Plywood: qhov luaj li cas (GOST). Standard ntau thiab tsawg pab ntawm plywood

Thawj plywood pib ua rov qab nyob rau hauv nruab nrab-xyoo pua puv 19. Thaum lub caij, qhov no yog ib tug heev cov ntaub ntawv uas siv rau sab hauv kho kom zoo nkauj, kev siv ntawm cov yam ntxwv ntsiab ntawm cov vaj tse, nyob rau hauv rooj tog, ntim, qho khoom ua si manufacturing, thiab hais txog. D. Niaj hnub nimno kev lag luam ua sib txawv heev plywood. Lub qhov ntev ntawm cov ntawv txheeb thiab lawv thickness txiav txim qhov zoo tshaj uas ntawm no cov ntaub ntawv thiab nws cov nqi.

Yuav ua li cas yog no cov ntaub ntawv uas

Plywood muaj ob peb khaubncaws sab nraud povtseg ntawm veneer glued nyob rau hauv xws li ib tug yam uas lub fibers nyob rau hauv uas nyob ib sab khaubncaws sab nraud povtseg yog perpendicular. Yog li ntawd, nws yog deprived ntawm lub ntsiab drawbacks ntawm ntoo - lub peev xwm los keej, ntsws thiab warp. Course vim thaum izgotovlenii fanery chemicals are used, particular, fenolnye or karbomidformaldeginye klei, Environmental bezopasnosti derevu she significantly ustupaet.

txheem qhov ntev

Thaum twg koj yuav cov khoom no yuav tsum tau them nyiaj mloog feem nyob rau hauv ntev thiab dav ntawm cov ntawv txheeb. Koj yuav nrhiav tau feem ntau plywood txheem ntau thiab tsawg pab nyob rau hauv khw muag khoom noj. Tej nplooj ntawv yog yooj yim rau nruab thiab thauj. Standard GOST plywood ntev - 2,44 m, dav -. 1.22 m thiab cov ntawv txheeb kuj ua ntau dua los yog tsawg dua. Haum ntau hom plywood yog 1,525 m nyob rau hauv dav (feem ntau square). los xij yuav ua tau mus 3,66 meters. Yog li plywood txheem ntau thiab tsawg pab - 2,44 x 1.22 m.

Yuav ua li cas tej zaum yuav thickness

Ntawm cov hoob kawm, qhov ntev thiab dav - yog tsis tsuas yog kev xaiv, uas tej zaum yuav sib txawv plywood. Ib qho tseem ceeb tshaj - yog nws thickness. Nyob rau hauv lub chaw ua khoom ntawm ntim thiab rooj tog zaum, piv txwv li, yog siv es nyias los xij. Nyob rau hauv xov lub chaw ua hauj lwm, raws li zoo raws li qhov kev siv ntawm cov vaj tse siv ntau thicker plywood. Loj nyob rau hauv no hwm yog nyob ntawm seb muaj pes tsawg tus khaubncaws sab nraud povtseg thiab lub thickness ntawm lub veneer.

Tso plywood koom raws li cov pa tuam txhab uas muag thiab Enterprises, thiab tshwj xeeb. Nyob rau hauv rooj plaub thawj cov ntaub ntawv uas yog ua ib tug tuab ntawm 3 mus rau 30 mm. Nyob rau hauv cov kauj ruam no ntawm qhov tseem ceeb uas hais txog 3 hli. Manufactured los ntawm tshwj xeeb tuam txhab uas muag xws li "aviation" plywood, lub thickness ntawm cov uas - thaum tswj lub zog - yuav ua tau heev me me.

Yuav ua li cas yog tsim nyog paub txog

Labeling yuav txiav txim nrog rau fiber kev taw qhia txojkev khaubncaws sab nraud povtseg. Feem ntau, lawv yog positioned raws, uas yog, qhov ntev ntawm daim ntawv. Tab sis tej zaum muaj embodiments nyob rau hauv uas lub fibers yog qhia raws li cov dav. Nyob rau hauv cov ntaub ntawv no, qhov loj ntawm lub veneer yog qhia prostanovkoy ntev nyob rau hauv lub thib ob qhov chaw. Nws zoo li no -. 1.22 x 2,44 m nyob rau hauv tus qauv los xij nrog li ib txwm coj ntawm fiber loj yog qhia raws li nram no: - 2,44 x 1.22 m.

Cov nab npawb ntawm cov khaubncaws sab nraud povtseg ntawm plywood

Qhov no tus nqi kuj sib txawv. Txawm li cas los, feem ntau lub los xij muaj ib tug khib naj npawb ntawm cov khaubncaws sab nraud povtseg (tsawg kawg yog peb). Tej zaum siv nyob rau hauv qhov siv thiab ua veneer los ntawm tib lub hom ntoo, tej zaum - ntawm txawv. Txojkev khaubncaws sab nraud povtseg no feem ntau yog ua los ntawm heev high-quality khoom. Nyob rau hauv nruab nrab ntawm no tej zaum yuav nyob rau hauv ib lub phaj zuj zus veneer. Tej zaum qhov muag tshwm sim thiab plywood nrog tsuas yog ib zoo txheej txheej. Nyob rau hauv cov ntaub ntawv no, qhov rov qab sab ntawm daim ntawv no yog hu ua thaub qab.

cov ntaub ntawv uas qib

Yog li ntawd koj rau tej lub hom phiaj xav tau plywood. Loj, thickness thiab tus xov tooj ntawm khaubncaws sab nraud povtseg - tsis tsuas tsis muab los xav thaum muas. Saib kuj yuav tsum raws cov tsiaj ntawv los yog hais txog zauv los raws li ib tug txojkev txheej. Thaum lub caij, raws li GOST 30427-96, muaj tsuas yog plaub hom plywood:

• A - Class. Nyob rau hauv cov ntaub ntawv no, nyob rau hauv pem hauv ntej saum npoo mus rau lub siab tev taus ntawm peb me me pob caus ntawd rau 1 m ^2. Nws yog ib heev du plywood yog siv mas rau kho kom zoo nkauj ntawm cov yam ntxwv ntsiab ntawm cov vaj tse.
• Nyob rau hauv - lub thib ob qib. Cov pob caus ntawd rau ib tug plywood yuav ua tau mus txog rau 10 ib 1 m ^2. Qhov no cov ntaub ntawv uas yog ib tug nqi me ntsis tsawg sab saum toj-nqis siab tshaj.
• C - ib tug peb lub qib. Qhov no plywood yog feem ntau yog siv rau qhov siv thiab ua ntim los yog thaum designs.
• D - plaub qib. Cov hom no kuj siv mas rau hauv lub ntim kev lag luam.

Qhov no npav yog tam sim no siv, tab sis nws yog suav tias yog obsolete. Yog li ntawd, lub ntau yam nyob rau ntawm daim ntawv lo yuav xaiv tsuas Latin numerals kuv mus IV. Cov tsab ntawv E nyob rau hauv lub tshiab labeling lom qhov zoo tshaj plaws cov neeg tseem ceeb cov ntaub ntawv uas.

Loj 10 hli plywood

Qhov no yog cov feem ntau nrov hauv daim ntawv ntawm cov khoom. Siv no plywood mas nyob rau hauv lub tsev thiab kev tsim thiab rau qhov siv thiab tsev hnab ntawv, xws li nws ua li.

10 hli plywood loj tej zaum yuav txawv. Txawm li cas los, raws li nrog lwm yam thickness, feem ntau muag thiab siv txheej txheem los xij 2,44 x 1.22 m.

Ntau ntawm cov dej kuj

Nyob rau hauv tas li ntawd, muaj ntau hom ntawm cov khoom no. Nyob rau hauv cov ntaub ntawv no, lub plywood yog muab rau tus account lub peev xwm kom lawv cov kev ua tau zoo ntawm cov zaubmov ntawm av noo. Qhov zoo tshaj ntawm cov khoom nyob rau hauv cov cheeb tsam no mas nyob ntawm seb tus lo raug xaiv rau tsevneeg veneers.

Labeling rau dej kuj:

• FC - cov khoom siv rau sab hauv daim ntaub ntawv nyob rau hauv qhuav tej thaj chaw. Nws yog tsis heev dej-resistant plywood, tab sis environmentally huv. Nyob rau hauv cov ntaub ntawv no, lub khaubncaws sab nraud povtseg yog sib raug zoo adhesives raws li urea-formaldehyde resins.
• FSF - dej-resistant plywood, qhov ntev uas yuav tsum yog tus qauv los yog tsis. Qhov no embodiment muaj ib tug ntau dua hardness thiab txhua yam muaj zog tshaj FC. Siv feem ntau rau kev ua tau zoo sab nraud ua hauj lwm, piv txwv li, thaum lub hauv paus unit nyob rau hauv lub ru tsev. Cov khaubncaws sab nraud povtseg nyob rau hauv xws li ib tug cov ntaub ntawv uas yog tsau siv adhesives raws li formaldehyde resins.
• FOF - laminated plywood. Nyob rau hauv rooj plaub no tus txheej khaubncaws sab nraud povtseg ntxiv glued los xij ntawm tshwj xeeb zaj duab xis uas ua hauj lwm pab tsis tau tsuas yog zoo heev tiv thaiv los ntawm noo noo, tab sis kuj los ntawm UV kis raws li ntau yam hom corrosive xov xwm.

Variations nyob rau hauv lub degree ntawm kev

Nyob rau hauv tas li ntawd, plywood, luaj li cas thiab degree ntawm dej kuj uas yuav ua tau txawv, tsis tau raws nyob rau hauv zoo thiab ua lub ntsej muag khaubncaws sab nraud povtseg. Nyob rau hauv no hais txog, cov ntaub ntawv uas yog dej num raws li nram no:

• SH1 - npe yog av nrog tsuas yog ib - pem hauv ntej - sab;
