Benefits of technology

This patented technology describes different types of scales used during industrial processes such as coolants or boilers. These sticks out onto surfaces causing problems like fouling and corrosions. To solve this problem, certain materials have been added into these waters to improve their performance over those without them. However, there may still occur issues where they could get stuck up when mixed together too much at one point along the way. By combining several polymers in specific ratios we found another solution called lithium diphenate (LiBP). LiBP improves its ability to stop calcium carbonates from forming deposits but does little harm if allowed inside. Additionally, some other ingredients also help keep the scale agent moving around smoothly through the system while keeping good hydration properties. Overall, our technical results include enhancing the efficiency and reliability of scale control systems throughout various industries including manufacturing processes.

Problems solved by technology

This patented technical problem addressed by this patents relates to developing an effective fluorophore chemistry system capable of dispersing insolvable metals like calcium carbonate (CaCO 3) without causing any issues during storage overtime.

Abstract

The invention discloses a fluorescently-labeled scale inhibitor. The scale inhibitor is prepared from materials in percentage by mass as follows: 0.3%-0.8% of N,N'-ethylenebis(stearamide), 0.5%-2% of N,N'-ethylenebis(stearamide), 0.2%-0.5% of oleic acid amide, 0.3%-0.7% of barium stearate, 0.2%-1.5% of calcium stearate, 0.15%-0.5% of zinc stearate, 0.2%-0.5% of polyethylene wax, 0.2%-0.4% of polyethylene glycol, 0.1%-0.4% of bidentate ethylenediaminetetraacetic acid, 0.4%-0.7% of glyceryl monostearate, 0.1%-0.25% of hydrolyzed polymaleic anhydride and the balance of water. The internal elements are relatively stable, the loss of efficacy caused by internal combination is not prone to occurring, and by the addition of hydrolyzed polymaleic anhydride, the chemical stability of the scale inhibitor is better, the scale inhibitor is easily dissolved in water, can play a role in scale inhibition all the time along with the circulation flow of water and is more convenient to use.
