Ingxubevange yeZinciindawo zokuphosa ukufangoku zisetyenziswa kwiimveliso ezahlukeneyo.Iintlobo ngeentlobo ze-elektroniki kunye nezixhobo zombane zijikelezwe ziimveliso ze-zinc alloy die-casting.Ke ngoko, umgangatho ongaphezulu we-castings uyafuneka ukuba ube phezulu, kwaye izakhono ezifanelekileyo zonyango lomphezulu ziyafuneka.Esona siphene sixhaphakileyo semveliso ye-zinc alloy casting yi-face blistering.
Iimpawu zesiphene: Kukho iivesicles eziphakanyisiweyo kumphezulu weukuphosa ukufa.① Ifunyanwe emva kokufa;② Ityhilwe emva kokupholisha okanye ukusetyenzwa;③ Kubonakala emva kokutshizwa kweoli okanye i-electroplating;④ Ivele emva kokubekwa ixesha elithile.
Uninzi lwe-blistering phezu kwe-alloy ye-zinc lubangelwa yi-pores, kwaye i-pores ininzi i-pores kunye ne-shrinkage imingxuma.Imingxunya isoloko ingqukuva, kwaye uninzi lwemingxuma ecuthekayo ayiqhelekanga.
1. Izinto ezibangela iipores: ① Ngexesha lokuzaliswa kunye nokuqiniswa kwenkqubo yesinyithi esinyibilikisiweyo, imingxuma yenziwa ngaphezulu okanye ngaphakathi kokuphosa ngenxa yokungena kwegesi;② irhasi engenelwe kukuguquguquka kwengubo;③ umxholo werhasi yolwelo lwealloyi uphezulu kakhulu kwaye uyakhawuleza ngexesha lokuqiniswa.
2. Izizathu zokushwabana komngxuma: ①Kwinkqubo yokuqiniswa kwesinyithi esinyibilikisiweyo, umngxuma wokushwabana kwenzeka ngenxa yokuncipha komthamo okanye inxalenye yokugqibela eqinileyo ayinako ukutyiswa ngesinyithi esinyibilikisiweyo;②Ubungqingqwa obungalinganiyo bokuphosa okanye ukufudumeza okungaphelelanga kokugalela kubangela ukuba inxalenye ethile Ukuqina kucothe, kwaye imingxunya yenziwa kumphezulu xa umthamo ucutheka.
Ngenxa yobukho be-pores kunye nemingxuma eyanciphayo, imingxuma ingangena xa iindawo zokufa ziphantsi konyango olungaphezulu.Xa ubhaka emva kokupenda kunye ne-electroplating, igesi emgodini iyanda ngokutshisa;okanye amanzi emngxunyeni aya kujika abe ngumphunga, nto leyo eya kubangela amadyungudyungu kumphezulu wokugalela.
Thumela umyalezo wakho kuthi:
