Analysis of Causes of Unstable Humidity in Artificial Climate Boxes
Artificial climate box is a kind of environmental equipment with temperature and humidity control, which can simulate artificial environment. It is a very important environmental equipment in many experiments. Humidity is one of the regulation items of the artificial climate box. Generally speaking, according to the requirements of the experiment, the artificial climate box needs to be able to set different humidity, which requires that it needs to have a certain range of humidity control, including the artificial production of Top Cloud Yunnong. The humidity control range of the climate chamber is between 50 and 95% RH, and the humidity fluctuation is within ±5%RH. Such a humidity range can basically meet the needs of most environmental test jobs.
However, due to the large number of brands of artificial climate chambers currently on the market, there are large gaps in the technologies and materials used, which results in large differences in quality. Therefore, some artificial climate chambers will inevitably cause problems after long-term use. Artificial climate box humidity can not rise, just bought it can be up to 90%, but with use will find that artificial climate box no matter how to adjust the humidity can only rise to 70%, if such a problem, for the laboratory Operators are more annoyed, so it is necessary to analyze the reasons why the humidity in artificial climate cabinets cannot be upgraded, so that operators can check and deal with such situations.
First of all, artificial climate chambers can humidify and maintain a constant humidity environment in the cabinet, mainly relying on humidification pumps. In general, humidifiers have different qualities and their service lives are not the same, and the long-term use of humidification pumps may result in The power is not enough. At this time, it needs to be checked. If it is a humidification pump, it can be replaced in addition to the problem. In addition, the plugging of the pipeline will also cause the humidity of the artificial climate box to not rise. If the first step eliminates the problem of the humidification pump, it can be checked at this time whether the connecting pipeline is blocked. If so, do a clean run. However, if these two conditions are eliminated and the humidity of the artificial climate box is still not uplifted, it may be a malfunction of the equipment. At this time, we must contact a professional technician to deal with it. We must not open it for maintenance in order to avoid danger.
The pH value of Silica Sol is different. Silica sol is divided into basic silica sol and acid silica sol. Acidic silica sol is an important fine chemical. I don't know how much you know about it, and I don't know if you know what it does. Today, let's summarize the functions and characteristics of acidic silica sol.
1. The specific surface area of acidic silica sol is large, generally 150-300m2/g.
2. Acid silica sol has a strong adsorption: in silica sol there are many micelles of many open space with network structure under certain conditions for inorganic and organic matter has a certain adsorption.
3 acid silica sol has excellent temperature resistance: it can usually withstand the high temperature of about 1600℃.
4. Acid silica sol has good cohesiveness: because of its micelle uniform size, in about 10-20m/ U, dry air will produce a certain bond strength, but the strength is relatively small. If the acidic silica sol is added to some fibrous or granular material and then dried and cured, it will become a consolidated gel structure and produce greater cohesiousness. (Usually 46.7 kg/cm2)

5 acid silica sol has high dispersion, good wear resistance and excellent light transmittance, so it can be used as excellent dispersant, preservative, flocculant, coolant, etc.
6. In addition, acid silica sol has good hydrophilicity and strong hydrophobicity: can be diluted to any concentration with distilled water or deionized water, its stability increases with the increase of dilution. Oil repellent is produced when added to organic matter or a variety of metal ions.
Now, acid silica sol is mainly used in textile, electronics, refractory materials, solid state batteries and other categories. In addition, silica sol has been used in many industries and has benefited many production and living fields, bringing more pollution-free production to people. It can not only play a big role, but also ensure the normal existence of the environment
