Observe with naked eyes under natural light.
4.3.2 Moisture
4.3.2.1 Use a weighing bottle that has been dried at 105±3℃ to weigh 1~~2g of the sample (accurate to 0.0001g), place the weighing bottle with the sample in an oven at 105±3℃, dry for 2h, take out the weighing bottle, place it in a desiccator, cool it to room temperature (not less than 50min), and weigh it.

4.3.3 Water-insoluble matter
4.3.3.1 Take 0.2-0.3g of absorbent cotton and put it into a roll made of lens paper, put it into a weighing bottle and dry it at 105±3°C until constant weight for later use.
4.3.3.2 Take 0.5±0.1 of the sample, put it into the above paper roll, wrap it tightly, and weigh it together with the weighing bottle (weighing to 0.0001g), then put the paper roll into the sample cup of the extractor, and hang the sample cup under the micro condenser of the extractor. 4.3.3.3 Pour 250~300ml of distilled water into the extractor, put the extractor into the electric heating jacket to heat and keep it boiling, and extract until the effluent in the sample cup is colorless (about 3h). Take out the paper and put it into the weighing bottle, put it in an oven at 105±3°C for 2h, then take out the weighing bottle and put it in a desiccator, cool it to room temperature (not less than 30min), and weigh it. 4.3,3.4 Calculation

Weigh 0.3g of sample and place it in a 50ml beaker, add 30ml of distilled water, and stir with a magnetic stirrer at room temperature for 1h to dissolve. Measure the pH value of the solution with a pH meter.
4,3.5 Drilling fluid performance test method
4.3.5.1 Preparation of wood pulp
In a sample cup containing 350ml of distilled water, add 225g of sodium swellable solid for drilling fluid test, stir at high speed for 20min, interrupt at least twice to scrape off the sample adhering to the cup wall, and seal and cure at room temperature for 24h as base slurry. 4.3.5.2 Fresh water drilling fluid performance test
a, add 10.5g of SPNH to the base slurry, stir at high speed for 20min, interrupt twice to scrape off the sample adhering to the cup wall. b, transfer the above slurry into a high temperature furnace and heat it at 180°C for 16h. C. Take out the high temperature tank, cool and open it, and measure the apparent viscosity at 24±3°C, the room temperature medium pressure (24±3\C/690kPa) filtration loss and the high temperature and high pressure (150°C/3450kPa) filtration loss according to the method of ZB/TE13004-90. 4.3.5.3150g/1 Sodium chloride contaminated drilling fluid performance test a. Add 17.5g SPNH to the base slurry and stir at high speed for 20min. During the process, it should be interrupted twice to remove the product adhering to the wall of the cup. Then add 52.5g sodium chloride and stir at high speed for 10min. Add 2ml of 20% sodium oxide solution to adjust the pH. b. Follow the steps b and c in 4,3.5,2. The numerical rounding in 4,3,6 shall be carried out according to GB8176 "Numerical Rounding Rules". 4,3,7 Test report

5.1 The product shall be inspected by the quality inspection department of the manufacturer. The manufacturer shall ensure that all products leaving the factory meet the requirements of this standard. 5.2 The manufacturer shall divide the daily output into batches, and the delivery batches shall be divided into batches, with the maximum batch not exceeding 40t. 5.3 Sampling method
SY/T5679-93
5.3.1 The sampling points of bagged SPNH shall be determined on the side in a cross shape according to the stacking height, shape and quantity. Each batch shall not be less than 15 points.
5.3.2 Use a metal sampler to take samples at different depths of the package. The total sampling shall not be less than 500g. The sample shall be mixed and evenly divided into two parts by quartering method, and respectively put into clean, dry ground-mouth bottles, and indicate the product name or code, batch number, production period, sampling date, sampler, manufacturer name, etc. One bottle shall be sent for inspection, and one bottle shall be kept for reference. 5.4 If the inspection fails to meet the standard requirements, samples should be taken from the packaging of the two batches for re-inspection. If the re-inspection still fails, the batch of products is unqualified.
5.5 The user unit has the right to inspect the products according to the standards, and the sampling and acceptance work should be completed within the period specified in the contract. 6 When the supply and demand parties have objections to the product quality, the two parties shall negotiate. 6 Packaging, marking and quality inspection form
6.1 Packaging
The packaging bag of SPNH should have sufficient strength and should have at least two layers. The outer layer is a three-in-one paper-plastic composite packaging with a plastic lining. The net weight of each bag is 25kg, and the allowable error is ±2%. For each batch of products, 40 bags are inspected, and the average value should be no less than 25kg. 6.2 Marking
The following content should be printed on the outside of the packaging bag: registered trademark, product name, code, net weight, quality level, batch number, date of manufacture, and manufacturer.
