Ma wheelchairs amagetsi, monga chida chatsopano chothandizira kuyenda pang'onopang'ono, pang'onopang'ono anthu ambiri okalamba ndi olumala azindikira. Kodi tingagule bwanjimpando wa olumala wamagetsi wotsika mtengo?

Monga munthu amene wakhala akugwira ntchito m'makampani kwa zaka zoposa khumi, ndikufuna kukuthandizani mwachidule kuthetsa vutoli kuchokera mbali zingapo. Choyamba chomwe tiyenera kudziwa ndichakuti gulu lililonse ndi momwe zinthu zilili komanso momwe wogwiritsa ntchito amagwiritsira ntchito zinthuzo zimasiyana, zomwe zimapangitsanso kuti zinthu zomwe zagulidwa zisiyane.

Zipangizo zodziwika bwino zimagawidwa makamaka mu chitsulo cha kaboni, aloyi a aluminiyamu, aloyi a aluminiyamu a aerospace titanium ndi aloyi a magnesium, ndi ulusi wa kaboni.

1. Chitsulo cha kaboni.

Chitsulo cha kaboni chimagwiritsidwa ntchito makamaka m'magudumu akuluakulu ndipo mitundu ina yopangidwa ndi mafakitale ang'onoang'ono, magudumu akuluakulu amagwiritsa ntchito chimango chachitsulo kuti awonjezere kuuma kwa thupi ndi kukhazikika kwa kuyendetsa, mwachitsanzo, magalimoto akuluakulu ambiri ali ndi mafelemu achitsulo ndipo magalimoto ang'onoang'ono amatha kugwiritsa ntchito aluminiyamu ndi chifukwa chomwecho, mafakitale ang'onoang'ono amapanga magudumu akuluakulu pogwiritsa ntchito mafelemu achitsulo chifukwa mtundu uwu wa njira yokonzera ndi kuwotcherera ndi wochepa, mtengo wake nawonso ndi wocheperako. Chifukwa chomwe mafakitale ang'onoang'ono amagwiritsa ntchito mafelemu achitsulo ndichakuti amafunikira ntchito yochepa komanso kuwotcherera ndipo ndi otsika mtengo.

2. Aluminiyamu ndi titaniyamu-aluminium alloy

Aluminiyamu ndi aluminiyamu ya titaniyamu, zinthu ziwirizi zimagwiritsa ntchito kwambiri mipando yamagetsi ya olumala, ndi mitundu iwiri yosiyana ya aluminiyamu ya 7001 ndi 7003, kutanthauza aluminiyamu yokhala ndi zinthu zina zosiyanasiyana zosakanikirana, makhalidwe awo ofanana ndi otsika kwambiri komanso amphamvu kwambiri, kukana bwino pulasitiki komanso kukana dzimbiri, kunena mwachidule ndi yopepuka komanso yamphamvu komanso yokonza bwino, pomwe aloyi ya titaniyamu ndi Amadziwikanso kuti aloyi ya titaniyamu-aluminium chifukwa cha mphamvu zake komanso kukana dzimbiri. Popeza malo osungunuka a titaniyamu ndi okwera kwambiri, kufika madigiri 1942, omwe ndi madigiri oposa 900 kuposa a golide, njira yokonza ndi kuwotcherera ndi yovuta kwambiri mwachibadwa ndipo singapangidwe ndi fakitale yaying'ono yokonza, kotero mipando ya olumala yopangidwa ndi aloyi ya titaniyamu-aluminium ndi yokwera mtengo kwambiri. Yoyamba ndi yoyenera kugwiritsidwa ntchito kawirikawiri komanso mikhalidwe yabwino yamisewu ndi yoyendetsa, pomwe ogwiritsa ntchito omwe amagwiritsa ntchito pafupipafupi, nthawi zambiri amafunika kunyamula, ndipo nthawi zambiri amayendetsa m'maenje ndi misewu yodzaza ndi mikwingwirima amatha kusankha njinga ya olumala yopangidwa ndi aloyi ya titaniyamu-aluminium.

3. Aloyi wa magnesium

Magnesium alloy imachokera ku magnesium kuti igwirizane ndi zinthu zina za alloy. Makhalidwe ake ndi awa: kukhuthala pang'ono, mphamvu yayikulu, kusinthasintha kwakukulu, kutentha bwino, kuyamwa bwino kwa shock, kuthekera kopirira katundu wovuta kuposa alloy ya aluminiyamu, yomwe imagwiritsidwa ntchito kwambiri ndi magnesium-aluminium alloy. Magnesium ndi yopepuka kwambiri mwa zitsulo zothandiza, yokhala ndi mphamvu yokoka pafupifupi magawo awiri mwa atatu kuposa aluminiyamu ndi kotala limodzi la chitsulo, komanso kugwiritsa ntchito magnesium pa mafelemu a olumalacholinga chake ndi kupeza "kupepuka" kowonjezereka pogwiritsa ntchito aluminiyamu.
