Taw qhia rau MDF - Nruab nrab ntom Fiberboard
Nov 21, 2022
Taw qhia:
Ib hom ntawm nruab nrab ntom fiberboard (ntoo-raws li vaj huam sib luag). Nyob rau hauv Suav teb, nruab nrab ntom fiberboard yog tsuas yog ua los ntawm kev ua liaj ua teb residues los yog lwm yam fuelwood, thiab nws lub ntsiab Cheebtsam yog ntoo fiber, resin kua nplaum, thiab lwm yam. ib puag ncig-phooj ywg hloov cov rooj tog thiab cov khoom siv hauv tsev los hloov cov cav. Nws cov txiaj ntsig tseem ceeb yog tus nqi qis, kev ua haujlwm yooj yim, cov khoom siv tsis sib xws, kev ua haujlwm zoo ntawm lub cev, thiab tsis muaj dej tsis zoo thiab tsis muaj dej pov thawj tom qab ntxiv paraffin thiab lwm yam khoom.
Nws nto yog feem ntau pasted nrog melamine ntawv los yog ntoo veneer. Qhov zoo: kev ua tau zoo ntawm lub cev, cov khoom siv tsis sib xws, tsis muaj teeb meem lub cev qhuav dej, tsis muaj deformation vim ya raws; Lub melamine ntsej muag ntawm lub ntsej muag yog dej-pov thawj, tiv thaiv corrosion, hnav-resistant, kub resistant, thiab tsis xav tau kev kho mob tom qab, thiab muaj tsawg formaldehyde cov ntsiab lus.
Qhov ceev ntawm nruab nrab ceev pawg thawj coj saib yog nruab nrab ntawm cov thawj coj siab thiab ntawm Board Board, uas feem ntau 440 ~ 880kg / m³.
Qhov kev qhia tshwj xeeb yog 2440mm * 1220mm, thiab lub thickness yog 3mm, 5mm, 9mm, 12mm, 15mm, 18mm, 25mm, thiab lwm yam. Koj tuaj yeem kho lwm yam tshwj xeeb specifications, thickness ntawm MDF.
Cov yam ntxwv ntawm MDF:
1. Cov ntaub ntawv tsis zoo, cov qauv coj tau ntom ntom, cov npoo, tsis yooj yim rau deform, cov npoo yog qhov yooj yim rau kev ua kom du thiab huv, tsis yooj yim rau kev vau thiab delamination; Nws yog non-toxic, tasteless, tsis muaj hluav taws xob thiab muaj huab cua permeability zoo;
2. Kev ua haujlwm zoo thermal rwb thaiv tsev, tsis muaj kev laus thiab muaj zog adhesion;
3. Lub zog khoov zoo li qub, lub zog tensile, cov ntsiab lus dej, ntsia hlau tuav lub zog, qhov nqus dej nthuav dav, cov ntsiab lus formaldehyde thiab lwm yam ntsuas tau zoo dua li GB / T11718-1999 thiab GBl8580-2001 lub teb chaws tus qauv (sab hauv qauv lub zog ncav cuag 0.74Mpa, cov dej nqus thickness nthuav dav tsawg dua 3 feem pua, thiab cov ntsiab lus dej yog li 5 feem pua).
4. Qhov nruab nrab ntom ntom fiberboard yog qhov muag heev dua li cov chipboard zoo tib yam, nrog kev ua tiav, tsis muaj pob thiab tsis muaj txheej txheej, uas tuaj yeem txo qhov kev siv cov ntaub ntawv zoo heev. Qhov nruab nrab ntom ntom fiberboard yog xaiv los kuaj xyuas formaldehyde emission thiab lub zog ntawm cov qauv. Medium density fiberboard muab faib ua E1, E2 thiab E0 raws li formaldehyde emission. Formaldehyde emission feem ntau tsis tshaj 30mg/100g thiab suav tias yog tsim nyog. Hauv kev tsim piano, E1 thiab E0 yog siv.
5. Cov ntaub ntawv muaj xws li ntoo thuv, poplar, eucalyptus, thiab lwm yam. Nyob rau hauv Tuam Tshoj, MDF yog ib yam khoom zoo rau kev tsim rooj tog thiab kho kom zoo nkauj hauv tsev.
Qhov zoo ntawm MDF:
Qhov saum npoo ntawm lub rooj zaum ntom yog qhov chaw du thiab tiaj tus, cov khoom siv tau ruaj khov, qhov kev ua tau ruaj khov, thiab cov cuab yeej zoo nkauj ntawm pawg thawj coj yog qhov zoo. Txawm li cas los xij, qhov dej tsis kam ntawm lub rooj tsav xwm ceev yog qhov tsis zoo. Nyob rau hauv sib piv, tus ntsia thawv tuav quab yuam ntawm lub rooj tsavxwm ceev yog phem dua li ntawm cov chipboard. Yog tias cov ntsia hlau tau xoob tom qab tau nruj, nws yog qhov nyuaj los kho lub rooj tsav xwm ceev dua vim nws lub zog qis.
1. Lub rooj tsav xwm ceev yog yooj yim ua kom tiav. Txhua yam txheej txheej thiab cov xim tuaj yeem sib npaug rau ntawm lub rooj tsavxwm ntom ntom, uas yog qhov nyiam substrate rau cov nyhuv xim.
2. Lub rooj tsav xwm ceev kuj yog lub rooj tsav xwm zoo nkauj zoo nkauj.
3. Txhua yam ntoo veneer, nplaum nplaum zaj duab xis, vaj huam sib luag zoo nkauj, lub teeb hlau ntawv, melamine board thiab lwm yam ntaub ntawv tuaj yeem muab tso rau ntawm qhov ntom ntom ntom ntom ntom.
4. Lub rooj tsavxwm nyuaj kuj tuaj yeem ua rau lub suab nqus board tom qab xuas nrig ntaus thiab drilling, thiab tuaj yeem siv rau hauv kev kho kom zoo nkauj engineering ntawm cov tsev.
5. Kev ua tau zoo ntawm lub cev, cov khoom siv tsis sib xws, tsis muaj teeb meem lub cev qhuav dej.
Kev yuav khoom ntawm nruab nrab ntom board:
1).Ekev tiv thaiv
Raws li lub teb chaws tus qauv, boards ceev yuav muab faib ua E1 thiab E2 raws li lawv cov ntsiab lus dawb formaldehyde. Lub emission ntawm E2 formaldehyde tsawg dua los yog sib npaug rau 5mg / L; E1 formaldehyde emission tsawg dua lossis sib npaug li 1.5mg / L, uas tuaj yeem siv ncaj qha rau kev kho kom zoo nkauj sab hauv tsev. Thaum yuav cov boards ntom ntom, cov neeg siv khoom yuav tsum sim yuav cov khoom uas tsis muaj formaldehyde emissions, uas muaj kev nyab xeeb dua.
Cov pore xiav qhov luaj li cas ntawm {{0}}.27 nm mus rau 0.98 nm, qhia txog kev teeb tsa siv lead ua. Nyob rau tib lub sijhawm, nws muaj hluav taws xob tsis muaj zog. Cov kab mob molecular ntawm formaldehyde, ammonia, benzene, toluene thiab xylene yog tag nrho ntawm 0.4 thiab 0.62 nm, thiab lawv yog polar molecules. Nws muaj cov yam ntxwv ntawm kev nyiam adsorbing cov pa phem xws li formaldehyde, benzene thiab TVOC, thiaj li ua tiav cov txiaj ntsig ntawm purifying huab cua sab hauv tsev.
2).Zoo
Deg huv: saum npoo ntawm lub chaw tuab neeg nrog kev huv si huv si yuav tsum tsis muaj qhov pom tseeb. Cov khoom yog tshwm sim los ntawm impurities coj los rau hauv cov txheej txheem nias, uas tsis tsuas yog cuam tshuam rau cov tsos, tab sis kuj ua rau cov xim zaj duab xis yooj yim tev tawm.
Deg smoothness: thaum kov lub npoo ntawm tes, nws yuav tsum xav tias du. Yog tias nws hnov astringent, nws txhais tau hais tias qhov kev ua haujlwm tsis nyob hauv qhov chaw.
Nto flatness: nto ntawm lub rooj tsavxwm ntom ntom yuav tsum ci thiab tiaj tus. Yog tias qhov chaw tsis tiaj tus los ntawm sab, nws qhia tau tias muaj teeb meem nrog cov khoom siv lossis txheej txheej txheej.
Zuag qhia tag nrho elasticity: cov boards nyuaj yuav tsum yog cov khoom tsis zoo.
