Embodiment 1
[0038] Take the raw materials by the following weight: sodium hexametaphosphate 19.5kg, calcium hydrogen phosphate 7.18kg;
[0039] In the V-shaped mixer (the V-shaped mixer can be purchased from commercial sources, what the present invention used is the pharmaceutical production equipment, VHT type, is produced by Tianjin Traditional Chinese Medicine Machinery Factory), the above-mentioned raw materials were mixed for 30 minutes, and then transferred to Reaction furnace lined with high-temperature-resistant quartz (the reaction furnace lined with high-temperature-resistant quartz is unshaped equipment, and the core component of the reactor is an ark made of sintered quartz, with a size of 960x460x260 mm and an inner cavity of 950x450x250 mm, with a volume of about 100 liters. The reactor is surrounded by high-silicon bricks for insulation, and silicon carbide rods are used as heating elements in the middle. The size of the entire reaction furnace is 1450x1100x800 mm) for melti...
Embodiment 2
[0050] Weigh the raw materials according to the following weight: sodium tripolyphosphate 60kg, calcium hydrogen phosphate 40kg; divide the above raw materials into a VHT V-shaped mixer (Tianjin Traditional Chinese Medicine Machinery Factory) and mix them for 30 minutes in 2 times. The reaction furnace of lining (the structure of reaction furnace and its material are with embodiment 1), control melting temperature 900-950 ℃, reaction temperature 1100-1200 ℃, total heating time 1-2 hour. After the reaction, pour into the mold (the mold is the same as in Example 1), and when the mold is cooled to 500° C., the mold can be demoulded, and the finished product can be obtained after annealing.
[0051] The properties of the product obtained are as follows:
[0052] Appearance: colorless transparent or microstrip blue balls, 18-20 mm in diameter;
[0053] Solubility: 3.5-5.5 mg / g / day;
[0054] Chemical composition: P 2 o 5 66.7% (wt)
[0055] CaO 13.6% ...
Embodiment 3
[0061] Take the raw materials by the following weight: sodium hexametaphosphate 72.2kg, calcium hydrogen phosphate 27.8kg; the above-mentioned raw materials were mixed for 30 minutes in the V-shaped mixer (same as Example 1) twice, and transferred to the The reaction furnace of lining (furnace structure and its material are the same as embodiment 1) controls melting temperature 900-950 ℃, reaction temperature 1100-1200 ℃, and total heating time 1-2 hour. After the reaction, pour into the mold (the mold is the same as in Example 1), and when the mold is cooled to 500° C., the mold can be demoulded, and the finished product can be obtained after annealing.
[0062] The properties of the product obtained are as follows:
[0063] Appearance: colorless transparent or microstrip blue balls, 18-20 mm in diameter;
[0064] Solubility: 1.5-2.8 mg / g / day;
[0065] Chemical composition: P 2 o 5 62.8% (wt)
[0066] CaO 13-14% (wt)
[0067] SiO 2...
