This article examines the evidence for fragmentation practices on Middle–Late Bronze Age (c. 1600–700 bc) settlement sites in Ireland by looking at two kinds of material: human remains, both burnt and non-burnt, and quern stones.It highlights evidence for the manipulation of non-burnt skulls through ‘de-facing’ and the potential retention of cranial and other fragments for ‘burial ...
Hard clay and soft clay are basic descriptions of the result of adding these fillers to rubber. Akrochem’s hard clay, HC-75, is composed of greater than 90% particles less than 2 microns. Thus it is more reinforcing and results in a higher durometer (rule of thumb is 4-5.5 phr per durometer point increase), higher modulus, tear, and tensile
Le procéde consiste à couler un insert dans un premier moule, à disposer l'insert ainsi coulé dans un second moule et à couler la pièce dans ce second moule autour de l'insert. La pièce d'usure ainsi coulée comporte avantageusement un insert à haute résistance à l'usure tandis que le reste de la pièce est en un matériau plus ductile résistant aux sollicitations mécaniques.

Mar 09, 2010· Clay bars are abrasive. This is how they work. They can/will remove the top most coating with repeated use. They will wear the paint, if used enough. Most of the time, claybar use is only removing a clear coat's embedded debris. Frequent "turning" of the clay must be done, or the debris will build and scratch the coating.
