Embodiment Construction
[0020] The preparation method of the compound preparation of repairing apricot bark trauma is characterized in that:
[0021] The first step, the water that is 100 parts by weight, the sodium metasilicate pentahydrate that is 20 parts by weight are stirred evenly, sodium metasilicate pentahydrate (Na 2 SiO 3 ·5H 2 O): Monoclinic columnar crystal, melting point 72.2°C, easily soluble in water and dilute lye.
[0022] Then, proceed to the second step.
[0023] In the second step, 3 parts by weight of boric acid are added to the liquid in the first step, and stirred for 10 minutes to 15 minutes. Boronic acid (molecular formula: H 3 BO 3 ) is an inorganic acid, it is white powder or transparent crystal, soluble in water. The stirrer used was a plastic stick.
[0024] Then, proceed to the third step.
[0025] The 3rd step, adding the ferrous chloride tetrahydrate (FeCl4) that is 30 parts by weight in the liquid of the second step 2 4H 2 O), and stir for 10 to 15 minutes...
