By the Orange WTDS Label or World Tube Designation System, it was a Sony CRT. In 1995 I started working for Sony in San Diego. They were building the 17 inch Monitor Line when I started. At the time they were doing 32, 27, and 20 inch CRT's for TV's and Building 32 inch TV's in the Basement. I worked in the production of the 17 inch CRT's. That metal band is called a Heat Shrink Band. It is applied after tape is wound around the CRT. The tape is a Thermal Protection for the CRT, if the CRT does not have the tape the CRT will Implode in the next step. The Band is heated red hot with a RF Generator and pulled over the CRT then COLD Air is shot on the band so it shrinks. The band is tapered and it causes the center of the face of the CRT to Bulge out slightly. Even though the CRT has a Vacuum. This is a Safety so if the CRT is Broken the Stress on the Front Glass causes the glass to shatter inward rather than at the Customer. In my area of responsibility we did the Heat Shrink Band. During Shift we would cut one band per hour with a jig to measure the deflection of the screen when the band was cut and the band pressure was released. The Glue mentioned is called FRIT. It is a Ceramic Based GLUE. Cured in a 4 hour oven ride. The inside of the CRT Metal is called an Aperture Grill. The area where the Tech punched a hole to release the Vacuum is called a high Voltage Anode. And like pointed out the Silver is Aluminum with 3 colors of phosphorus. In Production and Storage the RED Phosphorus was under Video Surveillance 24/7 as it could be used as an ingredient in a Illegal Drug. In the 4 years I was in San Diego they added the 19 inch Monitor CRT Line. In 95 when I started while waiting for our equipment to be installed I shadowed a Tech / Mechanic in the 32 inch CRT Area for Training. After 4 years I transferred to the Bristol, PA Sony Service Center for 4 years closer to my home fixing PlayStation 2's and stuff. In this video it shows at the 10 min part of the video where the base cap is applied and liquid carbon is painted on the outside of the CRT by a Fanuc Robot. The end of my area was where the CRT was packed off in Foam on a pallet. th-cam.com/video/yNkIgVwr_nQ/w-d-xo.html
that is the most relevant comment on TH-cam ever!
thats actually quite interesting more so than the video in fact
those flat screen Sony CRTs are nice
THIS is What they are not telling you. Recycling leaded crt glass is almost impossible. Years ago, a company called closed loop recycling and refining abandoned over 300 million pounds of crt glass. This company took in millions of pounds of crt glass from other recycling companies, while promising a new way of recycling crt glass. Due to this being extremely difficult and expensive, the company went bankrupt, leaving 4 massive warehouses, and large outdoor stockpiles of crt glass abandoned, resulting in massive lawsuits and a 5 year long multi-million dollar cleanup. All this crt glass that was promised to be recycled, but ended up causing environmental damage, and ultimately buried in a landfill.
why not to use for concrete mix in building shelters ? would it provide the barrier for radiation ?
@@simonkh7278 Maybe, that’s a good idea, but there probably is such a small demand for something for something like that and it’s just not feasible.
@@BGTech1 The crt glass toxic levels have been studied and risks were lowered.
Some construction companies use it instead of sand, it makes concrete less water and temperature impacted
Those coils of wire on the crt neck is the deflection yoke - NOT a transformer.
The electronic recycling event in my neighborhood was much more simple. They had a trash truck painted with leaves and the color green. They put the tvs in and crushed em. Imploding multiple at a time!!! It was AWESOME!!! 😎. the green truck ment it was good for the environment.
thx. amazing and simple separation
2:10 - They implode in an instant. Ive had one go on me before and I didnt have time to blink before glass was hitting my goggles. Also, do you recycle the phosphor? I know it has rare earth oxides in it.
Lovely high voltage transistors on the circuit board... ;-)
Hi I have two crt tubes just the crt I scrapped the rest, is there a place I can call to ship it to u guys?
Very risky handling of the material, high probability of bodily injury, in addition the operator is not wearing any protective gear.
I have taken apart hundreds of these with zero protective gear.
Nice. DId the worker died by now due to lung issues?
At 6:01 when the guy vacuums a white substance off the screen, is that the phosphor? Do you guys do anything with that or do you just throw it out as waste?

Man... Look at that dell trinitron p1130... I would never let it end up in a landfill

non o avuto modo di vedere in quale modalità sono smaltiti i cannoni elettronici dei crt; i cui catodi, sono in parte ricoperti di elementi radioattivi; Ho visto che vi preoccupate di recuperare i metalli non pericolosi acciaio Rame e Piombo e altri; Asportate il fosforo degli schermi dal vetro; la decompressione dei tubi fatta sfondando il recipiente nel foro destinato al contatto dell'anodo alta tensione, mi sembra alquanto rischiosa il tubo potrebbe implodere causando danni a'operatore, che nell'operare non appare particolarmente protetto; in realtà per decomprimere i tubi bisognerebbe rompere il condotto sigillato a fuoco, presente nell'estremità dello zoccolo, tale tubo utilizzato per produrre il vuoto, sigillato a fuoco, è collegato a un tubicino calibrato, che se rotto, consente il riequilibrio delle pressioni ,. in tutta sicurezza! A mio avviso, bisognerebbe caricare i costruttori di questi componenti del riciclaggio di questi materiali! Loro certamente sanno cosa realmente contengono! è la solita storia idustriale: I guadagni agli industriali; i costi alla collettività: Altro che economia circolare!
the silvery wire on the tube is tin coated copper
Is there palladium in the tube. The tip?
Except its all going to be sent to a landfill instead of being recycled
I have no time

Crt work bader than big shit of lcd expansive and it will repaired after 3 years of used
Another CRT correctly processed, and one less of the bastards in the world. Dunno about the recycling factor. Germany would productively re-process the leaded glass close to closed loop standard. But in the USA they'll probably just pour it some furnace. The last bit, the " panel glass " is up to grade to qualify for recyclable glass cullet. O-I could make bottles from it. But what shall become of it is creative disposal, most likely road base.
100 millions lbs of crt glass from closed loop was taken to a landfill instead of proper recycling
@@BGTech1 Ah, so. They gotta get their act together, eh. Landfill, though, beats energy incineration. Mmm, I think..
There has to be a better way. This is way too labor intensive.
That's why no one takes crt tv's without a fee, or most any e waste for that matter... It's not easy to separate all the materials, and no one wants to but metal that is contaminated with plastic and junk. I was actually surprised how cleanly they were able to split that tube!
