Tam sim no, hauv ntau thaj tsam ntawm kev tsim kho, ntau hom ntoo tau siv. Cov khoom siv no muaj cov tswv cuab tseem ceeb ntawm cov txiaj ntsig zoo thiab cov yam ntxwv. Nyias, peb tuaj yeem pom zoo ib yam li nkoj plywood. Xav txog cov yam ntxwv tseem ceeb ntawm cov khoom siv no thiab cov tseev kom muaj uas yuav tsum tau ua rau nws.
Nws yog dab tsi?
Nkoj plywood yog daim ntawv laminated veneer. Hauv qhov no, cov kev taw qhia ntawm cov fibers hloov pauv los ntawm ib txheej mus rau lwm qhov. Rau impregnation ntawm ib txheej ntawm cov khoom, tshwj xeeb bakelite muaj pes tsawg leeg siv, yog li ntawd, cov khoom lag luam feem ntau hu ua bakelized plywood.
Xws li cov ntawv ntoo muaj qib siab ntawm lub zog, lawv nyuaj heev
Cov khoom siv no feem ntau yog siv hauv kev lag luam dav hlau thiab hauv kev tsim cov nkoj me me. Tab sis qee zaum nws tseem tau yuav khoom rau kev ua haujlwm txheem.
Marine plywood muaj tus lej ntawm cov khoom tseem ceeb
- Hluav taws kub tsis kam . Cov khoom siv yuav tsis hlawv. Nws tuaj yeem tsuas yog hluav taws, thaum tso pa taws me me, uas tsis muaj cov tshuaj lom ntau. Qhov no tuaj yeem tshwm sim ntawm qhov kub tsawg kawg 350 degrees.
- Dej tsis kam . Bakelized nplooj ntawv tsis raug puas lossis deformed nyob rau hauv kev cuam tshuam ntawm cov dej noo ntau. Nyob rau tib lub sijhawm, kev pab lub neej yam tsawg kawg nkaus ntawm cov ntaub ntawv no, ua haujlwm nrog kev sib cuag nrog cov dej nruab nrab, tuaj yeem mus txog 15 xyoos.
- Lub zog . Lub zog qib ntawm hom ntoo no ua ke nrog lub zog yam ntxwv ntawm cov ntawv hlau.
Ib qho ntxiv, nws tuaj yeem sau tseg tias cov khoom siv no tiv taus cov pwm thiab kab mob. Kev ua tib zoo saib xyuas tshwj xeeb ntawm cov khoom thaum tsim khoom tsis pub lawv tshwm rau ntawm qhov chaw.
Cov khoom siv yog qhov ua tau zoo tiv thaiv kev cuam tshuam thiab cov khoom tseem ceeb . Ib qho ntxiv, nws yuav luag tsis raug rau cov teeb meem huab cua phem, yog li nws tuaj yeem siv los kho cov rooj tog zaum uas yuav muab tso rau sab nraum zoov. Feem ntau, chav ua noj hauv vaj thiab gazebos tau tsim los ntawm tsob ntoo zoo li no.
Cov qauv nkoj kuj tseem tuaj yeem siv los teeb tsa sab hauv tsev, phab ntsa thiab npog qab nthab. Tab sis qhov no nws tau pom zoo kom muab qhov nyiam rau cov ntawv laminated nyias. Txog kev tsim khoom ntawm lub lawj ib feem rau lub nkoj, nkoj plywood ntawm qib tshwj xeeb FBS raug coj los.
Lub thickness ntawm cov ntoo no tuaj yeem sib txawv ntawm 4 txog 40 hli . Qhov ntev ntawm cov khoom tuaj yeem ncav cuag 1500, 4400, 4900 mm (tab sis kuj tseem muaj cov ntawv txuas ntxiv - 5600, 5700 thiab 7700 mm). Qhov dav ntawm ib daim ntawv plywood tuaj yeem yog 1250, 1500, 1550 hli.
Yuav tsum muaj
Hauv kev tsim cov ntoo plywood, qee qhov xav tau tseem ceeb rau qhov zoo ntawm cov khoom siv yuav tsum raug coj mus rau hauv tus account. Lawv tuaj yeem nrhiav pom hauv Askiv Tus Qauv 1088/66. Thiab tag nrho lawv tau teev tseg hauv daim ntawv pov thawj GOST 11539-83 ntawm 1985.
Tus txheej txheem muab rau ob peb qib sib txawv ntawm plywood marine
- FBV . Hom ntawv no yog ib daim ntawv, rau qhov ua kom tsis huv thiab lo uas tshwj xeeb cov dej-soluble sib xyaw tau siv. Feem ntau nws yog phenol-formaldehyde cob. Tab sis tib lub sijhawm, nws tsuas yog siv rau sab nrauv ntawm cov khoom.
- FWB 1 . Hom no zoo ib yam li yav dhau los. Txawm li cas los xij, ntawm no phenol-formaldehyde cob tau siv rau ob sab sab nrauv thiab sab hauv.
- FBS . Qib no ntawm cov ntoo plywood yog glued nrog cawv-soluble phenol-formaldehyde cob. Tsuas yog cov txheej sab nrauv raug kho nrog qhov tsis hnov tsw no.
- FBS1 . Ib hom tshuaj ntawm hom no raug kho nrog cov tshuaj muaj cawv-soluble ntawm ob sab.
Nkoj plywood tuaj yeem faib ua 2 pawg loj - cov khoom qub thiab tsis yog hom qub . Cov hom no muaj qhov xav tau sib txawv. Yog li, thawj daim ntawv yog tsim los ntawm tshwj xeeb Okume veneer. Cov khoom lag luam yog qhov txawv los ntawm lawv qhov hnyav tsis ntau, qib siab ntawm kev yoog raws thiab ua haujlwm ntev.
Cov classic version muaj laminated nto kho nrog cov dej tsis sib txuas . Nws feem ntau siv ua ke nrog epoxy thiab fiberglass. Cov plywood no sib piv hauv lub zog rau cov khoom lag luam carbon. Nws yog qhov txawv los ntawm cov khoom tshwj xeeb zoo nkauj, uas txiav txim siab nws tus nqi siab.
Feem ntau nws tau siv hauv kev tsim kho lub lawj rau cov yachts, cov nkoj zoo tib yam.
Cov plywood uas tsis yog-classical yog tsim los ntawm ntau yam tawv ntoo, suav nrog beech, birch, thiab poplar. Cedar thiab ntoo thuv qee zaum siv. Cov plywood no tuaj yeem yog hom ua ke. Hauv qhov no, txheej txheej saum toj kawg nkaus ntawm cov khoom yog ua los ntawm cov tawv ntoo tshwj xeeb, thiab sab hauv yog twb tau ua los ntawm cov tawv ntoo.
Qhov ntau yam no yuav tsum tsis txhob siv rau cov haujlwm ua haujlwm - nws feem ntau yog siv rau kev kho kom zoo nkauj sab hauv lossis tsim rooj tog
Tus nqi ntawm cov ntaub ntawv no yuav qis dua me ntsis piv rau qhov kev xaiv yav dhau los.
Ntxiv rau qhov xav tau saum toj no, muaj lwm qhov tseem ceeb uas yuav tsum tau coj mus rau hauv tus account thaum tsim khoom thiab teeb tsa cov khoom . Cov txheej sab nraud ntawm cov ntawv tuaj yeem tsuas yog ua los ntawm cov tawv tawv tawv veneer. Hauv cov qauv sab hauv, kev sib txuas ntawm cov ntsiab lus sib txawv nrog txhua lwm yam tau tso cai. Hauv qhov no, qhov dav ntawm txhua kab yuav tsum yog yam tsawg 400 mm rau FBS hom lossis 200 mm rau txhua lwm yam.
Hauv qhov no, cov kab sib txuas ntawm qhov sib txuas sab hauv yuav tsum tsis txhob coincide. Tsuas yog qhov xwm txheej no cov khoom yuav muaj zog thiab khov kho tau. Sab nrauv ntawm plywood yuav tsum tsis muaj thaj chaw uas tsis tau npog nrog cov kua roj vanish thiab lwm yam tshwj xeeb sib xyaw.
Txawm tias cov npuas me me thiab thaj chaw tsis muaj kev nyuaj siab yuav tsum tsis txhob nyob ntawm daim ntawv . Kev sib tshooj lossis qhov tsis sib xws uas muaj qhov siab ntau dua 1 millimeter kuj raug txwv. Txhua daim ntawv tsuas tuaj yeem txiav ntawm cov ces kaum raug. Hauv qhov no, qhov sib txawv ntawm ib lub 'meter' linear yuav tsum tsis pub ntau tshaj 2 millimeters.
Qhov kawg ntawm txhua daim ntawv yuav tsum ua tib zoo ua
Ntawm cov qauv ntawm FBS hom, qhov kawg tau ua tiav nrog txheej ntxiv ntawm bakelite muaj pes tsawg leeg. Ntawm qhov piv txwv ntawm FBV hom, lawv tau npog nrog cov tshuaj tiv thaiv tshwj xeeb.
Cov ntaub ntawv (kho kom raug)
Feem ntau ntawm cov ntawv no yog ua los ntawm veneer. Nws tuaj yeem yog ntau yam sib txawv . Cov qauv kim tshaj plaws thiab zoo tshaj plaws tau txiav txim siab ua veneer ua los ntawm cov ntoo ntoo txawv (ua ntej tshaj plaws, okume lossis keruing).
Cov ntaub ntawv tsim los ntawm lub hauv paus yog qhov txawv los ntawm qib tshwj xeeb ntawm kev ua haujlwm ntev thiab ntseeg tau . Tab sis cov qauv no tau tsim tshwj xeeb rau txawv teb chaws, yog li nws muaj teeb meem ntau dua los yuav lawv. Rau ib square meter ntawm cov plywood nrog tuab txog 3 hli, koj yuav tau them txog 1200-1300 rubles.
Plywood ua los ntawm birch veneer ua raws li kev sib piv hauv tsev .… Cov ntaub ntawv zoo li pheej yig, lawv cov nqi yog kwv yees li 2 zaug tsawg dua tus nqi ntawm qhov kev xaiv yav dhau los. Tab sis qib ntawm lub zog thiab ua haujlwm ntev yuav qis dua.
Tsim
Raws li txoj cai, cov qauv ntawm cov plywood muaj cov yam ntxwv zoo nkauj. Lawv tuaj yeem tsim ua xim sib txawv, suav txij lub teeb beige mus rau chocolate thiab liab . Qee cov qauv raug tsim ua xim dub.
Marine plywood yog coated nrog cov kua roj vanish tshwj xeeb . Cov qauv zoo li no muaj qhov ntxhib me ntsis. Cov khoom lag luam laminated muaj qhov ua kom du tag nrho. Cov ntawv corrugated kuj tau tsim hnub no. Lawv tau siv rau kev tso cov plag tsev, vim tias lawv suav tias yog kev nyab xeeb tshaj plaws rau tib neeg - nws yuav luag tsis yooj yim sua rau lawv.
Qee lub sij hawm sab hauv ntawm thaj chaw tau ua tiav nrog plywood-resistant plywood ua los ntawm ntau hom veneer. Cov kev sib xyaw ua ke no tso cai rau koj los tsim qhov zoo nkauj thiab tsim qauv qub. Thiab lawv kuj tuaj yeem siv rau kev kho kom zoo nkauj sab nrauv ntawm cov rooj tog.
