    Unveiled In The History Of The Unknown Poison Watch

    Almost everyone who likes watches has a more or less understanding of luminous. However, luminous watches in history actually contain highly toxic, even if the amount is very small, plus the protection of the glass watch cover, but it will also cause harm to the human body, then, what is this mysterious luminous composition?

    The earliest pocket watches had no luminous configuration. The reason is of course that luminous powder was not yet popular. The true popularity of luminous light is closely related to the gradual popularization of military instruments in war. Early military instruments include military watches, because there is no night light, it is very difficult to watch time at night and in the dark; and it is very dangerous to turn on a flashlight or other light source, because it is possible to expose the position due to light exposure (such as a flashlight or a light) during the war. Is deadly.
    Panerai’s luminous watch was originally designed for Italian divers
    Around the 1910s, radium luminescent powder was introduced in watches. Twenty years have passed since the Curies discovered radium. In the past two decades, the extraction of radium has been converted from simple bitumen to electrolytic radium chloride production. The cost and scale have changed relatively, and they have become suitable for industrial applications. Radium is a radioactive element that can emit both alpha and gamma rays, so it can produce self-luminescence with a certain brightness after a certain synthesis, which is relatively suitable for making noctilucent materials for close observation. Therefore, the fluorescent coating made of zinc sulfide, radium bromide and neofluoride was mixed with glue and applied to military instruments and watches.
    Tritium radium is a standard radiation and highly toxic substance. Even if it is used in very small amounts, plus the protection of the glass cover, it will also cause harm to the human body. However, many of the noctilucents we see now in the 1940s and before are not left over from radium luminous powders. The main reason was that most of the watch cases were not waterproof at the time, and the intrusion of water and moisture caused chemical reactions to cause the radium luminous powder to age very quickly and even fall off quickly. Therefore, many of the old radium luminous materials that have been soaked over time have failed or even fallen off. Some second-hand watches are refurbished with a tan blend of new luminescence, but that’s something that is already in both worlds. The famous brand PANERAI named a series of Radiomir luminous products they used in the past, indicating that Ramen luminous light once affected a considerable area.
    2, 氚 noctilucent, the solution to illuminate the Bohr noctilucent watch for half a century is to use a self-luminous micro steam lamp glass tube with a luminous coating on the inner wall, and radon is enclosed in it. When the electrons released by plutonium hit the inner wall of the glass tube, it will glow
    Since the 1950s, global chemical and industrial research institutions have gradually restricted the use of radium to general fields. At this time, the luminous watch has begun to be popular, the material used is Trituin, which has dominated the luminous material of the watch for half a century-trihydrogen. Tritium is an isotope of hydrogen. Like radium, it is a radioactive material, but its radioactivity is much smaller than radium, and it is also much safer.
    Both radium and radon are self-luminous luminous materials, and do not need to absorb energy from the outside to continue to emit light. On Swiss watches during the past fifty years, ‘T Swiss Made T’ is often marked below the six o’clock position, which means that Luminous uses 氚 as its material, and its dosage meets safety standards. The other common ‘T & lt; 25’ of the diving watch means that the radiation of tritium is less than 25 Curie units, which meets the safety standards. Some military watches that use cymbals will also be marked with ‘H3’. The half-life of radon is 12.5 years, that is, the effective life of the noctilucent made by radon is about ten years. After more than ten years, the cormorant began to age, turn yellow, and gradually lost the luminous effect.

    We often see yellow luminescence on antique watches, and that is the aging of luminous luster. Of course, the aging of radon is gradual, unlike radium, which fails as quickly when it encounters water, even aging night light can still emit a faint light. The admixture will also cause some corrosion when it encounters water. Therefore, many old watches that enter the water vapor will have oxidative corrosion around the luminous (such as the pointer or the luminous point on the surface of the disk). We vividly call it a needle. And torch.
    Plutonium In the early 1970s, Japan developed a luminous material. Although it is also based on plutonium, the compound is not easy to oxidize and yellow. The author kept a few old Japanese C-brand watches from the 1970s, and the luminous light is still green, and it can still shine after more than 30 years. Because plutonium is a pure beta particle radiator, the beta ray has a range of only 0.4 cm, and its penetrating power is very weak. It cannot penetrate glass at all. Because the radiation is relatively small, and the amount of luminous spots is not small, it is completely harmless to the user. However, as a luminous producer and processing worker, a large amount of direct contact every day is easy to cause certain harm to the body. Based on the requirements of the United Nations Washington Environmental Protection Convention after the 1980s: plastic case watches are not suitable for coating with tincture. Major brands have gradually reduced the use of radon.

    What I want to mention here is the miniature tritium tube that is still very popular now. The real name of this miniature tritium tube that is popular in the military watch industry is called ‘Tritium Gas Vial’. Since 1989, the US military watch has adopted its standard specification. In 1991, The tritium tracheal military watch was formally assembled by the U.S. military and was widely used in the first Gulf War.

    Today there are two regular radon manufacturers in the world: mb-microtec (Switzerland) and SRB (Canada). The former is a radon supplier for Traser, Luminox and Ball, and the latter is a radon manufacturer for Marathon, Smith & Wesson. The former is about 10% brighter than the latter. This technology was first invented by mb-microtec. In the autumn of 89, Canadian manufacturer Marathon ordered a batch of thoron from mbmicrotec through its then foundry Gallet and explored with mb-microtec the most suitable adhesive between thoron and pointer. Later, Successfully copied the radon trachea. The marathon now has its own watch manufacturer in La Chaux-de-Fonds, Switzerland. mb-microtec first cooperated with the US Stocker & Yale to produce military watches for the US military, and now it produces Traser in Niederwangen, Switzerland (so the radon tube is also called Traser light source).

    According to the product introduction of the Boer watch, Boer Luminous is a pure tritium gas sealed in a miniature mineral glass lamp with a cold-light coating on the inner wall in a very safe and stable form. When the material is cold light, the light tube will emit light 100 times brighter than the traditional coated night light, so that the wearer’s eyes can easily see the time on the dial without adjustment in the dark. Ordinary night light requires external light sources, such as fluorescent lamps and ultraviolet light. Usually the stored energy will gradually diminish in the dark, and it will dim for a maximum of three or four hours to barely see the night light. The luminous principle of Bol night light is similar to that of a television picture tube emitted by the cathode After the electronic excitation, colorful images appeared. So it is not surprising that many enthusiasts who are fascinated by night light will fall in love with military watches that use radon tubes.

    By the mid-90s of the last century, a new type of luminous material was born. It is now very popular Luminova. Luminova is a non-radiative and environmentally friendly material. It was first developed by Japan’s fundamental special chemical group in the 1980s. Until now, the world’s largest supply and sale of Luminova patents and raw materials is still in the hands of Japan’s Radical Chemicals and its holding company United Mineral & Chemical Corporation (UMC).

    In Latin vocabulary, L umi nova means ‘bright night’. Its basic chemical composition is inorganic aluminate, which has very strong light resistance, does not cause discoloration for a long time, and has very good chemical stability, even after years of use Will turn yellow. After 10 to 20 minutes of natural or daylight exposure, it can continue to glow for 8 to 10 hours in the dark. The process of emitting, absorbing, and re-emitting light can be performed permanently. As a luminous material, because it has no radiation, it does not belong to a self-luminous form, but a light-storing form. Only or must be illuminated by a certain light source, it can accumulate light energy in the luminous material, making it glow in the dark. Luminova absorbs the light source and produces a brightness that is greater than the previous chirp, and its life span has reached 25 years. Most modern Swiss watches use Luminova type luminous. More ideally, Luminova can add a variety of colors as a match, such as pink, blue, yellow, red, etc., to create a colorful luminous effect, which adds a lot of rich elements to the design of the watch.
