An airless pump for variable ratio injections of two-component resins is a device used in the processing of two-component resins. They allow precise control over the quantity and ratio of components, guaranteeing high quality and long-lasting results.
Variable ratio two-component resins are composite materials consisting of two separate components that must be mixed in a specific ratio before use. These resins are widely used in various industrial, construction, repair and other applications where a precise mix is required to achieve the desired performance.
1 – Component A: This is one of the two main components of two-component resins. Generally, component A contains the main polymer or basic binding agent.
2 – Component B: The second crucial component. Component B may contain curing agents, catalysts or other additives necessary to initiate the chemical reaction between the two components and harden the resin.
3 – Variable Ratio: the strength of these resins is that the ratio of component A to component B can vary depending on the application and product specification. For example, some resins require a 1:1 ratio (equal amounts of A and B), while others may need a 2:1 or 4:1 ratio. This variation allows customisation of the resin properties, such as curing time, viscosity and strength.
4 – Storage: The two-component resins are stored in separate tanks, one dedicated to component A and one to component B. These tanks are equipped with pumps to suck the materials in a precise and controlled manner.
5 – Mixing: Before the resins reach the gun or injector, the two components are dosed in a variable ratio according to process specifications. This step can be adjusted according to the needs of the application.
6 – Airless pressure: Once dosed in the correct ratios, components A and B are pushed through two independent airless pumps. The airless pump uses extremely high pressure to push resins through a gun or nozzle.
7 – Application: The mixed resins are dispensed onto the surface or injected into the desired area. The high pressure guarantees an even and controlled distribution of the resins on the surface, ensuring precise application. These resins are used for bonding, structural reinforcement, sealing, protective coating, repairs and other applications.
8 – Hardening: After application, the two components react chemically with each other, causing the resin to harden. The time required for this process may vary depending on the type of resin used and the environmental conditions.
Variable ratio two-component resins are renowned for their versatility and ability to customise their properties. They can be designed to offer a wide range of performance, including mechanical strength, adhesion, chemical resistance and thermal resistance.
QuThese airless pumps for injecting two-component resins at variable ratios are widely used in specialised applications such as concrete structure repair, concrete reinforcement, corrosion protection, composite lamination, aerospace, construction, shipbuilding, automotive, sports equipment manufacturing and much more. They are the hidden engine of many industries, guaranteeing high quality work and lasting results.
