Nomex ni iki? Fibre ya Aramid idapfa gushya
Abazimya umuriro n'abashoferi b'imodoka zisiganwa barabyiringira, abahanga mu by'ikirere n'abasirikare barabyishingikirizaho—none se ibanga riri inyuma y'imyenda ya Nomex ni irihe? Ese iboshywe mu bipimo by'ikiyoka, cyangwa ni umuhanga mu gukina n'umuriro? Reka duhishure ubumenyi buri inyuma y'iki cyamamare kirwanya umuriro!
▶ Intangiriro y'ibanze y'imyenda ya Nomex
Imyenda ya Nomex
Nomex Fabric ni fibre ya aramid ikora neza kandi idacana umuriro yakozwe na DuPont (ubu ni Chemours) muri Leta Zunze Ubumwe za Amerika.
Itanga ubushobozi bwo kwihanganira ubushyuhe budasanzwe, kwirinda umuriro, no kudacika intege mu mikorere ya shimi—itwika aho gushya iyo ihuye n’umuriro—kandi ishobora kwihanganira ubushyuhe bugera kuri 370°C mu gihe ikomeza kuba yoroshye kandi ihumeka.
Nomex Fabric ikoreshwa cyane mu myenda yo kuzimya umuriro, imyenda ya gisirikare, imyenda yo kwirinda ikoreshwa mu nganda, ndetse n'imyenda yo gusiganwa ku magare, ikaba yaramenyekanye nk'ikimenyetso cy'agaciro mu mutekano bitewe n'imikorere yayo yizewe yo kurokora ubuzima mu bidukikije bikomeye.
▶ Isesengura ry'Imiterere y'Ibikoresho by'Umwambaro wa Nomex
Imiterere yo kurwanya ubushyuhe
• Igaragaza ko umuriro udakora neza binyuze mu buryo bwa karuboni ku bushyuhe bwa 400°C+
• LOI (Ikigero cy'umwuka wa ogisijeni ugabanya) irenga 28%, igaragaza imiterere yo kuzimya ubwayo
• Ubushyuhe bugabanuka <1% kuri 190°C nyuma y'iminota 30 yo kubyimbirwa
Imikorere ya tekiniki

Guhagarara kw'ibinyabutabire
• Irwanya ibintu byinshi bivangwa n'ibinyabuzima (benzene, acetone)
• Ingano y'ubudahangarwa bwa pH: 3-11
• Ubudahangarwa bwa hydrolysis buruta ubundi bwoko bwa aramid
Ibiranga kuramba
• Ubudahangarwa ku kwangirika kwa UV: <5% by'ingufu nyuma yo kwangirika amasaha 1000
• Ubudahangarwa bw'uburibwe bugereranywa na nylon yo mu rwego rw'inganda
• Ihangana n'imashini zisaga 100 zo gukaraba mu nganda nta kwangirika kw'imikorere

Ubuyobozi bw'Ingufu nziza za Laser zo Gukata Imyenda
Muri iyi videwo, turabona ko imyenda itandukanye yo gukata hakoreshejwe laser isaba imbaraga zitandukanye zo gukata hakoreshejwe laser, kandi tukiga uburyo bwo guhitamo imbaraga za laser ku bikoresho byawe kugira ngo ubone imbogamizi nziza kandi wirinde ibisebe bitwikwa.
0 ikosa: nta gusibangana kw'imigozi n'impande zigoye, imiterere igoye ishobora gukorwa ukoresheje gukanda rimwe. Ingufu ebyiri: yihuta inshuro 10 kurusha akazi k'amaboko, igikoresho cyiza cyo gukora ibintu byinshi.
Nigute wakata imyenda ya Sublimation? Kamera ikata laser ku myenda ya siporo
Yagenewe gukata imyenda icapwa, imyenda ya siporo, imyenda y'imyenda, imyenda y'imyambaro, amabendera y'amarira, n'indi myenda ifite ishusho y'umutuku.
Nk'imyenda ya polyester, spandex, lycra, na nylon, ku ruhande rumwe, iza ifite ubushobozi bwo gukoresha sublimation, ku rundi ruhande, ifite ubushobozi bwo gukata laser neza.

▶ Ibibazo Bikunze Kubazwa na Nomex Fabric
Igitambaro cya Nomex nimeta-aramidfibre y'ubukorikori yakozwe naDuPont(ubu ni Chemours). Yakozwe muripoly-meta-phenylene isophthalamide, ubwoko bwa polymeri irinda ubushyuhe kandi irinda umuriro.
Oya,NomexnaKevlarntabwo ari bimwe, nubwo byombi ariinsinga za aramideyakozwe na DuPont kandi isangiye imiterere imwe n'imwe.
Yego,Nomex irinda ubushyuhe cyane, bigatuma iba amahitamo meza yo gukoresha aho kurinda ubushyuhe bwinshi n'inkongi z'umuriro ari ingenzi cyane.
Nomex ikoreshwa cyane kubera kokurwanya ubushyuhe cyane, kurinda inkongi z'umuriro, no kurambamugihe iguma yoroshye kandi imeze neza.
1. Ubudahangarwa bw'umuriro n'ubushyuhe butagira urugero
Ntishonga, ntitonyanga cyangwa ngo itwikebyoroshye—ahubwo, niikoreshwa rya karuboneiyo habayeho inkongi z'umuriro, bigatera uruzitiro rurinda.
Ihangana n'ubushyuhe kugeza kuUbushyuhe bugera kuri 370°C (700°F), bigatuma iba nziza cyane ahantu hashobora gushya n'inkongi z'umuriro.
2. Kwizimya no kubahiriza amahame y'umutekano
IkurikizaNFPA 1971(ibikoresho byo kuzimya umuriro),EN ISO 11612(uburinzi bw'ubushyuhe mu nganda), naKURE 25.853(ubushyuhe bw'indege).
Ikoreshwa mu bikorwa ahoinkongi z'umuriro, imirasire y'amashanyarazi, cyangwa imirasire y'icyuma cyashongeshejweni ibyago.
3. Yoroshye kandi yoroshye kwambara igihe kirekire
Bitandukanye na asbestos nini cyangwa fiberglass, Nomex niguhumeka no koroha, biha uburenganzira bwo kugenda mu kazi gafite ibyago byinshi.
Akenshi bivanze naKevlarkugira ngo wongere imbaraga cyangwairangi ririnda ibarakugira ngo bigire akamaro.
4. Kuramba no Kurwanya Ubutabire
Irakomeza guhanganaamavuta, imiti ishongesha, n'imiti ikoreshwa mu ngandakurusha imyenda myinshi.
Arwanyagushwanyaguza no gukaraba kenshihatabayeho gutakaza ubushobozi bwo kurinda.
