Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog cov ntsiab lus ntawm aramid. aramid yog tsim los ntawm cov saw ntev ntawm cov molecules uas txuas ua ke los ntawm cov ntawv cog lus muaj zog hydrogen. Cov ntawv cog lus no muab aramid nws lub zog tshwj xeeb thiab ua rau nws tiv taus qhov cuam tshuam thiab puncture. Txawm li cas los xij, aramid tsis yog impervious rau kev txiav thiab txiav, tshwj xeeb tshaj yog thaum nws raug rau cov ntse lossis serrated npoo.
Txhawm rau txiav txim siab seb aramid puas tuaj yeem txiav nrog rab riam, nws yog ib qho tsim nyog yuav tsum xav txog yam tshwj xeeb ntawm riam siv. Ib tug ntse, serrated riam nrog ib tug jagged ntug yog feem ntau txiav los ntawm aramid tshaj ib tug du-edged riam. Qhov no yog vim lub jagged ntug ntawm riam tuaj yeem yooj yim tuav thiab rub tawm cov fibers ntawm aramid, ua rau nws tawg thiab nws thiaj li tsim kua muag.
Ntxiv nrog rau hom riam siv, lub thickness thiab ntom ntawm cov khoom siv aramid kuj ua lub luag haujlwm hauv nws txoj kev tiv thaiv kev txiav. Thicker thiab ntau ntom ntom aramid fabrics feem ntau nyuaj rau txiav dua li cov ntaub nyias nyias los yog xoob xoob. Qhov ceev ntawm lub weave cuam tshuam rau tus nqi ntawm lub zog uas yuav tsum tau txiav los ntawm cov ntaub, nrog rau cov degree ntawm fraying uas tshwm sim thaum cov ntaub raug txiav.
Thaum kawg, thaum aramid yog ib qho khoom siv ruaj khov thiab ruaj khov, nws tsis yog qhov tsis zoo rau kev txiav. Ib rab riam ntse ntse tuaj yeem txiav los ntawm aramid, tshwj xeeb tshaj yog thaum cov ntaub nyias nyias lossis xoob xoob. Txawm li cas los xij, rau feem ntau cov kev siv ntawm aramid-raws li cov khoom, xws li lub cev armor lossis tiv thaiv khaub ncaws, theem ntawm kev tiv thaiv kev txiav yog txaus los muab kev tiv thaiv zoo tiv thaiv kev raug mob.
Hauv kev xaus, thaum aramidis yog cov khoom siv tiv taus thiab ruaj khov, nws tsis muaj kev tiv thaiv tag nrho rau kev txiav. Qhov tsis kam ntawm aramis rau kev txiav yog cuam tshuam los ntawm cov yam ntxwv xws li hom riam siv, tuab thiab ntom ntawm cov khoom siv aramid, thiab cov ntawv thov tshwj xeeb rau cov khoom siv. Yog li ntawd, nws yog ib qho tseem ceeb kom ua tib zoo xav txog cov yam ntxwv no thaum xaiv cov khoom siv aramid rau kev tiv thaiv kev raug mob.
