Aramid (Kevlar) fiber ntau cov ntaub ntawv Ua tau zoo thiab cov yam ntxwv Nrog ultra-siab zog, siab modulus thiab siab kub tsis kam, acid thiab alkali tsis kam, lub teeb thiab lwm yam kev ua tau zoo, nws lub zog yog 5-6 zaug ntawm cov hlau xaim, cov qauv yog 2-3 lub sij hawm ntawm cov hlau xaim lossis iav fiber ntau, nws qhov tawv yog 2 zaug ntawm cov hlau xaim thaum nws tsuas hnyav txog li 1/5 ntawm cov hlau tsis xeb. Hauv ib puag ncig ntawm 560 temperature temperature nws tsis lwj thiab yaj. Kuv t muaj lub rwb thaiv tsev zoo thiab tiv thaiv kev laus nrog cov kev pab lub neej ntev. nws muaj tsawg ntom ntom, siab zog, thiab zoo corrosion kuj. Nws tuaj yeem siv hauv kev tsim cov foob pob hluav taws foob pob zeb, lub dav hlau, lub dav hlau fuselages, lub dav tis, tw tis thiab lwm yam khoom siv dav dav pob tshab thiab cov txheej txheem qauv uas tuaj yeem tiv taus kev cuam tshuam ntawm cov quab yuam. Tus cob-kho siv tam cov khoom sib xyaw ua los ntawm aramid fiber ntau siv nyob rau hauv lub dav hlau tus qhua lub cev, uas tuaj yeem txo qhov hnyav tag nrho ntawm lub dav hlau. Cov tsho khiab mos txwv thiab mos txwv lub kaus mom ua los ntawm aramid fiber ntau tuaj yeem hloov lub tsho qub ntawm nylon thiab lub tog raj kheej steel kaus mom. Ntxiv cov nqi tsim nyog ntawm aramid mus rau tsho khuam tsho lub kaus mom thiab lub kaus mom tsis yog tuaj yeem ua rau lawv me me thiab pom kev xwb, tabsis tseem ua rau kom cov mos txwv ua haujlwm tau txog 40%. Thiab nws muaj zoo dua ballistic tsis kam thiab kub tsis kam tshaj ultra-high molecular phaus polyethylene fibers. Kev siv lub siab kub ua hauj thiab tiv taus kev kub ntxhov ntawm aramid fiber.
Cia:Nws raug nquahu tias cov khoom lag luam yog khaws cia hauv qhov chaw txias thiab qhuav. Pom zoo rau qhov ntsuas kub ntau ntawm 10-30 ℃ thiab cov av noo txheeb ze ntawm 50-75%. Cov khoom yuav tsum nyob twj ywm hauv cov khoom ntim kom txog thaum tsuas yog ua ntej siv. Cov kab ntim khoom yuav tsum yog ib qho av siab.
