Ndezvipi zvinokonzera ngura yeforoma?

Ngura yekuumbwa chinhu chinowanzoitika uye inokonzerwa nezvikonzero zvakakosha. Haisi dambudziko nehutano hwesimbi. Nhasi ndichakuudza chinokonzeresa ngura yekuumbwa.

Zvikonzero zvikuru zvefodya ngura uye mhinduro:

(1) Gasi rinogadzirwa nekunyunguduka (kuora)

Zvimwe zvinhu zvinogadzirwa zvinogadzira magasi anoputika kana apiswa. Magasi aya ane ngura uye anoparadza mold. Nokudaro, zvakakosha kudzora kutonhora kwebhodhoro kuitira kuti usapisa, uye kana midziyo inomira kushanda, chenesa mold nemucheka munyoro uye uvhare mold. Kana ikasashandiswa kwenguva yakareba, pfapfaidza anti-rust agent mugomba rekuumbwa, uye zvakare kana uchivhara mold. Isa bhotela uye plug the sprue.

(2) Mvura inotonhorera muforoma

Mvura inotonhorera inowanzo shandiswa muforoma yekutonhodza, saka kune yakawanda yemvura mhute yakatenderedza midziyo yekuumba. Kana mold ikatonhodzwa pazasi pedova, mwando uri mumhepo uchaita madonhwe emvura pamusoro pefova. Kana ikasadzimwa nekufamba kwenguva, inoita ngura nyore. Kunyanya mushure mekunge mold yamira kushanda, mvura ye condensation inogadzirwa nekukurumidza. Nokudaro, pakumisa kuumbwa, mvura inotonhorera inofanirawo kuvharwa uye mold inofanira kupukuta yakaoma.

(3) Carbide inogadzirwa panguva yekuumbwa

Mushure mekunge mold yave ichishanda kwenguva yakareba, iyo yekuumba inodonha uye inoparara kuti iite carbides, iyo inoodzawo kune imwe nhanho uye inowanzoita kuti mold ipfeke, marara kana ngura. Panyaya iyi, kana ma carbides akawanikwa akaumbwa kana madonhwe emvura achionekwa, anofanira kubviswa pakarepo.

(4) Kuchengetera nzvimbo

Munguva yekuchengetedza, kana mold ichichengetwa munzvimbo ine hunyoro kwenguva yakareba, inowanzoita ngura. Panyaya iyi, tinofanira kudzora humidity yakapoteredza, kuchengetedza nzvimbo iyo mold inochengeterwa yakaoma uye ine mhepo, uye kudzivisa nzvimbo ine hunyoro.

(5) Maitiro ekushandisa

Kana iyo mold isingatarisirwi zvakanaka uye kuchengetedzwa panguva yekushandiswa, inozoitawo kumatambudziko emarara. Panyaya iyi, kana uchishandisa molds, zvakakosha kusimbisa kutarisira nekugadzirisa, kuchenesa uye kushandisa mafuta anorwisa-rust munguva.

Kunyangwe ngura iri dambudziko rakajairika, chero bedzi isu tichiziva nzira dzekuvandudza dzakaringana, tinogona kudzivirira dambudziko iri, nekudaro tichiona hupenyu hwesevhisi yehuku uye kunaka kwechigadzirwa.
