PA66
PA66 ndi zinthu zosunthika zomwe zimagwiritsidwa ntchito popanga zinthu zosiyanasiyana monga bristles, maburashi amizere, maburashi otsukira, maburashi akumafakitale, ndi mawaya a brush.Polima iyi yokhazikika komanso yosinthika imagwira ntchito yofunika kwambiri popanga zida zaukhondo wapakamwa, kuphatikiza misuwachi, komanso kupanga maburashi omwe amagwiritsidwa ntchito poyeretsa ntchito m'mafakitale osiyanasiyana.
PA66, yomwe imadziwikanso kuti nayiloni 66, imakhala ndi mawonekedwe ofanana ndi PA (polyamide).Komabe, nthawi zambiri imakhala ndi mayamwidwe otsika pang'ono komanso kutentha kwambiri poyerekeza ndi PA.Zinthu zowonjezerazi zimapangitsa PA66 kukhala chisankho chokondedwa pamapulogalamu omwe amafunikira kukhazikika komanso kukhazikika kwamafuta.Ngakhale zabwino zake, kugwiritsa ntchito PA66 kungaphatikizepo mtengo wokwera pang'ono poyerekeza ndi PA6 chifukwa cha magwiridwe ake apamwamba.
Pankhani yopanga burashi yamakampani, waya wa nayiloni ndi chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri.Waya wa nayiloni wa burashi, wopangidwa makamaka ndi polyamide, yomwe imadziwika kuti nayiloni, ndi mtundu wa utomoni wa thermoplastic.Polyamide, yofupikitsidwa ngati PA, imakhala ndi tcheni chachikulu cha molekyulu chokhala ndi magawo obwereza a gulu la amide - [NHCO]-.Zimaphatikizapo mitundu yosiyanasiyana monga aliphatic PA, aliphatic-aromatic PA, ndi PA onunkhira.Mwa izi, aliphatic PA ndiyomwe imapangidwa ndikugwiritsidwa ntchito kwambiri, ndipo dzina lake limatsimikiziridwa ndi kuchuluka kwa maatomu a kaboni pakuphatikizika kwa monoma inayake.
Nayiloni, yomwe imadziwikanso kuti polyamide, imabwera m'njira zosiyanasiyana, ndipo nayiloni 6 ndi nayiloni 66 ndiye mitundu yoyambirira.Mitundu iwiriyi ya nayiloni imakhala ndi mphamvu zonse pakusintha kwa nayiloni, zomwe zimapereka zosankha zambiri zoti musinthe.Zina mwa mitundu ya nayiloni yosinthidwa yomwe imagwiritsidwa ntchito kwambiri ndi nayiloni yolimba, nayiloni yolimba, monomer casting nayiloni (MC nayiloni), nayiloni yochitira jekeseni (RIM) nayiloni, nayiloni yonunkhira, nayiloni yowonekera, nayiloni yamphamvu kwambiri (yolimba kwambiri), nayiloni ya electroplating, nayiloni yoyendetsa, nayiloni yosagwiritsa ntchito malawi, ndi zitsulo za nayiloni.Mapangidwe apadera a nayiloniwa amakwaniritsa zofunikira zosiyanasiyana, kuyambira kumphamvu ndi kulimba mpaka kuzinthu zinazake zogwirira ntchito monga kuwonekera, kuwongolera, ndi kukana moto.
Nayiloni ndi zotuluka zake zimakhala zosinthika m'malo mwa zinthu zakale monga zitsulo ndi matabwa.Amapeza ntchito zofala m'mafakitale osiyanasiyana, zomwe zimagwiritsidwa ntchito m'malo mwa zitsulo m'makina, matabwa pomanga, ndi zida zina zomangira.Kusinthasintha komanso kusinthasintha kwa nayiloni kumapangitsa kuti ikhale yofunika kwambiri pakupanga kwamakono, zomwe zimathandizira kupita patsogolo kwa kapangidwe kazinthu, magwiridwe antchito, komanso kukhazikika.
