It is known for many years that parts made of Ming or Ming alloys, especially heat exchangers used in the A car industry, can be connected to each other under the use of a bile fluoride shaft based cutting agent. The tincture is sprayed on the heat exchanger as an aqueous suspension. In the job preparation or shaft preparation, such as silicon powder or potassium fluorosilicate, when the part is heated to a temperature exceeding the flux and valley point, a stable, non-corrosive compound is formed. Although a method has been disclosed in DEOS 197 49 042, in this method form, the condensed water can be returned to the circulation. The other method parameters are very critical: the concentration of the flux foam must be properly monitored, the heat exchanger must be dried before heating, and the flux foam is also guided back into the cycle, and the flux foam will absorb pollutants. These disadvantages can be avoided if the flux is placed dry on the parts to be joined. This is in the "drying tincture method, the situation of the mouth. Here, the dried flux powder is placed on the part with static electricity. The advantage is that this does not generate any foam, so there is no need to monitor the foam concentration and it is no longer necessary for the part. Preparation-separate drying steps, and more moisture-free coagulation 2 'The core task of the present invention is to provide-welding based on fluoxamic acid, which can be easily aerated in aerodynamics, and it can be easily dried in dry matter. It can be easily attached to the sprayed parts, and it is suitable to be used in the method of drying flux ("fluxing"). This task is solved by applying for flux in the special area.

Description of the invention (2 ·) There is a fuzz in the domain capability of the part J1. The current profit-maker is when the smaller or larger particles are included in the flux, and the proportion is formulated according to a specific rule. According to the present invention, it can be used as a dry solder paste. The characteristics of a flux based on alkali gas sulphate are its volume distribution of particles, which is roughly between curve 1 and curve 2 in FIG. The particle size is measured by laser refraction. In a preferential flux, the volume distribution of particles is roughly between curve 1 and curve 2 in Fig. 11. Fig. 10 shows that in the sense of the present invention, the lower limit (curve i) and the upper limit (curve 2) of the powder can be used in the volume distribution curve. This refers to the cumulative volume distribution of the powder calculated in% relative to the particle size. The cumulative volume distribution of the liniment powder is one above or between the curve i and the curve 2 in Fig. 10, a powder within the meaning of the present invention. The comparison of the cumulative volume distribution and particle size between curves 1 and 2 in Figure 10 is summarized in Table A below. The cumulative volume distribution of the disc is compared with the grains between curve 1 and curve 2 in Figure 10 (please read the precautions on the back before filling in this page) n ϋ ϋ nn ϋ i I nn ϋ I · ϋ ϋ ft— · I line- 6- Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 523437 Α7 Β7 V.

Apparatus and method: A measuring instrument (Binks-Sames powder fluidity indicator AS 100-451 195) for measuring powder liquefaction and powder flowability is fixed on an oscillator (FritschL-24). A neighbouring measuring instrument has a liquefied cylinder with a breathable film at the bottom. 250 grams of powder to be measured each time was placed on a cylinder, the shaker was turned on, and a uniform (controlled according to diameter) dry nitrogen gas flow was introduced into the powder through a breathable film. The powder will swell. To adjust the balance, allow the gas to act for one minute. By measuring the height before and after expansion, the degree of liquefaction of each powder can be calculated. The degree of liquefaction and flowability of each powder is known through the so-called "spray coefficient". This spray coefficient is a combination of the expansion coefficient (liquefiable degree) and the collective flow (fluidity) of the powder. This spray factor is a very important factor for dry welding applications. This is measured as follows: as described above, for each powder to be studied, it expands in a liquefied cylinder. After 30 minutes, a suitable air hole on the side of the cylinder was opened, and the powder leaving through these air holes was captured and weighed in a beaker. The ratio of the captured powder relative to the time unit of 0.5 minutes is hereinafter referred to as the "spray coefficient." For a better explanation, the spray coefficient of the powder that can be liquefied and flowable is pointed out. It is 140. The spray coefficient of extremely swellable and extremely flowable powder is, for example, 7. In Table 3 below, it is pure powder. 210 X 297 mm) -12-(Please read the notes on the back before filling out this page) Order --------- line!

This is shown graphically in Figure 3. As can be seen from the above, it is the percentage amount of powder 1 in the mixture at a spray coefficient of g / 0.5 minute. This proves that the small amount contained in the powder has a significant effect on the fluidity. The research on the distribution of aluminum parts is too small and the research on the attachment ability of aluminum parts: The adhesion ability is measured by a very simple method, which can make good conclusions about the measured powder technology for dry welding. . A flat, quadrilateral aluminum plate with a size of 0.5m × 0.5m is placed on one side electrostatically. The spray coating is required to be studied and the welding powder is dried. The loaded flux is weighed, and the tray is allowed to fall from a height of 5 cm in the vertical position, and the loss of the flux is recorded as a percentage of the original flux load. For powders, 10 measurements are taken at a time. Poorly adhered powders show a relatively high weight loss compared to the trace weight loss of the powders used in accordance with the present invention (see Powder 3 and Powder 4).

Description of the invention (14 ·) Brief description of the drawings The descriptions of Figures 1 to 11 are as follows: Figures 1 and 2 are the optical results of the statistical values of the particle size distribution in Tables 1 and 2. Figure 2 is a graph of the dependence of the zero lean fog coefficient on the powder mixture formulation. The liquefiability and flowability of the powder are obtained from the spray coefficient. Figures 4 to 7 show the results of comparing the flux loading with the time of powder 1 and powder 2. Figure 8 clearly shows the results of flux loading with powder 3. The optical results of the particle size distribution of powder 3 can be found in Figure 10. Figure 9 shows the results of flux loading on the powder 4 under study. Figures 10 and 11 clearly show the upper and lower limits of the volume distribution curve of the powder to which the present invention is applicable. ------------ 1 -------- Order: -------- Line_ (Please read the notes on the back before filling this page) Wisdom of the Ministry of Economic Affairs Appropriately printed on paper by the Consumer Cooperatives of the Property Bureau (CN quasi-standard national standard 0 971 2 X 10 (2 rules
