V. Description of the invention (A7 B7 Shun's extremely heat-bonded first-generation heat-mechanical zinc composite cloth is formed of several layers of gold and combined with or coated with structural holes He is divided into two materials, according to the shape of the material. The material is small. The small porcelain is a hard porcelain, and the porcelain is relatively thick. The zinc and gold are sealed in the layer of the more porcelain. The gold pottery and gold film P is a material variant coating. The layer is coated with 00 heat and low shape to make porcelain. This is two groups of gold. The 15 is compared to the inner strength. The first is the frame-shaped hole shadow gold. Should be based on the rationale and the rate of change from the point In addition to the cell meeting, the one-oxygen melting is reversed, and it is also slower than the higher part of the small porcelain layer. Bao San or Yi Tu and this can be used to save the time or save the time as the thimble embroidered thixotropic embroidered body of the first Jindi spray. It is a kind of film, this cell should not be porcelain. The belt layer is consistent with Taoman porcelain gold, and is coated with steel. It is a co-production. Due to the existence of porcelain and other objects and porcelain, the high group rate film gold. Cobalt-, Tao this combination, the number of ceramics Compared with the rapid coating, the film formation is less or due to the change of the film. Oxygen is the degree of spraying. The shape of the spray is reduced by the coating and the material is intermittent. Expanded machine gold | binding (please read the precautions on the back before filling out this page).

Invention description (^) When the upper layer is formed, 3-4 circular peeling strips with a diameter of about 3mm are produced on the surface layer. In continuous hot dip galvanizing The actual use result of the tank stick of the present invention with three coating layers applied on-line is recognized that although the durability is shorter due to the experimental immersion test result using the external stress of the steel belt, it is still 120 days or more. Galvanized wire, the results of the tank stick test using the coating film layer of the above comparative example, indicating that round peeling occurred after 24 days, also confirming the advantages of the present invention.

Invention Description (Each) is next to the rate stop. Make the reduction of the frequency line instrument bath full from the production of the stick to the Ankun, the rate of rejuvenation is due to the low cost of the tank, and the role is to reduce the risk, Η bath protection The operation of the high-certification zinc province is accompanied by a variable protection plating line, which can lead to frequent production temperature, which is the rate of life of the stick. The frequency C is good. Make less use of sticks and change them to reduce the amount of stop. The less line can be changed due to less heat. The output of cans can be reduced and the bath addition and subtraction can be caused by the use of the bell. Melt and converge, but add to it, plated in heat The frequency of the stable line is increased by the addition of the provincial bath, which does not produce life sticks. This is the time for the dynamic game to change the size and the work is used less. ---- 丨. ^.-I (Please read the precautions on the back before filling in this page) The paper standard printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs is applicable to the Chinese National Standard (CNS) Α4 specification (2Ι0Χ297mm)
