Dab tsi yog Aramid Fiber

Aramid Fiber ntau

Aramid fiber, raws li ib tug tshiab high-tech hluavtaws fiber ntau, nrog rau cov khoom zoo heev ntawm lub zog siab, siab modulus, tshav kub resistant, acid thiab alkali resistant, lub teeb yuag thiab lwm yam. Lub zog ntawm aramid fiber yog 5 mus rau 6 lub sij hawm siab tshaj hlau. hlau tab sis qhov hnyav tsuas yog 1/5 ntawm steel hlau. Lub modulus yog 2 mus rau 3 npaug ntawm cov hlau hlau los yog iav fiber ntau, toughness yog 2 npaug ntawm cov hlau hlau. Ntawm 560 degrees, nws tsis decompose thiab yaj. Nws muaj kev ua haujlwm zoo thaum tshav kub kub ua haujlwm thiab tiv thaiv kev laus thiab muaj lub neej ntev. Qhov tshwm sim ntawm aramid yog suav tias yog ib qho tseem ceeb ntawm cov txheej txheem keeb kwm hauv kev lag luam khoom siv.

Cov khoom siv zoo: Nws yog ib hom kev hloov pauv ntawm cov polymer, lub zog tawg yog siab dua li cov polyester zoo tib yam, paj rwb, nylon, thiab lwm yam, loj elongation, muag muag, zoo spinnability, tuaj yeem tsim rau hauv staple fibers thiab filaments ntawm ntau qhov sib txawv thiab ntev, ces woven rau hauv sib txawv yarn woven fabric, non-woven fabric los ntawm textile machinery, tom qab ua tiav, kom tau raws li qhov yuav tsum tau ntawm txawv teb ntawm kev tiv thaiv khaub ncaws.

Cov nplaim hluav taws zoo heev, tiv thaiv tshav kub: Cov fiber ntau no tiv taus cua sov thiab tuaj yeem tiv taus kub txog 500 degrees. Qhov no ua rau nws muaj lub siab xav siv rau hauv cov ntawv thov xws li aerospace, tsheb, thiab kev tiv thaiv kev lag luam uas muaj qhov kub thiab txias.

Cov khoom siv tshuaj ruaj khov: Aramid muaj kev tiv thaiv zoo rau feem ntau cov tshuaj lom neeg, tuaj yeem tiv taus feem ntau ntawm cov tshuaj inorganic acids, kuj zoo alkali tsis kam ntawm chav tsev kub.

Cov yam ntxwv sib sib zog ua rau nws zoo meej rau siv rau hauv cov pob khoom uas qhov hnyav yog qhov kev txhawj xeeb, xws li cov dav hlau thiab qhov siab helicopter.
