In one and all cases of receiving mix its structure is important very much. It is connected with the fact that the quantity of components for any given means, as a rule, is accurately regulated. And deviations from the standard can result in very deplorable results. Therefore it is very important to be able to define what any given mix consists of.
It is required to you
- - device for distillation;
- - flasks;
- - filter.
Instruction
1. If business concerns chemical mixes, then their structure, as a rule, is investigated empirically. For this purpose you need the device for distillation. Mix is located in special flasks. Then certain components are evaporated with simultaneous measurement of their volume. Other substances turn into a deposit and appear at the bottom of a flask. They need to be separated via the filter. Further on the basis of the turned-out values determine structure and amount of substances in the mix which is available for you by settlement chemical formulas.
2. If you need to define composition of mix of concrete, it is necessary to apply other knowledge. For more detailed analysis it is necessary to make concrete mixture from a part of the available mix. Such batch will help you to define quantity of basic components. So, for example, if concrete after drying too crumbles or pours, more sand, than cement means in its structure. And the stronger pours, the it is more than sand.
3. Experts can define also composition of mix for the carburetor. For this purpose it is necessary to start the vehicle and to pass on it a little, changing speeds and turnsof the movement engine. On these indicators you can make the first estimates of composition of mix. In case the speed and turns decrease, mix is used rich. Insignificant reduction of this indicator indicates that mix for the carburetor enriched. Grown poor it will be in case speed increases, and poor - when speed very strongly increases.
4. It is possible to check the determination of composition of mix also on color of a short skirt of the insulator of a candle. If it brown, mix either enriched, or grown poor. Dark points to excessive enrichment of mix. If you noticed light, almost white color, so mix on structure too grown poor.
