Ntau yam khoom siv hauv tsev ua kom yooj yim dua thiab tib lub sijhawm nyuaj rau kev xaiv cov neeg niaj hnub. Piv txwv li, peb feem ntau tsis tau hnov lo lus zoo li MDF. Tsis yog txhua tus paub tias nws yog dab tsi, thiab nws tuaj yeem nyuaj rau kev txiav txim siab. Qhov tseeb, nyob rau hauv cov ntawv luv no yog qhov nruab nrab-qhov ntom ntom fiberboard.
Nws thov nyob qhov twg?
Pib nrog, nws tsim nyog hais tias cov khoom tshuav nws cov tsos rau cov thev naus laus zis niaj hnub, raws li cov fiberboards tau tsim. Tsis muaj cov khoom siv hluavtaws hauv MDF; es tsis txhob siv lignin, uas twb muaj nyob rau hauv cov ntoo. Thiab qhov no qhia tias cov khoom siv xws li MDF yog ib puag ncig tus phooj ywg thiab kev nyab xeeb rau tib neeg kev noj qab haus huv, tias qhov no yog cov txheej txheem tshwj xeeb uas tuaj yeem siv rau veneer phab ntsa thiab lwm qhov chaw. Thaum lub sij hawm tsim khoom, cov khoom yuav dhau los ua:
- tiv taus kub thiab kub hloov;
- ruaj khov;
- waterproof.
Nws tseem yog ib qho tseem ceeb uas MDF yog tsim los ntawm cov cuab yeej siv high-tech, yog li nws qhov chaw tuaj yeem ua tau yooj yim. Tsuas yogTsis tas li ntawd, nws muaj peev xwm tso tawm cov khoom hauv txhua daim ntawv, txawm tias qhov txawv txav tshaj plaws. Staining, laminating, varnishing lossis enameling - MDF tuaj yeem raug rau tag nrho cov haujlwm no. Nws yog dab tsi thiab dab tsi yog qhov txawv ntawm cov khoom, peb xam nws tawm.
Phab ntsa cladding
Tiav ib chav tsev lossis ib lub tsev nyob hauv lub tebchaws nrog MDF panels rau phab ntsa tsis yog qhov txawv rau lub sijhawm ntev. Cov koob npe zoo li no tau piav qhia los ntawm qhov tseeb tias cov khoom siv tau yooj yim rau nruab, thiab yog li koj tuaj yeem nruab rau koj tus kheej. Kev xaiv loj ntawm cov xim thiab kev ntxhib los mos yuav tso cai rau koj xaiv tus qauv tsim rau txhua hom kev tsim sab hauv. Cov vaj huam sib luag tau txuas ncaj qha mus rau cov lus qhia, uas txuas nrog rau phab ntsa ua ntej.
Ua ntej txhim kho cov profiles, cov phab ntsa yuav tsum tau kho nrog cov sib xyaw tshwj xeeb - qhov no yuav tiv thaiv lawv los ntawm cov kab mob fungal, kab mob thiab ya raws. Cov profiles yuav tsum tau nruj nreem nyob ib sab ntawm ib leeg kom tsis muaj qhov sib txawv ntawm lawv. Txhawm rau ua kom cov txiaj ntsig tau zoo saib zoo nkauj thiab cov organic, koj yuav tsum siv ntau lub ces kaum thiab cov hniav zoo nkauj uas txuas nrog staples lossis kua nplaum. Tsis txhob hnov qab txog qhov cua ntawm phab ntsa thiab cov panels.
MDF ua li cas?
Kev tsim cov khoom siv yog ua nyob rau hauv ntau theem. Ua ntej, cov khoom siv raw yog sau (feem ntau nws yog ntoo zoo tib yam). Cov cav yog ntxuav ntawm cov tawv ntoo, txiav mus rau hauv me me chips, ib tug loj yog tau uas yuav tsum tau tshem ntawm cov khib nyiab, xuab zeb thiab raug rau steaming. Tom qab steaming, chips yog crushed rau hauvbinder resins ntxiv. Cov huab hwm coj raug xa mus rau lub tshuab ziab khaub ncaws, tom qab ntawd cov huab cua raug tshem tawm ntawm nws. Twb tau nyob rau hauv lub tshuab tsim, ntoo fiber (lub thiaj li hu ua fiber) yog tau. Nrog kev pab los ntawm lub tshuab tsim, qhov loj yog compressed rau hauv cov ntaub pua plag, nyob rau hauv lub zog ntawm ib tug xovxwm, cov seem cua yog nyem tawm ntawm nws.
theem tseem ceeb tshaj plaws ntawm kev tsim khoom yog MDF nias. Nws yog dab tsi? Qhov no yog txheej txheem uas cov ntaub pua plag ntoo tau dhau los ua qhov kawg nias, tom qab ntawd nws txiav thiab txias. Txhawm rau muab qhov zoo nkauj zoo nkauj, cov txiaj ntsig tau raug rau kev sib tsoo, lub thickness ntawm cov nplooj ntawv yog leveled, thiab qhov tsis xws luag raug tshem tawm. Yuav kom tau txais MDF boards, koj yuav tsum siv cov chips thev naus laus zis, urea-formaldehyde resin, ammonium chloride thiab paraffin. Cov khoom tuaj yeem tsuas yog khaws cia rau hauv daim ntawv ntim khoom thiab hauv chav uas cov av noo tsis siab tshaj 70%, thiab qhov kub siab tshaj plaws yog 25 ° C.
