Iyini i-Nomex? I-Aramid Fiber Engashisi
Abacishi bomlilo nabashayeli bezimoto zomjaho bayafunga ngakho, osomkhathi namasosha bathembele kukho—ngakho-ke iyini imfihlo ngemuva kwendwangu yeNomex? Ingabe ilukiwe ngezikali zedrako, noma imane nje inekhono lokudlala ngomlilo? Ake sithole isayensi ngemuva kwalesi sihlabani esimelana nomlilo!
▶ Isingeniso Esiyisisekelo Sendwangu Ye-Nomex
Indwangu ye-Nomex
I-Nomex Fabric iyi-fiber ye-aramid evikela ilangabi esebenza kahle kakhulu eyakhiwe yi-DuPont (manje eyi-Chemours) e-United States.
Inikeza ukumelana nokushisa okumangalisayo, ukuvikela umlilo, kanye nokuqina kwamakhemikhali—ukusha esikhundleni sokusha lapho ivezwa emalangabini—futhi ingamelana namazinga okushisa afinyelela ku-370°C ngenkathi ihlala ilula futhi ikwazi ukuphefumula.
I-Nomex Fabric isetshenziswa kabanzi emasudini okucisha umlilo, izingubo zempi, izingubo zokuzivikela zezimboni, kanye namasudini okugijima, ithola idumela layo njengendinganiso yegolide ngokuphepha ngenxa yokusebenza kwayo okuthembekile okusindisa impilo ezindaweni ezimbi kakhulu.
▶ Ukuhlaziywa Kwezakhiwo Zezinto Zendwangu ye-Nomex
Izakhiwo Zokumelana Nokushisa
• Ibonisa ukuvinjelwa komlilo okungokwemvelo ngokusebenzisa indlela yokwenza i-carbonization ku-400°C+
• I-LOI (Inkomba Yokukhawulela I-Oxygen) edlula u-28%, okubonisa izici zokuzicisha zona
• Ukuncipha kokushisa <1% ku-190°C ngemva kokuvezwa imizuzu engama-30
Ukusebenza Kwemishini
• Amandla okuthamba: 4.9-5.3 g/denier

• Ayimelani nezincibilikisi eziningi eziphilayo (i-benzene, i-acetone)
• Ububanzi bokuzinza kwe-pH: 3-11
• Ukumelana ne-hydrolysis okuphakeme kunezinye i-aramid
Izici Zokuqina
• Ukumelana nokuwohloka kwe-UV: <5% ukulahleka kwamandla ngemva kokuchayeka emahoreni ayi-1000
• Ukumelana nokuguguleka okufana ne-nylon yezinga lezimboni
• Imelana nemijikelezo yokuwasha yezimboni engaphezu kwe-100 ngaphandle kokwehla kokusebenza
▶ Ukusetshenziswa kwe-Nomex Fabric

Izinto zangaphakathi zesitimela esinejubane eliphezulu(izendlalelo zokuvimba umlilo)
Ukusetshenziswa Okukhethekile
Amagilavu ehhavini lasekhishini le-premium(ibanga lezentengiselwano)
Imidiya yokuhlunga yezimboni(ukuhlunga igesi eshisayo)
Indwangu yeseyili esebenza kahle kakhuluyezikebhe zomjaho

Umhlahlandlela Wamandla E-Laser Angcono Kakhulu Okusika Izindwangu
Kule vidiyo, singabona ukuthi izindwangu ezahlukene zokusika nge-laser zidinga amandla ahlukene okusika nge-laser futhi sifunde ukuthi ungazikhetha kanjani amandla e-laser wezinto zakho ukuze uthole ukusikeka okuhlanzekile futhi ugweme amamaki okusha.
0 umphetho wephutha: akusekho ukuphazamiseka kwentambo kanye nemiphetho eqinile, amaphethini ayinkimbinkimbi angakhiwa ngokuchofoza okukodwa. Ukusebenza kahle kabili: ngokushesha okuphindwe kayishumi kunomsebenzi wezandla, ithuluzi elihle lokukhiqiza ngobuningi.
Ungazisika Kanjani Izindwangu Zokugqwala? Umsiki Wekhamera We-Laser Wezingubo Zezemidlalo
Yenzelwe ukusika izindwangu eziphrintiwe, izingubo zezemidlalo, iyunifomu, amajezi, amafulegi anezinyembezi, kanye nezinye izindwangu ezifakwe ngaphansi kwesikhumba.
Njenge-polyester, i-spandex, i-lycra, kanye ne-nylon, lezi zindwangu, ngakolunye uhlangothi, ziza nokusebenza kwe-sublimation okuphezulu, ngakolunye uhlangothi, zinokuhambisana okuhle kakhulu kokusika nge-laser.

▶ Imibuzo Evame Ukubuzwa Kakhulu Nge-Nomex Fabric
Indwangu ye-Nomex iyi-i-meta-aramidi-fibre yokwenziwa eyenziwe yi-I-DuPont(manje sekuyi-Chemours). Yenziwe nge-i-poly-meta-phenylene isophthalamide, uhlobo lwe-polymer engashisi futhi engashisi.
Cha,I-NomexfuthiI-Kevlarazifani, yize zombili zifanaimicu ye-aramidyathuthukiswa yiDuPont futhi yabelana ngezakhiwo ezifanayo.
Yebo,I-Nomex imelana kakhulu nokushisa, okwenza kube ukukhetha okuphezulu kwezicelo lapho ukuvikelwa emazingeni okushisa aphezulu kanye namalangabi kubaluleke kakhulu.
I-Nomex isetshenziswa kabanzi ngenxa yezakhiwo zayo eziwusizo.ukumelana nokushisa okumangalisayo, ukuvikelwa komlilo, kanye nokuqinangenkathi ihlala ilula futhi ikhululekile.
1. Ukumelana Nokushisa Nokushisa Okungalingani
Ayincibilikisi, ayiconsi, noma ayishisikalula—esikhundleni salokho,i-carbonizesuma ibekwe emalangabini, yakha isithiyo esivikelayo.
Imelana namazinga okushisa afinyelela ku-370°C (700°F), okwenza kube yindawo ekahle kakhulu ezindaweni ezivame ukusha.
2. Ukuzicisha Nokuhlangabezana Nezindinganiso Zokuphepha
Ihambisana neI-NFPA 1971(imishini yokucisha umlilo),I-EN ISO 11612(ukuvikelwa kokushisa kwezimboni), kanyeUKUDE 25.853(ukusha kwezindiza).
Kusetshenziswa ezinhlelweni laphoimililo evuthayo, ama-arc kagesi, noma ama-splashes ensimbi encibilikisiweizingozi.
3. Ilula futhi ikhululekile ekugqokeni isikhathi eside
Ngokungafani ne-asbestos enkulu noma i-fiberglass, i-Nomex iyinto eguquguqukayo.kuyaphefumula futhi kuyaguquguquka, okuvumela ukuhambahamba emisebenzini enobungozi obukhulu.
Ngokuvamile kuxutshweI-Kevlarukuze uthole amandla engeziwe nomaukuqeda okumelana namabalaukuze kube lula.
4. Ukuqina Nokumelana Namakhemikhali
Ibamba ngokumeleneamafutha, izinyibilikisi, namakhemikhali ezimbonikungcono kunezindwangu eziningi.
Iyamelanaukukhuhla nokuwasha okuphindaphindiwengaphandle kokulahlekelwa yizakhiwo zokuzivikela.
