Dab tsi yog qhov txawv ntawm aramid thiab polyester?
Aramid thiab polyester yog ob hom hluavtaws fibers uas yog siv nyob rau hauv ntau yam kev siv los ntawm cov khaub ncaws mus rau cov khoom siv. Txawm hais tias lawv yuav zoo sib xws thaum xub thawj siab ib muag, lawv muaj qee qhov sib txawv tseem ceeb uas ua rau lawv sib nrug.
Kev sib xyaw thiab cov khoom
Ib qho ntawm qhov sib txawv ntawm aramid thiab polyester yog lawv cov muaj pes tsawg leeg thiab cov txiaj ntsig tau. Aramid fibers, tseem hu ua aromatic polyamide fibers, yog tsim los ntawm ib pab pawg neeg ntev-chain hluavtaws polymers uas muaj ib tug tshwj xeeb molecular qauv. Cov qauv no muab aramid fibers lawv lub zog tshwj xeeb thiab kub ua haujlwm.
Polyester fibers, ntawm qhov tod tes, yog tsim los ntawm hluavtaws polymers muaj li ntawm ester pawg. Thaum polyester fibers yog ruaj thiab resistant rau abrasion, lawv tsis muaj zog los yog kub resistant li aramid fibers.
Lub zog thiab Durability
Vim lawv cov qauv molecular tshwj xeeb, aramid fibers muaj zog heev thiab ruaj khov. Qhov tseeb, aramid fibers yog cov muaj zog hluavtaws fibers muaj, nrog lub zog tensile uas yog tsib npaug ntau dua hlau. Aramid fibers kuj muaj kev tiv thaiv zoo rau kev puas tsuaj, ua rau lawv zoo tagnrho rau kev siv hauv cov ntawv thov kev ntxhov siab xws li cov tsho tiv thaiv mos txwv thiab cov log tsheb sib tw.
Polyester fibers, thaum tsis muaj zog li aramid fibers, tseem muaj zog thiab tiv taus hnav thiab tsim kua muag. Lawv feem ntau siv rau hauv cov khaub ncaws thiab kis las, nrog rau cov hlua thiab hlua.
Thaum tshav kub kub Resistance
Lwm qhov sib txawv tseem ceeb ntawm aramid thiab polyester yog lawv cov cua sov. Aramid fibers yog cov resistant rau kub thiab nplaim taws, ua rau lawv zoo tagnrho rau siv nyob rau hauv hluav taws-resistant khaub ncaws thiab tiv thaiv iav. Lawv kuj muaj qhov qis thermal shrinkage tus nqi, uas tso cai rau lawv tswj lawv cov duab thiab lub zog txawm tias raug kub kub.
Polyester fibers, thaum tshav kub-resistant, tsis yog nplaim taws-resistant li aramid fibers. Lawv kuj muaj cov thermal shrinkage ntau dua, uas tuaj yeem ua rau lawv muaj kev sib hloov lossis hloov pauv thaum raug kub siab.
Tshuaj tiv thaiv
Aramid fibers yog cov tshuaj tiv thaiv zoo heev, ua rau lawv zoo tagnrho rau kev siv cov iav tiv thaiv thiab lwm yam kev siv uas raug rau cov tshuaj lom neeg muaj kev txhawj xeeb. Lawv tiv taus ntau cov kua qaub, cov hauv paus, thiab cov kuab tshuaj thiab tuaj yeem tiv taus qee cov oxidizing cov neeg ua haujlwm.
Polyester fibers, thaum tseem tshuaj-resistant, tsis zoo li aramid fibers nyob rau hauv no hais txog. Lawv feem ntau tiv taus cov kua qaub thiab cov hauv paus tab sis tuaj yeem puas lossis degraded los ntawm qee cov kuab tshuaj thiab oxidizing cov neeg ua haujlwm.
Nqi
Tus nqi ntawm aramid thiab polyester fibers tuaj yeem sib txawv heev nyob ntawm daim ntawv thov thiab hom fiber ntau. Feem ntau hais lus, aramid fibers yog kim dua polyester fibers vim lawv cov qauv molecular tshwj xeeb thiab lub zog tshwj xeeb thiab kub tsis kam.
Daim ntawv thov
Aramid fibers yog siv nyob rau hauv ntau yam kev siv, nrog rau kev tiv thaiv khaub ncaws, sib tw log tsheb, thiab aerospace cov ntaub ntawv. Lawv kuj feem ntau siv rau hauv cov ntawv thov kev ntxhov siab xws li hlua thiab cables, nrog rau cov tsho tiv thaiv mos txwv thiab lwm yam khoom siv tiv thaiv tus kheej.
Polyester fibers yog siv nyob rau hauv ntau yam kev siv thiab, los ntawm cov khaub ncaws thiab kis las kis las mus rau hlua thiab hlua. Lawv kuj feem ntau siv rau hauv cov khoom siv xws li conveyor siv thiab pom tshuab.
Xaus
Hauv kev xaus, aramid thiab polyester fibers yog ob hom hluavtaws fibers nrog cov khoom tshwj xeeb thiab kev siv. Thaum aramid fibers muaj zog dua, kub-tiv taus, thiab feem ntau muaj tshuaj tiv thaiv ntau dua li polyester fibers, polyester fibers tseem muaj zog thiab muaj tus nqi qis dua. Kev nkag siab txog qhov sib txawv ntawm ob hom fibers no tuaj yeem pab cov neeg tsim khoom thiab cov neeg siv khoom xaiv cov khoom tsim nyog rau lawv cov kev xav tau tshwj xeeb.
