Kugwiritsa ntchito nsalu za aramid fiber muzinthu zopanda zipolopolo

Aramid fiberndi ulusi wopangira kwambiri, wokhala ndi mphamvu zochulukirapo, modulus wapamwamba, kukana kutentha kwambiri, kukana kwa asidi ndi alkali, kupepuka, ndi zina zabwino kwambiri. Mphamvu zake zimatha kukhala nthawi 5-6 kuposa waya wachitsulo, modulus ndi 2-3 nthawi ya waya wachitsulo kapena ulusi wagalasi, kulimba ndi 2 kuwirikiza kwa waya wachitsulo, ndipo kulemera kwake ndi 1/5 kokha kwa waya wachitsulo. Pa kutentha kwakukulu kwa 560 ℃, ulusi wa aramid ukhoza kukhala wosasunthika, osawola, komanso osasungunuka. Kuphatikiza apo, ili ndi zotsekemera zabwino komanso zotsutsana ndi ukalamba, komanso moyo wautali wautumiki. Pakali pano, zida zodziwika bwino zoteteza zipolopolo (monga zovala zoteteza zipolopolo, ndi zipewa zoteteza zipolopolo) zimakonda kugwiritsa ntchito.nsalu za aramid fiber. Mwa iwo, nsalu yotsika yokoka ya aramid fiber plain ndi imodzi mwazinthu zofunika kwambiri pantchito yoletsa zipolopolo. Poyerekeza ndi malaya amkati a nayiloni achikhalidwe ndi zipewa zachitsulo, malaya amkati otetezedwa ndi zipolopolo ndi zipewa zokhala ndi ulusi wowonjezera wa aramid sizongocheperako komanso zopepuka komanso 40% zogwira mtima kwambiri polimbana ndi zipolopolo.

Mfundo yogwirira ntchito ya zovala zoteteza zipolopolo zimatha kumveka motere: chipolopolo chikagunda pansalu ya vest, mafunde ogwedezeka ndi mafunde amapangidwa mozungulira pozungulira. Mafunde amenewa kudzera mu kufalitsa mofulumira ndi kufalikira kwa CHIKWANGWANI, akhoza kusuntha mu ulusi wambirimbiri, ndiyeno m'dera lalikulu kuti atenge mphamvu za kugwedeza kwamphamvu. Ndiko kuyamwa kwamphamvu kotereku komwe kumachepetsa mphamvu ya zipolopolo mthupi la munthu, potero kuzindikira chitetezo cha ma vests oteteza zipolopolo.

Bulletproof ndi magwiridwe ake abwino kwambiri

Pakatikati pa ma vests oteteza zipolopolo pamakhala zida zolimba kwambiri zomwe amagwiritsa ntchito, pomwe ulusi wa para-aramid, womwe umadziwikanso kuti para-aromatic polyamide fibers, ndi chinthu cholemekezedwa kwambiri choteteza zipolopolo. Kapangidwe kake kakang'ono kwambiri ka mankhwala kumapangitsa kuti unyolo wa mamolekyu ukhale wosasunthika kwambiri, ndikupangitsa kuti ikhale yosiyana kwambiri ndi ma polima osinthika osinthika potengera kusungunuka, ma rheological properties, komanso kukonza.

Ulusi wa Para-aramid umadziwika ndi mawonekedwe ake abwino kwambiri akuthupi komanso amakina, kuphatikiza kulimba kwambiri, modulus yayikulu, komanso kupepuka. Mphamvu zawo zenizeni ndizokwera kasanu mpaka kasanu ndi kamodzi kuposa waya wachitsulo wamba, ndipo modulus yawo yeniyeni imaposa waya wachitsulo ndi ziwiri kapena zitatu. Kuonjezera apo, ulusiwo umasonyeza zinthu zabwino kwambiri zotentha, zokhala ndi kutentha kwapamwamba, kuwonjezereka kochepa, ndi kutsika kwa kutentha, ndipo siziwotcha kapena kusungunuka. Ulusi wa Para-aramid umadziwikanso kuti "zingwe zoteteza zipolopolo" chifukwa cha kutchinjiriza bwino, kukana dzimbiri, komanso kusakalamba.

Mapulogalamu ndi Zoyembekeza za Para-Aramid Fiber

Para-aramid fiber, chinthu chofunikira kwambiri pachitetezo chankhondo komanso chankhondo, chimagwiritsidwa ntchito padziko lonse lapansi. Malinga ndi ziwerengero, gawo la aramid mu ulusi woteteza ku US ndi wopitilira 50% ndi 10% ku Japan. Mawonekedwe ake opepuka amapanga zovala zoteteza zipolopolo za aramid ndi zipewa, zomwe zimatha kupititsa patsogolo kuyankha mwachangu kwa asitikali. Kuphatikiza apo, para-aramid imagwiritsidwa ntchito kwambiri pamagalimoto, matelefoni, mlengalenga, komanso masewera akunja chifukwa chakuchita bwino.
