Fiber-cov ntaub ntawv siv cov cement sib xyaw siv cov cement silicate ua cov matrix, ua ke nrog alkali-cov iav fiber ntau, cog fiber ntau, los yog siab -cov khoom siv hluavtaws ua cov khoom siv ntxiv. Nws yog tsim los ntawm cov txheej txheem meej xws li pulping, nqus dej kom huv, siab-siab molding, siab-kub kub curing, thiab kev sib txuas sib txuas. Nws feem ntau siv cov qauv sandwich ntawm "fiber cement vaj huam sib luag + cov khoom siv hluav taws xob rwb thaiv tsev," ua tiav cov txheej txheem sib xyaw, hluav taws kub, thermal rwb thaiv tsev, thiab suab rwb thaiv tsev ua haujlwm. Cov khoom lag luam nruj me ntsis ua raws li lub teb chaws thiab cov qauv kev lag luam xws li JC/T 412.1-2018 "Asbestos-dawb Fiber Cement Board" thiab JG/T 396-2012 "Tsis yog-load-Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob." Nws yog asbestos tag nrho-dawb, formaldehyde-dawb, thiab VOC-dawb, thiab nws cov xov tooj cua ua tau raws li qhov yuav tsum tau muaj ntawm GB 6566, ua rau nws muaj kev nyab xeeb rau kev siv hauv tsev kho mob, tsev kawm ntawv, chaw nyob, chaw huv, thiab lwm qhov chaw uas muaj kev tiv thaiv ib puag ncig nruj.
Hais txog kev ua tau zoo, cov khoom no muaj ntau yam zoo. Hais txog kev nyab xeeb hluav taws, pawg thawj coj ua tiav Chav Kawm A uas tsis yog -combustible combustion kev ua tau zoo nrog qhov hluav taws kub tsis pub dhau 0.5-2 teev. Nws ua tsis muaj pa luam yeeb lossis cov pa phem thiab tsis ntws los ntawm qhov kub thiab txias, muab kev tiv thaiv hluav taws zoo rau siab - cov tsev nce siab, cov chaw pej xeem, cov chaw tsim khoom, cov kav dej, qhov taub, thiab lwm yam kev siv zoo sib xws. It exhibits significant lightweight and high-strength characteristics, with low surface density and low structural load, making it suitable for high-rise construction and renovation of old residential areas. Nws lub zog flexural nce mus txog 15-30 MPa, ua rau nws cuam tshuam -tiv taus, tawg{13}} tiv taus, thiab cua{14}} siab tiv taus. Nws tsis yooj yim deformed, bulged, los yog tawg nyob rau lub sij hawm ntev - siv. Tsis tas li ntawd, lub rooj tsavxwm tsis muaj dej tsis zoo, noo noo{18}} pov thawj, thiab pwm pwm- pov thawj, nrog rau qhov nqus dej tsawg thiab qis qis qis. Nws ruaj khov thiab ruaj khov nyob rau hauv chav ua noj, chav dej, hauv qab daus, thiab siab - qhov chaw nyob ntawm ntug dej hiav txwv, tiv thaiv pwm kev loj hlob thiab rot, nrog rau lub neej kev pab ntau tshaj 50 xyoo.
Tsis tas li ntawd, fiber ntau-cov cement sib xyaw ua ke sib xyaw ua ke thermal rwb thaiv tsev thiab lub zog txuag nrog lub suab rwb thaiv tsev zoo. Nws cov qauv sib xyaw muaj cov thermal conductivity tsawg, txo cov kev siv hluav taws xob hauv tsev; Lub suab rwb thaiv tsev hnyav tuaj yeem ncav cuag tshaj 45dB, txhim kho qhov kev ceev ntiag tug. Cov txheej txheem kev tsim kho siv cov txheej txheem qhuav, tso cai rau kev txiav, drilling, nailing, thiab gluing, shortening lub sij hawm tsim kho thiab txo cov nqi zog, ua raws li txoj kev loj hlob ntawm kev tsim kho vaj tsev zoo. Cov khoom tshwj xeeb yog cov dav, nrog cov qauv loj ntawm 1220mm × 2440mm thiab thicknesses xws li 4mm txog 30mm. Composite sandwich vaj huam sib luag thicknesses tuaj yeem ncav cuag 50-200mm, nrog qhov ntom ntawm 1.3-2.0g / cm³. Nws kuj tseem muaj ntau yam kev ua tiav, suav nrog lub rooj tsav xwm dawb, sanded, fluorocarbon txau, xim pob zeb, ntoo lis, thiab pob zeb lis, ua tau raws li ntau hom kev tsim thiab kho kom zoo nkauj.
Tam sim no, fiber ntau -cov cement sib xyaw ua ke tau dav siv hauv kev tsim cov phab ntsa sab hauv, sab nrauv phab ntsa cladding, ntaub phab ntsa hauv ob sab phlu, kev thermal rwb thaiv tsev sab nrauv phab ntsa, fireproof ceilings, ru tsev linings, thiab qab nthab pem teb slabs, ua tau zoo heev nyob rau hauv lub chaw ua hauj lwm vaj tse, tsev so, khw muag khoom substrate, factories, cov ntaub ntawv nyob rau hauv ib ntus. Piv nrog rau cov tsoos gypsum board, masonry phab ntsa, thiab calcium silicate board, cov khoom no muaj qhov zoo ntawm kev nyab xeeb, durability, kev tsim kho, thiab tag nrho lub neej - voj voog tus nqi, ua raws li ntsuab thiab qis - cov pa roj carbon txoj cai cov lus qhia thaum txhim kho qhov zoo thiab kev ua haujlwm ntawm engineering engineering.
Raws li ib qho tseem ceeb ntawm cov khoom siv hauv tsev ntsuab, fiber ntau -cov cement sib xyaw ua ke tsav cov khoom hloov kho dua tshiab los ntawm kev siv thev naus laus zis tshiab thiab txhawb nqa kev tsim vaj tsev nrog kev ua tau zoo. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm cov qauv kev lag luam thiab kev ua kom zoo ntawm cov txheej txheem tsim khoom, qhov siab - kev ua tau zoo ntawm pawg thawj coj saib yuav nthuav dav nws daim ntawv thov ciam teb, muab cov khoom muaj zog txhawb rau siab - kev tsim kho hauv nroog thiab nyob deb nroog thiab kev txhim kho txuas ntxiv ntawm kev nyob ib puag ncig.
