Pipeline anticorrosive coating how to choose? Here for you to share the knowledge of pipeline anticorrosive coating -- epoxy coal tar paint [anticorrosive characteristics]

I. Product Overview:

This is on the basis of special modified resin, adding special additives, fast drying additives, corrosion resistant pigments, etc., by improving the previous process prepared by the two-component buried pipeline, pipeline and other special heavy anti-corrosion coating.

4, diluent and dilution ratio: Crown brand matching special diluent, brush the reference dosage of 3-10%.

3. If the ambient temperature is lower than 10℃, the natural curing time must be appropriately extended.

2, open the bucket mixing, thoroughly stir the coating to the bottom of the bucket without sediment, according to the coating and curing agent delimit proportion (weight ratio) to add special curing agent; Stir well and cook for an average of 10-15 minutes before use. Construction cost saving, one-time film formation, room temperature curing film formation. For new steel, surface cleanliness can be directly coated to Sa1 or St2 level. The prepared lacquer is recommended to be used up in about 2 hours (20℃). Do not pour the prepared lacquer into the original lacquer. It can be used for anticorrosion of industrial sewage, seawater, fresh water buried pipeline wall, liquid storage tank wall, concrete, sluice, Marine wharf, pan engineering, Marine measures and other equipment.

Two, the scope of use:

The coating has strong adhesion, water resistance, acid and alkali resistance, wetting resistance and other functions.

3, easy construction, room temperature curing.

2, special modified resin film formed after the formation of interpenetrating network polymer anticorrosive coating, effectively prevent the change of the coating, improve the adhesion resistance, wear resistance, corrosion resistance and wetting resistance of the coating.

Three, the main features:

1, with low water absorption, sea water resistance, microbial corrosion resistance, good seepage resistance, good water resistance, strong electrical insulation and other convex starting point.

Iv. Product technical requirements:

Item Specifications Measurement Scale Appearance Black or other color viscosity (coated -4 cups), S, 25℃, ≥ 45 GB/T1723 -- 1993 drying time (25±1℃, h)≤ table dry 4 GB/T1728 -- 1989 Solid work 72 Service temperature, The construction method of high pressure airless spraying, gas spraying, brush coating adhesion (gradation method, grade), ≤ 1 GB/T9286 -- 1998 room temperature water resistance for 1 year composite coating no change GB/T1733 -- 1993 FIVE, construction parameters:

1, construction in the dust-free, grease-free, dry surface. It has the advantages of low water absorption, sea water resistance, microbial corrosion resistance, good seepage resistance, excellent water resistance, strong electrical insulation and so on. The construction temperature is above 5℃. For other construction surfaces, it is required to be clean and dry, free of grease, dust and other pollutants, remove loose rust layer, oxide scale and old paint film, and make the surface cleanliness reach St2 level.

5. The period of validity is half a year. After the period of validity is exceeded, it can still be used after being repaired and qualified.
