Large and small reject parts and sprues typically accumulate in the injection moulding machine and must be fed back in. The same applies to the blow moulding machine, with blebs and start-up tubes as well as reject parts. The grinding process can be carried out directly next to the moulding press or at a central location in the plant.

A simple electrostatic model has been used to demonstrate that the inner surface hydroxyls in kaolinite, dickite and nacrite are responsible for the interlayer bonding in these minerals. The contribution to the interlayer bonding of an individual hydroxyl hydrogen depends on the orientation of the hydroxyl group relative to the 1: 1 layer since this orientation determines the …

Jul 1, 2024 · La fraction de particule de 0,2 à 5 μ de montmorillonite provenant de trois sources différentes a été équilibrée avec des solutions variées à la température ambiante. Trois ou quatre ans après, de la kaolinite a été trouvée dans certains échantillons qui étaient supersaturés par rapport à la kaolinite, mais pas dans les échantillons sous-saturés ou dans la montmorillonite d ...

Aluminum ions as well as hydroxide precipitates promote improved extraction of iron from kaolinites during leaching. Selective aggregation of ultrafine particles in kaolinites, seemingly induced by precipitation of aluminum hydroxide, gives brightness improvement in excess of that which can be ascribed to iron extraction. Aggregation of anatase, a primary discolorant …
