Kuiswa kwe polyamid pa6
Polyamide, inonzi polyamide pa kwenguva pfupi, inowanzo zivikanwa senaironi.Iyo imhando yecrystalline thermoplastic purasitiki yakaumbwa nepolymerization yemabhinari amines uye diacid kana lactam.Kune akawanda marudzi ePA, zvichienderana nehuwandu hwekabhoni maatomu mune monomer inobatanidzwa mune polymerization reaction, uye akasiyana marudzi ePA ane akasiyana maitiro anogona kuumbwa, senge PA6, PA66, PA612, PA1010, PA11, PA12, PA46 , PA9, PA1212, etc. PA6 uye PA66 ndiyo inonyanya kushandiswa, inoverengera 90% yehuwandu hwekugadzirwa.
Izvo zvakajairika zve polyamid pa6
Polyamid pa6 ine polarity, isiri-chepfu, isinganakidze uye iri nyore kuve neruvara; Crystalline type (50 kusvika 60%), translucent milky chena kana light yellow granule; Newtonian fluid (Newtonian fluid inoreva zvinwiwa apo kushushikana kunoenzana ne the strain rate); Density: 1.02 kusvika 1.20g/cm³;Kunyura kwemvura yakakwira, hydrolysis reaction ichaitika pa230 degrees Celsius;Kunyura kwemvura PA46 > PA6 > PA66 > PA1010 > PA11 > PA12 > PA1212;Hombe kuderera kwekuumbwa.PP, PE > PA > PS, ABS.Pakati pechivhariso pfuma uye yakasimba chipingamupinyi kumhepo.
Iyo mechanic properties ye polyamid pa6
Iyo mechanic properties ye polyamid pa6 inowanzo enderana necrystallinity: Iyo yakakwirira iyo crystallinity, iyo yakakwirira simba uye yakasimba kusimba.Mukutaura kwesimba, PC> PA66> PA6> POM> ABS.Simba rinonyanya kukanganiswa ne hygroscopicity, iyo yakakwirira yekushisa, iyo yakakwirira ye hygroscopicity, inoderedza simba rekugadzirisa uye zvimwe zvinhu.
Iko kuoma kwemaitiro kunokanganisa zvakanyanya neiyo hygroscopic performance.Nekuwedzera kwekushisa, kunyura kwemvura kunowedzera uye kuoma kunowedzera.(Kazhinji, kuomarara kwakashata munzvimbo yakaoma uye yakaderera tembiricha, uye inogona kuve nekunetsekana kutsemuka nezvigadzirwa zvesimbi uye brittle kutyoka pa 0 ℃.
Polyamid pa6 ine yakanaka self lubricity uye yakanaka kupfeka kuramba.
Kupokana kwakanakisa kumafuta, semuenzaniso.peturu.
Simba rekuneta rakakwira, kazhinji 20% kusvika 30% yesimba rekusimba.Simba rekuneta kwePA6 nePA66 rinogona kusvika pa22MPa, yechipiri chete kune POM (35MPa) uye yakakwirira kupfuura PC (10-14MPa).Kutevedzana maererano nekuneta simba: POM> PBT, PET> PA66> PA6> PC> PSF> PP.
Kuoma kwepamusoro, PA66: 108 kusvika ku120HRR;PA6120HRR.
Murombo Creep kuramba: Zvirinani pane PP uye PE, uye yakaipisisa kupfuura ABS nePOM.
Kusagadzikana kwekushushikana kwekupokana: Kubata kana humidification kurapwa kunofanirwa kuitwa mushure mekugadzirisa zvigadzirwa.
