Tinplate (feem ntau hu ua tinplate)refers to a steel plate with a thin layer of metal tin on the surface. Tinplate is made by rolling low carbon steel into a steel plate about 2mm thick, pickling, cold rolling, electrolytic cleaning annealing, flattening, trimming, and then cleaning, electroplating, soft melting, passivation, oiling, and shearing into a finished tinplate plate. The tin used for tinplate is high-purity tin (Sn>99.8%). Lub tin txheej kuj tuaj yeem siv los ntawm kub dip plating. Lub tin txheej ntawm lub tinplate tau los ntawm txoj kev no yog thicker, tus nqi ntawm cov tin yog loj, thiab tsis muaj kev kho purification yuav tsum tau tom qab tin plating.
Tinplate muaj tsib ntu, los ntawm sab hauv mus rau sab nraud, steel substrate, tin - hlau alloy txheej, tin txheej, oxide zaj duab xis thiab roj zaj duab xis.
Cov txheej txheem ntau lawm ntawm tinplate feem ntau suav nrog electroplating tin, mos melting, cathode passivation thiab oiling. Cov txheej txheem electroplating tinning tso ib txheej ntawm hlau tin rau ntawm cov ntawv txias -rolled. Cov txheej txheem reflow tsim ib lub tin nyias heev - hlau alloy txheej ntawm txias - dov substrate thiab cov ntshiab tin txheej. Txoj kev kho cathode passivation thiab oiling txheej txheem tsim ib zaj duab xis passivation thiab roj zaj duab xis raws li.
Tinplate muaj qhov zoo ntawm qhov tsis muaj ntxhiab, tsis yog - tshuaj lom, lub teeb hauv qhov hnyav, thiab yooj yim rau kev ua thiab cov duab. Kev luam ntawv sib txawv kuj tuaj yeem ua kom zoo nkauj ntawm cov khoom, yog li nws tau siv dav hauv kev lag luam khoom noj khoom haus, khoom siv hluav taws xob, tshuaj pleev xim thiab lwm yam lag luam. Nyob rau hauv cov txheej txheem ntawm tinplate, tom qab lub sawb hlau yog reflowed los ntawm tin plating, thiaj li yuav tiv thaiv cov tin txheej los ntawm oxidizing thiab yellowing thaum lub sij hawm cia los yog xim ci, thiab los txhim kho lub tinplate anti- sulfur zog, tinplate yuav tsum passivated.
