Raws li cov kws tshaj lij, hlau tau yog cov khoom siv tseem ceeb hauv cov haujlwm tsim kho tau ntau xyoo lawm, muab lub zog thiab kev ruaj khov tseem ceeb. Txawm li cas los xij, thaum tus nqi hlau txuas ntxiv nce siab thiab kev txhawj xeeb txog cov pa roj carbon dioxide nce ntxiv, muaj kev xav tau ntau ntxiv rau lwm txoj kev daws teeb meem.
Basalt rebaryog ib qho kev xaiv zoo uas tuaj yeem daws tau ob qho teeb meem. Ua tsaug rau nws cov yam ntxwv zoo heev thiab kev phooj ywg ib puag ncig, nws tuaj yeem hu ua lwm txoj hauv kev zoo rau cov hlau ib txwm muaj. Los ntawm pob zeb volcanic, basalt steel bars muaj lub zog tensile zoo kawg nkaus, ua rau lawv tsim nyog rau kev siv hauv ntau yam kev siv hauv kev tsim kho.
Basalt rebar yog ib qho kev xaiv uas tau ua pov thawj rau cov hlau ib txwm muaj lossis fiberglass reinforcement rau cov pob zeb ua vaj tse thiab tau txais kev txhawb nqa raws li cov thev naus laus zis tshiab hauv UK. Kev siv cov kev daws teeb meem tshiab no rau cov haujlwm siab xws li High Speed 2 (HS2) thiab M42 motorway tau dhau los ua qhov tseem ceeb hauv cov haujlwm tsim kho thaum cov kev siv zog decarbonisation nce qib.
- Cov txheej txheem tsim khoom suav nrog kev sau cov khoomroob hluav taws basalt, muab nws tsoo ua tej daim me me thiab tuav nws ntawm qhov kub txog li 1400°C. Cov silicates hauv basalt ua rau nws hloov mus ua kua uas tuaj yeem ncab los ntawm lub ntiajteb txawj nqus los ntawm cov phaj tshwj xeeb, tsim cov kab ntev uas tuaj yeem ncav cuag ntau txhiab meters ntev. Cov xov no ces raug qhwv rau ntawm cov spools thiab npaj los ua cov khoom txhawb nqa.
Pultrusion yog siv los hloov cov hlau basalt mus ua cov hlau rods. Cov txheej txheem no suav nrog kev rub cov xov tawm thiab muab lawv tso rau hauv cov kua epoxy resin. Cov resin, uas yog ib qho polymer, raug cua sov kom txog thaum nws ua kua thiab tom qab ntawd cov xov raug muab tso rau hauv nws. Tag nrho cov qauv khov sai sai, hloov mus ua ib lub pas nrig tiav hauv ob peb feeb xwb.
