如何防止噴塗噴嘴堵塞?


0

似乎隨機發生。有時,我可以在同一噴頭上的十二個不同場合使用一罐噴漆,但它從不堵塞。有時,它們在首次使用後會堵塞。有時,當我使用它們時,它們甚至會突然堵塞!然後,在不損壞噴嘴的情況下似乎無法疏通。是什麼原因導致噴嘴突然堵塞?如何防止或修復噴嘴?

DISCLAIMER: I've never actually used spray paint.

The clogging is caused by dry paint mainly. To prevent this the paint manufacturers advice, after you've finished using it on the occasion, to turn it upsidedown and spray away the paint that was left in the tube-ways, so that there will be no paint left to dry and cause clogging.

Another reason for clogging is poor quality paint (most likely the reason it cloggs all of a sudden in miduse). I don't think there is anything you can do about it (exept for buying a different brand of paint).

As a last resort you could try soaking the clogged nozzle in paint solvent for a while, but I don't know if that would make any difference.
