Chii chandinofanira kuita kana iyo vacuum choto annealing yakanyanya oxidized?

Muchoto chevacuum annealing, tambo yemhangura inoiswa oxidized, zvichiratidza kuti vacuum choto irikudonha.

1. Tarisa uone kana iyo inoshanda vacuum yepombi yevacuum yakajairika. Shandisa vacuum gauge kutarisa vacuum panopinzwa pombi yevacuum kuti uone kana ichikwanisa kusvika pakutsvaira kwepombi. Kana zvisina kudaro, shandura mafuta, kana kugadzirisa, uye usambofa wakashandura pombi.

2. Shandisa chinonhonga chinobvinza kuti unhonge zvinobuda muvira revacuum. Kana pasina detector yekuvuza (leak detector inodhura zvakanyanya), shandisa acetone (industrial alcohol) kunhonga pari kubvinza, general leak yekuona chiyero i0.2Pa/h, hapafanirwe kuve nedambudziko.
