Piv nrog rau qhov zoo tib yam uas tsis yog-alkali thiab nruab nrab-alkali iav fiber ntau, alkali-resistant iav fiber ntau muaj nws cov yam ntxwv zoo: alkali tsis kam, siab tensile zog, thiab muaj zog corrosion kuj nyob rau hauv cement thiab lwm yam muaj zog alkali xov xwm. Irreplaceable reinforcing khoom nyob rau hauv iav fiber reinforced cement khoom (GRC).
Alkali-resistant iav fiber ntau yog lub hauv paus khoom ntawm iav fiber ntau zog cement (GRC). Nrog rau qhov tob ntawm kev hloov kho phab ntsa thiab kev txhim kho kev lag luam, GRC tau siv dav hauv kev tsim vaj tsev sab hauv thiab sab nrauv phab ntsa, rwb thaiv tsev vaj huam sib luag, huab cua duct panels, vaj sketches, kos duab sculptures, civil engineering, thiab lwm yam. Qee cov khoom thiab cov khoom siv uas nyuaj lossis tsis sib piv rau cov pob zeb muaj zog tuaj yeem ua tau. Nws tuaj yeem siv rau hauv cov khoom siv tsis yog-load-bearing, theem nrab load-bearing, thiab semi-load-bearing lub tsev Cheebtsam, cov khoom siv kho kom zoo nkauj, chaw ua liaj ua teb thiab tsiaj txhu, thiab lwm yam.
Alkali-resistant iav fiber mesh daim ntaub yog ua los ntawm nruab nrab-alkali thiab alkali-dawb iav fiber mesh daim ntaub, uas yog ua tiav los ntawm acrylic copolymer kua nplaum. Cov ntaub mesh muaj lub zog siab, zoo heev alkali tsis kam, acid tsis kam, thiab zoo adhesion rau resin. Muaj zog, yooj yim soluble nyob rau hauv styrene, zoo heev nyob rau hauv nruj thiab positioning, feem ntau yog siv los ua cov ntaub ntawv ntxiv rau cov cement, yas, asphalt, ru tsev, thiab phab ntsa. Nws yog tsuas yog siv rau GRC pre-paving, smearing, los yog mechanized molding, tshwj xeeb tshaj yog haum rau kev tsim kho ntawm cov phab ntsa sab nrauv.
Alkali-resistant daim phiaj daim ntaub txheem
1. 14.5 feem pua rau 16.7 feem pua ntawm zirconia thiab 6 feem pua ntawm titanium dioxide yog nkag rau hauv cov iav muaj pes tsawg leeg, yaj ntawm qhov kub ntawm 1600 degree, kos rau hauv cov filaments txuas ntxiv los ntawm platinum, thiab twisted thiab twisted rau hauv cov iav fiber ntau. Thaum lub sij hawm tus txheej txheem, cov monofilaments yog coated nrog polymer dej-soluble epoxy resin thiab coupling tus neeg saib xyuas kom tau raws li affinity ntawm lub iav fiber mesh daim ntaub thiab cov alkali-resistant polymer thaum lub sij hawm tom qab ua.
2. Txhawm rau txhawm rau txhim kho kev nyab xeeb thiab ruaj khov ntawm cov alkali-resistant iav fiber mesh daim ntaub, nws yog coated nrog styrene-butadiene roj hmab thiab ntshiab acrylic emulsion tom qab warp knitting rau hauv ib lub leno zoo li, thiab nws yog glued nrog qhov kub thiab txias, tsis tu ncua ceev, thiab tas li nro tswj tshuab. Txaus (cov txheej txheem no yog cov txheej txheem alkali-resistant txheej tsim los ntawm BASF hauv Tebchaws Europe rau alkali-dawb iav fiber mesh daim ntaub) tuaj yeem tiv taus qhov yaig ntawm polymer mortar Ca (OH) 2 hydration lub sij hawm ntawm iav fiber ntau mesh daim ntaub thaum ntxov. Tom qab txheej txheej, lub zog tiv thaiv plam ntawm cov ntaub thaiv npog qhov taw qhia yog 3.5-4.5N.
3. Lub alkali tsis kam ntawm alkali-resistant iav fiber mesh daim ntaub yog tsis tsuas yog coated nrog ib tug alkali-resistant txheej, tab sis nws lub ntsiab alkali-resistant txoj kev yog tsim ib tug sib tov zaj duab xis ntawm zirconium thiab titanium ions nyob rau saum npoo ntawm fiber nws tus kheej. tiv thaiv kev yaig ntawm cov tshuaj alkaline. Nrog rau kev loj hlob ntawm lub sij hawm, cov tshuaj hauv lub xeev ntawm zirconium maj mam ua kom ruaj khov. Piv txwv li, alkali-resistant retention tus nqi ntawm alkali-resistant iav fiber mesh daim ntaub nyob rau hauv Table III yog ntau tshaj 85 feem pua, uas yog ntau dua li ntawm lwm cov iav fiber ntau alkali-resistant coated mesh ntaub, yog li peb kuj hu tau nws tej yam ntuj tso. alkali-resistant iav fiber mesh daim ntaub.
