| Model |
HT-2530 |
| Spray test method |
The spray gun used shall be equipped with a nozzle 1.3 mm in diameter allowing a liquid flow rate of 0.24 ± 0.02 liter / minute at an operating pressure of 6.0 bars ~ 6.5 bars. The jet shall be sprayed the mud & water almost perpendicular to the surface to be tested at a distance of 380 mm ± 10mm from the samples and the area impacted on the surface shall be 170 ± 50 mm |
Test mixture ( mud and sands)：
Contents of test
mixture are as follows |
Sands for test ( *PS：supplied by custome r)－ silica sands at a hardness of 7 in Mohs scale, a grain size in between 0 and 0.2mm in normal distribution and an angular coefficient ranging from 1.8 to 2.0.
The hardness shall not exceed 205 g / m3 when 25 g of sand contained in a liter of mixture. |
