熱(re)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)和(he)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)在(zai)鍍(du)(du)鋅(xin)(xin)(xin)(xin)量上有很大(da)的(de)(de)(de)(de)差別，就像山東(dong)彩涂卷）。熱(re)鍍(du)(du)鋅(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)量不(bu)可(ke)能太小(xiao)，一般(ban)較(jiao)(jiao)小(xiao)為雙(shuang)面50～60g／m2，較(jiao)(jiao)大(da)可(ke)達600g／m2。電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)層(ceng)可(ke)以很薄，較(jiao)(jiao)小(xiao)達15g／m2，但要(yao)求鍍(du)(du)層(ceng)較(jiao)(jiao)厚的(de)(de)(de)(de)話則生(sheng)產線速度很慢(man)，不(bu)適(shi)應現代化機組的(de)(de)(de)(de)工藝特點，一般(ban)較(jiao)(jiao)大(da)為lO0g／m2左右。正因(yin)為如此，電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)生(sheng)產受到很大(da)的(de)(de)(de)(de)限制。工一般(ban)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)比較(jiao)(jiao)多，適(shi)用(yong)于(yu)小(xiao)部件；熱(re)鍍(du)(du)鋅(xin)(xin)(xin)(xin)一般(ban)用(yong)于(yu)電(dian)(dian)力設備(bei)和(he)構件，適(shi)用(yong)于(yu)大(da)的(de)(de)(de)(de)部件和(he)設備(bei)。當然他們的(de)(de)(de)(de)價格(ge)也相(xiang)對便宜一些(xie)。建(jian)設部已正式下(xia)文(wen)，淘汰(tai)技術(shu)落(luo)后的(de)(de)(de)(de)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管，不(bu)準用(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)管作水、煤氣管。

熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)將薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸入熔解的(de)(de)鋅(xin)(xin)槽中，使其(qi)表(biao)面(mian)(mian)粘(zhan)附一層(ceng)鋅(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目(mu)前主要采(cai)用連續鍍(du)(du)(du)鋅(xin)(xin)工藝生(sheng)產(chan)，即把(ba)成卷(juan)的(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連續浸在(zai)熔解有(you)鋅(xin)(xin)的(de)(de)鍍(du)(du)(du)槽中制(zhi)成鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban);合金化鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)也是用熱(re)(re)浸法制(zhi)造，但在(zai)出槽后，立即把(ba)它加(jia)熱(re)(re)到(dao)500 ℃左右，使其(qi)生(sheng)成鋅(xin)(xin)和鐵的(de)(de)合金被膜。這(zhe)種鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具(ju)(ju)有(you)良好的(de)(de)涂(tu)(tu)料的(de)(de)密著性(xing)(xing)和焊接(jie)性(xing)(xing);電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。用電鍍(du)(du)(du)法制(zhi)造這(zhe)種鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)具(ju)(ju)有(you)良好的(de)(de)加(jia)工性(xing)(xing)。但鍍(du)(du)(du)層(ceng)較薄(bo)，耐腐蝕性(xing)(xing)不如熱(re)(re)浸法鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban);單面(mian)(mian)鍍(du)(du)(du)和雙(shuang)面(mian)(mian)差鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。單面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)，即只在(zai)一面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)的(de)(de)產(chan)品。在(zai)焊接(jie)、涂(tu)(tu)裝(zhuang)、防銹處理、加(jia)工等方面(mian)(mian)，具(ju)(ju)有(you)比雙(shuang)面(mian)(mian)鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)好的(de)(de)適應性(xing)(xing)。

鍍鋅鋼管廠家鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。珠海鍍鋅鋼管電鍍鋅成本低，表面不(bu)(bu)是很(hen)光滑(hua)，其(qi)本身的(de)(de)耐(nai)腐(fu)蝕(shi)性(xing)(xing)比熱鍍鋅管相差很(hen)多。提起鍍鋅管，可能沒接觸過(guo)建材(cai)的(de)(de)朋(peng)友(you)并不(bu)(bu)了解。從(cong)1935年建立(li)一條(tiao)連續涂層鋼(gang)(gang)板線開始，彩涂板得到(dao)了廣(guang)泛應(ying)用，目(mu)前(qian)彩涂板的(de)(de)品種繁多，大(da)約超過(guo)600種，彩涂板兼有(you)機聚(ju)(ju)合物與鋼(gang)(gang)板兩者的(de)(de)優點，既有(you)有(you)機聚(ju)(ju)合物的(de)(de)良好著色(se)性(xing)(xing)、成型(xing)性(xing)(xing)、耐(nai)蝕(shi)性(xing)(xing)、裝飾性(xing)(xing)、又有(you)鋼(gang)(gang)板的(de)(de)高強度和易加工性(xing)(xing)，能很(hen)容易地進行沖(chong)壓裁剪、彎(wan)曲、深沖(chong)等(deng)加工。

鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)(dai)鋼(gang)(gang)的(de)鋅(xin)(xin)(xin)(xin)層(ceng)特性 電鍍(du)鋅(xin)(xin)(xin)(xin)層(ceng)是(shi)不能形成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)花的(de)，熱(re)鍍(du)鋅(xin)(xin)(xin)(xin)層(ceng)則有鋅(xin)(xin)(xin)(xin)花，其(qi)形成(cheng)(cheng)過程如下：當(dang)鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)(dai)從(cong)鋅(xin)(xin)(xin)(xin)鍋(guo)(guo)出來(lai)后，經氣刀的(de)噴(pen)吹(chui)，大量鋅(xin)(xin)(xin)(xin)液(ye)(ye)被吹(chui)回鋅(xin)(xin)(xin)(xin)鍋(guo)(guo)，這時帶(dai)(dai)鋼(gang)(gang)表(biao)面還有純鋅(xin)(xin)(xin)(xin)層(ceng)，呈(cheng)液(ye)(ye) 態附在(zai)鋼(gang)(gang)板表(biao)面，在(zai)鋼(gang)(gang)板表(biao)面形成(cheng)(cheng)大量結(jie)晶(jing)核(he)，隨(sui)著(zhu)(zhu)鋼(gang)(gang)板上(shang)升冷卻，使結(jie)晶(jing)核(he)慢慢長成(cheng)(cheng)鋅(xin)(xin)(xin)(xin)花。冷卻速度(du)越快鋅(xin)(xin)(xin)(xin)花越小，冷卻速度(du)越慢鋅(xin)(xin)(xin)(xin)花越大。熱(re)鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)(dai)鋼(gang)(gang)在(zai)我國市場一直(zhi)是(shi)緊缺品(pin)種。從(cong)20世紀90年代中期以來(lai)，每年都要從(cong)國外進口80-100萬t左右。隨(sui)著(zhu)(zhu)國內(nei)經濟的(de)發展(zhan)(zhan)，尤其(qi)是(shi)汽車、家電及建筑業的(de)發展(zhan)(zhan)，對(dui)鍍(du)鋅(xin)(xin)(xin)(xin)帶(dai)(dai)鋼(gang)(gang)的(de)需(xu)求量也大大增加。
