Product name：

BTB3000 Barium Sulfate

Characters：
　　Prismatic Crystal belongs to Crystal or bright amorphous power, relatively density 4.15(15℃)，melting point 1580℃, It ‘s chemical character is stable and also a kind of excellent fame dye because of it’s strong ability in obstructing and absorption against energetic ray.. Besides it has good dispersivity, stability and excellent glossiness. Moreover it has perfect ability in space division to titanium dioxide and other colorful particles, meanwhile save the cost quite a lot.

Use：
　　Used mainly in industries such as top grade paint, power coating, plastic, rubber, paper—making and printing ink.

Production tech：
　　Natural Barium Sulfate are processed into super fine power.

Package：
　　　Paper—plastic compound bag or Outer bag woven plastic , inner pellicle bag . Net weight 25kg

Test method ：
　　Determination on Barium Sulfate:Melt sample with the mixture of Natrium Carbonate and Kalium Carbonate at high temperature, in this way Sulfate becomes Barium Carbonate. Then use continue determination by weight---method
　　Test PH value:According toGB/T1717，turn setting for 5min into setting for 10min
　　Test Iron:Operate according toGB/T3049
　　Determination of brightness:To make bright board use sample depressor. Compare it standard sample of magnesium oxide.
　　Test distribution of particle size:Prepared a watery suspension, test a certain potion’s concentration under liquid surface and calculate the real particle diameter there.
　　Test oil absorption:Test the quantity of sample’s absorption of fine linseed oil under regular conditions
　　Test water soluble material%:Operate according to the instructions of GB/T5211.2.
　　Test tailover:Scatter sample in water and put them into screen, repeat several times .Flush substance on screen until lotion is clear, just then dry and weigh it.
