Polyester ua hauj lwm zoo txhim kho qhov kub siab ruaj khov

1. Txhim kho qhov kub thiab ruaj khov ruaj khov thiab ruaj khov. Vim yog qhov peb-seem faib ntawm polyester fiber monofilament, nws muaj muaj zog adsorption rau asphalt thiab tsis yog entangled. Nws tuaj yeem nqus tau ntau dhau dawb asphalt kom ua rau asphalt nplaum. Cov kev sib koom ua ke thiab cov cohesion tau nce ntxiv. Nyob rau tib lub sijhawm, vim kev ua lub ntsej muag thaib kev txhawb nqa thiab kev sib tsoo, cov npliag 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 tuaj, thiab cov fiber ntau asphalt pob zeb yog ruaj khov. Cov degree tau zoo dua.

2. Txhim kho cov tshuaj tiv thaiv qis-qhov kub thiab tsis haum thiab kev nqus ntawm cov fiber ntau rau asphalt, uas ua rau kom qhov nce ntawm cov ntsiab lus zoo tshaj plaws hauv asphalt pob zeb. Cov ntsiab lus siab asphalt ntau dua ua rau cov fiber ntau asphalt sib xyaw ua kom zoo thiab ua kom qis dua qhov kub qis ntawm -40 ℃. Lub zog tensile, zoo tiv thaiv shrinkage kev nyuaj siab, txhim kho qis-kub tawg tsis kam ntawm qhov sib xyaw, txo cov cim ntawm qhov kub thiab txias shrinkage tawg thiab tiv thaiv kev txhim kho ntawm kev xav ntawm tawg.

3. Txhim kho kev qaug zog tsis kam. Asphalt pavement yog raug rau kev rov ua tiav ntawm lub log thauj khoom raws li qhov kev txiav txim ntawm ib puag ncig kub sab nraud. Thaum qhov rov ua dua ntawm lub nra dhau ntawm qee qhov ntawm lub sijhawm, qhov kev ntxhov siab tsim nyob rau hauv txoj kev pua hauv qab lub nra yuav dhau tus txheej txheem tsis kam ntawm lub zog txo. Cov kab nrib pleb tshwm ntawm txoj kev saum npoo, uas ua rau nkees nkees. Tom qab ntxiv cov polyester fiber, cov teeb tsa kev faib ua ke ntawm fiber ntau monofilament hauv kev sib xyaw ua ke yuav ua rau nws txoj kev txhav txhav thiab txhim kho qhov qaug zog tsis kam ntawm asphalt pob zeb.

4. Txhim kho kev ruaj ntseg dej. Dej ruaj khov ntawm asphalt pavement yog hais txog qhov cuam tshuam dhau los ntawm kev thauj khoom thiab qhov kub hloov pauv ntawm qhov asphalt pavement nyob ntawm cov dej. Qhov sib ntxiv ntawm cov polyester fiber tuab ua ke rau asphalt zaj duab xis, txo lub zog ntawm cov dej-hloov asphalt, thiab txo cov dej nkag rau hauv cov asphalt pob zeb. Ua ke nrog cov adsorption ntawm lub fiber, qhov viscosity ntawm asphalt nce, uas txhim kho cov asphalt thiab asphalt. Lub zog sib xyaw ua ke ntawm cov khoom sib zog ua kom muaj peev xwm ntawm qhov sib xyaw ua yeeb yaj kiab tsim los ntawm asphalt thiab qhov sib koom ua ke hauv asphalt sib xyaw kom tiv thaiv kev ya raws, yog li txhim kho dej ruaj ntseg ntawm kev sib xyaw asphalt.
