Since taking some measures,for example decreasing the specific area of furnace charge,controlling charging sequence,improving removing slag operation,etc,the melting loss of aluminium alloy is decreased from 30% to 1.6% in Zibo aluminium plant.
Past two years'operation shows that, in the furnace which uses bottom fume offtake, the furnace pressure at the charge door remains zero or slightly below zero and that compared with other 650 blooming reheating furnace the fume offtake temperature at furnace rear is reduced by 200~-250℃.
According to caloric requirement of heating rural house in Shandong Province in winter, a heating furnace with the size of 33 cm×46 cm×45 cm for biomass smoldering was designed and set up.
To improve the yield of β-glucanase by Bacillus amyloliquefaciens 5582, the fermentation techniques were optimized in laboratory. In a 5L fermentor, the optimal fermentation conditions were: 60% medium volume, 6.67% inoculum, 18 h-cultured seed, aeration 1.0 L/(L·min), stirring at 500 r/min, initial temperature of 36℃. The fermentation temperature was decreased to 32℃ after 27h cultivation and kept to the end of fermentation.
The charge transfer between the dinitrobenzoyl ligand and the analytes plays a significant role in the separation of phenols and naphthalene derivatives.
Reactive diluents such as phenyl glycidyl ether and cyclohexyl glycidyl ether (CHGE) influence the cure time and the network formation of the final crosslinked product.
