43 Determination of carbon monoxide content
The sand is wet tested at a rate of 1S1-200. 1.4 Determination of tensile strength
1.4.1 Determination of electrostatic diaphragm
Take an appropriate amount of the sample and micro-break it into powder. Mix it with ethanol in a vacuum and precipitate it at a power of 25°. After ultracentrifugation for 3 minutes, connect it to a stainless steel + thin film and place it on a microscope. , at a magnification of 100,000, use a camera to make an electron micrograph of the sample, use a meter mark on the photograph to measure or measure at least 1 new long diameter of each bottle [computer software can be used for statistical processing), calculate the average value: Average particle diameter (um) is calculated as follows:
Wuzhong:
The long diameter of the sample, the unit is meter m:
Micro short diameter, the unit is nanometer (nm): Measure the microscopic effect,
4.4.2 Determination of the average particle size of the product by X-ray diffractometer: The sample is subjected to X-ray diffractometer measurement, the angle of the angle is 25°-35°; Use pure potassium hydride to measure the sample according to the conditions, and the half-width of the peak at 28.1 is determined by the half-width of the peak at the same time. The peak of the internal emission peak at 29.3 of the product is taken, and the average particle size is calculated by Scherrer formula: 4.5 Determination of specific surface area
Divide the G and determine the specific surface area. According to the method specified in 32822: 4.6 Determination of cluster index
Combine about 0.C5g of micro calcium carbonate and fry it in 50mL of calcined ring. Tin (2--3) 20/1 milliliter of sodium beer fraction, use 0--20 water to calibrate the moisture content of the separation cable) Report the light receiving (disk specification: 0.21-122m required to complete the body and half-average new diameter; use 1.4.3 strips to get the average product material as the first flat piece particle size to calculate the cluster index: according to the actual (2 calculation:
micro-light particle size analysis to get the average value of the case particles, the unit is nanometers (): 2

The inspection rate is less than 5.1.2. The main content or, the ratio of the table before rent, the profit, the self-measurement, the moisture. PH state salt does not fall into the zero flow standard inspection item F, the batch inspection should be: 5.2 The length of each batch of production shall not exceed 60.
5.3 According to the current determination of (13/7 The sampling number should be: when sampling, lift the white fruit sampler up to 34 points of the material layer, and collect the sample with a rod. After the sample is collected, the sample should be collected at least 2 points. At this time, the sample will be marked with the manufacturer's name, product name, grade, sample number, date and bottle number on the inspection column, and three other samples should be kept for later use. The manufacturer shall print the sample on the packaging line or the color sample can be automatically collected before the sample is loaded. The quality control department of the manufacturer shall conduct thermal inspection according to the standard. The manufacturer guarantees that all the ultrafine carbon calcium products shipped from the factory meet the requirements of this standard: 5.5 The user has the right to accept the ultrafine carbon calcium products received in accordance with the provisions of this standard and to conduct verification within two months from the date of arrival. 5.5 If any of the inspection results do not meet the requirements of this standard, the product must be re-sampled or re-packed. If any of the inspection results do not meet the requirements of this standard, the entire batch of products shall be deemed non-conforming. 5.
