Injection applications - Import export

Cooperation with the designer The characteristics of Bossong anchorages are defined on the base of the specific parameters of each single project, as well as the dimensions of the hole they must be embedded in, that depend on the type of material constituting the substrate. The change of information relating to the knowledge of the building’s state of preservation and of the aims of the provided interventions, drawings and pictures, the pattern of cracks and deformations, as well as the design of interventions, are very important to define the type of anchor that better fits the application and also to evaluate the intervention from the economic point of view. Tests in place The need to give to design engineers the possibility of an assessment of the behaviour of injected anchors in a particular application and in a specific setting has lead Bossong to equip its technician with a mobile instrumentation that allows the execution of onsite tests.

UNIFILO® 800 Series continuous filament mats represent a large choice of tailored reinforcement solutions for efficient manufacture of various composite parts by closed mold process. EFFICIENT PROCESSING U850 high permeability product family enables enhanced resin flow in highly filled systems. U810 product family offers a good compromise between low, medium and high drapability and permeability. CORROSION RESISTANCE Excellent corrosion resistance with Advantex® Glass compared to standard Eglass providing longer service life in applications facing corrosion. U800 products are available with varying strand design and binder contents to match up with specific customer applications. U800 Series mats are compatible with unsaturated polyester, vinyl ester, acrylic and epoxy resins. They are designed to be processed in closed mold processes including RTM (high and lowpressure injection), infusion and compression molding. Applications include heavy truck, automotive and industrial parts.

There are certainly technical and theoretical reasons determining whether an anchorage should be realized with resin or grout. However, in the practical application it is not so easy to define such limit, because of many factors, such as the compatibility with the original materials or simply feasibility problems during the execution. Significant parameters for choosing the type of anchors are type of substrate anchorage length hole diameter setting time and fixing mode waiting times for the loading of the anchorage The thixotropic consistency of the resin, that is useful to prevent from excessive spreading in the interstices of historical buildings, complicates the deep extrusion stage and limits the anchorage length in comparison with the application where the injection is realized with grouts.
