nkhani

Ndi chitukuko cha nthawi, ma helikopita ambiri amawonekera m'moyo. Ma helikopita akhala akugwiritsidwa ntchito populumutsa anthu kuchipatala komanso poyendera alendo. Kuti akwaniritse zofunikira ndi kuvomerezedwa, ma helikopita ambiri amafunika kuyikidwa. Maukonde Otetezera, zomwe zimateteza ma helikopita ndi anthu. Nkhaniyi ikubweretsa aluminiyamu yathu Chitetezo Chokwanira.

Popeza ndi zipangizo zomangira zitseko ndi mawindo, ma hinge okhazikika amafunika ndi banja lililonse, lomwe lili ndi msika waukulu padziko lonse lapansi ndipo ndi chowonjezera chomwe chimakonda kwambiri panyumba. Poyerekeza ndi hinge yachikhalidwe, magwiridwe ake ndi apamwamba kuposa hinge yachikhalidwe. Tiyeni tiphunzire zambiri za icho.

Nthawi zikupita patsogolo, ndipo chilichonse chikupita patsogolo. Hinge, monga zipangizo zokonzera nyumba, ndiye zida za chitseko. Amagwiritsidwa ntchito kwambiri kulikonse padziko lapansi, bola ngati pali chitseko, padzakhala ma hinge. Pachitukukochi, anthu ena amapeza kuti hinge ikagwiritsidwa ntchito pachitseko chachikulu, imasweka ndikuwonongeka, ndipo ngakhale chitseko chachikulu chimagwa mwachindunji, zomwe zimapangitsa kuti anthu ambiri atayike. Pamene aliyense anakhumudwa kwambiri, mtundu watsopano wa zida za chitseko unawonekera, womwe unkatchedwa hinge yokhazikika. Maonekedwe ake adzathetsa vuto lomwe lakhala likuvutitsa kale. Kodi chowonadi ndi chiyani? Tikunena m'nkhaniyi.

Chotchingira chokhazikika chokhazikika, Chotchingira chokhazikika chokhazikika chobisika, chotchingira chitseko chobisika, chotchingira chokhazikika cha aluminiyamu. Chili ndi mayina osiyanasiyana, koma onse ndi ofanana. Onse ndi a chotchingira cholemera, mtundu wa zipangizo zokonzera nyumba ndi zida za zitseko. Msika waukulu wasintha dzina lake ndi malo ake, ndiye kodi mawonekedwe a chotchingira chokhazikika ndi otani poyerekeza ndi chotchingira chachikhalidwe chomwe chinalipo zaka makumi angapo zapitazo? Tiyeni tikambirane nkhani za lero!

Ndi chitukuko cha nthawi ndi kupita patsogolo kwa anthu, malo ambiri apangidwa ndikugwiritsidwa ntchito ndi anthu, monga nyumba zazitali, ndipo malo ambiri amafunika kutetezedwa ndi maukonde otetezera. Kodi mukudziwadi za maukonde otetezera? Onerani nkhani iyi ndi ine.

Ukonde woteteza aluminiyamu ndi ukonde woteteza ndi mtundu wa ukonde womangidwa pamalo okwera kwambiri kuti usagwe, womwe umagwiritsidwa ntchito m'njira zosiyanasiyana. Ndiye kodi umagwira ntchito bwanji? Tiyeni tikambirane nkhaniyi ndipo ndikukuuzani.

Popeza ndi hinge yayikulu kwambiri pamsika pakadali pano, hinge ya giya yokhazikika ili ndi magwiridwe antchito abwino kwambiri. Mwachitsanzo, imatha kupirira dzimbiri, kukana madzi komanso kupewa moto, ndipo imatha kunyamula kulemera kopitilira 250kg. Kugwira ntchito bwino kwambiri kumapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri, ndipo ingagwiritsidwe ntchito m'malo osiyanasiyana komanso m'mafelemu osiyanasiyana a zitseko. Ndiye, ngati hinge ya giya yokhazikika ikumana ndi chitseko chachikulu kwambiri cha moto chokhala ndi kutalika kwa mamita 4.2 ndi kulemera kwa 250kg pachitseko chilichonse, kodi ingagonjetse bwino? Tiyeni tidikire tiwone!

Chifukwa cha kuchira kwachuma padziko lonse lapansi komanso kukwera kwa misika yatsopano, ma profiles a aluminiyamu akukondedwa chifukwa cha makhalidwe awo abwino monga kulemera kopepuka, mphamvu zambiri komanso kukana dzimbiri. Pankhani ya zomangamanga, ma profiles a aluminiyamu amagwiritsidwa ntchito kwambiri pazitseko ndi mawindo, makoma a nsalu, nyumba zadenga ndi zinthu zina zomangira. Mu zida za zitseko ndi mawindo, ma hinges a giya yopitilira amawonekera pang'onopang'ono m'munda wa masomphenya a anthu. Poyerekeza ndi ma hinges wamba wamba, ali ndi mipata yoonekeratu, zomwe zimapangitsa kuti magwiridwe antchito awo ndi momwe amagwiritsidwira ntchito zikhale zosiyana. Komabe, mawonekedwe a ma hinges a giya yopitilira apangitsa minda yosiyanasiyana kuwona chitukuko cha ma alloy a aluminiyamu, zomwe zidzayambitsa ma profiles a aluminiyamu m'dziko lamtsogolo, lomwe likugwirizana kwambiri ndi izi.

Ndi chitukuko cha sayansi ndi ukadaulo komanso kusintha kwa miyoyo ya anthu mosalekeza, ma hinge okhazikika okoka chidwi cha anthu ambiri. Amalonda ena omwe amagwiritsa ntchito ma hinge achikhalidwe ayamba kugwiritsa ntchito ma hinge athu atsopano, ndipo magwiridwe antchito awo asintha kwambiri. Kodi hinge yatsopanoyi yomwe yakoka chidwi cha anthu ndi chiyani kwenikweni? Tiyeni tiyambe nkhani.
