Embodiment Construction
[0020] The manufacturing method of the compound preparation for repairing mulberry bark trauma is characterized in that:
[0021] The first step is to mix 100 parts by weight of water and 15 parts by weight of sodium metasilicate pentahydrate. Sodium metasilicate pentahydrate (Na 2 Si O 3 ·5H 2 O): Monoclinic columnar crystal, melting point 72.2℃, easily soluble in water and dilute lye.
[0022] Then, proceed to the second step.
[0023] In the second step, add 3 parts by weight of boric acid to the liquid of the first step, and stir for 10 to 15 minutes. Boric acid (Molecular formula: H 3 BO 3 ) Is an inorganic acid, it is white powder or transparent crystal, soluble in water. The stirring tool used is a plastic stick.
[0024] Then, proceed to the third step.
[0025] In the third step, add 30 parts by weight of ferrous chloride tetrahydrate (FeCl 2 ·4H 2 O) and stir for 10 to 15 minutes. The stirring tool used is a plastic stick.
[0026] The superscripts (footmarks) of chemical ...
