Manje imikhiqizo eminingi yokukhiqiza yezimboni izosebenzisa izinto zezintambo zensimbi engagqwali ekukhiqizeni, ukuze kuhlonzwe insimbi engagqwali yomgunyathi, izinyathelo ezithile nezindlela zingathathwa.Nokho, amakhasimende amaningi awazi ukuthi iyiphi indlela engasetshenziswa ukukhomba.Izinhlobo ezilandelayo zezindlela zokuhlonza zibhalwe nguI-Gepair tensile mesh.
1, Indlela yokuhlola Magnetic
Indlela yokuhlola kazibuthe iwumehluko wangempela novame kakhulu phakathi kwe-austenitic stainless steel kanye ne-ferritic stainless steel iyindlela elula, i-austenitic stainless steel ayiyona insimbi kazibuthe, kodwa ngemva kokucindezela okukhulu okubandayo kuzoba nozibuthe omnene;Nensimbi ehlanzekile ye-chromium ne-alloy ephansi. izinsimbi ziyinsimbi enamandla kazibuthe.
2. Ukuhlolwa kwephuzu le-nitric acid
Isici esihlukanisayo sentambo yensimbi engagqwali ukumelana kwayo nokugqwala kwe-nitric acid egxilile, eyenza ihlukaniseke kalula kwezinye izinsimbi noma ama-alloys.Kodwa-ke, izinsimbi eziphakeme ze-carbon 420 nezingu-440 zigqwalile kancane ekuhlolweni kwephoyinti le-nitric acid, futhi izinsimbi ezingenayo insimbi zigqwala ngokushesha ku-asidi ye-nitric egxilile, kuyilapho i-nitric acid ehlanjululwayo inomthelela oqinile wokugqwala ku-carbon steel.
3, i-Copper sulfate point test
Iphuzu le-Copper sulfate zama ukushesha ukuhlukanisa phakathi kwe-carbon steel evamile kanye nendlela elula yazo zonke izinhlobo zentambo yensimbi engagqwali, ukusetshenziswa kwe-concentration ye-copper sulfate yi-5% - 10%, ngaphambi kokuhlolwa kwamaphuzu, indawo yokuhlola. kufanele kususwe kahle uwoyela nokunye ukungcola, indwangu noma umshini wokugaya othambile wokucwebezelisa kanye nomshini wokugaya indawo encane, bese uzama amaconsi ukushisa, i-carbon steel evamile noma insimbi izokwakhiwa phakathi kwemizuzwana embalwaUngqimba lwethusi lensimbi engaphezulu, kanye nengaphezulu iphoyinti lokuhlola insimbi engagqwali ayikhiqizi imvula yethusi noma ibonise umbala wethusi.
4, indlela yokuhlola i-Sulfuric acid
Ukucwiliswa kwe-sulfuric acid yensimbi engagqwali kungahlukanisa u-302 no-304 kusukela ku-316 no-317. Umkhawulo wokusika wesampula kufanele ugaywe kahle, bese uhlanzwa futhi udluliselwe ku-sulfuric acid nge-volume concentration of 20% ~ 30% kanye nezinga lokushisa lama-60. ~66℃ isigamu sehora.Uma ivolumu yesisombululo se-sulfuric acid ingu-10% futhi ishisiswe ku-71 ℃,302 kanye no-304 icwiliswa esixazululweni, insimbi igqwala ngokushesha futhi ikhiqize inani elikhulu lamabhamuza, futhi isampula iba mnyama emizuzwini embalwa. Amasampula ensimbi angu-316 kanye ne-317 awagqwali noma agqwalile kancane kakhulu (awekho amabhamuza), ukuhlolwa phakathi kwemizuzu eyi-10~15 akushintshi umbala.Ukuhlola kungaba nembe kakhulu uma isampula enokwakheka okwaziwayo isetshenziselwa ukuqhathanisa cishe.
