What is the purpose and purpose of rosin perfume?

The role and use of rosin perfume: The role of rosin perfume is to promote welding. In solder, it is an indispensable auxiliary material, and its role is extremely important.

Rosin perfume corresponds to two different liquids:

1. Ordinary rosin perfume: It is a liquid made by dissolving rosin powder in alcohol, which is a flux and is often used in tin wire soldering. Used in soldering operations, it removes oxides and keeps the metal welding surface clean and lubricating for excellent welding.

The smell of the liquid is not strong, and the harm to the human body is light.

2. Solvent pine perfume: Solvent pine perfume is usually used to dilute paint, which is an organic solvent made of octane, nonane, phenyethane, xylene, and trimethylbenzene, which is mainly used for paint dilution and other occasions. Long-term inhalation is harmful to the human body.

Rosin perfume is made of high-quality, refined rosin, formulated with a special solvent, which is highly active, anti-oxidant and easy to dry. The soldering ability is strong, the solder joints are full and smooth, and there is no continuous soldering, virtual soldering and other phenomena. After soldering, the board surface is free of residues, non-sticky, and the surface impedance is high.

and other characteristics, specially designed for the post-treatment coating of PCB boards. Low smoke, low pungent smell, does not pollute the working environment, and does not affect human health; Do not pollute the track and fixture of the soldering machine; The tin speed is fast and the wettability is moderate, even small through-holes can still be tinned.

The role of rosin perfume in the soldering industry is to clean the surface of the product from the oxide of the electronically soldered part.

There is also a pure solvent of rosin perfume, which is used for product dissolution and cleaning effect, and the purchase of such products should be asked clearly in the purchase.

Pine perfumeThe role and use are:

1. Dissolve the oxide film of the welding mother.

In the atmosphere, the surface of the welded base metal is always covered with an oxide film, the thickness of which is about 2 10-9 2 10-8m. During soldering, the oxide film will inevitably prevent the solder from wetting the base metal, and the welding cannot be carried out normally, so the flux must be applied to the surface of the base metal.

The oxide on the surface of the base metal is reduced, so as to achieve the purpose of eliminating the oxide film.

2. Re-oxidation of the welded base metal.

The base metal needs to be heated during the soldering process, and the metal surface accelerates oxidation at high temperatures, so the liquid flux covering the surface of the base metal and solder prevents them from oxidizing.

3. Molten solder tension.

The surface of the molten solder has a certain tension, like rain falling on a lotus leaf, due to the surface tension of the liquid.

It immediately coalesces into bead-shaped water droplets. The surface tension of the molten solder prevents it from diffusing to the surface of the base metal, affecting the normal wetting process. When the flux is applied to the surface of the molten solder, the surface tension of the liquid solder is reduced, and the wetting performance is significantly improved.

4. Protect the welding base metal.

The welded material has destroyed the original surface protective layer during the welding process. A good flux is used after soldering and quickly returns to protecting the soldering material.

Introduction to Pine Perfume

Rosin perfume is a chemical substance, and its main effect is a special flux for soldering. Burning at high temperatures will not produce smoke and have very little pungent odor, which will not affect everyone's work and life. But there's a solvent in pine perfume, rosin, which is specifically used to dilute paint.

There are many harmful chemicals, so be careful when using them.

It is used in the rosin solder industry to decompose the oxide layer on the surface of the product and protect the anti-oxidation effect of the product after welding. The electroplating industry is used for cleaning the products that are being plated and used in the production process.

The chemical name of rosin perfume is trimeric resin.

Rosin is a transparent or translucent irregular lump of varying size, ranging in color from light yellow to dark brown. At room temperature, the texture is brittle, the broken surface is smooth, there is a glass-like luster, and the gas is weak. When heated, it first softens, then melts, and burns to produce yellow-brown smoke.

Preparation of rosin

Choose a pine tree with a diameter of 20 50 cm and make a cut at the trunk 2 meters above the ground; Before cutting a cut, the rough skin should be scraped off, but do not damage the xylem, the length of the scraping surface is 50 60 cm, the width is 25 40 cm, and the scraping surface is 35 50 cm long and 1 cm wide, and the middle groove of the xylem centimeter is deeply penetrated, and the base of the groove is equipped with a fat collector.

It is produced in Jiangsu, Anhui, the western gorge of Henan, the south of the Hanshui basin of Shaanxi, the middle and lower reaches of the Yangtze River, the south of Fujian, Guangdong, the low mountains and the west coast of northern Taiwan, the east slope of Daxiangling in central Sichuan in the west, and the southwest to Guiyang, Bijie and Funing, Yunnan. In the lower reaches of the Yangtze River, it is vertically distributed below 700 meters above sea level, in the middle reaches of the Yangtze River below 1100 1200 meters above sea level, and in the west it is distributed below 1500 meters above sea level.

Then cut the other pair of lateral grooves from the middle groove, and the oleoresin can be continuously collected. It is advisable to harvest at 30 35, that is, in May 10 in the south of the Yangtze River, and in June and September in North China and Northeast China, the collected pine oil is reheated with water, impurities are filtered, and the distillate obtained is separated and removed from the water, which is turpentine. The remaining substance after distillation is condensed to become rosin.

Hello, pro-rosin perfume is a liquid made of rosin powder dissolved in alcohol, the main ingredients are rosin and alcohol, if there are trace reagents, it will also contain a small amount of triethanolamine, hydrooxyic acid and turpentine. Functional use: Rosin perfume is a flux, is a solvent for diluting and blending pigments, mainly used to help soldering, soldering ability is very strong, good oxidation resistance, can remove oxides, make the surface of soldering materials clean and flawless, improve lubricity.

Banana water refers to a mixture of a variety of organic solvents, which is a solvent for blending transparent paint and spray paint, and is mainly used as a solvent and thinner for oil-based paints, spray paints, etc., which can scrub stains.

Rosin perfume refers to two different liquids. Ordinary rosin perfume is often used in tin wire welding, a liquid made by dissolving rosin powder in alcohol, which can remove oxides, keep the metal welding surface clean and lubricated, the liquid odor is not strong, and the harm to the human body is light. The solvent rosin perfume is an organic solvent made of benzenethane, xylene, and trimethylbenzene, which is mainly used for paint dilution and other occasions, which is harmful to the human body.
