zinc casting inogona kuve yakafukidzwa neupfu

Chikamu chakakandwa chichava ne porosity iyo inogona kukonzera mavanga mukuputira pakupisa kwakanyanya. Mhepo yakavharirwa pedyo nepamusoro inogona kuwedzera uye kuputika firimu panguva yekurapa. Kune vanomweral nzira dzekugadzirisa dambudziko. Iwe unogona preheat chikamu kuti udzinge imwe yemhepo yakabatwa inokonzera dambudziko. Pisa chikamu kusvika kune tembiricha inenge 50 ° F yakakura kupfuura tembiricha yekurapa, itonhodze pasi, uye isa iyo yekupotera. Mushonga patembiricha yakaderera inokwanisika kuderedza dambudziko. Iwe unogonawo kushandisa poda inogadzirirwa kutenderera inoyerera iyo inobatsira kusunungura mhepo pasina kusiya gwapa.

Iko kunamatira kune zinc casting imwe nyaya. Kana iyo kupfeka hupfu usanamatira, imhaka yekuti hauna kuchenesa nekugadzirira nzvimbo yacho nemazvo. Iwe unofanirwa kubvisa ivhu rose reorganic (girisi, mafuta, tsvina), uye ungangofanira kupukuta kana kuputika pamusoro kuti ubvise ivhu rekusagadzikana (kufa kusunungurwa kana makomisheni akafanana). Tarisa chimiro chekukundikana kwekunamatira. Iri pamativi ese epamusoro here kana kuti zvimwe zvingangoitika munzvimbo dzakafanana nguva dzese? Kana iri kwese kwese, chikamu chacho hachina kuchena, uye iwe unoda imwe yehasha yekuchenesa nekupisa kwakawanda. Kana iri munzvimbo dziri kure, ingangove chigadzirwa chinofa. Iron phosphate inosiya firimu pane zinc, asi haisi yechokwadi yekushandura coating ye zinc. unoedza nhanho yekupolish (kudonhedza zvikamu mumudziyo unozunguza, kuchenesa kweultrasonic kana imwe nzira yakafanana) kuti uone kana dambudziko riri kufa-release agents. Taura nemutengesi wemakemikari zvakare pamusoro pekuongorora kwakakwana kwechikamu uye zvingasarudzwa zvekugadzirira.
