関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an explosion-proof cathode 1; it relates to urine a, and relates to an improvement of an explosion-proof structure suitable for, for example, a bush-through explosion-proof color cathode ray tube.

黒色にしている。In a television receiver incorporating a push-through explosion-proof color cathode ray tube, the color shade (1+II) is a tension band or The sides of the tension band and rim band and the sides of the support metal fittings come into view, and if there is light reflection on these sides, the screen becomes difficult to see. The 111th side is black.

) and press the rim band (2) against the rim band (2).
It has a structure in which a support metal fitting (3) is fixed to the corner portion of the rim band (2) and the support metal fitting (3) by means such as welding, and a tension band (4) is stretched over the rim band (2) and the support metal fitting (3). In this case, the rim band (2) is not provided, but there is also an explosion-proof construction in which a tension band is stretched between the direct support fitting (3) and the side wall of the panel via adhesive tape or the like. FIG. 1 shows a state in which a blackened film (4,) is formed on the side surface of the tension band (4) on the side of the tongue panel (1).

が形成されているのが通常である。This type of explosion-proof structure is designed in consideration of the strength and cost necessary to perform the explosion-proof function of a cathode ray tube, such as a color cathode ray tube.
The rim band (2) and support metal fittings (3) are made of mild steel plate with 2 to 5
The tension band (4) is made of high-strength steel plated with 2 to 5 μIn of zinc, and a partial black coating is applied to the side of the panel. Blackened film (4,) consisting of
is usually formed.
さて前述したテンションバンド、リムバンド。Now, the tension band and rim band mentioned above.
支持金具の少なくともパネル（１）ｉｌ（ｌＩＩＩｌｌ
ｌ而を黒色にする方法としては次のような方法があシ、
それぞれ問題点を有している。At least panel (1) of the support fitting (lIIIll
The following method is available to make the color black.
Each has its own problems.
第１に黒色のテープを貼シつける方法があるが、この方
法はテープの粘着力が弱いため、カラー陰極線管の梱包
材と接触して剥れやすく、特にブツシュスルー管が使用
される欧洲までの長期間の輸送ではテープの剥れを皆無
にすることは困難であるし、また使用中にも経時変化で
テープが剥れ易いという問題点がある。The first method is to paste black tape, but this method has a weak adhesive strength, so it comes into contact with the color cathode ray tube packaging material and easily peels off, especially in Europe where push-through tubes are used. It is difficult to eliminate tape peeling during long-term transportation, and there is also the problem that the tape tends to peel off due to changes over time during use.
第２に微量のモリブデン（ＭＯ）やコバルト（ＣＯ）を
含有する亜鉛メッキを３８０℃以上に加熱すると青黒色
が得られるが、しかしこの方法では表面に鉄（Ｆｅ）が
拡散してくるために錆やすく、表面に防錆剤を塗布しな
ければならないという問題点がある。Second, when zinc plating containing small amounts of molybdenum (MO) and cobalt (CO) is heated to 380°C or higher, a blue-black color can be obtained, but this method does not work because iron (Fe) diffuses onto the surface. There is a problem in that it rusts easily and requires the application of a rust preventive agent to the surface.
第３に黒色の塗料を塗布する方法があるが、この方法で
は塗膜が絶縁性のためアースが取りＫ〈いという問題点
がある。A third method is to apply black paint, but this method has the problem that the paint film is insulative, making it difficult to ground.
そのほか、上述の３方法の問題点を解決するために開発
された方法として亜鉛メッキ上に黒色クロメート処理を

、特殊な）易曾、例えば防爆構体に長期間水滴が付着し

。In addition, methods developed to solve the problems of the three methods mentioned above include a method of applying black chromate treatment on the zinc plating and a method of applying paint to the sides or both main surfaces including the sides of the explosion-proof 41°q body. Naturally, these techniques guarantee the generally required rust prevention of iron, but they also require special methods, such as when water droplets adhere to an explosion-proof structure for a long period of time. is eluted and so-called white rust occurs.
このため、第２図に示すようにテンションバンド（４）

ことになる。For this reason, as shown in Figure 2, the tension band (4)
If the white rust (5) oozes out to the side of the supporting metal fittings (3) and the rim band (2), the effect of making them black will be completely lost.
The value of the tube as an explosion-proof cathode ray tube will be halved.
この白錆（５）は次のようにして発生するものと考えら
れる。This white rust (5) is thought to occur as follows.
先ず第１に亜鉛が水と反応して水酸化亜鉛となる。First, zinc reacts with water to form zinc hydroxide.
ｚｎ ＋ ２Ｎ（２０→Ｚｎ （ＯＨ）２ ＋１１２第
２に水酸化１１ｆｆｌ鉛が脱水して酸化亜鉛となる。Zn + 2N (20→Zn (OH)2 +112) Second, hydroxide 11ffl lead is dehydrated to become zinc oxide.
Ｚｎ（ＯＨ）２ →Ｚｔ＋ 十Ｈ２０
第３に水酸化亜鉛が炭酸ガスと反応して塩基性炭酸亜鉛
となる。Zn(OH)2 →Zt+ 10H20 Thirdly, zinc hydroxide reacts with carbon dioxide gas to become basic zinc carbonate.

Oxide 11 thus formed! , lead and basic zinc carbonate cause white rust (5). When zinc forms a local battery with iron, zinc first dissolves out and prevents the iron from rusting, but this zinc causes white rust. This is the cause of (5).
この対策として梱包用木材の含水率を厳しく規制し、ま

に備えているのが現状である。As a countermeasure to this problem, the moisture content of packaging wood is strictly regulated, and a large amount of desiccant is added during packaging to prepare for the lifting of 90,000 yen.
本発明は前述した賭問題点に鑑みなされたものであり、

目的としている。The present invention was made in view of the above-mentioned gambling problem,
The purpose of the present invention is to provide an explosion-proof cathode ray tube, such as a push-through auxiliary explosion color cathode ray tube, which prevents white rust from forming even in special environments and does not reduce its value as a cathode ray tube.

塗装を施した防爆多陰極線管である。That is, the present invention provides an explosion-proof type shade 1 which includes a rimpant tension band on the panel side wall of a cathode ray tube, and an anti-fog 4 (11 pieces) and a support plate made of only the tension band.
! iii.It is an explosion-proof cathode ray tube characterized in that at least the surface of the explosion-proof structure is fully plated with an alloy of aluminum and zinc, and the composition of the alloy plating is 30 to 8% aluminum and 70 to 70% zinc. This is an explosion-proof multi-cathode ray tube which is coated with such an alloy plating and then coated with black chromate or black coating at least in accordance with the panel rules 1111 for cathode ray tubes.

も大きく寄与することができた。In other words, by applying aluminum and zinc alloy plating with the composition described above to the rim band, tension band, and support metal fittings of the explosion-proof structure, it is possible to simultaneously prevent the rust of the iron and zinc materials. (The previous strict regulation of the moisture content of wood for packaging is no longer necessary, and the desiccant used in the past can be reduced to about It also made a significant contribution to reducing the amount of water used.
