3HVLP環(huán)保省漆噴槍和RP省漆高效噴槍有一個(gè)共同的特點(diǎn),即霧化氣壓較低,涂料的傳遞效率都高于65%以上,在噴嘴結(jié)構(gòu)上也還有一個(gè)共同的特點(diǎn),就是都采用了當(dāng)今先進(jìn)的一項(xiàng)設(shè)計(jì)即空氣擾流板設(shè)計(jì)(圖五),這樣就確保了霧化空氣均勻地從風(fēng)帽內(nèi)部噴射出,當(dāng)霧化空氣均衡后,其霧化的涂料也就非常均勻,從而也就保證了涂料顏色的噴涂均勻。
由于RP省漆高效噴槍的涂料傳遞效率已非常接近HVLP噴槍,以往在美國只能使用HVLP噴槍,但從去年起,RP省漆高效噴槍已獲得美國20多個(gè)地區(qū)的認(rèn)可及批準(zhǔn)使用。
