The process of inorganic fiber spraying construction mainly includes: relevant preparation before construction → treatment of spraying base surface → spraying construction → surface trimming → cleaning of spraying site → quality acceptance → natural maintenance of spraying layer. The quality inspection of inorganic fiber spraying raw materials and observation also includes the following aspects: 1. Before construction, sampling inspection of sprayed fiber cotton and adhesive shall be carried out, and fiber cotton shall be dry and free of caking, white and free of dirt, adhesive should be free of stratification, foaming, deterioration and discoloration; 2. Treatment of spraying base surface (1). Treatment of spraying base surface: Use compressed air or clear water to clean up dust and dirt on spraying base surface; Check whether the hanging parts and embedded parts are firm, and fasten the loose parts. If the original base surface has been damaged or has serious cracks, repair should be carried out first. (2), the doors and windows and various equipment, pipelines and non-spraying parts of the shielding, blocking the spraying parts and ventilation pipeline through hole. (3), clean up the obstacles on the working surface, ensure the smooth movement of the spraying hand space and its safety, and maintain the best spraying distance and spraying angle. 3. Material preparation and debugging (1), break up the compressed fiber cotton, continuously fill the sprayed cotton into the spraying machine, and keep the fiber material in the material box sufficient. (2) A special person shall be responsible for diluting the adhesive stock solution with clean water in a professional matching container (a 200-liter graduated plastic container equipped with a high-speed stirrer) according to the instructions for spraying the adhesive. The preparation ratio shall be strictly controlled, and the water dilution shall not be increased at will. The electric stirrer shall be continuously started for uniform stirring. The stirring time shall not be less than 5 minutes. Each barrel shall be prepared one by one, and prepared as required to avoid freezing and failure. 4. Pre-spraying primer on the surface of the base layer: after the surface of the base layer is cleaned, the prepared spraying adhesive can be used to pre-spray glue on the base surface. The glue amount is appropriate and uniform without flowing.
