Thaum lub sijhawm tsim kho thiab ua haujlwm, ntau yam ntaub ntawv tau siv feem ntau, ntawm cov plywood uas nyiam tshaj plaws. Nws tseem nyob hauv kev thov rau ntau xyoo lawm, txawm tias qhov tseeb tias cov ntaub ntawv tshiab tshwm ntawm lub khw niaj hnub no.
Hauv kab lus no, peb yuav qhia koj kom ntxaws txog cov plywood nyias, nws cov yam ntxwv, hom, qhov ntau thiab tsawg, ntawm qhov chaw thov.
Peculiarities
Cov ntawv plywood nyias tau siv rau hauv txheej txheem ntawm txheej txheej ntawm lub tsev lossis txhim kho hauv av. Nws yog qhov tsis tuaj yeem hloov pauv hauv kev ua qauv dav hlau, ua tiav cov txheej txheem.
Zoo li lwm yam khoom siv hauv tsev, plywood tau tsim raws li tsoomfwv cov cai thiab cov qauv. Nws cov yam ntxwv tshwj xeeb, kev ua haujlwm thiab ntsuas cov cai tau teev tseg hauv GOST 30427, GOST 7016, GOST 9462, GOST 3916.1 - 96.
Cov ntaub ntawv no hais meej meej tias tsuas yog veneer - cov khoom ntoo - yuav tsum siv rau kev tsim khoom.
Cov plywood nyias ua los ntawm cov veneer zoo yog tus yam ntxwv los ntawm:
- lub zog;
- hnav tsis kam thiab tiv taus corrosion;
- siab coefficient ntawm flexural zog nyob rau hauv cov lus qhia sib txawv;
- kev pab lub neej ntev;
- qhov tsis muaj cov tshuaj phem, piv txwv li, hauv qhov ua kom tsis huv uas txhua txheej txheej ntawm cov veneer raug kho;
- zoo nkauj tsos;
- qib siab ntawm thermal conductivity;
- kev phooj ywg zoo;
- tiv taus kub heev;
- ya raws tsis kam
Qhov no yog cov khoom lag luam muaj ntau yam, lub cev thiab cov txheej txheem kev ua haujlwm uas siab heev.
Ib qho ntxiv, tsis txhob hnov qab tias nws nyob hauv kev sib haum xeeb nrog yuav luag txhua cov ntaub ntawv, tsis yog ua tiav cov ntaub ntawv.
Saib
Raws li tsoomfwv txoj cai lij choj saum toj no, muaj ntau hom thiab kev faib tawm ntawm cov plywood nyias.
Los ntawm qib . Nyob rau hauv tag nrho, hnub no muaj 5 ntau yam. Tau kawg, nws siab dua, qhov zoo dua ntawm cov khoom, thiab nws tus nqi siab dua. Qib tsib yog suav tias yog cov neeg tseem ceeb, nws yog rau qeb E.
Los ntawm veneer kev ntxhib los mos . Cov txheej txheem no qhia txog hom ntoo uas cov veneer tau ua - cov khoom tseem ceeb rau kev tsim cov plywood. Cov khoom lag luam zoo tshaj plaws yog ua los ntawm ntoo coniferous lossis birch veneer.
Los ntawm txheej txheem kho saum npoo av
Muaj ntau txoj hauv kev los xuab zeb plywood nto, uas tau siv hauv cov txheej txheem tsim khoom:
- cov khoom tuaj yeem xuab zeb ntawm ib sab thiab xaiv Ш1;
- kev sib tsoo tau ua tiav ntawm ob sab - Ш2;
- tsis muaj kev sib tsoo - NSh;
- nto ntawm cov khoom yog polished thiab laminated - FOF.
Los ntawm tus naj npawb ntawm txheej . Cov plywood nyias tuaj yeem yog peb txheej, plaub txheej lossis ntau txheej.
Tau kawg, txhua qhov ntsuas tsis tseem ceeb thaum xaiv cov khoom. Tab sis raws li tus naj npawb ntawm cov txheej, qhov ntsuas no tsuas yog tus lej geometric, uas tsis muaj kev cuam tshuam rau cov neeg kho tshuab lub zog thiab ya raws tsis kam ntawm cov khoom.
Qhov ntev (kho kom raug)
Ntoo plywood ntawm kev tsim kho kev lag luam tau muab faib ua ob pawg.
Kev tsim kho . Pawg no suav nrog hom FK thiab FSK. Cov tuab ntawm cov khoom yog los ntawm 3 txog 40 hli, tab sis cov no yog cov nyiam tshaj plaws.
- 4 hli - muaj ob hom: txhuam thiab tsis txhuam. Ua los ntawm ntau hom ntoo. Cov khoom siv no feem ntau yog siv rau sab nrauv kho kom zoo nkauj thiab tsim cov rooj tog zaum.
- 3 hli - tus yam ntxwv los ntawm qhov siab coefficient ntawm kev yoog raws, muaj zog txaus thiab ywj. Nws yog siv rau kev tsim cov khoom plig, ntxiv rau hauv kev tsim cov ntawv ci nyuaj rau hauv pem teb thiab phab ntsa npog.
Aviation . Cov khoom siv no yog BP-A, BP-V, BS-1, BPS-1V. Lub thickness ntawm daim ntawv tuaj yeem ua qhov tsawg tshaj plaws - los ntawm 0.4 txog 0.6 hli. Cov plywood no tau siv dav hauv ntau yam lag luam. Nws yog tus yam ntxwv los ntawm kev yoog raws, du thiab ruaj khov. Nws yog qhov yooj yim heev los ua haujlwm nrog cov khoom siv no, thiab lub cev thiab kev ntsuas tsis pub nws siv rau hauv cov cheeb tsam xws li dav hlau thiab tshuab siv tshuab, tsim khoom, tsim khoom siv suab paj nruag, thiab lwm yam.
Niaj hnub no, ntau lub tuam txhab tsim kho tau koom nrog tsim cov ntawv plywood nyias, yog li yog tias koj xav tau cov khoom lag luam txog li 1 hli tuab, koj tuaj yeem ua tus kheej xaj.
Cov ntawv thov
Niaj hnub no, txhua yam uas tuaj yeem ua tau yog tsim los ntawm cov plywood nyias. Nws tau siv dav hauv ntau yam haujlwm ntawm kev ua haujlwm, ob qho tib si hauv kev tsim khoom thiab hauv lub neej txhua hnub.
- Nyob rau hauv tus txheej txheem ntawm ua khoom plig.
- Hauv thaj tsam ntawm kev ntsuas.
- Rau kev rov kho dua ntawm parquet.
- Rau kev ua qauv. Ntau zaus, kos duab, txo cov ntawv luam ntawm ntau lub tsev thiab cov qauv tsim los ntawm cov khoom siv no. Qhov no txhais tau tias cov khoom siv tsis tuaj yeem hloov pauv hauv kev tsim vaj tsev thiab tsim qauv.
- Rau kev tsim cov twj paj nruas.
- Hauv kev lag luam rooj tog - rau rooj tog hauv ncoo, cov tog zaum, rooj zaum thiab lwm yam.
- Ntau tus neeg tsim qauv siv cov plywood nyias los coj lawv cov tswv yim muaj tswv yim rau lub neej. Nws yog cov khoom siv rau sab hauv thiab sab nrauv kho kom zoo nkauj.
- Rau ntim cov khoom tawg yooj yim thaum thauj mus los.
Txawm hais tias cov ntawv plywood nyias tsis tau tsim los tiv cov khoom hnyav, lawv daim ntawv thov yog dav heev thiab sib txawv.
