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

- In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.
- Q: How to go to the base of the teapot

- Q: A bit tall please help me one!
- As a result of the community on the misuse of waste batteries, such as: a button battery can pollute 600,000 cubic meters of water, a 5-cell can make a square meter of land is not grass, resulting in some public opinion bias, so that our waste disposable battery recycling And chaos dealing with the work, resulting in some unnecessary waste and mistakes.
- Q: That day, I put the alum in the water, and then I smell the gas, I would like to know the alkali is not harmful to people, right?
- The shortcomings of alkali is the food in the vitamin B1, B2 and vitamin C has a strong destructive effect, and will affect the body of certain minerals absorption and utilization, and therefore can not be abused.
- Q: What is the role of alkali in the surface
- Related to the crowd: the general population can edible production guidance: 1. Alcohol can remove the salad in the oil, the method is to wait until with the aroma of salad oil heated to hot, put a certain amount of soda ash, slowly with chopsticks Even can be; 2. Alcohol can remove the dough's sour taste, and can make the bread bulky white, but can not add too much, otherwise the bread will become yellow or crack, the taste will become bitter. Heat, taste bitter; with dehumidification, the food stagnation, detoxification of the role of acid. Note: 1. Do not put the food in the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated washing Several times can be; 2. Alkali is inorganic, itself does not have any nutrients, but the role of food cooking can not be underestimated, alkali solution of the electrolyte is the electrolyte, so that food raw materials (such as squid) in the protein molecules in water Ability to enhance the speed of raw materials to speed up, but should pay attention to master the amount of alkali, methods and time to prevent food raw material was too thoroughly, too bad or even deterioration.
- Q: The commonality of the base
- Alkaline solution can react with acid and alkali indicator
- 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.)
- Q: And how to do the big face ah?
- Pour the white vinegar, acid-base balance
- Q: What is the alkaline powder? Baking soda? Sodium carbonate or something else?
- Alkaline powder is used to do the soda with bread, and the same function with the soda powder.
