Kodi maziko a granite ayenera kusankhidwa kuti azigwiritsidwa ntchito popanga zida zoyika nkhungu?

Pokonza ndi kupanga nkhungu, maziko a granite amagwira ntchito ngati "chokhazikika" cha zidazo, zomwe zimakhudza mwachindunji kulondola kwa kuyika kwa nkhungu ndi mtundu wa chinthucho. Ndiye, mungasankhe bwanji maziko oyenera a granite?

Choyamba, kulondola ndiye chinsinsi. Kukhazikitsa nkhungu kumafunikira kulondola kwambiri. Chisamaliro chapadera chiyenera kuperekedwa pa kusalala ndi kulunjika kwa maziko. Maziko a granite apamwamba kwambiri ali ndi kusalala mkati mwa ± 0.5μm/m ndipo cholakwika cha kulunjika sichingapitirire ± 0.3μm/m. Monga momwe nyumba yokhala ndi mabuloko imakhalira, maziko ake akamakhala osalala, nkhunguyo idzayikidwa molondola, ndipo kukula kwa zinthu zomwe zimapangidwa kudzakhala kogwirizana ndi miyezo.

Kachiwiri, mphamvu yonyamulira siinganyalanyazidwe. Kulemera kwa nkhungu zosiyanasiyana kumasiyana kwambiri. Nkhungu yaying'ono yobayira ikhoza kulemera makilogalamu mazana angapo okha, pomwe nkhungu yayikulu yopangira die-casting imatha kulemera matani angapo. Posankha maziko, ndikofunikira kufananiza mphamvu yonyamula katundu kutengera kulemera kwa nkhungu ndikusunga malire otetezeka a 20% mpaka 30%, monga momwe mungagulire shelufu yokhala ndi mphamvu yayikulu yonyamula katundu kuti mupewe kudzaza kwambiri ndi kusinthika.

Kuphatikiza apo, kugwedezeka kumachitika panthawi yokonza nkhungu, zomwe zimafuna kuti maziko akhale ndi mphamvu yabwino yochepetsera kugwedezeka. Mwachibadwa, granite ili ndi mphamvu zabwino kwambiri zochepetsera kugwedezeka ndipo imatha kuyamwa kugwedezeka kwapamwamba kwambiri kwa 90%. Kusankha maziko okhala ndi chiŵerengero chochepera 0.02 kungathandize kuchepetsa zizindikiro za kugwedezeka pamwamba pa nkhungu ndikupangitsa kuti pamwamba pa chinthucho pakhale posalala.

Komanso, kuyanjana kwa kuyika ndikofunikira kwambiri. Malinga ndi njira yokhazikitsira nkhungu, sankhani maziko okhala ndi malo oyenera a T ndi mabowo olumikizidwa. Ngati ndi nkhungu yokhala ndi mawonekedwe apadera, maziko osakhazikika amathanso kusinthidwa. Nthawi yomweyo, poganizira malo okonzera, ngati akhudzana ndi zinthu monga choziziritsira, granite yomwe yakhala ikuchiritsidwa ndi anti-permeation iyenera kusankhidwa kuti mazikowo asawonongeke.

Bola ngati mutadziwa bwino mfundo zazikuluzikuluzi, mutha kusankha maziko a granite oyenera zida zoyikira nkhungu, ndikuwonetsetsa kuti kupanga bwino!
