AA/AM/4-MNDMAPN-AQ properties of polymers

6 different inhibitors into the relationship between the amount of preparation and scale rate of polymer AA/AM/4. MNDMAPN. AQ dilute solution (C = 5mg / L), maintaining its concentration constant, dropping to which different amounts of H2O2 solution, place - 4, hours after the determination of H2O2 in a polymer solution under the existence of the fluorescence intensity and draw the fluorescence intensity of a relationship between the oxidant concentration curve shown in Figure 4. The figure shows, the oxidant of the polymer \'C! l ■ _ one by one Mexican fence 8l-Lin - ■ ■ ● ■ ● tE Wang, ■ mouth ■ = jAA/AM/4-MNDMAPN-AQ the fluorescence intensity to a certain extent, with the oxidant concentration, fluorescence intensity decreased, but the concentration of oxidant to a certain extent, the fluorescence intensity became stable and not affected by oxidants. 6 conventional scale inhibitors on the AA/AM/4. MNDMAPN-AQ fluorescence intensity of the first copolymer were accurately weighed I. 000g of the conventional scale inhibitor 2. Phosphoric acid 1,2,4. Three carboxyl butane (2-di ・ methylatephospho-nobutane-I, 2,4. Tricarboxylicacidmethylester,[link widoczny dla zalogowanych], PBTCA), BU-hydroxy ethane. I, I. Diphosphonic acid (1-Hydroxyerhy.1idene.I, BU DiphosphonicAcid.HEDP), a hydroxypropyl acrylate copolymer Acrylic (AcrylicAcidHydroxypropylAcrylmeCopolymers, T-225), aminotrimethylene phosphate (Aminotrimethylenephosphonicacid, ATMP), are dubbed a .0 g / L solution, shake well. Then the preparation of the synthesized fluorescent polymer dilute solution, maintaining the same amount of polymer,[link widoczny dla zalogowanych], were added to different amounts of scale inhibitor, the fluorescence intensity was measured, and the mapping of fluorescence intensity. Inhibitor concentration curve shown in Figure 5. It can be seen from the figure used in conjunction with his agent will not make the AMAM fluorescent polymer itself a major change in fluorescence intensity. 7AA/AM/4-MNDMAPN-AQ copolymer scale inhibitors pass away on the current performance of the performance evaluation method of scale has its advantages and disadvantages, taking into account factors such as experimental conditions,[link widoczny dla zalogowanych], we use a static method in the petrochemical standard pharmaceutical 【assessment scale inhibition performance. And polymer AA/AM/4. MNDMAPN. AQ and PAA (polyacrylic acid), HEDP (hydroxy ethylidene diphosphonic acid), HPMA (HPMA) and PBTCA (2. Phosphoric acid .1. 2,4. Butane tricarboxylic acid) and resistance scale properties were compared. The results shown in Figure 6: Figure 6 shows the performance scale with the polymer dosage increases, when the drug dose I2mg / L or so, have a relatively good scale inhibition performance. Under the same experimental conditions, we will Polymers and HEDP, HPMA, and PAA, PBTCA compared. The results show that the performance and scale polymer HEDP, PBTCA, HPMA, PAA relatively poor, but the scale polymer scale is formed when the powder or flake debris, shake flask, formed part of the scale will not be adsorbed on the sidewall, but rather floating in the solution,[link widoczny dla zalogowanych], so in practice, the scale with this agent, the formation of some of the dirt can be carried away, and not adsorbed on the wall of heat exchanger . Thus this agent has a certain practicality. 8 Conclusions (1) polymer AA/AM/4. MNDMAPN. Fluorescence intensity and the concentration of AQ showed a good linear relationship: the fluorescence intensity in the neutral environment of relatively large; conventional water treatment chemicals to the polymer did not affect the fluorescence intensity: but the oxidant will AA/AM/4-MNDMAPN . AQ fluorescence intensity decreased slightly. (2) were assessed by static scale inhibition performance of agents, polymers AA/AM/4. MNDMAPN. AQ scale inhibition properties with the increase of dosage, when the drug dose of 12mg / L or so, have a relatively good scale inhibition performance, under the same experimental conditions, to it with HEDP, HPMA, PBTCA and PAA comparison, M / 4. MNDMAPN. AQ scale inhibition less than conventional scale inhibitor HEDP, PBTCA, HPMA,[link widoczny dla zalogowanych], and PAA, but the drug by the end of the scale Jing is very soft, may be the role of lattice distortion is better, has a certain practicality. 2005No. 329
