球场施工讲解硅pu水性涂料七大技巧

1、用洁净的水将涂料调至合适喷涂的粘度,以涂-4粘度计测量,合适的粘度一般是20~30秒。如一时没有粘度计,可用目测法:用棒(铁棒或木棒)将涂料搅匀后挑起至20厘米高处停下观察,如漆液在短时间(数秒钟)内不断线,则为太稠;如一离桶上沿即断线则为太稀;要在20厘米高处刚停时,漆液成一直线,瞬间即断流变成往下滴,这个粘度较为合适。
1, use clean water will be adjusted to a proper viscosity of coating spraying, coating -4 viscometer to measure, appropriate viscosity is usually 20~30 seconds. As not available viscometer, visual method: using a stick (the iron rod or stick) will stir the paint to a height of 20 cm to provoke stopped to watch, such as liquid paint in a short period of time (a few seconds) in a continuous line, is too thick; if from the barrel along that break is too thin to just stop at; 20 cm high office, paint liquid in a straight line, instant off flow drip, the viscosity is suitable.
2、空气压力最好控制在0.3-0.4兆帕(3-4公斤力/平方厘米)。压力过小,漆液雾化不良,表面会形成麻点;压力过大易流挂,且漆雾过大,既浪费材料又影响操作者的健康。
2, the best air pressure control in 0.3-0.4 MPa (3-4 kg / cm2). Pressure is too small, poor atomization of liquid paint, the surface will form pitting; excessive pressure easily linked to flow, and the paint mist is too large, the waste of material and the influence of the health of the operator.
3、喷嘴与物面的距离一般以300-400毫米为宜。过近易流挂;过远漆雾不均匀,易出现麻点,且喷嘴距物面远漆雾在途中飞散造成浪费。距离的具体大小,应根据涂料的种类、粘度及气压的大小来适当调整。慢干漆喷涂距离可远一点,快干漆喷涂,距离可近一点;粘度稠时可近一点,粘度稀时可远一点;空气压力大时,距离可远一点,压力小时可近一点;所谓近一点远一点是指10毫米-50毫米之间小范围的调整,若超过此范围,则难以获得理想的漆膜。来源:考试大。
The distance between the 3 nozzle and body surface, general 300-400 millimeter advisable. Easy flow of hanging too close too far; paint mist uneven, prone to pitting, and waste from the nozzle surface far paint mist in the way of flying. The specific size range, should be adjusted according to the viscosity and pressure coating type, size. Slow drying paint spraying distance can be a bit further, fast drying paint spraying distance can be a little closer; near point viscosity thick, can be a little far from the viscosity of dilute; air pressure, distance can be a bit further, pressure hours can be nearly a point; the so-called near a point a little further refers to the 10 mm -50 mm between the small range of adjustment, if more than this range, it is difficult to achieve the ideal film.

4、喷枪可作上下、左右移动,最好以10-12米/分的速度均匀运作,喷嘴要平直于物面喷涂,尽量减少斜向喷涂。当喷到物面两端时,扣喷枪扳机的手要迅速的松一下,使漆雾减少,因为物面的两端,往往要接受两次以上的喷涂,是最容易造成流挂的地方。来源:考试大的美女编辑们。
4, spray gun can be up and down, move around, it is best to 10-12 M / min speed of uniform operation, the nozzle to spray straight on the body surface to minimize oblique spraying. When the jet to surface at both ends, to quickly ease the buckle gun trigger hand, make the paint mist reduction, because the both ends, often have to accept the spraying two times or more, is the most easy to flow caused by the local.

5、喷涂时要下一道压住上一道的1/3或1/4,这样才不会出现漏喷现象。在喷涂快干漆时,需一次按顺序喷完。补喷效果不理想。
5, spraying should be a pinned on a 1/3 or 1/4, so it does not appear leakage and blowout phenomenon. In spray drying paint, need a sequentially after spray. Fill the spray effect is not ideal.
6、在室外空旷的地方喷涂时,要注意风向(大风时不宜作业),操作者要站在顺风方向,防止漆雾被风吹到已喷好的漆膜上造成难看的粒状表面。
6, at the local outdoor open spray, note the direction of the wind (wind not operation), the operator should stand in the downwind direction, to prevent paint mist particulate surface ugly cause wind to spray the paint film has good.
7、喷涂的顺序是:先难后易,先里后外。先高处后低处,先小面积后大面积。这样就不会造成后喷的漆雾飞溅到已喷好的漆膜上,破坏已喷好的漆膜。
7, spraying the order is: first easy, first in the outer. After the first high low, first a small area of large area. So as not to cause sprayed paint spray splashed spray coating has good, destruction has been sprayed paint film.
