How to prevent and control microorganisms in museum showcases

How do microorganisms grow? Mold and mildew stains are caused by a variety of microorganisms that grow in the air. It is impossible for them to "grow" in well-ventilated environments with low temperature and humidity, and the objects can remain stable even if they are affected.

Large numbers of insects can infest museum collections, especially wooden objects. Wood boring punch or furniture beetles can penetrate furniture, prints, frames and anthropological wooden collections where they are extremely active and form causing structural damage. These insects can bore holes into the wood, leaving the outside with a thin shell, and then move on to the next piece of the collection. The particles they leave behind, called crumbs, are evidence of an ongoing attack. Formaldehyde, methyl bromide (methyl bromide) or ethylene oxide steam fumigation is usually used. Spot treatments can also be done using greening hydrocarbons and detergents formulated with a variety of insecticides. Borer diseases are primarily found in warm, unventilated environments, high humidity environments, and in wood with low resin content. Therefore, if it is a museum with relatively high collection value, it is recommended to use cold-rolled steel plate paint to make museum showcases.

Microorganisms usually thrive best in tropical areas with a relative humidity of 70% and temperatures above 15 degrees Celsius, in stagnant or enclosed environments, and on surfaces rich in cellulosic or protein-rich materials. They produce a common yellowish-brown stain on paper or fabric, but can also form colonies of various colors and forms on many surfaces.

When minor discoloration occurs and does not affect aesthetics, it may be sufficient to simply reduce the relative humidity and temperature and place the object in a well-ventilated area, which will allow the exhibit to stabilize. However, contamination may increase during long-term storage under tropical environmental conditions, and mechanical removal of spores and their by-products must be followed by disinfection and sterilization.

The traditional method of using thymol vapor to trap and kill microorganisms on prints, calligraphy and paintings is still in use today. Other fumigants such as formaldehyde vapor and ethylene oxide may also be used. Fumigation may also be used when anthropological collections, decorative objects, and industrial or agricultural products are subject to ongoing infestation by mold and fungi.

As long as it proves to be harmless to the material, a dilute solution of C6HCl5O (used as a wood preservative, herbicide, and sterilant) or a suitable volume of fumigant can be used for local treatment. Next, testing must be performed to ensure that the fumigation techniques and biocides do not leave harmful residues within the artifact or artifact. Operators must wear breathable protective clothing as most fumigation and sterilization materials are highly toxic.


To sum up, if you collect some valuable and fragile collections, you must pay attention to adjusting the humidity and temperature of the environment inside the showcase. It is best to make museum showcases with constant temperature and humidity. In this way, the collection can be better protected and protected from damage caused by the growth of microorganisms. If you have any questions or need further information about museum showcases or constant temperature and humidity machines, please feel free to contact our professional team. We look forward to supporting you and working with you to protect and showcase our precious cultural heritage.
