Kev tshuaj xyuas cov kev tshawb fawb txog kev hloov pauv ntawm cov fibers basalt
Raws li cov khoom siv fiber inorganic ua tau zoo, basalt fiber cov khoom siv kho tshuab zoo heev, Tshuaj lom neeg kev tsis kam, thiab kev ruaj khov kub siab tau ua rau muaj ntau yam kev siv hauv kev tsim kho vaj tse, cov ntaub ntawv sib xyaw, thiab kev tiv thaiv ib puag ncig. Txawm li cas los xij, cov fibers basalt muaj cov nplaim du thiab tsis muaj cov pab pawg ua haujlwm nquag, ua rau cov khoom sib txuas tsis zoo nrog cov ntaub ntawv matrix. Yog li ntawd, kev hloov kho ntawm cov fibers basalt tuaj yeem txhim kho lawv cov khoom sib txuas thiab txhim kho lawv daim ntawv thov hauv cov khoom sib xyaw thiab kev tiv thaiv ib puag ncig. Cov hauv qab no yog kev tshawb fawb txog ntau txoj kev hloov kho loj.
- Kev hloov kho qhov chaw ntawm tus neeg sawv cev silane coupling
Silane coupling agent yog ib qho tshuaj kho qhov chaw uas feem ntau siv los txhim kho cov khoom sib txuas ntawm cov fibers thiab matrix los ntawm kev sib txuas tshuaj lom neeg.
Kev Hloov Kho KH-550
Cov kev tshawb fawb qhia tau hais tias kev kho cov fibers basalt nrog cov tshuaj silane coupling agent KH-550 tsim cov tshuaj sib txuas ruaj khov ntawm qhov chaw fiber thiab txhim kho kev sib txuas ntawm cov fiber thiab asphalt. Qhov concentration tsim nyog ntawm KH-550 yog 1.0%, thiab lub sijhawm kho yog 30 feeb. Tom qab hloov kho, qhov kev sib txuas ntawm cov fiber basalt thiab asphalt tau txhim kho los ntawm 1 qib. Tus nqi nqus roj tau nce 65.5%, uas ua rau muaj kev sib txuas nrog asphalt zoo dua.
KH-570 Kev Hloov Kho
KH-570 hloov kho cov fibers basalt kom ua rau lawv qhov chaw ntxhib thiab ua rau cov ntsiab lus nquag ntawm qhov chaw fiber ntau ntxiv. Hauv cov khoom siv sib xyaw, nrog rau kev nce ntawm qhov ntev ntawm cov fiber hloov kho thiab qhov ntau ntxiv, cov khoom siv kho tshuab ntawm cov khoom siv sib xyaw tau zoo dua.
- Kev hloov kho surfactant
Kev hloov kho CTAC
Kev siv cov tshuaj cationic surfactant cetyltrimethylammonium chloride (CTAC) los pleev cov fibers basalt kom zoo dua qub thiab ua rau cov fibers hauv dej tsis sib xyaw. Txoj kev hloov kho no muaj feem cuam tshuam rau kev nplaum ntawm cov zaj duab xis microbial: lub zog nplaum ntawm cov microbial nce ntxiv. Kev nce ntxiv ntawm cov microbial attachment ua rau kev siv hauv kev kho dej khib nyiab yooj yim dua.
- Kev hloov pauv ntawm cov kua hlau organic
Kev hloov kho ntawm cov fibers basalt los ntawm cov organic iron kua theem deposition tuaj yeem txhim kho lub peev xwm bio-adhesion ntawm qhov chaw fiber thiab txhim kho nws daim ntawv thov hauv kev kho dej khib nyiab. Txoj kev hloov kho no tuaj yeem tsim cov hlau oxide txheej ruaj khov rau ntawm qhov chaw ntawm cov fiber kom txhim kho nws cov adsorption thiab kev puas tsuaj ntawm cov pa phem.
- Kev hloov kho txheej los ntawm nano-silica
Cov khoom me me Nanosilica tau sib xyaw ua ke hauv qhov nkag mus lossis kev sib kis, thiab tuaj yeem hloov kho cov txheej txheem fiber basalt: ntawm cov fiber basalt thiab epoxy resin, cov khoom me me nanosilica ua lub luag haujlwm txuas, txhim kho qhov sib xws ntawm ob qho tib si. Tom qab hloov kho, qhov roughness ntawm cov fiber basalt nce ntxiv, thaj chaw tshwj xeeb nce ntxiv, thiab cov pab pawg ua haujlwm uas muaj oxygen nce ntxiv. Kev tshawb fawb qhia tau tias nrog kev siv cov khoom siv fiber basalt uas tau hloov kho nanosilica: qhov tseeb ntawm cov zaj duab xis microbial ib gram ntawm cov fiber mounted nce ntxiv 21.39%. Kev tshem tawm cov pa phem tau zoo dua.
Xaus Lus thiab Outlook
Cov dej num ntawm qhov chaw, cov khoom sib txuas ntawm cov interfacial thiab kev ua haujlwm ntawm cov fibers basalt tau zoo dua los ntawm ntau txoj kev hloov kho ntawm qhov chaw. Ntawm lawv:
- Kev hloov kho tus neeg sawv cev silane coupling yog qhov tsim nyog dua rau kev txhim kho qhov adhesion ntawm basalt fibers nrog cov ntaub ntawv matrix (piv txwv li cement, asphalt, epoxy resin, thiab lwm yam).
- Kev hloov kho surfactant thiab kev hloov kho cov hlau organic deposition yog qhov tsim nyog dua rau thaj chaw tiv thaiv ib puag ncig, tshwj xeeb tshaj yog rau kev siv cov kab mob microbial hauv kev kho dej phwj tuaj.
- Kev hloov kho txheej txheem Nano-silica, nrog rau qhov zoo ntawm kev txhim kho cov khoom siv kho tshuab thiab kev ua haujlwm, muaj ntau yam kev cia siab hauv thaj chaw ntawm Cov Khoom Siv Sib Xyaws thiab kev tiv thaiv ib puag ncig.
Kev tshawb fawb yav tom ntej tuaj yeem ua kom zoo dua cov txheej txheem hloov kho thiab tshawb nrhiav cov txiaj ntsig synergistic ntawm ntau txoj kev hloov kho kom tau raws li qhov xav tau ntawm ntau daim ntawv thov.
