Amaminerali afana nosimende, umcako, umlotha wesihlabathi, i-alunite ngokuvamile anezimpawu zobulukhuni obuqinile nobuqinile。Uma i-valve ejikelezayo isetshenziselwa ukuththa zonke izinhlobo zezinto ezimbiwa phansi, ibeka phambili izidingo eziphakeme zamandla emishini eimishini nokumelana nokugqokwa。minyyakeni engu-20 edlule, siye sazinikela ocwaningweni olukukelana kukingagugi kanye nezimpawu ezingagugi, samisa isikhungo sokuhola sangaphakathi sezinto zokusebenza, futhi senza ucwaningo oluningi nokuhola, njengokuhola ukumelana nokugqokwa。Zezinto ezihlukahlukene ezihahambisana namaminerali ahlukahlukene, ukuhhlwakk合金材料，ukuhlwakk涂层接合，jki odongeni lwangaphakathi lwempala, j .;Ezinye zezimpumelelo zethu zithole isitifiketi selungeli lobunikazi sikazwelonke, futhi imikhiqizo yethu akazele ukusebenza kwayo nokwethebeka ekusebenzeni okungokoqobo. .
