Initial Dry Cracking Resistance Test Device

The initial dry crack resistance test machine is a test equipment developed according to the technical conditions specified in the national standard GB9779-2005 "Multilayer Architectural Coatings".

Main technical indicators and working conditions:
a, wind speed control is: 3 ± 0.3M / S
b, working voltage: 200 ~ 240V 50HZ
c, laboratory temperature: 23 ± 2 ° C, relative humidity is 50% ± 5%
Equipment size: 1.2m*0.3m*0.3m

Scope of application: The CGK-2 initial dry crack resistance tester designed and manufactured according to the national standard GB9779-2005 "Multilayer Architectural Coatings" is suitable for the initial dry crack resistance of architectural coatings and indoor and outdoor construction putties under the specified wind speed conditions. test.

First, product features
The CGK-2 initial dry crack tester has a test plate parallel to the air flow direction in the wind tunnel. After the axial flow fan is started, the wind speed is adjusted to 3±0.3 m/s with the air volume control device. Place the painted test plate on the test rack in the wind tunnel. The drying control time is adjusted according to the product requirements. After the time is up, it will automatically stop, and the surface of the test board will have cracks.
