How to judge the water resistance of fiberglass tubes for induction heating furnaces!

Fiberglass Tube for Индукциялық жылу пеші

Because it is difficult to avoid water or water vapor in the natural environment of glass fiber selection, the water resistance of glass fiber pipes for induction heating furnaces is a key factor that must be considered. A reasonable and effective evaluation of the transformation of glass fibers in water environment will help guide glass fibers. Product selection and development.

There is no relevant report on the water resistance test of glass fiber pipes for induction heating furnaces at this stage.

Generally, all countries in the world use a fixed volume of water for immersion tests at the corresponding temperature for water resistance testing, or boil the samples in a fixed container. This method is possible for glass samples.

However, the choice of this method for glass fiber tubes for induction heating furnaces is debatable, because the surface area of glass fiber tubes for induction heating furnaces is relatively large, and the alkali ions dissolve after the hydrolysis reaction between glass fibers and water, which will cause water The environment becomes alkaline due to the completion of the hydrolysis reaction, resulting in further alkali corrosion. The water resistance of glass fiber tubes for induction heating furnaces is based on the hydrolysis of water and glass fibers. The test results can no longer be simply conceptualized as water resistance. sex.
