PA66
PA66 chinhu chakasiyana-siyana chinowanzo shandiswa mukugadzira zvinhu zvakasiyana senge bhurasho remazino, mabhurashi emitsetse, mabhurashi ekuchenesa, mabhurashi eindasitiri, uye waya yebhurashi.Iyi inogara uye inochinjika polymer inoita basa rakakosha mukugadzira mabristle emidziyo yehutsanana hwemukanwa, kusanganisira bhurasho remazino, pamwe nekugadzira mabhurashi anoshandiswa mukuchenesa maapplication mumaindasitiri akasiyana.
PA66, inozivikanwawo senaironi 66, inoratidza maitiro akafanana nePA (polyamide).Nekudaro, iyo inowanzo ine yakadzikira mvura yekunyudza mazinga uye yakakwirira tembiricha kuramba kana ichienzaniswa nePA.Izvi zvakagadziridzwa zvivakwa zvinoita kuti PA66 ive sarudzo yakasarudzika yemashandisirwo anoda kusimba uye kugadzikana kwemafuta.Kunyangwe zvakanakira, kushandiswa kwePA66 kunogona kusanganisira mutengo wakakwira zvishoma uchienzaniswa nePA6 nekuda kwekuita kwayo kwepamusoro.
Kana zvasvika pakugadzirwa kwebhurashi reindasitiri, waya yenylon brashi ndechimwe chezvinhu zvinonyanya kushandiswa.Nylon brashi waya, inoumbwa zvakanyanya ne polyamide, inowanzo zivikanwa senaironi, imhando ye thermoplastic resin.Polyamide, yakapfupikiswa sePA, inoratidzira molecular main cheni ine kudzokorora zvikamu zveboka reamide - [NHCO]-.Inosanganisira marudzi akasiyana senge aliphatic PA, aliphatic-aromatic PA, uye inonhuhwirira PA.Pakati peizvi, aliphatic PA ndiyo inonyanya kugadzirwa uye kushandiswa, ine zita rayo rinotemerwa nehuwandu hweatomu kabhoni mukubatanidzwa kweiyo monoma chaiyo.
Nylon, inozivikanwawo sepolyamide, inouya nenzira dzakasiyana, naironi 6 uye naironi 66 iri iyo mhando dzekutanga.Idzi mhando mbiri dzenylon dzinobata hutongi hwakakwana munzvimbo yenylon shanduko, ichipa plethora yesarudzo dzekugadzirisa.Mamwe emhando dzenaironi dzakashandiswa zvakanyanya dzinosanganisira yakasimbiswa naironi, monomer casting nylon (MC nylon), reaction jekiseni molding (RIM) nylon, inonhuhwirira nylon, transparent nylon, high-impact (super-tough) nylon, electroplating nylon, conductive nylon, Naironi isingadzore murazvo, uye zviwanikwa zvenaironi.Aya magadzirirwo enylon ane hunyanzvi anoenderana nezvinodiwa zvakasiyana, kubva pakuwedzerwa simba uye kusimba kune chaiyo inoshanda zvinhu zvakaita sekujeka, conductivity, uye kuramba kwemoto.
Nylon uye zvinobva mairi zvinoshanda sedzimwe nzira dzakasiyana kune dzechinyakare zvinhu zvakaita sesimbi nehuni.Vanowana kushandiswa kwakapararira mumaindasitiri akasiyana-siyana, kushanda sechinotsiva simbi muzvikamu zvemichina, matanda mukuvaka, uye zvimwe zvinhu zvemagadzirirwo.Iko kuchinjika uye kuita kwakasiyana-siyana kwenylon kunoita kuti ive yakakosha mumagadzirirwo emazuva ano ekugadzira, zvichibatsira mukufambira mberi mukugadzirwa kwechigadzirwa, kuita, uye kuenderera mberi.
