Description
Technical Field
The invention relates to a heat-insulating container and a processing technology thereof, in particular to a solder and a heat-insulating container welded by the solder.
Background
At present, many people can fill water in a thermos cup and also can fill acidic drinks such as fruit juice, fruit tea, fruit powder granules, carbonated beverages and the like. The main material of the existing heat preservation container (especially the vacuum cup) is stainless steel, namely, the inner container and the outer shell of the vacuum cup are both made of stainless steel. The stainless steel has a high melting point and does not release undesirable substances due to high-temperature melting. However, stainless steel is most afraid of strong acid, and if drinks with strong acid are loaded for a long time, the inner container of the stainless steel is likely to be damaged. The damaged inner container of the stainless steel vacuum cup can cause the chromium, nickel and manganese elements contained in the stainless steel to migrate rapidly, and more heavy metals are likely to migrate in a short time. Moreover, the migration is often unrecognizable to the naked eye, which brings hidden dangers to the health of the user. Some people also like to soak the traditional Chinese medicine in a vacuum cup, so that the traditional Chinese medicine is convenient to carry and drink. However, a large amount of acidic substances are dissolved in the decocted traditional Chinese medicine, and the acidic substances are easy to react with chemical substances contained in the inner wall of the vacuum cup and are dissolved in the decoction, so that adverse effects are generated on the human body. The titanium vacuum cup has the advantages that strong acid and strong alkali resistance is not needed, the titanium vacuum cup is in contact with the traditional Chinese medicine, any chemical reaction is not generated, and the safety and the convenient carrying of the traditional Chinese medicine can be realized. No matter what the cup is, the cup can be filled with coffee, fruit juice, fruit tea, fruit powder granules, carbonated beverage and milk, no heavy metal is separated out, and the cup is not limited to what the cup wants to drink, and even people with metal allergy can use the cup without worry. Secondly, the method comprises the following steps: titanium is beneficial to the human body, and this light metal has the ability to regulate the body's natural electrical current through cell ionization. Titanium has special current characteristics, has beneficial physiological effect on human body, is chemically stable, cannot change or deteriorate with time, and is beneficial to physical and psychological health of human body. Therefore, the titanium product can achieve the effects of relaxing spirit, relaxing muscles and improving motor function. Thirdly, the method comprises the following steps: titanium oxide is an inorganic compound of titanium and oxygen and is generally used as food additives, paint, cosmetic additives and the like. Titanium oxide is classified into rutile type and anatase type according to its crystal structure. Among them, anatase type has a bactericidal effect. The titanium oxide thin film oxidized at the positive electrode has a temperature characteristic in the chemical synthesis treatment, and this characteristic causes the titanium oxide thin film to be anatase crystals and formed on the surface of titanium. The titanium surface is an oxide film, so that the iron rust taste of metal products is not felt, the peculiar smell of the beverage is not generated, and the taste can be fresh and cool. The mechanism of the photo-antibacterial action is that after the titanium oxide receives light, positive holes and negative electrons on the surface of the titanium oxide are released. This energy dissolves with oxygen contained in water to form active oxygen, and hydrogen and oxygen are produced by decomposing water. In this process, the beverage is further mellow in taste because the organic substances are sterilized and decomposed by the action of hydrogen and active oxygen, and also the foreign germs, sour taste, and the like are decomposed. Fourthly: titanium is known as biological metal, widely used for medical appliances and human body implantation, is a universally recognized healthy and nontoxic element in the world, has no influence on the vegetative nerve and gustatory nerve of people, and is resistant to strong acid and strong alkali. Therefore, the titanium vacuum cup is slightly expensive, but has obvious benefits for human bodies.
In order to solve the problems, the Chinese patent application publication (publication number: CN 110432727A) discloses a vacuum cup with outer steel and inner titanium and a vacuumizing process. It comprises the following steps: manufacturing a double-layer inner container, a titanium alloy inner container layer and a stainless steel inner container layer. Manufacturing a shell, comprising the following steps: a stainless steel layer: stainless steel pipe material, cutting pipe, water expanding, forming, rolling thread after products are complete, and forming the outer shell; and (5) stamping the outsole to form and vacuumizing holes. Manufacturing a finished cup body, comprising the following steps: the inner container shell is matched with a buckle for welding, and the outer bottom is welded (the upper air suction sheet is welded); placing glass cement after welding; the glass cement is heated and melted by vacuum equipment to reach a high vacuum state after being cooled. The vacuum interlayer sealing performance of the vacuum cup is greatly improved and the service life of the vacuum cup is prolonged by adopting the double-layer inner titanium alloy as the inner container, the stainless steel of the outermost shell, the 3-layer process and the hollow position vacuum layer in the inner container and the shell.
However, at present, the titanium material and the stainless steel have poor welding fastness, even the titanium material and the stainless steel cannot be welded together by adopting a common welding mode, and the quality of the heat preservation container of the titanium inner container and the stainless steel shell is poor.
