AI Technical Summary
Existing polyvinyl acetate adhesives can dissolve the salt pan structure, causing the soil structure of the entire soil specimen with the salt pan structure to be destroyed, thus losing its educational value.
The binder is composed of oil-based varnish and solvent. The oil-based varnish includes ester varnish, shellac varnish, phenolic varnish, alkyd varnish, nitrocellulose varnish, acrylic varnish, polyester ester varnish, fluorocarbon varnish, etc. The solvent is acetone, perchloroethylene, trichloroethylene, vinyl glycol ether, etc., with a volume ratio of (1-2):5. It is used for spraying and infiltration into soil samples. After drilling, the spraying is repeated 5-6 times.
It effectively protects the original structure of the soil vertical profile and the salt pan structure, ensuring that the morphological characteristics of the soil specimen remain unchanged, making it suitable for display and observation.
