 控(kong)制(zhi)器：靜電(dian)(dian)噴塑(su)設備控(kong)制(zhi)器包括靜電(dian)(dian)發生器，電(dian)(dian)源控(kong)制(zhi)器、供粉(fen)控(kong)制(zhi)器等各控(kong)制(zhi)單元，靜電(dian)(dian)發生器彩(cai)光(guang)柵顯示電(dian)(dian)壓、電(dian)(dian)流，電(dian)(dian)路具有短(duan)路保護，恒流源控(kong)制(zhi)，全部(bu)采(cai)用進口電(dian)(dian)路，采(cai)用了低壓輸入噴槍，使得控(kong)制(zhi)系統更(geng)安全。

金屬(shu)階梯防腐涂層的優勢及制(zhi)作技巧

水工(gong)(gong)鋼結構的(de)使(shi)用(yong)增加(jia)，新型的(de)水工(gong)(gong)鋼結構防腐(fu)技(ji)術(shu)對降低(di)工(gong)(gong)程(cheng)造價、延長工(gong)(gong)程(cheng)壽(shou)命十(shi)分重(zhong)要(yao)，將各種金(jin)屬(shu)涂(tu)層(ceng)優勢互補的(de)金(jin)屬(shu)熱(re)噴涂(tu)金(jin)屬(shu)階梯(ti)涂(tu)層(ceng)運(yun)用(yong)到水工(gong)(gong)鋼結構中，成為金(jin)屬(shu)防腐(fu)新技(ji)術(shu)。

金屬熱噴(pen)(pen)涂(tu)是在(zai)同(tong)一工件(jian)(jian)基(ji)體上疊加(jia)噴(pen)(pen)涂(tu)，先用(yong)鋅涂(tu)層(ceng)作(zuo)為底層(ceng)，再用(yong)不銹(xiu)鋼(gang)涂(tu)層(ceng)作(zuo)為面(mian)層(ceng)，最(zui)終形(xing)(xing)成階梯涂(tu)層(ceng)，運用(yong)到水工鋼(gang)結構中既經濟、又滿意的(de)(de)(de)防(fang)腐效果。其原(yuan)理是利用(yong)某種形(xing)(xing)式的(de)(de)(de)熱源(yuan)將(jiang)金屬噴(pen)(pen)涂(tu)材(cai)料加(jia)熱，使(shi)之形(xing)(xing)成熔融狀態(tai)的(de)(de)(de)微粒(li)，這(zhe)些(xie)微粒(li)在(zai)動力(li)的(de)(de)(de)作(zuo)用(yong)下以一定的(de)(de)(de)速度沖擊并沉附在(zai)基(ji)體表面(mian)上，形(xing)(xing)成具有一定特性(xing)的(de)(de)(de)金屬涂(tu)層(ceng)。水工鋼(gang)結構件(jian)(jian)等基(ji)體材(cai)料的(de)(de)(de)表面(mian)經過熱噴(pen)(pen)涂(tu)技術處理，得(de)到了耐腐蝕(shi)(shi)、耐磨蝕(shi)(shi)的(de)(de)(de)金屬保護涂(tu)層(ceng)，從而增強水工鋼(gang)結構件(jian)(jian)耐腐、耐磨的(de)(de)(de)性(xing)能。

用(yong)于金屬噴涂(tu)(tu)的材料(liao)較多，如鋅(xin)、不(bu)銹(xiu)(xiu)鋼(gang)等(deng)。其中不(bu)銹(xiu)(xiu)鋼(gang)涂(tu)(tu)層(ceng)具有(you)(you)耐磨損及(ji)保護周期長等(deng)特(te)點(dian)；鋅(xin)涂(tu)(tu)層(ceng)不(bu)僅具有(you)(you)覆(fu)蓋、耐腐蝕作用(yong)，更重(zhong)要(yao)的是(shi)具有(you)(you)陰(yin)極保護功能。是(shi)水工(gong)鋼(gang)結構(gou)防腐噴涂(tu)(tu)的重(zhong)要(yao)材料(liao)廣泛應用(yong)。

熱噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)金屬階梯涂(tu)(tu)(tu)(tu)(tu)層(ceng)的工藝流(liu)程分(fen)4個環(huan)節。一是(shi)鋼結構表面處理，二是(shi)熱噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)鋅，三是(shi)噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)不銹鋼，四是(shi)涂(tu)(tu)(tu)(tu)(tu)裝(zhuang)環(huan)氧(yang)云(yun)鐵。涂(tu)(tu)(tu)(tu)(tu)裝(zhuang)環(huan)氧(yang)云(yun)鐵采用手工刷(shua)(shua)涂(tu)(tu)(tu)(tu)(tu)結合空氣噴(pen)(pen)涂(tu)(tu)(tu)(tu)(tu)方法，要求(qiu)無刷(shua)(shua)痕、無起泡、無流(liu)掛、無漏噴(pen)(pen)，銀灰(hui)色外(wai)觀整(zheng)潔(jie)、勻(yun)稱。

階(jie)梯涂(tu)(tu)層(ceng)(ceng)(ceng)底層(ceng)(ceng)(ceng)做(zuo)到(dao)了鋅(xin)層(ceng)(ceng)(ceng)顆粒(li)(li)細(xi)、孔(kong)隙小、涂(tu)(tu)層(ceng)(ceng)(ceng)均(jun)勻、密(mi)實性(xing)好，鋅(xin)層(ceng)(ceng)(ceng)厚(hou)度達(da)到(dao)設計要求。由于鋅(xin)層(ceng)(ceng)(ceng)的(de)(de)厚(hou)度僅為(wei)原(yuan)(yuan)來的(de)(de)一(yi)半而使附著力變得很強，不(bu)(bu)銹鋼涂(tu)(tu)層(ceng)(ceng)(ceng)覆蓋其(qi)上呈灰黑色并(bing)呈顆粒(li)(li)較(jiao)粗、孔(kong)隙較(jiao)大(da)，但(dan)堅硬、耐磨(mo)。因疊加噴涂(tu)(tu)厚(hou)度僅是(shi)原(yuan)(yuan)來的(de)(de)一(yi)半故附著力也好，對鋅(xin)層(ceng)(ceng)(ceng)有很好的(de)(de)保護(hu)作用(yong)(yong)。施工(gong)最后采(cai)用(yong)(yong)環氧云鐵涂(tu)(tu)料封閉，用(yong)(yong)氯(lv)化橡膠鋁粉漆作面漆，防水(shui)、防滲性(xing)能好。熱噴涂(tu)(tu)金屬階(jie)梯涂(tu)(tu)層(ceng)(ceng)(ceng)質量優良、滿(man)足(zu)設計要求，與常用(yong)(yong)噴涂(tu)(tu)技(ji)術的(de)(de)對比，該技(ji)術具有明顯的(de)(de)綜合優勢。熱噴涂(tu)(tu)金屬階(jie)梯涂(tu)(tu)層(ceng)(ceng)(ceng)防腐(fu)技(ji)術涂(tu)(tu)層(ceng)(ceng)(ceng)耐磨(mo)損，外觀整(zheng)潔，覆蓋均(jun)勻、密(mi)實，保護(hu)周期長，防腐(fu)性(xing)能好，抗破壞性(xing)強，不(bu)(bu)需組(zu)織(zhi)二次施工(gong)，是(shi)首選的(de)(de)水(shui)工(gong)鋼結構(gou)防腐(fu)技(ji)術。熱噴涂(tu)(tu)金屬階(jie)梯涂(tu)(tu)層(ceng)(ceng)(ceng)防腐(fu)技(ji)術經濟(ji)、實用(yong)(yong)，又能達(da)到(dao)預期的(de)(de)效果。
