Because the riding section generates a money screen, the geometry of the shielding cover needs to be in line with the camp when the color image tube is operated. The pattern of the light section is consistent. When the aperture geometry of the shield at the operating temperature matches the distribution of the fluorescent section on the inner surface of the screen, the maximum collision accuracy of the electron beam on the glorious section is reached, because only a small amount Some of the emitted electrons passed through the shield and hit the cymbal section, and most of the electrons directly hit the shield. As a result, the shield was heated up to 8 ° (rc), which caused the shield's geometry to change. Change, resulting in the rounding of the shield (rounding effect). The aperture geometry of the shield no longer matches the pattern of the fluorescent section, so that the electronic impact is inaccurate. The color manufacturing quality of the screen is disturbed. Due to the high contrast image, Shields in different areas can be heated to different degrees of hardness, so a partial rounding (local rounding) of the shield can be obtained, and aberrations also occur when the tolerance is exceeded. Many people have tried different methods, which are intended to limit or avoid These unfavorable thermal behaviors of the shield. Therefore, various solutions have been proposed,.

Description of the Invention (Λ) The Central Standards Bureau of the Ministry of Economic Affairs, Zhenggong Consumer Cooperative Co., Ltd. ^ to limit the overheating of the shield. Today, Patent No. 887, 82 δ suggests that a porous manganese dioxide layer is provided on the metal wide-hole cover plate and a thin metal aluminum layer is provided on the top end thereof. The aluminum layer only touches the perforated mask at the edges. It should have conductivity and electron absorption. Γ Place another layer of graphite, nickel oxide or nickel iron on the aluminum layer. The porosity of the bell oxide layer is due to almost entirely the generation of individually arranged particles. This layer forms a sandwich structure with a thin aluminum layer. Due to this layer structure, the heat generated by the electron collision is often excluded from the metal porous cover and emitted in the opposite direction. This solution has various disadvantages. It has been found that excluding the generated heat from the porous cover plate cannot prove to be feasible, because most of the = is not generated in the cover layer and the graphite layer covering it, but in the porous cover plate. The electron reflection, electron absorption and heating properties of the aluminum layer are too low. 6 The heat-insulating sandwich structure, which is placed on top of the porous cover plate, currently causes a negative effect: it is very difficult to discharge heat. In addition, a heat-resistant porous cover surface is provided, and a surface layer containing heavy metals is placed thereon. The heat-insulating layer is composed of a porous solid coated with a binder on a metal porous cover. After two layers, that is, a thermal insulation layer and a heavy metal-containing surface layer, the technical turn-on amount placed on top of it was found to be quite high. < Summary of the invention > The object of the present invention is to provide a heat-insulating layer and another surface layer. The heat-insulating layer, due to its heat-insulating effect, largely avoids heat transfer to the porous cover plate and simultaneously reduces the rounding effect without coating . The purpose of the present invention is to apply the features of items 丨, 2 and 21 of the scope of patent application. 5 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm). --- 1T ------ ^ (Please read the notes on the back before filling in this card.)

The development of this fortune is based on the present invention, such as the attached subsidiary of the patent scope, which intends to provide a shielding cover for the cathode end surface and veneer part with a heat insulation layer, which is covered by a metal compound in the hole. The porous structure is composed of particles, so that the effect of reflecting Hi electrons is directly generated in this layer. Because of this layer: the heat released by this is easily transferred to the inside of the tube rather than to the porous cover. Because there is no surface layer, it does not prevent heat release into the tube = inside. In this way, it is possible to extremely avoid the temperature difference between the porous cover plate and the round portion. Surprisingly, it was found that a significantly reduced rounding effect was obtained without even adding an insulating layer of a heavy metal compound according to item 2 of the patent application. The thermal insulation layer of the present invention is composed of particles having a porous structure coated in an adhesive. Advantageously, the manufacturing method of the shielding cover of the present invention includes directly incorporating particles of a porous structure having a heavy metal compound before coating the porous cover. Incorporating heavy metals and / or heavy metal compounds into the porous structure by Λ 'can be effectively performed in phase. According to the development of the present invention in item 3 of the scope of the patent application, it is referred to particles having a porous structure that has ion exchange properties. The use of water-soluble heavy metal compounds is such that the situation in which heavy metal ions are incorporated into the porous structure is not complicated and is exchanged with ions present therein, such as alkali metal ions. Can be advantageously used with zeolite-selected from clay minerals or metal phosphates, for example, the size of this paper is applicable to the Chinese National Standard (CNS) Λ4 specification (210 X 297), 袈 ------ II (please read the back first Please fill in this page for the matters needing attention j Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 ------ B7_ · V.

According to another development of the invention of the scope of the patent application No. 7, the inorganic particles lacking an ionomer are regarded as having a porous structure. Particles. In this respect, porous particles made of oxides, stone or dish materials such as metal oxides, fossils and metal silicates are particularly suitable. Among these, silicon Acids, osmium dioxide and titanium dioxide are suitable as oxide particles having a porous structure. In particular, porous silica materials include many types of zeolites. Particularly suitable are molecular sieves, such as natural molecular sieves of chabazite, mordenite, and edonite '' Faujasite stone (faujasite ^ ain〇ptU〇lite, and synthetic zeolites A'X, Y, L, / 5 and / or these ZSM type. There are so many types of zeolites that they cannot be listed here one by one. Surprisingly, it has been found that even with a thin layer applied to the cover, the effective thermal insulation of the shield can be obtained. Similarly, when using porous phosphate solids, for example, they can be made synthetically and classified as large , Medium and small pore type so-called Minglin acid salt, Shi Xi _ acid salt and metal aluminophosphate also get a favorable effect. Other suitable porous solids are clay minerals of alternating lime, layered Phosphate and silicone, and various other known acid salts. ^^ 1- mu 11 ml m 1-- -1 I · I- nn nn —i-* T (谙 Please read the notes on the back before filling this page 〕 CNS) AAim (A7 B7 'V. Hair Explanatory note (f) The heavy metal compound incorporated into the porous structure according to the present invention can be fixed by drying or pyrolysis. The next action of the sulfide ion is to obtain a sulfide heavy metal compound, which is added for thermal dissipation due to blackening The positive effect of the pores. During the manufacturing period, the pore size of the porous structure particles can be changed in a wide range, so that depending on the needs, it can be extremely effective to load heavy metals. In particular, the crystallinity and glassy Silicates, phosphates, and borates are used as adhesives for insulation, and in this regard, water glass and metal phosphates have been found to be useful. The adhesive has high adhesion properties on the surface of the cover, and it is very significant to produce a mechanically stable coating that obtains additional spatial stability of the porous cover. The coating of the layers is carried out according to coating procedures known per se, for example the surface of the spray hood and can thus be applied at a significantly advantageous cost. Generally, the insulating layer has a layer thickness of 10 to 50 micrometers and an average particle size of 1 to 10 micrometers. An advantage of the present invention is that the rounding behavior of the ion mask is significantly improved, whereby the use of expensive invariant steel to manufacture the mask can be eliminated in many cases. < Simple description of the diagram > Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) The present invention will be explained in more detail with related drawings and several specific embodiments Figure 1 shows a sectional view of a color video tube; Figure 2 shows a top view of a shield. ≪ Comparison of component names and symbols in the drawing > 1: Vacuum tube 8 This paper size applies to China National Standard (CNS) A4 specifications (210X297 mm) A7 printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs " ----------------- B7 V.
