athe chemistry of the setting action of portland cement is very complex,but it may be stated simply that seting is due to the combination of the mixing water with the various chemical compounds of lime and clay produce by the high temprature to which the raw materials are subjected during ma...
Herbal medicinal products would be affected by the quality of raw materials. In turn, the quality of raw material will also be influenced by various factors such as soil conditions, cultivation, post-harvest processing, and the processing of raw materials into crude drug or extract. Therefore, ...
claim will let the moisture to get in. Crosslinks produced through the condensation chemistry require moisture for the crosslinking. The present invention relies on peroxide crosslinks through the use of silane grafted polymer that is free of moisture during the process and after the product is ...
