Abrasive blast kuchenesa

Nzvimbo dzesimbi dzisina kuchena dzichave dzakaputika kuputika-kucheneswa maererano neSSPC-SP10/NACE Nhamba 2 kunze kwekunge yataurwa nemutengi.The blast anchor pattern kana hudzamu hweprofile ichava 1.5 mil kusvika 4.0 mil(38 µm kusvika 102 µm) yakayerwa maererano neASTM D4417.

Preheating

Pombi yakacheneswa inofanira kupiswa patembiricha isingasviki 260 ℃, iyo sosi yekupisa haifaniri kusvibisa pombi.

Ukobvu

Hupfu hwekuputira huchaiswa papombi inopisa pairi yunifomu yekurapa-firimu ukobvu hwemamirimita gumi nemaviri (305μm) kunze kana mukati.Ukobvu hwepamusoro haufanire kudarika 16 mils(406μm) kunze kwekunge zvakurudzirwa nemugadziri kana kutsanangurwa nemutengi.

Optional epoxy performance test

Mutengi anogona kududzira kumwe kuyedzwa kuti amise epoxy performance.Aya anotevera maitiro ekuyedza, ese achaitwa pakugadzira pombi yekuyedza mhete, anogona kutsanangurwa:
1. Cross-section porosity.
2. Interface porosity.
3. Thermal analysis (DSC).
4. Permanent strain (bendability).
5. Mvura nyoro.
6. Impact.
7. Cathodic disbondment test.
