【核心提示】十二五時(shí)期,重大科技水專項(xiàng)批共啟動(dòng)實(shí)施了11個(gè)項(xiàng)目,山東省海河水專項(xiàng)被列入其中,這對(duì)建設(shè)生態(tài)山東和打造讓江河湖泊休養(yǎng)生息示范省具有十分重要的意義。記者從重大科技水專項(xiàng)山東省海河水專項(xiàng)(以下簡稱海河水專項(xiàng))啟動(dòng)會(huì)上了解到,十一五期間,山東省南四湖納入重大科技水專項(xiàng),經(jīng)過專家團(tuán)隊(duì)和有關(guān)單位的不懈努力,攻克難題并推廣應(yīng)用了一批治污關(guān)鍵技術(shù),實(shí)現(xiàn)了南四湖流域水環(huán)境質(zhì)量明顯改善。
下面簡單介紹除塵配件涂裝時(shí)需要注意的地方:A.除塵配件的漆膜應(yīng)均勻,顏色一致,不得有發(fā)脆、剝落、裂紋、卷皮和刷痕等缺陷,厚度不得小于5m。B.除塵配件涂裝前應(yīng)將表面的鐵銹、殘留物、油污、塵土及其他臟物清除干凈。除銹方法和除銹等級(jí)應(yīng)符合GB-8923的規(guī)定,當(dāng)使用噴射或拋丸除銹時(shí),其除銹等級(jí)不低于Sa2;當(dāng)使用手刷或動(dòng)力工具除銹時(shí),除銹等級(jí)不低于St2。C.整機(jī)出廠的除塵配件,其外表面均涂底漆兩道、面漆兩道;分體發(fā)運(yùn)現(xiàn)場(chǎng)安裝的大型除塵器,在現(xiàn)場(chǎng)涂后一道面漆。
搪玻璃面的焊縫應(yīng)無明顯的凸起。在這里告訴大家一個(gè)專業(yè)知識(shí),金屬基體凸起部位(也就是外圓弧部位)的搪玻璃層在較高溫度下,由于搪玻璃層和金屬基體熱膨脹系數(shù)的差異,會(huì)受到拉應(yīng)力的作用,而搪玻璃層是脆性材料,抗拉應(yīng)力的性能很差。在金屬基體上盡量減少凸起部位的出現(xiàn),凸起的焊縫應(yīng)盡量磨平。搪玻璃面不應(yīng)有明顯的凹坑。凹坑是修磨鐵胎金屬基體表面的缺陷留下的,凹坑越多,說明所用的鋼板的表面質(zhì)量差,這種鋼板不適宜用于搪玻璃設(shè)備。
