你知道鋼(gang)結構怎么防(fang)腐嗎？防銹處(chu)理→清理→噴(pen)漆防腐蝕底(di)涂劑→查驗補擦→噴(pen)漆防腐蝕表層。

1.防(fang)銹(xiu)(xiu)(xiu)(xiu)處理加工工藝規定(ding):底層(ceng)完全清(qing)除(chu)，用專業設備(bei)打磨(mo)拋光防(fang)銹(xiu)(xiu)(xiu)(xiu)處理或拋丸(wan)除(chu)銹(xiu)(xiu)(xiu)(xiu)。防(fang)銹(xiu)(xiu)(xiu)(xiu)處理后(hou)(hou)，底層(ceng)不可有銹(xiu)(xiu)(xiu)(xiu)跡(ji)、油漬(zi)、植物油脂、塵(chen)土、鐵沙(sha)和(he)氫氧化物。防(fang)銹(xiu)(xiu)(xiu)(xiu)處理后(hou)(hou)。務必在六小時內噴(pen)底開展防(fang)銹(xiu)(xiu)(xiu)(xiu)解決。噴(pen)漆全過程前(qian)，如(ru)遇降水或別的(de)導(dao)致基材鋼(gang)表(biao)層(ceng)濕冷的(de)狀況，應在自然環境做到(dao)施工條件后(hou)(hou)，用烘干(gan)的(de)壓縮氣體烘干(gan)表(biao)層(ceng)水份，隨(sui)后(hou)(hou)防(fang)銹(xiu)(xiu)(xiu)(xiu)處理；除(chu)銹(xiu)(xiu)(xiu)(xiu)后(hou)(hou)的(de)不銹(xiu)(xiu)(xiu)(xiu)鋼(gang)板(ban)材表(biao)層(ceng)做到(dao)除(chu)銹(xiu)(xiu)(xiu)(xiu)等級Sa2.5，表(biao)層(ceng)僅有用軟毛刷等專用工具清(qing)理后(hou)(hou)才可以完成下一(yi)道工藝流(liu)程。防(fang)銹(xiu)(xiu)(xiu)(xiu)處理后(hou)(hou)的(de)不銹(xiu)(xiu)(xiu)(xiu)鋼(gang)板(ban)材外表(biao)呈金(jin)屬(shu)質感，每平米金(jin)屬(shu)表(biao)層(ceng)的(de)銹(xiu)(xiu)(xiu)(xiu)跡(ji)和(he)漆料不能超過5%。假如(ru)面漆前(qian)早已銹(xiu)(xiu)(xiu)(xiu)蝕(shi)，應再次打磨(mo)拋光或拋丸(wan)除(chu)銹(xiu)(xiu)(xiu)(xiu)，以防(fang)減少(shao)表(biao)面粗糙度。

2.清理(li)技(ji)術規定:選用(yong)高壓清洗設(she)備(bei)，底(di)層外(wai)表務(wu)必(bi)清理(li)整(zheng)潔(jie)，底(di)層間隙、凸凹位置(zhi)和隱(yin)敝角(jiao)務(wu)必(bi)充分清潔(jie)整(zheng)潔(jie)。基(ji)(ji)準(zhun)面務(wu)必(bi)堅固整(zheng)平(ping)(ping)，工程施工前務(wu)必(bi)結(jie)構加固凸凹不平(ping)(ping)或有裂痕的位置(zhi)；基(ji)(ji)準(zhun)面務(wu)必(bi)完全清除(chu)，無污漬、塵土(tu)、臟物、明水、油漬或松散(san)物等(deng)殘渣。，并隨時隨地留意維持基(ji)(ji)準(zhun)面日常(chang)保(bao)潔(jie)。

3.防腐蝕(shi)面漆(qi)加工(gong)(gong)(gong)工(gong)(gong)(gong)藝規定:工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)工(gong)(gong)(gong)前，基(ji)準面務必保證無(wu)鐵銹(xiu)、無(wu)濕(shi)痕、存水、清理，下雨(yu)天(tian)不能(neng)工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)工(gong)(gong)(gong)。選用髙(gao)壓噴(pen)漆(qi)專業設備工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)工(gong)(gong)(gong)，工(gong)(gong)(gong)程(cheng)(cheng)(cheng)材(cai)料(liao)務必膠體沉淀。通過嚴謹(jin)查(cha)驗，涂料(liao)桶蓋(gai)開(kai)啟后盡可(ke)能(neng)當(dang)日應用；噴(pen)漆(qi)原(yuan)材(cai)料(liao)應用前，務必用專用型數控磨(mo)床勻稱(cheng)拌和，保證工(gong)(gong)(gong)程(cheng)(cheng)(cheng)施(shi)工(gong)(gong)(gong)流程(cheng)(cheng)(cheng)中髙(gao)壓噴(pen)漆(qi)專業設備無(wu)堵塞，噴(pen)漆(qi)全過程(cheng)(cheng)(cheng)務必勻稱(cheng)、無(wu)沉積(ji)、無(wu)忽略(lve)。

4.查(cha)驗(yan)補擦:對(dui)于角落里、邊縫(feng)、水準鋼筋(jin)搭(da)接(jie)、豎直鋼筋(jin)搭(da)接(jie)、離心風機出入口、外伸(shen)平屋面管路、中央空調管路、金屬材料板材與圈梁相接(jie)處、螺絲固(gu)定件(墻腳、C型(xing)鋼、H型(xing)鋼、電線(xian)槽、吊頂天花板絲桿、管路)等金屬屋面(墻壁、房間內(nei))防(fang)腐蝕薄弱點。

5.防腐(fu)蝕(shi)(shi)表層(ceng)噴漆(qi)工(gong)(gong)藝(yi)規定(ding)：表層(ceng)噴涂(tu)工(gong)(gong)程(cheng)施(shi)工(gong)(gong)前(qian)需要干(gan)躁，選用(yong)髙壓噴漆(qi)專(zhuan)業設備工(gong)(gong)程(cheng)施(shi)工(gong)(gong)，施(shi)工(gong)(gong)后(hou)(hou)防腐(fu)蝕(shi)(shi)鍍(du)層(ceng)厚薄勻稱，合(he)乎設計規定(ding)；不(bu)可有掉(diao)下來、縫隙沉積(ji)、漲縮(suo)邊沿、汽泡、分(fen)層(ceng)次、合(he)閉(bi)不(bu)嚴實等缺點。工(gong)(gong)程(cheng)施(shi)工(gong)(gong)保(bao)證底層(ceng)總(zong)體(ti)無縫拼接全方位遮蓋(gai)，工(gong)(gong)程(cheng)項目(mu)結束(shu)后(hou)(hou)進(jin)到(dao)維護保(bao)養期，嚴禁(jin)所有人進(jin)到(dao)施(shi)工(gong)(gong)工(gong)(gong)地(di)。
