Jump to content. Low Flow in Pipes - posted in Ankur's blog. Posted 02 April - AM. Hi there, does anybody know the mixing time of caustic soda NaOH with water at 25C, total mass is Initially i have Define what you mean by "mixing time".
It makes a difference. If you have a sufficiently powerful stirring mechanism, why would there be a need to know the exact time? If you really needed to know in detail the mixing dynamics, typically that would be for research purposes that would be a problem best done in CFD like Fluent or Comsol.
Otherwise, there are good correlations you can easily search for to design a suitable stirrer, whether it is turbulent flow or laminar, the type of impeller and number of blades, baffle factors etc.
My advice, don't do unnecessary calculations for the sake of doing it. Temporal equations are always complicated PDE's. Ask yourself on the need to do it. I need to know cause my process should be continuous if it takes long period of time then mixer or storage tank should be installed. Posted 02 April - PM. Your problem is related with mass transfer, you can review the textbook "Principles of Mass Transfer and Separation Processes" by Dutta B.
The basic reference is the paper of Barker J. I hope help you. You need define various parameters then you have a integral for the time determination. Posted 09 April - AM. Around 80 C I think.

KaneHApr 5, Things like dilution rates, equipment, solution life, heating, disposal, materials suitable etc etc. Any advice to prevent me from burning a hole through my hands would be great TIA. Messages: 6, uk colchester Location: uk colchester. KaneH and Anguz like this. For something like an alloy wheel I would use maybe 4 of them and 40l of water. Warming the solution makes it work a lot more aggressively or quicker although aluminium reacts a lot quicker than steel anyway.
Warming it helps, I normally mix up a strong solution with soda and cold water then chuck a couple of kettles of boiling plus a few more from the hot tap. It gives off pretty nasty fumes when warm, especially if you dont mix it with cold water first. Mixing it directly with hot water will knock you out. If you have a large volume or a lot of bits to do an immersion heater element will heat it but get a thermostat or keep a close eye on it.
Mine is set to 60dC. Seems to work nicely but not tried any other temperature apart from room temp Stiring or agitation works well, make a bit of pipe with a load of holes and feed compressed air into it as the bubbles seem to give a better finish.
You might want to suspend the part off the bottom of the tank as you quickly get a layer of sediment and that does not seem to clean anything and on something like a wheel you will get a tide mark that you can not get rid off.
Breathing is the main thing, you need to do it outside. Gloves are a good idea but a supply of fresh running water is also a good idea. If it splashes on you or your cloths it will give a fairly nasty burn after a while. I have had a couple and I have skin like a rhino. It seems worse if it splashes clothing than on bare skin, probably because its held in contact for longer.
If it does splash on you a good wash off with running water is fine. Eye protection as well if it does get in your eyes get a hosepipe on them for at least 5mins then flush with saline to stop them drying out. Be aware that if it gets in both eyes you wont be able to find the hose! Using the stronger liquid solutions properly!
A few hours later you might be miles away from any water and if you do something that makes you sweat it reacts and starts to burn.
It's also easy to get the dust on you and then you try to pick something out of your eye a few hours later I normally have a tub big enough that I only need to fill it half full which stops a lot of splashing. When finished I just fill it completely with the hose and let it overflow for a while. As far as I know it's fine to go down the drain as its sold as drain cleaner anyway. Edit: the pots from homebase might be g or something. KaneH likes this. SeadogApr 5, Why don't fictional characters say "goodbye" when they hang up a phone?

Category : caustic sodaUncategorized. Tejaras Co. State-of-the-art manufacturing facilities of detergent chemicals and raw materials in top governmental plants, has made us able to supply highest quality detergent chemicals and raw materials at most competitive prices. Caustic soda sodium hydroxide is one of the most important raw materials in manufacture of detergent chemicals. It is used in saponification, the process that converts vegetable oils into soap.
Caustic soda is also used to produce anionic surfactants which are largely used in detergent chemicals and cleaning products. LABSAsulfonic acid also known as acid slurry is one of other major detergent chemicals we export. LABSA is the most common anionic surfactant for synthetic detergent powder. There are some important factors that detergent manufacturers prefer sulfonic acid to other anionic surfactants. We can point out good solubility in water, high detergency and foaming, and economical prices among those important factors.
Soda ash is used as the builder washing auxiliary in detergent industry. Its main application is to be used as a solvent which can remove a wide range of stains. Also, soda ash can be dissolved in water in order to create a pre-soaking solution for tough stains like coffee, tea, blood, grease, and oil.
SLESsodium lauryl ether sulfate, also known as Texapon is one of other major detergent chemicals we supply and export. SLES is widely used in liquid detergent such as shampoo, hand washing liquid, dishwashing detergent, and bubble bath liquid. Sodium hypochlorite is the most powerful home bleach. Using sodium hypochlorite aids detergent products in the removal of stains and soil.
Once sodium hypochlorite is used in the wash, it acts as a disinfectant on bacteria and viruses and generally whitens most natural-fiber fabrics like cotton.

We will get through this together. Updated: April 3, References. A clogged sink can be a major inconvenience, but before you call a plumber, consider unclogging your sink at home. Manual removal works well if you have large clumps of debris jamming up your pipes, but you can also create natural drain cleaners or use chemical cleaners to help rid your sink pipes of unwanted material. Here are the most common methods you should consider trying the next time your sink gets plugged.
To unclog a sink, try using a plunger to loosen the clog like you would a toilet. Make sure the sink has 3 to 4 inches, or about 7. Then, holding the plunger upright, plunge vigorously for 20 seconds or until you feel the pressure give way.
For really stubborn sinks, combine 1 part baking soda and 1 part vinegar in a glass and pour it down the drain, or use any commercial drain-unclogging product. Let the mixture sit in the drain for 20 minutes before flushing it out with boiling water.

It might be to earn extra income, or to save your earnings; or to get the quality you deserved. Whatever might be your reasons; I want to tell you that you are in the right place.
Making liquid soap is one thing, while making a quality liquid soap is another thing. Liquid soap is used for different purposes; from washing ditches to washing clothes and many more. You will remember that I promised to teach you my two best methods to making liquid soap. Though, there are so many methods for making liquid soap but this is my favorite.
Because, it is fast and the end product is usually very beautiful. Before I go into details. Let me quickly clear the air on some questions people have been asking me lately.
You will remember that there are almost eight chemicals used in making liquid soap. But the truth is that you do not have to use all the eight chemicals. Let me quickly run through them again. Take a break of 30 minutes for all the chemicals to dissolve. You can also stir anyone of them to aid its. Now you can start using your liquid soap right away. It might not look clean immediately after production; you might see some small small burbles in it but this make way after some hours like 24 hours.
Please, drop you comments bellow let me know if this method is clear or better still if you have any questions. Good afternoon sir…… Thanks for the good work u r doing here. Sir,if want to make 50liters of liquid soap,should i just double the measurement above or there is a measurement of chemicals for it.
Thank you for this post. My soap is not active using, turns to water within seconds.
