Ukwakhiwa Kwephayiphu Ku-Aluminium Castings

I-Hydrogen iyimbangela eyinhloko yezimbobo (i-80-90 yegesi encibilike oketshezini lwe-aluminium i-hydrogen), futhi i-hydrogen ikhiqizwa ngokuyinhloko ukubola komhwamuko wamanzi. 

Isizathu sokukhiqiza umusi wamanzi ngesikhathi sokuncibilika kwe-aluminium alloy yisici esiyinhloko esithinta ngokuqondile ukwakheka kwama-pinholes. Izici eziyinhloko ezithinta ukwakheka kwamaphinikhodi yilezi:

Ngesikhathi sokuncibilikiswa kwe-aluminium alloy kanye nenqubo yokuthela, izinto zokusetshenziswa, izinto ezisizayo, amanzi ayikristalu kwezinye izinto, kanye nokugqwala kwe-aluminium AL (OH) 2 kuyabola ukuze kukhiqize umswakama. 

Kunezinto eziningi ezisizayo ze-organic kanye ne-inorganic endabeni yokumodela. Umswakama oqukethwe ezintweni zokuphonsa ezifana nezinto ezisizayo kanye nezingubo zokumboza ngenxa yokushisisa kahle kuqala kuzokhiqiza inani elikhulu legesi ngenxa yokubola komhwamuko wamanzi ngesikhathi sokuncibilika nokuthululwa kwe-aluminium alloy. Lapho kuncibilika imishini ehlukene yokuncibilika aluminium kufas, inani lokungenisa komoya kwe-aluminium alloy kanye nezinga lokubunjwa kwezimbotshana lihlukile. 

Iziphambano ezintsha kanye neziphambano ezindala ezinokugqwala nokungcola kufanele kuqhunyiswe isihlabathi noma zisuswe ngezinye izindlela ngaphambi kokusetshenziswa, futhi zishiselwe ku-700 ℃ -800 ℃ ukuze kukhishwe amanzi nezinye izinto zamakhemikhali ezimuncwe yi-crucible. Umhwamuko wamanzi ukhiqizwa ngesikhathi sokuncibilika nokuthululwa ukuze wenze izimbotshana.

Ngamathuluzi okuncibilikisa, njenge-ladle, ikhava yensimbi yokukhipha umoya, njll., insimbi engaphezulu, isikali se-oxide nokunye ukungcola kufanele kukhishwe ngaphambi kokusetshenziswa; amathuluzi e-aluminium-magnesium alloy kufanele abekwe ku-carnallite ngaphambi kokusetshenziswa Geza ku-flux.

Uma ukushisa kwangaphambi kokushisa kungalungile, umswakama ofakwe phezulu uzokhiqiza inani elikhulu legesi ngenxa yokushisa ukuze wenze umhwamuko wamanzi ngesikhathi sokuncibilika nokuthululwa kwenqubo, okuholela ekwakhekeni kwamaphinikhodi e-aluminium castings.
