Zinthu zopangira waya wachitsulo wokonzedwa kale zakhala zikufufuzidwa kwambiri kuyambira pomwe zidapangidwa ndikugwiritsidwa ntchito m'mafakitale m'zaka za m'ma 1920. Zotsatira zake, mitundu yosiyanasiyana ya zinthu zomwe zili ndi makhalidwe osiyanasiyana zoyenera kugwiritsidwa ntchito zosiyanasiyana zapangidwa. Izi zikuphatikizapo waya wachitsulo wokokedwa ozizira, waya wachitsulo wowongoka komanso wofewa, waya wachitsulo wopepuka, waya wachitsulo wokhuthala, ndi waya wachitsulo wopangidwa ndi chitsulo. Mtundu uliwonse umagwira ntchito yakeyake, kukwaniritsa zosowa zosiyanasiyana za makampani omanga.
1) Muyezo: ASTM A-421
2) Kukula: 3mm-12mm
3) Mphamvu yokoka: ≥1700Mpa
4) Kulemera kwa koyilo: 800-1500kg
5) Kulongedza: Phukusi Loyenera Kuyenda Panyanja
Dziko la zomangamanga ndi uinjiniya lasintha kwambiri pazaka zambiri, zomwe zapangitsa kuti pakhale kupanga ndi kugwiritsa ntchito mawaya osiyanasiyana achitsulo apamwamba kwambiri polimbitsa konkriti. Chimodzi mwa zinthu zatsopanozi ndi waya wachitsulo wopangidwa ndi konkriti wolimbikitsidwa, womwe umadziwika ndi mphamvu zake zapadera komanso kudalirika kwake. Wopangidwa ndi ndodo za waya wotenthedwa ndi chitsulo cha kaboni wambiri, mawaya achitsulo awa amachiritsidwa ndi kutentha ndi kukonzedwa kuzizira kuti akwaniritse mawonekedwe omwe amafunidwa. Ndi kuchuluka kwa kaboni kuyambira 0.65% mpaka 0.85% komanso kuchuluka kochepa kwa sulfure ndi phosphorous (kochepera 0.035%), mtundu uwu wa waya wachitsulo umakwaniritsa zofunikira zolimba zolimbitsa konkriti wolimbikitsidwa.
Masiku ano, mawaya achitsulo opangidwa kale amakhala ndi mphamvu yokoka kwambiri, ndipo mphamvu zake nthawi zambiri zimaposa 1470MPa. Pakapita nthawi, mphamvu za mawaya awa zasintha kuchoka pa 1470MPa ndi 1570MPa kufika pa 1670-1860MPa makamaka. Kuphatikiza apo, kukula kwa mawaya achitsulo awa kwasinthanso, ndipo kukula kwa waya wamba kumasintha pang'onopang'ono kuchoka pa 3-5mm kufika pa 5-7mm. Izi zimatsimikizira kulimba komanso kugwira ntchito bwino m'mapulojekiti osiyanasiyana omanga, zomwe zimapangitsa kuti zinthu zomangira zomangika zikhale zolimba.
Kusinthasintha kwa mawaya achitsulo a konkriti opangidwa ndi zitsulo kumapangitsa kuti akhale ofunikira kwambiri pa ntchito zosiyanasiyana zomanga. Mawaya amenewa, pamodzi ndi zingwe zachitsulo zopangidwa ndi zitsulo, akhala mitundu yachitsulo yopangidwa ndi zitsulo zogwiritsidwa ntchito kwambiri padziko lonse lapansi. Kaya ndi nyumba zogona kapena zamalonda, mapulojekiti a zomangamanga monga milatho ndi ngalande, kapena nyumba zazitali, kugwiritsa ntchito mawaya achitsulo opangidwa ndi zitsulo kumatsimikizira kudalirika ndi mphamvu kwambiri pakulimbitsa konkriti. Kutha kwawo kupirira katundu wolemera, zochitika za chivomerezi, komanso nyengo yoipa kukuwonetsa ntchito yawo yofunika kwambiri popanga nyumba zolimba komanso zolimba.
Pomaliza, mawaya achitsulo a konkriti opangidwa kale asintha kwambiri makampani omanga. Chifukwa cha mphamvu zawo zapadera, zosankha zosiyanasiyana za zinthu, komanso kusinthasintha malinga ndi zofunikira zosiyanasiyana, mawaya awa akhala gawo lofunikira kwambiri pa ntchito zamakono zomanga padziko lonse lapansi. Kupita patsogolo kosalekeza ndi kusinthidwa kwa njira zawo zopangira zinthu kumathandizira kuti agwiritsidwe ntchito kwambiri komanso kukhala ngati muyezo wamakampani omangira konkriti wopangidwa kale.
Kugwiritsa ntchito
Monga makampani otsogola mumakampani opanga zinthu zachitsulo ku China, malonda achitsulo ndi zinthu zamtundu wa "Zana la bizinesi yabwino", makampani ogulitsa zitsulo ku China, "Mabizinesi 100 apamwamba kwambiri ku Shanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yofupikitsidwa ku Zhanzhi Group) imatenga "Umphumphu, Kuchita Zinthu Mwanzeru, Kupanga Zinthu Mwatsopano, Kupambana" ngati mfundo yokhayo yogwirira ntchito, nthawi zonse imapitiliza kuyika zofuna za makasitomala pamalo oyamba.
