Product Description

 

Tribasic Lead Sulfate

Molecular formula: 3PbO ·PbSO4·H2O
Molecular weight: 990.86

1. Property: It is white, sweet and toxic powder with the specific gravity of 7.10 It can dissolve in , hot thick , ammonium acetate and sodium acetate, partly in acetic acid, but not in water.It will turns to yellow when loses the crystal water at 135ºC, it turns to yellow under sunlight, especially in wet condition.
2.Application: Mainly used for the heat stabilizer of PVC opaque or semi opaque products.such as PVC foam board, PVC foam profile production, or PVC window profile.
3.Package: Plastic weaved bag, lined with PE bag, and 25Kg weight.
4.Storage: It is toxic inorganic product, so it should be kept in a dry and cool storage house with good ventilation, and cannot be
stored or transported with food.

FEATURES
(1) The raw material is processed by cutting, shearing, blowing, floating, and rotating, then become granulated shape and separated greatly; the relative velocity between solid phase and gas phase is great, this strengthens the process of heating exchange.
(2) Design with compact structure and required small occupied area, and the machine is easy to control and maintain.
(3) The hot air enters into the bottom of machine and creates strong rotating airflow; it can wash out material that sticking on the inside surface.
(4) The high temperature area is at the bottom of the machine, the heat sensitive raw material will not directly contact with heating surface. As a result, carbonization and color change problems can be solved.
(5) The dryer is running under negative or micro negative pressure, there is no need other crushing machine to crush raw material, and the circumstance pollution will not occur.
(6) A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and final moisture to satisfy required moisture containing rate and granulation.
