Thaum yuav ib lub tsev lossis cov khoom tiav, koj yuav tsum paub txog nws qhov ua tau zoo thiab tsis muaj zog, ua haujlwm tau zoo thiab yam ntxwv zoo. Txhua lwm qhov zoo yuav nyob ntawm qhov tuab thiab qhov hnyav ntawm plywood. Cov ntaub ntawv ua tiav ntau ntxiv tuaj yeem tau txais los ntawm kev nyeem txog cov chaw tsim khoom, cov khoom siv raw rau kev tsim khoom, kev ntsuas ntawm ib hom tshwj xeeb.

Yam cuam tshuam

Plywood yog cov khoom siv ntau txheej ntawm veneer nplooj ntawv txuas nrog hauv cov lus qhia ntawm cov ntoo hla. Veneer yog txheej txheej ntoo, tsis ntau tshaj 4 hli. Hauv kev tsim cov plywood, veneer los ntawm ntau hom ntoo tau siv, qhov sib txawv tsuas yog hauv cov txheej txheem tsim khoom. Nws qhov hnyav thiab cov yam ntxwv yuav txawv, nws txhua yam nyob ntawm qhov tshwj xeeb nqus, kev ntxhib los mos, dej noo thiab tiv taus dej. Yam uas cuam tshuam rau qhov hnyav tshaj yog qhov tuab thiab thaj tsam ntawm cov khoom, nrog rau hom ntoo.

Rau gluing veneers ua ke, formaldehyde cob tau siv. Nyob rau hauv lem, nyob ntawm seb cov additives, plywood tau muab faib ua ob peb hom.

• FBA yog cov khoom lag luam ib puag ncig zoo, nws muaj cov kua nplaum ntuj. Tsawg noo noo tsis kam.
• FB - bakelite. Tsis ntshai ya raws, siv hauv kev tsim nkoj. Txhua txheej yog glued ua ke nrog phenolic resins thiab impregnated nrog cov kua roj vanish bakelite.
• FC - qhov muaj pes tsawg leeg suav nrog urea. Nws muaj cov dej tsis kam tiv taus, nws tsuas yog siv rau kev kho kom zoo nkauj sab hauv.
• FSF - nrog ntxiv ntawm phenol. Cov khoom ruaj khov nrog kev tiv thaiv ya raws ntau ntxiv. Nws tuaj yeem siv rau kev kho kom zoo nkauj sab hauv thiab sab nrauv.
• FOF - laminated yam khoom. Cov yam ntxwv zoo ib yam li rau FSF, qhov sib txawv yog tias nws muaj ob sab ua los ntawm zaj duab xis tshwj xeeb.
• BS lossis aviation - cov khoom siv zoo tshaj plaws, veneer rau kev tsim khoom tsuas yog siv cov qib zoo tshaj plaws. Txaus txaus ntim, kua cawv-soluble kua nplaum yog siv rau kev tsim khoom.
• BV tsis tiv taus ya raws li BS. Cov veneer yog ua ke nrog cov dej-soluble sib xyaw.

Nws yuav tsum nco ntsoov tias qhov ntom ntom yuav tsis nyob ntawm hom kua nplaum. Tab sis nws tuaj yeem hloov pauv los ntawm tus nqi ntawm cov resins. 1 m3 ntawm cov tshuaj muaj qhov hnyav txog 800 - 850 kg. Yog li ntawd, siv cov nplaum ntau dua, qhov siab dua ntawm cov plywood tiav. Cov neeg tsim khoom rau lub hom phiaj ntawm kev tsis muaj kev puas tsuaj thiab kev phooj ywg ib puag ncig tuaj yeem txo cov kua nplaum.

Txhua tus yam ntxwv ntawm plywood muaj feem cuam tshuam rau ib leeg, thiab ntau nyob ntawm qhov tuab . Piv txwv li, koj tuaj yeem txiav txim siab FC plywood 10 hli tuab - qhov no yog hom nrov tshaj plaws thiab xav tau. Cov khoom lag luam ntawm cov tuab no muaj 7 txheej txheej ntawm cov veneer, ib pob ntawm 1 lub voos xwmfab yuav suav nrog 43 nplooj ntawv, tab sis los ntawm cov qauv ntawm cov ntawv hauv ib pob nws yuav yog 3 daim tsawg dua. Yog li, nws yuav tsis yog 1, tab sis 0.93.

Nws yog qhov yuav tsum tau coj mus rau hauv tus account qhov yuam kev tso cai hauv tuab, nws nyob ntawm seb cov khoom raug xuab zeb lossis tsis.

Cov ntawv ntawm 2-8 hli yog siv hauv kev tsim cov rooj tog, 8-12 hli-raws li qhov ua tiav . Plywood tuaj yeem tsim khoom raws li qhov ntau thiab tsawg sib xws rau GOST - 1.525 square metres, 1.22x2.44, 1.25x2.5, 1.5x3, 1.525x3.05 meters. Thiab kuj ntawm kev thov - lwm yam tsis xav tau los ntawm cov neeg siv khoom.

Pawg plywood los ntawm cov khoom sib txawv

Txhawm rau txiav txim siab qhov hnyav ntau dua ntawm plywood, muaj cov rooj tshwj xeeb, txhua qhov tsim nyog tsis suav thiab suav tau twb tau nkag rau hauv lawm. Nov yog qhov ntom ntom ntawm veneer ua los ntawm cov ntaub ntawv no.

• Birch ntoo - 650 kg / m3.
• Larch, ntoo thuv lossis spruce - 550 kg / m3.
• Poplars - 500 kg / m3.
• Cottonwood lossis seiba - 350 kg / m3.
• Bakelite plywood tuaj yeem sib txawv sib txawv, nws qhov ntom yog 1200 kg / m3.

Birch plywood muaj qhov siab tshaj plaws, yog li nws lub zog muaj txiaj ntsig yog qhov zoo tshaj plaws.

Cov khoom zoo li no tau nce kev tiv thaiv kev ntxhov siab thiab noo noo. Cov xim yuav tsum yog daj-dawb, qee zaum liab dawb, nrog kev pom zoo . Txawm hais tias ob nplooj ntawv ntawm plywood muaj thaj tsam ib yam thiab tuab, tab sis tau ua los ntawm ntau hom ntoo, siv cov kua nplaum sib txawv, kev nias thiab tshuab ziab khaub ncaws sib txawv - qhov hnyav yuav tsis zoo ib yam.

Koj tuaj yeem suav qhov hnyav ntawm cov khoom koj tus kheej, paub cov mis - "ntom x ntim = loj ". Piv txwv li, koj yuav tsum paub ntau npaum li cas 105 nplooj ntawv ntawm coniferous plywood hnyav, 1500x3000 mm hauv qhov loj thiab 8 mm tuab. Peb yuav tsum tsis txhob hnov qab txhais txhua qhov ntsuas rau hauv ib chav ntsuas, qhov no yog ntsuas. Tam sim no koj yuav tsum hloov cov ntaub ntawv rau hauv cov mis:

1.5x3x0.008x550x105 = 2079 kg.

Cov ntawv tuab thiab tuab tuab hnyav npaum li cas?

Thickness ntawm cov ntawv nyias nyias txawv ntawm 0.4 txog 6.5 mm. Qhov no suav nrog plywood aviation thiab hom FC, FSF. Piav txog qhov nruab nrab ntom rau plywood los ntawm ntau hom ntoo, cov hauv qab no tuaj yeem ua qhov txawv.

• Cov ntawv nrog qhov ntev 2.44x1.2 meters, 6.5 mm tuab los ntawm birch - 12.6 kg, thiab los ntawm conifers - 10.6 kilograms.
• Plywood nrog qhov ntev tib yam tab sis 12 mm tuab los ntawm birch veneer - 23.2 kg, los ntawm coniferous - 19.6 kilograms.

Qhov sib txawv ntawm qhov hnyav yuav yog rau cov khoom siv nrog cov duab plaub, nrog tuab ntawm 6.5 hli

• Birch - 9.07 kg.
• Coniferous - 10 kg.

Plywood ntawm cov tuab tuab suav nrog cov ntawv - 8, 9, 10, 12 thiab 15 mm. Cov ntaub ntawv zoo li no tau siv hauv kev tsim kho, rooj tog tsim khoom, tshuab kho tshuab, thiab vov tsev. Los ntawm hom nto, nws tuaj yeem faib ua polished thiab tsis ua haujlwm. Cov qib siab tshaj plaws yuav tsum yog nrog kev zoo nkauj, zoo nkauj zoo nkauj thiab pom.

Plywood ntawm cov tuab no feem ntau yog tsim los ntawm FK thiab FSF qib.

Ua piv txwv, xav txog cov veneer nrog tuab ntawm 12 hli, nrog qhov ntsuas 1.22x2.44 meters

• Birch - 23.2 kg.
• Koob - 20.6 kg.

Cov plywood tuab suav nrog cov ntawv uas tsis suav nrog - 18, 20, 21, 24, 30 mm. Nws lub ntsiab tseem ceeb yog lub zog, yog li cov khoom siv feem ntau siv los ua lub luag haujlwm hauv kev tsim cov rooj tog, kev tsim kho, thiab lwm yam Sib cais, ib leeg tuaj yeem tawm cov khoom siv nrog tuab ntau dua 40 hli, nws yog tsim los rau xaj, vim nws muaj qhov tshwj xeeb nqaim heev.

Cov veneer nrog cov tuab tuab tau tsim hauv peb hom - FC, FSF, FOF. Qhov nrov tshaj plaws yog 18 thiab 21 hli. Piv txwv li: birch veneer 1.525x1.525 meters nrog tuab 18 yuav hnyav 35.8 kg.

Plywood hnyav npaum li cas, koj yuav tsum paub kom xa mus rau qhov chaw ua haujlwm . Muaj ntau lub rooj npaj ua nrog ob qho tib si softwood thiab birch veneer tes taw hnyav li. Koj tseem tuaj yeem siv lub laij lej online, tsuas yog nkag mus rau txhua qhov ntsuas thiab nyem lub pob "xam".
