To confirm the method, a collection of autogenous shrinkage and compressive energy of concrete with and with out super absorbent polymer (SAP) had been evaluated in contrast with the strategy proposed previously. 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 brand new super absorbent polymer was synthesized by means of…

However, there may be little information on the effect of border irrigation measure co-utilized with super absorbent polymer on the forest-tree plantation. A lot or too little of the polymer dosage all led detrimental effect on photosynthesis and transpiration of the plants. The super absorbent polymer (SAP) with an awesome prospect,as a kind of useful polymer,are widely used in lots of field. 3.0%, the neutralization diploma of acrylic acid is 75%, reaction temperature is 40℃. Under…

The effects of super absorbent polymer on maize root growth and its water absorption traits were explored using stable deuterium and oxygen isotopes. The outcomes showed that the appliance price of 75 kg/hm2 had a relatively large impact on the soil moisture from seedling survival stage to rosette stage of flue-cured tobacco, while the treatment with software rate of 60 kg/hm2 had a comparatively larger impact on soil moisture from flourishing growth stage to after maturity stage.…

At the identical time, the metabolic quotient was lowered by the I60S remedy, demonstrating 5.96%, 8.84%, 11.72% and 4.78% decreases, respectively. All the identical consept. 26. Roustaie, K., Movahhedi Dehnavi, M., Khadem, S., and Owliaie, H. 2012. Effect of various super absorbent polymer and animal manure ratios on the quantitative and qualitative characteristics of soybean below drought stress. 2013. Effect of super absorbent polymer, animal manure and potassium on the…

The physical and chemical properties of substrates amended with 1(S1), 2 (S2) and 3 g.L-1 (S3) SAP have been studied, with the substrate without SAP addition (S0) used as management. However, SAP addition at 1% price was able to alleviate the unfavourable impact of water depletion on Chinese cabbage. It is very important estimate the IC water by calculating chemical shrinkage precisely, and then the extra water is used to fill the space left by chemical shrinkage. The quantitative…
