Description

The production method of iron pan cleaning sand of attapulgite

Technical field:

The present invention relates to clean-out system, be specifically related to a kind of production method of iron pan cleaning sand of attapulgite.

Background technology:

Along with the develop rapidly of modern industry, various cooker emerges in an endless stream, and we often use electric cooker, pressure kettle, and the pot of cooking has iron pan, aluminum pot, Stainless Steel Kettle and marmite etc.The characteristics such as dish delicious flavour that iron pan has is solid, durable, be heated evenly and fry, stew out, and use the iron pan cooking, the iron-holder in the dish is increased, replenish the human body ferro element, iron deficiency diseases such as anaemia there is certain benefit.Scientist once did toning and checked ratio, found life-time service iron pan person, and the chance of suffering from anaemia is than the people's much less with other pots, and inorganic iron is easier to be absorbed by the body than the organic iron in the food.

These cookers have brought new hidden danger also for people's health when bringing convenience to people, and along with the appearance of cookers such as aluminum pot, non-stick pan, pressure kettle, iron pan is more and more far away from us.

The minimizing that iron pan uses, more relevant with the cleaning difficulty of new iron pan, there are the impurity of leaving in one deck ferric oxide and the castingprocesses such as coating on the surface of new iron pan, before using new iron pan, need clean new iron pan, and the difficulty of cleaning is bigger, and using general washing composition is impossible new iron pan is cleaned up.

Chinese patent publication number CN1049033, open day is on February 6th, 1991, and name is called " detergent for new iron pot ", and it discloses " a kind of ammonium sulfate, bentonitic mixing Compositional type clean-out system of containing.Be applicable to the iron pan surface cleaning of diecasting, changed traditional purging method, the time and labour saving, effect is obvious.These product also can be used for cleaning with diecasting ferrous products surface ".

The foregoing invention weak point is, detergent for new iron pot " contains ammonium sulfate, bentonitic mixing Compositional type clean-out system ", " also can add a spot of quartz sand ", the ash quarrel on iron pan surface simply can only be removed, ferric oxide and cast paint layer can't be decomposed, be difficult to the surface of new iron pan is removed totally, can have influence on the normal use of iron pan.

Chinese patent publication number CN1051400, open day is on May 15th, 1991, name is called " deashing agent for new cooking-pan ", it discloses: " a kind of deashing agent for new cooking-pan; it is characterized in that containing non-toxic alkali carbonate 10-80% (weight), polysilicate 5-70% (weight), 10-40 carbon organic acid 5-60% (weight); 10-40 carbon organic acid salt 5-60% (weight), polymeric carbohydrate 5-20% ... ".

The foregoing invention weak point is that the main component of deashing agent for new cooking-pan is yellow soda ash and sodium polysilicate, the ash quarrel on iron pan surface simply can only be removed, and ferric oxide and cast paint layer can't be decomposed, and is difficult to remove the surface of new iron pan clean.

Summary of the invention:

The objective of the invention is to overcome weak point in the prior art, the production method of the iron pan cleaning sand of attapulgite of a kind of easy and simple to handle, the oxide compound that can remove the iron pan surface fast and cast paint layer is provided.

The production method of iron pan cleaning sand of attapulgite is divided into two stages: first stage is carried out acidification with dilute sulphuric acid to attapulgite clay earlier, Concavo-convex excellent stone clay after the acidify is pushed and roasting again, obtains flaky activated attapulgite; After second stage mix activated attapulgite, citric acid, sodium lauryl sulphate and potassium permanganate, pulverize and be irregular sand particle, be packaged as finished product.

Attapulgite clay is after acidifying and roasting, not only improved the activity of attapulgite clay, strengthen the absorption and the decoloration performance of attapulgite clay, and the attapulgite clay sand grains after pulverizing has in soft hard, tiny soft sand grains is accompanied by citric acid, sodium lauryl sulphate and potassium permanganate, fellowship carries out chemical reaction to the surface of new iron pan, promote impurity such as the oxide compound on new iron pan surface and coating constantly to decompose, the tiny soft sand grains of Attapulgite is with its absorption and break away from the upper layer of new iron pan, bigger slightly Attapulgite hard sand grain surface is sharp-pointed, and a large amount of micropores arranged, in the process of cleaning, pass through physical action, can increase the scouring dynamics to new iron pan surface, improve the speed of cleaning iron pan, iron pan cleaning sand of attapulgite can also be removed the iron rust peculiar smell of new iron pan.

The present invention is achieved by following technical proposals:

1, the production method of activated attapulgite is:

1. the preparation of dilute sulphuric acid comprises following component by weight percentage: the sulfuric acid 3～5% of concentration 98%, water 95～97%;

2. the batching of acidification comprises following component by weight percentage: attapulgite clay raw ore 55～65%, dilute sulphuric acid 35～45%;

3. extruding: with Concavo-convex excellent stone clay after the acidify, push by extrusion machine and to be flap, the thickness of flap≤3 millimeter;

4. roasting:, the flap of attapulgite clay is transported to and carries out roasting in the stoving oven, and roasting time is 1.5～3 hours, and maturing temperature is controlled at 320～450 ℃, and the attapulgite clay flap after the roasting is an activated attapulgite.

2, the production method of iron pan cleaning sand of attapulgite is:

1. iron pan cleaning sand of attapulgite comprises following component: activated attapulgite 65～90%, citric acid 5～30%, sodium lauryl sulphate 1～5% and potassium permanganate 0.01～0.5% by weight percentage;

2. after activated attapulgite, citric acid, sodium lauryl sulphate and potassium permanganate being mixed, be transported in the pulverizer, pulverize and be irregular sand particle, and sand grains is sieved, grid≤1.5 millimeter are packaged as finished product.

When cleaning new iron pan, earlier that iron pan surface water is moistening, use scrubbing cloth or steel wire lump, be dipped into an amount of iron pan cleaning sand of attapulgite, spread upon the surface of new iron pan, clean on the surface to new iron pan after 1～5 minute, impurity such as the oxide compound on new iron pan surface and cast paint, to constantly decompose and along with a large amount of foams breaks away from the upper layer of new iron pan, reaching the purpose of cleaning iron pan, the free from extraneous odour that becomes clear of the new iron pan surface clean after the cleaning.

Iron pan cleaning sand of attapulgite also is applicable to the oxide compound and the spot of cleaning other metallic surface.

Embodiment:
