Carpentry panels: kev tsim kho, qhov ntev thiab zoo

Hnub no, Savo Kusić tau tsom mus rau qhov rais ntoo, wood-aluminium Qhov rais, kev cai Qhov rais, qhov rooj thiab thov lus hais. Cov ntawv no tseem yog ib qho kev archive thiab tsis yog ib qho kev muag khoom tam sim no ntawm cov ntoo ntoo.

Lub hom phiaj thiab kev faib tawm

Cov ntoo ntoo yog siv los ua qhov rooj, phab ntsa cladding, built-in cov rooj tog zaum, thiab lwm yam.

Ntoo boards muab faib ua veneered tsuas yog nyob rau ntawm ib los yog ob sab thiab uncoated; sanded ntawm ob sab thiab unsanded; rau daim hlau ntawm qhov zoo tib yam thiab nce qhov tseeb; Nyob rau ntawm cov laug cam glued nrog cov khoom siv dag zog thiab ntawm cov nplaum nplaum nrog casein glues. Qhov ntev ntawm cov phaj no tau muab rau hauv lub rooj 8.

Raws li qhov zoo ntawm cov ntoo ntawm nplooj, uncoated boards yog ua nyob rau hauv peb hom: A, AB thiab B (tab. 9).

Ordinary carpentry boards yog tsim nyob rau hauv chav kawm I thiab II. Chav kawm I panels raug them nrog txiav veneer ntawm chav kawm I thiab II.

Kev xaiv ntawm hom veneer rau cov ntoo ntoo yog ua raws li cov ntaub ntawv los ntawm lub rooj. 10.

Lub thickness ntawm tag nrho cov khaubncaws sab nraud povtseg ntawm txhua daim ntawv ntawm qhov muag tsis pom veneer ntawm uncoated boards yuav tsum yog rau boards thickness.16rau 35 mm - 3,6 mm, rau daim hlau dhau35 mm- 4,0 mm. Rau coated panels, lub thickness ntawm cov veneer txiav yog txiav txim siab raws li tus qauv siv. Nyob rau hauv panels npaj rau ua wagons, lub thickness ntawm txiav veneer yuav tsum yog 1,5 mm.

Kev tsim cov core thiab veneers

Carpentry boards yog tsim los ntawm softwood, softwood thiab birch ntoo. Hauv txhua lub vaj huam sib luag, slats yuav tsum yog tib hom ntoo. Cov slats nyob rau hauv lub slab yuav ua tau glued los yog unglued. Kev txuas ntxiv ntawm cov slats hauv cov phiaj xwm raws li qhov ntev yuav tsum tau ua ua ke nrog qhov kev ncua deb ntawm qhov txuas ntxiv ntawm cov slats uas nyob ib sab yam tsawg kawg nkaus.150 mm. Rau kev txhawb nqa cov qauv, kev txuas ntxiv ntawm cov slats raws qhov ntev yog tsis tso cai.

Kev kos duab ntawm cov ntoo ntoo nrog slatted core thiab veneer

** Duab8: Cov qauv ntawm cov ntoo ntoo; H - thickness; L - ntev: B - dav **

Cov nplooj ntawv ntawm cov laug cam uas tsis muaj coated yuav tsum yog ua los ntawm birch, alder, beech los yog ntoo thuv veneer uas nws qhov zoo tsis yog hauv qab hom BB raws li tus qauv tam sim no rau plywood, thiab cov nplooj ntawv coated boards - ntawm txiav veneer uas nws zoo tsis yog hauv chav kawm II (daim duab.8).

Kev tsim kho ntawm cov ntoo ntoo yuav tsum sib luag, piv txwv li hauv ob sab phlu ntawm cov vaj huam sib luag yuav tsum yog tuab tuab. Carpentry boards uas yog coated rau ntawm ib sab nrog txiav veneer yuav tsum muaj nyob rau sab nraud ib tug ntxiv txheej ntawm peeled veneer, lub thickness ntawm uas yog sib npaug zos rau cov thickness ntawm txiav veneer ntawm lub ntsej muag ntawm lub rooj tsavxwm. Kev taw qhia ntawm cov ntoo fibers ntawm cov ntawv los ntawm sab xub ntiag thiab sab nraub qaum ntawm cov cladding panels yuav tsum zoo ib yam, thiab raws li qhov ntev ntawm cov slats - thaum uas tig mus los yog qhia. Nyob rau hauv uncoated thiab coated boards, nws raug tso cai tias cov ntaub ntawv txheej yog sib sau ua ke, glued los ntawm veneer strips tsawg kawg yog 100 mm dav, nrog rau cov mob uas veneer raug xaiv raws li qhov zoo ntawm cov ntoo thiab nws cov xim, thiab rau coated boards - raws li nws kev ntxhib los mos.
Nyob rau hauv cov nplooj ntawv ntawm sab nraum qab ntawm coated panels nrog longitudinal kev taw qhia ntawm cov ntoo fibers, nws raug tso cai mus txuas ntxiv veneer raws li ntev ntawm cov fibers.
Nyob rau hauv cov ntawv sab nrauv ntawm cov ntoo ntoo uas tsis muaj coated thiab coated, qhov sib txawv ntawm ob lub pob qij txha txog li 0,3 mm dav tau tso cai, nyob rau hauv ntev tsis pub tshaj 250 mm ntawm 1 m lub ntsej muag thiab tsis pub ntau tshaj 3 ntawm cov pob qij txha. Qhov chaw sib koom ua ke nyob rau hauv lub ntsej muag nplooj ntawv ntawm cov coated panels yuav tsum tau sau nrog muab tshuaj txhuam ntawm cov xim uas tsim nyog.
Ntoo tsis xws luag xws li sab hauv roughness, bruises, tawg mus txog 200 mm nrog rau fused los yog ib nrab fused noj qab haus huv pob qhov rooj raug tso cai nyob rau hauv slats ntawm ntoo boards. Unfused knots thiab qhov los ntawm lawv yuav tsum tau ntim nrog ntoo inserts los yog muab tshuaj txhuam uas lub veneer yuav glued. Txhua yam rot thiab pwm nyob rau hauv lub rooj tsavxwm slats tsis pub.
Nyob rau hauv cov boards uncoated ntawm hom AB thiab B, raws li zoo raws li nyob rau hauv coated boards ntawm hom II, nyob rau hauv cov nplooj ntawv ntawm lub ntsej muag, qhov qhib los ntawm poob pob caus yuav tsum tau sau nrog muab tshuaj txhuam los yog veneer inserts tshaj kua nplaum, kho cov kev taw qhia ntawm fibers thiab xim ntawm cov ntoo.
Ntawm sab nrauv veneers ntawm lub nraub qaum, nrog rau hauv txhua txheej sab hauv, qhov qhib los ntawm cov pob txha poob nrog txoj kab uas hla ntau dua 10 mm yuav tsum tau ntim nrog cov tshuaj txhuam los yog cov veneer ntxig rau cov kua nplaum.
Yuav tsum tsis muaj stains lossis ib qho kua nplaum rau ntawm qhov chaw ntawm daim hlau. Thaum xa cov panels, daim nplaum nplaum, uas koom nrog cov ntu ntawm cov ntawv txiav veneer, yuav tsum tau muab tshem tawm, thiab cov chaw uas nyob hauv qab yuav tsum tau ntxuav.

Moisture, flatness thiab firmness

Ntawm sab nraub qaum ntawm daim hlau, khawb thiab tawg, tshwm sim los ntawm tev lossis txiav, raug tso cai txog 300 mm, siab tshaj 2 pcs. ntawm 1 m2 daim hlau, nrog rau cov indentations thiab impressions los ntawm lwm daim hlau mus txog 100 mm.

Cov av noo ntawm cov ntoo ntoo yuav tsum yog 8 ± 2 %. Permissible defects teev nyob rau hauv lub rooj. 11.

Carpentry boards yuav tsum tau ua kom ruaj khov. Qhov kawg shear zog ib txheej ntawm cov kua nplaum nyob rau hauv qhuav lub xeev yuav tsum tsis txhob tsawg tshaj li10 kg/cm2. Cov ntaub ntawv ntawm qhov kawg ntawm lub zog ntawm cov phiaj yog muab rau hauv tab.12.

Cov kev cai keeb kwm rau lub hom phiaj tshwj xeeb thiab kev kuaj xyuas

Carpentry boards npaj siv rau hauv kev tsim cov wagons yuav tsum tau impregnated nrog qee tus neeg tiv thaiv hluav taws. Carpentry panels raug xam hauv m3 nrog qhov tseeb 0,001 m3. Cov phaj ua tiav raug xam, ntxiv rau, hauv m2 nrog qhov tseeb txog 0,01 m2.

Ntoo boards raug kuaj rau cov av noo, qhov kawg shear zog rau ib txheej ntawm cov kua nplaum thiab qhov kawg static dabtsi yog khoov zog.

Cov chav kawm, qhov ntev, qhov ntev, qhov ntev thiab qhov tseem ceeb tau raug xa mus los ntawm cov ntaub ntawv keeb kwm thiab yuav tsum tsis txhob siv los hloov cov lus tshaj tawm cov khoom tam sim no, tus qauv siv tau, tsim los yog xam load. Kev xaiv ntawm lub rooj tsavxwm thiab cov nplaum yuav tsum xav txog lub hom phiaj, noo noo, emissions, kev xav tau hluav taws thiab kev ua haujlwm, thiab txiav thiab xuab zeb yuav tsum tau tswj cov plua plav, cov cuab yeej tsim nyog thiab kev tiv thaiv tus kheej.
