kev qhia

Cov hniav txiav yog ib qho ntawm cov cuab yeej tseem ceeb uas peb siv hauv kev ua txhua hnub.

Tej zaum koj tsis meej pem txog qee qhov kev ntsuas ntawm cov hniav txiav xws li cov khoom siv thiab cov duab hniav. Tsis paub lawv txoj kev sib raug zoo.

Vim tias cov no feem ntau yog cov ntsiab lus tseem ceeb uas cuam tshuam rau peb cov hniav txiav thiab xaiv.

Raws li cov kws tshaj lij hauv kev lag luam, hauv tsab xov xwm no, peb yuav muab qee cov lus piav qhia txog kev sib raug zoo ntawm cov kev ntsuas ntawm cov hniav pom.

Yuav pab koj nkag siab zoo dua txog lawv thiab xaiv cov hniav pom zoo.

Cov Hom Khoom Siv Feem Ntau

Kev Ua Haujlwm Ntoo: Ntoo Khoom (ntoo ib txwm) Thiab Ntoo Engineered

Ntoo khov khoyog ib lo lus uas feem ntau siv los qhia qhov txawv ntawm cov qubntoo thiab ntoo ua los ntawm cav, tab sis nws kuj hais txog cov qauv uas tsis muaj qhov chaw khoob.

Cov khoom ntoo uas tau tsim los ntawm kev siv tshuabyog tsim los ntawm kev sib txuas ua ke cov ntoo strands, fibers, lossis veneers nrog cov nplaum los ua cov khoom sib xyaw. Cov ntoo engineered suav nrog plywood, oriented strand board (OSB) thiab fiberboard.

Ntoo Khoom:

Kev ua cov ntoo puag ncig xws li: fir, poplar, ntoo thuv, ntoo nias, ntoo txawv teb chaws thiab ntau yam ntoo, thiab lwm yam.

Rau cov ntoo no, feem ntau muaj qhov sib txawv ntawm kev txiav hla thiab kev txiav ntev.

Vim nws yog ntoo khov kho, nws yuav tsum tau tshem tawm cov chips ntau heev rau cov hniav txiav.

Pom zoo thiab kev sib raug zoo:

• Cov Hniav Pom Zoo: cov hniav BC, ob peb tug siv tau cov hniav P
• Hniav Pom: ntau-ripping saw hniav. Khoom ntoo khoom txiav hla-txiav, Longitudinal txiav saw

Ntoo Tsim Kho

Ntoo plywood

Plywood yog cov khoom sib xyaw ua ke uas tsim los ntawm cov txheej nyias nyias, lossis "plies", ntawm cov ntoo veneer uas tau nplaum ua ke nrog cov txheej sib ze, kom lawv cov ntoo tig mus txog 90 ° rau ib leeg.

Nws yog ib hom ntoo uas tau tsim los ntawm tsev neeg ntawm cov laug cam uas tsim tawm.

Cov yam ntxwv

Qhov kev hloov pauv ntawm cov noob no hu ua cross-graining thiab muaj ntau yam txiaj ntsig tseem ceeb:

• nws txo qhov kev nyiam ntawm cov ntoo kom tawg thaum ntsia hlau rau ntawm ntug;
• nws txo qhov kev nthuav dav thiab kev ntsws, muab kev ruaj khov zoo dua; thiab nws ua rau lub zog ntawm lub vaj huam sib luag sib xws thoob plaws txhua qhov kev taw qhia.

Feem ntau muaj tus lej khib ntawm cov plies, yog li ntawd daim ntawv thiaj li sib npaug - qhov no txo ​​​​​​kev warping.

Cov Rooj Sib Tham Particle

Cov khoom siv particle board,

tseem hu ua particleboard, chipboard, thiab low-density fiberboard, yog cov khoom ntoo tsim los ntawm cov ntoo chips thiab cov khoom siv hluavtaws lossis lwm yam khoom siv uas tsim nyog, uas tau nias thiab extruded.

Feature

Particle board pheej yig dua, denser thiab sib xws duadua li cov ntoo thiab plywood ib txwm muaj thiab raug hloov rau lawv thaum tus nqi tseem ceeb dua li lub zog thiab tsos.

MDF

Cov fiber ntau nruab nrab (MDF)

yog ib yam khoom ntoo uas ua los ntawm kev rhuav cov tawv ntoo lossis cov ntoo mos ua cov ntoo fiber, feem ntau hauv lub tshuab defibrator, sib xyaw nrog cov quav ciab thiab cov khoom siv resin, thiab tsim nws rau hauv cov vaj huam sib luag los ntawm kev siv qhov kub thiab siab.

Nta:

MDF feem ntau yog denser dua li plywood. Nws yog ua los ntawm cov fiber sib cais tab sis tuaj yeem siv ua cov khoom siv hauv tsev zoo ib yam li plywood. Nws yogmuaj zog dua thiab ntom duatshaj li cov particle board.

Kev sib raug zoo

• Cov duab hniav: Nws raug pom zoo kom xaiv cov hniav TP. Yog tias MDF ua tiav muaj ntau yam tsis huv, koj tuaj yeem siv cov hniav TPA zoo li hniav.

Kev Txiav Hlau

• Cov ntaub ntawv siv ntau: cov hlau tsis tshua muaj hlau, cov hlau nruab nrab thiab cov hlau tsis tshua muaj carbon, hlau cam khwb cia, cov hlau qauv thiab lwm yam hlau uas muaj qhov nyuaj hauv qab HRC40, tshwj xeeb tshaj yog cov hlau modulated.

Piv txwv li, hlau puag ncig, hlau kaum sab xis, hlau kaum sab xis, hlau channel, raj plaub fab, I-beam, txhuas, yeeb nkab hlau tsis xeb (thaum txiav yeeb nkab hlau tsis xeb, daim ntawv hlau tsis xeb tshwj xeeb yuav tsum tau hloov)

Cov yam ntxwv

Cov ntaub ntawv no feem ntau pom muaj nyob rau ntawm qhov chaw ua haujlwm thiab hauv kev lag luam kev tsim kho. Kev tsim tsheb, kev tsav dav hlau, kev tsim tshuab thiab lwm yam.

• Kev Ua HaujlwmTsom ntsoov rau kev ua haujlwm tau zoo thiab kev nyab xeeb
• Cov hniav txiavTug: Qhov zoo tshaj plaws los txiav txim siab seb puas yog qhov txiav txim siab zoo tshaj plaws los yog qhov txiav txim siab zoo tshaj plaws

Cov Lus Qhia Txog Kev Siv Thiab Kev Sib Raug Zoo

Thaum peb xaiv cov ntaub ntawv, muaj ob qho tseem ceeb uas yuav tsum tau them sai sai.

1. Khoom siv
2. Khoom Siv Thickness

• Tus taw tes 1 txiav txim siab hom hniav txiav ntxhib thiab cov txiaj ntsig ntawm kev ua haujlwm.

• Qhov 2 yog txuas nrog rau sab nraud txoj kab uas hla thiab tus naj npawb ntawm cov hniav ntawm cov hniav txiav.

Qhov tuab dua, qhov loj dua ntawm sab nraud. Cov mis ntawm lub hniav pom sab nraud

Yuav pom tau tias:

Lub cheeb tsam sab nraud ntawm cov hniav pom = (qhov tuab ntawm kev ua haujlwm + qhov tso cai) * 2 + txoj kab uas hla ntawm lub flange

Lub caij no, Cov khoom siv nyias dua, cov hniav ntau dua. Qhov ceev ntawm kev pub mis yuav tsum qeeb qeeb.

Kev sib raug zoo ntawm cov hniav zoo li cas thiab cov khoom siv

Vim li cas koj thiaj yuav tsum xaiv cov hniav zoo li cas?

Xaiv cov hniav zoo thiab qhov ua tiav yuav zoo dua. Zoo dua phim cov khoom koj xav txiav.

Kev Xaiv Cov Duab Hniav

1. Nws muaj feem cuam tshuam nrog kev tshem tawm cov chips. Cov ntaub ntawv tuab xav tau cov hniav me me, uas yog qhov zoo rau kev tshem tawm cov chips.
2. Nws muaj feem cuam tshuam rau qhov cuam tshuam ntawm qhov seem. Cov hniav ntau npaum li cas, qhov seem du dua.

Cov hauv qab no yog kev sib raug zoo ntawm qee cov ntaub ntawv siv thiab cov duab hniav:

BC HniavFeem ntau yog siv rau kev txiav hla thiab txiav ntev ntawm cov ntoo khov kho, cov laug cam ntom ntom, cov yas, thiab lwm yam.

TP HniavFeem ntau yog siv rau cov vaj huam sib luag ob chav veneer tawv, cov hlau tsis yog ferrous, thiab lwm yam.

Rau cov ntoo khov kho, xaivCov hniav BC,

Rau cov hlau txhuas thiab cov laug cam cuav, xaivCov hniav TP

Rau cov laug cam cuav uas muaj ntau yam tsis huv, xaivTPA

Rau cov laug cam uas muaj veneers, siv lub tshuab txiav kom txiav ua ntej, thiab rau cov plywood, xaivB3C los yog C3B

Yog tias nws yog cov khoom siv veneered, feem ntau xaivTP, uas tsis tshua muaj feem yuav tawg.

Yog tias cov khoom muaj ntau yam impurities,TPA los yog T hniavfeem ntau raug xaiv los tiv thaiv cov hniav tawg. Yog tias cov khoom tuab loj, xav txog kev ntxivG(lub kaum sab xis ntawm lub rake) rau kev tshem tawm cov chips zoo dua.

Kev Sib Raug Zoo Nrog Lub Tshuab:

Lub laj thawj tseem ceeb rau kev hais txog cov tshuab yog tias qhov peb paub tias yog lub hniav txiav yog ib qho cuab yeej.

Lub hniav txiav thaum kawg yuav tsum tau teeb tsa rau ntawm lub tshuab rau kev ua tiav.

Yog li ntawd, qhov peb yuav tsum tau them sai sai rau ntawm no yog. Lub tshuab rau lub hniav txiav uas koj xaiv.

Tsis txhob pom lub hniav txiav thiab cov khoom siv uas yuav tsum tau ua. Tab sis tsis muaj tshuab los ua nws.

Xaus lus

Los ntawm cov saum toj no, peb paub tias cov khoom siv kuj yog ib qho tseem ceeb uas cuam tshuam rau kev xaiv cov hniav pom.

Kev ua ntoo, ntoo khov kho, thiab cov vaj huam sib luag uas tib neeg ua txhua yam muaj ntau yam sib txawv. Cov hniav BC feem ntau yog siv rau cov ntoo khov kho, thiab cov hniav TP feem ntau yog siv rau cov vaj huam sib luag.

Cov khoom siv tuab thiab cov khoom siv kuj muaj feem cuam tshuam rau cov duab hniav, txoj kab uas hla sab nraud ntawm cov hniav pom, thiab txawm tias kev sib raug zoo ntawm lub tshuab.

Los ntawm kev nkag siab txog cov no, peb tuaj yeem siv thiab ua cov ntaub ntawv zoo dua.

Yog tias koj xav paub ntxiv, peb tuaj yeem muab cov cuab yeej zoo tshaj plaws rau koj.
