What are the methods for collecting and purifying flue gas in mechanical processing plants? Please be sure whether it is soot or oil mist.If it is soot, it can be judged that the anti-soot resistance of cutting oil is too poor,Please choose a product with low oil fume,The cause of the fume is actually too poor in abrasion resistance,Lubricating Oil occurs during tool and workpiece grinding because of high speed.The machine tool processing parameters can also be adjusted appropriately.In addition, we should pay attention to the fact that cutting oil is not a quality problem,In addition, we also choose products according to the material you process, the speed of the grinding wheel of the tool, the amount of feed, the machine tool, etc,If the viscosity is not good, there must be a problem.If the oil and gas can be adjusted through the machine tool parameters,A small amount of oil and gas is normal.If the fume is large,Please pay attention,First, it is not good for health,Two is the consumption of oil will be ver
At room temperature, an element is formed into a powder-like solid, which is easy to melt. the element burns in oxygen and emits a blue-purple flame. 5 This element is sulfur,Sulfur burns blue and purple in oxygen,At normal temperature, it is a summary of powder junior high school chemistry. 1. chemistry is an experiment-based natural science that studies the composition, structure, nature and change law of substances.What physics and chemistry have in common: natural science based on experiments.2. the fundamental difference between chemical change and physical change is whether there are any new substances.Some phenomena such as heat release, light emission, discoloration, gas release and precipitation occur in chemical changes.3. physical properties--State, odor, melting point, boiling point, hardness, density, extensibility, solubility, volatility, conductivity, adsorption, etc.4. chemical properties--Oxidation, reduction, metal activity, activity, stability, corrosiveness, toxicity, etc.5. after heating
