Plywood yog qhov xav tau zoo hauv kev tsim kho. Cov ntawv ua los ntawm cov ntoo ntoo muaj lawv tus kheej qhov zoo. Hauv kab lus no, peb yuav ua tib zoo saib cov yam ntxwv tseem ceeb ntawm cov ntoo plywood.

Yam ntxwv

Birch yog cov khoom siv xav tau tshaj plaws hauv kev tsim cov plywood, txij li, tsis zoo li lwm txoj hauv kev, nws muaj qhov zoo hauv qab no:

• qib zoo ntawm lub zog;
• cov dej noo-tiv thaiv cov nyhuv;
• yooj yim ntawm cov txheej txheem ua;
• tshwj xeeb zoo nkauj zoo nkauj ntawm kev ntxhib los mos.

Cov txheej txheem tseem ceeb thaum xaiv cov ntoo plywood yog nws qhov ntom ntom ntom, uas yog 700-750 kg / m3, uas dhau qhov ua tau zoo ntawm cov khoom sib xyaw ua ke. Vim nws qhov ntom ntom ntom ntom ntom ntom, cov nplooj ntoo veneer yog qhov kev xaiv zoo tshaj plaws rau ntau qhov kev txiav txim siab tsim.

Qhov ntsuas tseem ceeb hauv kev npaj yog qhov tshwj xeeb ntawm daim ntawv plywood, txij li thaum siv hauv cov qauv, nws yuav tsim nyog los suav qhov kev cia siab ntawm lub hauv paus txheej txheem yav tom ntej. Qhov hnyav ntawm ib daim ntawv, nrog rau nws qhov ntom ntom ntom, nyob ntawm cov khoom siv hauv paus (cov ntawv ntoo yuav hnyav dua li ib tsob ntoo coniferous). Hom kua nplaum siv tsis cuam tshuam rau qhov tuab ntawm cov plywood.

Qhov ntsuas tseem ceeb yog qhov tuab ntawm daim ntawv plywood . Thaum siv cov khoom siv rau kev ua haujlwm sab hauv (rau kho kom zoo nkauj phab ntsa), siv cov vaj huam sib luag 2-10 hli tuab.

Birch plywood tuaj yeem siv rau txhua qhov xwm txheej huab cua, txij li qis lossis siab kub tsis cuam tshuam rau cov khoom ntawm cov khoom pib.

Cov txheej txheem txuj ci

Raws li GOST, birch plywood tau muab faib ua tsib qib. Qib siab dua, cov pob txha tsawg dua ntawm cov khoom. Xav txog qhov sib txawv ntawm ntau yam.

Qib 1

Qhov tsis zoo rau ntau yam no:

• tus pin, yuav tsum tsis pub ntau tshaj peb daim rau 1 sq. m;
• cov pob txha noj qab haus huv txuas nrog, tsis pub tshaj 15 hli txoj kab uas hla thiab hauv qhov ntau tsis ntau tshaj 5 daim hauv 1 sq. m;
• xa cov pob tw nrog lub qhov, tsis pub tshaj 6 hli txoj kab uas hla thiab tsis ntau dua 3 daim hauv 1 sq. m;
• kaw cov kab nrib pleb, tsis pub ntev tshaj 20 hli thiab tsis ntau tshaj 2 daim rau 1 sq. m;
• puas tsuaj rau ntawm daim ntawv (tsis ntau tshaj 2 hli hauv qhov dav).

Qib 2

Piv rau thawj hom, ntau yam no tso cai rau pom muaj qhov tsis xws luag hauv qhov nyiaj ntau dua 6, cov no suav nrog:

• kev noj qab haus huv zoo dua li 5% ntawm cov ntawv plywood nto;
• sib tshooj ntawm cov khoom ntawm txheej txheej sab nrauv (tsis pub ntev tshaj 100 hli);
• seepage ntawm cov nplaum puag (tsis ntau tshaj 2% ntawm tag nrho cov ntawv hauv cheeb tsam);
• notches, kos, khawb.

Qib 3

Tsis zoo li hom yav dhau los, qhov tsis zoo hauv qab no raug tso cai (yuav tsum tsis pub ntau tshaj 9 ntawm lawv):

• ob chav ntoo ntxig;
• tearing tawm ntawm cov khoom sib xyaw (tsis ntau dua 15% ntawm daim ntawv plywood nto);
• kua nplaum loj ntws tawm (tsis ntau dua 5% ntawm tag nrho cheeb tsam ntawm daim ntawv plywood);
• qhov los ntawm kev tawm pob, tsis pub tshaj 6 hli txoj kab uas hla thiab hauv qhov ntau tsis ntau tshaj 10 daim rau 1 sq. m;
• nthuav cov kab nrib pleb mus txog 200 mm hauv qhov ntev thiab tsis ntau tshaj 2 mm hauv qhov dav.

Qib 4

Ntxiv rau qhov tsis xws luag ntawm qib dhau los, qhov ua tsis tau raws li hauv qab no raug tso cai ntawm no, yam tsis suav nrog qhov ntau:

• wormholes, accrete, ntog tawm pob;
• txuas thiab kis kab mob;
• los ntawm cov nplaum, gouges, khawb;
• rub tawm cov fibrous hais, sib tsoo;
• plaub hau, plaub hau, ripples.

Ntxiv rau qhov saum toj no, muaj qib E siab tshaj, uas yog cov neeg tseem ceeb. Ib qho, txawm tias qhov sib txawv tseem ceeb tsis tuaj yeem lees txais ntawm cov khoom lag luam nrog cov cim no.

Plywood tsuas yog tsim los ntawm cov nroj tsuag noj qab nyob zoo . Nyob rau tib lub sijhawm, txij lub Tsib Hlis txog Lub Cuaj Hli, cov khoom siv yuav tsum tau kho nrog cov tshuaj tshwj xeeb tiv thaiv kev ya raws. Cov khoom siv yuav tsum yog qib zoo.

Ua li cas?

Birch plywood muaj qib siab ntawm lub zog thiab ntau txheej txheej, cov ntawv txuas nrog ib leeg siv cov nplaum tshwj xeeb. Muaj qee hom plywood.

• FC - txhawm rau txuas cov veneer los xij rau ib leeg hauv cov ntawv no, siv cov tshuaj urea. Cov khoom no muaj cov dej noo tiv taus tsawg thiab pom zoo rau siv sab hauv tsev.
• FKM - hom no yog tsim los siv ib puag ncig tus phooj ywg zoo melamine, tau nce cov yam ntxwv tiv thaiv dej. Vim nws qhov zoo nyob hauv ib puag ncig, cov khoom siv no tau siv hauv kev tsim cov rooj tog thiab kho kom zoo nkauj sab hauv ntawm thaj chaw.
• FSF - yog cov khoom tiv taus ya raws. Gluing ntawm veneer nplooj ntawv hauv qhov kev coj ua no yog ua los ntawm kev siv cov tshuaj phenolic. Cov khoom lag luam zoo li no siv rau kev ua haujlwm sab nraum zoov.
• Laminated - hauv kev sib xyaw ntawm hom no muaj ib daim ntawv ntawm FSF, npog ob sab nrog cov khoom siv tshwj xeeb zaj duab xis. Cov plywood no tuaj yeem siv dua. Nws feem ntau yog siv hauv kev tsim cov ntawv ua haujlwm.
• Bakelized - lub hauv paus gluing ntawm cov ntawv ntoo hauv qhov sib txawv no yog bakelite cob. Cov khoom lag luam zoo li no tau siv rau hauv cov xwm txheej hnyav thiab thaum ua haujlwm monolithic.

Nyob ntawm seb hom kev ua haujlwm saum npoo av, cov ntawv plywood tuaj yeem yog peb hom: tsis txhuam, xuab zeb ntawm ib lossis ob sab.

Birch plywood los txog hauv ntau qhov qauv loj uas yog qhov xav tau ntau tshaj:

• 1525x1525 hli;
• 2440x1220 hli;
• 2500x1250 hli;
• 1500x3000 hli;
• 3050x1525 hli.

Nyob ntawm qhov loj me, plywood muaj qhov sib txawv tuab, uas yog los ntawm 3 hli txog 40 hli.

Cov cheeb tsam ntawm kev siv

Vim nws lub zog siab, cov ntoo plywood tau siv dav hauv ntau lub lag luam.

Tsev

Txawm hais tias suav nrog tus nqi siab, cov khoom siv nrov thaum ua tiav kev tsim kho thiab ua tiav cov haujlwm xws li:

• kev tsim kho vaj tse monolithic;
• kev teeb tsa plywood ua ib txheej hauv qab laminate thaum npaj hauv pem teb;
• kho kom zoo nkauj phab ntsa hauv kev tsim kho tus kheej.

Mechanical engineering

Vim nws lub teeb thiab lub zog, cov ntoo plywood tau siv hauv cov haujlwm hauv qab no:

• tsim cov phab ntsa thiab cov plag tsev hauv cov neeg nrog caij thiab tsheb thauj khoom;
• tiav ntawm lub cev ntawm kev thauj khoom thauj;
• siv daim ntawv FSF-ya raws cov dej noo hauv cov chav nrog cov av noo siab.

Kev tsim dav hlau

Aviation plywood yog siv los ntawm cov kws tsim txuj ci tsim qauv dav hlau.

Qhov kev xaiv tsim nyog tshaj plaws hauv qhov no yog cov khoom siv ntoo, vim nws tau ua los ntawm cov veneer zoo los ntawm gluing cov ntawv ib leeg siv cov kua nplaum phenolic.

Rooj tog kev lag luam

Birch plywood tau siv dav hauv kev lag luam no. Coj mus rau hauv tus account yam khoom, rooj tog rau chav ua noj, rau chav dej, vaj thiab khoom siv hauv tsev lub caij ntuj sov, ntau lub txee, rooj thiab ntau ntxiv yog tsim los ntawm nws.

Thaum tau paub ntau yam nrog cov yam ntxwv tseem ceeb ntawm birch plywood, nws yuav yooj yim dua rau cov neeg siv khoom los xaiv nws.
