Microbiological method for securing archival and museum objects and installation for microbiological protection of archives and museum objects

摘要

the identified hazard microbiological and subsequently secured objects coincide nanoczu0105stkami metals biocidal action, especially nanoczu0105stkami silver. in the process of affixing metal nanoparticles using colloidal solutions of these metals and the process chamber (1) with forced air circulation and temperature and humidity controlled.after placing the object in a hedged process (1) in the first stage shall be subjected to microbiological material identified in the substrate incubation hedged object to allow the spores and spores of microorganisms, while the air humidity the feed to the process chamber (1) is gradually increased by dispersing the particles in deionised water.in the second stage, the hedged item is exposed to the air stream containing metal nanoparticles, especially silver, medium size in the range of 10 30 nm, which is the metal nanoparticles is by dispersing colloidal metal micro droplets of an aqueous solution a stream of air supplied to the process chamber (1).in the third stage of the hedged item shall be aged in the air stream of the gradually varying parameters until after her time, humidity and ambient temperature.the installation consists of a process chamber (1), the liquid dosing system of trial, the recirculation fan (8), a channel (3), a temperature regulating unit, sensors to control humidity and temperature, and control system for regulating the process parameters.the team includes two pairs of sensors sensors (6, 7) to control the humidity and temperature, the first of which is placed in the recirculation channel (8) for entry into the process chamber (1), and the other is placed in the recirculation air (8) at the outlet of the chamber process (1).between the second pair of sensors (6, 7) and kanau0142owym fan (3) is connected with the throttle inlet channel (9) and the radiator (2), between the fan kanau0142owym (3) and (4) is connected nagrzewnicu0105 channel outlet (10) of a throttle, and between nagrzewnicu0105 (4) and pi erwszu0105 couple sensors (6, 7) are placed in two separate circuits dosing system.the first (5) and the second metering deionised water (5 ') for dispensing aqueous solution of biobu00f3jczej, especially silver colloidal aqueous solution, each metering circuit (5, 5') has a separate spray nozzles located inside the recirculation channel (8).
