工(gong)(gong)(gong)業(ye)領域(yu)的(de)小伙(huo)伴對工(gong)(gong)(gong)業(ye)防(fang)腐(fu)(fu)漆應該(gai)不陌生。工(gong)(gong)(gong)業(ye)防(fang)腐(fu)(fu)漆的(de)作(zuo)用是:在(zai)一些工(gong)(gong)(gong)業(ye)場(chang)所(suo)如(ru)水(shui)泥廠(chang)、化工(gong)(gong)(gong)廠(chang)、電廠(chang)等(deng)(deng)領域(yu),由于環境(jing)比較復(fu)雜,常面(mian)對各(ge)類(lei)物(wu)質的(de)腐(fu)(fu)蝕風險(xian),如(ru)酸(suan)堿腐(fu)(fu)蝕、大氣腐(fu)(fu)蝕、化學藥品腐(fu)(fu)蝕,為了保證生產的(de)正常進(jin)行(xing),常需要對工(gong)(gong)(gong)業(ye)區內各(ge)個物(wu)質如(ru)鋼(gang)結構、生產工(gong)(gong)(gong)具、地面(mian)等(deng)(deng)進(jin)行(xing)防(fang)腐(fu)(fu)保護,此時就(jiu)需要用到工(gong)(gong)(gong)業(ye)防(fang)腐(fu)(fu)漆。
工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi)有兩種(zhong)類型,其一是單(dan)組(zu)(zu)(zu)份(fen)工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi),主(zhu)要(yao)包括(kuo)丙烯酸(suan)(suan)工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi)、醇酸(suan)(suan)工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi),其二(er)是雙組(zu)(zu)(zu)份(fen)工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi),主(zhu)要(yao)包括(kuo)環氧工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi),聚(ju)氨(an)酯工(gong)(gong)(gong)業(ye)(ye)防(fang)(fang)腐漆(qi)。單(dan)組(zu)(zu)(zu)份(fen)與雙組(zu)(zu)(zu)份(fen)的區別是單(dan)組(zu)(zu)(zu)份(fen)反(fan)應無需(xu)固化(hua)劑,雙組(zu)(zu)(zu)份(fen)則需(xu)要(yao)固化(hua)劑與基料的交聯反(fan)應,得到所需(xu)結構。
那么(me)工業防腐(fu)漆(qi)該如何使用呢?
拿環(huan)氧(yang)地(di)坪漆舉例(li):
處理(li)基層:清(qing)除基面雜物,對(dui)基面做除塵、除銹處理(li),如出現凹(ao)凸(tu)不平(ping)(ping)處,需磨平(ping)(ping)凸(tu)起填充凹(ao)陷,對(dui)于特殊污(wu)漬(zi)要進行專業處理(li),保持(chi)基面干(gan)凈、平(ping)(ping)整,不起塵不開裂(lie)空(kong)敲(qiao)。
底涂:采用(yong)刷(shua)涂或者(zhe)輥涂的(de)方法涂第一(yi)層(ceng)漆面(mian),施(shi)工時要保(bao)證漆面(mian)均勻薄厚一(yi)致,確保(bao)附著力合(he)格后方可(ke)進行下一(yi)層(ceng)施(shi)工。
中(zhong)涂(tu)與批(pi)涂(tu):將配(pei)好的環氧樹脂漆中(zhong)加(jia)入(ru)石英調(diao)配(pei)好砂(sha)漿,將其均勻地涂(tu)抹在底層(ceng)上。涂(tu)抹完畢使用(yong)砂(sha)紙將涂(tu)層(ceng)打磨平整,無孔洞凸起為合格。
膩子批(pi)補:在批(pi)涂(tu)好的層面上刮涂(tu)中涂(tu)材(cai)料(liao),批(pi)補完畢(bi)后打磨(mo)平整。
面(mian)(mian)涂與養護:面(mian)(mian)涂輥涂兩道環氧地坪涂料,完工(gong)后使層面(mian)(mian)光滑(hua)平整,顏色均勻無空敲。待24小(xiao)時(shi)面(mian)(mian)層實干后,再養護保(bao)養7天后投入使用(yong)。
