Epoxy grouting material
Product characteristics
High strength and early strength with excellent Due to the mechanical properties such as compression resistance and bonding of cement-based materials, it has higher early strength.
The non-shrinkage ensures that the grouting layer is in complete contact with the bearing surface after final formation, ensuring high accuracy in equipment installation.
Creep resistance: It can be used for a long time without plastic deformation under harsh physical working conditions such as freezing and thawing alternating between ℃ and +℃, vibration and pressure.
High toughness can resolve dynamic loads transmitted by moving equipment that may cause the cement-based grouting layer to burst.
Corrosion resistance can withstand long-term contact corrosion with chemicals such as acids, alkalis, salts, and greases.
Product physical properties
(Standard curing conditions: ℃, no maintenance required during construction, which is a major advantage over cement grouting materials)
Specific gravity (density) Conventional value /, depending on the formula, and There is a positive correlation between filler and aggregate content.
The conventional product appearance is a tan solid after curing and molding. Other colors can also be customized, and the exposed surface has a smooth and bright effect.
The pot life (℃) ~ hours is positively correlated with the amount of mixing and pouring at one time.
The exothermic peak ranges from ℃ to ℃, which is generally negatively correlated with the filler and aggregate content.
Compressive creep (°C) under pressure, within half a year/.
The thermal expansion coefficient (°C~°C) after complete solidification and molding (greater than days) is between ~°C.
Safety
It adopts a non-toxic and non-volatile formula, which is friendly to the environment and human body. However, it may be slightly irritating to some people's skin. Long-term contact with the skin should be avoided. Necessary protection should be worn and maintained during use. The environment should be ventilated. Wash immediately after contact with the skin. If it splashes into the eyes, rinse immediately with plenty of water. If swallowed by mistake, drink water immediately to induce vomiting and seek medical treatment.
Packaging and Storage
Conventional liquid components are packed in iron barrels or plastic barrels, and solid components are packed in plastic bags or paper-plastic composite bags, which can also be customized according to needs.
The storage conditions of general chemicals should be met in a cool, dry, airtight and ventilated environment. Due to the stable chemical properties, the product can be stored for at least one year under normal conditions. It can still be used after it has been inspected and inspected.
Among them, the main performance requirement of epoxy resin grouting material is compressive strength. If it cannot meet the performance requirements in terms of strength, it cannot be used.
According to the strict design plan, choosing materials with excellent performance is your right choice.

Surface pretreatment
The concrete surface that comes into contact with epoxy resin grouting material must be chiseled. Remove the floating grout on the surface and expose the solid base layer, ensuring that the grouting surface is clean, dry and free of grease. The outer edge of the concrete joint surface is ground into thick chamfers to increase the bonding area between the grouting material and the foundation at the edge. The metal surface to be bonded should also be free of rust (meet the smoothness requirements of ,).
Construction temperature
The ambient temperature includes the concrete foundation and air temperature. In order to obtain the best working condition, the material must be placed in the environment for several hours before grouting. The ambient temperature during construction and subsequent hours is most suitable. . Avoid high temperatures at noon during summer construction. If necessary, build an awning. When the temperature is low in winter, a warm shed should be built in the grouting area to heat up to ensure that the construction environment temperature is higher than the normal temperature. Construction should be done at noon.
Mixing
Use a hand-held mixer to thoroughly mix (resin) and (hardener) for about 10 minutes. Add (filler) to a low-speed high-power mixer to mix with the mixture. Stir thoroughly until the orthopedics are completely infiltrated. It will be completed and it will take about minutes. In order to ensure the fluidity of the mixture when the temperature is low, the amount of filler can be appropriately reduced.
Epoxy grouting
The grouting material should be poured from one side to the other. During the grouting process, it can be squeezed but not shaken to avoid trapped air. If the grouting distance is greater than 100 meters, a high-level grouting funnel method should be used. The principle of gravity pressure difference assists grouting. The grouting work must be completed continuously and as quickly as possible. The thickness of a single grouting layer is controlled to within . When the grouting depth of a single bolt hole is less than the grouting volume, a foam board must be used to stick an expansion joint reserve strip on the foundation surface. After the grouting is finally set, the surface part is cut out, and then epoxy is used. The sealing limbs are closed to create permanent expansion joints.
Check the density
After the grouting is completed, use a hammer to tap the equipment substrate. If a dinging sound is heard, it indicates that the grouting layer is dense. If a thumping sound is made, it indicates that the grouting layer is hollow.
Surface finishing and form removal
After grouting and before the epoxy grouting material is initially set, in order to achieve a beautiful effect, the exposed surface can be polished with a putty knife and the form can be removed after final setting. The above data is for reference only, please be sure to test the relevant performance before use.
Grouting method
Edit
, Self-weight method
The self-weight method uses the good fluidity of the material during grouting construction to flow freely within the grouting range to meet the grouting requirements. method.
, High-level funnel method
The high-level funnel method is a method of increasing the potential energy difference of grouting to meet the grouting requirements when the fluidity of the grouting material alone cannot meet the requirements during grouting material construction.
, Pressure grouting method
Pressure grouting method is a method that uses grouting pressurizing equipment to meet grouting requirements during the construction of grouting materials.
The distinction between epoxy resin grouting materials
Epoxy resin grouting materials cannot use water as a curing agent. If the epoxy resin grouting material can add water, it is fake. This is a hype concept. According to [] long-term construction site guidance experience, it is found that if epoxy resin is mixed with moisture, its performance will be seriously reduced, and the contact surface with epoxy resin during construction must be dry to achieve optimal performance)
According to different construction conditions, Epoxy resin grouting products with different properties are developed to be suitable for construction in various harsh environments.
