Bhuma ndichipanga chothandiza m'mbiri ya anthu. Kuyambira kale pamene anthu anagwiritsa ntchito mitengo yopukutira ndi miyala yolumikizidwa kuti iloke mitsinje yamadzi ndi mitsinje, kuti igwiritsidwe ntchito milatho ngakhale milathoyo, ngakhale zingwe zokhala ndi zingwe, chisinthiko chakhala chodabwitsa. Kutsegulidwa kwaposachedwa kwa Hong Kong-zhuha-Macao Bridge kumalemba zinthu zofunika kwambiri m'mbiri ya milatho. Mu gawo lamakono la Bridgration, kuwonjezera kugwiritsa ntchito ma conticrete olimbikitsidwa konkriti, zida zachitsulo, makamaka ma aluminiyamu olosera, akhala akusankha bwino kwambiri chifukwa cha zabwino zawo.
Mu 1933, a Aloy a Aloy Strid Reck adagwiritsidwa ntchito pa mlatho ukukwera mtsinje ku Pittsburgh ku United States. Zoposa zaka khumi, mu 1949, Canada idamaliza kuzengereza konsekonse kudutsa mtsinje wa Saguenay ku Quebec, ndi mpata umodzi wofikira 88.4. Mlatho uwu unali mawonekedwe oyamba padziko lonse lapansi. Mlathowo unali ndi zojambula pafupifupi 15 mita kutalika ndi ziwiri za magalimoto. Inagwiritsa ntchito 2014-t6 aluminium losoy ndipo anali ndi kulemera kwathunthu kwa matani 163. Poyerekeza ndi mlatho wachitsulo choyambirira, chimachepetsa thupi pofika pafupifupi 56%.
Kuyambira pamenepo, zomwe zimachitika a aluminiyamu alloy zojambula zazikazi zakhala zosatheka. Pakati pa 1949 ndi 1985, United Kingdom idapanga pafupifupi 35 aluminium ma haldidgeramin, pomwe Germany idamanga mabatani 20 ndi 1970. Kumanga mabatani ambiri a aluminiyamu.
Poyerekeza ndi zitsulo, zitsulo za aloy zimakhala ndi kachulukidwe kakang'ono kwambiri, ndikuwapangitsa kukhala opepuka kwambiri, pokhapokha ngati ndi kulemera kwamitundu imodzi. Komabe, ali ndi mphamvu zofanana ndi zitsulo. Kuphatikiza apo, aluminiyamu alumusys akuwonetsa bwino kwambiri komanso kukana kuwononga pomwe amakhala ndi ndalama zotsika. Zotsatira zake, apeza ntchito yambiri mu Britran yamakono.
China yachititsa chidwi mu mlatho womanga nawo bwino. Bridge ya Zhaozhou, ataimirira kwa zaka zopitilira 1500, ndi imodzi mwazomwe zimakwaniritsa chikhomo cha Chidule cha Brid Bridge. M'nthawi yamakono, mothandizidwa ndi Soviet Union wakale wa Soviet, ku China adapanganso milatho yachitsulo, kuphatikizapo milatho yamtsinje ya Yangtze ku nanzeng ndi Wuhan, komanso mlatho wa Peangl ku Guangzhou. Komabe, kugwiritsa ntchito aluminium alloy mabatani ku China kumawoneka kuti ndi ochepa. Aluminiyamu woyamba wa aluminiyamu urticrami ya ku China inali mlatho paulendo wa quingchuu, omangidwa mu 2007. Mlangizi uwu adapangidwa ndikuikidwa ndi akatswiri ojambula ku Germany. M'chaka chomwecho, mlatho wa oyenda ku Xujai, Shanghai, adapangidwa kwathunthu ndikupanga magwiridwe antchito a aluminium a aluminium. Amagwiritsa ntchito 6061-t6 aluminium a aluminiyamu ndipo, ngakhale kuti amadzipanga okha matani 15, amatha kugwirizira katundu wa matani 50.
M'tsogolomu, aluminiyamu milatho ali ndi chiyembekezo chachikulu ku China pazifukwa zingapo:
Ntchito yomanga njanji 1 ikuyenda bwino, makamaka m'magulu ovuta a madera akumadzulo omwe ali ndi zigwa ndi mitsinje yambiri. Aluminium alloy milatho, chifukwa chopumira komanso katundu wawo wowunikira, akuyembekezeka kukhala ndi msika wofunikira.
Zinthu ziwiri zachitsulo zimakonda dzimbiri ndikukhala ndi magwiridwe antchito otsika. Kugwedeza kwa chitsulo kumakhudza kwambiri kukhazikika kwa mlatho, zomwe zimapangitsa kuti zikhale zowononga ndalama komanso zoopsa. Mosiyana ndi izi, zinthu za alminiyamu zimatsutsana kwambiri ndi kutumphuka kwakukulu ndikuchita bwino, ndikuwapangitsa kukhala oyenera nyengo zosiyanasiyana ndikuonetsetsa kulimba kwanthawi yayitali. Pomwe aluminium aluya amatha kukhala ndi ndalama zomangamanga kwambiri, ndalama zokwanira zokwanira zimatha kuthandiza kuchepetsa kusiyana kwa mtengo.
3 Kafukufuku pa mapanelo a aluminiyamu a Brium, onse apadziko lonse lapansi komanso padziko lonse lapansi, amapangidwa bwino, ndipo zinthuzi zimagwiritsidwa ntchito kwambiri. Kupita patsogolo kwa kafukufuku wa zinthu kumapereka chitsimikizo chaukadaulo kuti chikulitse zowongolera zatsopano zomwe zimakwaniritsa zofunikira zina. Opanga aluminium aku China, kuphatikiza zimphona zokhalamo ngati Lianang Zhongwang, pang'onopang'ono asintha mawonekedwe awo ku Aluminium a aluminiyamu a aluminiyamu.
4 Kukonzekera kwa Urban Montray Kupanga mizinda yayikulu ya China kumapangitsa zingwe zoyeserera kuchokera pamwamba. Chifukwa cha maubwino awo ofunika, zimawonekeratu kuti aluminiyamu a aluminian oyenda ndi mizere yayikulu idzapangidwa ndikugwiritsidwa ntchito mtsogolo.
Zosinthidwa ndi Meying kuchokera ku Mat Aluminium
