Iyunithi yeshubhu edonswa ngokubanda
Inhlanganisela ebandayo egoqekayo, edonswa ukubanda noma egoqiwe futhi ebandayo yenqubo yokusebenza ebandayo ukuze kukhiqizwe iphakheji yepayipi yezinhlanganisela zemishini. Kuyipayipi elishiselwe eligoqiwe elishisayo noma amayunithi okucubungula ukujula kweshubhu. Ngokusekelwe ezintweni zokucubungula zensimbi, usayizi wepayipi, izidingo zekhwalithi...Funda kabanzi -
Inqubo yokukhetha ipayipi lensimbi
Okubizwa kanjalo kusetshenziswa i-hydrofluoric acid nesisombululo se-nitric acid ukugeza i-steel surface oxide ekhiqizwa ngemva kokwelashwa ngokushisa. Isetshenziswa ekubunjweni kwesixazululo namanani wesilinganiso: HF (3-8%), HNO3 (10-15%), H2O (inani elisele) lapho kucutshungulwa izinga lokushisa lesisombululo ku-40-60 °C. Isithombe sepayipi lensimbi...Funda kabanzi -
Ipayipi lokudonsa amanzi
Ipayipi lokukhipha indle libhekise ekuqoqweni nasekukhishweni kwendle, amanzi angcolile kanye nohlelo lokudonsa amanzi emvula kanye nezinsiza ezixhumene nazo. Kubandakanya ipayipi elomile, ipayipi legatsha kanye nepayipi eliholela ezimbonini zokwelapha, Kungakhathaliseki ukuthi ipayipi elisemgwaqweni noma kunoma iyiphi enye indawo, inqobo nje uma lidlala ...Funda kabanzi -
Uhlobo Lwepayipi Lensimbi Elisetshenziselwa Ukuthuthwa Kwamafutha
Ukucutshungulwa, ukuthuthwa nokugcinwa kwamafutha kuyinkimbinkimbi kakhulu ngengcindezi ephezulu kanye nokugqwala. Uwoyela ongahluziwe ovela ngaphansi komhlaba uqukethe izinto ezifana nesulfure ne-hydrogen sulfide ezingase zikhiphe ipayipi. Lokhu kuyinkinga ebalulekile ngesikhathi sokuthutha uwoyela. Ngakho-ke, impahla ...Funda kabanzi -
Uyini umehluko phakathi kokuhlolwa kwepayipi le-ut ne-x-ray
Ukusetshenziswa kwezindlela zokuhlola i-ultrasonic ukuthola ithuluzi elibizwa ngokuthi umtshina we-ultrasonic flaw. Umgomo wayo uthi: ukusakazeka kwegagasi le-ultrasonic endabeni kuyatholwa, izakhiwo ze-acoustic zezinto ezibonakalayo kanye nezinguquko zenhlangano yangaphakathi zinomthelela othile ekusakazweni kwe-ul...Funda kabanzi -
I-Zinc coating
I-Zinc iyinqubo yokusabela kwe-metallurgical. Ngokombono we-microscopic, inqubo ye-hot dip galvanizing ibhalansi emibili eguquguqukayo, ibhalansi yokushisa kanye nokulingana kokushintshisana kwe-zinc iron. Lapho i-workpiece yensimbi icwiliswa cishe ku-450 ℃ oketshezi oluncibilikisiwe lwe-zinc, ukumuncwa kwe-zinc kwegumbi lokushisa...Funda kabanzi
