Foreword
GB/T 10209 "monoammonium phosphate, diammonium phosphate determination method" is divided into four parts.
--- Part 1. total nitrogen content;
--- Part 2. phosphorus content;
--- Part 3. Water;
--- Part 4. granularity.
This section is GB/T Part of 410,209.
This Part replaces GB/T 10209.4-2001 "monoammonium phosphate, diammonium phosphate particle size determination."
The main difference between this version and the previous version is. according to the new requirements of the standard format has been rewritten.
This part is proposed by the China Petroleum and Chemical Industry Association.
This part of the National Standardization Technical Committee and soil conditioners Fertilizers (SAC/TC105) centralized.
This section drafted by. National Fertilizer Quality Supervision and Inspection Center (Shanghai), Liuguo Chemical Corporation.
The main drafters of this section. Zhou Yongming, yellow front, business according to Cong Mu Yongfeng, Yang.
This section first published in 1988 (GB/T 10211-1988), 2001 on the first amendment.
MAP, DAP measurement method
Part 4. size
1 Scope
This section provides GB/T 10209.4 measured by sieving granular monoammonium phosphate, diammonium phosphate particle size.
This section applies to a variety of granular MAP production process, diammonium phosphate particle size measurement.

GB/T 6003.1-1997 woven wire mesh test sieve (eqv ISO 3310-1.1990)
Principle 3
By sieving granular monoammonium phosphate, diammonium phosphate into different particle diameters, weighing, calculate the mass fraction.
4 Instrument
4.1 laboratory equipment generally;
4.2 Balance. a sense of the amount of 0.5g;
4.3 test sieve (GB/T 6003.1-1997R40/3 series). a pore diameter of 1.00mm, 4.00mm sieve set, with cover and sieve
Chassis;
4.4 sieve shaker.
5 Steps
By 1.00mm and 4.00mm sieve apertures sequentially folded by the first, laboratory sample weighed about 200g, accurate to 0.5g,
Pore \u200b\u200bsize is placed on the 4.00mm sieve, sieve cover lid placed on the sieve shaker, clamping, vibration 5min, the chassis and 4.00mm aperture sieve
Weighing on the sample, caught in the meshes of the particles does not pass through the sieve meter.
NOTE. If there is no vibration sieve, vibrating sieve can be used manually, but using a sieve shaker arbitration.
6 expression analysis
Size (w), to a particle size 1.00mm ~ 4.00mm particulate quality of the sample mass fraction, expressed in%, according to equation (1)
Calculated.
w = m1-m2m1 ×
100 (1)
Where.
Value m1 --- sample mass, in grams (g);
m2 --- 4.00mm aperture sieve and sample the quality of the chassis and, in grams (g).
Calculation result to one decimal place.
