Examples
Embodiment 1
[0105] Weigh 2g of ethylenediamine and add 98g of scale and corrosion inhibitor II to obtain the first mixture, and use Beijing tap water to make a solution with the content of the first mixture of 25mg / L as water replenishment for the moving model; trichloroisocyanuric acid with 85% available chlorine Use deionized water to make an oxidative fungicide mother liquor with 1mg / mL of available chlorine, and use a constant flow pump to continuously add it to the moving tower pool at a flow rate of 1mL / min; after reaching the concentration multiple on the third day, sample and analyze the residual chlorine every day. The test results are shown in Table 2.
Embodiment 2
[0107] Weigh 3g of ethanolamine and add 97g of scale and corrosion inhibitor II to obtain the first mixture, use Beijing tap water to make a solution with the content of the first mixture of 25mg / L, and then add 2.5mg / L NH 4 + As the water replenishment of the movable mold; the NaClO with 10% available chlorine is made into the oxidative fungicide mother liquor of available chlorine 1mg / mL with deionized water, and is continuously added in the movable mold tower pool with a constant flow pump at a flow rate of 1mL / min; the third After Tianda was concentrated multiple times, samples were taken and analyzed for residual chlorine every day. The test results are shown in Table 2.
Embodiment 3
[0109] Weigh 5g of triethylenetetramine and add 95g of scale and corrosion inhibitor II to obtain the first mixture, use Beijing tap water to make a solution with the content of the first mixture of 25mg / L, and then add 2.5mg / L NH 4 + As water replenishment for the moving mold; dichloroisocyanuric acid with 65% available chlorine is made into an oxidative fungicide mother liquor with 1mg / mL available chlorine with deionized water, and is continuously added to the moving mold tower pool with a constant flow pump at a flow rate of 1mL / min Middle; after reaching the concentration multiple on the third day, samples were taken and analyzed for residual chlorine every day, and the test results are shown in Table 2.
