Examples 1 to 4
Each embodiment is using production technology in production system in Fig. 2 and Fig. 3, and the raw material and proportioning that are provided according to following table are given birth to
Produce calcium-replenishing biomass moulding raw material.
The raw material composition that 1 each embodiment of table uses
Note：Quality after the biomass drying of biomass material dry weight system, humate solution dry weight refer to solute humate
Quality；Humate is prepared in raw material, humic acid, NaOH, NH3It is the percentage for deducting and being calculated after moisture, the sum of three
It is 100%；Comparative example is existing cornstalk biological matter raw material.
The physicochemical property of calcium-replenishing biomass moulding raw material made from each embodiment is detected, testing result is shown in Table 2.
Because biological substance shaped granule thermal stability, drop strength and cold intensity test are without country and professional standard, therefore respectively
With reference to《Industrial shaping coal coal heat stability testing method MT/T 924-2004》、《Industrial shaping coal drop strength test method MT/
T925-2004》With《Industrial shaping coal cold pressing strength assay method MT/T 748-2007》Test, analytical test strip part with it is each
Standard is consistent, but when handling heat stability testing data, because biological substance shaped granule diameter itself is less than 13mm, therefore is taken
The grain size measured is denoted as BTS in the ratio of the biological substance shaped granule of 6mm or more+6, other analysis test data processing methods with
Standard is identical.
2 each embodiment of table biological particles Testing index after molding
From table 2 it can be seen that compared with comparative example, the present invention substantially increase biomass moulding raw material thermal stability,
Drop strength and cold compression strength.Embodiment 4 has stronger thermal stability compared with embodiment 2, but humate additive amount is excessive, makes
Production cost rapidly rises.
