Lub kiv puag ncig ntsiag to yog tshwm sim hauv kev lag luam khoom siv hauv tsev. Thawj tus neeg sib tw rau kev lag luam ntev - sawv "mus- mus rau" cov khoom siv hauv tsev - ntoo, phab ntsa qhuav, thiab cov qauv cement board - twb nyob ntawm no, thiab nws hu ua fiber ntau cement board. Raws li kev lag luam pioneers, peb tau tuaj yeem ua pov thawj qhov kev hloov pauv no thiab yuav ua li cas nws txhim kho kev lag luam kev daws teeb meem rau cov neeg siv khoom thoob ntiaj teb.
Kev txwv ntawm cov khoom siv niaj hnub
Cov kws tshaj lij hauv tsev siv ntau yam khoom siv los ua kom ntev, tab sis cov ntaub ntawv no tsis kav ntev, thiab feem ntau, tsim onspec. Ntoo, phab ntsa qhuav, thiab cement muaj qhov zoo thiab zoo sib xws. Ntoo rot, drywall deteriorates, thiab board cement tawg. Txhua thiab raws li ib tug collective, cov ntaub ntawv muaj ib tug txo lifeline. Kev tsim kho kev lag luam tau txuas ntxiv siv cov ntaub ntawv no, thiab yog li, raws li qhov kev poob qis tau pom los ntawm cov kws tshaj lij kev tsim kho, lawv kuj tau pom rau ntau txheej ntawm kev lag luam.
Nyob rau sab hnub tuaj Asia cov huab cua ntub, cov tsev ntoo feem ntau tsis kav ntev tshaj 15 xyoo. Nyob ib ncig ntawm Pacific Rim, qhov twg muaj av qeeg ntau, cov ntaub ntawv uas lawv siv feem ntau tsis muaj zog txaus, yog li lawv tsis muaj kev nyab xeeb. Thiab nyob rau hauv qhov chaw uas muaj hluav taws kub heev, cov ntaub ntawv tuaj yeem ntes hluav taws tau yooj yim, uas ua rau lub neej thiab lub tsev muaj kev pheej hmoo. Vim tag nrho cov no, muaj qhov xav tau loj rau cov khoom siv hauv tsev sib txawv.
Kev tawg ntawm Fiber Cement Board
Qhov tshwm sim ntawm fiber ntau cement pawg thawj coj saib tsis yog qhov xwm txheej, tab sis yog qhov tshwm sim ntawm cov ntaub ntawv tshawb fawb teb rau kev xav tau ntawm kev lag luam. Cov khoom siv sib xyaw no, muaj li ntawm cov cement, cellulose fibers, thiab cov pob zeb hauv av, ua tiav cov ntsiab lus ntawm qhov mob ntawm cov ntaub ntawv ib txwm muaj.
Nyob rau hauv cov nqe lus ntawm durability, fiber ntau cement boards deb tshaj ntoo nyob rau hauv lawv tsis kam mus ya raws, corrosion, thiab kab mob kab mob. Peb txoj haujlwm hauv tebchaws Australia tau pom tias cov phab ntsa sab nrauv siv fiber ntau cement boards pom tias tsis muaj kev puas tsuaj loj tom qab peb caug xyoo nyob rau hauv ib puag ncig siab - ntsev ntug dej hiav txwv, thaum cov ntoo zoo sib xws feem ntau yuav tsum tau kho loj hauv kaum xyoo.
Qhov nce hauv kev nyab xeeb yog qhov tshwj xeeb tshaj plaws. Fiber cement boards yuav tsis muaj hluav taws kub, muab sijhawm ntxiv rau lub sijhawm khiav. Lub tsev kho mob Chilean tau nce kev nyab xeeb ntawm hluav taws los ntawm ob theem txij li siv fiber ntau cement board faib.
Lub kiv puag ncig hauv kev teeb tsa thiab kev saib xyuas yog qhov tseem ceeb sib npaug. Lub teeb yuag tsim ntawm fiber ntau cement boards txo cov txheej txheem thauj khoom, thiab lawv qhov ntev ntev thiab qhov hnyav ruaj khov ua kom luv lub sijhawm teeb tsa. Ib tus neeg cog lus German tau tshaj tawm tias, piv rau cov khoom siv ib txwm muaj, fiber ntau cement boards txhim kho kev txhim kho kev ua haujlwm tau zoo los ntawm 40% thiab txo cov khib nyiab los ntawm 60%.
Ib txoj hauv kev tshiab los kov yeej cov kev sib tw
Kev nce qib ntawm cov khoom tshiab ntsib cov teeb meem, thiab fiber ntau cement boards tsis muaj qhov zam. Cov khoom thaum ntxov raug kev txom nyem los ntawm hnyav hnyav thiab brittleness. Peb tau hais txog cov teeb meem no los ntawm kev txhim kho fiber ntau thiab cov txheej txheem tsim khoom, ua rau muaj zog ntxiv thaum txo qhov hnyav los ntawm 30%.
Txhawm rau daws qhov kev txhawj xeeb ntawm ib puag ncig, peb tau tsim cov asbestos -dawb cov mis mos thiab siv cov cellulose txuas ntxiv dua tshiab. Kev ntsuam xyuas lub neej qhia tau hais tias peb cov fiber ntau cement boards muaj 45% qis dua tag nrho cov pa roj carbon hneev taw los ntawm kev tsim khoom mus pov tseg piv rau cov pob zeb ua vaj tse.
Tus nqi yog ib qho kev khuam siab. Los ntawm kev lag luam ntawm cov nplai thiab cov txheej txheem kev txhim kho, tus nqi ntawm fiber ntau cement boards tau txo los ntawm 35% nyob rau hauv kaum xyoo dhau los, muab lawv ib tug tseem ceeb kom zoo dua nyob rau hauv tag nrho lub neej voj voog kev suav nqi. Xav txog kev saib xyuas, hloov, thiab kev siv hluav taws xob, fiber ntau cement boards tuaj yeem txuag tau li 25% ntawm tag nrho cov nqi dhau lub tsev lub neej.
