Q:What is the alkaline powder? Baking soda? Sodium carbonate or something else?
Bicarbonate NaHCO3, is solid, powder is more common, commonly known as baking soda powder is weak alkaline substances, can inhibit the growth of fungi was originally used as a production of bread fermentation ... ...
Q:What is called alkali recovery
Alkali recovery treatment method is to solve the problem of black liquor is more effective way, through the black liquor extraction, evaporation, burning, causticization of the four main sections, black liquor can be SS, COD, BOD together and completely removed, and recyclable Alkali, resulting in secondary steam (energy). However, the alkali recovery system has high technical requirements and high investment in equipment. Since the small and medium sized paper mills are generally unable to bear the high cost of building the alkali recovery system, the alkali recovery system is only mainly used in large paper mills. In addition, the straw pulp produced white mud in the high silicon content, easy to burn back into lime, white mud may cause secondary pollution.
Q:How to go to the base of the teapot
Vinegar, or toothpaste, you try
Q:Is the base and baking soda the same substance?
Alkali is sodium carbonate, is granular, a bit like white sugar, baking soda is sodium bicarbonate, powder
Q:Alkali soda water
In 1772, Joseph Plistree published a book, "Combination of Water and Gas," describing the drop of sulfuric acid on chalk, releasing carbon dioxide and encouraging people to collect gas with a bowl full of water. In 1771, the Swedish chemist Luben Bergman independently invented a manufacturing process similar to that of Joseph Plistry's discovery of carbonated water. But less successful, he managed to produce natural bubbling spring water, then think that bubbling spring is good for health. Now, carbonated water is made by pressurized carbon dioxide through water. The pressure of the pressure is stronger than the standard atmospheric pressure, so that it increases the solubility, so that carbon dioxide into the. When the bottle is opened, the pressure is released, the gas forms a bubble out, thus forming a unique bubble. The best known for carbonated water is the advantage of removing stains, such as coffee stains in coffee cups, or silver stains. It is said that the wine stains can be mixed with salt, and then add a lot of carbonic acid to remove. Carbonated water is available at the grocery store and is also very simple. To the supermarket condiment counter bought to eat soda powder. Then prepare a bottle of mineral water. Will be a drink of water cups, put a spoonful of soda powder, how much soda powder can be based on personal taste to set. If put more, too salty, some people can not stand, put less. And then filled with mineral water, pay attention to the water must be cool. Now the living standard is good, every day big fish and meat eat, the body eat into acidic, drink soda can be neutralized in the body acid and alkali balance, good for health. Drink once or twice a week, stick to it, the body will feel particularly cool.
Q:I have been very confused, baking soda and edible alkali surface is the same thing?
Alkaline foods such as kelp, white radish, tofu, red beans, soybeans, apples, onions, kale, tomatoes, spinach and bananas are all things that are not easy to cause appetite but are beneficial to the body. Acidic foods, such as grapes, strawberries, lemons, etc., which are drooling, and in fact these things are typical of alkaline foods.
Q:Why does not the base noodles rub?
May add too much water. Noodle black is caused by alkali, you can use the source of gluten instead of edible alkali.
Q:What to do with the wall
Room regardless of the new wall or the old wall, will be due to excessive moisture with alkalization problems, especially in the wet environment, is the root cause of the quality of paint. In the brush before painting a layer of water-based sealing primer can not only save the cost of decoration, from the long-term and decorative effect point of view, brushing primer more effective with less. This kind of primer excellent sealing so that it can effectively resist the penetration of alkaline substances in the wall to prevent the precipitation of water soluble salt, to prevent the wall back to the alkali. At the same time, good adhesion of the primer makes the wall more smooth, so that the finish is easier to brush, reducing the amount of topcoat. In this way, the wall to avoid the paint disease, but also conducive to a longer time to keep the brushing effect. Also note that the primer and topcoat is best to use the same brand or with the matching paint to prevent the primer and the paint between the surface of the chemical reaction. Please read carefully the type or model of the primer (or finish) indicated in the packaging instructions.
Q:How to see the whole bread of the alkali alkali small
Sniffing Such as the smell of the dough, indicating that the alkali is placed properly. (4) catch. Hand dough, such as dough sinking, inelastic, that the alkali put more; if not sticky, nor sink, and there is a certain flexibility, that alkali is just right. (5) taste. Will be rubbing the base of the dough to pull a little bit into the mouth taste, if the sour that alkali less; if the alkali astringent taste, that the alkali put more; if you feel sweet, that is, alkali is appropriate The
Q:How does the edible base use?
Alcohol is not a commonly used condiment, it is just a food loose agent and meat tenderener, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use can bring excellent food The color, smell, taste, shape, to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread and so on.
