HRVP/HRVP Extended HRVP Block Reinforcing System for Defective Marble Blocks by Vacuum Device

This treatment creates a strong reinforcement around the cut slab (the thickness of reinforcing varies according to request conditions and the available quantity of resin). Treatment phases: Block washing: by means of a high pressure hydraulic nozzle utilized by an operator Dry of blocks: by means of drying chamber heated by means of gas or electric hot air generators Preparation of block to be hardened: to be realized in the apposite area. It is a completely manual operation developed by means material provided in the supply (bridge crane excluded) Vacuum operation and resin injection: to be realized inside the machine. The block to be repair is covered into a special device and after resin is injected into the block after the creation of vacuum Catalysis of reinforced block patented HRVP EXTENDED BLOCK CORE REINFORCING BY MEANS OF VACUUM DEVICE AND PRESSURE By using Hrvp Extended is guaranteed the resin percolation into all fractures connected to the external block surface. This operation gives the best solution to get a block that can be cut even if the material was fragile or really fractured. There are now two treatments with a new phase: Block washing: by means of a high pressure hydraulic nozzle utilized by an operator Dry of blocks: by means of drying chamber heated by means of gas or electric hot air generators Preparation of block to be hardened: to be realized in the apposite area. It is a completely manual operation developed by means of material provided in the supply (bridge crane excluded) Vacuum and resin-resin injection: to be realized inside the machine. The block to be repair is covered into a special device and after resin is injected into the block after the creation of vacuum Pressurization on the hardened block (with the Hrvp Extended system only): to do inside the surge tank of the plant line just after the injection of resin. The special pressuring cycle makes resin deep penetrating inside all fractures of the block, completely reinforcing and improving it Catalysis of reinforced block: once the blocks have been reinforced and hardened they are placed inside hardening chambers that previously have been heated by means of electric or gas generator until the resin becomes hard CHARACTERISTICS RESINS We use bi-component epoxy resins studied properly for the HRVP process. The special formulations produced change according to the material of the block to be worked and to its fractures. The plant sale contract includes the resins supply for a period to be established during the negotiations. COMPLEMENTARY TOOLS Besides studying the usage, Prometec has optimized shape, dimension and quality of all complementary tools necessary for the working cycle good execution. The plant sale includes them in the supply. CONSUMABLE MATERIALS The first supply includes all the expendable materials, such as: Materials for resin confinment Aerating material Reinforcing layers Draining material Fittings for the different connections Various pipes PLANT ASSEMBLY, START- UP AND COMMISSIONING Besides the plant assembly and start up, Prometec proposes its staff for a period of training to guarantee the nal result on all processed and processable materials by the purchasing company.
