Izimfuneko zokumboza impushana phezu kokufakwa uthayela kwediphu elishisayo
Ukucaciswa okulandelayo kuyanconywa: Sebenzisa i-zinc phosphate pretreatment uma ukunamathela okuphezulu kuyadingeka. Ubuso kufanele buhlanzeke ngokuphelele. I-Zinc phosphate ayinawo isenzo sokuhlanza futhi ngeke isuse amafutha noma inhlabathi. Sebenzisa i-iron phosphate uma ukusebenza okujwayelekile kuyadingeka. I-iron phosphate inesenzo esincane sokuhlanza futhi izosusa inani elincane lokungcoliswa kwendawo. Okusetshenziswa kakhulu emikhiqizweni efakwe ngaphambili. Umsebenzi wokushisa ngaphambi kokufaka i-powder. Sebenzisa 'degassing' grade polyester powder coating kuphela. Hlola ukuphulukiswa okulungile nge-solventFunda kabanzi …
Izixazululo zezinkinga zokumboza impushana phezu kokufakwa kwamadiphu ashisayo
1. Ukwelapha okungaphelele: I-polyester powder coating powder iyinhlaka ye-thermosetting exhumanisa esimweni sawo sokugcina sezinto eziphilayo ngokugcinwa ezingeni lokushisa (imvamisa engu-180 o C), cishe imizuzu eyi-10. Amahhavini okwelapha aklanyelwe ukunikeza lesi sikhathi ekuhlanganiseni kwezinga lokushisa. Ngezinto ezishisayo ze-dip galvanized, ezinobukhulu besigaba esisindayo, kuyadingeka ukuqinisekisa ukuthi isikhathi esanele sokumisa sivunyelwe ukuhlangabezana nezincazelo zokuphulukisa. Ukushisa kwangaphambili komsebenzi osindayo kuzosiza ekusheshiseni inqubo yokwelaphaFunda kabanzi …
