I will show you an easy way to galvanize using only the tools you have at home. Click here for the plan of the jig used in the video. jsk-koubou.stores.jp/
Just to be on the safe side always add the corrosive liquid to water, never add water to acids or alkali corrosive substance, depending on the concentration of the corrosive substance the water may boil off which can cause it to splash resulting in injury. I know this is a fairly low concentration of hydrochloric acid but better to be safe than sorry.
That was toilet cleaner which is already well diluted. No danger here. When working with pure or high concentration acid, the safety measure you mentioned, applies. Then, even glass rods are used to slowly and smoothly drip acid into water.
You have become my favorite craftsman to watch. Your technique is precise. You are imaginative and understand how to use power and hand tools. Its a pleasure to watch a gifted craftsman such as yourself. It seems there is very little you are not capable of building from materials common to wood workers and metal workers. Thank you for posting these videos. I do enjoy them and look forward to your next posting.
Buen trabajo de alquimia maestro y un gran resultado final, gracias por compartir sus conocimientos y experiencias, un saludo cordial y por supuesto un merecido like desde Narón (Galicia)👍🤓😜
When plating wouldn't it be better to rotate the part with some rotary device or cut the positive zinc electrode in 2 and have plates on either side of the part ?
Cool setup with commonly available items. I'd rather not brush and sand the coating though. Just to prevent damages in the thin surface coating leading to rust again.
I also did not understand why he chopped up a battery to get Zinc. Maybe he just had an old battery laying around and decided to repurpose it? Love to know if there is some reason for salvaging the zinc from the battery, or maybe that was the whole point of the video.
They are only zinc plated using the same technique he demonstrated. Considering the maximum thickness of electro-galvinisation is 1/40 of a millimetre, there won't be very much zinc to work with. You might be able to use things that have been hot dipped in zinc, (galvanised) but the best result will come from using unadulterated zinc. Zinc anodes used in the marine industry are expensive, costing anywhere from $50-80 per kg (AUD). So batteries will be the most cost-effective source for this use.
@@Mad4400 "costing anywhere from $50-80 per kg" at 7.133 grams/cm^3, 1kg of zinc has a volume of 140cm^3. If galvanizing a thickness of 0.05mm (=0.005cm), that kg of zinc is enough for a surface of 2.8sqm. At a price of 17 of average-Downunder-coffees in 2023 (AUD4.60).
I love the fact you took the maths to the next level and included a tangible cost item, but how does that figure compare to the zinc harvested from a D cell battery with a cost of $3.90 (AUD)? @@col0342
With 9.5% acid it doesn't matter. But showing it this way may make people believe it's ok doing this, and it's NOT! Always pour the acid into the water, not the water into the acid, that's secondary school science wisdom! Adding water to acid will cause a very violent reaction if the acid is more concentrated! Also, why dismantle a battery when you can get zinc plate at every hardware store?
EDIT: SORRY BUT I COMPLETELY SKIPPED THE FIRST SENTENCE OF YOUR COMMENT (I'll leave the original comment for anyone who will read the thread in the future) As you have seen, nothing happened, in the video there are no tricks, the saying not to give the acid a drink is valid for concentrated acids, here it is already at 10% and nothing happened, which is very different if for example you found himself having to dilute anhydrous sulfuric acid, in which case it would be truly dangerous to put water into the acid, even very slowly
@@zolatanaffa87 did you read what I wrote? I know that it's not a problem with so weak acid. But if people don't know, they'll also do it with stronger acid. It's irresponsible to show it like this, either that, or plainly ignorant. The problem with these RU-vid instructions is, that the creators never have to take any responsibilities for what they show. That said, I think most of his instructions are great, albeit sometimes over the top. But this one is right out dangerous by showing a wrong technique for diluting acid!
@@romedbucher2854 You are absolutely right as you will read in my edited comment. I hadn't come to think about the risk hidden in the video and I only commented on the part of what you wrote (skipping the first sentence, by mistake) I agree on the issue of giving all possible safety instructions in the videos to avoid unnecessary risks for users
Well, it is school fifth grade chemistry, so everybody should know it, therefore showing it this way would be OK, and shouldn't make people do wrong things. And the illiterate morons who passed through school like the goose through the pond, and don't know anything, should stay away from this kind of stuff.
I dunno that i'd do galvanization at home, nickel plating is much safer and lasts just as good if you do it right (thin layers, with cleaning in between). I've nickel plated nuts and bolts that have been reinstalled several times and the coat survives the mechanical action with no issues.
You can buy zinc metal sheets. Maybe using the old battery could be a kind of recycling but what you’re gonna do with the hazardous materials taken from the inside? Don’t tell me you throw them into trash?
Let me tell you why. First, concentrated acids cause violent reactions. This is elementary school knowledge. This is just an acidic detergent. And because you'll get more comments if you use batteries. In many ways. Of course, when I usually plate, I don't use batteries. This is a youtube show.
diluted hydrochloric acid = common household toilet cleaner or kitchen cleaner since its diluted its mild for cleaning use.....do not use 'hardware' hcl acid its more potent...as in melt skin.
many many mistake in this video. first, this is'nt galvanization, this is zinc electroplating. galvanization is imersion of steel part in hot fusion zinc bath. the zinc is alloying deeply with the steel and it's far superior than zinc electroplating and it didn't need passivation. secondary, your electroplating solution is very bad ! zinc ion salt is not concentrated enough, and you didn't use a conductive salt, (preferary an compound wich chelate with the metal ion you want plating)... this trouble result in very long plating time, bad throwing power that covering more high zone rather less low zones on the part. and burned deposit by using a too high curent density because of the bad solution conductivity. and using juste one anode doesn't help ! don't forget to use a surfactant too. The use of High curent density and not stirring the solution cause a lot of pitting by hydrogen embrittlement. idealy you should not see hydrogen bubbles while plating. heating the solution can help. and last thing, zinc electroplating must be passivate with divalent (called blue passivate) on trivalent chromium solution (called yellow pasivate, or bichromated)... instead the zinc plating won't last long and it will oxidate quickly. edit: after that, when the solution is well made, for a good deposits, you need to make square test pieces in copper, and test with different amperages to determinate the ideal Ampere/Cm2 and calculate with the plating part surface. exemple. ideal current density for this solution is 0,5A/Cm2. for a part with a surface of 10cm2 you need to apply 5A. etc... an other thing, use pure chemical and distilled water for electroplating. if you need HCL, don't use hcl based detergent, just buy HCl ! Don"t forget to degrease very well your part with NaOH solution and electrocleaning, followed by acid pickling before plating the part. and never toutch it with bare hand.
This is indeed galvanizing. Hot dipping is just one method of doing so. And hot dipping is definitely not alloying, as zinc melts almost 2000K before steel.
you didn't watch the video? it clearly showed he harvested the zinc casing/plate from the battery....manganese battery is the same as carbon zinc battery the most common battery anywhere in the world because its cheaper than alkaline battery.
I do not get it. You destroy a battery and end up producing a lot of environmentally harmful waste just to get hold of zinc sheet metal worth 2 cents, which you can easily buy in any hardware store or on Amazon? Sick. For the time again we are shown such crap here, the content no longer has anything to do with the great projects from 2 or 3 years ago. Subscription is canceled.
Wow! Are you the planet savior, aren't you... You know smartboy, Jisaku and maaany other people don't live in your mighty Retardistan, to buy 2 cents zinc sheets. In other countries which don't steal others resources like you do, the prices are high and some stuff is scarce. So, properly dismantle and dispose of a spent battery, to salvage some zinc sheet is quite useful and is for free. And as Retardistanis are among, the pollution "champions" of the world, your upset kiddo who takes his toys and goes home to mommy, attitude is just hypocrisy.
Those things were already manufactured before he repurposed them. Where does that hydrochloric acid end up with regular use as a drain cleaner? What happens to batteries once they have exhausted their charge? 2 cents would get you approximately 0.007 grams of zinc based on the typical price for zinc on Amazon. Your reaction is childish and a reflection of your intelligence.
