為什么(me)要(yao)對不銹鋼(gang)管(guan)進行酸洗鈍化處理

西安不銹鋼管(guan)的酸洗(xi)(xi)、鈍(dun)化(hua)就(jiu)(jiu)好(hao)比人要洗(xi)(xi)澡。不銹鋼管(guan)經(jing)焊接、熱處(chu)理、鍛造等(deng)高溫加工(gong)后,表(biao)面會產(chan)生(sheng)一層氧化(hua)皮,這就(jiu)(jiu)要通(tong)過酸洗(xi)(xi)的方(fang)法去除。鈍(dun)化(hua)一般(ban)與酸洗(xi)(xi)聯(lian)系在一起,酸洗(xi)(xi)之后必須進(jin)行鈍(dun)化(hua)從而形(xing)成一層保護(hu)膜,這樣可以有(you)效延長設備的使用壽命。

那(nei)么,不銹(xiu)鋼(gang)管(guan)有哪些酸洗鈍化的方法呢?

1浸漬法

用于可放(fang)入酸洗(xi)(xi)槽或鈍化(hua)槽的零部件(jian),但不適于大設備(bei)酸洗(xi)(xi)液(ye)可較(jiao)長時間使用,生產效率較(jiao)高、成本低;大容(rong)積設備(bei)充滿酸液(ye)浸漬耗液(ye)太大。

2涂刷法

適用于大型設備內處(chu)表面(mian)及(ji)局部(bu)處(chu)理物工操作、勞動條(tiao)件(jian)差、酸液無法回收。

3膏劑法

用于安裝或檢修(xiu)現場,尤其(qi)用于焊接(jie)部處理手工操(cao)作(zuo)、勞(lao)動條(tiao)件差(cha)、生產成本高(gao)。

4噴(pen)淋法

適合于(yu)場地固定,封閉環(huan)境(jing)的單一(yi)產品或內部(bu)結構簡單的設(she)備酸洗鈍化,如板材生產線上(shang)的噴淋(lin)酸洗工序,對不(bu)銹鋼化學品船,可用于(yu)液貨(huo)艙(cang)內壁酸洗。

5循環法

用(yong)于大型設備,如換熱器、管(guan)殼處理(li)施工方便,酸(suan)液可(ke)回用(yong),需配管(guan)與(yu)泵連接循環系統。

6電化學法

既可用(yong)于零(ling)部件,又可用(yong)電(dian)刷法對現場(chang)設備表面處理,技術較(jiao)復雜(za),需直流電(dian)源或恒電(dian)位儀(yi)。

當然,不銹鋼管的酸洗鈍化處理也有許(xu)多(duo)需(xu)要注(zhu)意的地方:

酸洗、鈍化前的預處理

1.對(dui)制造(zao)完工(gong)后的不(bu)銹鋼容器或零部件(jian)按圖樣(yang)和工(gong)藝文件(jian)的要求,對(dui)規(gui)定項目檢查合格后,才能進行酸洗(xi)、鈍化預處理。

2.將焊縫及(ji)其兩側焊渣、飛濺物(wu)清(qing)理干(gan)凈,容器的機加工件表面應(ying)用汽油或清(qing)洗劑去除油漬等污物(wu)。

3.**焊縫兩側異物時,應用(yong)不(bu)銹鋼絲刷,不(bu)銹鋼鏟(chan)或砂(sha)輪**,**完畢(bi)用(yong)凈(jing)水(水中(zhong)氯離子含量不(bu)超過25mg/l)沖刷干凈。

4.當油(you)污嚴重(zhong)時則用(yong)3-5%的堿溶液將油污(wu)**,并用凈水沖洗干凈。

5.對(dui)不(bu)銹鋼熱加工件(jian)的氧化皮可(ke)用(yong)機械噴砂(sha)的方(fang)法**,砂(sha)必(bi)須是純硅(gui)或(huo)氧化鋁(lv)。

6.制(zhi)定酸洗、鈍(dun)化的(de)安全措施,確定必須的(de)用(yong)具和勞動(dong)防(fang)護用(yong)品(pin)。

酸洗鈍化操作

只有進行(xing)過預(yu)處理的容器(qi)或零部件才能進行(xing)酸洗鈍化處理。

酸洗液(ye)酸洗主要用(yong)(yong)于較小型未經加工的零(ling)部件整(zheng)體(ti)處理,可以(yi)用(yong)(yong)噴刷的方法(fa)。溶液(ye)溫度(du)在(zai)21-60℃時,每隔(ge)10分鐘左右(you)檢查(cha)一(yi)次,直至呈現出均勻(yun)的白(bai)色酸蝕的光潔度為止。

酸(suan)洗膏酸(suan)洗主要適用于(yu)大型容器(qi)或局(ju)部處(chu)理。在室溫下將酸(suan)洗膏外均勻干凈(jing)設備上(約2-3mm厚),停留(liu)一小(xiao)時(shi)后用潔凈水或不銹鋼絲刷輕輕刷,直至呈現出均勻的白色酸蝕的光潔度為止(zhi)。

鈍(dun)化液主要適(shi)用于小型容(rong)器(qi)或(huo)部件整體處理,可(ke)以采用浸入或(huo)噴刷的(de)方法,當溶液溫度在48-60℃時,每20分鐘檢查一(yi)次,當溶液在21-47℃時,每小時檢查一次,直至表面生成均勻(yun)的鈍化膜為止。

鈍化膏(gao)主(zhu)要(yao)適用于大型容(rong)器(qi)或局部處理,在室溫(wen)下(xia)將鈍化膏(gao)均勻(yun)涂在酸(suan)洗過的容(rong)器(qi)表(biao)面(mian)(約2-3mm),1小時(shi)后檢查(cha),直至表(biao)面生(sheng)成均勻的鈍化膜(mo)為止。

酸洗鈍(dun)化容器或零部件必須用(yong)潔凈水將表面沖(chong)洗干凈,*后用(yong)酸性(xing)石蕊試紙測試沖(chong)洗面的(de)任(ren)何處,使(shi)PH值在6.5-7.5之間,然后擦干或用壓縮空氣吹干。容(rong)器和零部件經酸洗鈍化后(hou)搬運(yun)吊裝及存放時(shi)禁(jin)止磕碰劃傷鈍化膜。
