1. In the treatment of the substrate, the substrate is required to be polished flat and smooth, without obvious burr protrusions or concave and convex surfaces, and without angular welds.
2. Pay attention to the weather conditions during construction and avoid rain, snow or windy weather. Too high humidity in the air will greatly affect the drying speed of the paint film, resulting in problems such as the paint film not drying.
3. In order to get a better waterproof effect, a layer of glass cloth can be added after the primer construction. The thickness of the glass cloth is preferably or.
4. For the anti-corrosion of buried pipelines, a thick-coated epoxy coal asphalt primer is used, and then a thick-coated epoxy coal asphalt topcoat is used.

General usage of asphalt paint:
1. During the storage period, the allowable viscosity is large. Before use, it must be fully stirred to avoid excess diluent, so as to prevent the lack of paint film and reduce adhesion and anti-rust performance.
2. If there is serious rust on the metal surface of the construction, it needs to be painted after rust removal.
3. The oil stain on the galvanized iron parts must be wiped clean with solvents before it can be brushed, otherwise the paint will lose its adhesion function, and there will be falling off or cracking.
Asphalt paint is composed of coal tar asphalt and coal tar as the main raw materials, adding thinners, modifiers, driers and other organic solvents. The ratio of the main raw materials is generally different due to different climate, temperature and use environment, and the use of modifiers is added according to different needs.

OK. This technology is only available to Huatong's materials. Huatong color or colorless pavement special spraying agent, and can make the original pavement increase the service life.
Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving pellets to resist road damage to the road surface caused by driving and natural factors, making the road surface smooth and dusty, impermeable and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction.
The asphalt structure layer of asphalt pavement itself belongs to the category of flexible pavement, but its base layer can also use rigid cement concrete or semi-rigid hydraulic material in addition to flexible materials.

Asphalt paint with rosin perfume can be used as a thinner. Asphalt paint is composed of coal tar asphalt and coal tar as the main raw materials, and organic solvents such as thinners, modifiers and driers are added. The ratio of the main raw materials is usually different due to different climate, temperature and use environment, and the use of modifiers is added according to different needs.
Asphalt paint is mostly used in underground pipeline anti-corrosion projects.

Dear, I am glad to answer for you: what is the use of asphalt paint? A: Good afternoon, dear kiss! <>
1. The construction sequence should be made as a node first, an additional layer, and then a large area of painting; 2. Plate seam sealing: the seam groove is cleaned and filled with sealing material; 3. Seam surface reinforcement: After the seam is sealed, an additional layer of empty paving should be made; 4. Overall coating:
Start with a primer. Dilute with water and coat the roof all over. After drying, apply it in layers.
The coating is sandwiched and spread with mesh cloth and other carcass, which should be paved while coating; The carcass should be scraped flat to remove air bubbles and saturate the coating; The coating of the uppermost coating of the carcass should not be less than twice, and its thickness should not be less than 1mm; When the two-layer carcass is adopted, the upper and lower layers shall not be laid perpendicular to each other, and the lap joints shall be staggered, and their spacing shall not be less than the width of 1 3; 5. Make a protective layer: After the last surface is dried, you can spray water-based reflective heat insulation coating. It can also be used to sieve the fine sand or colored sand of the powder, and remove the mother or vermiculite and other spreading materials; When using mortar and blocks as a protective layer, an isolation layer should be laid on the waterproof layer, and then the surface of the mortar should be smoothed and calendered, and the surface lattice joint area is 1m2, and a 30mm gap is reserved between the parapet wall and coated and embedded.
