Mixing
Effect of accelerator mixing ratio on curing characteristics of EPDM gasket materials
In a four-person household, the washing machine is in operation about one and a half hours a day. On average, it washes, rinses and spins about 250 times a year, cleaning some 1,000 kilograms of dirty laundry, an amount that is increasing all the time. Its components, particularly the rubber hose systems and rubber gaskets, are subjected to greater chemical and mechanical stresses than just about any other household appliance. Moisture, detergents and cleaning agents, particularly alkaline agents, as well as high water temperatures must not have an adverse effect on the material. Due to the long service life of the washing machine, all polymer parts, especially rubber parts, need to have a service life of at least 10 years, which means excellent resistance to aging.
Chemicals and Materials
Multi-purpose additives for rubber compounds
Several products that can serve more than one purpose in rubber compounds are examined, including anti-reversion agents, dithiophosphates, curing activators and blowing agents.
Extrusion
High efficiency twin screw extruder
The demand for performance and consistency of elastomer based compounds is growing quickly in all fields (tire, technical rubber goods, cables). Specifications regarding physical, mechanical and chemical properties, as well as “visual aspects” properties of the finished products are becoming more and more strict.
During compound production, all operations are involved, from the weighing to the storage of the semi-finished mixed compounds. The mixing operation plays a very important role, since it is the step where all ingredients are incorporated, dispersed and distributed.
