What exactly is Guanyin Tu?
It's actually kaolin, so can you really eat kaolin?
The picture
Chemical formula: a clay mineral, 2SiO2·Al2O3·2H2O
Structure: Layered silicate minerals
The name kaolinite comes from the name "Kaolin", a mountain near Jingdezhen, Jiangxi Province, China. Kaolinite produced here has long enjoyed a good reputation at home and abroad because of its fine quality.
Other names: also known as "kaolin", "China clay", Guanyin clay, mud mud eel
Physical properties:
Pure white, because of impurities can be dyed into different shades of yellow, brown, red, green, blue and other colors;
The dense block has an earthy or waxy luster.
Soil-like block with rough feeling, when dry with absorbency (sticky tongue), wet with plasticity, but not expansion, cation exchange performance is poor.
Causes:
Kaolinite is one of the most widely distributed and main components of clay minerals.
They are mainly igneous rocks and metamorphic rocks rich in aluminosilicates, which are the products of weathering or low temperature hydrothermal metasomatism in acidic medium environment.
Kaolin is a fine soil, which contains many minerals. In addition, the human body also needs a small amount of it. When people are hungry, they can get temporary satisfaction by eating it, so it is called the "Guanyin earth".
Although can have the effect of abdomen, but indigestible, abdomen is appearance only, eat to go in cannot absorb, eduction body is difficult again, edible much can cause abdominal distension, body uncomfortable a lot of symptoms.
Eat soil is not enough to eat water, kaolin once encountered water will become sticky, into the esophagus harm is great, once because of eating soil killed many people.
Conclusion: Kaolin is inedible, but it has many important uses because of its unique properties.
PUDA Kaolin packing machine:
Kaolin is fine and light powder , PUDA will use valve bag packing machine with screw feeder for it. Valve bag can limit air dust, screw feeder can stir kaolin evenly.
