Txheej Txheem Cej Luam:
Yuav kom txhim kho qhov kev tiv thaiv kev hloov pauv kub siab, kev tiv thaiv kev puas tsuaj los ntawm dej noo, thiab kev ua kom lub zog ntawm txoj kev asphalt thaum lub sijhawm ua haujlwm ntev dua, Lub Chaw Haujlwm Tshawb Fawb thiab Tshuab ntawm Haining Municipality tau tso cai rau kev sim paving ntawm cov ntu tshwj xeeb raws Jiaxing-Shaoxing Expressway Haining Interchange Connector thiab Provincial Highway 08. Cov ntu sim siv cov qauv tsim uas muaj 20 cm cement-stabilized crushed stone subbase, 6 cm AC-20C asphalt concrete intermediate layer, thiab 4 cm AC-16C asphalt concrete surface course, nrogcov fiber basalt uas raug txiav ua tej daim me mesib xyaw rau hauv cov asphalt sib xyaw. Peb lub tuam txhab tau muab txhua yam khoom siv fiber rau qhov project no.
Txheej txheem cej luam khoom:
Cov fiber basalt uas raug txiavyog tsim los ntawm kev txiav cov xov basalt filament txuas ntxiv thiab yog coated nrog silane-based sizing agent. Raws li cov tshuaj fiber silicate ntuj, nws ua rau pom kev tiv thaiv tshuaj zoo heev, tshwj xeeb tshaj yog qhov zoo tshaj plaws alkali tsis kam, ua rau nws yog qhov zoo tagnrho hloov rau polyester thiab lignin fibers. Nws suav nrog ua rau muaj kev ruaj khov kub siab, tsis tshua muaj qhov tawg tsis kam, thiab kev ua haujlwm tiv thaiv kev qaug zog ntawm asphalt sib xyaw.
| Lub npe khoom | Lub zog tensile (MPa) | Cov qauv elastic (GPa) | Kev ntev (%) | Qhov Ceev (g/cm³) | Kev ua haujlwm kub ℃ |
| Cov fiber basalt | 3000-4000 | 80-100 | 2.7-3.4 | 2.7-2.8 | 600-700 |
Kev tsim kho txheej txheem cej luam:
Hauv qhov project no, siv lub tshuab pub fiber ntau los ntxiv fiber. Cov khoom siv ntsuas sib xyaw nrog lub tshuab sib tov, thiab cov fiber muab tso rau hauv lub lauj kaub sib tov ua ke nrog cov pob zeb kub. Thaum lub sijhawm tsim kho, cov fiber ntau raug tswj hwm nruj me ntsis, uas yog li 3 kg ib lub cubic meter ntawm cov khoom sib tov, kom ntseeg tau tias kev nqus asphalt sib npaug thiab qhov sib piv roj-pob zeb ruaj khov. Qhov kub sib tov raug tswj hwm ntawm 155-165 ℃. Tom qab txoj kev paving tiav lawm, nws yuav tsum tau cia sawv rau kev saib xyuas rau 24 teev lossis kom txog thaum qhov kub ntawm txoj kev qis dua 50 ℃ ua ntej nws tuaj yeem qhib rau kev tsheb khiav. Tag nrho ntawm 2.75 tons ntawm cov fibers basalt txiav tau siv rau hauv qhov project no.
Kev piav qhia luv luv ntawm qhov project:
Los ntawm kev paving ntawm qhov kev xeem no,cov fiber basalt uas raug txiav ua tej daim me metau pom ntau yam kev txhim kho hauv kev pavement asphalt.
1. Txhim kho qhov ruaj khov ntawm cov qauv: cov fibers tsim cov qauv network spatial hauv qhov sib tov los txhim kho cov khoom siv kho tshuab tag nrho;
2. Txhim kho lub peev xwm los tiv thaiv kev puas tsuaj los ntawm dej: ua kom cov zaj duab xis asphalt tuab dua, txo cov tev tawv, thiab txhim kho kev ruaj khov ntawm dej;
3. Txhim kho qhov kub thiab txias: txhim kho qhov kub thiab txias tsis kam thiab tsis kam tawg tsawg;
4. Ua kom lub neej qaug zog ntev dua: ua kom qeeb txoj kev puas tsuaj ntawm cov asphalt sib xyaw thiab ua kom lub neej kev pabcuam ntev dua.
Ua ib yam khoom siv txhawb nqa ntsuab thiab siv tau zoo rau kev siv txoj kev, cov fiber basalt txiav muaj txiaj ntsig zoo rau kev txhawb nqa thiab kev cia siab rau kev siv.
