Kev tshuaj xyuas ntawm qhov kev hloov kho saum npoo ntawm cov basalt fibers
Raws li cov khoom siv fiber ntau inorganic, basalt fiber ntau lub zog zoo heev, Tshuaj tsis kam, thiab kub-kub stability tau coj mus rau ntau yam kev siv nyob rau hauv civil engineering, composite cov ntaub ntawv, thiab kev tiv thaiv ib puag ncig. Txawm li cas los xij, basalt fibers muaj qhov chaw du thiab tsis muaj cov pab pawg ua haujlwm, ua rau cov khoom siv tsis zoo nrog cov khoom siv matrix. Yog li ntawd, kev hloov kho saum npoo ntawm basalt fibers tuaj yeem txhim kho lawv cov kev sib txuas ntawm cov khoom sib txuas thiab txhim kho lawv daim ntawv thov hauv kev sib xyaw thiab kev tiv thaiv ib puag ncig. Cov hauv qab no yog kev tshawb fawb txog ntau yam kev hloov kho loj.
- Silane coupling tus neeg saib xyuas qhov chaw hloov kho
Silane coupling tus neeg sawv cev yog ib qho kev siv tshuaj kho qhov chaw uas txhim kho cov khoom sib txuas ntawm cov fibers thiab cov ntaub ntawv matrix los ntawm kev sib txuas tshuaj.
KH-550 Kev hloov kho
Txoj kev tshawb no qhia tau hais tias kev kho basalt fibers nrog ib tug silane coupling tus neeg saib xyuas KH-550 cov ntaub ntawv ruaj khov tshuaj bonds ntawm lub fiber nto thiab txhim kho cov interfacial bonding ntawm fiber thiab asphalt. Qhov tsim nyog concentration ntawm KH-550 yog 1.0%, thiab lub sijhawm kho yog 30 feeb. Tom qab hloov kho, qhov adhesion ntawm basalt fiber thiab asphalt tau txhim kho los ntawm qib 1. Cov roj nqus tau nce los ntawm 65.5%, uas txhim kho qhov adhesion nrog asphalt.
KH-570 Kev hloov kho
KH-570 hloov kho basalt fibers kom roughen lawv nto thiab ua kom cov ntsiab lus nquag ntawm fiber ntau. Nyob rau hauv cov khoom sib xyaw, nrog rau qhov nce ntawm qhov hloov kho fiber ntau ntev thiab qhov sib ntxiv, cov khoom siv sib xyaw ntawm cov khoom sib xyaw tau zoo tuaj.
- Kev hloov kho surfactant
CTAC kev hloov kho
Lub cev txheej ntawm basalt fibers nrog cationic surfactant cetyltrimethylammonium chloride (CTAC) txhim kho hydrophilicity thiab dispersibility ntawm fibers hauv dej. Txoj kev hloov kho no muaj qhov cuam tshuam loj rau microbial zaj duab xis adhesion: microbial adhesion lub zog tau nce ntau. Ua kom cov microbial txuas ntxiv ua kom yooj yim rau kev siv hauv kev kho dej khib nyiab.
- Organic hlau kua theem deposition hloov kho
Kev hloov kho ntawm basalt fibers los ntawm cov organic hlau ua kua theem tso tawm tuaj yeem txhim kho bio-adhesion peev xwm ntawm fiber ntau nto thiab ntxiv txhim kho nws daim ntawv thov hauv kev kho dej khib nyiab. Txoj kev hloov kho no tuaj yeem tsim cov hlau oxide ruaj khov rau ntawm qhov chaw ntawm fiber ntau los txhim kho nws cov adsorption thiab degradation ntawm cov pa phem.
- Txheej hloov kho los ntawm nano-silica
Nanosilica hais yog uniformly dispersed nyob rau hauv infiltrant los yog dispersion, thiab yuav ua tau basalt fiber txheej hloov kho: ntawm basalt fiber thiab epoxy resin, nanosilica hais ua tus choj lub luag hauj lwm, ho txhim kho lub interfacial compatibility ntawm ob. Tom qab kev hloov kho, qhov roughness ntawm basalt fiber ntau nce, thaj chaw tshwj xeeb nce ntxiv, thiab cov pab pawg ua haujlwm muaj pa oxygen nce. Txoj kev tshawb no qhia tau hais tias nrog kev siv cov nanosilica-hloov basalt fiber cab kuj: qhov tseeb npaum li cas ntawm microbial zaj duab xis ib gram ntawm fiber mounted nce los ntawm 21.39%. Kev tshem tawm cov pa phem tau zoo dua qub.
Xaus thiab Outlook
Kev ua haujlwm saum npoo, interfacial bonding zog thiab kev ua haujlwm ntawm basalt fibers tau txhim kho zoo los ntawm kev hloov kho deg sib txawv. Ntawm lawv:
- silane coupling tus neeg saib xyuas kev hloov kho yog tsim nyog rau kev txhim kho cov adhesion ntawm basalt fibers nrog cov ntaub ntawv matrix (xws li cement, asphalt, epoxy resin, thiab lwm yam).
- Kev hloov pauv surfactant thiab cov organic hlau tso tawm hloov pauv yog qhov tsim nyog rau thaj chaw tiv thaiv ib puag ncig, tshwj xeeb tshaj yog rau daim ntawv thov microbial hauv kev kho dej phwj.
- Nano-silica txheej hloov kho, nrog rau qhov zoo ntawm kev txhim kho cov khoom siv kho tshuab thiab kev ua haujlwm, muaj ntau yam kev cia siab hauv kev lag luam Cov khoom siv sib xyaw thiab kev tiv thaiv ib puag ncig.
Kev tshawb fawb yav tom ntej tuaj yeem ua kom zoo dua cov txheej txheem kev hloov kho tsis zoo thiab tshawb nrhiav cov txiaj ntsig ntawm kev hloov kho sib txawv kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
