Glass washing machines

The uses in the glass and ceramics industries reflect the diagonal relation between boron and silicon and the similarity of vitreous borate and silicate networks (pp. 203, 206 and 347). In the UK and continental Europe (but not in the USA or Japan) sodium perborate (p. 206) is a major constituent of washing powders since it hydrolyses to H2O2 and acts as a bleaching agent in very hot water ( 90°C) in the USA domestic washing machines rarely operate above 70°, at which temperature perborates are ineffective as bleaches. 

Calcium can deposit out of water to leave scale on surfaces, such as kitchen worktops and glass in the bathroom, or in dishwashers and washing machines. 

The desired bottles then proceed to the grinder and the washing machine. The ground plastic is washed to remove product and labels. The paper labels sink and the HD PE is floated off the top and conveyed to a drier. Contaminants such as glass and metals also sink and are discarded with the paper labels. After the material is dry, it can be boxed or extruded and pelletized. Color or additives can be added to the resin prior to extrusion if necessary. 

Contaminated swatches that were pre-rlnsed were placed Individually In 500-ml glass jars with distilled water and agitated on an Eberbach mechanical shaker to simulate the pre-rlnslng cycle of an automatic washing machine. 

A new plastic pulley, a cost effective replacement of a cast aluminum counterpart, is now used in all Hotpoint washing machines. The injection molded pulley, made of DuPont glass fiber reinforced Zytel nylon resin offers lower part cost vs. casting, without compromise in mechanical properties. The pulley was designed and manufactured by Rolinx Plastics Co. Ltd., UK, in conjunction with appliance maker Merloni UK...

The stiffness of common plastics materials is very low compared with steel (flexural modulus of most common thermoplastics 2 GN m 2, modulus of steel 200 GM m"2). Glass reinforcement greatly increases the stiffness of plastics, both thermosetting and thermoplastic - see Philips glass-coupled polypropylene washing machine tank. Chapter 9. For example, the flexural modulus of cast unsaturated polyester resin 3.5 GN m 2, flexural modulus of GRP (glass reinforced polyester resin) SGM m"2.
