Ibiranga impapuro aramid
Kumara igihe kirekire. Ikintu kigaragara cyane muri aramid 1313 nubushyuhe bwo hejuru bwo kurwanya ubushyuhe, bushobora gukoreshwa igihe kirekire ku bushyuhe bwo hejuru bwa 220 ℃ udasaza. Ibikoresho byamashanyarazi nubukanishi birashobora kubungabungwa kugeza kumyaka 10, kandi ihagaze neza ni nziza. Hafi ya 250 ℃, igipimo cyacyo cyo kugabanya ubushyuhe ni 1% gusa; Guhura nigihe gito nubushyuhe bwo hejuru bwa 300 ℃ ntibizatera kugabanuka, gushira, koroshya, cyangwa gushonga; Gusa itangira kubora kubushyuhe burenze 370 ℃; Carboneisation itangira hafi 400 ℃ - ubwo buryo bwo hejuru bwumuriro ntibusanzwe muri fibre irwanya ubushyuhe.
Ishema ry'umuriro. Ijanisha rya ogisijene isabwa kugirango ibintu bitwike mu kirere byitwa igipimo cya ogisijeni ntarengwa, kandi uko igipimo cya ogisijeni ntarengwa, niko imikorere yacyo idindiza. Ubusanzwe, umwuka wa ogisijeni uri mu kirere ni 21%, mu gihe igipimo cya ogisijeni ntarengwa ya aramide 1313 irenze 29%, bigatuma iba fibre-retardant fibre. Kubwibyo, ntabwo izashya mu kirere cyangwa imfashanyo yo gutwikwa, kandi ifite ibintu byo kuzimya. Iyi miterere yihariye ikomoka kumiterere yayo ya molekuline ituma aramid 1313 idacana burundu, bityo ikaba izwi nka "fibre fibre".
Amashanyarazi meza cyane. Aramide 1313 ifite dielectric ihoraho cyane kandi imbaraga zayo za dielectric zifasha kugumana amashanyarazi meza cyane mubushyuhe bwinshi, ubushyuhe buke, nubushuhe bwinshi. Impapuro zokwirinda zateguwe hamwe nazo zirashobora kwihanganira kugabanuka kumashanyarazi kugera kuri 40KV / mm, bigatuma iba ibikoresho bizwi kwisi yose.
Imiti idasanzwe. Imiterere yimiti ya aramid 1313 irahagaze neza cyane, irwanya kwangirika kwinshi kwa acide organique nindi miti, kandi irwanya hydrolysis hamwe na ruswa.
Ibikoresho byiza bya mashini. Aramid 1313 nigikoresho cyoroshye cya polymer gifite ubukana buke no kuramba cyane, biha kuzunguruka kimwe na fibre isanzwe. Irashobora gutunganyirizwa mumyenda itandukanye cyangwa imyenda idoda ikoresheje imashini zisanzwe zizunguruka, kandi irwanya kwambara kandi irira amarira, hamwe nibisabwa byinshi.
Kurwanya imirasire ikomeye. Aramide 1313 irwanya α 、 β 、 χ Imikorere yimirasire ituruka kumirasire numucyo ultraviolet nibyiza. Ukoresheje 50Kv χ Nyuma yamasaha 100 yimirasire, imbaraga za fibre zagumye kumurongo wambere 73%, mugihe polyester cyangwa nylon byari bimaze guhinduka ifu.
