Precautions for using insulation rock wool board

     4. Regarding the insulation of large-diameter and flat-walled equipment with rock wool finished products, when the temperature exceeds 200℃, be sure to keep in mind the instructions of the rock wool board manufacturer to add insulation nails.(Insulation nails distance is around 400mm). And the external protection should be tight.
     5. Appropriate coatings can be used for equipment, insulation nails, pipes that needs heat insulation. 
     6. When the temperature exceeds a certain temperature, such as 200°C, proper external protection must be added to the insulation, so that the thickness and bulk density of the rock wool board will not change.
     7. For cold preservation, a moisture-proof layer must be added. Under the condition of particularly low temperature, resin-free rock wool is used for heat insulation, and the moisture-proof layer must also be fireproof.
     8. Construction should be stopped in rainy day.
     Above is the introduction of precautions for using insulation rock wool board. Everyone should pay attention to these issues when using the insulation rock wool board, so as to prolong the service life of the thermal insulation rock wool board and use it more efficiently.
