Kufa kuponyera zinthu zachitsulo mwamakonda
Kufa kuponyera ndi njira yoponyera chitsulo, yomwe imadziwika ndi kugwiritsa ntchito mkatikati mwa kufa kuti mugwiritse ntchito kuthamanga kwazitsulo. Nkhungu nthawi zambiri zimapangidwa ndi zitsulo zamphamvu kwambiri, zomwe zimakhala zofanana ndi jekeseni. Ambiri amafa amakhala opanda chitsulo, monga zinc, mkuwa, aluminium, magnesium, lead, malata ndi aloyi aloyi ndi alloys awo. Malinga ndi mtundu wa kufa kuponyera, m'pofunika kugwiritsa ntchito ozizira chipinda kufa kuponyera makina kapena chipinda otentha kufa kuponyera makina.
Mtengo wa zida zoponyera ndi nkhungu ndizokwera, chifukwa chake njira zoponyera zimagwiritsidwa ntchito pakupanga zinthu zambiri. Ndiosavuta kupanga magawo oponyera kufa, omwe amafunikira magawo anayi okha, ndipo kukwera mtengo kumodzi kumakhala kotsika kwambiri. Kufa kuponyera kumakhala koyenera makamaka pakupanga kuchuluka kwakapangidwe kakang'ono ndi kakang'ono, kotero kuponyera kufa ndikogwiritsidwa ntchito kwambiri m'njira zosiyanasiyana. Poyerekeza ndi umisiri ena kuponyera, pamwamba pa kufa kuponyera ndi see ndipo ali apamwamba ooneka enieni kugwirizana.
Kutengera ndondomeko yachikhalidwe chakufa, njira zingapo zabwino zidabadwa, kuphatikiza njira yoponyera yoperewera kuti ichepetse kuponyera ndikuchotsa pores. Ndi njira yojambulira mwachindunji yomwe imagwiritsidwa ntchito pokonza zinc, zomwe zimatha kuchepetsa zinyalala ndikuwonjezera zokolola.
Zitsulo zomwe zimagwiritsidwa ntchito poponyera makamaka zimaphatikizapo zinc, mkuwa, aluminium, magnesium, lead, malata ndi malata a lead. Ngakhale chitsulo chosindikizidwa ndichosowa, ndichotheka. Zida zapadera zopangira zida monga Zamak, aluminium zinc alloy ndi American Aluminium Association miyezo: aa380, aa384, aa386, aa390 ndi AZ91D magnesium. Makhalidwe a kufa kuponyera zitsulo zosiyanasiyana ndi awa:
Zinc: chitsulo chosavuta kwambiri kuponyera. Ndizochuma kwambiri kupanga magawo ang'onoang'ono, osavuta kuvala, kulimba kwakukulu ndi pulasitiki, komanso moyo wautali woponyera.
Aluminiyamu: kulemera kopepuka, kupanga kovuta komanso mipanda yaying'ono imakhala yolimba kwambiri, kukana kwamphamvu kwa dzimbiri, makina abwino, magwiridwe antchito komanso madutsidwe, komanso kutentha kwambiri.
Magnesium: yosavuta makina, mphamvu yayikulu mpaka kulemera kwake, chopepuka kwambiri chomwe chimagwiritsidwa ntchito poponya zitsulo.
Mkuwa: ili ndi kuuma kwakukulu komanso kukana kwamphamvu kwa dzimbiri. Zina mwazitsulo zomwe zimagwiritsidwa ntchito kwambiri, zimakhala ndi makina abwino kwambiri, kuvala kulimba ndi mphamvu pafupi ndi chitsulo.
Kukuthandiza ndi malata: mkulu osalimba, mkulu ooneka enieni olondola, angagwiritsidwe ntchito ngati mbali yapadera odana ndi dzimbiri. Pazifukwa zaumoyo wa anthu, aloyi sangathe kugwiritsidwa ntchito pokonza chakudya ndi zida zosungira. Chitsulo cha lead, malata ndi antimoni (nthawi zina chimakhala ndi mkuwa pang'ono) chitha kugwiritsidwa ntchito kupanga mtundu wamawonekedwe ndi bronzing mu kusindikiza kwa letterpress.
