1. Cov Qhov Rooj thiab Qhov Rai Yas Uas Muaj Cov Iav Fiber Uas Muaj Zog

Cov yam ntxwv ntawm lub zog tensile siab thiab lub teeb yuagCov khoom siv Iav Fiber Reinforced Yas (GFRP)Feem ntau them rau qhov tsis zoo ntawm cov qhov rooj thiab qhov rai yas hlau ib txwm muaj. Cov qhov rooj thiab qhov rai ua los ntawm GFRP tuaj yeem ua tau raws li ntau yam kev xav tau ntawm qhov rooj thiab qhov rai tsim thiab muab kev rwb thaiv tsev zoo. Nrog rau qhov kub thiab txias ntawm kev hloov pauv cua sov txog li 200 ℃, GFRP tswj tau qhov cua zoo heev thiab kev rwb thaiv tsev zoo hauv cov tsev, txawm tias nyob rau sab qaum teb uas muaj qhov sib txawv ntawm qhov kub thiab txias loj. Raws li cov qauv kev txuag hluav taws xob hauv tsev, qhov ntsuas thermal conductivity yog qhov tseem ceeb rau kev xaiv cov qhov rooj thiab qhov rai hauv kev tsim kho. Piv rau cov qhov rooj thiab qhov rai hlau aluminium alloy thiab yas uas twb muaj lawm hauv khw, cov qhov rooj thiab qhov rai GFRP zoo qhia txog cov txiaj ntsig zoo dua ntawm kev txuag hluav taws xob. Hauv kev tsim cov qhov rooj thiab qhov rai no, sab hauv ntawm lub thav duab feem ntau siv cov qauv hollow, ua kom cov khoom siv rwb thaiv tsev ua haujlwm tau zoo dua thiab nqus tau cov suab nrov, yog li txhim kho lub tsev lub suab rwb thaiv tsev.

2. Cov Khoom Siv Yas Uas Muaj Iav Fiber Ntau Ntxiv

Cov pob zeb ua vaj tse yog ib yam khoom siv dav hauv kev lag luam kev tsim kho, thiab cov formwork yog ib qho cuab yeej tseem ceeb rau kev ua kom cov pob zeb ua vaj tse raug nchuav raws li tau npaj tseg. Raws li cov ntaub ntawv tsis tiav, cov haujlwm tsim kho tam sim no xav tau 4-5 m³ ntawm cov formwork rau txhua 1 m³ ntawm cov pob zeb ua vaj tse. Cov formwork pob zeb ua vaj tse ib txwm yog ua los ntawm hlau thiab ntoo. Cov formwork hlau yog tawv thiab ntom, ua rau nws nyuaj rau txiav thaum lub sijhawm tsim kho, uas ua rau muaj kev ua haujlwm ntau ntxiv. Thaum cov formwork ntoo yooj yim txiav, nws cov kev siv rov qab yog qis, thiab qhov chaw ntawm cov pob zeb ua vaj tse tsim los ntawm kev siv nws feem ntau tsis sib xws.Cov khoom siv GFRP, ntawm qhov tod tes, muaj qhov chaw du, tsis hnyav, thiab tuaj yeem siv dua los ntawm kev sib txuas, muab tus nqi hloov pauv siab. Ntxiv mus, GFRP formwork khav theeb qhov system txhawb nqa yooj yim dua thiab ruaj khov dua, tshem tawm qhov xav tau rau cov clamps kem thiab cov thav ntawv txhawb nqa uas feem ntau xav tau los ntawm cov hlau lossis ntoo formwork. Bolts, hlau kaum sab xis, thiab cov hlua khi txiv neej txaus los muab kev kho kom ruaj khov rau GFRP formwork, txhim kho kev tsim kho zoo heev. Tsis tas li ntawd, GFRP formwork yooj yim ntxuav; txhua yam av qias neeg ntawm nws qhov chaw tuaj yeem raug tshem tawm thiab ntxuav ncaj qha, txuas ntxiv lub neej ua haujlwm ntawm formwork.

3. Cov Khoom Siv Iav Fiber Uas Muaj Zog Yas Rebar

Cov hlau rebar yog ib yam khoom siv uas siv ntau los txhim kho lub zog ntawm cov pob zeb. Txawm li cas los xij, cov hlau rebar ib txwm muaj teeb meem xeb heev; thaum raug rau cov chaw muaj xeb, cov pa roj xeb, cov khoom ntxiv, thiab cov av noo, nws tuaj yeem xeb tau zoo heev, ua rau cov pob zeb tawg dhau sijhawm thiab ua rau muaj kev phom sij ntawm kev tsim kho.GFRP rebar, qhov tod tes, yog cov khoom sib xyaw ua ke nrog polyester resin ua lub hauv paus thiab iav fibers ua cov khoom siv txhawb nqa, tsim los ntawm cov txheej txheem extrusion. Hais txog kev ua tau zoo, GFRP rebar ua rau muaj kev tiv thaiv corrosion zoo heev, rwb thaiv tsev, thiab lub zog tensile, ua rau muaj kev cuam tshuam thiab kev cuam tshuam ntawm cov pob zeb ua vaj tse. Nws tsis xeb hauv ntsev thiab alkali ib puag ncig. Nws daim ntawv thov hauv cov qauv tsim tshwj xeeb muaj kev cia siab dav.

4. Cov Kav Dej, Cov Kav Dej Khiav, thiab Cov Kav Dej HVAC

Kev tsim cov kav dej, cov kav dej ntws, thiab cov kav cua hauv kev tsim vaj tsev pab txhawb rau kev ua haujlwm ntawm lub tsev. Cov kav hlau ib txwm muaj feem yuav xeb yooj yim dhau sijhawm thiab nyuaj rau kev saib xyuas. Raws li cov khoom siv yeeb nkab uas loj hlob sai,GFRPMuaj lub zog siab thiab du nto. Kev xaiv GFRP rau cov kav dej cua, cov kav dej tso pa tawm, thiab cov kav dej kho dej khib nyiab hauv kev tsim dej, dej ntws, thiab kev tsim cua tuaj yeem ua rau cov kav dej siv tau ntev dua. Tsis tas li ntawd, nws txoj kev tsim qauv zoo heev ua rau cov neeg tsim qauv kho tau yooj yim kho qhov siab sab hauv thiab sab nraud ntawm cov kav dej raws li qhov xav tau ntawm kev tsim kho, ua kom cov kav dej muaj peev xwm nqa tau zoo dua.
