Lub luag haujlwm tseem ceeb ntawm polyester fiber
1.Txhob tiv thaiv qhov kub thiab txias siab thiab ruaj khov. Vim hais tias ntawm peb-seem kev faib tawm ntawm polyester fiber monofilament, nws muaj muaj zog adsorption nrog asphalt, thiab tsis co. Nws tuaj yeem adsorb ntau dhau hle dawb, ua rau lub viscosity ntawm asphalt. Muaj kev ruaj khov thiab kev sib koom ua ke. Nyob rau tib lub sijhawm, vim qhov ua tiav cov dej khov thiab cov thaiv kev, cov dej ua haujlwm ntawm cov asphalt raug txo, qhov cuam tshuam tom qab lossis ntws ntawm qhov sib koom ua ke raug txwv, qhov kub siab ruaj khov tau zoo dua, thiab cov fiber ntau asphalt pob zeb yog ruaj khov. Qib kawm tau zoo heev.
2. Tshaj tawm qhov kub tsis tshua muaj tawg tawg, fiber adsorption ntawm asphalt, ua rau muaj kev nce qib siab ntawm asphalt hauv asphalt pob zeb, cov ntsiab lus asphalt siab dua, kom cov fiber ntau asphalt tseem tseem ua haujlwm yooj thiab kub ntawm -40 ℃ Tensile lub zog, zoo tsis kam mus rau shrinkage kev nyuaj siab, txhim kho qhov kub tsawg tawg tawg tsis kam ntawm qhov sib tov, txo qhov tshwm sim ntawm kub ntsws shrinkage tawg thiab tuaj yeem tiv thaiv kev txhim kho ntawm kev tawg.
3. Txhim kho cov kev tiv thaiv kev rog kom zoo Cov Asphalt pavement raug rau cov log rov qab ua haujlwm nyob hauv ib puag ncig sab nraud. Thaum lub thauj khoom tau thov ntau dua rau qee qhov ntau ntawm lub sijhawm, qhov kev ntxhov siab tsim tawm rau hauv kev lees ua hauv qab qhov kev thauj khoom yuav dhau tus txheej txheem tsis kam ua kom txo lub zog. Nws ua rau tawg rau ntawm txoj kev pavement, ua rau qaug zog ntawm pob txha lov. Tom qab cov polyester fiber ntxiv ntxiv, cov teeb tsa kev faib ua ke ntawm fiber ntau monofilament hauv kev sib xyaw ua ke nce cov qauv txhav thiab txhim kho qhov kev qaug zog ntawm cov asphalt pob zeb.
4. Txhim kho kev ruaj ntseg ntawm dej. Dej ruaj khov ntawm asphalt pavement yog hais txog kev rov ua dua ntawm kev npaj asphalt hauv qab qhov xwm txheej ntawm cov dej nyob hauv dej. Qhov sib ntxiv ntawm cov xov hluavtaws polyester ua rau asphalt zaj duab xis dua, txo lub zog ntawm cov dej-hloov asphalt, thiab txo cov nyiaj ntawm cov dej nkag rau asphalt pob zeb. Tsis tas li ntawd, cov adsorption ntawm cov fibers ua rau lub viscosity ntawm asphalt loj dua, uas ua rau kom asphalt thiab Lub zog sib xyaw ua ke ntawm lub zog ua kom lub peev xwm ntawm cov yeeb yaj kiab interface tsim los ntawm cov asphalt thiab qhov sib xyaw ua ke nyob rau hauv cov asphalt sib xyaw kom tiv taus lub ya raws peeling nyhuv. , yog li txhim kho cov dej ruaj ntseg ntawm cov asphalt sib tov.
