Kev Sib Piv ntawm Particleboard Thiab MDF Hauv Cov Khoom Noj Mov Luam Ntawv

- Jun 11, 2018-

Lub rooj noj mov qhov rooj tog cov khoom siv tawg yog tawg los ntawm kev sib tw thiab kev ua los ntawm kev kub thiab kev kub siab. Qhov nruab nrab txheej ntawm cov rooj tog tsev tog cov khoom noj khoom siv yog cov ntoo ntoo chips, thiab ob sab yog cov khoom ntoo zoo nkauj thiab nias rau hauv cov laug cam. Ntu txheej yog txheej fwj, lub homogeneous particle board yog qhov zoo tshaj plaws, cov khoom vaj khoom tsev muaj cov qauv ntawm cov qauv hauv molecular, thiab lub zog khoov siab siab. Chipboard muaj lub zoo dua ntawm tsis yooj yim deforming thiab tuav tes. Lub disadvantage ntawm particleboard yog tias nws tsis yooj yim los ua bending kev kho los yog nkhaus seem ua, thiab nws yuav tsum ua siab machinery.


Cov rooj tog tsev noj mov MDF yog ua raws li cov ntoo ntoo ua cov khoom siv raw khoom, ua los ntawm kub sib tsoo, paving, kub nias thiab lwm cov txheej txheem. Cov nta yog cov qauv sab hauv, kev ua haujlwm zoo, yooj yim rau kos thiab ua ntau hom duab, cov duab thiab cov khoom. MDF (450-780) feem ntau muaj qhov zoo ntiag tug, ces thaum nto yuav tsum tau thim thiab milling, thiab cov nplaum yuav tsum tau muab pov tseg yog ib qho khoom siv ziab (xws li ib daim npav), siv MDF los xyuas kom meej tias cov yeeb yaj kiab tau them . tiaj tus. Nws yog feem ntau siv los txhim kho cov ntoo hauv tsev, qhov rooj thiab lwm yam.


Hnyuv ntxhib: MDF yog ntoo hmoov nias thiab tsim, qhov chaw npoo npau yog qhov zoo, li ntawd thaum lub qhov chaw xav tau kev tu ncua thiab milling, moulding, thiab cov nplais ntsej muag yog qhov muag zoo nkauj (xws li lub hnab yas paj taub hau), feem ntau siv qhov nruab nrab Board kom paub meej tias qhov saum npoo tom qab zaj duab xis yog tiaj. Txawm li cas los xij, vim tias cov ntaub ntawv raw tag nrho cov hmoov nplej zoo heev, los ntawm kev xav ntawm cov dej noo, yog hais tias cov khoom sib tsoo particle soaked hauv dej, vim cov ntoo muaj fiber ntau ntev hauv cov khoom qub, cov qauv ntawm cov ntoo yog khaws cia ntau, ces tus particle board yuav tsis nthuav thaum nws nthuav mus rau ib qhov twg. (8% -10%). Yog li ntawd, qhov kev kawm ntawm kev ya-pov thawj tau hais tias pawg neeg particle yog superior ntawm lub rooj sib tham ceev. Yog li no, European thiab American rooj tog tsev txee tuam txhab uas muag tsis muaj kev tsim nyog siv cov ntawv ntim rau lub thawv ntawv.


Kev tiv thaiv ib puag ncig: Tsis ntev los no, yuav luag tag nrho cov rooj tog tsev noj mov thiab chav ua noj hauv Tebchaws Europe thiab Tebchaws Asmeskas siv cov khoom tawg. Piv txwv li, lub teb chaws Yelemees prestigious BERLONIROSSI, S-BEKA, thiab lwm yam siv cov particleboard. Muaj ntau lub tuam txhab loj siv cov khoom siv (cov peev tshaj 200 plhom yuan). Nws tseem tuaj yeem tsim cov khoom sib txuas nrog cov qauv ntawm cov qauv hauv molecular thiab siab khoov siab. Feem ntau, yog hais tias qhov chaw dai kom zoo nkauj yog tuaj ntawm lub teb chaws Yelemees, lawv feem ntau yog tsim los ntawm cov zeeg loj thiab siv cov rooj tog zaum kawg. Cov neeg lag luam thiab cov neeg muag khoom cuam tshuam ntau dua rau kev ua lag luam, yog li muaj teeb meem tsawg dua. Tam sim no, muaj qee qhov chaw me me uas muaj peev xwm tsim tau ib co kab uas muaj ntau lub rooj tsav khoom ua ke thiab ntoo pawg. Vim tias cov khoom siv thim rov qab thiab cov txheej txheem ntau lawm, cov laug cam uas ua rau cov neeg tsis muaj peev xwm, muaj peev xwm ua kom tsis muaj zog thiab ua kom lub cev muaj zog, thiab cov rooj tog zaum tau zoo. Nws yog ib qho yooj yim los ua kom qis qis, ua kom qis thiab ces zawm lub zog, thiab nthuav sai sai tom qab dej. Thiab cov ntsiab lus formaldehyde yog siab heev thiab ntau tshaj li lub teb chaws tus qauv ntawm ob peb zaug. Nws yog teeb meem rau tib neeg lub cev. Nws yog qhov zoo ntawm hom ntawm pawg thawj coj uas tau muaj lub npe ntawm lub koob npe nrov ntawm particleboard thiab tau coj tau txais kev pab kom yuam kev ntseeg tias cov thawj coj ntawm pawg thawj coj tsis zoo. Lub keeb kwm ntawm MDF daim hlau tsis ntev heev, thiab cov ntoo thawj yeej raug neeg phem, yog li yuav tsum tau siv phaj xwb. Yog li, cov ntawv ntim cov pa tawm tuaj, tab sis vim muaj ntau cov kua nplaum uas siv rau cov txheej txheem ntawm cov kab sib tsoo, yog tias qhov zoo ntawm cov kev ua ub no tsis dhau, los yog qhov tsis ruaj khov yuav ua rau ntau formaldehyde nyob rau hauv cov ntawv ceev, tsuas yog ntes tau formaldehyde emission thiab ua kom muaj zog thiab ceev. Lub Rooj Tswjhwm Saibxyuas muab faib ua E1 thiab qib E2 raws li cov formaldehyde emission, thiab formaldehyde emission tshaj 30mg / 100g. Feem ntau, feem ntau ntawm MDFs ntawm lub tuam qib siab yog tsim nyog. Feem ntau ntawm MDFs hauv kev ua lag luam yog E2 qib, thiab qib E1 tsawg dua. Zuag qhia tag nrho, cov khoom seem particle tswj qhov kev tiv thaiv coefficient ntau ntau tshaj qhov kev sib tham ntawm cov koom haum. Thiab ceev ntsa boards feem ntau yog siv rau qhov rooj panels los yog styling, thiab tsis tshua siv ua khoom.


Grip nailing: rooj tog tsev noj mov MDF yog muaj hmoov, yooj yim rau kev nthuav dav dej. Yog li ntawd, nws tsis raug siv raws li lub txee, thiab vim nws cov pluag ntsia hlau-ntaus ntawv, nyob rau hauv qhov xwm txheej yooj yim, lub khob ntom ntsa pov rau cov nplaim thiab rub tawm. Li no, nws tsis tuaj yeem rov qab tsib zaug, thiab nws tsis siv ntxiv lawm. Txawm li cas los xij, cov khoom siv sib xyaw ua yog tsim ntawm ntoo chips, nias rau hauv lub phaj, muaj cov yam ntxwv ntawm cov ntoo, muaj ib txhia ntsia thawv tuav, raws li ib txwm muaj peev xwm rov ua dua txog 10 zaug.


Compression Resistance: Cov txheej txheem nruab nrab ntawm cov rooj tog tsev noj mov particleboard yog ua los ntawm cov ntoo ntev, nrog cov nplaum fibers rau ob sab thiab nias rau hauv daim hlau. Lub cev molecular yog nruj thiab qhov siab zog yog siab. Peb tau ua tib yam kev xyaum ua thiab siv tib lub thickness thiab ntom ntawm MDF thiab pawg neeg tswj xyuas nrog qhov hnyav ntawm 50 kg. Tom qab 2 lub hlis, MDF loj heev deformed thiab cov khoom lag luam me ntsis deformed. Vim nws txoj kev siab tawv, muaj zog khov kho muaj peev xwm, thiab muaj lub peev xwm zoo ntawm qhov kev loj hlob, particleboard yog tsim rau kev sib txuas ntawm cov txee thiab laminates. Tam sim no, txhua qhov chaw txee rau cov khoom siv hauv Tebchaws Europe thiab tebchaws Asmesliskas siv cov khoom ua haujlwm, thiab cov khoom ntiag tug kuj tseem siv cov khoom sib xws li lub txee. . Cov ntawv nplaum yog tsim rau qhov rooj ntawm lub qhov rooj vim nws lub cev ceev nrooj. Qee lub npe ua cov khoom ntim puv ntawm cov txawb khoom sib txig lossis lub rooj sib koom ceev. Qhov no yog qhov tsis muaj dab tsi, thiab nws yooj yim yog deformed yog tias nws siv sij hawm ntev.
