Description
Technical field
The present invention relates to a kind of environment-friendly materials, more particularly, to a kind of boiler heat supply network antisludging agent and preparation method thereof.
Background technology
Antisludging agent（scale inhibitor）：Be have can slightly solubility inorganic salt in disperse water, inhibit or interfere with indissoluble
The precipitation in metal surface for the property inorganic salt, fouling function, and maintain hardware to have a class medicament of good heat-transfer effect.
For from the mechanism of action, the effect of antisludging agent can be divided into sequestration, dispersion and distortion of lattice three part.And in experiment
In the qualification test of room, peptizaiton is the remedial measure of sequestration effect, and distortion of lattice effect is the remedial measure of peptizaiton.
Corrosion can cause huge economic loss.For hot-water boiler, corrosion removes and leads to reduce the life-span, increases considerably
Outside maintenance and overhaul cost, due also to corrosion leakage is frequently experienced in the winter heating period of severe cold, can be straight for thermal break
Connect the orthobiosiss having influence on resident.In order to change this present situation, research and development hot-water boiler anti-corrosion, scale-inhibiting technology is imperative.
Heat supply network scale inhibitor special is mainly made up of dispersant with high efficiency, phenolic hydroxyl group, sulfonic acid group etc., to the Calcium Carbonate in water,
Calcium sulfate etc. becomes the dirty factor to have distortion of lattice effect, makes dirt be difficult to be firmly adsorbed on wall, is loosely dispersed in water,
Show excellent scale effect.
With the quickening of China's urbanization and process of industrialization, the Industrial Boiler closely related with productive life and water bath
Stove heating system scale also rapid growth.The reasons such as the restriction due to boiler water technology level, Industrial Boiler generally existing
Corrosion and scaling problem, leads to boiler life to shorten, and safeguards and operating cost rises.
The common practice of China's industrial steam boiler water process is to pay attention to, outside pot, despising in pot.To small-capacity low-pressure boiler,
Commonly used tenderizer anti-corrosion, scale-inhibiting.To Large Copacity low-pressure boiler, commonly used tenderizer scale inhibition, anti-corrosion using oxygen-eliminating device method.
To medium-pressure boiler, commonly used tenderizer or deionization method antiscale, anti-corrosion using oxygen-eliminating device method.To high-pressure boiler, commonly used
Deionization method antiscale, anti-corrosion using oxygen-eliminating device method.However, developed country attaches great importance to processing in pot.To small-capacity low-pressure pot
Stove, commonly used antiseptic corrosion inhibitor method anti-corrosion, scale-inhibiting.To Large Copacity low-pressure boiler, commonly used softening-oxygen-eliminating device-anti-corrosion, scale-inhibiting
Agent method anti-corrosion, scale-inhibiting.To medium-pressure boiler, commonly used softening or deionization-oxygen-eliminating device-antiseptic corrosion inhibitor method anti-corrosion, scale-inhibiting.To height
Pressure boiler, commonly used deionization-oxygen-eliminating device-antiseptic corrosion inhibitor method anti-corrosion, scale-inhibiting.That is, it is equal to basic, normal, high pressure boiler
Employ antiseptic corrosion inhibitor.Certainly, the antiseptic corrosion inhibitor being adopted is not quite similar, and every kind of antiseptic corrosion inhibitor has its applicable model
Enclose.
The combination product that boiler heat supply network antisludging agent is made up of high polymers such as organic phospho acid and polycarboxylic acids, has very high delaying
Erosion and scale-inhibiting properties, its temperature tolerance is especially good, can be effectively applied to water process in the stove of low-pressure boiler.Boiler include hot-water heating,
Steam, locomotive boiler etc..Boiler special corrosion and scale inhibitor can also be used for the slow of the systems such as desalinization, distillation and radiator
Erosion antiscale.
Heat supply network scale inhibitor special is mainly made up of dispersant with high efficiency, phenolic hydroxyl group, sulfonic acid group etc., to the Calcium Carbonate in water,
Calcium sulfate etc. becomes the dirty factor to have distortion of lattice effect, makes dirt be difficult to be firmly adsorbed on wall, is loosely dispersed in water,
Show excellent scale effect.The features such as this product has that high temperature resistant, scale inhibition performance is high, is not easily decomposed, has inhibition, stripping concurrently simultaneously
Always dirty, anti-dehydration etc. acts on.It does not contain the carcinogen such as sodium nitrite, is all-organic formula, biological degradability is good, for green ring
Guarantor's type heating water special corrosion and scale inhibitor.
Heat supply network scale inhibitor special directly can make heating water with tap water, need not soften desalination, can greatly reduce heating
This, be that enterprise creates good economic and social benefit.
