Continuous coating line
Fabric width up to 600 mm, max. coating thickness 1 mm, drying temperature up to 250°C. Laboratory line for coating and impregnation enabling continuous treatment of fabrics with aqueous or solvent solutions of natural or synthetic rubbers, polyurethanes, silicones. The line is equipped with controlled fabric unwinding/rewinding, a 3-stage drying chamber, a guiding device, and separation insert unwinding. Coating is possible with a knife against a fixed roller or with a suspended knife; 3 types of knives with different geometries are available. The impregnation tank is equipped with a submersible roller, and wringing is ensured by steel rollers with adjustable pressure.
Laminating coating line
Rubber compound application line, for material tests max. width 600 mm, maximum thickness 30 mm, temperature of rollers for compound tempering up to 180°C.
Laboratory 3-roll application line for continuous application of rubber compounds on textiles. The line is equipped with controlled unwinding/reeling of fabric and separation liner, guiding device, cooling is provided by drum cooler. The supply is done manually with preheated rubber compound. The arrangement of the coating rollers is half Y.
Vulcanizing autoclave
Grate autoclave with a maximum vulcanization temperature of 180°C and a working pressure of up to 5 bar for
vulcanization of mixtures.
The development center has its own two-speed mixture mixer with a capacity of 100 l of solution, maximum mixer speed of 2000 rpm, for mixtures with a dynamic viscosity of up to 250,000 mPa·s.
Laboratory evaluation of samples
GUMOTEX provides tests of raw material - initial tests of substrates, rheology of rubber compounds, formulation, substrate preparation. Evaluation of finished product properties - especially functional performance: resistance to specific chemicals, resistance to climatic degradation, flammability, electrical conductivity, water column, adhesion and verification of production parameters (textile and compound adhesion, coating thickness).
Ozone chamber
The development samples can be tested for resistance to natural ageing under static deformation with variable temperature of 23-70°C at relative humidity of 30-80%. The material can be loaded with ozone concentrations ranging from 10 ppm to 1000 pphm.
