Qhov zoo tshaj plaws kev cai loj rooj tog melamine ya raws pov thawj thiab waterproof MDF

MDF muaj nuj nqis rau nws qhov tsis muaj qhov tsis xws luag thiab muaj qhov sib xws zoo heev uas tso cai rau nws txiav, rout, duab thiab laum kom huv si, tuav cov ntsiab lus sib txawv nrog tsawg kawg ntawm cov pov tseg thiab cov cuab yeej hnav.Vaj huam sib luag rau vaj huam sib luag, nws yog ib qho nyuaj rau yeej rau cov khoom efficiency, machining kev ua tau zoo thiab tsim tau.MDF kuj ua tiav zoo nkauj thiab tsis tu ncua.Nws tiaj tus, du nto muab cov txiaj ntsig tshwj xeeb txawm tias laminated, luam tawm ncaj qha lossis pleev xim.Sanded nrog ntau yam muaj grits, nws ua tau zoo txawm tias nyias nyias thiab xim xim tsaus.Dimensional stability yog lwm qhov txiaj ntsig tseem ceeb.Qhov ntawd txhais tau tias o thiab thickness variations yog zoo tshem tawm thaum siv cov khoom no.Lub tshuab craftsmen precision rau hauv lawv cov khoom siv thaum lub sij hawm tsim khoom yuav raug tswj xyuas hauv cov khoom sib dhos uas lawv tsim.Fasteners yuav nruj thiab cov neeg siv kawg yuav txaus siab rau qhov haum thiab huv si.
Muab lub ntsej muag du, zoo ib yam uas tsis muaj qhov tsis xws luag
High-quality, high-energy-refined fibers thiab zoo ib yam ntom ntom ntawm Ultrastock xaiv muab cov yam ntxwv zoo tshaj plaws los txiav thiab ua kom huv.
Smooth nto polished nrog qhov kawg 150 grit tiav
Zoo kawg nkaus haum rau cov xim, stains, veneers lossis laminates-tag nrho nrog cov txiaj ntsig zoo
Tsis xav tau kev sib dhos

Nyob rau tib lub sijhawm, lo lus "MDF" tau dhau los ua lub npe dav dav rau txhua qhov kev ua haujlwm fiber ntau.MDF feem ntau yog ua los ntawm 82% ntoo fiber, 9% urea-formaldehyde resin kua nplaum, 8% dej, thiab 1% paraffin wax.Qhov ceev yog feem ntau ntawm 500 thiab 1,000 kg / m3 (31 thiab 62 lb / cu ft). Qhov ntau ntawm qhov ceev thiab kev faib tawm raws li lub teeb-,, lossis lub rooj tsavxwm muaj zog siab yog qhov tsis zoo thiab tsis meej pem.Qhov ceev ntawm lub rooj tsavxwm, thaum ntsuas qhov sib txawv ntawm qhov ntom ntawm cov fiber ntau uas nkag mus rau hauv kev ua vaj huam sib luag, yog qhov tseem ceeb.Ib pawg tuab me mdf ntawm qhov ntom ntawm 700-720 kg / m3 (44-45 suav tias yog li ntawd.Kev hloov pauv ntawm ntau hom MDF tau tsav los ntawm kev xav tau sib txawv rau cov ntawv thov tshwj xeeb.
Thaum MDF raug txiav, ib qho loj ntawm cov hmoov av tawm mus rau saum huab cua.Lub tshuab ua pa yuav tsum tau hnav thiab cov khoom txiav hauv qhov chaw tswj thiab qhov cua.Sealing exposed npoo yog ib qho kev coj ua zoo los txwv cov emissions los ntawm binders uas muaj nyob rau hauv cov khoom no.
Formaldehyde resins feem ntau yog siv los khi ua ke cov fibers hauv MDF, thiab kev ntsuam xyuas tau qhia tsis tu ncua tias MDF cov khoom emit dawb formaldehyde thiab lwm cov organic tebchaw uas ua rau muaj kev phom sij rau kev noj qab haus huv ntawm cov concentrations suav tias tsis zoo, tsawg kawg ob peb lub hlis tom qab tsim.Urea-formaldehyde yog ib txwm tau maj mam tso tawm ntawm cov npoo thiab nto ntawm MDF.Thaum pleev xim, txheej txhua sab ntawm cov khoom tiav yog ib qho kev coj ua zoo los muab khi rau hauv cov dawb formaldehyde.Wax thiab roj tiav tuaj yeem siv ua tiav, tab sis lawv tsis tshua muaj txiaj ntsig ntawm kev sib khi hauv cov dawb formaldehyde.
Txawm hais tias cov emissions tas li ntawm formaldehyde mus txog theem teeb meem hauv lub ntiaj teb ib puag ncig tiag tiag tseem tsis tau txiav txim siab tag nrho.Qhov kev txhawj xeeb tseem ceeb yog rau kev lag luam uas siv formaldehyde.Raws li deb rov qab rau xyoo 1987, Tebchaws Asmeskas EPA tau suav tias yog "qhov tshwm sim ntawm tib neeg carcinogen", thiab tom qab kev tshawb fawb ntau ntxiv, WHO International Lub Koom Haum rau Kev Tshawb Fawb Txog Kev Tshawb Fawb (IARC), xyoo 1995, kuj tau faib nws ua "qhov tshwm sim tib neeg carcinogen".Cov ntaub ntawv ntxiv thiab kev ntsuam xyuas ntawm tag nrho cov ntaub ntawv paub tau ua rau IARC rov faib cov formaldehyde raws li "cov neeg paub txog carcinogen" txuam nrog rau qhov ntswg qhov ntswg thiab mob qog noj ntshav nasopharyngeal, thiab tej zaum yuav muaj leukemia thaum Lub Rau Hli 2004.
Raws li International Composite Board Emission Standards, peb European formaldehyde chav kawm yog siv, E0, E1, thiab E2, raws li kev ntsuas ntawm formaldehyde emission theem.Piv txwv li, E0 raug cais raws li muaj tsawg dua 3 mg ntawm formaldehyde tawm ntawm txhua 100 g ntawm cov kua nplaum siv hauv particleboard thiab plywood fabrication.E1 thiab E2 raug cais raws li muaj 9 thiab 30 g ntawm formaldehyde ib 100 g ntawm kua nplaum, raws li.Tag nrho ib ncig ntawm lub ntiaj teb no, cov ntawv pov thawj sib txawv thiab cov ntawv sau npe muaj nyob rau hauv cov khoom lag luam uas tuaj yeem qhia meej rau formaldehyde tso tawm, xws li Californian Air Resources Board.
