In the daily life, glass fabric is used in the areas including computers, walls of houses and medical devices. Besides, glass fabric mesh is one the top raw materials owing to its feature of endurance in the industry of semi-conductive materials and in construction and aviation sectors. Glass fabric, globally used in most products, is one of the products that has been preferred most in the last two decades thanks to the features such as high tensile strength, isolation and heat resistance. Firms also need to develop special machine line for this area which is expected 61,000 million dollar return globally in 2013 according to the data of IPC and NTI.
Brückner’s studies draw attention in ths area that has dense proccessing proceeds. Dirk Stadter, Sales Manager of Brückner Glass Fabric Lines, has made assessments and underlined the possibility of savings owing to the measures in this way of production which has an extensive energy consumption. Stadter stating that glass fabric products go through a series of process has continued as “Melting phase is the first process and it requires 1550°C. After this step, yarns are streched with a special production process and undergo chemical potential both in the process of twisting and following stages. Thus, producers need to apply black wash process to maintain the quality in yarn production. “
Stadter has pointed out that the weight of the raw fabric rises approximately 3% in black fabric applications and he has stated this system is applied in practice in dryers based on IR gas radiators and in circulating convection dryers up to 450°C air heat. As black wash in polluted air is a significant issue, he has said it is a must to clear this polluted air and “ Brückner designed caramelizing line at a level of 120 m/min of fabric speed for the production of printed circuit boards and the process of desizing glass woven fabric” he has stated.
The Duration Of Cooling Process Need To Be Shorten
Stadter has noted that the raw material exposed to high degree of heat during the process of finishing of glass fabric needs to enter into a fast cooling process in the name of making savings. “During the process of desizing in furnace, the effect of the proceed of black wash having an impact on the weight of raw fabric is eliminated from glass fabric. The process, including heating, heat retention and cooling, comprehends nearly 72 hours of time. This duration can be reduced to a time of 44-48 hours by means of furnaces with high technology. This time saving can be provided by dense air control circulation which is also a standard of Brückner furnaces. The most important point here, a very effective isolation and machine have an effective preserved structure” he stated.
Stadter has said when the elapsed time between the processes of heating and cooling decrease from 72 hours to 44 hours, it provides additional saving of 800 kWh approximately. He has emphasized glass fabric becomes sensitive to all sort of mechanical stres with the elimination of black wash. “ Glass fabric for the production of printed circuit board is supported by watery silane and additives such as resin coat. In this direction, this process period not only improves the mechanical stress resistance but also removes the fiber and thread breakage with special measures. At the same time, layer with synthetic resin increases the surface quality of raw fabric” has stated Stadter.
Brückner Machines Provides Savings with Heat System
Stadter expressing that technologies made by Brückner meet the expectations at that point, has explained that high level of heat, needs to be used under the part of convection dryer machine via a special nozzle zone by heating the clean air previously. Stadter has remarked that the saving effect is around 170 kW or 18% of the total heat requirement of a cooling process and added if the convective dryer is only taken into consideration, there is a lower heat demand as a natural consequence. He has explained Brückner offers with design of infra-red radiation gas dryer and integrated usage of exhaust air heat put an end to his words as “gas demand decrases 17% with only these practises. Besides that, it is provided 8% increase in producing capacity. It also provides 25% savings from main energy by using reformist, fruitful and high technology when the chain of glass fabric coat is considered as furnace and silane application for printed circuit industry.”
Brückner Innovations in Technical Textile
Brückner having notable market share with finishing lines of technical textile comes to the forefront in its area with Power-Frame Eco Stenter that provides energy saving up to 30%. Brückner, a small technical office in 1949 and growing globally and fast in the area of textile machine engineering, maintains its feature of being a family-owned business under the management of the second generation in Leonberg, Germany. The firm bringing in many breakthrough in the sector owns several patents. For finishing processes, Brückner produces lines of drying, fixation, sanforizing, continuous dyeing, coat and compression. The firm has made differences with finishing solutions it has developed for especially technical textile and it has brought in several innovations with Power-Frame Eco Stenter.
Brückner, keeps preparing energy efficiency and strong dryer generation to support textile businnessmen in fierce competition and high cost in sector. Brückner stating that the efficiency issue has turned into a notion used frequently among machine producers underlines that it is applied literally by them. The brand has improved a completely new drying technology for woven and knitted fabric finishing. The center of this new dryer is defined as a special heat system working with intelligent control system and integrated heat recovery system.
