Butyl silica gel.
5.5.2 Working procedure
Put the color changing agent in an oven at 120℃, then cool to room temperature and take about 2-3 samples (accurate weighing 0.0002%) from a pre-weighted grid, so that the sample thickness does not exceed 1. Then put the bottle and the cover in a dryer for 4 hours, and cover the cover when taking it out, and weigh it repeatedly until the sample is fixed.
The test pressure is calculated by the following formula (A), A()
,-drying tip, dead
, the bottle of the sample and the weighing bottle, more, the sample and the weighing bottle are directly heated, more, W-the amount of the sample: more.
The allowable difference of the parallel test results is 1.2%. 6 Inspection period
6.】The number of finished products of Xianglantai should be inspected by the inspection department of the manufacturer to ensure that the products leaving the factory meet the original standards and sign. Each batch is out! All products should have quality certificates: Contents include: manufacturer, product name, trademark, production date (batch number, net number, product quality certificate and this standard. 6.2 The inspection unit has the right to inspect the received products according to the provisions of this standard to see if they meet the requirements of this standard. The batch number is used for acceptance, and different batch numbers are inspected separately: 6.3 For each batch of packaging units, one sample is selected for testing if it is less than 1%, and samples are selected for testing if it is more than 100. Use a sampler to evenly distribute the samples from each packaging unit. Take 30-100 samples of oil, and put all the collected samples into the sample collection for research and analysis. Take 5-100 samples and put them into two bottles with different differences. The name of the product, batch number, and the date of collection shall be marked. One bottle shall be used for inspection and stored for future reference. .4 If one of the indicators in the acceptance results does not meet the requirements, the manufacturer may add a new sample for re-inspection together with the manufacturer. If one of the indicators still fails to meet the requirements after the overall results, the batch of products shall be deemed unqualified. -- 13 --

6.5 When the supplier has any disagreement with the product quality, the two parties can negotiate to resolve the issue or invite a statutory inspection agency to make an arbitration, and the cost shall be borne by the supplier. bzxz.net
6.B Color, aroma, tower temperature, solubility are factory inspection indicators. Drying loss is a type inspection indicator and shall be tested every time.
Marking, packaging, transportation, inspection, storage
7.1 The supply of ethylene should be packaged in a large-mouthed zinc-sensitive iron drum sealed with ethylene. Cardboard or tinplate, polyethylene bag should be tightly sealed. The outside of the package should be marked with: manufacturer name, product name, standard, batch number, recycling, date of publication and this standard deviation. If the ordering unit has special requirements, it can be coordinated with the manufacturer. 7.2 Ethyl vanillin should be stored in a dry and ventilated warehouse to avoid contamination by foreign air. During transportation, it should be lightly packed and transported to prevent sun exposure and contamination.
7.3 Under the condition of meeting the specified storage conditions, packaging quality and technical requirements, the shelf life of this product is one year. .- 4
