- Concrete Knowledge 100 Questions (8)43. What is the impermeability of concrete?A: It refers to the concrete's resistance to pressure water infiltration. Both basement and reservoir are required to have good impermeability.44, impervious concrete commonly used impervious grade has a few?A: There are four commonly used impermeability gr
- AEO9 application field1. It is the ideal raw material for liquid detergent. Fatty alcohol polyoxyethylene ether is widely used to produce sodium fatty alcohol polyoxyethylene ether sulfate (AES). The physical properties of fatty alcohol polyoxyethylene ether make it not conducive to the preparation of laundry detergent,
- PEG Performance and Application1, polyethylene glycol series products can be used for pharmaceutical. Polyethylene glycol with low relative molecular weight can be used as solvent, cosolvent, o/w emulsifier and stabilizer for making cement suspensions, emulsions, injections, etc., as well as water-soluble ointment substrate and s
- What are the use ways of emulsifier AEO-9?Emulsifier AEO-9 is an admixture of natural fatty alcohol and ethylene oxide, which can be dissolved in water, ethanol, ethylene glycol and other substances. Emulsifier AEO-9 is a non-ionic surfactant, which is mainly used in emulsion, cream and shampoo cosmetics. Has very good water solubility, can
- The difference between dispersants and surfactantsThe main difference between dispersants and surfactants is that dispersants improve particle separation in suspension, while surfactants are substances that reduce surface tension between two phases of a substance.Dispersant is a form of surfactant. But all surfactants are not dispersants. In additi
- Cause of corrosion of metal by cutting fluidsCauses of cutting fluid corrosion of metal:1. Cause of corrosion1) The proportion of concentrate in cutting fluid is low.2) The pH value of cutting fluid is too high or too low. For example, when PH > 9.2, aluminum is corroded. Therefore, the appropriate pH value should be selected according to the
- Aluminum alloy special cutting fluid and ordinary cutting fluid differenceCompared with most steel and cast iron materials, aluminum alloy has many obvious characteristics in physical function. Pure aluminum has low strength, low hardness and large plasticity, which is suitable for plastic forming processing, but the deformation strengthening tendency is large when cuttin
- What are the differences between cutting fluid and cutting oil?Cutting fluid and cutting oil are collectively referred to as metal working fluid. Although they have 4 basic elements, but they are different in some aspects, today Xiaobian for you to sort out and edit the difference between the two to share with you:1, the difference of componentsCutting fluid an
- What are the differences between cutting fluid and grinding fluid?For the same kind of material, generally speaking, two kinds of finishing fluid can be universal, but grinding production processing than cutting production processing is easier to generate heat, so grinding on the cooling fluid demand is higher, with fully synthetic water-based cutting fluid can re
- Cutting fluid that can improve cutting conditionsCutting fluid, often referred to as coolant or lubricant, can be used to improve cutting conditions and extend tool life. Cutting fluid can be either liquid or gaseous. At the same time, cutting fluid can also be used for coolant and lubrication, such as fat oil. So, why more and more factories bega
