Application
1. For the manufacture of lead batteries Lead alloy can be used for type, do soldering; Lead is also used to make radioactive radiation, X-ray protective equipment and its compounds are more toxic to the human body, and can accumulate in the human body. Lead is used as a building material, in lead-acetate batteries, in bullets and artillery shells, and in welding, trophies, and some alloys.
2. There is a small amount of natural lead in the Earth's crust. However, due to the accumulation of aluminum-containing minerals and the low melting point (328°C), lead has been used in ancient times. Square lead (PbS) remains the main source of lead extraction to this day. In ancient times, people accidentally threw galena into the fire, it was first burned into oxide, and then reduced by carbon, forming metallic lead.
3. The surface can generate reduced lead carbonate in the air and is protected from internal oxidation. Make lead bricks or clothing to protect against X-rays and other radiation. Used to make alloys. An equal amount of lead and silver can be used to weld metal. Make gold for movable type. An alloy of lead and mirrors, used to make fuses.
4. Lead powder is used as a component of oil-free lubricant for powder metallurgy, and can be used for anti-corrosion coating when mixed with film forming substances
5. Lead powder is a special pigment used in Chinese painting. Now the general sale of tubes and pigment blocks, there are also pigment powder. Traditional Chinese painting pigments, which are generally divided into two categories of material and plant materials from the history of use, should first have minerals, after plants, just as ink first has pine smoke, after oil smoke. The bright color left on the ancient rock painting, according to the test, it was found that mineral pigments were used, and the remarkable characteristics of mineral materials are not easy to fade and bright colors. Plant pigments are mainly extracted from trees and flowers. Lead powder is a mineral material.
Storage Condition
This product should be sealed and stored in a dry, cool environment, should not be exposed to the air for a long time, prevent moisture agglomeration, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidants according to ordinary cargo transport.
