High-strength non-shrinking epoxy grouting product introduction HGM100 high-strength non-shrinking epoxy grouting material includes A material (resin), B material (hardener), C material (polymer filler) Ingredients, this product does not contain solvents such as solvents that are harmful to humans. Mix at room temperature and use without adding any additional ingredients. HGM100 high-strength non-shrinkable epoxy grout provides a permanent solution for secondary grouting of equipment that requires long-term vibration, shock and chemical corrosion. It has been proven to greatly extend the operating period and component life of moving equipment.
Second, high-strength non-shrinkage epoxy grout product features (1) high strength and early strength: compression, bonding and other physical and mechanical properties are far superior to ordinary cement-based grout.
(2) Self-flow: It can fill all the gaps and meet the requirements of secondary grouting of equipment.
(3) No shrinkage: ensure close contact between the equipment and the foundation to ensure high-precision installation needs.
(4) Water emulsion epoxy cement base: Epoxy resin works together with high quality cement, which is durable and meets environmental protection requirements.
(5) Corrosion resistance: It can withstand long-term corrosion of chemicals such as acid, alkali, salt and grease.
(6) Creep resistance: long-term use under harsh physical conditions without plastic deformation, ensuring long-term accuracy of equipment positioning.
3. High-strength non-shrinkage epoxy grouting products are used for secondary grouting installation of high vibration equipment such as compressors, pumps, punching machines, crushers and ball mills.
Used for grouting in the base area of ​​equipment susceptible to chemical attack.
It is used for orbital foundation, bridge support and other areas under strong pressure.
It is used for reinforcement of anchor bolts and concrete reinforcement of building structures.
Can be used on wet base.
Strong adhesion.

V. Construction Guidelines for High-Strength Non-Shrinkage Epoxy Grouting (I) Surface Pretreatment: The surface of concrete that is exposed to HGM100 high-strength non-shrinkable epoxy grout must be removed from the surface and exposed to a solid base layer to ensure that the grouting surface is clean and dry. No grease. The outer edge of the concrete joint surface is ground with a 25mm thick chamfered edge to increase the grouting area and the base bonding area at the edge; the metal surface to be bonded should also be free of rust (to meet the sspc-sp6 finish requirement).
(2) Formwork: The template shall be solid and firmly lapped. The inside shall be coated with grease, wax or pvc tape to facilitate demoulding; in order to facilitate dumping and installation of the grouting funnel, leave at least 100 mm between the grouting side formwork and the equipment base. Distance, and more than 100mm above the equipment floor. In the inner side of the template, the nail is 25mm thick and 45 degree oblique angled wood line to avoid stress concentration at the edge of the casting body.
(3) Construction temperature: The ambient temperature includes the concrete foundation and air temperature. In order to obtain the best working condition, the ambient temperature during construction and the following 24 hours is preferably controlled at 15 ° C ~ 32 ° C, 20 ° C is most suitable. Summer construction should avoid high temperature at noon, and if necessary, awning should be built; when the temperature is low in winter, the warming shed should be set up in the grouting area to ensure that the construction environment temperature is greater than 15 °C, and the construction should be noon.
(4) Ingredients:
(1) For the extracting agitator (200-250 rpm), firstly mix the A material and the B material separately (the precipitation phenomenon is placed for a long time), and then mix well according to the ratio of the A material: B material = 1:3. Stirring time is about 3 minutes.
(2) Add C material in the low-speed high-power mixer (15-20rpm) to make the A material, B material and C material fully mixed uniformly, the mixing time is about 5-10 minutes; in order to ensure the flow of the mixture when the temperature is low Sex, can reduce C appropriately
Mix the amount of the material or mix it properly with water.
(5) Grouting method (1) Grouting should be poured from one side to the other side; during the grouting process, it can be squeezed but not shaken to avoid trapped air retention; when the grouting distance is greater than 1.5 m, the high grouting funnel method should be used. The grouting is assisted by the principle of gravity differential pressure.
(2) Grouting must be completed as quickly as possible.
(3) The thickness of single grouting layer is controlled between 25mm and 350mm; the grouting depth of single bolt hole is less than 1500mm; when the grouting volume exceeds 1.8m*1.8m*150mm, it is necessary to use the smear plate to stick the expansion joint on the base surface. After the filling is finished, the surface portion of the grout is removed, and the expansion joint is made of a sealing material.
Sixth, high-strength non-shrinkable epoxy grouting packaging specification A material: iron drum 15kg / barrel B material: plastic drum 45kg / barrel C material: paper-plastic composite bag 40kg / bag use weight ratio: (A + B): C = 1:6
Each group has a net weight of 420kg and a groutable volume of about 0.21 cubic meters.
VII. Storage and transportation of high-strength non-shrinking epoxy grout (1) This product A material B is water-based epoxy emulsion and hardener emulsion, which should be stored in a cool place above 5 °C.
Shelf life is 6 months. The material C is a polymer polymer dry-mixed mortar, which should be stored in a dry and moisture-proof environment. The shelf life is 6 months in the unopened state.
(2) HGM100 is non-combustible, non-explosive, non-polluting and radiologically hazardous, and can be stored and transported as general cargo.
