แปลว่า(english) 1) Regular galvanize coating (not minimized spangle or JP). 2) Rolls that have no grit; smooth finish on surface of steel.

Burnt Rubber

แปลว่า(english) Small or large black spots that generally show up on surface and are generally caused by pickling steel too hot.

Backer (back-up plate)

แปลว่า(english) A “tool” or reinforcing part, which presses against the outer surface of an extrusion die, supporting it against the pressure of the extruding metal. The backer has an opening larger than the die aperture, allowing the extruded product to emerge without marring its soft surface.

Rebound

แปลว่า(Concrete Engineering) Wet shotcrete or sand and cement which bounces away from a surface again at which pneumatically applied mortar is being projected.

Abrasive Wear

แปลว่า(english) The displacement and / or detachment of metallic particles from a surface as a consequence of being exposed to flowing fluids or gases.

Distributed load:

แปลว่า(english) An external force which acts over a region of length, surface, or area: essentially any external force which is not a concentrated force.

Condensation

แปลว่า(Concrete Engineering) When a moisture laden gas comes in contact with a cooler surface a change of state from gaseous to liquid occurs.

Biofilm

Brinell Hardness Test

แปลว่า(english) A common standard method of measuring the hardness of materials. The smooth surface of the metal is subjected to indentation by a hardened steel ball under pressure. The diameter of the indentation, in the material surface, is then measured by a microscope and the hardness value is read from a chart or determined by a prescribed formula.
