ukuhlaziywa kwenqubo yokwehluleka ukugqwala kanye nezinyathelo zokuphikisa ze-tinplate yezingxenye ezintathu zethangi
Ukugqwala kwe-tinplate can

Ukugqwala kwemikhiqizo yokupakishwa kwensimbi kubangelwa ukungazinzi kwe-electrochemical kwento equkethwe ukugqwala.Izinto eziyinhloko ezimelana nokugqwala zethangi elinezicucu ezintathu ze-tinplate ukunamathela komzimba wethangi, ungqimba lwe-tinplate lokucwenga kanye nongqimba lwensimbi, kanye nekhava yangaphezulu kanye nesembozo esingaphansi esiqukethe okokunamathela.Ngenxa yokuthi imikhiqizo yokupakisha yensimbi inesikhathi esithile seshalofu, lapho ithini lingakwazi ukuklama impilo yokugqwala kukhulu kunokuthi impilo yeshalofu ingahlangabezana nezidingo zokukhiqiza, ukuqinisekisa ikhwalithi nokuphepha kokudla nesiphuzo esikhathini sokuphila kweshalofu, ukugqwala okuningi kakhulu. imajini iyikhwalithi eyeqile, khulisa izindleko zezomnotho zemikhiqizo.Ukuze kucatshangelwe izidingo zempilo yokuklama okufanelekayo nokonga kwezomnotho ngesikhathi esifanayo, ukukhiqizwa kwamathini aneziqephu ezintathu ze-tinplate kunezidingo ezinembile zezinto zokusetshenziswa nezinqubo, futhi kugcina ikhwalithi yemikhiqizo.

Umsebenzi wokuhlola ubonisa ukuthi ungqimba, ungqimba lukathayela kanye nongqimba lwensimbi lwe-tinplate yizithiyo eziyinhloko zokuvikela ukugqwala kwethangi.Izinto zokusetshenziswa ezizinzile nobuchwepheshe obunengqondo zingahlangabezana nezidingo zokumelana nokugqwala kwemikhiqizo eminingi yethangi eliqinile.Ucwaningo oluhlobene luphinde lwathola ukuthi ukugqwala ethangini leminye imikhiqizo kwenzeka ngaphambili, ngenxa yezinhlobo ezahlukene zokugqwala kanye nendawo okwenzeka kuyo, izinga lokuthuthukiswa kwalo lihluke kakhulu, amanye amathangi aqinile akhiqize izindawo zokugqwala phakathi namasonto ambalwa, sína. ukugqwala ngisho nangemva kwezinyanga ezimbalwa izovela mkhuba ukugqwala perforation, abanye ithangi ukugqwala okuqinile kungaqhubeka ukuphila eshalofini ngemva ukugqwala ngeke kwenzeke ukugqwala perforation.Enqubweni yokukhiqiza nokugcinwa kwamathini e-tinplate, kuvame ukutholakala ukuthi kuzoba nokugqwala kwethangi ngaphambi kokufinyelela impilo yeshalofu yamathini aqinile, futhi amafomu okugqwala amakhulu ahlukaniswe abe ukugqwala okufanayo kanye nokugqwala kwendawo.Ukugqwala kwendawo kuyingozi kwikhwalithi nokuphepha kwethangi, futhi kungaholela ekugqwaleni nasekuvuzeni kokubhoboza ngesikhathi seshalofu lethangi.

1. Ukugqwala okufanayo

Ukugqwala okufanayo, okwaziwa nangokuthi ukugqwala okuphelele, ukugqwala kwasakazwa kuyo yonke indawo yensimbi, izinga lokugqwala lengxenye ngayinye yendawo yensimbi licishe lifane, indawo yensimbi incishiswe ngokulinganayo, futhi ingaphezulu lensimbi alibonakali. umehluko ku-corrosion morphology, ukugqwala okunjalo kulula ukukuthola nokulawula ngoba kwenzeka endaweni yonke.Isimo sokugqwala esivame kakhulu ku-tinplate can ukugqwala ukugqwala okufanayo, okwenzeka kakhulu endaweni yentamo ngaphezulu komzimba wekani, indawo yokuguqulwa engaphansi komzimba wethini kanye nokuma kwendawo yokumboza i-weld.

2. Ukugqwala kwendawo

Ukugqwala kwendawo, okwaziwa nangokuthi ukugqwala okungeyona into efanayo, kubangelwa ukwakheka kokugqwala kwebhethri lendawo ngenxa yokungafani kokusebenza kwe-electrochemical, njengezinsimbi ezingafani, ukonakala kwendawo, umehluko wokugxilisa ingqondo, ukugxilisa ingqondo kwengcindezi noma ukungafana kwendawo ezungezile.I-negative kanye ne-anode yokugqwala kwendawo ingahlukaniswa, ukugqwala kwendawo kugxilwe endaweni ethile, kwenzeka ngokushesha, izinto ezibonakalayo zigqwala ngokushesha, futhi ukugqwala kwendawo ye-tinplate kungaholela kalula entweni yokuvuza kwe-perforation.Ukugqwala kwendawo kuveza izici ezihlukahlukene, ngokohlobo lomonakalo wokugqwala kwendawo, ukugqwala okunjalo kungahlukaniswa kube ukugqwala kukagesi, ukugqwala kwembotshana, ukugqwala komthungo, ukugqwala kwe-intergranular, ukugqwala kokugqoka, ukugqwala kwengcindezi, ukugqwala kokukhathala noma ukugqwala okukhethiwe.

Ukugqwala kwendawo kwamathini e-tinplate kugxile kakhulu endaweni yokushisela noma indandatho yokwandisa yekhava engezansi yethangi, lapho ukugqwala okungaphansi kuyindawo eyinhloko yokugqwala, njengoba kuboniswe esithombeni esingezansi, isikhungo esimnyama. iyunifomu ukugqwala indawo ibonakala izimbobo ukugqwala, uma kuqhathaniswa nendawo ukugqwala umfaniswano, indawo ukugqwala imbobo incane kakhulu, kuyinto evamile wendawo ukugqwala isenzakalo, ukuthuthukiswa okuqhubekayo ukugqwala kuzoholela ethangini ukugqwala perforation.
Ngokuvamile, i-body-welder kanye coater of Changtai Intelligent for can-making imishini，Imishini emihle kakhulu yokuxazulula izinkinga ezingenhla, siyakwamukela ukuthintana nobuchwepheshe bemishini yeNkampani ye-changtai ekuxazululeni le nkinga.
