Check Method：
1、GB 11893-89 Ammonium molybdate spectrophotometric method was used.
2、GB/T 15452-2009 The Test Of Calcium and magnesium ions of industrial cooling circulating water; EDTA Titrimetry was used.
3、GBT 16632-2008 Test for scale inhibition of water treatment agent , Calcium carbonate precipitation method was used.
Test Method
Test Hard Water: Take some underground hard water from Qingyuan City Of Guangdong Province, Here below are the key indexes of water quality:
| Customer Name | Name Of Product | Underground water of Qingyuan City | ||||
| Sampling spot | Test date | |||||
| Method And Criterion For Judging |
1、GB/T 15452-2009 The Testing Of Calcium and magnesium ions of industrial cooling circulating water; EDTA Titrimetry; 2、GB/T 11007-2008 Experimental method of conductivity meter; 3、GB/T 6920-1986 The Testing Of water pH value; 4、GB 6903-86 The Analysis method Of Boiler Water And Cooling Water; 5、GB/T 6682 The Analysis Of Experimental Water Specifications And Method; |

| Name Of Water Sampling | Total Alkalinity（mmol/L） | alcium Ion（mg/L） | Magnesian Ion（mg/L） | pH value pH/℃ | Electrical Conductivity（mS/cm） | Total dissolved solids（mg/L） |
| Cooling Circulating Water | 5.8 | 105.0 | 14.0 | 7.63 | 0.636 | 294 |
| Test Conclusion | Calcium hardness is 119 (calcium + Magnesium) which is high hard water, contains a large number of scale-forming factors , such as Sulfate ion and heavy metals etc.. | |||||
The Testing Results Of Local Hard Water (a great deal of scales produced)：
Testing System Of Connection Method:
( The Flow Rate Of Testing System is calibrated to 10~12L per minute, Sampling for test per 80L, treated 14 ton water sampling for continuous 14 days)
Test Result：
Scale Inhibition Rate (%)
According to the test data, the active ingredients dissolved out steadily in the test process, the Anti-Scale Rate is greater than 94% averagely, meet the anti scale requirements of MSAP in complex environments.
After taking MSAP material sample out from water for continuous 14 days, originally 20g MSAP left 12.33g after washed and stayed in the Vacuum oven for 3 hours under 105 degrees Celsius. The total consumption of MSAP in the test is 7.67g；
