FASLOC – resin cartridges

The data selected for LCA analysis comes from ITB-LCI questionnaires completed by DSI Underground Chemicals sp. z o.o. using the inventory data, ITB and Ecoinvent v. 3.9.1 databases and KOBiZE. KOBiZE data is supplemented with Ecoinvent v. 3.9.1 data on the national electricity mix impact where no specific indicator data is provided. No specific data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency are judged as good. The allocation rules used for this EPD are based on general ITB PCR A. Production of Fasloc resin cartridges is a line process conducted in the factory of DSI Underground Chemicals sp. z o.o., located in Mikolów (Poland). Allocation was done on product mass basis. All impacts from raw materials extraction and processing are allocated in module A1 of the LCA. Impacts from the global line production DSI Underground Chemicals sp. z o.o. were inventoried and 100 % were allocated to the production of Fasloc resin cartridges based on the annual production volume expressed in kg. Water and energy consumption, associated emissions and generated wastes are allocated to module A3. Packaging materials were taken into consideration. According to the standard EN 15804+A2, products used for the production of other products should be declared at the production stage. Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included in the calculations. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804+A2, machines and facilities (capital goods) required for the production as well as transportation of employees were not included in LCA. The production of etiquettes/printing was not considered.

FASLOC resin cartridges are used in mining workings (roofs, sidewalls, floors) for the main bolting support, for fixing rods and bolts as well as auxiliary bolting. They are also used for bolting and anchoring steel elements in tunnel construction and all types of civil engineering structures. Resin anchor bolting provides effective long term strata support in underground softrock, hardrock, mining and tunnelling. The resin anchored bolts can be fully encapsulated for corrosion resistance and point anchored and tensioned to plate and mesh for confinement of the coal or rock face. DSI FASLOC resin anchors are manufactured from a sophisticated blend of reinforced polyester resins and inert fillers. In addition to the typical two-part mastic/catalyst arrangement, DSI manufacture two speed anchors containing two distinct resin gel times in the same package where separate point anchor and tension times are required for bolting. DSI also provides a two capsule arrangement where 2 resin capsules are joined and folded in half for packaging, and are available in either single-speed or two-speed configurations. FASLOC resin capsules comprise an outer clear plastic heat sealed sheath clipped at both ends. Within this are two separate internal compartments consisting of: 1. Colour coded reinforced thixotropic polyester resin mastic of a specific setting speed and 2. Catalyst/hardener to activate the resin. In addition to the typical two-part mastic/catalyst arrangement, Duo Speed cartridges contain two distinct resin gel times – Fast and Slow – in the same convenient package. On rotation of the bolt through the capsule in the bolt hole, the two capsule compartments are ruptured and the components are mixed together initiating a rapid polymerization process and cure to form a rock solid anchor.
