yog siv los ua rooj tog khoov rau cov chaw ua haujlwm thiab thaj chaw nyob.
• Hnav tsis kam - tus nqi nruab nrab ntawm beech ntom hauv kg / m3sib npaug rau 680, yog li cov ntoo muaj lub zog siab thiab tiv taus cov neeg kho tshuab siab. Boards raug pom zoo rau cov plag tsev thiab cov ntaiv.
• Splitting kuj - muaj me ntsis tsis kam rau kev sib cais ntawm cov qauv thaum lub npoo yog ntxig rau hauv cov kev taw qhia ntawm cov fibers, thiab nyob rau hauv lub radial kev taw qhia nws yog tsawg tshaj li nyob rau hauv lub tangential kev taw qhia. Cov khoom siv tau yooj yim ua tiav nrog cov cuab yeej tes, sawn thiab pricked.

Beech ntoo tuaj yeem ua tiav: sanded, polished thiab khoov. Ntoo yog yooj yim glued, zoo stained nrog dyes.

Qhov zoo thiab qhov tsis zoo ntawm beech

Qhov zoo yuav tsum suav nrog:

• siab ductility thiab yoog raws;
• xav txog lub zog, vim qhov ntom ntawm beech tsis qis dua rau tib qhov kev txwv ntawm ntoo qhib;
• muaj peev xwm tiv taus qhov nrawm;
• original texture;
• muaj peev xwm rov pleev xim thiab tshuaj dawb;
• tshuaj tiv thaiv kab mob.

Flaws:

• khoom tsis zam huab cua qhuav, tuaj yeem tawg;
• ntoo tsis haum rau ua rooj tog hauv chav dej, da dej, saunas, vim nws tuaj yeem rot;
• khoom siv beech hnyav heev;
• Lub hnub ncaj qha yuav hloov xim ntawm cov khoom.

Thaum npog cov khoom nrog cov kua roj vanish lossis xim, ntau yam teeb meem tuaj yeem zam tau.

Quality beech and oak wood

Beech thiab ntoo qhib yog tib tsev neeg, tau muab faib ua ntau yam thiab zoo sib xwskhoom. Ob hom ntoo yog tus cwj pwm los ntawm kev loj hlob qis, thiab qhov ntom ntawm beech thiab ntoo qhib yog ze rau tus nqi. Rau ntoo qhib, qhov taw qhia yog 690 kg/m3. Lawv qhov txawv feature yog siab zog thiab hardness. Cov ntoo ntawm ob qho tib si ntoo qhib thiab beech muaj qhov zoo, zoo nkauj zoo nkauj thiab tsis muaj pob, yog yooj yim stained thiab zoo kawg nkaus ua tiav los ntawm cov cuab yeej siv ntoo. Lub siab hnav tsis kam ntawm pob zeb tso cai rau lawv siv rau hauv kev tsim kho hauv pem teb, cov kauj ruam thiab cov rooj tog tsim khoom.

Nws tau sau tseg tias nyob rau hauv lub zog ntawm chav, beech tau txais cov cuab yeej ntawm kev khoov, thiab stains tau txais lub zog ntau dua thiab ua rau tsaus dua. Beech, tsis zoo li ntoo qhib, dries sai sai, yooj yim rau xuab zeb thiab adheres zoo. Tab sis ntoo los ntawm nws yog raug rau cov kab mob fungal thiab pwm, thiab kuj absorbs dej ntau zog tshaj ntoo qhib. Elegant beech nrog sov thiab mos lub zog refreshes lub sab hauv kho kom zoo nkauj ntawm chav tsev, thiab ntoo qhib tsim discreet khoom kim heev, muab nobility thiab aristocracy.

Beech application

Beech ntoo muaj txiaj ntsig zoo: tsis muaj ntxhiab tsw, khoov zoo, zoo kawg nkaus tuav cov ntsia hlau (cov rau tes thiab cov ntsia hlau), tsis yooj yim rau warping thiab tawg. Nrog rau qhov nruab nrab ntom ntom, beech muaj lub zog siab thiab ua tiav zoo kawg nkaus. Yog li ntawd, nws yog siv los ua:

• rooj tog thiab pem teb;
• sliced veneer;
• tais, txiav boards, pob tawb, thoob;
• musical instruments;
• raw khoom rauacetone, methyl cawv;
• tshuaj raw khoom.

Qhov tsis zoo ntawm beech ntoo yog nws qhov nqus dej noo, yog li tiv thaiv cov khoom, lawv yog varnished thiab ntau yam impregnating agents.

Qhov zoo sib xws ntawm beech thiab birch

Birch board muaj nuj nqis rau nws cov tsos. Nws ntseeg tau tias tsob ntoo no tsis muaj cov noob, yog li ntoo tsuas muaj sapwood thiab muaj cov xim daj-dawb lossis pinkish xim. Nws muaj nuj nqis rau nws cov fibers sinuous uas tsim cov kev ntxhib los mos zoo nkauj, uas yog vim li cas birch siv los ua cov khoom siv kho kom zoo nkauj. Cov txiaj ntsig ceev ntawm beech thiab birch yog ze rau ib leeg. Lub tom kawg muaj qhov ntsuas ntawm 650 kg / m 3, uas tso cai rau nws siv los ua rooj tog. Nws kuj tseem qiv nws tus kheej zoo rau kev ua, tab sis, dua, cov av noo siab yuav tsum raug coj mus rau hauv tus account.

Cov khoom uas nyob ntawm txoj kev sai sai npog nrog pwm thiab rot. Tsis tas li ntawd, cov khoom yuav raug shrinkage mus txog 8%. Birch plywood yog tshwj xeeb tshaj yog muaj nqis. Cov neeg ua haujlwm hauv tsev ua cov txee, cov coasters carved thiab lub teeb rooj tog los ntawm nws. Qhov tseem ceeb tseem ceeb yog qhov siab thermal conductivity ntawm ntoo thiab tso tawm ntau cov cua sov thaum combustion.

Zaj lus

Nrog cov khoom zoo sib xws hauv qhov ntom ntom, hardness thiab hnav tsis kam, birch, beech thiab ntoo qhib tau dav siv hauv kev lag luam rooj tog. Rau kev xaiv peev nyiaj, birch yog tsim nyog; rau kev xaiv kim dua, nyiam yog muab rau beech lossis ntoo qhib, uas yuav luag tib lub zog thiab sib txawv xwb.qauv.
