How to judge hydrophobicity of rock wool easily?
1. Site easy hydrophobic test
(1) Shoot water to the surface of rock wool with drop bottle in hand
(2) Observe whether water spots permeate into rock wool. If they do not permeate into rock wool but form drop on the surface, it can be seen that the hydrophobic effect is good; if water spots permeate into rock wool to leave a mark, it can be seen that the hydrophobic effect is worse.
2. Wrong easy hydrophobic test method
Splash water on the rock wool strongly, the water will enter into rock wool under the effect of impact force to leave a mark, but this cannot be seen that the hydrophobic effect of rock wool is poor.
Notes: Easy hydrophobic test is only a simple method to judge the hydrophobic performance of rock wool, which cannot be regarded as the accurate method to judge the hydrophobic performance of rock wool. All shall be subject to the laboratory test data.

1. 현장 간편 소수성 테스트
(1) 점적병을 쥐고 락울표면에 물을 뿌립니다.
(2) 물얼룩이 락울에 침투되였는지 관찰하고 락울표면에 물방울이 맺혔을 경우 소수성이 양호하다는 것을 표명하고 락울속에 들어가 흔적을 남겼을 경우 소수효과가 비교적 차한 것을 표명합니다.
2.틀린 간편 소수성 테스트 방법
물을 힘있게 락울에 부으면 물이 충격에 의해 락울속에 들어가 물의 흔적을 남기게 되는데 이는 락울의 소수효과가 나쁘다고 할 수 없습니다.
주의: 간편한 소수성 테스트는 락울 소수성능을 판단하는 간단한 방법이지 락울 소수성능을 판단하는 준확한 방법은 아니며 실험실 테스트 수치를 표준으로 해야 합니다.
