Anti-corrosion ground engineering is a special kind of ground engineering, the purpose of which is to prevent ground corrosion and pollution, protect the service life of the ground and environmental safety. The practices, precautions and prevention and control of common quality problems of anti-corrosion ground engineering are as follows:
First, anti-corrosion ground engineering practices.
1.Base treatment: The base treatment of anti-corrosion ground engineering is very important. Substrate treatment includes substrate cleaning, substrate treatment and substrate painting. Grassroots cleaning refers to the removal of oil, dust, loose matter, etc. on the surface of the substrateSubstrate treatment refers to the leveling, grinding, filling and other treatments of the substrate;Base painting refers to the application of primer on the surface of the base layer to enhance the adhesion and anti-corrosion effect of the base layer.
2.Anti-corrosion coating selection: The choice of anti-corrosion coating is very important. It is necessary to choose the appropriate anti-corrosion coating according to the use environment, use requirements, anti-corrosion requirements and other factors of the ground. Commonly used anticorrosive coatings include epoxy floor paint, polyurethane floor paint, acrylic floor paint, etc.
3.Painting process: The painting process of anti-corrosion ground engineering is also very important. The brushing process includes the number of brushes, the thickness of the brushes, the interval between the brushes, etc. The number of brushing times and the thickness of the coating should be brushed in accordance with the requirements of the anticorrosive coating, and the brushing interval should be controlled according to the drying time of the coating.
2. Precautions for anti-corrosion ground engineering.
1.Grassroots treatment should be thorough: grassroots treatment is an important part of anti-corrosion ground engineering, to ensure that the surface of the base is clean, smooth and firm, otherwise it will affect the anti-corrosion effect.
2.The selection of anti-corrosion coating should be appropriate: the selection of anti-corrosion coating should be selected according to the use environment, use requirements, anti-corrosion requirements and other factors of the ground, otherwise the anti-corrosion effect will be affected.
3.The brushing process should be standardized: the brushing process should be brushed in accordance with the requirements of the anticorrosive coating, and the number of brushing, the thickness of the brushing and the interval between the brushing should be controlled, otherwise the anti-corrosion effect will be affected.
4.The environment should be dry: the construction of anti-corrosion ground engineering should be carried out in a dry environment, otherwise it will affect the drying and curing of anti-corrosion coatings, thereby affecting the anti-corrosion effect.
3. Prevention and control of common problems in the quality of anti-corrosion ground engineering.
1.Blistering: Blistering is a common quality problem in anti-corrosion ground engineering, which is mainly caused by incomplete treatment of the base layer and uneven coating of paint. During the construction of anti-corrosion ground engineering, it is necessary to pay attention to the uniformity of base treatment and paint brushing to avoid blistering.
2.Shedding: Shedding is another common quality problem in anti-corrosion ground engineering, which is mainly caused by incomplete treatment of the base layer and uneven coating of paint. During the construction of anti-corrosion ground engineering, it is necessary to pay attention to the uniformity of base treatment and paint brushing to avoid falling off.
3.Cracks: Cracks are another common quality problem in anti-corrosion ground engineering, mainly caused by incomplete treatment of the base layer and uneven coating of paint. During the construction of anti-corrosion ground engineering, it is necessary to pay attention to the uniformity of base treatment and paint brushing to avoid cracks.
4.Missing coating: Missing coating is another common quality problem in anti-corrosion ground engineering, which is mainly caused by uneven coating and insufficient number of brushing. During the construction of anti-corrosion ground engineering, it is necessary to pay attention to the uniformity and number of coating brushing to avoid the phenomenon of missing coating.
The practices, precautions and prevention and control of common quality problems of anti-corrosion ground engineering require construction personnel to carefully grasp and do a good job in every link to ensure that the quality of anti-corrosion ground engineering meets the requirements and provide guarantee for the service life and environmental safety of the ground.
