MDF thiab chipboard - lawv txawv li cas thiab qhov twg zoo dua? Cov lus nug zoo li niaj zaus ntsib los ntawm ob tus kws tshaj lij kev tsim khoom thiab cov neeg yuav khoom qub uas xav hloov kho sab hauv. Tseeb tiag, rau tus neeg tsis tau npaj ua ntej, kev kawm txog lo lus nug ntawm cov khoom siv rau rooj tog twg yog qhov muaj zog dua thiab zoo nkauj zoo nkauj zoo li nyuaj. Cov ncauj lus ntxaws ntxaws ntawm cov chipboards no yuav pab koj nkag siab txhua yam, ntsuas qhov pom kev sib txawv thiab qhov sib txawv ntawm cov yam ntxwv.

Nws yog dab tsi?

Kev nplua nuj ntawm cov khoom siv ntoo ntawm kev muag dawb tso cai rau koj nthuav dav ntau yam ntawm cov khoom siv sab hauv uas ua los ntawm cov laug cam. Cov rooj tog ua los ntawm MDF thiab chipboard yog qhov pheej yig dua li cov khoom zoo sib xws los ntawm cov khoom ntoo; nws tuaj yeem muaj ntau yam teeb tsa thiab tsim qauv xaiv . Tab sis yog tias koj xav tau xaiv ib qho ntawm cov ntaub ntawv, ntau cov lus nug tshwm sim uas tsis cuam tshuam nrog lawv cov nqi. Txhawm rau nkag siab txhua yam, koj yuav tsum paub ntau ntxiv txog txhua qhov kev xaiv.

MDF

Lub npe MDF yog lus Lavxias txhais cov lus Askiv ntawm Medium Density Fibreboard, uas txhais tau tias yog lub rooj sib dhos nruab nrab ntawm cov ntoo fiber ntau. Cov khoom siv no yog tsim los ntawm cov khoom tawg yooj yim los ntawm kev nias qhuav . Hauv kev tsim khoom, siv cov nplaum lignin ntuj los yog paraffin siv, uas ua rau nws muaj peev xwm ua kom muaj kev nyab xeeb ib puag ncig ntawm cov laug cam tiav.

Cov ntaub ntawv tiav tau txais lub zog siab, ntom ntom thiab tawv tawv piv rau ntoo ntuj. Thaum lub sijhawm tsim khoom, tuaj yeem ua tiav ntxiv txhawm rau txhim kho kev tiv thaiv kab mob, tiv thaiv hluav taws, tiv taus ya raws.

Cov txheej txheem ntawm kev ua lub rooj tsavxwm muaj ntau txoj hauv kev zoo ib yam li ua ntawv . Cov ntaub ntawv raw - ntoo fibers - tau ua tib zoo ua kom zoo, uas ua rau nws muaj peev xwm siv ntau hom pov tseg hauv kev tsim khoom. Kev faib ua feem ua ntej tau raug ntxuav los ntawm cov pa, qhov hnyav dhau los sib tsoo ntxiv hauv cov tshuab tshwj xeeb, tom qab ntawd nws tau qhuav, pwm, thiab kub nias. Cov khoom siv tau txais lub zog piv rau cov yam ntxwv ntawm cov ntoo ntuj, qhov ntom ntom thiab ruaj khov, qiv nws tus kheej rau yuav luag txhua hom kev ua.

Lub hauv paus tseem ceeb ntawm kev thov MDF yog cov rooj tog tsim khoom; cov laug cam tsis siv rau kev tsim kho xav tau, txij li muaj lwm txoj hauv kev, xaiv tau ntau dua.

Chipboard

Cov khoom siv no, siv feem ntau hauv cov rooj tog tsim khoom, yog qhov raug hu ua chipboard - chipboard, tab sis qhov kev teev npe tsis raug nyam raws li lub npe lag luam. Qhov tseeb, chipboard yog cov ntawv sib xyaw ua ke uas muaj cov quav nrog nruab nrab thiab nplua me me . Nws yog tsim los ntawm kub nias los ntawm cov ntoo sawdust, ntxiv cov phenolic-based binder thiab qee lwm yam khoom siv uas ua rau kom muaj zog ntawm kev sib txuas.

Cov ntawv tiav yog raug rau kev ua ntxiv . Qhov no tuaj yeem ua rau saum npoo av, lamination lossis lamination - qhov kawg 2 qhov kev xaiv raug txiav txim siab zoo nkauj.

Lub cheeb tsam tseem ceeb ntawm daim ntawv thov ntawm laminated chipboard yog cov rooj tog tsim khoom - nws tau siv hauv kev tsim cov txheej txheem hull . Cov khoom siv polished ua lub hauv paus rau kev tsim cov ntim ntim rau kev thauj khoom, rau kev faib khoom thiab phab ntsa cladding hauv kev tsim kho.

Particleboard yog thawj cov khoom tso tawm los ntawm cov khoom ntoo . Nws cov khoom lag luam tau tsim los txij li 30s ntawm lub xyoo pua XX, niaj hnub no cov ntawv txheeb tau suav tias yog ib qho ntawm cov khoom pheej yig tshaj plaws ntawm cov tsev tsim vaj tsev, tsim tawm hauv kaum ob lub tebchaws thoob ntiaj teb.

Peb tuaj yeem hais tias chipboards yog qhov kev xaiv loj heev, thaum MDF tuaj yeem raug ntaus nqi rau cov khoom muaj npe zoo dua.

Qhov sib txawv tseem ceeb

Qhov ntsuas tseem ceeb uas MDF txawv ntawm chipboard yog tshuab siv los ua slabs . Qhov sib txawv ntawm cov zauv yog pom rau qhov muag liab qab: hauv ib kis, nws tsis yog ib txwm sib xyaw sawdust, hauv lwm qhov, nws yog cov tuab tuab, ntau dua li ntoo. MDF yog cov khoom siv uas tuaj yeem sib txawv tau yooj yim los ntawm nws cov qauv sib xws, kev du nto, thiab ntom ntom.

Qhov txiaj ntsig tseem ceeb ntawm chipboard yog nyob rau hauv tus nqi, cov laug cam ntawm hom no muaj ntau dua thiab pheej yig dua, tom qab lamination ntawm qhov chaw lawv tau txais qhov zoo nkauj zoo nkauj. MDF yog kim dua, tab sis zoo nkauj dua; nws tuaj yeem tsim ua thiab ua milled.

Kev sib piv ntxaws ntxiv tso cai rau lwm qhov sib txawv los txheeb xyuas. Piv txwv li, Cov khoom siv ntoo tuaj yeem muab rau chav kawm tso tawm E2, E3, E4, uas yog, nws muaj cov tshuaj phom sij thiab cov tshuaj formaldehyde uas txwv tsis pub siv sab hauv lossis hauv cov khoom siv rooj tog . Yog tias lub chaw tsim khoom tsis raug cai txiav txim siab txuag nyiaj, muaj qhov tshwm sim siab ntawm kev ua phem rau tib neeg kev noj qab haus huv. Hauv qhov kev nkag siab no, MDF cov laug cam muaj kev nyab xeeb dua, lawv ib txwm yog chav kawm E1 tso tawm, uas tsis muaj kev phom sij rau tib neeg.

Pom

Hauv cov rooj tog tiav, MDF thiab chipboard tau hais tawm qhov muag sib txawv. Yog li, chipboard tau siv ntawm no nyob rau hauv daim ntawv laminated lossis laminated, nrog rau txheej zoo nkauj, thiab tsuas yog tsim lub cev qauv - thav duab, daim iav, cov rhawv zeb . Cov khoom siv loj heev uas tsis tshua muaj siv hauv lub ntsej muag vim nws qhov hnyav thiab tsis yog cov khoom zoo nkauj tshaj plaws.

Qhov xoob ntawm cov laug cam ntoo kuj yog teeb meem loj. Feem ntau, cov rooj tog zoo li no tsis zam kev rov sib sau ua ke, rov ua dua cov ntsia hlau txuas ntxiv, thiab yog tias koj sim ua cov txheej txheem zoo, koj tuaj yeem tau txais daim tawv nqaij thiab qhov tsis xws luag ntawm lub hauv ntej npog.

Qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom siab ntawm MDF tso cai rau cov khoom siv no ua kom yooj yim: raws li cov khoom no, lub rooj tsav khoom tiav yog nyob ze ntawm cov ntoo . Cov ntawv tuaj yeem txiav ncaj thiab nkhaus, milled, txiav. Cov nplais yog siv los ua cov rooj tog zaum zoo nkauj nrog cov qauv, pwm, platbands. Toning kuj tseem ua tiav hauv kev tsim khoom, tag nrho pawg ntawm qhov txiav muaj qhov ntxoov ntxoo ib yam. Kev kho kom zoo nkauj tuaj yeem yog txhua yam - los ntawm staining mus rau thov kev ntxhib los mos, tsis xav tau xuab zeb ua ntej ua ntej ua tiav cov vuas.

Thaum nws los txog rau xaiv txheej txheej sab nrauv, MDF kuj tseem muaj qhov kom zoo dua qub . Cov khoom tuaj yeem tso tseg yooj yim sanded, npog nrog PVC-based zaj duab xis cov ntaub ntawv, veneered lossis pleev xim nrog txha hniav laus hauv qhov ci, ua tiav.

Nyob rau hauv txhua rooj plaub, txheej yuav dhau los ua cov dej noo tiv taus, nws yuav pw zoo thiab zoo ib yam ntawm cov phaj.

Hauv cov yam ntxwv

Kev sib piv ntawm tus yam ntxwv tseem qhia qhov sib txawv ntawm cov khoom siv. Ntawm qhov ntsuas tseem ceeb tshaj plaws yog cov hauv qab no.

1. Lub zog . Nov yog tus thawj coj pom tseeb yog MDF, nws muaj zog dua vim yog qhov tshwj xeeb ntawm kev tsim khoom - homogeneity ntawm cov zauv ua rau cov khoom muaj zog dua, kev sib koom ua ke ntawm tus kheej cov ntsiab lus yog siab dua. Cov khoom siv ntoo yog sib txawv ob qho tib si hauv kev sib xyaw thiab qhov loj ntawm cov khoom siv. Nyob ntawm tus txheej txheem txheej txheem (nias nrawm, ntim ntawm cov phau ntawv ntxiv), cov khoom siv no tuaj yeem dhau los ua qhov muaj zog txaus, tab sis nws ib txwm tsis zoo tsis yog rau cov ntoo xwb, tab sis kuj rau lwm lub rooj vaj tsev.
2. Qhov hnyav . Raws li qhov ntsuas no, MDF yog tus coj - cov laug cam sib zog dua li lawv cov phooj ywg. Ib daim ntawv uas muaj qhov loj ntawm 2800 × 2700 mm yuav hnyav txog 28 kg. Raws li, kev thauj khoom ntawm phab ntsa raug txo qis hauv kev tsim khoom ntawm phab ntsa khoom thiab txee, cov khoom lag luam tsawg dua. Chipboard hnyav dua - kwv yees li 30 kg rau ib daim ntawm 2750 × 1830 mm.
3. Ib puag ncig phooj ywg . Raws li qhov ntsuas no, tsis ntseeg, MDF yog tus coj, uas yog raug rau cov txheej txheem thoob ntiaj teb uas txwv tsis pub siv cov formaldehydes txaus ntshai. Piv txwv li, txhua lub rooj tog MDF tau cim E1, uas yog ib puag ncig zoo dua, thiab E2 tsis tuaj yeem siv tau hauv cov menyuam chav (hauv ntau lub tebchaws nws tsis tsim lawm). Chipboard tau tsim tawm raws li cov qauv sib txawv. Ntawm no, formaldehyde resins yog ib qho tseem ceeb ntawm kev tsim khoom, thiab nws nyuaj rau txheeb xyuas lawv cov ntim.
4. Ceev Txhua MDF cov laug cam muaj cov yam ntxwv zoo hauv qhov ntsuas no, ze rau ntoo ntuj - los ntawm 720 txog 870 km / m3. Raws li, cov khoom tsim nyog rau kev thov thauj khoom. Rau chipboard, qhov ntsuas no txawv, muaj 3 hom ntawm cov laug cam: nrog qis (txog 550 kg / m3), nruab nrab (txog 750 kg / m3) thiab ntom ntom. Qhov kev xaiv zaum kawg yog txiav txim siab rooj tog, tus so - kev tsim kho, tau siv los ua dai phab ntsa cladding, muab faib.
5. Hws noo kuj . Classic sanded chipboard muaj peev xwm nqus dej, nce txog 30% ntawm qhov ntim thawj. Tib yam siv rau laminated chipboard, nyob rau hauv uas kaw tsis zoo ntug nce noo noo tsis mob. Vim nws cov high ceev, MDF yog suab devoid ntawm cov drawbacks - txawm tias thaum tag nrho raus rau hauv dej rau ob peb teev, cov khoom tsis hloov nws tsis.

Cov no yog cov yam ntxwv tseem ceeb uas koj tuaj yeem sib piv 2 hom khoom siv hauv cov pob zeb. Thiab ntawm no MDF tuaj yeem hu ua tus thawj coj tsis muaj kev sib cav, txij li cov ntawv txheeb yog cov khoom lag luam siab dua.

Dab tsi zoo dua?

Thaum xaiv cov khoom siv rau kev tsim kho ntawm ib sab hauv tsev, rau kev tsim cov ntxaij vab tshaus zoo nkauj, thaum saib rau rooj tog tsim nyog, koj ib txwm yuav tsum xaiv ntawm ntau hom khoom sib txawv. Tau kawg, yog tias tus qauv tseem ceeb yog kev pheej yig, chipboards tsis muaj cov neeg sib tw ntawm no: lawv muaj nqis thiab saib zoo nkauj heev tom qab thov txheej txheej zoo nkauj. Tab sis muaj qee qhov subtleties. Piv txwv li, qhov kev xaiv no yuav tsis ua haujlwm hauv cov chav nrog cov av noo siab - koj yuav tsum xaiv cov rooj tog thiab cov khoom siv los ntawm lwm cov ntaub ntawv rau chav dej.

MDF yog tus nqi ntau dua, tab sis nws zam qhov teeb meem tsis yog tsuas yog tso tawm cov tshuaj phom sij lossis nqus dej ntau dhau . Cov ntaub ntawv no tso cai rau koj ua kom muaj ntau yam kev tsim cov rooj tog tiav. Piv txwv li, zam lub ntsej muag los yog lub ntsej muag nkhaus rau chav ua noj tuaj yeem tsim los ntawm nws nkaus xwb, lub chipboard ntawm kev txiav nkhaus yuav tsis hloov pauv, nrog rau kev hloov pauv hauv cov duab geometric. Kev txwv cov av noo kuj tsawg heev. MDF tuaj yeem tiv taus qhov nce ntxiv txog li 70%, thiab nrog kev ua tshwj xeeb cov duab no yuav siab dua.

Rau chav ua noj, nws yog qhov zoo dua los xaiv ob hom khoom hauv qhov kim tshaj plaws . Cov phiajcim no muaj cov tshuaj tiv thaiv ya raws ntxiv, cov khoom tiv thaiv hluav taws kom tiv thaiv kev tiv thaiv thaum muaj kev sib cuag nrog hluav taws. Nrog cov tuab tuab, cov txee hauv chav ua noj yuav ua tau zoo ntawm laminated chipboard, tab sis nws yog qhov tsim nyog uas cov ntug tau ua tiav thaum nws tsim khoom. Nws yog qhov zoo dua los siv MDF cov laug cam nrog hluav taws-resistant impregnation thiab zoo nkauj zaj duab xis txheej ntawm lub apron.

Feem ntau cov ntaub ntawv no tau ua ke kom tau txais qhov zoo nkauj dua, tab sis tus nqi pheej yig. Qhov kev xyaum yog suav tias yog thoob plaws thaum cov thav duab ntawm cov txee hauv chav ua noj yog ua los ntawm cov khoom siv ntoo, thiab lub ntsej muag – los ntawm ib phaj ntawm qhov nruab nrab ntom ntom . Txawm li cas los xij, yog tias pob nyiaj tso cai, nws zoo dua tam sim muab qhov nyiam rau MDF rooj tog. Hais txog nws cov txiaj ntsig, nws zoo ib yam li ntoo, nws raug nqi ntau dua li nws, thiab nws ua haujlwm ntev.

Cov nplais zoo tshaj plaws tau ua hauv EU lub tebchaws, lawv tau cim E1, muaj kev nyab xeeb kiag li, haum rau txhua thaj chaw hauv tsev - los ntawm cov menyuam chav thiab chav pw mus rau chav dej.
