Aramid CHIKWANGWANI: zida zofunika ndi ntchito zambiri
Aramid fiber, Zomwe zimadziwikanso kuti aramid, ndi ulusi wopangira womwe umadziwika kwambiri chifukwa cha mphamvu zake zapadera komanso zosagwira kutentha.Zomwe zidapangidwa koyambirira m'ma 1960s, ulusi wa aramid wakhala chisankho chodziwika bwino pamagwiritsidwe osiyanasiyana chifukwa cha kuphatikiza kwawo kwapadera.
Chimodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi ulusi wa aramid ndikupanga zovala zoteteza ndi zida.Chifukwa cha kuchuluka kwake kwamphamvu ndi kulemera kwake komanso kukana kwambiri mabala, ma abrasions ndi ma punctures, ulusi wa aramid ndi wabwino kuti ugwiritse ntchito pazovala zoteteza zipolopolo, zipewa, magolovesi ndi zida zina zodzitetezera.Kuonjezera apo, katundu wake wosamva kutentha amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito muzovala zozimitsa moto ndi kutsekemera kwa mafakitale.
Ntchito ina yofunika yaulusi wa aramidali m'mafakitale oyendetsa ndege ndi magalimoto.Makhalidwe opepuka a Aramid fiber komanso kulimba kwamphamvu kwambiri kumapangitsa kuti ikhale chisankho chabwino kwambiri popanga zida za ndege ndi zakuthambo komanso kupanga matayala ochita bwino kwambiri, ma brake pads ndi zida zina zamagalimoto.Kutentha kwake ndi kukana kwa mankhwala kumapangitsanso kukhala koyenera kugwiritsidwa ntchito popanga ma gaskets, hoses ndi zigawo zina za mafakitale.
Kuphatikiza apo, ulusi wa aramid umagwiritsidwa ntchito kwambiri m'magulu ankhondo ndi chitetezo kupanga zida zankhondo monga magalimoto okhala ndi zida, zipewa ndi zida zankhondo.Amapereka chitetezo chapamwamba ku ma projectiles othamanga kwambiri ndi shrapnel, zomwe zimapangitsa kuti zikhale zofunikira kwambiri poonetsetsa chitetezo cha asilikali.
Kuphatikiza pa kugwiritsa ntchito zida zodzitchinjiriza ndi zakuthambo, ulusi wa aramid amagwiritsidwanso ntchito pantchito yomanga kulimbitsa zomanga za konkriti.Kulimba kwake kwamphamvu komanso kukana kwa dzimbiri kumapangitsa kukhala chisankho chabwino kwambiri pakupanga mlatho, misewu ndi zomangamanga, komwe kulimba komanso moyo wautali ndizofunikira.
Kuphatikiza apo, ulusi wa aramid umagwiritsidwa ntchito popanga zingwe zapamwamba kwambiri komanso zingwe zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza panyanja, m'mphepete mwa nyanja ndi migodi.Zomwe zimakhala zopepuka komanso zamphamvu kwambiri za fiber aramid zimapangitsa kukhala chinthu choyenera kugwiritsa ntchito zomwe sizingatheke ndi zingwe zama waya zachitsulo.
Mitundu ya Aramidperekani zabwino zambiri pazogwiritsa ntchito zosiyanasiyanazi.Mphamvu zake zapadera, kukhazikika, kutentha, kukana kwa mankhwala ndi abrasion kumapangitsa kukhala chinthu chosunthika chomwe chingathe kupirira malo ovuta kwambiri.Kuonjezera apo, chikhalidwe chake chopepuka chimathandizira kugwira ntchito ndikuchepetsa kulemera kwa chinthu chomaliza, ndikupangitsa kukhala chisankho chokondedwa m'mafakitale ambiri.
Ponseponse, mawonekedwe apadera a ulusi wa aramid amawapangitsa kukhala chinthu chofunidwa kwambiri pazogwiritsa ntchito zosiyanasiyana.Kuchokera ku zovala zotetezera ndi zipangizo kupita kumalo opangira ndege ndi magalimoto, ma aramid fibers amakhalabe chinthu chofunika kwambiri poonetsetsa kuti chitetezo, ntchito ndi moyo wautali wazinthu zambiri ndi zomangamanga.Pomwe ukadaulo ukupitilirabe patsogolo, kugwiritsa ntchito ma aramid fibers mwina kupitilira kukula.
