In many industrial production scenes, such as food processing, textile printing and dyeing, chemical synthesis and other workshops, due to the needs of the production process, the environmental humidity is at a high level for a long time. In this high humidity environment, the accuracy and stability of the measuring equipment are faced with severe challenges, and the deformation of the equipment is frequent, which seriously affects the production quality and efficiency. The emergence of granite components with moisture resistance provides an effective solution to this difficult problem.
Analysis of the influence of high humidity on measuring equipment
Corrosion and deformation of metal parts: Common measuring equipment mostly contains metal materials, and in a high humidity environment, the metal surface is easy to absorb water vapor to form a water film. Taking steel material as an example, the water film reacts electrochemically with oxygen, carbon dioxide and other substances in the air to produce rust. The volume expansion of rust will cause deformation of metal parts and decrease dimensional accuracy. In the high-humidity electroplating workshop, the metal caliper used to measure the size of the plated parts may not be smooth due to corrosion in just one week, and the measurement accuracy deviation is more than 0.1mm, and the original measurement error range of 0.02mm is completely destroyed.
Electronic components damp failure: Electronic components in measuring equipment are extremely sensitive to humidity. When the humidity exceeds 60%RH, water vapor on the surface of electronic components may cause problems such as short circuit and leakage. For example, after the sensor in the precision electronic balance is damp, the output signal fluctuates, resulting in unstable weighing results, and the error can reach ±0.005g, which seriously affects the accurate measurement of the weight of raw materials and semi-finished products. In the pharmaceutical industry, this may lead to the imbalance of drug components, affecting the quality and efficacy of drugs.
Optical components mildew blur: For optical measuring equipment, such as microscopes, projectors, etc., high humidity provides a breeding ground for mold. Mold grows and multiplies on the surface of optical lenses, forming mildew spots that block light propagation and reduce imaging clarity. In high-humidity biological laboratories, the lens of the optical microscope may appear obvious mold within a month, and the originally clear cell structure image becomes blurred, interfering with the observation and analysis of the experimental results of researchers.
Unique advantages of moisture-resistant granite components
Natural moisture resistance: Granite is a kind of natural stone, its main components are quartz, feldspar and other minerals, dense structure, the gap between the crystals is very small. Water molecules are difficult to penetrate into granite, fundamentally preventing deformation caused by water absorption. After testing, in the relative humidity 95%RH environment for 1000 hours, the size change of the granite component is less than 0.001mm, almost negligible, providing a stable and reliable support basis for measuring equipment.
High stability and accuracy: After billions of years of geological processes, the internal stress has been fully released, with extremely high dimensional stability. Even if it is used for a long time in a high humidity environment, its key accuracy indicators such as flatness and straightness can still be maintained at a very high level. In the textile workshop, the use of wet-resistant granite platform as the benchmark for fabric flatness measurement, the flatness of the platform in the long-term high humidity environment is always maintained within ±0.005mm, to ensure that the fabric flatness measurement error is controlled in a very small range, to ensure the quality of textile products.
Strong resistance to chemical corrosion: high humidity environment is often accompanied by a variety of chemical substances, such as acidic gas, alkaline solution, etc., ordinary materials are susceptible to corrosion. The moisture resistant granite has stable chemical properties and excellent acid and alkali resistance. In the chemical workshop, even if there are strong acid and alkali reagents such as sulfuric acid and sodium hydroxide volatilization, the moisture resistant granite components will not be corroded, and the accuracy and service life of the measuring equipment will not be affected by chemical corrosion.
