The important measures to avoid cracking of composite air duct are as follows

We hope to make you more efficient and long-term application of the composite air duct through our introduction. Let's have a specific understanding as follows:

In view of this knowledge, we should know that for the composite air duct, it is necessary for our technicians to select the special glue to manufacture and install the air duct. The special adhesive for group A and group B distribution is called two-component adhesive. Magnesium oxide and brine can not be used as adhesive, so it must crack. The special adhesive is made of magnesium oxide as the main raw material, nylon short fiber, water resistant agent and water retaining agent, which are mixed together to form powder (group A); in the field, magnesium chloride is mixed into a brine (group B) with Baume degree of 24be ~ 26be. Group A and group B are mixed and distributed in the field to form a special glue in the form of fluid.

In addition, we should also note that the air duct board quality of the composite air duct should reach the technical indicators specified in the professional specification of glass magnesium composite board air duct: the bending load is greater than 1200n, the softening coefficient is greater than 85%, the content of free chloride ion is less than or equal to 3, and there is no representation of returning brine.

I hope that the above knowledge about composite air duct can make you better understand and realize this knowledge. We will continue to bring you more knowledge about this. Please look forward to it
