Maxay yihiin daawaynta dusha sare ee dunta la geliyo?

Daawaynta dusha gelinta dunta waxa loola jeedaa habka samaynta lakabka daboolka ah ee dusha sare ee workpiece iyada oo loo marayo hab gaar ah. Ka dib daaweynta dusha sare, dhejisyada duntu waxay soo bandhigi karaan muuqaal qurux badan, iyo iska caabinta daxalka ee dunta la geliyo lafteeda ayaa sidoo kale la hagaajin doonaa. Ujeedada ugu muhiimsani waa in dunta lafteeda la geliyo ka hortagga daxalka, si kor loogu qaado isku halaynta iyo la qabsiga xiraha. Korantada, galvaning-ku-kulul, iyo dahaadhaynta farsamada waa saddexda hab ee ugu badan ee loo isticmaalo daawaynta dusha sare ee dunta la geliyo.

1. Korantada
Koronto-siinta dunta la geliyo waxa loola jeedaa ku-midida qaybaha dunta ee u baahan in lagu dhejiyo xal gaar ah oo aqueous ah.. Xalka aqueous wuxuu ka koobnaan doonaa qaar ka mid ah xeryahooda birta ah ee la shubay. Sidan, ka dib marka hadda la marayo xal aqueous, Walxaha birta ah ee xalka ku jira ayaa soo dada oo ku dheggan dunta la geliyo. qaybta la geliyey ee firmware-ka. Ku xidhidhiyeyaasha korantada guud ahaan waxa ka mid ah dahaadhidda zinc, naxaas, nikkel, chromium, daawaha copper-nickel, iwm. Mararka qaarkood madow karkaraya (buluug), fosfatinta, iwm. ayaa sidoo kale lagu daray.

2. Galvanization-ka kulul
Galvanization-ku-kulul ee xirayaasha waa in la geliyo dunta birta kaarboonka ah ee la geliyo qubeyska dahabka dhalaalaysa ee leh heerkul dhan 510°C, si birta-zinc daawaha ee dusha sare ee xiraha loogu beddelo zinc passivated. Si aad u hesho saamaynta daaweynta dusha (oo la mid ah dahaadhka aluminiumka kulul ee kulul)

3. Dajinta makaanikada
Dahaadhidda makaanikada dunta la geliyo waxaa loola jeedaa adeegsiga hab gaar ah oo jireed iyo kiimiko si loo saameeyo dusha sare ee dunta la geliyo budada birta ah ee dahaarka leh, si biraha dahaarka leh ay u sameeyaan dahaarka dusha sare ee xiraha iyada oo loo marayo alxanka qabow si loo gaaro saameynta daaweynta dusha sare. Dahaarka makaanikada ee xirmooyinka ayaa inta badan ku habboon qaybaha dheeriga ah sida boolal, looska iyo dhaqida.

Si loo xukumo tayada dunta geliso daaweynta dusha sare, Inta badan waa in la hubiyo in awoodda ka-hortagga daxalka ee dunta duntu ay si wax ku ool ah u korodhay iyo in korodhku buuxiyo shuruudaha la filayo.. Habka kormeerku waa in lagu ekaysiiyo deegaanka shaqada ee alaabta, deji shuruudaha imtixaanka, oo ku samee tijaabooyinka daxalka. Talaabada labaad waa in la hubiyo muuqaalka.
