usage temperature
1.Oxidized on reaction conditions with H 2 O 2 usage of 20%, temperature of 90 ℃, reaction time of 1 h and O 2 pressure of 0.4 MPa, the oxidized lignin had the highest content of acid soluble lignin.
2.USAGE: AS ADDITIVES OF TITANIUM ALLOY, HIGH -TEMPERATURE ALLOY AND SOME SPECIAL ALLOYS.
4.during the course of methylation, the usage of dimethyl sulfate is 1.00(mol ratio), the usage of sodium hydroxide is 1.20(mol ratio), methylation temperature is 85?, the reactive time is Shours;
5.The resulted primary liquid of sucra lose was decolorized by pulverous active carbon. The optimized process conditions were as follow:the usage of active carbon5%,decolorization time 30min,and deco lorization temperature 60℃. The efficiency of decolorization wa s 92.4%to 94.1%and the loss of sucralose was only 5.7%to 7.9%。
6.DS18B20 is the digital temperature sensor product of Dallas cooperation of USA. The characteristic and the usage of DS18B20 were introduced.
7.The connection between the thickness of liquid fuel layer and the filling temperature and gas press is given by usage of BWR equation.
8.For the chemical furnace at tail of which the serioussuperhigh temperature occurred, the temperature distribution andheat conducting condition in the furnace are greatly improved by using spiral flow combustion technology with multi-ejector-nozzles, so that the superhigh temperature problemis resolved thoroughly as well as the thermal usage in the fur nace is increased by 10% in the result of energy saving .
