BMR’s attention to the production process is aimed at the ceramics industry achieving high quality and highly competitive products both from a technological and aesthetic point of view. To this end, the finishing segment of which BMR is an international leader includes an important surface treatment phase that gives added value to lapped and polished surfaces.
In general, the first treatment is that of acid pickling, carried out to preserve any shadings deriving from subsequent washing with aggressive detergents. With pickling, the surface is treated with an acid solution applied through a sponge roller and is then simply rinsed with water.
Subsequent treatments are distinguished according to the different surface types, which can be classified into two macro categories:
– polished technical porcelain, full body or double loader;
– lapped/glazed technical porcelain.
Thanks to the collaboration with companies specialized in tools, glazes and raw materials for treatment, BMR has developed three lines of treatment machines, with the main purpose of improving cleanability and shine: TopCoat, TopFinishing, SuperShine.
TopCoat applies products that include acid pickling and fillers to preserve the product’s original gloss from the lapping process.
TopFinishing is a 6-head machine that allows the dry application of filler fluid. Thanks to the balance of weight, speed and type of product applied, TopFinishing allows the increase of Gloss during the process.
SuperShine is a mechanical heat treatment able to increase the degree of gloss coming from the lapping of 30 points and more.
The mechanical heat process takes place in consideration of:
– advancement speed of the machine belt;
– tilting speed of the upper bridge for polishing heads;
– the ability of the tool to absorb and release process fluids;
– drying time of the process fluid;
– head pressure;
– control and management of the operating temperature generated by tile/tool friction.
SuperShine is based on the use of 10 satellite heads Æ 580 mm with 6 tools Æ 160 mm, each of which applies an adjustable amount of natural silica in fluid suspension that is pressed by the force and weight of the heads themselves. Specifically, the first 7 heads have the function of spreading and polishing the product, while the following 3 are for washing. The result is continuity in the quality of the finished product.
Thanks to all its technical and technological features, SuperShine can be defined as a real dry super-polishing process.
