Embodiment 1
[0030] An oily suspended magnesium and calcium fertilizer, comprising the following components: 112g of water, 40g of magnesium hydroxide ore powder (the content of magnesium hydroxide is 87%), 3g of light calcium carbonate (the content of calcium carbonate is 99%), wetting agent MSR-TT1 4g, dispersant MSD-511 8g, xanthan gum 0.4g, aluminum magnesium silicate 4.0g, vegetable oil 20g, propylene glycol 8.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.
[0031] Prepare above-mentioned oily suspension magnesium, calcium fertilizer adopt such as figure 1 Described device, specific method comprises the steps:
[0032] 1) Add a specified amount of water (factory tap water) into the high-speed shearing machine 1, start the high-speed shearing machine 1, adjust the speed to 200r / min, and add the weighed magnesium hydroxide ore powder and light calcium carbonate ore powder in turn , Wetting agent MSR-TT1, dispersant MSD-511, thickener xanthan gum and aluminum magnesium sili...
Embodiment 2
[0039] The difference with embodiment 1 is:
[0040] An oily suspended magnesium, calcium fertilizer comprises the following components: water 147g, magnesium hydroxide ore powder 30g (magnesium hydroxide content is 87%), light calcium carbonate (calcium carbonate content is 99%) 1.6g, wetting Agent MSR-TT1 2g, dispersant MSD-511 4g, xanthan gum 0.2g, magnesium aluminum silicate 1.0g, vegetable oil 10g, propylene glycol 4.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.
Embodiment 3
[0042] The difference with embodiment 1 is:
[0043] An oily suspended magnesium, calcium fertilizer comprises the following components: 128g of water, 34g of magnesium hydroxide ore powder (magnesium hydroxide content is 87%), light calcium carbonate (calcium carbonate content is 99%) 2.4g, wetting Agent MSR-TT1 3g, dispersant MSD-511 6g, xanthan gum 0.3g, magnesium aluminum silicate 4.0g, vegetable oil 16.0g, propylene glycol 6.0g, adjust the pH between 8.0-9.0 with potassium hydroxide.
[0044] The oily suspension magnesium and calcium fertilizers obtained in Examples 1, 2, and 3 are detected, and the results are shown in the table below. It can be seen that the products prepared in the three examples are all in a homogeneous suspension state, and have good automatic dispersion. Rates are all above 95%, and Examples 1 and 3 have reached more than 99%, and the particle size has reached nanoscale.
