Compared with the original simulator, the new simulator has been greatly improved in the following aspects: First, in the aspect of heat conduction, automatic temperature control is realized to ensure that the temperature in the kettle is consistent when the temperature is high and the temperature is constant. The simulation sample is consistent with the evolution of its products. Secondly, in terms of temperature control, by using the external temperature control and the internal temperature control method, the over-temperature phenomenon that may exist in the original instrument is completely avoided. The third is to reform the vacuum pump circuit. The automatic conversion between vacuuming and nitrogen filling is realized, and the operation is more convenient.
According to reports, the hot rock simulation test of source rock has been widely used in oil and gas exploration, especially in the study of organic matter evolution characteristics, oil and gas source comparison, source recourse and hydrocarbon generation mechanism and hydrocarbon migration. The use of hot-pressure simulation of source rock has given it unique results and rich information.
The successful development of the new conventional hot-pressure simulation tester is not only conducive to the popularization and application of this test method, but also because the simulation tester has the characteristics of accurately collecting and calculating the carbon number of liquid hydrocarbons from 6 to 14 fractions. It is of great theoretical significance to understand the hydrocarbon generation pattern of source rocks and to understand the geochemical change law of this fraction and the quantitative evaluation of the oil layer.
Yellow dextrin is also called yellow gum powder for short. It is mainly used in five industries:
1. In the grinding wheel industry, ceramic grinding wheel forming must use auxiliary materials.
2. Dextrin in medium and small casting industry (except for large resin sand mold), the oil sand core mold made by adding fat oil (Tonghu is better) is several times stronger than clay sand.
3. Casting bonding powder can be directly mixed with casting sand (with proper amount of water, without grease) to produce a core mold comparable to oil sand mold.
4. Dextrin can also be used as adhesive for adhesive tape for wood-based panel.
5. Dextrin is used as an additive for several exported dyes in the chemical industry.
In general, the viscosity of xanthodextrin is very low at normal concentrations. For example, if the DE value of xanthodextrin is 10-15, if the solid content is 40-50%, the viscosity is O 1P, viscosity increases with the decrease of DE value. The viscosity of low DE product with solid content of more than 40% can reach several pascals. This property change should be noted when using xanthodextrin.
