I-Zinc casting ingagcotshwa ngempushana

i-zinc casting ingaba yimpuphu

Ingxenye ekhonjiwe izoba ne-porosity engase ibangele amabala ekugqoke ekushiseni okuphezulu. Umoya obambeke eduze kwendawo ungase unwebe futhi udabule ifilimu phakathi nenqubo yokwelapha. Ziyisikhombisaral izindlela zokunciphisa inkinga. Ungakwazi ukushisa kuqala ingxenye ukuze ushayele omunye womoya ovaleleke obangela inkinga. Shisisa ingxenye ekushiseni okungaba ngu-50°F okukhulu kunezinga lokushisa lokwelapha, lipholise phansi, bese usebenzisa okokunamathela. Ukwelapha ngezinga lokushisa eliphansi ngangokunokwenzeka ukuze ukhawulele inkinga. Ungasebenzisa futhi impushana eyakhelwe umjikelezo wokugeleza ozosiza ukukhulula umoya ngaphandle kokushiya sici.

Ukunamathela kokuphonswa kwe-zinc kungenye inkinga. Uma i i-powder coatings unganamatheli, kungenxa yokuthi awuzange uhlanze futhi ulungise indawo efanele. Udinga ukususa yonke inhlabathi ephilayo (amafutha, amafutha, ukungcola), futhi kungase kudingeke ukuthi upholishe noma uqhumise indawo engaphezulu ukuze ukhiphe inhlabathi engaphili (ukukhululwa kokufa noma izinhlanganisela ezifanayo). Bheka isimo sokuhluleka kokunamathela. Ingabe ikuzo zonke izingxenye zomhlaba noma kungenzeka ukuthi yenzeke ezindaweni ezifanayo ngaso sonke isikhathi? Uma ikhona yonke indawo, ingxenye ayihlanzeki, futhi udinga isicoci esinolaka esinokushisa okwengeziwe. Uma isezindaweni ezingazodwa, kungenzeka ukuthi iwumkhiqizo okhishwa ngokufa. I-iron phosphate ishiya ifilimu ku-zinc, kodwa akuyona into eguquguqukayo yangempela ye-zinc. uzama isinyathelo sokupholisha (uwisa izingxenye kudivayisi edlidlizayo, ukuhlanzwa nge-ultrasonic noma enye indlela efanayo) ukuze ubone ukuthi inkinga ngama-ejenti akhipha ukufa. Khuluma nomhlinzeki wamakhemikhali futhi mayelana nokucwaninga okuphelele kwengxenye kanye nezinketho zokuzilungiselela.
