Maburashi omwe amagwiritsidwa ntchito kwambiri popanga burashi m'mafakitale ayenera kukhala ma bristles a nayiloni, chigawo chachikulu cha nayiloni bristles ndi polyamide (Nayiloni), dzina lachingerezi Polyamide (PA mwachidule), ndi liwu lodziwika bwino la utomoni wa thermoplastic wokhala ndi magulu a amide mobwerezabwereza - [NHCO ]- pa tcheni chachikulu cha molekyulu.Zimaphatikizapo aliphatic PA, aliphatic-aromatic PA ndi onunkhira PA, omwe pali mitundu yambiri, mavoti akuluakulu opangidwa ndi ntchito zosiyanasiyana, ndipo dzina lake limatsimikiziridwa ndi chiwerengero cha maatomu a carbon mu monoma yopangira.

Mitundu yayikulu ya nayiloni ndi nayiloni 6 ndi nayiloni 66, zomwe ndizopambana kwambiri.Pali mitundu yambiri yosinthidwa ya nayiloni, monga nayiloni yolimbitsa, nayiloni ya monomer cast (MC nayiloni), nayiloni yokhazikika (RIM) nayiloni, nayiloni yonunkhira, nayiloni yowonekera, nayiloni yolimba kwambiri (yolimba kwambiri), nayiloni yopangidwa ndi electroplated, magetsi. nayiloni conductive, nayiloni retardant lawi, nayiloni zikuphatikiza ndi ma polima ena ndi aloyi, etc. kukumana osiyana Iwo ankagwiritsa ntchito m'malo mwa zipangizo zachikhalidwe monga zitsulo ndi matabwa, ndi zipangizo structural mitundu yonse.

Nayiloni ndiye pulasitiki wofunikira kwambiri wauinjiniya, wokhala ndi voliyumu yapamwamba kwambiri pakati pa mapulasitiki asanu apamwamba kwambiri aukadaulo.Nayiloni imakhala ndi mphamvu zamakina apamwamba, malo ochepetsetsa kwambiri, kukana kutentha, kugundana kochepa, kukana kwa abrasion, kudzipaka mafuta, kutulutsa mawu, kutulutsa mawu, kukana mafuta, kukana kufooka kwa asidi, kukana kwa alkali ndi kukana zosungunulira, kutsekemera kwamagetsi, kudzikonda. -zozimitsa, zosakhala ndi poizoni, zosanunkhiza, zolimbana ndi nyengo yabwino komanso kusataya utoto.Choyipa chake ndikuti kuyamwa kwamadzi ndi kwakukulu, komwe kumakhudza kukhazikika kwa mawonekedwe ndi mphamvu zamagetsi.Kulimbitsa kwa fiber kumatha kuchepetsa kuyamwa kwamadzi kwa utomoni kuti chitha kugwira ntchito pa kutentha kwambiri komanso chinyezi chambiri.Nayiloni imalumikizana bwino kwambiri ndi ulusi wagalasi.

Nylon 66 imakhala yolimba kwambiri komanso yolimba, koma yolimba kwambiri.Ma nayiloni osiyanasiyana amalamulidwa ndi kulimba: PA66＜PA66/6＜PA6＜PA610＜PA11＜PA12 Kupsa kwa nayiloni ndi mlingo wa UL94v-2, mlozera wa oxygen ndi 24-28, kutentha kwa nayiloni ndi>299℃, kuyaka kudzachitika pa 449 ~ 499 ℃.Kusungunuka kwa nayiloni ndikwabwino, kotero makulidwe a khoma la mankhwalawa amatha kukhala ochepa ngati 1mm.
