I. Hom thiab hom sib txawv
* ** Fiber cement board:** Ib hom npe npe hais txog txhua qhov kev tsim vaj tsev ua los ntawm cov cement thiab fibers; nws tsis khi rau ib lub npe tshwj xeeb, thiab ntau lub tuam txhab tsim cov khoom zoo li no.
* ** Hardiflex:** Cov khoom lag luam los ntawm Australian tuam txhab James Hardie; nws sawv cev rau qhov tshwj xeeb siab - cov khoom kawg nyob rau hauv pawg fiber ntau cement board, thiab lub npe tshwj xeeb rau hom no.
II. Raw Material thiab Manufacturing txheej txheem sib txawv
* **Standard Fiber Cement Board:** Feem ntau siv cov txheej txheem atmospheric curing; raw khoom piv tsis nruj, kev sib koom ua qauv; qee cov khoom siv qis- tus nqi qis yuav suav nrog cov khoom siv rov ua dua tshiab; Qhov ceev sib txawv, feem ntau yog li ntawm 1.2 txog 1.6 g / cm³.
* **Hardiflex:** Siv qib siab - qib Portland cement raws li cov ntaub ntawv tseem ceeb ua ke nrog cov khoom muaj txiaj ntsig zoo ntawm - zoo cellulose fibers; tsim los siv lub hom phiaj - tshwj xeeb siab - cov txheej txheem ua kom muaj zog; Cov khoom tiav muaj qhov ruaj khov ntom ntom ntawm 1.7-1.9 g / cm³ thiab muaj cov qauv denser sab hauv crystalline.
III. Kev ua tau zoo Parameter sib txawv
* ** Flexural Strength: ** Txheem fiber ntau cement boards muaj lub zog flexural ntawm kwv yees li 25 MPa, qhov Hardiflex tshaj 35 MPa; nws qhov cuam tshuam tsis kam yog 1.4 npaug ntawm cov khoom lag luam.
* ** Dej Resistance:** Txheem fiber ntau cement boards muaj tus nqi nqus dej li ntawm 3-5% thiab nws yuav ua rau me ntsis o tom qab lub sij hawm immersion; Hardiflex muaj qhov nqus dej tsawg dua lossis sib npaug li 2% thiab qhia qhov tsis txaus ntseeg ntawm qhov hloov pauv tom qab 72 teev ntawm kev tso dej, ua rau nws tsim nyog rau ib puag ncig nrog ntev - lub sij hawm raug ya raws.
* ** Kev Pabcuam Lub Neej: ** Txheem fiber ntau cement boards muaj kev pabcuam sab nraum zoov ntawm kwv yees li 15-20 xyoo; Hardiflex tau dhau los ntawm huab cua tshwj xeeb- kev kho mob tiv thaiv, txuas ntxiv nws lub neej kev pabcuam sab nraum zoov mus rau ntau dua 25 xyoo, nrog kev khov zoo tshaj -thaw thiab kua qaub- alkali tsis kam.
IV. Product Specifications thiab Application Scenarios
* ** Txheem Fiber Cement Board: ** Txheem thicknesses li ntawm 6 mus rau 24 hli, feem ntau muaj nyob rau hauv universal ntau thiab tsawg; Feem ntau yog siv rau kev kho kom zoo nkauj yooj yim, cov txheej txheem faib phab ntsa, thiab lwm yam kev siv uas xav tau tsawg dua. Hardiflex: Muab cov khoom lag luam sib luag zoo li ntawm 3.5mm ultra-nyias mus rau 12mm ntxiv- tuab boards, haum rau cov ntawv thov xws li sab nrauv cladding, qab nthab, chav dej phab ntsa panels, thiab sab nraum zoov kab hlau rhuav phab ntsa; qee qhov tshwj xeeb sib txawv tuaj yeem ua haujlwm ncaj qha raws li cov txheej txheem thaub qab.
V. Nqe thiab kev ua raws li qhov sib txawv
Txheem Fiber Cement Board: Cov nqi lag luam sib txawv; cov khoom ntawm tib qhov ntev tsuas yog 50% -70% ntawm Hardiflex tus nqi, thiab cov khoom lag luam los ntawm qee cov tuam txhab me yuav tsis muaj asbestos- ntawv pov thawj pub dawb.
Hardiflex: Hais kom tus nqi siab dua - coj lub lag luam Philippine ua piv txwv, tus qauv 6 hli board muag rau kwv yees li 937 pesos. Tag nrho cov khoom lag luam tau sau meej meej tias asbestos-dawb thiab ua raws li cov qauv thoob ntiaj teb Class A ib puag ncig rau cov khoom siv hauv tsev.
