Ua ntej, nws ua li cas?
Cov khoom siv sib xyaw hu ua fiber ntau cement board yog tsim los ntawm tsis yog - ntxiv fibers, cement, units ntawm nplua (silica) xuab zeb, thiab ntau yam additives. Fiber cement boards yog ntub dej -pulped, zoo li tus siv pwm, thiab kho nyob rau hauv siab siab los tsim cov khoom kawg.Koj tuaj yeem pom cov fiber ntau cement board ua ib daim ntawv me me ntawm cov pob zeb ua kom muaj zog- nyob rau hauv cov fibers ua tau zoo li lub cev pob txha rau ntxiv toughness thiab cov cement / xuab zeb ua lub cev muab cov fiber ntau cement board nrog ntxiv zog thiab hardness.
Cia peb pib nrog nws "core zog": flexural zog
Ntau tus neeg xav tias cov cement- cov khoom raws li nkig thiab ua rau tawg. Txawm li cas los xij, fiber ntau cement board yog qhov sib txawv heev. Nws lub zog flexural-tsuas yog, nws tuaj yeem khoov ntau npaum li cas ua ntej tawg - feem ntau ncav cuag 15-25 MPa lossis siab dua.
Qhov no txhais li cas? Koj tuaj yeem yooj yim tawg lub plasterboard tsis tu ncua nrog me ntsis khoov, tab sis fiber ntau cement board ntawm tib lub thickness yuav tsum muaj ntau lub zog thiab deformation tseem ceeb ua ntej nws tawg. Qhov kev nyuaj no tso cai rau nws tiv taus cua siab, kev txav me me, thiab txawm tias hauv av qeeg -cov cheeb tsam, nws tuaj yeem "tshaj rigidity nrog yooj" yam tsis muaj cracking.
Stability: cuam tshuam tsis kam
Xav txog ib qho cuab yeej tsoo lub phab ntsa thaum lub sij hawm tsim kho, los yog lawg tsoo rau sab nrauv. Hauv cov xwm txheej no, qhov zoo ntawm fiber ntau cement board ua kom pom tseeb. Tsis zoo li cov vuas luaj ceramic, uas tuaj yeem nti tau yooj yim, lossis qee cov boards nyias uas tuaj yeem raug punctured, fiber ntau cement board tau txais txiaj ntsig los ntawm nws cov fiber ntau - cov qauv siv zog, uas cuam tshuam rau kev cuam tshuam cov quab yuam.
Kev puas tsuaj hauv cheeb tsam yog ib qho ntawm cov khoom siv no thaum muaj kev cuam tshuam loj; xws li kev puas tsuaj hauv cheeb tsam yuav tshwm sim ntau dua li qhov tawg loj, thiab qhov no yog qhov tseem ceeb los xyuas kom muaj kev nyab xeeb nyob rau lub sijhawm ntev, thiab pab kom txo nqi rau kev kho.
Kev tiv thaiv ib puag ncig tuaj yeem ntsuas tau los ntawm ntau yam sib txawv, suav nrog khov -thaw thiab huab cua tiv taus.
Txias-thaw tsis kam muaj qhov tseem ceeb dua rau cov ntaub ntawv uas tsis yog- cov khoom tsim khoom (xws li sab nraud). Tsis tas li ntawd, tag nrho cov ntaub ntawv yuav tsum muaj peev xwm tiv taus qhov txias txias thiab thawing, tshwj xeeb tshaj yog nyob rau hauv ib feem vim tias qhov kub thiab txias tuaj yeem hloov pauv mus rau ib hnub & hmo ntuj.
Nrog rau siab -siab kho, fiber ntau- cement board muaj qhov porosity qis dua li cov cement board, txhais tau tias nws tsis nqus dej sai li sai tau. Qhov kub qis (los ntawm -20℃mus rau 30℃Celsius) yuav tsis ua rau cov kab nrib pleb tsim los yog ua puas lub fiber ntau cement board raws li yuav tshwm sim nrog cov masonry zoo tib yam. Cov kev ntsuam xyuas tau pom tias qhov poob qis tsawg heev tom qab tau txais ntau lub voj voog khov / thaw.
Tsis tas li ntawd, vim tias fiber ntau cement board yog tsim los ntawm cov ntaub ntawv uas tsis yog organic, nws tsis degrade los ntawm dej (xws li los nag) los yog UV teeb (xws li tshav ntuj). Tom qab 20 mus rau 30 xyoo ntawm kev raug rau ob lub ntsiab lus ntawm dej thiab UV teeb, lub cev yam ntxwv ntawm fiber ntau cement board yuav nyob twj ywm ib yam li lawv tau ua thaum xub thawj tsim.
Kev nyab xeeb kev ua haujlwm: hluav taws kub thiab noo noo tsis kam
Asbestos-dawb fiber ntau cement siding yog Class A uas tsis yog- cov khoom siv hluav taws xob. Fiber cement siding yuav tsis combustion los yog tsim cov pa phem thaum raug kub heev; nws qhov tseem ceeb tsuas yog hloov cov cua sov. Qhov no ua rau fiber ntau cement siding qhov kev tiv thaiv hluav taws zoo rau txhua qhov haujlwm fiber ntau cement siding uas yuav tsum tau muaj kev kub ntxhov siab.
Ntxiv rau qhov muaj peev xwm tiv taus kev puas tsuaj, fiber ntau cement siding kuj zoo heev ntawm kev tiv thaiv ya raws kev puas tsuaj. Fiber cement siding yuav tsis tso cai rau mildew loj hlob los yog shrinkage los ntawm cov dej noo ntau dhau, thiab fiber ntau cement siding yuav nyob ruaj nrees txawm tias nyob rau hauv high humidity tej yam kev mob nyob rau hauv cov cheeb tsam uas muaj ib tug siab noo noo cov ntsiab lus, xws li chav dej thiab hauv qab daus.
