Fiber ntau board yog dab tsi?
Nov 22, 2019
Fiberboard yog cov ntoo ua raws li cov ntoo ua los ntawm lignocellulosic fibers interwoven rau hauv cov duab thiab siv nws cov lus qhia qhov tseeb cov nplaum. Cov nplaum thiab / lossis cov khoom siv quav ntxiv yuav siv tau thaum lub sijhawm txheej txheem tsim khoom.
Fiberboard, tseem hu ua ceev board, yog ntoo fiber los yog lwm yam zaub fiber ntau li raw cov ntaub ntawv, urea formaldehyde cob lossis lwm cov khoom siv nplaum ua los ntawm cov ntoo ua pawg thawj coj saib. Fibreboard muaj qhov zoo ntawm cov khoom siv tsis yooj yim, lub zog me sib txawv thiab tsis yooj yim rau kev tawg. Kev tsim 1 cubic meter fiberboard xav tau lub ntoo ntawm 2.5 ~ 3 cubic meter txog, tuaj yeem hloov 3 cubic metre hloov ntoo lossis 5 lub cav sau lo lus teb. Kev tsim kho cov ntoo fiberboard yog txoj hauv kev zoo ntawm kev siv cov khoom siv ntoo.
Qhov tsis zoo ntawm fibreboard yog tias lub nraub qaum tau rov ua kom tiav, ua rau thaj chaw tsis sib luag ntawm ob sab ntawm lub rooj tsavxwm, vim qhov sib txawv ntawm lub zog quab yuam tom qab nqus noo thiab ua rau lub rooj ua haujlwm warped deformation; Phaj nyuaj saum npoo tawv, ntsia hlau tsis zoo, tsis muaj dej tsis kam. Cov fiberboard qhuav zam qee qhov kev tsis zoo tab sis raug nqi ntau dua.
Tuam Tshoj cov duab hluav taws xob ntau lawm tau pib xyoo 1970, tsim tawm xyoo 1980s, thiab pib tawm xyoo 1990. Txij li thaum pib ntawm lub xyoo pua 21st, qhov kev tsim cov ntoo fiberboard tau nce ntau, ntau tshaj 20 lab m3 rau thawj zaug xyoo 2005 rau 49.54 lab m3 hauv xyoo 2011. Cov khoom tso tawm ntawm fibreboard hauv henan xeev tau txog 6.98 lab cubic meters hauv xyoo 2011, nce 44.87 feem pua los ntawm Xyoo 2010, ntsuas txog 14.09 feem pua ntawm tag nrho lub teb chaws. Nws tau ua raws li guangxi, jiangsu thiab shandong, suav 12.84 feem pua, 9.76 feem pua thiab 8.56 feem pua, feem. Txij Lub Ib Hlis Ntuj txog Lub Xya Hli, 2012, kev tsim cov xov paj fiber ntau hauv Suav teb nce mus txog 29805100.39 square metres, nce ntawm 11.3% piv nrog rau tib lub sijhawm hauv xyoo 2011.
