Compliance test result:
Being evaluated with ordinary temperature stability and heating rear stability situation by the product prepared respectively in embodiment and comparative example, wherein estimation of stability standard is shown in Table 1, and table 2 is score value.Liquid situation processes as follows: response time and temperature divide six groups of 60 DEG C/30min, 65 DEG C/30min, 70 DEG C/5min, 75 DEG C/5min, 80 DEG C/2min, 85 DEG C/2min.Observe the situation after its heating.Wherein heated liquid situation is as shown in table 3.Stability standards of grading such as table 1, score value height person is more stable.
Table 1 suspension type liquid fertilizer stability assessment standard
Wherein, the liquidity scale is observe the suspending stabilized situation of product in its suspension time, and obvious flowing and "None" does not occur in product, and product occurs that a small amount of flowing is i.e. " lacking ".
Product scoring situation in table 2 embodiment and comparative example
Situation after the heating of table 3 suspension type liquid fertilizer
Note: "-" represents that suspension type liquid fertilizer appearance is not any change, " trace " represents generation trace floccule.
From table 2, comparative example 1 with in 2 owing to calcium ion concentration is different from the present invention with stabilizer, its suspension time and suspension stability scoring are relatively low, and substantially relatively the present invention is poor for above-mentioned performance.Showing from table 3 result, along with the rising of heating-up temperature, liquid calcium fertilizer thermal instability is also being stepped up, by trace floccule or floccule occur to until there is solidification.Especially in comparative example 1, calcium ion addition is too high, even 60 DEG C of K cryogenic treatment, liquid calcium fertilizer also begins to produce obvious floccule, and 65 DEG C of process occur as soon as solidification, and heating-up temperature continues to raise, and solidification phenomenon can be more serious.It addition, owing to stabilizer is sodium carboxymethyl cellulose in comparative example 2, its heat stability is not so good as xanthan gum, namely creates floccule under 60 DEG C of K cryogenic treatment.In sum, suspension liquid fertilizer not only suspension time provided by the invention is long, and suspension character is good, and can also keep good stability after the heating, possesses fabulous application prospect.
