提到鍍鋅圓好的消防排煙風管法蘭我想有很多人都會一臉的茫然，聽說過角鐵圓法蘭，但是就是沒有聽過鍍鋅圓法蘭。那么鍍消防排煙風管定制鋅圓(yuan)法蘭到底是(shi)什么(me)呢？其(qi)實鍍鋅圓(yuan)法蘭比普通(tong)的(de)法蘭就多了一(yi)道鍍鋅的(de)工(gong)序(xu)，但千萬不要小看這一(yi)道鍍鋅的(de)工(gong)序(xu)。

五、建(jian)(jian)議配備排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)機(ji) 對于(yu)油(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)較(jiao)(jiao)(jiao)大的(de)(de)廚(chu)房，建(jian)(jian)議還配備一(yi)(yi)個(ge)(ge)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)機(ji)。常(chang)用(yong)(yong)(yong)的(de)(de)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)風(feng)機(ji)有軸流(liu)風(feng)機(ji)、風(feng)機(ji)箱(xiang)和離(li)心(xin)風(feng)機(ji)3種。 軸流(liu)風(feng)機(ji)：以(yi)前應用(yong)(yong)(yong)較(jiao)(jiao)(jiao)多，但由于(yu)全(quan)壓小(xiao)(xiao)，在(zai)(zai)(zai)(zai)安裝油(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)凈化器后(hou)很少應用(yong)(yong)(yong)。 風(feng)機(ji)箱(xiang)：全(quan)壓中等，風(feng)量(liang)可以(yi)調(diao)節(jie)，且噪聲較(jiao)(jiao)(jiao)低(di)(di)，常(chang)在(zai)(zai)(zai)(zai)集(ji)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)罩距油(you)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)排(pai)(pai)(pai)(pai)(pai)(pai)(pai)放口距離(li)中等的(de)(de)廚(chu)房排(pai)(pai)(pai)(pai)(pai)(pai)(pai)煙(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)(yan)系統(tong)(tong)中選用(yong)(yong)(yong)。 離(li)心(xin)風(feng)機(ji)：全(quan)壓和風(feng)量(liang)都可以(yi)調(diao)節(jie)，但由于(yu)噪聲較(jiao)(jiao)(jiao)大，常(chang)需(xu)要(yao)做降(jiang)噪處理。當(dang)廚(chu)房位于(yu)建(jian)(jian)筑(zhu)物(wu)的(de)(de)底部(bu)(bu)時(shi)其排(pai)(pai)(pai)(pai)(pai)(pai)(pai)風(feng)機(ji)宜安放在(zai)(zai)(zai)(zai)屋(wu)頂，一(yi)(yi)般選擇離(li)心(xin)風(feng)機(ji)。

鍍鋅圓好的消防排煙風管法蘭工藝流程：成品酸洗-水洗-加助鍍液-烘干-掛鍍-冷卻-藥化-清洗-打磨-熱鍍鋅完工 鍍鋅圓法蘭工消防排煙風管定制藝(yi)原理：將鐵件清洗(xi)干凈，然后(hou)溶劑處理，烘干后(hou)浸入鋅(xin)液中(zhong)，鐵與熔融鋅(xin)反應生成(cheng)一合(he)金(jin)化的鋅(xin)層，其流程(cheng)為(wei)：脫脂--水洗(xi)--酸洗(xi)--助鍍(du)--烘干--熱(re)浸鍍(du)鋅(xin)--分(fen)離--冷卻鈍化。

熱鍍鋅的合金層好的消防排煙風管的厚度主要取決了鋼材的硅含量等化學成份，鋼材的橫截面積大小，鋼材表面的消防排煙風管定制粗糙程(cheng)度(du)，鋅(xin)(xin)鍋溫度(du)，浸(jin)鋅(xin)(xin)時(shi)(shi)間，冷(leng)卻快慢，冷(leng)軋變形等。 鍍(du)(du)(du)(du)鋅(xin)(xin)圓法蘭優點： 1、 處理(li)費用低(di)：熱(re)浸(jin)鍍(du)(du)(du)(du)鋅(xin)(xin)防(fang)(fang)銹的費用要(yao)比(bi)其他漆料涂層(ceng)(ceng)的費用低(di)； 2、 持(chi)久(jiu)耐用：在(zai)郊區環(huan)境(jing)下，標準的熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)防(fang)(fang)銹的厚度(du)，可保(bao)持(chi)50年以上(shang)而不必修補；在(zai)市區或近海(hai)區域，標準的熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)防(fang)(fang)銹層(ceng)(ceng)則可保(bao)持(chi)20年而不必修補； 3、 可靠(kao)性好：鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)(ceng)與鋼(gang)材間是冶(ye)金結(jie)合，成為(wei)鋼(gang)表面(mian)的一部份，因此鍍(du)(du)(du)(du)層(ceng)(ceng)的持(chi)久(jiu)性較(jiao)為(wei)可靠(kao)； 4、 鍍(du)(du)(du)(du)層(ceng)(ceng)的韌性強：鍍(du)(du)(du)(du)鋅(xin)(xin)層(ceng)(ceng)形成一種特(te)別的冶(ye)金結(jie)構(gou)，這種結(jie)構(gou)能(neng)承受在(zai)運送(song)及使(shi)用時(shi)(shi)受到機械損傷； 5、 全面(mian)性保(bao)護：鍍(du)(du)(du)(du)件(jian)的每一部分都(dou)能(neng)鍍(du)(du)(du)(du)上(shang)鋅(xin)(xin)，即使(shi)在(zai)凹陷處、尖角(jiao)及隱藏處都(dou)能(neng)全面(mian)地受到保(bao)護； 6、 省(sheng)時(shi)(shi)省(sheng)力：鍍(du)(du)(du)(du)鋅(xin)(xin)過程(cheng)要(yao)比(bi)其他涂層(ceng)(ceng)的施工(gong)法更快捷，并(bing)且可避免安裝后在(zai)工(gong)地上(shang)涂刷(shua)所需的時(shi)(shi)間。
