Polyester Mat

Polyester levmuaj cov khoom zoo heev, xws li siab tawg lub zog thiab elastic modulus, nruab nrab resilience, zoo heev kub teeb nyhuv, zoo tshav kub kuj thiab lub teeb tsis kam. Lub melting point ntawm lubpolyester levyog hais txog 255 degree, thiab lub iav hloov pauv kub yog li 70 degree. Nws yog ruaj khov nyob rau hauv cov duab nyob rau hauv ib tug ntau yam ntawm kawg-siv tej yam kev mob, thiab cov ntaub yog washable thiab hnav. Tsis tas li ntawd, polyester lev kuj muaj qhov ua tau zoo heev (xws li tsis kam mus rau cov kuab tshuaj organic, xab npum, thiab lwm yam), tshuaj ntxuav tes, tshuaj dawb, oxidant) thiab zoo corrosion kuj, ruaj khov rau qaug zog acid, alkali, thiab lwm yam, yog li nws muaj qhov dav. ntau yam khoom noj thiab kev siv khoom siv. Txoj kev loj hlob sai ntawm kev lag luam roj av kuj tau muab ntau thiab pheej yig raw khoom rau kev tsim cov polyester fibers. Tsis tas li ntawd, txoj kev loj hlob ntawm technologies xws li chemical engineering, machinery, thiab electronics self-control technology nyob rau hauv xyoo tas los no tau maj mam paub txog cov txheej txheem luv luv ntawm cov khoom siv raw, kev tsim fiber ntau, thiab kev ua haujlwm. Polyester fiber ntau tau dhau los ua kev loj hlob sai thiab siab tshaj plaws-yielding hluavtaws fiber ntau. Nyob rau hauv 2010, lub ntiaj teb no polyester fiber ntau tso zis mus txog 37.3 lab tons, accounting rau 74 feem pua ​​ntawm lub ntiaj teb no tag nrho cov hluavtaws fibers.

1. Txhim kho qhov kub thiab txias ruaj khov thiab ua kom muaj qhov kub thiab txias. Vim yog peb-dimensional tis ntawm polyester fiber monofilaments, nws muaj zog adsorption nrog asphalt thiab tsis entangle. Nws tuaj yeem nqus tau ntau dhau asphalt dawb thiab ua kom cov viscosity ntawm asphalt. Nyob rau tib lub sij hawm, vim lub crisscross reinforcement thiab bridging nyhuv, kev khiav hauj lwm ntawm asphalt yog txo, lub lateral kev khiav hauj lwm los yog khiav ntawm aggregate yog txwv, lub siab kub stability yog zoo txhim kho, thiab stability ntawm fiber asphalt qhob degree tau lawm. kho tau zoo heev.

2. Txhim kho qhov kub thiab txias tsis kam, qhov adsorption ntawm fiber ntau rau asphalt, uas ua rau muaj kev nce hauv qhov zoo ntawm asphalt hauv asphalt qhob, thiab cov ntsiab lus ntau dua asphalt, kom cov fiber ntau asphalt sib xyaw tseem hloov tau thiab siab ntawm qhov kub tsis tshua muaj. ntawm -40 degree Siab tensile lub zog, zoo tiv thaiv shrinkage kev nyuaj siab, txhim khu qhov tsis tshua muaj kub tawg tsis kam ntawm cov sib tov, txo qhov tsim ntawm kub shrinkage tawg thiab tiv thaiv kev loj hlob ntawm reflective tawg.

3. Txhim kho kev tiv thaiv kev qaug zog kev ua haujlwm Asphalt pavement yog raug rov qab log loads nyob rau hauv qhov kev txiav txim ntawm sab nraud kub ib puag ncig. Thaum lub load rov qab rau ntau tshaj li ib lub sij hawm, qhov kev ntxhov siab tsim nyob rau hauv lub pavement nyob rau hauv lub load yuav ntau tshaj li cov qauv tsis kam ntawm lub zog txo. Cov kab nrib pleb tshwm rau ntawm txoj kev, ua rau qaug zog puas tsuaj. Tom qab ntxiv polyester fibers, qhov sib faib ntawm fiber ntau monofilaments nyob rau hauv cov sib tov ua rau kom cov tawv nqaij modulus thiab txhim kho qhov qaug zog tsis kam ntawm asphalt pob zeb.

4. Txhim kho dej ruaj khov Cov dej ruaj khov ntawm asphalt pavement hais txog kev rov ua haujlwm ntawm kev thauj mus los thiab qhov kub thiab txias nthuav dav thiab kev cog lus ntawm asphalt pavement nyob rau hauv cov dej. Qhov sib ntxiv ntawm polyester fibers thickens lub asphalt zaj duab xis, txo lub zog ntawm dej-tshem asphalt, thiab txo cov dej infiltrated rau hauv asphalt pob zeb. Tsis tas li ntawd, qhov adsorption ntawm fibers nce viscosity ntawm asphalt, uas txhim kho asphalt thiab asphalt. Lub zog sib txuas ntawm cov aggregate ntxiv dag zog rau lub peev xwm ntawm cov yeeb yaj kiab interface tsim los ntawm asphalt thiab sib sau ua ke hauv asphalt sib tov los tiv thaiv cov dej ntws tawm, yog li txhim kho cov dej stability ntawm asphalt sib tov.
