Epoxy resin mortar is a special mortar composed of epoxy resin, curing agent, plasticizer, thinner, filler, etc. It has excellent corrosion resistance, weather resistance, wear resistance, water resistance, oil resistance, chemical resistance and other characteristics, so it has been widely used in buildings, bridges, tunnels, water conservancy projects and other fields.
The construction of epoxy resin mortar mainly includes the following steps:
1. Preparations.
1.Clean the base layer: clean the surface of the base layer that needs to be constructed to remove impurities such as oil and dust.
2.Ingredients: According to the ratio provided by the manufacturer, the epoxy resin, curing agent, plasticizer, diluent, filler and other raw materials are mixed evenly according to the proportion.
3.Stirring: Add the mixed raw materials to an appropriate amount of water for stirring, stir evenly and leave for a period of time to let the mortar fully mature.
Second, the construction process.
1.Apply the base mortar: Apply a layer of bottom mortar on the surface of the base layer with a thickness of about 2-3mm.
2.Laying fiberglass cloth: Lay a layer of fiberglass cloth on the bottom layer of mortar, and the laying of fiberglass cloth should be smooth and wrinkled.
3.Apply top layer mortar: Apply a layer of layer mortar on a fiberglass cloth with a thickness of about 2-3mm.
4.Curing: After the construction is completed, it needs to be cured for more than 24 hours to ensure that the mortar is fully cured.
3. Precautions.
1.Construction temperature: The construction temperature of epoxy resin mortar is generally required to be above 5, and construction in a low temperature environment is avoided.
2.Construction environment: The construction environment should be kept dry and well ventilated to avoid the humid environment affecting the curing quality of the mortar.
3.Construction tools: Construction tools should be kept clean and dry to avoid impurities such as oil stains affecting the curing quality of the mortar.
4.Curing time: The curing time should be sufficient to ensure that the mortar is fully cured and avoid the quality degradation caused by premature use.
In short, the construction of epoxy resin mortar needs to be carried out in strict accordance with the ratio and construction requirements provided by the manufacturer to ensure the construction quality and service life.
