Fibreboard, qhov tseeb, yog cov txheej txheem ntoo tshwj xeeb. Qhov tshwm sim yog cov ntaub ntawv tiaj tus thiab muaj zog txaus.
Rau cov khoom siv hauv tsev no, yuav luag txhua cov ntoo fiber ntau yog siv, nrog rau ntau yam pov tseg uas tsis muaj kev cuam tshuam hauv kev ua ntoo. Lawv suav nrog shavings, bark, lumber trimmings, thiab lwm yam. Tag nrho cov ntaub ntawv raw khoom tau muab sib xyaw thiab pub rau hauv lub grinder, qhov chaw uas lawv hloov mus rau hauv homogeneous nplua crumb, haum rau kev hloov pauv ntxiv. Lub fiberboard nws tus kheej yog tau los ntawm kub nias npaj raw cov ntaub ntawv, thaum ntxiv tshwj xeeb additives yog ua tau. Yog li, muaj ob txoj hauv kev:
1. Qhuav. Thaum lub fiberboard tsuas yog tau los ntawm kev sib txuas ntoo fibers ua ke.
2. ntub. Nyob rau hauv rooj plaub no, lub crushed loj ntawm fibers yog tov nrog tshwj xeeb binders kom muaj zog thiab tsis kam mus rau dabtsi yog khoov. Feem ntau, cov khoom siv hluavtaws yog siv los ua cov khoom sib txuas.resin.
Fibreboard tau nthuav tawm hauv kev tsim kho kev lag luam hauv qhov dav tshaj plaws. Hauv qhov no, muaj kev faib tawm uas cov fiberboards sib txawv ntawm qhov loj me, qib ntawm rigidity thiab lub hom phiaj. Cia wb mus saib txhua pab pawg no.
Txij li cov fiberboard tuaj yeem siv tsis tau tsuas yog ua lub tsev thiab cov khoom tiav, tab sis kuj yog cov khoom siv insulating, ob hom boards txawv los ntawm lub hom phiaj, uas dais cov npe sib xws - xov thiab insulating fiberboard. Lawv qhov loj me yog txhais los ntawm cov qauv thiab tuaj yeem ntev txog 5.5 meters.
Lub rigidity ntawm fiberboard yog txiav txim los ntawm cov muaj pes tsawg leeg ntawm cov sib tov los ntawm uas nws yog ua. Yog li, muaj cov mos mos, ib nrab nyuaj, nyuaj thiab super-nyuaj boards.
Soft fiberboard yog dav siv rau lub suab thiab cua sov rwb thaiv tsev ntawm qab nthab, phab ntsa thiab qab nthab. Tsis tas li ntawd, nws yog siv los ua sheathing thiab leveling cov ntaub ntawv, raws li zoo raws li lub qhov rooj nplooj muab tub lim.
Semi-hard thiab tawv hom tau dav siv hauv cov txheej txheem ntawm kev ua tiav cov phab ntsa, lawv kuj ua cov khoom siv hauv ob sab phlu rau hauv pem teb. Hauv kev lag luam rooj tog, ntoo fiberboards yog siv los tsim cov txee, txee thiab tub rau khoom. Hauv kev lag luam tsheb, lawv tau siv los ua cov kab sab hauv ntawm cov neeg caij tsheb.
Super-hard fiberboard yog cov khoom siv hluav taws xob ntau tshaj plaws siv rau kev tsim cov vaj huam sib luag thiabvaj huam sib luag.
Qhov ntom ntawm cov khoom siv no kuj muaj qhov cuam tshuam loj rau nws cov yam ntxwv, thiab yog li ntawm thaj chaw siv. Txawm hais tias qhov kev thov kom zoo nkauj tuaj yeem ua kom txaus los ntawm txheej nrog cov yeeb yaj kiab tshwj xeeb thiab cov kev daws teeb meem, qhov tsis txaus sab hauv filling yuav tsis tiv taus. Qee lub sij hawm qhov no hem tsuas yog nrog kev sib yuav me me xwb, tab sis yog tias rooj plaub no nyuaj dua, ces qhov cub xaiv tsis raug tuaj yeem ua rau muaj teeb meem loj.
