2, Tsiva pfuti yesimbi
3, Gadzirisa kurodha vhoriyamu yekuputika kwepfuti, yemagetsi ikozvino uye nguva yekuputika (yakakosha workpiece haigone kupfurwa kuputika)

3.Kuchembera kwemvura yetangi
Kuongorora kwechikonzero:
1, Chiedza chezuva chinopenya pamvura yetangi
2, Asidhi, alkali, phosphoric acid, hydrochloric acid kana organic zvinonyungudutsa zviri mumvura yetangi.
3, Simbi inopfurwa uye ngura zviri mumvura yetangi
4, Iyo indekisi yekuputira mvura haina kujairika
5, Tangi mvura haiwanzo kuvandudzwa
Solution:
1, Dzivisa kuvhenekwa kwezuva kumvura yetangi
2, Tangi mvura inofanira kunge iri kure neasidhi, alkali uye organic zvinhu, nezvimwe.
3, Kugara kucheneswa kwetangi, ine 100 mesh sefa, uchiisa magineti mumvura yetangi.
4, Ongorora tangi mvura zuva nezuva uye gadzirisa nenguva
5, Dzora tembiricha yekuchengetera yetangi mvura (10 ℃) zvakasimba, uye igadzirise zvisirizvo kana zvichidikanwa.

4. Kusabatana kwakashata kweworkpiece
Kuongorora kwechikonzero:
1, Kubviswa kwemafuta kusina kukwana
2、Ballast mhando haina kunaka
3, Slot mvura kuchembera, isina kugadzikana zviratidzo uye kusvibiswa mune slot fluid
4, Kurapa tembiricha uye nguva hazvina kukwana
5, Iyo yekuputira layer yakanyanyisa
Solution:
1, Tarisa mhedzisiro yekubvisa mafuta
2, Tarisa kunaka kwekupfurwa kwepfuti
3, Ona uye gadzirisa tangi fluid index panguva
4, Tarisa kurapa tembiricha uye nguva
5, Gadzirisa ukobvu hwekuputira kuti uve nechokwadi chekufukidzira uye nguva yekupfapfaidza munyu

5. Workpiece ine effusion
Kuongorora kwechikonzero:
1, Viscosity yakawandisa, tembiricha yebasa yakakwira zvakanyanya
2, Inononoka centrifugal kumhanya, nguva shoma, nguva pfupi
3, Iyo workpiece ine mabubbles mushure mekunyudza coating
4, Special workpiece
Solution:
1, Dzikisa viscosity kune huwandu, iyo workpiece inofanira kutonhodzwa kusvika kune tembiricha yekamuri isati yapfeka
2, Gadzirisa iyo centrifugal nguva, nhamba yenguva uye kumhanya kwekutenderera
3, Furidza workpiece pabhandi remambure mushure mekupotera
4, Shandisa bhurashi sezvinodiwa

6.Poor anti-corrosion performance ye workpiece
Kuongorora kwechikonzero:
1, Kubviswa kwemafuta kusina kukwana
2, Hunhu hwekupfurwa kwepfuti hauna kunaka
3, Slot mvura kuchembera, isina kugadzikana zviratidzo uye kusvibiswa mune slot fluid
4, Kurapa tembiricha yakanyanya kana kuderera, kwete nguva yakakwana
5, Kupfeka mari hakuna kukwana
Solution:
1, Tarisa mhedzisiro yekubvisa mafuta
2, Tarisa mhedzisiro yepfuti blasting
3, Ongorora tangi mvura zviratidzi uye gadzirisa zuva nezuva
4, Tarisa tembiricha yekupisa uye gadzirisa nenguva
5, Imwe neimwe yakaputirwa nehuwandu hwakanaka hwekuputira huwandu hwekuyedza, kuitira kugadzirisa maitiro
