Liquid Primer---How to ensure the quality of the primer coating of polyethylene corrosion-resistant tape

The quality of anticorrosive primer has a vital influence on the anticorrosive effect and life, so the quality of primer must be guaranteed in the construction of the tape.The following is the method to ensure the quality of the primer of polyethylene anticorrosive tape, and the specific operation can be carried out according to the following.

1, when the pipe surface pretreatment, must be within 6 hours of the anticorrosion primer painting construction, and to ensure that the pipe surface is dry, dust-free.

2, be sure to ensure that the consistency of the primer is appropriate, if it is too thick can be added to the matching thinner to dilute, and then paint.

3, in the construction of the primer must ensure that no leakage of paint, no bubbles, condensation and hanging, and the thickness is greater than or equal to 30 microns.

4, in the lower temperature environment or trench construction, should be appropriate to extend the surface drying time, to ensure that the lower part of the pipe surface dryness.

The above is the key to ensure the quality of the primer coating of polyethylene anticorrosive tape, so during the construction of the tape, it must be carried out in strict accordance with the specified operational requirements to ensure the use of the tape and the extension of its life.
