Description
calcium hydroxide is a kind of grey powder. It consists of calcium oxides, silicon dioxide, ferric oxide and little other ingredients. When mixed with appropriate water and poured into the pre-drilled holes, it will start to expand after half an hour, the expanisve power is increasing as time goes on. It can get 100-123 Mpa expansive power after some hours. Generally, the rock or concrete belongs brittle material, their tensile strength are far less than the compressive strength (for the tensile strength, rock is 1.96-30Mpa while concrete is 1.5-4.0 Mpa, they are equal to 1/10-1/20 of their compressive strength). Therefore, reasonable hole design can easily crack the rock and concrete or reinfored concrete by our BREAK-AG. As usal, it can crack the materials in around 2-24 hours. It is soundless, non-explosive, no noise, no vibration, no flying rock during the process of demolition.
Application
1. Mainly adjust acid waste water pH value, widely used for electroplate, chemical industry, circuit board, pickling, printing & dyeing and paper making, industries waste water treatment.
2. Used to remove phosphate,most of the heavy metal and ammonia nitrogen etc.
3. Used for tanning and mining industry etc.

Package, transportation and storage
Transportation: the product should be protected from damp, rainfall and package damage in transportation.
- Q: How does the edible base use?
- Avoid the food on the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated several times the raw material can be;
- 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: Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?
- In addition to medicinal function, alkaline powder also has a strong decontamination function. I brought a cup full of dirt, rinse with water, and then rubbed and rubbed by hand, but the dirt or tightly stick the cup. I add detergent, but also hard to rub, or stubborn dirt still still motionless. I sprinkled with alkaline powder, rubbing the side of the water gently rubbing the cup, those dirt seems to be afraid of alkaline powder like all fled, and soon the cup becomes smooth as new!
- 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: What is the name of the alkali?
- You say is probably the daily life of the [base] it?
- Q: How to go to the base of the teapot
- Vinegar, or toothpaste, you try
- Q: What is the use of alkali?
- Can be removed in the clothes when the clothes on the oil, you can neutralize the sour in the face, you can make the porridge easier to boil.
- Q: What is the role of alkali in the surface
- Nutritional analysis: 1. In the process of hair will have a microbial acid, dough after the initiation of acid, must be added to the alkali (carbonate) to acid off in order to produce a delicious pasta; And dark green vegetables due to the excessive spraying of pesticides and organic acids or sulfide, which can keep the original color of vegetables and pesticides to remove the pollution of vegetables; 3. Alkali has a strong role in degreasing, can Remove the oil on the dry goods on the raw material of excess oil; 4. Alcohol can release corn is not easy to release nicotinic acid, so that long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin; The disadvantage is that the food in the vitamin b1, b2 and vitamin c have a strong destructive effect, and will affect the body of certain minerals absorption and utilization, and therefore can not be abused.
- Q: How to see the whole bread of the alkali alkali small
- Shoot. If you hear the "air" sound, that the alkali put less; if issued a "bash, bang" sound, that the alkali put more.
- Q: What are the characteristics of the composition of the base?
- Can provide electronic pairs of substances. (Some salt solution of the pH value is greater than 7, but it is not a base, such as: soda ash (sodium carbonate) Na2CO3, baking soda (sodium bicarbonate) NaHCO3, etc.)
