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 inokuphila okuthile kweshalofu, lapho ithini lingakwazi ukuklama impilo yokugqwala kukhulu kunokuphila kweshalofu kungahlangabezana nezidingo zokukhiqiza, ukuqinisekisa ikhwalithi nokuphepha kokudla nesiphuzo esikhathini sokuphila kweshalofu, i-corrosion margin eningi iyikhwalithi eyeqile, ukwandisa 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, ukugqwala okukhulu ngisho nangemva kwezinyanga ezimbalwa kuzovela i-corrosion perforation phenomenon, enye i-corrosion corrosion eqinile ingaqhubeka ngemuva kokugqwala kwe-corrosion ngemuva kokugqwala kwe-corrosion. 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, isenzakalo sokugqwala sisakazwa kuyo yonke indawo yensimbi, izinga lokugqwala lengxenye ngayinye yendawo yensimbi licishe lifane, ingaphezulu lensimbi lincishiswe ngokulinganayo, futhi indawo yensimbi ayinawo umehluko osobala ku-corrosion morphology, ukugqwala okunjalo ngenxa yokuthi kulula ukuyithola kuyo yonke indawo nokulawula. 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 kwasendaweni kwamathini e-tinplate kugxile kakhulu endaweni yokushisela noma indandatho yokwandisa isembozo esingezansi sethangi, lapho ukugqwala okungaphansi kuyindawo eyinhloko yokugqwala kwe-corrosion, njengoba kuboniswe esithombeni esingezansi, indawo ephakathi nendawo yokugqwala emnyama ibonakala izimbobo zokugqwala, uma kuqhathaniswa nendawo yokugqwala komfaniswano iyindawo encane yokugqwala yendawo, indawo yokugqwala indawo encane kakhulu. ukwenzeka, ukuthuthukiswa okuqhubekayo kokugqwala kuzoholela ekubhobokeni kwe-tank corrosion.
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.
