Description
Technical field
The present invention relates to a kind of matting material, especially relate to the special matting material of a kind of water-heater scale removal.
Background technology
The incrustation scale of water-heater inside is very complicated, conventionally incrustation scale is divided into four classes by its main chemical compositions: carbonate deposit, silicate scale, sulfate scale and mixing incrustation scale.In water, contain calcium, magnesium ion and carbonate, bicarbonate radical, sulfate radical etc.In the time that water reaches certain temperature, calcium, magnesium ion are wherein combined with acid group, generate calcium carbonate, magnesiumcarbonate, calcium sulfate etc. and separate out precipitation, thereby form incrustation scale.
Incrustation scale can have a strong impact on thermal conduction, and calcium carbonate in incrustation scale, magnesiumcarbonate a large amount of depositions in human body easily form calculus.With the serious water face-washing of incrustation scale, have a bath, can form calcium magnesium soap, stick on the face, on skin, make dirt be not easy to remove.So no matter from water heater arrangement aspect or life aspect, regularly scale removal is necessary.Scale removal product category is in the market various, mainly contains industrial scale remover, as the scale remover of boiler detergent, eliminating sludge in pipe agent and other heat-exchange equipments.Along with growth in the living standard, people are also more and more higher to the requirement of quality of life now, so the share of market of household descaling agent is also more and more higher, household descaling agent mainly contains deincrustant of water dispenser, water-heater scale remover etc.
Chinese invention patent application specification sheets CN1213649A discloses a kind of compound method of descaling agent for gas water heater, the chemical substance and the weight percent thereof that adopt are: incrustation scale solvating agent uses citric acid or the tartrate of 2-8%, permeate agent uses polyoxyethylenated alcohol sodium sulfate or the sodium lauryl sulphate of 0.4-1%, inhibiter uses the benzotriazole of 0.008-0.03%, sequestering agent uses the thiocarbamide of 0.3-0.8%, suspension agent uses carboxymethyl cellulose or the sodium polyacrylate of 0.2-1%, all the other content are water, above-mentioned various chemical substances stirring and dissolving in water.Although this scale remover formula is better to the effect of metal protection, actual in incrustation scale solvating agent content is lower, descale effect is poor.
Chinese invention patent application monologue story-telling with gestures CN1301809A discloses a kind of household descaling agent, mainly contains concentration and be 31% hydrochloric acid, gelatin, hexamethylenetetramine, oxalic dialdehyde, and water.This scale remover adopts hydrochloric acid that molten dirty ability is stronger as scale-dissolving agent, but hydrochloric acid acidity is stronger, poor to the protective capability of metal.
In addition; the sewage draining exit direction of hanging electric water heater down; Powdered or liquid scale remover is difficult to be added in water heater liner, so the patent of invention of scale remover not only needs to consider descale effect and the protection to water heater liner, more needs to consider to use feasibility and the accessibility of operation.
