1, zoo mechanical zog
Aramid fiber ntau yog ib hom kev hloov pauv ntawm cov polymer, nws lub zog tawg yog siab dua li cov polyester zoo tib yam, paj rwb, nylon, thiab lwm yam., nws elongation yog loj, nws kov yog mos, thiab nws spinnability yog zoo.Nws tuaj yeem tsim rau hauv cov fibers luv luv thiab filaments nrog txawv deniers thiab ntev, uas tuaj yeem ua rau hauv cov ntaub thiab cov ntaub tsis-woven nrog cov xov paj sib txawv hauv cov tshuab textile.Tom qab ua tiav, nws tuaj yeem ua tau raws li cov kev cai ntawm cov khaub ncaws tiv thaiv hauv ntau qhov chaw.
2. Zoo heev nplaim retardancy thiab kub tsis kam.
Qhov limiting oxygen index (LOI) ntawm aramid fiber ntau dua 28, yog li nws yuav tsis txuas ntxiv hlawv thaum nws tawm hauv nplaim taws.Cov nplaim hluav taws kub nyhiab ntawm aramid fiber ntau yog txiav txim siab los ntawm nws tus kheej cov qauv tshuaj, yog li nws yog cov nplaim hluav taws kub nyhiab, thiab nws cov nplaim hluav taws kub hnyiab yuav tsis raug txo los yog poob vim siv sij hawm thiab sij hawm ntxuav.Aramid fiber ntau muaj thermal stability zoo, tuaj yeem siv tsis tu ncua ntawm 300 ℃, thiab tseem tuaj yeem tuav lub zog siab ntawm qhov kub siab tshaj 380 ℃.Aramid fiber ntau muaj qhov kub siab decomposition, thiab nws yuav tsis yaj los yog poob ntawm qhov kub thiab txias, thiab nws yuav maj mam carbonize thaum kub siab tshaj 427 ℃.
3. Cov khoom siv tshuaj ruaj khov
Aramid fiber ntau muaj kev tiv thaiv zoo rau feem ntau cov tshuaj, feem ntau cov ntsiab lus siab inorganic acids thiab zoo alkali tsis kam ntawm chav tsev kub.
4. Kev tiv thaiv hluav taws xob
Aramid fiber ntau muaj hluav taws xob zoo heev.Piv txwv li, nyob rau hauv lub sij hawm ntev irradiation ntawm 1.2 × 10-2 w / in2 ultraviolet rays thiab 1.72 × 108rads gamma rays, nws qhov kev siv tseem tsis hloov.
5. Durability
Aramid fiber ntau muaj kev sib txhuam zoo heev thiab tshuaj lom neeg ua haujlwm.Tom qab 100 zaus ntawm kev ntxuav, lub zog tawg ntawm txoj hlua, ribbon lossis daim ntaub ua tiav los ntawm aramid fiber tseem tuaj yeem ncav cuag 85% ntawm lub zog qub.
