Using humic acid extracted from Sinkiang Hami brown coal as raw material,and acrylic acid and acrylamide as monomer,PSA-AM polymer was synthesized by the method of solution copolymerization.Based on PSA-AM,a new super absorbent polymer was synthesized through adding humic acid and fly ash.The new polymer had well capacity of retaining and…[Read more]

Backpacking gear is basically used as a cloth sack carried on one s back and secured with straps that go across to support the shoulder. Backpacks are generally used to carry luggage and ensure that they are an important element to be used as hiking gear. The logs are shredded or ground and placed in various sorts of driers.

This extraction procedure was compared with the Japanese official method in which samples were dehydrated with 75 g of anhydrous Na2SO4 and extracted with ethyl acetate. Food homogenate (10 g) was mixed with 5 g of polymer, and the mixture was extracted with 75 ml of ethyl acetate using a high speed homogenizer. Unlike that of anhydrous Na2SO4…[Read more]
