8.2 Spraying rules
8.2
喷雾要领
Regardless of the type of nozzle, the quality of spraying depends on both the supply pressure and the
product viscosity: as viscosity increases, pressure must also rise, yet the final outcome is also influenced by
the product’s proportions of heavy solvent / light solvent.
无论使用哪种喷嘴,喷涂的质量都取决于喷射压力和产品粘度:压力必须随着粘度上升而增加。然而最终
喷涂效果还与产品与重质溶剂
/
轻质溶剂的比例有关。
A few key points:
几个重点:
• Viscosity: 40 sec CA4: minimum product pressure of 70 bar.
粘度:
40 sec CA4:
产品最低液压
70 bar
。
• Viscosity: 60 sec CA4: minimum product pressure of 90 bar.
粘度:
60 sec CA4:
产品最低液压
90 bar
。
• Viscosity: 90 sec CA4: minimum product pressure of 130 bar.
粘度:
90 sec CA4:
产品最低液压
130 bar
。
The addition of more air serves to reduce the impact width by 25% at a 120-bar pressure; moreover, the
higher the product pressure, the smaller the influence being exerted by the additional air. In order to limit the
production of overspray, it is recommended to never exceed an air pressure of 4 bar.
混入更多空气,可以在
120bar
的压力下降低冲击力达
25%
;此外,产品压力越大,增加进气量带来影响越
小。
为了控制过喷,建议空气压力不要超过
4 bar
。
Using the nozzles with small impact width (XX-09 or 11), whenever the additional air is open, the jet is
practically round.
使用宽度较窄的喷嘴(
XX-09 or 11
)时,无论何时增加进气量,喷射形状基本都是圆形。
