Aramid Fiber ine Yakakwira Simba uye Yakanakisa Kupisa / Kuramba Kwemoto
KEVLAR® (Para aramids)
Mapara aramids -akadai seKevlar®- anozivikanwa nekuda kwesimba rawo rinoshamisa uye nekupisa kwakanyanya / murazvo kuramba.Iyo yakakwirira yecrystallinity yemafibhi ndiyo hunhu hukuru hwemuviri hunotamisa iyi yakanakisa simba risati raputsika.
Meta-Aramid (Nomex®)
Meta aramids akasiyana e polyamide ane akanyanya kupisa / murazvo kuramba.Ivo vane yakanakisa abrasion kuramba uye kuramba kune kuparara kwemakemikari.

Kusiyana nezvimwe zvinhu uye fiber, izvo zvingada mabhanhire uye kupera kuti zviwedzere kupisa kwavo uye / kana kuchengetedzwa kwemurazvo, Kevlar® neNomex® fibers dzinogara dzichidzivirira moto uye haizonyunguduke, kudonha, kana kutsigira kupisa.Mune mamwe mazwi, kudzivirira kwemafuta kunopihwa neKevlar® neNomex® ndeyekusingaperi - kupikisa kwayo kwepamusoro kwemurazvo hakugone kugezwa kana kupera.Zvishandiso zvinofanirwa kurapwa, kuitira kuti vavandudze mashandiro avo ekudzivirira moto (uye dziviriro yavo inogona kupera nekugezwa nekupfeka kuratidzwa) inozivikanwa se "inodzivirira moto."Avo vane kuchengetedzwa kwepamusoro uye kwechigarire (kureva, Kevlar®, Nomex®, nezvimwewo) vanonzi "kudzivirira moto."
Uku kupisa kwepamusoro uye kugona kudzivirira murazvo kunobvumira aya mafibhi - uye machira anogadzirwa kubva mazviri - kusangana neakawanda indasitiri zviyero zveindasitiri izvo zvimwe zvinhu hazvigone.
Mafibhi ese ari maviri anoshandiswa (akazvimiririra uye akasanganiswa) kune akawanda akawanda ezvigadzirwa muminda yakadai se:
- Kurwisa moto
- Defense
- Kugadzira uye Kunyungudika
- Welding
- Zvemagetsi uye Utility
- Mining
- Mujaho
- Aerospace uye Outer space
- Kunatsa uye Kemikari
- Uye vamwe vakawanda
Sezvo nekushanda kwese kwepamusoro-soro fibers, zvose Nomex® neKevlar® zvine utera hwavo uye zvisingakwanisi.Semuenzaniso, ese ari maviri anozopedzisira adzikira mukuita uye muruvara, nekuratidzwa kwenguva refu kune UV mwenje.Pamusoro pezvo, semidziyo ine porous, ivo vanotora mvura / hunyoro, uye vanowana huremu pavanotora mvura.Naizvozvo, kana uchiongorora faibha (s) yeimwe application, zvinogara zvakakosha kuti titarise zvese zvingaite zviito, nharaunda, uye nguva iyo iyo yekupedzisira chigadzirwa ichaburitswa.
