一、如何噴金屬漆
金屬漆噴(pen)(pen)涂(tu)(tu)工藝相(xiang)對(dui)于其它色漆而言復(fu)雜的多,一般(ban)采用空氣噴(pen)(pen)涂(tu)(tu),這種工藝的特點(dian)是:首(shou)先霧噴(pen)(pen)一遍,讓其與中涂(tu)(tu)漆能夠充分結合后(hou),再用正常的方(fang)式噴(pen)(pen)涂(tu)(tu)金屬漆,最后(hou)則是修補金屬漆噴(pen)(pen)涂(tu)(tu)過程中出現的問(wen)題及缺(que)陷(xian)。要在這里注意的是罩(zhao)光(guang)清漆第一遍最好薄噴(pen)(pen),而第二道罩(zhao)光(guang)清漆則是起到裝飾作用,所以(yi)可根據具體(ti)需(xu)求確定噴(pen)(pen)涂(tu)(tu)厚(hou)度(du)。
金屬漆(qi)(qi)的(de)(de)(de)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)方(fang)法(fa)是(shi)(shi)(shi)(shi)什(shen)么?以(yi)(yi)銀粉(fen)色(se)漆(qi)(qi)為例,銀粉(fen)色(se)漆(qi)(qi)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)分(fen)三(san)遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu):第(di)一遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)時(shi)(shi)只(zhi)需(xu)如(ru)(ru)薄霧般的(de)(de)(de)薄噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)即可(ke)(ke)(ke),目的(de)(de)(de)是(shi)(shi)(shi)(shi)使(shi)涂(tu)(tu)(tu)料能與中涂(tu)(tu)(tu)涂(tu)(tu)(tu)膜結合,從而(er)能夠確認(ren)是(shi)(shi)(shi)(shi)否(fou)有(you)魚眼等噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)缺陷的(de)(de)(de)發生(sheng)(sheng),若在這時(shi)(shi)候發現有(you)魚眼缺陷,便(bian)需(xu)要(yao)稍(shao)(shao)微提高些空氣壓力(li),然(ran)(ran)后通過(guo)施工人員的(de)(de)(de)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)技巧(qiao)從而(er)將(jiang)魚眼的(de)(de)(de)缺陷填平。第(di)二遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)則(ze)是(shi)(shi)(shi)(shi)為了(le)遮(zhe)蓋中涂(tu)(tu)(tu)漆(qi)(qi),然(ran)(ran)后顯出(chu)(chu)面(mian)漆(qi)(qi)的(de)(de)(de)顏(yan)色(se)。所以(yi)(yi)基本都使(shi)用(yong)(yong)單程(cheng)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)方(fang)式噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu),當(dang)然(ran)(ran)在此要(yao)注意(yi)在施工途中盡(jin)可(ke)(ke)(ke)能不(bu)要(yao)產生(sheng)(sheng)銀粉(fen)色(se)漆(qi)(qi)的(de)(de)(de)色(se)斑(ban)缺陷,噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)槍的(de)(de)(de)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)速度稍(shao)(shao)快即可(ke)(ke)(ke)。第(di)三(san)遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)則(ze)是(shi)(shi)(shi)(shi)修正第(di)二遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)中的(de)(de)(de)色(se)斑(ban)和噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)不(bu)均,從而(er)凸(tu)顯銀粉(fen)色(se)漆(qi)(qi)的(de)(de)(de)立體感,當(dang)然(ran)(ran)為了(le)防止透明漆(qi)(qi)層(ceng)(ceng)在噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)時(shi)(shi)引起的(de)(de)(de)銀粉(fen)色(se)斑(ban)的(de)(de)(de)作(zuo)用(yong)(yong),所以(yi)(yi)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)槍的(de)(de)(de)運行(xing)速度需(xu)要(yao)稍(shao)(shao)微加快。在噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)完成后,大概15分(fen)鐘便(bian)可(ke)(ke)(ke)使(shi)部分(fen)溶劑揮發,而(er)涂(tu)(tu)(tu)膜也會變(bian)得干燥。這時(shi)(shi)候可(ke)(ke)(ke)以(yi)(yi)用(yong)(yong)手指輕輕觸(chu)及涂(tu)(tu)(tu)面(mian),如(ru)(ru)果不(bu)粘上顏(yan)色(se),那么就(jiu)可(ke)(ke)(ke)以(yi)(yi)進(jin)行(xing)罩(zhao)光漆(qi)(qi)的(de)(de)(de)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)。罩(zhao)光漆(qi)(qi)的(de)(de)(de)第(di)一遍(bian)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)切忌不(bu)可(ke)(ke)(ke)厚(hou)涂(tu)(tu)(tu),以(yi)(yi)稍(shao)(shao)許能出(chu)(chu)現光澤的(de)(de)(de)程(cheng)度噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu),噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)槍的(de)(de)(de)運行(xing)速度比普通稍(shao)(shao)快。若第(di)一遍(bian)就(jiu)采用(yong)(yong)厚(hou)涂(tu)(tu)(tu)的(de)(de)(de)方(fang)式,會使(shi)得已完成的(de)(de)(de)銀粉(fen)漆(qi)(qi)層(ceng)(ceng)崩(beng)潰,也就(jiu)是(shi)(shi)(shi)(shi)引起色(se)斑(ban)。第(di)二遍(bian)罩(zhao)光漆(qi)(qi)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)基本就(jiu)是(shi)(shi)(shi)(shi)純粹(cui)裝飾之(zhi)用(yong)(yong),所以(yi)(yi)要(yao)注意(yi)平坦性重(zhong)疊(die)地(di)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)。如(ru)(ru)果采用(yong)(yong)的(de)(de)(de)是(shi)(shi)(shi)(shi)雙程(cheng)噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)涂(tu)(tu)(tu)方(fang)法(fa),那么噴(pen)(pen)(pen)(pen)(pen)(pen)(pen)(pen)槍在運行(xing)當(dang)中,需(xu)要(yao)保(bao)證正常或稍(shao)(shao)慢速度即可(ke)(ke)(ke)。
二、金屬漆噴涂的注意事項
1、噴涂(tu)金屬漆后,在下一次(ci)操作之前必須除塵。
2、金屬漆(qi)主要起到覆蓋作用(yong),切勿噴(pen)涂過(guo)(guo)厚,否則漆(qi)面(mian)顏色會過(guo)(guo)暗過(guo)(guo)深。
3、攪(jiao)拌要均勻。金屬(shu)漆(qi)中的(de)鋁粉等金屬(shu)顆粒容易沉(chen)淀在(zai)油漆(qi)罐底,所以金屬(shu)漆(qi)比一般本(ben)色漆(qi)在(zai)噴涂之前更需要經過(guo)徹底的(de)攪(jiao)拌。
4、必(bi)須根據(ju)油漆(qi)(qi)廠商提供的(de)說明書來選擇配套的(de)稀(xi)釋劑和(he)相應的(de)稀(xi)釋比例,并應正確(que)使用黏(nian)(nian)度計,掌握所需的(de)黏(nian)(nian)度,以確(que)保漆(qi)(qi)面顏色符合要求。
5、噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)的使用。噴(pen)(pen)(pen)(pen)涂(tu)(tu)金屬漆(qi)時,均(jun)勻(yun)的漆(qi)膜(mo)厚(hou)度(du)是非常(chang)重要(yao)的。噴(pen)(pen)(pen)(pen)嘴應(ying)以垂(chui)直(zhi)角度(du)對準噴(pen)(pen)(pen)(pen)涂(tu)(tu)表面(mian),二者(zhe)之間(jian)的距離(li)應(ying)保持在5~20cm之間(jian),以勻(yun)速(su)直(zhi)線(xian)移動(dong)噴(pen)(pen)(pen)(pen)槍(qiang)(qiang),避免以弧(hu)型的方式移動(dong)噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)。每次(ci)往(wang)復噴(pen)(pen)(pen)(pen)涂(tu)(tu)需要(yao)50%的重疊區域,這(zhe)樣能獲(huo)得固(gu)定的顏色(se)。需要(yao)調整(zheng)噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)的出漆(qi)量時,可以將噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)扳機扣到(dao)底,用噴(pen)(pen)(pen)(pen)槍(qiang)(qiang)移動(dong)的速(su)度(du)來增(zeng)加或降低漆(qi)膜(mo)的厚(hou)度(du)和干燥程度(du)。
三、車用金屬漆的保養
汽車(che)金(jin)(jin)屬(shu)(shu)漆(qi)的主要成分是(shi)鋁粉,它更(geng)(geng)容易(yi)氧化(hua),并(bing)且容易(yi)龜裂,因此更(geng)(geng)需(xu)要定(ding)時進(jin)行(xing)維護保養(yang),汽車(che)金(jin)(jin)屬(shu)(shu)漆(qi)的保養(yang)有(you)以下幾個步驟:
1、清洗(xi)要(yao)保持金(jin)屬漆(qi)的外表干(gan)凈,僅(jin)靠擦一擦灰(hui)塵是(shi)不夠的,要(yao)注意(yi)經常(chang)和及時地清洗(xi)車(che)輛。
2、打蠟(la)(la)(la)要保持金屬漆的容(rong)貌,打蠟(la)(la)(la)是(shi)不可少的。但是(shi)頻繁打蠟(la)(la)(la)、干脆不打蠟(la)(la)(la)以及迷信進口的蠟(la)(la)(la),其實(shi)都是(shi)不妥當的。由于各種(zhong)車(che)(che)(che)蠟(la)(la)(la)的性能(neng)不同(tong),其作(zuo)用與效(xiao)果也不一樣,所以在選用時(shi)必(bi)須(xu)慎重(zhong)。選擇不當不僅不能(neng)保護車(che)(che)(che)身,反而會使車(che)(che)(che)漆變色(se)(se)。一般情況(kuang)下(xia),應根(gen)據(ju)車(che)(che)(che)蠟(la)(la)(la)的作(zuo)用、特點,車(che)(che)(che)輛的新舊程度、車(che)(che)(che)漆顏色(se)(se)及車(che)(che)(che)輛的行(xing)駛環境等因素綜合考慮。
3、修(xiu)補專(zhuan)業的劃痕(hen)修(xiu)補對作(zuo)業環境(jing)有嚴格要求(qiu),因(yin)為噴(pen)漆最(zui)怕的就是灰(hui)塵(chen)和雜質的影(ying)響(xiang)。如(ru)果灰(hui)塵(chen)、操作(zuo)工(gong)人的頭屑或(huo)衣(yi)服(fu)上的纖維落(luo)在車身外表面上,都會(hui)形成斑(ban)點或(huo)鼓包。
4、維(wei)護對外(wai)表(biao)噴(pen)涂油漆(qi)的塑(su)料件(jian),應(ying)使用優(you)質的清潔(jie)劑(ji)進行清潔(jie);上(shang)蠟(la)時(shi)不能用力過重,防(fang)止穿透油漆(qi)露出底(di)色。
