Aramid Fiber

Aramid CHIKWANGWANI amatchedwa polybenzoylenediamine, ndi mpweya CHIKWANGWANI, kopitilira muyeso-mkulu molekyulu kulemera polyethylene CHIKWANGWANI ndi atatu padziko lonse mkulu-ntchito CHIKWANGWANI, ndi kachulukidwe kakang'ono, mphamvu mkulu, modulus mkulu, kutentha kukana, dzimbiri kukana, kutchinjiriza, chimagwiritsidwa ntchito mu zankhondo, zakuthambo, zida zamagetsi, zoyendera, zomangamanga, zamankhwala ndi zina.Chingwe cha Aramid ndi chopangidwa ndi fungo lonunkhira bwino la polyamide, chomwe chimapangidwa ndi polima liniya (osachepera 85% ya chomangira cha amide chimalumikizidwa mwachindunji ndi mphete ziwiri zonunkhiritsa) zopangidwa ndi mphete ya amide yolumikizira yonunkhira (Ar-CONH-Ar).Unyolo waukulu umapangidwa ndi mphete yonunkhira komanso chomangira cha amide, ndipo mawonekedwe a mphete onunkhira amakhala olimba.Unyolo wa polima umatambasulidwa kuti ukhale ngati ndodo.

Nthawi yomweyo, mawonekedwe amtundu wa unyolo wa ma molekyulu amapangitsa kuti ma aramid fiber space agwiritsidwe ntchito ndi apamwamba, kotero kuti voliyumu ya unit imatha kukhala ndi ma polima ambiri, motero mphamvuyo ndi yayikulu.Mosiyana ndi maunyolo osinthika a ma polima a molekyulu, unyolo waukulu wa para-aramid fiber umapangidwa makamaka ndi ndodo ngati mamolekyu opangidwa ndi mphete ya benzene.Chifukwa cha kukhalapo kwa mphete yayikulu ya benzene, gawo la unyolo wa ma molekyulu ndizovuta kuzungulira mkati, motero limapereka mawonekedwe olimba.
