Epoxy resin grouting material-Chuanghong provides technical guidance throughout the construction process

Shijiazhuang Chuanghong New Materials Co., Ltd. Type Epoxy Resin Grouting Material Instructions Our company has been committed to the research, development, production and sales of energy-absorbing insulating grouting materials for large equipment foundations. He has accumulated rich experience and has experience in grouting various foundation forms. At present, the non-shrinkage low-viscosity grouting materials produced by our company are widely used in various fields and have made outstanding contributions to protecting various large-scale equipment of manufacturers. Application fields include: oil (gas) equipment, transmission pipelines, marine engines, reciprocating compressors, nuclear energy equipment, centrifugal compressors, diesel engines, sewage pump generator sets, steam turbines, gas compressors, coal mills, Crusher, storage tank, crane track, etc. With the great development of my country's industry, the introduction of large-scale equipment has always been at the forefront of the world. During the production process, production work cannot be separated from the help of various large-scale equipment. In the past, most of the foundations of equipment in our country were reinforced with cement-based base grouting. As we all know, cement has the advantages of high strength and fast hardening speed. However, cement also has the disadvantage of causing damage to equipment, that is, it has high rigidity and cannot effectively buffer when it is subjected to severe vibrations. Such a large All the force will be borne by our machines, and the consequences are: irreversible damage to the equipment in the long run, damaged parts, and time-consuming and costly repairs. So now we need an equipment foundation that can alleviate this phenomenon, which can absorb and absorb mechanical vibrations and transmit them to the ground. This material is - epoxy resin grouting material. So how does this material mitigate damage caused by equipment vibration? To put it simply, after the epoxy resin grouting material is formed on the equipment foundation, it is equivalent to placing a 10% rubber pad on the equipment foundation. In the same way, people can jump from a height of one meter to the cement floor or jump on a layer of quilts. My feeling is definitely that the latter is easier to accept. Then our grouting material is like that layer of cotton, which plays the role of buffering and energy absorption, protecting the normal operation of our machines for a long time. Grouting construction method: . Preparation before grouting: . The surface of the concrete foundation must be dry, clean, free of oil stains, complete and free of cracks and other defects. Remove stains on the surface of the foundation and use electric picks, chisels and other equipment to remove the cement surface. For laitance, it is better to expose the solid base stones, which can increase the penetration ability of the grouting material and increase the bonding ability of the two materials. 3. The basic parts of the equipment should be polished with sharp corners and the surface should be free of rust and oil stains. . When setting up the formwork, it is necessary to ensure that there are no gaps in the joints of the formwork to ensure the density of the grouting. The distance between the formwork and the equipment base should be no less than 1. . When grouting in winter and other times when the temperature is low, an insulated warm shed should be built to ensure that the viscosity of the material is moderate, thereby ensuring the leveling of the material after grouting and achieving grouting without dead corners. The following is a comparison chart of the performance of epoxy grouting material and cement grouting material: Cured material performance: Testing project standard 3 days per day Final compressive strength - > > > > Flexural strength B/- > > > > Compression elastic modulus B /- / / Linear shrinkage/- / / ＜. ＜.

B (curing agent) for about 10 minutes, pour the mixture (the color is uniform and no floc phenomenon appears) into a low-speed high-power mixer, then add (filler) according to the proportion to mix it with the B mixture, and stir thoroughly for about - minutes to All orthopedics are stained with glue and completely soaked, that is, the mixture is completed. In order to ensure the fluidity of the mixture in winter when the temperature is low, the amount of filler can be appropriately reduced. In addition, be sure to set up an insulated tent when the temperature is low. Ensure the temperature of the material.
