¿que quimico es el recubrimiento rojo oscuro por dentro del embudo del crt?

that chemical is the dark red layer of the funnel is seen?

[0ldak]

@Giancarlo1991CCCCCCC hard to remember, but the name of this layer was "soft flash". By high resistance of layer voltage sloping down from anode - alu layer circuit to g4 gun contacts. This contains some ferric oxides and the layer must went through thermal furnace.

CRT's will always have a far superior picture (at least for a few more years anyway.) than LCD flat panels. Granted, this is due to the fact that CRT technology has been around for 50-60 years. BTW, does anyone know which brand name they're manufacturing here? Sometimes when the robot flips them over, it appears like they're making Sony's Flat Display Trinitrons.

CRT has been around since the 30s while in primitive forms it is even older when it came on the scene along with conventional valves/vacuum tubes. As for image standard LCD won't match period till pixel density improves but OLED will beat crt but refresh rate and the flexibility of resolutions might not be matched.

It's too bad so few manufacturers make CRT's anymore. If/when Funai decides to pull the plug, that'll probably be it. Then we'll have to settle for the lesser LCD's.

picture tubes cant keep up with todays high speed drivers. a lot of HD picture tube televisions have a harder time keeping up than the high speed transistor switching of TFT LCD and even greater speeds with Texas Instruments DLP technology projection systems. im not dogging on picture tubes, i have some old picture tubes for a 1970's tube based oscilloscope and.. well.. it works but not the best because of its age. picture tubes will always be Americas greatest invention from Thomas Edison.

gracias por escribir los componentes de los crt

saludos desde chile

[mamalon08]

physical area yeahh!!! i worked at lgpd gomez palacio plant 4 years for matching area and packing

nice video thanks

Very interesting stuff and nice documentary footage.

I've always thought that if the same technology and effort would be used on DISMANTLING old devices for recycling raw materials, then this world would be absolutely different. But we're as we're, and we just care about doing very well just half of the cycle, the one that ends in the dump yard. Additionally, energy cannot be recycled.

BTW, I still use a 10 year old korean 19" CRT monitor and I have no plans to change it in short term.

I worked in crt factory two years before. but i have forgotten a lot of things. if you want to dismantle a crt you should take care for environment

-gun - small steel and nickel parts (W,BaO,Al2O3,CaO,OsRu,BaO,SrO) + glas + imaco ring (Fe,Co,V,Cr) -base cap - small plastic part width silicon under base cap -coil copper, plastic, neck clamping, silicon for fixating -neck chromoxid layer (green one, not all types) -cone - coco layer (carbon), anode printing (silicone), softflash layer (lead), getter (barium), ims and mask (metal parts, blackering layer FeO4, bishmut layer Bi2O3), + spoilers (magnetoplastic, glue)

[0ldak]

-screen - matrix (carbon), phospohors (Ag,Au,Fe,Co,Sm,Eu,Tb,Y,Zn,S,C­u,Ni,Ce), aluminium layer -rimband steel + glued tape (fiberglass) -glass material = cone (clear), screen(B2O3,Al2O3,NaO2,K2O,Li2­O,CaO,MgO,Pb0,BaO)-fritting paste (Pb)

Interesting information, thanks.

It looks like a recipe of a soup. We extract the materials from the earth, we mix them to make the soup, and then spread back to the earth, all in a one-way process. As far as I know, just the copper is recovered (using zero-technology methods) from coils and transformers.

Most of the smaller B/W CRTs are still being made by hand!

[0ldak]

i trust you, i seen obsolete FTM or MBS matching machines with handy tilting rotation etc. this machines is a far history only. some times ago i had seen some cheap model of 32"LCD TV for 500€! CRT is a surpassed technology

Great footage you have there mate, goodbye to the good old Cathode Ray Tubes...
