Anti sling liquid for welding

Abstract

The invention relates to chemical paint, in particular to a soldering anti-spattering liquid which can prevent a solder ball formed by spattering from being adhered to a soldered product in soldering. The soldering anti-spattering liquid consists of the following raw materials according to the weight ratio: the weight ratio of water to calcium oxide to ink with concentration of 1 percent is equal to 100.0 to 20.0-30.0 to 0.5-1.0. Therefore, the soldering anti-spattering liquid has good erasable property, and is easy to remove the solder ball formed in soldering; in addition, the soldering anti-spattering liquid does not need other cleaning reagents to remove the trace remained by spattered liquid, produces small smog and is favorable for physical health of operators.

Description

Technical field [0001] The invention relates to a chemical coating, in particular to a welding anti-spatter liquid for preventing the solder balls formed by spatter from adhering to the products to be welded during welding. Background technique [0002] Welding is a metal processing method that uses heat or pressure or both, with or without filler metal, to achieve interatomic bonding of the welded metal. Spatter is a common undesirable phenomenon during welding. During welding operations, solvents boil and sparks splash around and fall on both sides of the weld. After cooling, they form irregular solder balls, which adhere to the surface of the product and require polishing and cleaning. It is labor-intensive and effective. The law is low, especially when it falls on the surface of irregular products, grinding is very laborious and also affects the post-welding operation. The shortcomings of the current welding anti-spatter liquid on the market are: Although the solder balls for...

Splash is a common adverse phenomenon during welding. During welding, the solvent boils and sparks splash around, falling on both sides of the weld, and forming irregular solder balls after cooling, which adhere to the surface of the product and require grinding and cleaning. The labor intensity is high and the efficiency is high. The law is low, especially if it falls on the surface of the irregular product, the grinding is very troublesome, and it also affects the post-welding operation

The disadvantages of the welding anti-splash liquid currently on the market are: although the solder balls formed by splashing after use are easy to remove, the welder will feel peculiar smell, sore eyes, and heavy oily smoke during operation, which will affect health; when the anti-splash liquid is used, Generally, it is sprayed or applied on the surface of the product, and the liquid contains a variety of harmful elements, which not only affect the surface of the product, but also make it difficult to remove its own traces. Before painting, a large amount of paint thinner (thinner) should be used to remove the residual anti-splash If the anti-splash liquid is not completely removed, the surface of the paint is prone to wrinkling, paint peeling, and oil return after painting.
