Izinduku zethusiyizinto ezimise okwenduku ezenziwe ngethusi nezinc alloys, eziqanjwe ngombala wazo ophuzi.Ithusi elinethusi elingu-56% kuya ku-68% linendawo yokuncibilika engu-934 kuya ku-967 degrees.I-Brass inezakhiwo ezinhle zemishini nokumelana nokugqoka, futhi ingasetshenziswa ukwenza amathuluzi anembayo, izingxenye zomkhumbi, amagobolondo ezibhamu, izingxenye zezimoto, izesekeli zezokwelapha, izesekeli zikagesi nezinto ezisekelayo eziwumshini ezihlukahlukene, izindandatho zegiya ze-automobile synchronizer, amaphampu asolwandle, ama-valve, izingxenye zesakhiwo, izesekeli zokungqubuzana, njll.
Izinduku zethusi ezinokuqukethwe okuhlukile kwe-zinc zizophinde zibe nemibala ehlukene.Isibonelo, uma okuqukethwe kwe-zinc kungu-18% -20%, kuzoba okubomvu-okuphuzi, futhi uma okuqukethwe kwe-zinc kungu-20% -30%, kuzoba nsundu-phuzi.Ngaphezu kwalokho, ithusi linomsindo oyingqayizivele lapho lishaywa, ngakho-ke izinsimbi zaseMpumalanga, amasimbali, izinsimbi, izimpondo nezinye izinsimbi zomculo, kanye nezinsimbi zethusi zaseNtshonalanga zonke zenziwe ngethusi.
Yimuphi umsebenzi othize wokulawula ikhwalithi yezinti zethusi?
1. Idivayisi yokumisa ibhande lethusi kufanele ihlolwe futhi ivunyelwe ngumphathi ngaphambi kokuthulula ukhonkolo.
2. Ikhwalithi yokushisela yezihlanganisi zamabhande ethusi kufanele ihlolwe.Lapho umphathi ecabanga ukuthi kuyadingeka, ukuhlolwa kokuvuza kwamafutha kufanele kwenziwe.Ngemuva kokuphumelela ukuhlolwa, ukungcola kwamafutha kufanele kuhlanzwe.
3. Uhlaka lwe-formwork kufanele lumiswe luqine, futhi i-formwork ezinhlangothini zombili zeshidi kufanele isekelwe “Ω” umumo noma ezinye izinhlaka ezisekelayo ukuze kugwenywe ukungahambi kahle nokuvuza kodaka ngenxa yokuguquguquka kwefomu.
4. Isifanekiso esikhethekile esikhethekile kufanele sisetshenziswe ebhande lethusi ukuze kuqinisekiswe ukuthi ishidi libekwe ngokuqinile futhi amalunga awavuzi.
5. Phakathi nenqubo yokuthulula, gwema ukuqoqwa kwama-aggregates amakhulu ebhande lethusi, futhi udlidlize ngokucophelela ukuze uqinisekise ukuthi ukhonkolo ekuhlanganyeleni uminyene.
6. Hlela izinqubo zokuthulula nokudlidliza ngokunengqondo, futhi unake ukugwema ukugcwala ukopha ebhandeni lethusi.
7. Ngesikhathi sokuthela ukhonkolo, usonkontileka kufanele ahlele abasebenzi abakhethekile abazohlola futhi baphathe.Umphathi kufanele aqinise ukuhlolwa kwezingxenye, futhi uma kukhona ukuchezuka kutholakala, usonkontileka kufanele ayalwe ukuthi akulungise ngesikhathi.
8. Naka ukugcwaliswa kwe-backfilling kanye nokuhlanganisa ukhonkolo engxenyeni engezansi yebhande lethusi, futhi wamukele ngokufanelekile ukufakwa kwe-oblique kanye nokudlidliza okuvundlile.
