First, the management and use of equipment The high-load use of instruments and equipment is often prone to accidental failures. In particular, if optical instruments are fogged due to improper maintenance and use, they cannot function properly and cause obstacles in their work. Therefore, efficient maintenance of management equipment has become an effective means for enterprises and institutions to effectively reduce costs and increase labor productivity. At present, domestic enterprise equipment maintenance management generally stays in the passive repair operation mode, that is, when the equipment and equipment fail and cannot be used continuously, the maintenance personnel will eliminate the fault in the shortest time, and when there is no fault, the maintenance personnel are only idle. Therefore, such a management model is not efficient. Therefore, the management of equipment and equipment should also be planned. Similarly, equipment maintenance management needs to transform unplanned work into planned work. If we regularly check and maintain to reduce the occurrence of faults, especially to do the "three defenses" of the instrument, to avoid repair work, and to ensure that the instrument can be put into normal function at any time, this is a proactive approach. Second, the maintenance of photochemical instruments In the manufacturing and maintenance process, pay attention to the clean production, assembly and maintenance of the workshop must be clean, and strictly follow the operating procedures, carefully wipe the optical parts, direct contact and take optical parts directly by hand, tools for holding optical parts must be degreased The accessories used to wipe optical parts, such as cotton, cloth, ethanol, ether, iodine, and organic gaskets in contact with optical parts, must be strictly degreased to control the amount of fat, the vessels containing optical parts, and ethanol. Bottles of ether, which must be cleaned frequently and kept clean, are important ways to reduce oily fog. Reduce the water vapor inside the instrument, prevent the water vapor from condensing on the glass surface, assemble as much as possible under dry conditions or dry the assembled instrument, such as dry nitrogen or air and place the desiccant. In the use and inventory of the instrument, try to control the relative humidity of the use environment and the warehouse is about 6%. It is not good for the external instrument to control the humidity during use. After use, it should be placed in a ventilated, sunny and dry place in the instrument box. Put in the desiccant, and pay attention to sealing and timely replacement of the drying silica gel desiccant, in the humid environment, the use of internal instruments, such as corrector, revisiting instrument, etc., for the lens and precision optics that can be taken down, after use Take it down and put it in a dry cylinder for protection, and keep the instrument clean and reduce the core of fogging. Third, the cause of fogging of optical instruments and its harm Fog refers to the polishing surface of optical parts, which exhibits the appearance of "dew". Some of these substances are composed of oily dots, called oil mist, and some are composed of water droplets or water and glass to form a chemical reaction. It is called water-based fog: on some optical parts, there are two types of fog, called water-oil mixed fog, which are generally present on the glass surface in the form of "dew" or dry deposits. Oily fog is usually distributed at the edge of the optical optics and extends toward the center, while some are distributed along the wiping marks. The formation of oily fog is mainly caused by oil contaminating the surface of the glass, or due to the diffusion of grease, volatilization on the surface of the glass. The resulting materials, such as the wipes used to wipe optical parts, have high fat content, or the tools used are greased, and the direct use of fingers to touch and touch optical parts can cause oily fog or chemical stability of the grease used on optical instruments. It is not good, the diffusion or the method of use is not too much oil, the oil spreads to the optical parts and causes oily fog, or because the oil of the meter is very volatile, it will produce oily vapor to form oily mist, and some will be cleaned with gasoline. When the metal parts are not fully cleaned, the oil is assembled. In addition, the dust is diluted with gasoline and applied to the lens body. As time goes by and the temperature changes, the gasoline and other components are gradually volatilized onto the optical parts to form an oil mist. Fourth, the method of using anti-fogging agent The use of ethyl hydrogen-containing dichlorosilane to treat chemically permeable double-coated and uncoated optical glass parts can form a relatively strong film layer, has hydrophobic properties, has good waterproof fog performance, and is easy to form and coat at the same time. The surface of the optical parts can improve the mechanical properties of the glass, protect the glass surface from scratches to a certain extent, improve the chemical stability of the optical glass surface, use it to clean the glass, and has strong decontamination ability, and it is easy to remove the fingerprint. The saliva circle improves work efficiency, which is a good anti-fogging agent. When used, the concentration of ethyl hydrogen-containing dichlorosilane is 0.25%-1% (% by weight). It is formed into a film at room temperature and solidified quickly. The cleaning method can be used. Easy to use and no need to add equipment. However, it should be noted that ethyl hydrogen-containing dichlorosilane has a pungent odor. Do not touch the skin and clothes during preparation. Use cotton balls or sponges when rubbing, do not touch the metal, if used for uncoated and unlined optics. The concentration of the parts can be increased to 4%. Since the ethyl hydrogenated dichlorosilane acts as a corrosive action after water or moisture absorption, it should be sealed and stored to prevent corrosion of glass and metal. Currently used. Phosphate glass should not be treated in this way. It can also be used as anti-mold and anti-fog agent, p-nitrophenoxyethyl hydrochlorosilane, which is a brown liquid, which is easy to be hydrolyzed. The drug is mixed with diethyl ether to form a solution of about 5% concentration, centrifuged, soaked, The wiping method can be formed into a film. In addition, the use of ethyl hydrogen silicone oil and lauryl trimethoxysilane antifogging agent can effectively prevent fogging. V. Summary Due to the rapid development of science and technology and the needs of the development of the world economy, new scientific and technological achievements are continuously applied to instruments and equipment, the level of modernization of equipment is constantly improving, and modern equipment is developing in the direction of high speed and precision automation. Introduce theories and methods of modern modern instrument and equipment management, explore ways to catch up with the international advanced level, and make the management of optical instruments and equipment into a healthy modern management stage.
