西安噴(pen)(pen)塑(su)(su) 用(yong)熱固(gu)化(hua)的(de)(de)方法將采用(yong)特殊手段涂在(zai)物(wu)體表面的(de)(de)熱固(gu)性高分(fen)子(zi)樹(shu)脂粉(fen)末溶融,并固(gu)化(hua)成(cheng)(cheng)一層(ceng)塑(su)(su)膜(mo)的(de)(de)工(gong)藝(yi)稱為(wei)噴(pen)(pen)塑(su)(su)。噴(pen)(pen)塑(su)(su)的(de)(de)方式有多種(zhong),.常用(yong)的(de)(de)為(wei)靜電(dian)噴(pen)(pen)涂法。即:將予處(chu)理過的(de)(de)鐵藝(yi)制品接地(di),噴(pen)(pen)槍(qiang)頭(tou)部金屬導流杯接高壓負極霉德(ji),在(zai)兩者(zhe)之(zhi)間形(xing)成(cheng)(cheng)高壓靜電(dian)電(dian)場(chang)。熱固(gu)性高分(fen)子(zi)樹(shu)脂粉(fen)末在(zai)壓縮空氣的(de)(de)作用(yong)下,由供粉(fen)機構經(jing)由噴(pen)(pen)槍(qiang)噴(pen)(pen)出的(de)(de)同帶上了(le)負電(dian)核,因(yin)而(er)吸(xi)附于鐵藝(yi)制品表面。然后,將吸(xi)附有樹(shu)脂粉(fen)末的(de)(de)制品經(jing)一定(ding)溫度,使原來(lai)松散的(de)(de)高分(fen)子(zi)樹(shu)脂粉(fen)末熔融流平,固(gu)化(hua)成(cheng)(cheng)膜(mo)后便形(xing)成(cheng)(cheng)均(jun)勻、連續(xu)、平整的(de)(de)塑(su)(su)質涂層(ceng)。
西安噴(pen)(pen)(pen)(pen蟋滴)漆(qi)(qi)(qi)(qi)(qi) 用(yong)專用(yong)噴殊者(pen)(pen)(pen)(pen)漆(qi)(qi)(qi)(qi)(qi)槍(qiang)作為工(gong)具,以壓縮空氣為送漆(qi)(qi)(qi)(qi)(qi)汽(qi)流(liu),將(jiang)油漆(qi)(qi)(qi)(qi)(qi)從噴(pen)(pen)(pen)(pen)槍(qiang)的(de)噴(pen)(pen)(pen)(pen)咀(ju)中噴(pen)(pen)(pen)(pen)成均(jun)勻(yun)(yun)霧(wu)狀液體(ti),均(jun)勻(yun)(yun)分散沉積(ji)在物(wu)體(ti)表面(mian)稱為噴(pen)(pen)(pen)(pen)漆(qi)(qi)(qi)(qi)(qi)。噴(pen)(pen)(pen)(pen)漆(qi)(qi)(qi)(qi)(qi)的(de)特點是(shi):漆(qi)(qi)(qi)(qi)(qi)膜(mo)薄(bo)而均(jun)勻(yun)(yun)、光滑平(ping)整,各種部位都能噴(pen)(pen)(pen)(pen)到,不出死角(jiao)(jiao),施工(gong)效率高,比刷漆(qi)(qi)(qi)(qi)(qi)提高工(gong)效5-10倍,適(shi)用(yong)于大面(mian)積(ji)的(de)表面(mian)及(ji)人(ren)工(gong)不易涂刷的(de)死角(jiao)(jiao)畸型(xing)表面(mian)。缺(que)點是(shi):需具備噴(pen)(pen)(pen)(pen)漆(qi)(qi)(qi)(qi)(qi)的(de)專用(yong)設(she)備、油漆(qi)(qi)(qi)(qi)(qi)利(li)用(yong)率低、污染嚴重(zhong)。噴(pen)(pen)(pen)(pen)漆(qi)(qi)(qi)(qi)(qi)施工(gong)的(de)質量主要取決(jue)于操作者的(de)技術熟(shu)練程(cheng)度(du),油漆(qi)(qi)(qi)(qi)(qi)粘度(du)、工(gong)作氣壓、噴(pen)(pen)(pen)(pen)槍(qiang)與物(wu)體(ti)的(de)距離。三維網技術論壇6 a6 }: L2 ?6 J
噴漆(qi)時使用(yong)油(you)漆(qi)的粘(z退翅han)度(du)要根據油(you)漆(qi)的種類、工作氣壓(ya)、環境溫度(du)來靈活(huo)掌握。一(yi)般(ban)(ban)應控制在15-35滴/分鐘;工作氣壓(ya)為(wei)(wei)3-6kg/cm2 ;噴槍與物體表面(mian)的距離一(yi)般(ban)(ban)約(yue)250-400mm為(wei)(wei)宜;噴出的漆(qi)流方向應盡量垂直于物體表面(mian)約(yue)在10-12米/分鐘勻速(su)運槍為(wei)(wei)好
