噴(pen)(pen)(pen)砂(sha)槍(qiang)(qiang)：一(yi)般(ban)噴(pen)(pen)(pen)砂(sha)槍(qiang)(qiang)都(dou)是(shi)用(yong)雙進(jin)風鎢鋼噴(pen)(pen)(pen)槍(qiang)(qiang),現在(zai)有了(le)碳(tan)化硼雙進(jin)風噴(pen)(pen)(pen)槍(qiang)(qiang)使(shi)用(yong)壽命更長,但不能撞碰,容(rong)易碎，因為硬(ying)度高，耐(nai)磨性好,目前大部分(fen)(fen)還是(shi)使(shi)用(yong)雙進(jin)風鎢鋼噴(pen)(pen)(pen)槍(qiang)(qiang).噴(pen)(pen)(pen)嘴分(fen)(fen)M6,M8,M10,M12等幾種,每(mei)個品種的(de)耗氣(qi)量不同(tong),如M6噴(pen)(pen)(pen)嘴基本(ben)上2方(fang)多一(yi)點氣(qi)就(jiu)夠了(le),而(er)M8噴(pen)(pen)(pen)嘴需4方(fang)每(mei)分(fen)(fen)鐘(zhong)的(de)氣(qi),而(er)4方(fang)每(mei)分(fen)(fen)鐘(zhong)的(de)空(kong)(kong)壓(ya)機螺桿(gan)式要(yao)4萬元(yuan)左(zuo)右,活(huo)塞式要(yao)1.6萬左(zuo)右.價(jia)格比噴(pen)(pen)(pen)砂(sha)機高很多,在(zai)購(gou)買時一(yi)定(ding)注意(yi),有好多用(yong)戶(hu)買了(le)開放(fang)式噴(pen)(pen)(pen)砂(sha)機因為空(kong)(kong)壓(ya)機帶不起來,而(er)無法(fa)使(shi)用(yong),又(you)要(yao)重新購(gou)空(kong)(kong)壓(ya)機.增加(jia)了(le)麻煩和負擔(dan).另(ling)外(wai)注意(yi),市場上說是(shi)4方(fang)每(mei)分(fen)(fen)鐘(zhong)的(de)空(kong)(kong)壓(ya)機價(jia)格差別很大,
