Problems solved by technology

Although the prior art CN103805808A discloses a copper-based catalyst alloy for scale inhibition, its production will cause certain pollution because it contains toxic trace metal elements lead and antimony, and its safety performance is not good. There is still room for improvement in anti-scaling and descaling, and there is still a need for safer, more stable and more effective anti-scaling and descaling materials

Embodiment 1

[0017]The full intelligent anti-scaling and descaling alloy of the present invention, the mass percent of each component is: Cu: 55%, Ni: 15%, Zn: 10%, Sn: 8%, Ag: 4%, Fe: 3%, Nb: 2%, Mn: 2.5%, V: 0.45%, C: 0.05%, each component is synthesized into a columnar crystal alloy oriented along the S110 crystal axis.

[0018] The preparation method of the all-intelligent anti-scaling and descaling alloy is as follows: prepare raw materials according to the mass percentage of each component mentioned above, and the raw materials are lumps with a purity of more than 99.9%, and their volume is less than or equal to 2cm 3 ; Spread 3cm thick charcoal in the crucible of the heating furnace, evenly spread half of the Cu material on the charcoal by weight, then evenly spread all the Ni blocks on the Cu material, and then spread 3cm thick charcoal, and start the furnace Raise the temperature to 1380°C. After all the metals are melted, add all the Fe, V, Nb, and C blocks, stir until the metals...

Embodiment 2

[0020] The difference from the previous examples is that the mass percentages of the components in this example are: Cu: 45%, Ni: 18%, Zn: 15%, Sn: 10%, Ag: 4%, Fe: 2.5%, Nb: 3.5%, Mn: 1.5%, V: 0.48%, C: 0.02%, each component is compounded into a columnar crystal alloy which grows oriented along the S110 crystal axis.

[0021] The preparation method of this example is consistent with that described in Example 1.

Embodiment 3

[0023] The difference from the previous examples is that the mass percentages of the components in this example are: Cu: 57%, Ni: 13%, Zn: 8%, Sn: 7%, Ag: 6%, Fe: 5%, Nb: 1%, Mn: 2.5%, V: 0.45%, C: 0.05%, each component is synthesized into a columnar crystal alloy oriented along the S110 crystal axis.

[0024] The preparation method of this example is consistent with that described in Example 1.

Abstract

The invention discloses a fully intelligent anti-scaling and descaling alloy, which comprises the following components by weight percentage: Cu: 40%-70%, Ni: 5%-20%, Zn: 8%-35%, Sn: 5% ‑30%, Ag: 0.5%‑20%, Fe: 0.1%‑8%, Nb: 0.01%‑3%, Mn: 0.05%‑5%, V: 0.01%‑2%, C: 0.01%‑0.5 %, the components are smelted at high temperature to form a columnar crystal alloy that grows oriented along the S110 crystal axis. The activation current of the invention is about 80 μA, and the stabilization time is about 150 minutes, which not only fully meets the engineering application requirements of scale inhibitors, but also increases the activation current by about 60% compared with the existing copper-based catalyst products, and the composition is more reasonable and safe, and the processing cost is also lower. Low.

Description

technical field [0001] The invention relates to an alloy material, in particular to a fully intelligent anti-scaling and descaling alloy and a preparation method thereof. Background technique [0002] The problem of fluid fouling exists widely in systems involving fluid transmission and circulation in heat exchangers, boilers and other industrial and civil fields, and even in the field of military aircraft carriers. In most cases, the fluid in the industrial pipeline system is in the state of simple substance or mixed solution, among which many factors such as solution composition, total salinity, total ion concentration, temperature, pressure, gas partial pressure, PH value, flow rate and so on affect the The solubility of the solute. Once the dissolution conditions of the solution system change, the solute solubility will also change accordingly. When the solubility decreases, so that the solute content is in a supersaturated state, crystals will be precipitated. Scalin...
