The board type can be flat, corrugated or corrugated.
IX. The Catalogue of Technologies Prohibited and Restricted from the Use of Housing Municipal Works (2022 Edition) was published.
In June, 1 10, 10 Catalogue of Technologies Prohibited and Restricted for Housing Municipal Works (2022 Edition) (draft for comments) was published. Non-alkali-resistant glass fiber mesh cloth shall not be used as auxiliary materials (prohibited), and alkali-resistant glass fiber mesh cloth shall be used instead. Inorganic lightweight aggregate thermal insulation mortar shall not be used as thermal insulation material for external wall thermal insulation engineering alone. It can be replaced by a fire-proof insulation board with good thermal performance.
