Epoxy resinepoxy resinanchoring agents is a material specifically used for fixing and reinforcing materials such as concrete, bricks, stones, wood, or steel. According to their different components and uses, they can be divided into three types: chemical epoxy resinanchoring agents, mechanical epoxy resinanchoring agents, and pressure epoxy resinanchoring agents.
Chemical epoxy resinanchoring agents are materials that firmly fix the substrate and core materials through chemical reactions; Mechanical epoxy resinanchoring agents fix the core material and substrate through mechanical structure or principles, forming a stable mechanical structure; Pressure epoxy resinanchoring agents are materials that are fixed using the principle of pressure.
In construction projects, epoxy resinanchoring agents are commonly used to repair defects on the surface of concrete walls or columns, install stairs, handrails, and fix roof components. In mechanical equipment manufacturing, it is used to repair machine parts and fix various mechanical components.
There are various types of epoxy resinanchoring agents, which can be divided into the following main types based on their main components and usage methods:
Chemical anchoring agent:
Chemical anchoring agent is a type of anchoring agent that achieves fixation effect through chemical reactions. The principle is to inject chemical anchoring agent into the anchoring hole, allowing it to react inside the hole, forming a strong colloidal solidification layer, thereby achieving a firm anchoring between steel bars and concrete substrates. It is usually suitable for anchoring scenarios with heavy loads such as shear and tensile to ensure the safety and stability of the entire structure.
Injectable anchoring agent is a type of chemical anchoring agent, characterized by mixing the hardening agent and resin in a certain proportion, and then injecting the mixed anchoring agent into the borehole through a dedicated syringe. This anchoring agent has strong corrosion resistance and is suitable for fixation in acidic and alkaline environments.
Capsule type anchoring agent is to separately pack the hardener and resin into two capsules. During construction, the hardener capsule is first inserted into the hole, and then special auxiliary tools are used to press into the resin capsule and mix. It has high requirements for construction elevation and is suitable for high difficulty construction.
Mechanical anchoring agent:
Mechanical epoxy resinanchoring agents, also known as force anchors, are commonly used in construction projects for anchoring steel bars and supporting deep foundation pits. It controls the load by pre embedding anchors, which have the characteristics of simple installation, low cost, and long service life. However, it is only suitable for medium to low load situations.
Other types of epoxy resinanchoring agents:
In addition to chemical and mechanical epoxy resinanchoring agents, there are also mortar type epoxy resinanchoring agents, which are made by mixing specific proportions of cement, mortar, inorganic and organic materials.
Hydraulic anchoring agent is a new type of anchoring technology that combines anchors, hydraulic systems, and control systems to form a precise and controllable anchoring technology.
Adhesive anchoring agent is another common anchoring method, and its principle is similar to chemical anchoring agent, but the specific composition and usage may vary.
In practical engineering, the choice of anchoring agent mainly depends on factors such as the specific needs of the project, construction environment, load conditions, and cost considerations. Therefore, when selecting and using epoxy resinanchoring agents, it is recommended to consult professional engineers or consult relevant technical information to ensure their safety, effectiveness, and economy.
