烤漆鐵桶在烘(hong)烤中應注意(yi)哪些問題？

在(zai)金屬包(bao)裝中，絕大多數是采用對馬口鐵的涂布，印刷后再進行烘烤(kao)處(chu)理(li)然(ran)后制造(zao)。不(bu)同類型(xing)的產品(pin)，數烤(kao)漆桶是不(bu)需要(yao)處(chu)理(li)，直接加工成型(xing)的。因為金屬薄鋼板(ban)、鍍錫等在(zai)溫度(du)較(jiao)大時(shi)會影(ying)響盛裝食品(pin)，對人體有害，所以在(zai)盛裝食品(pin)時(shi)必須要(yao)求防銹(xiu)、防腐蝕(shi)、防酸性、防漏透的高阻隔層來達到上述要(yao)求。

不論是(shi)盛(sheng)裝食品(pin)、飲料(liao)還是(shi)兒童(tong)玩具、筆盒等(deng)都應按要(yao)求進行生產(chan)(chan)。這就要(yao)求每個(ge)印鐵制罐(guan)廠在涂料(liao)、涂布、烘烤、制件中(zhong)掌握好每個(ge)環節，才(cai)能(neng)生產(chan)(chan)出合(he)格產(chan)(chan)品(pin)。

烘(hong)烤(kao)時的質(zhi)(zhi)量好(hao)與次(ci)直接影響(xiang)后(hou)加(jia)工的質(zhi)(zhi)量和(he)加(jia)工后(hou)的盛(sheng)裝食(shi)品所帶來的各種質(zhi)(zhi)量問(wen)題。因此，涂料鐵(tie)在(zai)進行烘(hong)烤(kao)時起(qi)到了很重(zhong)要的作用。

鍍鋅鐵桶縫焊的要求

在制作鍍(du)鋅(xin)鐵桶時，要使鍍(du)鋅(xin)鋼板不進行酸洗、磨(mo)削，而直接通過(guo)拋光后進行點焊和縫焊，開口鐵桶，必須做到下列幾點：

1、點(dian)焊(han)(han)(han)(han)、縫(feng)焊(han)(han)(han)(han)處的油(you)污必須(xu)(xu)拋光(guang)干凈； ??2、點(dian)焊(han)(han)(han)(han)時的焊(han)(han)(han)(han)接(jie)電(dian)流(liu)比(bi)點(dian)焊(han)(han)(han)(han)普(pu)通低(di)碳鋼(gang)(gang)鋼(gang)(gang)板時的焊(han)(han)(han)(han)接(jie)電(dian)流(liu)要提高28%； ??3、點(dian)焊(han)(han)(han)(han)時的電(dian)極壓力(li)比(bi)點(dian)焊(han)(han)(han)(han)普(pu)通低(di)碳鋼(gang)(gang)鋼(gang)(gang)板時的電(dian)極壓力(li)要增大22%； ??4、縫(feng)焊(han)(han)(han)(han)時的焊(han)(han)(han)(han)接(jie)電(dian)流(liu)、焊(han)(han)(han)(han)接(jie)速(su)度與(yu)焊(han)(han)(han)(han)接(jie)普(pu)通低(di)碳鋼(gang)(gang)鋼(gang)(gang)板時相同(tong)； ??5、縫(feng)焊(han)(han)(han)(han)時的電(dian)極壓力(li)比(bi)焊(han)(han)(han)(han)接(jie)普(pu)通低(di)碳鋼(gang)(gang)鋼(gang)(gang)板時的電(dian)極壓力(li)要提高7%； ??6、縫(feng)焊(han)(han)(han)(han)時，除(chu)設備內冷(leng)卻外，泰州鐵桶，必須(xu)(xu)強行施加外部冷(leng)卻水冷(leng)卻被(bei)焊(han)(han)(han)(han)的鐵桶桶身。

鐵桶原輔材料問題

1、鋼(gang)板的(de)(de)材(cai)質(zhi) 材(cai)料含碳量高(gao)，雜(za)質(zhi)超(chao)標(biao)，材(cai)料硬度(du)高(gao)，容(rong)易(yi)脆裂(lie)。桶(tong)身(shen)(shen)翻邊(bian)外、桶(tong)身(shen)(shen)脹(zhang)筋(jin)處、卷邊(bian)處、桶(tong)底頂底部(bu)邊(bian)緣處、桶(tong)頂沖孔(kong)翻邊(bian)處，均易(yi)出現脆裂(lie)。卷圓會出現忽大忽小現象，影響縫焊定位。 2、鋼(gang)板的(de)(de)厚(hou)度(du)超(chao)差 材(cai)料厚(hou)度(du)超(chao)差，20升鐵(tie)桶(tong)，薄厚(hou)不均，卷圓直徑(jing)不均、縫焊機參數(shu)難以適(shi)應、卷封(feng)滾(gun)輪槽形尺寸難以適(shi)應。 3、密封(feng)膠的(de)(de)適(shi)用性(xing) 密封(feng)膠的(de)(de)化學(xue)性(xing)質(zhi)與(yu)盛裝(zhuang)貨(huo)(huo)物(wu)(wu)不適(shi)應，易(yi)發現滲漏現象，或(huo)致貨(huo)(huo)物(wu)(wu)變質(zhi)。 4、封(feng)閉器(qi)密封(feng)圈的(de)(de)質(zhi)量和適(shi)用性(xing) 封(feng)閉器(qi)密封(feng)圈的(de)(de)化學(xue)性(xing)質(zhi)與(yu)盛裝(zhuang)的(de)(de)貨(huo)(huo)物(wu)(wu)不相適(shi)應，易(yi)使(shi)密封(feng)失敗，或(huo)致貨(huo)(huo)物(wu)(wu)變質(zhi)。
