Abstract
In the prodn. we use hydrochloric acid as main part coordinated with small amount of citric acid (1-3%) and phosphoric acid (5%), and to the mixed descaling acid, are added tin bichloride 1-3% and thiourea inhibitor 5%, ammonium fluoride assistant 5%, silicon oil defoaming agent 5%, and appropriate amount of sodium dodecyl benzene sulphonate to prepare the product. The descaling agent has no toxin, harm and irritating smell, is strong in descaling power, and can be used for washing and descaling household utensils such as kettle, water-heater,s teaming electric iron, etc. and other metallic and plastic utensils.
Description
The present invention relates to the matting field, be particularly for a kind of domestic agent for cleaning and scale-removing, be applicable to the cleaning and descaling of articles for use such as family's kettle, water-heater, shower, also can be used for automobile radiator descaling.
Scale remover is requisite a kind of Chemicals in industry and the national life, domestic scale remover mostly is the strong scale remover that equipment such as being fit to Industrial Boiler uses at present, as KH-206 type scale remover of once winning Hebei province's scientific-technical progress second prize etc., this scale remover since be adopted that formaldehyde, first are stupid, hazardous and noxious substances such as methyl alcohol or stupid amine are as inhibiter, smell is big during use, pungency is strong, brings certain inconvenience for applying of scale remover.
The objective of the invention is to disclose the nontoxic scale remover that a kind of manufacture technology is simple, the scale removal ability is strong, do not have irritating smell, to satisfy social every profession and trade, the needs of family's scale removal particularly.
Task of the present invention is to be main raw material with mineral acid, organic acid, is equipped with various auxiliary agents, inhibiter is realized.
Major ingredient at various incrustation scales generally mostly is carbonate and a spot of silicate, it is the acidic descaling agent of major ingredient that the present invention adopts with hydrochloric acid, it is based on hydrochloric acid, and phosphoric acid, citric acid are to add a spot of inhibiter, auxiliary agent, tensio-active agent and defoamer in the acidic descaling agent of assisting to form.Wherein used inhibiter is tindichloride and thiocarbamide, and used tensio-active agent is a Sodium dodecylbenzene sulfonate, and used auxiliary agent is an ammonium fluoride, and used defoamer is a silicone oil.
The scale remover that the present invention provides is actually a kind of scale removal acid and tindichloride, thiocarbamide inhibiter that is made of hydrochloric acid, phosphoric acid, citric acid, the chemical mixture that Sodium dodecylbenzene sulfonate, ammonium fluoride auxiliary agent etc. are formed, contact the back with incrustation scale and reach scale removal, rust cleaning purpose, and do not corrode vessel by chemical reaction.The adding of citric acid and phosphoric acid mainly plays buffering and passivation in the scale removal acid, make the chemical reaction of scale removal acid unlikely too strong, guarantee the safety and stability of scale removal, tindichloride and thiocarbamide inhibiter are mainly used in the corrosion that stops ferric iron (Fe), cupric oxidisability ion pair iron and steel devices such as (Cu) here, Sodium dodecylbenzene sulfonate is used to promote the carrying out of scale removal process as tensio-active agent, and ammonium fluoride will be used for removing to incrustation scale small amounts of silicate dirt as a kind of promotor allowing.
This scale remover also can eliminate rust in scale removal, and chemical equation is as follows respectively:
The scale removal reaction formula is:
Wherein, (1) formula and (2) formula are the reaction formula of removal carbonate scale,
(3) formula is for removing the reaction formula of silicate scale
The rust cleaning reaction formula is:
Inhibiter tindichloride (SnL
2) adding be intended to reduction or shielding ferric iron this oxidisability ion, reduce slackening its corrosive power, inhibiter thiocarbamide (2(NH
3)
2CS) adding is intended to reduction or this oxidisability ion of shielding cupric, reduces and weakens its corrosive power.When reality is prepared, look the difference that is cleaned the scale removal object, in scale remover, can add two kinds of inhibiter simultaneously, also can add a kind of inhibiter wherein.
Preparation technology of the present invention is as follows: at first with the dilution of the technical-grade hydrochloric acid of 90% concentration or (6-18) dilute hydrochloric acid of % concentration, add 5% phosphoric acid and 1% citric acid then at normal temperatures and pressures and make scale removal acid, the inhibiter that adds (1-5) % at last at normal temperatures and pressures, (1-3) the ammonium fluoride auxiliary agent of %, an amount of Sodium dodecylbenzene sulfonate and (1-3) defoamer of %, stirring to filter gets final product.
The scale remover that provides among the present invention, owing to adopted nontoxic tindichloride, thiocarbamide is made inhibiter, and pungency is little, and smell is little, has improved operation and environment for use, and manufacture technology is simple, and is safe and reliable.This scale remover is applicable to the removing based on the incrustation scale of carbonate and various urine dirt and iron rust, patina.Outstanding and be applicable to the processing of family to vessel incrustation scales such as copper, iron, aluminium, stainless steel, pottery, plastics, also can be used for the processing of radiator incrustation scale.
Specific embodiments of the invention are as follows:
