Fire retardant coatings are special coatings that provide additional protection and delay the spread of fire in the event of a fire. The paint usually contains chemicals that prevent burning substances from burning in the event of a fire and stop the spread of fire to other objects. Fire-resistant coatings are usually applied to the surfaces of buildings, ships, aircrafts and other objects that need protection to improve their fire rating and safety.
Detection performance
| performance | Test items |
|---|---|
| fire performance | Flame delay time, amount of smoke produced after combustion, flame spread speed, etc. |
| Adhesion | The degree of bonding between the coating and the substrate |
| weather resistance | UV resistance, water resistance, corrosion resistance, etc. |
| film thickness | coating thickness |
| drying time | coating drying time |
| density | Coating density |
| Paint content | The content of solid components in the coating |
| other | Such as antibacterial properties, chemical corrosion resistance, etc. |
Detection method
The following are commonly used detection methods for fire retardant coatings:
Fire performance: use fire simulation device to test flame delay time, amount of smoke produced after combustion, flame spread speed and other indicators.
Adhesion: The degree of bonding between the coating and the substrate is tested by cross-hatch method, peeling method, tensile method and other methods.
Weather resistance: test the UV resistance, water resistance, corrosion resistance, etc. of the coating through artificial accelerated aging test or natural climate exposure.
Film Thickness: Measure the thickness of the coating using tools such as a dry Film Thickness Gauge.
Drying time: Use a device such as a drying time Tester to measure how long it takes for the coating to dry.
Density: Measure the density of the coating using an instrument such as a densitometer.
Coating content: test the content of solid components in the coating by weighing, ash method and other methods.
Others: According to specific requirements, corresponding testing methods can be used for testing, such as antibacterial performance testing, chemical corrosion resistance testing, etc.
NBCHAO reminds you: Different testing methods are suitable for different types of fire-resistant coatings and different testing indicators, so it is necessary to choose the appropriate testing method and equipment according to the specific situation before testing.
