example 1
[0011] Example 1 Take 10kg of acrylic acid, add 20kg of 20-45% sodium hydroxide to neutralize it, add 40kg of water to absorb the heat of polymerization, adjust the pH of the aqueous solution to PH7-14, add free radical initiator potassium persulfate or persulfate per liter of acrylic acid 0.1-0.6g Ammonium sulfate, put the aqueous solution to polymerize and cool to room temperature to obtain the hydrosol of polyacrylic acid sodium salt or ammonium salt, which contains 4-10% of sodium polyacrylate and 90-85% of water.
example 2
[0012] Example 2 Take 10kg of acrylic acid, add 20kg of 20-29% ammonia water for neutralization, add 20kg of water to absorb the heat of polymerization, adjust the pH of the aqueous solution to PH7-14, add free radical initiator potassium persulfate or ammonium persulfate at a rate of 0.1-0.6g per liter of acrylic acid , put the aqueous solution to polymerize and cool to room temperature to obtain the aqueous sol of polyacrylic acid sodium salt or ammonium salt, which contains 4-10% of ammonium polyacrylate and 90-85% of water.
example 3
[0013] Example 3 The aqueous sol of polyacrylic acid sodium salt or ammonium salt obtained in the above two examples was dried at 150°C until it was easily crushed, and then crushed through a 20-mesh sieve to obtain polyacrylic acid gel. The content of polyacrylic acid sodium salt or ammonium salt: 98%.
[0014] apply effects
[0015] On four smoky red soils (acidic, slightly acidic, slightly alkaline, and alkaline) and one potting soil, wheat stalks, corn stalks, rapeseed cakes were added with chemical fertilizers, and German Agrosol was applied before transplanting flue-cured tobacco Soil improver and additional application of PAA salt soil conditioner of the present invention, compared with appropriate amount of single application of chemical fertilizer and large amount of single application of chemical fertilizer, to study the impact of application of organic matter on soil properties, flue-cured tobacco yield, output value and quality of tobacco leaves. The results showed...
