Iimfuno zokugquma umgubo phezu kwediphu eshushu yokugalela
Le ngcaciso ilandelayo iyacetyiswa: Sebenzisa i-zinc phosphate pretreatment ukuba kukho ukuncamatheliswa okuphezulu. Umphezulu kufuneka ucoceke ngokugqibeleleyo. I-zinc phosphate ayinayo into yokucoca kwaye ayiyi kususa ioli okanye umhlaba. Sebenzisa i-iron phosphate ukuba umsebenzi osemgangathweni uyafuneka. I-iron phosphate inesenzo esincinci sokucoca kwaye iya kususa ungcoliseko oluncinci lomhlaba. Eyona isetyenziswayo kwiimveliso zangaphambili. Umsebenzi wokufudumala ngaphambi kokusetyenziswa komgubo. Sebenzisa i-'degassing' yomgangatho wepolyester yokwambathisa kuphela. Khangela unyango oluchanekileyo nge-solventFunda ngokugqithisileyo …
Izisombululo zeengxaki zokwaleka komgubo phezu kwediphu eshushu yokugalela igalvanizing
1. Ukunyanga okungaphelelanga: Umgubo wePolyester umgubo wokwaleka ngumgubo we-thermosetting resins eziwela ikhonkco ukuya kwifom yazo yokugqibela ye-organic ngokugcinwa kwiqondo lobushushu (ngokuqhelekileyo yi-180 oC), malunga nemizuzu eyi-10. Ii-ovens zokunyanga zenzelwe ukubonelela ngeli xesha ngokudibanisa kweqondo lokushisa. Ngezinto ezishushu zediphu, kunye nobukhulu becandelo elinzima, kuyimfuneko ukuqinisekisa ukuba ixesha elaneleyo lokumisa livunyelwe ukuhlangabezana nemigaqo yokunyanga. Ukufudumeza kwangaphambili komsebenzi onzima kuya kunceda ukukhawulezisa inkqubo yokunyangaFunda ngokugqithisileyo …
