A.1 Sample collection and processing
Appendix A
(Normative Appendix)
Determination of the quality of the sample
The sample collection and processing shall be carried out in accordance with GB/T4S0 and GB/T10739 A.2 Instruments
Paper cutter and ruler.
A.2.2 Magnetic: 0.01g
Oven: able to maintain humidity at 1052) A.2.3
Oil: able to make 10 square porcelain plates.
Aluminum acid: chemical group.
T-tip.
Rubber yoke.
Porcelain (or stainless steel) plate: 150mm×600mm. A.3 Test steps
Accurately take 10~20 samples of 100mx100mm (allowable deviation is ±0.5mm), and randomly select four For the determination of the sample,
A.3.2 Place the sample in an oven at (15+2)℃ for 1 hour to dry until the sample bottle is dry. A.3.3 Carefully place the test paper after constant weight into the pool of acid at a temperature of (30±5)℃. After there is no white spot on the paper, take it out for testing after 5 minutes. Used to gently control the oil removal, press on the upper and lower layers of the sample at a distance of 10 layers, put it in the contact paper (or in a good place), and add rubber to absorb the floating oil. Each time the air is tested for 1min2min, and the upper and lower absorbent paper in contact with the sample should be replaced after each pressing. Press quickly and repeatedly until there is no trace of movement on the absorbent paper: if After repeatedly applying pressure 4 to 5 times, press again for 1 to 3 times. If the difference between the results before and after is within (1 mm), it is considered that there is no oil mark on the surface of the oil sample. Then quickly weigh the oil content in the measuring section. A.3.4 The oil content in the measuring section is not less than 20: A.4 Calculation of results
Follow the formula g (A.1 Calculation, let the total result be 1/m=(p)A
One piece of oil absorption, the unit is grams per square meter (/m): : The total mass of the four test pieces after absorption, the unit is grams (g): 25. When the sample surface area is 0.01m).
