Yintoni ebangela umhlwa ngundo?

Umhlwa ngumhlwa yinto eqhelekileyo kwaye ibangelwa zizizathu ezikhethekileyo. Akuyongxaki kumgangatho wentsimbi. Namhlanje ndiza kukuxelela ukuba yintoni ebangela umhlwa ngundo.

Oyena nobangela wokurusa ngundo kunye nezisombululo:

(1) Irhasi eveliswa kukunyibilika kokunyibilika (i-corrosion)

Ezinye izinto ezikrwada ziya kuvelisa iigesi eziguquguqukayo xa kushushu. Ezi gesi zinokutya kwaye ziya kutshabalalisa ukungunda. Ngoko ke, kuyimfuneko ukulawula ubushushu bombhobho ukuze ungagqithisi, kwaye xa izixhobo ziyeka ukusebenza, hlambulula isikhunta ngendwangu ethambileyo kwaye uvale isikhunta. Ukuba ayisetyenziswanga ixesha elide, fafaza i-agent anti-rust kwi-mold cavity, kwaye xa uvala i-mold. Faka ibhotela kunye neplagi ye-sprue.

(2) Ukupholisa amanzi kubumba

Amanzi okupholisa ahlala esetyenziselwa ukubumba ukupholisa, ngoko kukho umphunga omninzi wamanzi ojikeleze izixhobo zokubumba. Ukuba ukungunda kupholile ngaphantsi kwendawo yombethe, ukufuma okusemoyeni kuya kwenza amathontsi amanzi kumphezulu wokungunda. Ukuba ayicinywanga ngexesha, iya kuba nomhlwa lula. Ngokukodwa emva kokuba isikhunta siyeke ukusebenza, amanzi okudibanisa aya kuveliswa ngokukhawuleza. Ngoko ke, xa umisa ukubumba, amanzi okupholisa kufuneka aphinde acinywe kwaye isikhunta kufuneka somiswe.

(3) I-Carbide eveliswa ngexesha lokubumba

Emva kokuba i-mold isebenze ixesha elide, izinto zokubumba ziya kudlula kwaye zibole ukuze zenze i-carbides, ebuye ihlasele kwinqanaba elithile kwaye ihlala ibangela ukuba i-mold igqoke, i-corrode okanye i-rust. Kule nkalo, ukuba i-carbides ifunyenwe ukuba yenziwe okanye amaconsi amanzi avela, kufuneka asuswe ngokukhawuleza.

(4) Indawo yogcino

Ngethuba lokugcinwa kwenkqubo, ukuba isikhunta sigcinwa kwindawo enomswakama ixesha elide, lixhomekeke kwi-rust. Kule nkalo, kufuneka silawule ukufuma kwe-ambient, sigcine indawo apho isikhunta sigcinwa kusomile kwaye singena umoya, kwaye siphephe indawo emanzi.

(5) Inkqubo yokusetyenziswa

Ukuba isikhunta asikhathalelwanga kakuhle kwaye sigcinwe ngexesha lokusetyenziswa, kuya kuba neengxaki zokugqwala. Kule nkalo, xa usebenzisa i-molds, kuyimfuneko ukuqinisa ukunakekelwa kunye nokugcinwa, ukucoca kunye nokusebenzisa ioli echasene ne-rust ngexesha.

Nangona i-rust ye-mold yingxaki eqhelekileyo, ukuba nje sisazi kakuhle amanyathelo okuphucula achanekileyo, sinokuyiphepha ngokufanelekileyo le ngxaki, ngaloo ndlela siqinisekisa ubomi benkonzo yokubumba kunye nomgangatho wemveliso.
