Maitiro mashanu e aramid fiber
Mucheka weAramid, kureva Kevlar jira, aramid faibha jira, aramid jira, imhando yejira rine insulation uye nekuchengetedza kupisa.Iine huwandu hwakawanda hwekushandisa muindasitiri uye kuchengetedzwa kwemauto.Iine anotevera maitiro makuru:
1. Yakanaka michina zvimiro Aramid inochinjika polima ine simba rekupwanya rakakwirira kupfuura yakajairwa polyester, donje, naironi, nezvimwewo, ine kurebesa kukuru, kunzwa kwakapfava uye kutenderera kwakanaka, uye inogona Kugadzirwa kuita shinda dzakasiana dzekuramba uye kureba.Mumuchina wakajairwa wemachira, mafirita nemafilaments zvinogadzirwa kuita shinda dzakasiyana uye dzakarukwa kuita machira nemachira asina kuruka.Mushure mekupedza, inogona kusangana nezvinodiwa zvezvipfeko zvekudzivirira mundima dzakasiyana.
2.Yakanakisa murazvo retadancy uye kupisa kuramba.Meta-aramids ine inomisa oxygen index (LOI) yakakura kudarika 28 uye saka usarambe uchipisa kana uchisiya murazvo.Iyo murazvo unodzoreredza kuita kweNewstar® meta-aramid kunoenderana neyayo kemikari chimiro, saka iyo isingaperi murazvo inodzoreredza fiber isingaderedze kana kurasikirwa yayo inodzoreredza murazvo nekuda kwekushandisa nguva uye nguva yekugeza.Newstar® meta-aramid ine kugadzikana kwakanaka kwekushisa, inogona kushandiswa nguva dzose pa205 ° C, uye inogona kuramba ichichengetedza simba rakakwirira pane tembiricha yepamusoro inopfuura 205 ° C.Newstar® meta-aramid ine tembiricha yekuora yakanyanya uye hainyauke kana kunyungudika.Inonyunguduka pasi pemamiriro ekushisa kwepamusoro.Carbonization inongotanga patembiricha iri pamusoro pe370°C.
3.Yakagadzika kemikari zvivakwa meta-aramid ine yakanakisa kupikisa kumakemikari mazhinji, inogona kuramba yakawanda-yakanyanya-concentration inorganic acids, uye ine yakanaka alkali kuramba patembiricha yekamuri.
4. Radiation resistance meta-aramid ine yakanakisa radiation kuramba.Semuenzaniso, pasi pekuratidzwa kwenguva refu kune 1.2 × 10-2 w / in2 ultraviolet rays uye 1.72 × 108rads gamma rays, kusimba kwavo kunoramba kusingachinji.
5. Durable meta-aramid inopa yakanakisa kukweshera uye makemikari kuramba.Mushure mekugeza zana, simba rekubvaruka remachira akabatwa neNewstar® meta-aramid achiri kukwanisa kusvika kupfuura 85% yesimba rekutanga.
