Red Cabb Chemical Engineering Aspects
A Brief Introduction to the Chemical Industry
In Guangdong, there is Qi Siong, whose color is as red as Dan, and everyone calls it Chi Siong. Its shape is different from that of Chang Siong, and the leaves are broad and thick, and the stems are strong and tough.
The planting of Chi Siong is not good unless the ground is fertile and the water is sweet. Its soil should be loose and fertile, and it should be cultivated with fertile soil, and filled with clear springs, so that it can flourish. Sometimes when planting, it is spring and autumn, and those who nurture it need to pay attention to the time and place, and follow its own nature.
As for taking Chi Siong for use, there are many chemical methods. Pick its leaves, expose them to dry, and break them up like the end. Soak them in water, and the color will gradually emerge, like the morning This liquid can be used for dyeing, and the color of the silk will be bright and long-lasting, and it will not fade over time.
If the stem is refined by fire, a paste-like thing can be obtained, which is condensed and firm, and its quality is sticky, which can be glued. The sticky wood and stone thing is very strong, and it is not easy to take off although it is invaded by wind and rain.
There are also those who combine red songsong with various medicines. By the method of processing, or boiling or steaming, or baking or drying, it can be made into pellet powder, which can treat various diseases and has different effects.
The Cantonese people make good use of red songsong, which is used in all things in the chemical industry, passed down from generation to generation, and their skills are increasingly refined. With the ability of red s
