Foam Glass Blocks Manufacturing

Transcription

1 Foam Glass Blocks Manufacturing Presentation at Horizon 2020 NRW Event March 2018

2 What are foam glass blocks? Foam glass Lightweight, rigid insulating material composed of millions of completely sealed glass cells, each an insulating space. Often referred to also as cellular glass Blocks The superior properties of blocks made of foam glass have made them ideal insulation material for construction industry. Main properties include: Completely noncombustible Has zero smoke development and flame spread classification Ecology-friendly Production process utilizes waste recycled glass as a raw material. Low thermal conductivity Can be used as insulation material in the range of -260 C to +485 С Low noise conductivity Sound absorption figure reaches 56dB Dimensionally stable Has coefficient of thermal expansion similar to concrete and steel Waterproof Since it is made of pure glass Acid resistant Since made of glass Pest-resistant Due to its inorganic nature More than 100 years life-time

3 Peripheral conveyor Production Missing part line R&D Our related uniquely to designed chemical fully features automated of the production glass line necessary is able to manufacture to batch foam glass blocks priced at 40-45% lower Collecting recycled glass Molds cleaning Molds are filled with the batch Foaming process Cutting Crushing recycled glass Transfer to annealing oven Packaging Preparation of batch Annealing P r e p a r a t i o n C o r e p r o d u c t i o n ( L f G - d e s i g n e d ) F i n i s h i n g

R&D organizations Industrial labs Industrial mills producers Lab tests Reactor systems producers Mixing Systems producers Recycling players Knowledge contribution to foaming process research Lab tests performance Development and adoption of equipment to batch technology Pilot equipment Development and adoption of equipment to batch technology Pilot equipment Development and adoption of equipment to batch technology Pilot equipment Analysis and matching of waste glass types

6 Technological expertise reference fully commercial manufacturing facility LfG team has designed, constructed and assembled two fullscale commercial foam glass production lines in the Russian city of Vladimir. The lines were deployed during the period of 2014 and 2015 and are currently fully operational with overall annual manufacturing capacity of up to 110,000 cubic meters
