How to make alum water, a simple way to make alum fertilizer water

Painting is inseparable from glue alum water, its preparation method is simple, the key is that the proportion of glue, alum and water should be appropriate. You can use yellow gelatin, or you can use edible gum, which is small granular and light yellow (glue and alum chemical stores generally have **). The preparation method of colloidal water is as follows:

Two parts of glue and one part of alum, respectively, soak in boiling water, pour them together and add appropriate water. Note that the alum is ground into fine powder to dissolve, and the foaming glue is boiled in boiling water, not boiled in water, because the adhesion of the glue will be weakened if it exceeds 100 degrees.

Generally speaking, to draw a four-foot-three-open cooked rice paper painting, you can use two parts of glue and one part alum with half a cup of water on the top of your little finger. Specific experience can only be gained by the author through multiple experiences in practice.

<> alum fertilizer water production method is relatively simple, that is, ferrous sulfate, dried manure, cake fertilizer, and water according to 1:3:5:

100 scale to configure. After the ratio is completed, it will be placed in the light and exposed to the sun for a month. It is fermented and rotted to become a black-green liquid, that is, the production of alum fertilizer water has been completed.

1. First of all, you can configure alum fertilizer water, and the usable ratio is ferrous sulfate, dried manure, cake fertilizer, and water according to the stove 1:3:5:

100 to keep its pH in between. It is then left to ferment in the sun for a month, so that the alum fertilizer water production is complete.

2. Choose a suitable glass container, put broken bones, cake fat, chickens, ducks and fish, internal organs, and all kinds of moldy and deteriorated rice, noodles, beans, etc. into the container, seal it with plastic sheeting, and expose it to the sun for a month, and ferment and rot it to complete.

After fermentation and rotting, the alum fertilizer water looks like a black-green liquid. However, it is not possible to water flowers and plants directly, it is necessary to mix more than 95% water and dilute it more than 30-50 times. In this way, it can promote the full absorption and growth of flower plants.

Alum fertilizer water after the use of many benefits, because it is an organic fertilizer and ferrous sulfate acid organic fertilizer liquid, so it can effectively improve the pH value of the soil, improve the fertilizer efficiency of organic fertilizer, can supplement trace element iron, so that the plant growth is more verdant green, strong and lush.

The production method of alum fertilizer water is: 20 25 kg of water, 1 kg of cake fertilizer, 250 300 grams of ferrous sulfate are put into the tank together, cover the lid, and put it in the sun for one or two months, and after its fermentation and decay, take the clear liquid on the upper layer to dilute the water several times before use, or in the rotted fertilizer water, add 1 gram of ferrous sulfate per 500 grams of fertilizer water, and then add water to dilute it.

It works well to use this water to water flowers that prefer acidic soils, such as camellia, rhododendron, and smile. Because the alum fertilizer water prepared with the above materials makes the soil slightly acidic, the pH is. Regular application of alum fertilizer water can keep the potting soil acidic, and promote the growth of flowers that prefer acidic soil, and the leaf color is dark green and bright.

Alum fertilizer water, the favorite of sour flowers, is simple to make and can be completed in a few steps.

Use 2 3 kg of water, 250 grams of ferrous sulfate, 1 kg of fragrant hemp ginseng after high-temperature fermentation for 1 3 months, and then dilute it with its supernatant with water.

Alum fertilizer water, the favorite of sour flowers, is simple to make and can be completed in a few steps.

Summary. Hello dear, thank you for your patience Oh <>

I'm here to answer your questions! Alum in hydrophilic water is a precipitation due to the formation of calcium carbonate in water with hard water. If you want to remove alum from water, you can do the following:

1.Filtration: The alum precipitate can be filtered by filtering the water using a strainer or strainer.

However, filtered water may still contain certain minerals and trace elements. 2.Boiling:

When the water is boiled, the minerals settle on the bottom of the water. After boiling, the water can be allowed to cool and the sediment can be filtered out with a funnel or filter. 3.

Add vinegar: Add an appropriate amount of vinegar to the water, acetic acid can react with calcium carbonate to form calcium lactate, reducing the formation of alum. It should be noted that too much vinegar will increase the amount of sodium and aluminum in the water, so it should not be used in excess.

4. Add salt: Adding an appropriate amount of salt to the water can prevent the formation of alum. However, too much salt can also turn the water into hard water, so it should not be used in excess.

1.Filtration: The alum precipitate can be filtered by filtering the water using a strainer or strainer.

However, filtered water may still contain minerals and trace elements that are well informed. 2.Boiling:

When the water is boiled, the minerals settle on the bottom of the water. After boiling, the water can be allowed to cool and the sediment can be filtered out with a funnel or filter. 3.

Add vinegar: Add an appropriate amount of vinegar to the water, and the vinegar bush can react with calcium carbonate to form calcium lactate and reduce the formation of alum. It should be noted that too much vinegar will increase the amount of sodium and aluminum in the water, so it should not be used in excess.

4. Add salt: Adding an appropriate amount of salt to the water can prevent the formation of alum. However, too much salt can also turn the water into hard water, so it should not be used in excess.

We need to pay attention to the fact that it is normal for water to contain certain minerals and trace elements, and it will not endanger human health. If the scale of the trapped fruit is severe, you can use water treatment equipment to treat it, or you can choose to buy bottled water to drink. Kiss.

Alum (Na2SO4·10H2O) is a common inorganic compound, calcining alum is to carry out high-temperature pyrolysis reaction, the chemical equation of sodium hydroxide and sulfur dioxide is:

na2so4·10h2o → na2so4 + 10h2ona2so4 → na2o + so3

so3 + h2o → h2so4

The entire reaction process can be represented by the following chemical equation:

2Na2SO4·10H2O 2Na2SO4 + 10H2O + O2 Tong Debate.

where the gas generated is oxygen. This reaction process produces a large amount of heat and oxygen, which needs to be carried out on special laboratory equipment, and pay attention to the safety of the forest.
