Saponification

แปลว่า(Concrete Engineering) The deposit of a gray scum or gray dust on the inside surface of a subgrade wall or floor; as the result of moisture moving through the concrete and washing certain chemicals from the concrete mass.

Secondary treatment

แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

Blow Back

แปลว่า(english) A coating defect consisting of a lower coating film weight on the bottom of the coated sheet caused by high velocity air in the oven. Blow back usually occurs with high solids coatings which have little solvent to evaporate and "set" the film.

Toxicity

แปลว่า(Environmental Engineering) A U.S. EPA hazardous waste characteristic defined with a rigorous test procedure, the TCLP (for Toxicity Characteristic Leaching Procedure). In the procedure, a waste is extracted for 24 hours with an acetic acid solution. The acid extract is then analyzed for the presence of any of the contaminants listed in the procedure.

Project planning

แปลว่า(Software Engineering) the activity that creates the Project Plan

Z-Mill

แปลว่า(english) The full name for z-mill is Sendzimir mill. A Z-mill operates with a very small diameter work roll, normally about 2 inches, backed up by a number of rolls in a pyramid-shaped stack. This roll set up allows you to exert extremely high forces through the work roll and yet keep the work roll from extreme flexing. The take-up roll on the Z-Mill also exerts a tension on the coil as it comes through the mill. The combination of high pressure and tension makes the mill capable of rolling material thin and flat.

Bottom Die

แปลว่า(english) The stationary half-die.

Water Vapor Pressure

แปลว่า(Concrete Engineering) The pressure exerted by water vapor. Air that contains higher amounts of water vapor exerts a higher vapor pressure than air which has a lower amount of has a higher water vapor pressure In concrete water vapor pressure is calculated by the difference between the vapor pressure of the concrete and the ambient relative humidity and temperature and in contact with the soil. that is calculated by; based upon relative humidity and temperature. The greater the difference between the water vapor and ambient humidity and temperature, in degrees Fahrenheit. the greater the water vapor pressure exerted.

Suspended growth reactor

แปลว่า(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.

Blacking Hole

แปลว่า(english) Irregular-shaped surface cavities in a casting containing carbonaceous matter. Caused by spilling off of the blacking from the mold surface.

Bloom 2

แปลว่า(english) A semi-finished hot rolled product, rectangular in cross section, produced on a blooming mill. For iron and steel, the width is not more than twice the thickness, and the cross-sectional area is usually not less than 36 sq. in. Iron and steel blooms are sometimes made by forging.

Back-up Roll

แปลว่า(english) 1) Roll used as a support roll mainly for plater rolls. 2) Two rolls, one on top and one on bottom of the two work rolls which apply pressure and reduce the flexing of the work rolls.
