The Master's final project investigated properties of paperboard coated with additional coatings. Usually paperboard is used for the paperboard packaging production. The paperboard surfaces can be coated with various additional coatings, one of them – dispersion coating. For dispersion coating can be used stainless coating rods with stainless steel wire. In this research work it was made absorption tests, using Cobb120 methodology and dynamic surface wetting angle tests. It is also made coated and uncoated paperboard surface static and dynamic friction coefficient tests. Cobb120 research allows estimate fluid (water) absorption to the coated and uncoated paperboard surface over a relatively long test period (120 sec), meantime, the dynamic wetting angle test allows monitoring of liquid absorption in the selected time interval, which in this research was between 0 to 6 s. The surface friction study shows – the static and dynamic coefficients of friction for coated and uncoated surfaces. Excluding the previously described scientific research - the work consists of 5 chapters: technical – economic characteristics, technology, industrial safety and the environment, financial and economic calculations. In technology projection section was designed paperboard packaging with offset technology. There were made technology calculations of ten different types of packages, from which the two types of packaging were covered with anti-slip dispersion coating, all equipment has been selected for these technologies. According to the calculations, it was made up the premises and equipment layouts. It provides the necessary quality control conditions and factors which must be carried out to ensure proper product quality. In safety and ecology section carried out a professional risk assessment, which should include a means which guarantee the safety of employees at work. In the final chapter – the financial and economic calculations, based on technology designed – are calculated the products costs, the payback time and investments efficiency. |
