Mumakore achangopfuura, hunyanzvi hwekugadzira maindasitiri muChina hwakaramba huchivandudzwa.Muhuwandu huri kuwedzera hweruzivo, kusimukira kweindasitiri yetambo dzearamid muChina kwagara kuri kutarisisa kwedu.Zvese zviri zviviri zvishandiso zvedu zvemachira nemichina yedu yemachira zvakafambira mberi zvikuru.Unogona kufunga kuti indasitiri yemachira inongokanganisa zvigadzirwa, uye isu hatina kana zvipfeko.Kuonekwa kwe tekinoroji yematekinoroji hakungokanganisa kupfeka kwembatya dzedu, asiwo indasitiri yedu.Ngatitarisei maitiro etambo yearamid.
Yakanaka michina zvivakwa, inochinjika polymer pakati pearamid tambo uye faibha, inopwanya simba rakakwirira kupfuura yakajairwa polyester, donje, naironi, nezvimwewo, kureba, kupfava uye kwakanaka spinnability, iyo inogona kuburitsa hukuru hwakasiyana, hupfupi fiber dimensions uye filament kureba.Mune shinda dzakasiyana-siyana, machira emachira anoverengera machira uye asina-akarukwa machira, uye mushure mekupedza, anogona kusangana nezvinodiwa zvezvipfeko zvekudzivirira munzvimbo dzakasiyana.Aramid tambo ine yakanakisa murazvo retardancy, iyo inomisikidza okisijeni index yearyl oxide yakakura kupfuura 28, uye haizoramba ichipisa kana ichinge yabva mumurazvo.
Iyo flame retardant pfuma yearamid fiber tambo inotarwa nechimiro chayo chemakemikari.Iyo yakagadzika kemikari zvimiro zvearamid faibha zvine zvimiro zvakanaka, uye mazhinji makemikari anoshingirira kune yakawanda inorganic acid yekumisikidza uye alkaline tembiricha.Anti-radiation Lun ine yakanakisa kupikisa kwemwaranzi, uye simba rayo rinoramba risina kushanduka mushure menguva refu yekuvhenekera.
Sezvo isu tichiziva, nekuda kweakanakisa emuchina zvivakwa, kupisa kupisa, kusadzivirirwa kwekuora uye kudzoreredza kwemurazvo wemucheka wetambo wearamid, yakashandiswa zvakanyanya muminda yemotokari uye nendege.Isu tinokwanisa zvakare kubata aramid core yarn nenzira dzemuviri kana kemikari pamusoro pekurapa, uye kuwedzera kushata kwearamid fiber pamusoro kana imwe nhamba yemapoka anoshanda pane iyo fiber pamusoro, nekudaro kuvandudza zvakanyanya kusimba kwekubatanidza pakati pearamid tambo uye matrix.Nokudaro, kushandiswa kwemucheka wearamid kuchave kwakanyanya.
