Epoxy coating epoxy coal tar paint oil tanks anti corrosion paint

Step 1: Surface treatment
As a kind of anti-corrosion coating, the effect of epoxy coal asphalt paint is closely related to the quality of the surface treatment of the base layer. If the base surface is not sufficiently smooth and clean, the coating effect will be greatly reduced.
Therefore, before coating epoxy coal asphalt paint, it is necessary to fully clean and treat the base surface. Cleaning can be done by scraping and rinsing. At the same time, for more serious rust to be treated in other ways, so that the coating effect will be better.

Step 2: Preparation of epoxy coal asphalt paint
When preparing epoxy coal tar paint, it is first necessary to add epoxy resin to acidic coal tar pitch, then add curing agent, stir evenly, and finally add diluent, stir until completely uniform.
In this process, it is necessary to ensure that the material involved in the preparation is clean (no dust, impurities, water, etc.), otherwise it will affect the quality of the paint.

Step 3: Apply lightly
When coating epoxy coal tar paint, it is necessary to achieve specific thin coating operation. This is the key to anti-corrosion effectiveness. If the coating is too thick, the cable specimen disk is easy to form air bubbles, affecting the performance of the coating.
Therefore, when coating epoxy coal tar paint, it is necessary to be divided into several thin layers, and the interval between each thin layer needs to be more than 6 hours. And the amount of coating for each layer should be controlled in accordance with the best use of the material.

Step 4: Process control
The importance of process control can not be ignored when coating epoxy coal tar paint. In each link of preparation, mixed cooking and coating, it is necessary to do a good job of control to ensure the uniform and stable quality of epoxy coal asphalt paint.
The first is the process control in the preparation process, including the amount of resin input, the viscosity of acid coal pitch and so on. Secondly, it is necessary to control the temperature and stirring speed in mixing. Finally, different coating methods such as brush coating, roll coating and spray coating are needed to control the coating process.
In short, in order to obtain good results in the coating of epoxy coal asphalt paint, "it is necessary to combine the above factors to control.

Step 5: Inspection and acceptance
The coating quality of epoxy coal asphalt paint can not only rely on the preparation and coating process control, for the coating film quality, we also need to do some experiments to check.
The test method can be used by scraping film, fluorescence spectrometer and other methods. At the same time, we need to combine the actual situation, the coating effect, hardness, etc., to ensure the performance of epoxy coal asphalt paint.
In short, the epoxy coal asphalt paint needs to be operated according to certain steps and precautions in the process of use, and needs to be careful and patient in the process of preparation, mixing and coating, and needs to carry out some quality inspection and acceptance after coating to ensure the good performance of the coating.
