Description
Technical field:
The present invention relates to the processing fields of metal welded tube, and in particular to a kind of cleaning by degreasing for metallic conduit
Agent.
Background technique:
Metal surface spray painting is a kind of method for protecting the not oxidized corrosion of metal.The corrosion phenomenon around us occurs
Refer to that various types of materials (comprehensive function for having chemistry, electrochemistry and several physical factors) under environmental activity is damaged, performance
Decline or the deterioration of state.It and is then a kind of critically important anticorrosive metal holding means in metal surface spray painting coating.Well
Spray painting coating protection layer keep it is continuous whole lossless, be well combined, can become inhibit corrosive medium intrusion barrier.
Since corrosion is irreversible spontaneous process, even good spray painting coating retaining layer, it is also difficult to protection gold
Category do not corrode, especially when metal surface spray painting coating layer combine it is bad, be damaged, or have pin hole, be bubbled, cracking,
The defects of falling off, varnished protective effect will be greatly reduced, or even the disastrous effect for causing metal erosion to aggravate.So to spray painting
Coating metal corrosion factor carries out serious analysis, and it is very necessary for taking effective countermeasure prevention.
The clean-up performance of metal surface seriously affects the binding force of coating layer of paint, the water of article surface residual or absorption,
The elimination such as greasy dirt and other foreign matters is not clean, often generates pin hole, dross, peeling or combines the failures such as bad.
