- Q: What is the usage of aluminum sulfate for every ton of paper produce for kraft paper and news print
- Aluminium sulphate was the most extensively used chemical raw material in the papermaking industry. Its primary use was in the rosin sizing of paper where the rosin soap was reacted with aluminium sulphate to impart hydrophobis characteristics to the paper. The alum had a side benefit in fixing all types of anionic substances into the paper web. All types of paper, even those that were not sized, such as newsprint,were made using alum. This resulted in the paper being made under acidic conditions. The technology has changed markedly over the last 10 to 20 years with synthetic sizing agents being developed which do not require reaction with alum. In my country there is not 1kg of fine writing and printing paper made with rosin/ alum sizing, and no alum is used at all. Various synthetic highly charged cationic resins have been developed, such as polyacrylamide resins, polyethyleneimine resins, etc, whic are used as fixing and retention agents, so that alum has been virtually eliminated. To sum up the importance of aluminium sulphate as a papermaking chemical is now very limited.
- Q: How do aluminum sheets perform in terms of thermal conductivity?
- Known for their excellent thermal conductivity, aluminum sheets are highly efficient in transferring heat due to having one of the highest thermal conductivity among common metals. This quality enables aluminum sheets to rapidly absorb and distribute heat, making them ideal for situations where heat needs to be dissipated or transferred quickly. Furthermore, their high thermal conductivity guarantees even heat distribution across the surface, reducing hot spots and improving overall heat transfer efficiency. As a result, aluminum sheets are widely acknowledged for their exceptional thermal conductivity, making them a favored option in industries such as automotive, aerospace, and electronics.
