Embodiment 1
[0050] Get the 1.0 generation EDA-PAMAM 20g that comparative example 2 prepares, add 12.5g solid content and be 40% polyepoxysodium sodium succinate (PESA), 12.5g solid content is 40% polyaspartic acid sodium (PASP) , 25g of IA-AMPS with a solid content of 40% and 30g of deionized water, stirred evenly to obtain 100g of a composite scale inhibitor with a solid content of 40%. In the prepared composite antiscalant, the content of 1.0 generation EDA-PAMAM is 20%, and the content of PESA is 5%. The content of PASP was 5%, and the content of IA-AMPS was 10%. The compound antiscalant prepared above was subjected to the performance test experiment of inhibiting silicon scale and calcium scale. The scale inhibition results are shown in Table 2.
Embodiment 2
[0052] Get the 1.0 generation EDA-PAMAM 15g that comparative example 2 prepares, add 12.5g solid content and be 40% polyepoxysodium sodium succinate (PESA), 12.5g solid content is 40% polyaspartic acid sodium (PASP) , 37.5g of IA-AMPS with a solid content of 40% and 22.5g of deionized water, stirred evenly to obtain 100g of a composite antiscalant with a solid content of 40%. In the prepared composite antiscalant, the content of 1.0 generation EDA-PAMAM is 15%, and the content of PESA is 5%. The content of PASP was 5%, and the content of IA-AMPS was 15%. The compound antiscalant prepared above was subjected to the performance test experiment of inhibiting silicon scale and calcium scale. The scale inhibition results are shown in Table 2.
Embodiment 3
