Classification of degumming agent and matters needing attention in use

Degumming agent is a common building material, which can effectively remove all kinds of glue. However, different types of degumming agents need to pay attention to different matters when using. This paper will introduce the characteristics and matters needing attention of deacetylation, dealcoholization TC and deacidification degumming agent.

Pungent and unpleasant

Deacetate degumming agent will release acetic acid during curing, which is irritating and unpleasant, and will cause corrosion risk to metals, coated glass and inorganic materials. Pay attention to protect the surrounding materials and equipment when using.

High temperature construction

Dealcoholized TC degumming agent needs to be constructed at high temperature, which is too fast, and alcohol molecules are difficult to disperse, forming bubbles, which affects the construction technology. Pay attention to the temperature and humidity of the construction environment and the rationality of the construction technology when using it.

Not suitable for cement and stone.

Deacidification degumming agent is an acidic glue, which is not suitable for cement and stone. After curing, acetic acid is released, which is easy to fall off. The material has large expansion coefficient, large displacement or vibration, too thin construction, and the surface of neutral glue is easy to wrinkle after curing; When used with acid glue, neutral glue may turn yellow. Pay attention to the selection of suitable materials and construction environment when using.
