Guangzhou Steel tells you: fireproof coatings inspection process after construction

Fireproof coatings as a construction material in the construction is completed this process must be tested, then test for fireproof coatings how have requested it, following Guangzhou Steel come to find out.

1, fireproof coatings test should provide the following reports:

(1) fire-resistant fire retardant coating countries view the institution of the limits to view reports and view reports of physical and chemical properties, fire supervision department issued a production license and production of the factory's product certification;

(2) the construction site to view the document and quality management during the construction process submissions major questions;

(3) See shaded engineering inspection items inspection records;

(4) completion report after the completion of the single and self-test report;

(5) the amount of purchase orders fire retardant coating;

(6) Fire paint coating edge construction side view records.

Fireproof coatings should be included in the "construction of fire facilities View order", "construction project fire inspection norms" and other technical specification, all painted interior and exterior coating of steel structure fire test before the completion of construction, the agency must have a view of the steel body structure fire retardant coating to view compliance report. Fireproof coatings viewing and inspection is mainly based on: GB14907-2002 "steel structure fire general technical conditions", GB50205-2002 "steel works and construction quality inspection norms", CECS24 "fireproof coatings technical specifications." Guangzhou Steel steel structure fire fire resistance of measuring methods, should be based on the type of environment and concluded by the fire, such as: petrochemical enterprises to use fireproof coatings, its fire resistance test should be based on temperature curve hydrocarbon fire determined before more realistic.

After brushing fire retardant coating on steel, greatly improving the fire resistance of steel, but in fireproof coatings applications, there are coatings improper selection, poor construction management, completed inspection, viewing and many other non-standard questions , seriously affecting the quality fireproof coatings.
