Paper/board is the largest single packaging material used in Australia, with about 36% of the total Australian packaging market, followed by plastics (30%), metal (20%), glass (10%) and other materials (4%).
Filters and strainers are used to remove pollutants and contaminants from water and other liquids, remove debris that could damage downstream equipment, and to help maximize manufacturing efficiency, as discussed in Filtration 101: Why Should You Filter Your Water For Manufacturing?.. Last week, we outlined several filtration and strainer technologies, so this week we're taking it a step
For this consider the acid-base indicators are selected by classifying different acid-base reaction of the titration in different groups as follows: 1. Strong Acid Titration. Eg. HCl + NaOH → NaCl + H2O. The pH at this type of reaction is 7 (neutral) because the salt doesn’t undergo hydrolysis with water.
Measurement variation consists of two important factors, repeatability and reproducibility. Repeatability is due to equipment variation and reproducibility is due to inspector or operator variation. Gage R & R can make known: The amount of measurement system variation compared with the process variation;
The selection of a particular material may be made based on the following. • Strength (material) properties (e.g. steel vs. wood). stout columns fail by crushing due to material failure. Failure occurs once the stress exceeds the elastic (yield point) limit of the • A factor K is used as a multiplier for converting the actual
