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 kunyura kwemvura mwero uye yakakwirira tembiricha kuramba uchienzaniswa nePA.Izvi zvakagadziridzwa zvivakwa zvinoita kuti PA66 ive sarudzo inosarudzika kune maapplication 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-siyana 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 monomer chaiyo.
Nylon, inozivikanwawo sepolyamide, inouya nenzira dzakasiyana, naironi 6 uye naironi 66 iri iyo mhando dzekutanga.Aya marudzi maviri enylon ane hutongi hwakakwana munzvimbo yenylon shanduko, ichipa plethora yesarudzo dzekugadzirisa.Mamwe emhando dzenylon 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 inodzora murazvo, uye alloys alloys.Aya maumbirwo enaironi ane hunyanzvi anoenderana nezvinodiwa zvakasiyana, kubva pakuwedzerwa simba uye kusimba kune chaiyo inoshanda zvinhu zvakaita sekujeka, conductivity, uye kuramba moto.
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 kusimba.
