Kev txhim kho niaj hnub ntawm cov txheej txheem thev naus laus zis tso cai rau peb muab cov neeg siv ntau yam khoom tsim thiab ua tiav. MDF board yog ib qho khoom siv uas siv rau cov khoom siv thiab hauv kev tsim cov rooj tog. Xav txog cov yam ntxwv thiab cov yam ntxwv ntawm cov khoom no.
History of Creation
MDF lub rooj tsavxwm tau tsim nyob rau hauv Tebchaws Meskas (li rau caum xyoo ntawm lub xyoo pua 20th). Cov ntawv luv luv tuaj yeem txhais raws li hauv qab no: nruab nrab ntom ntom fiberboard. Cov khoom siv yog tsim los ntawm cov ntoo, uas yog xyaum hauv av mus rau qhov tsawg tshaj plaws fibers. Qhov kev tsim no tsis ua mob rau hav zoov, vim kev siv cov khib nyiab ntoo feem ntau yog siv.
Cov khoom siv rov ua dua yog ntxuav ntawm cov xuab zeb thiab lwm yam txawv teb chaws suav nrog. Tom qab ntawd cov khoom npaj tau raug ntxuav kom huv si thiab qhuav. Tom qab ntawd lub loj yog rhuab thiab ib daim kab xev ntawm yuav tsum tau thickness thiab dav yog tsim los ntawm nws nrog ntxiv nias. Nyob rau hauv lub siab, ib tug binder ntawm lub hauv paus chiv keeb (Lignin) raug tso tawm los ntawm lub Cheebtsam. Cov khoom lag luam tau txais nws qhov kev teeb tsa zaum kawg tom qab huab cua tau tso tawm, sawv cev rau cov qauv sib xws hauv daim ntawv ntawm MDF board.
Ntse
Tom qab cov txheej txheem niascov khoom yog ua tiav, tom qab uas cov khoom uas twb muaj lawm raug tshem tawm thiab nws yog coj mus rau qhov yuav tsum tau qhov ntev. Nws yuav tsum raug sau tseg tias tsis yog txhua hom ntoo tsim cov txiaj ntsig tsim nyog. Hauv qhov no, lignin lossis nws cov analogues ntxiv.
Ntawm cov ntaub ntawv, MDF pawg thawj coj saib yog qhov kev nyab xeeb tshaj plaws, vim nws muaj qhov tsawg kawg nkaus ntawm formaldehyde. Cov menyuam yaus thiab lwm cov rooj tog zaum yog tsim los ntawm cov khoom siv no (tus qauv kev ua raws cai thoob ntiaj teb - F1). Cov txiaj ntsig ntxiv yog cuam tshuam nrog kev tiv thaiv kom ya raws thiab hluav taws.
Ib daim ntawv
Nyob rau hauv nws daim ntawv ntuj, cov khoom suav hais tias muaj xim xim av nrog greyish tint, thiab homogeneous ntom ntom yog pom ntawm qhov txiav. Cov xim kawg yog nyob ntawm hom ntoo hauv av thiab tus nqi ntawm cov tawv ntoo. Cov phab ntsa MDF no yog qhov zoo rau kev tsim ntau hom kev faib tawm hauv kev tsim kho thiab rooj tog kev lag luam.
Qhov chaw ua haujlwm tuaj yeem txhim kho ntxiv los ntawm kev pasting nrog veneer, lamination, thiab PVC zaj duab xis. Qhov kev daws teeb meem no tso cai rau koj kom tau txais txiaj ntsig siv cov khoom siv no hauv kev ua haujlwm tiav. Kev tsim cov qauv tsim ua rau nws muaj peev xwm tsim cov khoom ntawm ntau yam duab thiab thicknesses siv rau kev ua tiav, kev tsim cov rooj tog zaum, skirting boards, platbands thiab lwm yam moldings.
Cov qauv ntawm cov khoom hauv nqe lus nug muaj cov fibers me me uas tsim cov plua plav thaum milling. Ntawm lwm yam nta - muaj peev xwm tsim curly facades, hniav grilles thiab cov ntxaij vab tshaus cua sovradiators.
MDF board loj
Kev tsim khoom siv thev naus laus zis ntawm cov khoom siv no tso cai rau koj los kho qhov ceev ntawm thaj tsam ntawm 750 txog 1100 kg / m 2. Cov khoom uas muaj qhov ntsuas qis dua yog siv rau kev ua haujlwm tiav thiab hauv cov rooj tog tsim khoom, thiab cov qauv uas muaj qhov ntom ntom dua yog siv los ua hauv pem teb tiav.
Nyob rau hauv rooj plaub tom kawg, cov khoom yog tus cwj pwm los ntawm kev tiv thaiv kom puas thiab lub zog. Daim phiaj tuaj yeem tsim nrog cov kev txwv hauv qab no:
- Curl ratio - los ntawm 1, 2 mus rau 15 millimeters kab pheeb ces kaum.
- Dav - ntawm 15 txog 120 cm.
- Length - los ntawm 130 txog 260 cm.
- Lub thickness ntawm MDF boards yog los ntawm 3 mus rau 40 hli.
- Qhov txawv ntawm qhov ntom yog los ntawm 0.2 txog 2.5mm.
- Khiav dav / ntev - 2/5 mm.
Nws yog qhov yooj yim los ua haujlwm nrog cov khoom siv tshwj xeeb vim qhov me me khiav hauv qhov ntev. Tsis tas li ntawd, kev sib koom ua ke ntawm cov vuas yog nrawm thiab tsis tas yuav muaj kev hloov kho tshwj xeeb.
Ntog hom
Cov khoom tuaj yeem tsim nrog cov hauv qab no tiav:
- Sanded versions. Lawv tuaj yeem ua tiav ntawm ob lossis ib sab. Cov khoom yog zoo tagnrho rau puttying los yog painting. Yog tias koj siv cov khoom siv rau theem phab ntsa, nws raug nquahu kom siv cov primer.
- Laminated MDF board. Nws yog them nrog PVC zaj duab xis, duplicating cov xim thiab cov qauv ntawm hom ntoo nrov. Tsis tas li ntawd, cov txheej no tuaj yeem ua rau matte lossis glossy tiav. Ua los ntawm cov khoom siv nocov khoom ntawm txee rooj tog rau chav nyob. Qhov ntau kuj yog siv los npaj chav dej, nrog rau kev sib ntxiv ntawm hydrophobic fillers uas tiv thaiv cov kua thiab chav.
- veneered vuas. Nyob rau hauv rooj plaub no, MDF yog pasted nrog nyias saws ntawm cov ntoo muaj nuj nqis. Ntawm cov minuses ntawm cov khoom siv no nco ntsoov tus nqi siab. Cov tsos ntawm cov khoom muaj qhov siab tshaj plaws zoo sib xws nrog cov ntoo veneer ntawm cov hom sib xws.
- YPlastic. Qhov no yog ib qho yooj yim tshaj plaws ntawm kev ua tiav ntawm cov khoom hauv nqe lus nug, nws yog feem ntau siv hauv kev lag luam rooj tog.
Qhov zoo tshaj plaws ntawm MDF boards
Cov hauv qab no yog cov npe ntawm cov chaw tsim khoom uas feem ntau tuaj yeem pom ntawm kev lag luam hauv tsev:
- SWISS KRONO GROUP. Lub tuam txhab Austrian pib nws txoj haujlwm thaum kawg ntawm lub xyoo pua 19th ua lub tshuab saw. Tam sim no lub tuam txhab no suav nrog ntau lub tuam txhab uas tshwj xeeb hauv kev tsim cov ntoo ua vaj huam sib luag. Hauv tebchaws Russia, lub npe hu ua Kronostar.
- P&M Kaindl. Lwm Austrian chaw tsim tshuaj paus ntawm MDF rooj tog boards. Hauv kev tsim cov khoom siv, cov cuab yeej siv high-tech thiab cov ntaub ntawv zoo tshaj plaws yog siv. Cov khoom raug xa tawm mus rau ntau lub tebchaws hauv ntiaj teb, xav tau thiab nthuav tawm ntau yam hloov pauv.
- KASTAMONU. Lub tuam txhab tau ua haujlwm txij li xyoo 1969, sawv cev los ntawm cov chaw haujlwm hauv Romania, Qaib ntxhw, Bosnia, Russia. Lub tuam txhab cov khoom lag luam suav nrog MDF boards nrog ntau yam txheej txheej, yog ib qho ntawm tsib analogues saum toj kawg nkaus hauv kev ua lag luam niaj hnub no.
- Sonae Industria. Lub tuam txhab Portuguese muaj ceg nyob rau hauv 12 lub teb chaws ntawm lub ntiaj teb no, thiab yog xyaum tsis inferior nyob rau hauv cov nqe lus ntawm kev muag khoom rau lwm yam zoo-paub cov neeg sib tw. Kev ua tau zoo tau lees paub los ntawm kev tswj ntau theem, nrog rau kev txhim kho txuas ntxiv ntawm cov thev naus laus zis siv.
Nyob rau hauv qeb ntawm MDF board manufacturers, cov npe hauv qab no yuav tsum paub qhov txawv:
- CJSC "Plitspichprom". Lub tuam txhab loj hauv tsev tshwj xeeb hauv kev tsim cov laminated thiab lwm yam MDF panels hauv 35 versions. Lub tuam txhab muaj cov chaw ua haujlwm sawv cev hauv ntau thaj tsam ntawm lub tebchaws. Kev tsim khoom siv Swiss, German thiab Italian thev naus laus zis nrog kev siv cov cuab yeej tsim nyog. Ob qho nyiaj txiag thiab cov khoom lag luam siab kawg muaj.
- "Zheshart plywood Hoobkas". Cov nroj tsuag tau ua haujlwm txij li xyoo 1946 thiab yog ib qho ntawm cov thawj coj hauv kev tsim cov khoom siv hauv tsev MDF. Cov khoom kuj tseem nquag xa tawm mus rau cov teb chaws nyob ze thiab deb txawv teb chaws.
- LLC "Master thiab K". Cov pab pawg tshwj xeeb ntawm cov tuam txhab tsis ntev los no tau ua tus chij ntawm kev tsim cov khoom hauv nqe lus nug hauv kev ua haujlwm hauv tsev. Cov khoom sau tau rov ua dua ib ntus nrog cov kab tshiab, cov uas txawm tias cov neeg siv khoom xav tau tshaj plaws yuav pom cov khoom lag luam nrog qhov yuav tsum tau ua thiab tsim.
- LLC "MDF cog". Qhov kev lag luam no yog cov nroj tsuag nrog lub voj voog ntau lawm. Kev tsim cov khoom lag luam pib nrog kev xaiv ntoo, nws sau thiab tso tawm cov khoom kawg. Ua tsaug rau kev tswj xyuas ib ntus, cov khoom siv tau zoo thiab ua tau raws li cov qauv thoob ntiaj teb.
cov lus qhia txog kev txhim kho
Kev txhim kho ntawm MDF boards yog ua los ntawm ib qho ntawm cov hauv qab no:
- Txhawm rau txhim kho cov khoom hauv nqe lus nug ntawm cov phab ntsa tsis sib xws nrog qhov sib txawv ntawm ntau dua 10 millimeters, siv cov qauv thav duab. Feem ntau nws yog ua los ntawm cov ntoo tuav nrog ib feem ntawm 2030 hli, uas tso cai rau koj los them rau qhov tsis zoo ntawm lub qab nthab.
- Ntawm qhov chaw tiaj tus, cov phiaj yog mounted siv cov kua nplaum tshwj xeeb lossis kua rau tes. Cov muaj pes tsawg leeg yog siv rau hauv zigzags los yog dots, tom qab uas daim ntawv yog muab tso rau ntawm phab ntsa. Nias nws rau ob peb feeb. Txoj haujlwm dav dav yog kho los ntawm tapping, tshuaj xyuas cov qib ntsug thiab kab rov tav. Cov pob qij txha raug kaw nrog putty.
- Cov khoom siv dej-resistant feem ntau yog muab tso rau hauv pem teb, uas muaj qhov tuab ntawm tsawg kawg yog 5 millimeters thiab qhov ntom ntom ntom ntawm 900 kg / cu. saib. Txwv tsis pub, txoj cai kev teeb tsa zoo ib yam rau cov lus pom zoo saum toj no.
