Title:
METHOD FOR UTILIZING FLUORESCENT MATERIAL TO EXPRESS CHANGES IN HUMIDITY OF BONDING MORTAR
Document Type and Number:
WIPO Patent Application WO/2021/164242
Kind Code:
A1
Abstract:
A method for utilizing a fluorescent material to express changes in the humidity of a bonding mortar, where a rhodamine microcapsule is placed in the bonding mortar, during a work period in which the bonding mortar is in service, an infrared-transmitting camera is utilized to photograph in real-time the fluorescent intensity of rhodamine, thus expressing the state of humidity of the mortar. The infrared-transmitting camera is capable of photographing the actual fluorescent intensity of rhodamine at a testing phase, the state of humidity of the mortar is expressed on the basis of the fluorescent intensity of the rhodamine photographed, and comparison is made with respect to the humidity of the mortar at different points in time to acquire changes in the humidity of the mortar. The method expresses changes in the humidity of the mortar via the humidity sensitivity characteristic of rhodamine, is convenient and quick, and provides a great visual effect; by bearing a rhodamine B reagent with a TPU waterproof and breathable membrane, the stability of the rhodamine B reagent is significantly ensured.
