Glass Cup Testing Method
This standard is used for glass materials containing reduced pressure. Determination of physical and chemical properties
1.1 Determination of heat shock resistance
The sample is placed in cold water at 1t~-5℃ for smi and then taken out for water filtration and oil test. 1.2 Determination of water resistance 1.2.1 Sample preparation QB/T3561-1999 ZB/TY22004—1986 Obtain several test cups, wash them with water, rinse them three times with steamed water and then dry them. After the sample cups are crushed, 30-50g of monochrome films with a thickness greater than 1.5mm are selected and put into a grinding mill. Use a standard paper with an aperture of 0.5mm and a margin of 0.3mm to screen out films with a size greater than 0.3mm and less than 0.5 mm. Place the screened films on a clean paper, use a magnet to move them back and forth and remove iron filings, until no iron is found. Put the sample in a dry place, wash it with anhydrous ethyl acetate for 6 times, then dry it in an oven at 110°C for half an hour, and place it in a desiccator for cold sweeping for later use.
1.2.2 Determination steps
Weigh the treated sample and add 2.00:1 into a 5 mL sample bottle. Rinse the sample on the bottom of the bottle with steam. Add steamed water to the scale line. Take another 5 mL sample bottle that has been treated, add steamed water to the scale line, and do a vacuum test. Submerge the four bottles in a (98 ± 1) ℃ hot water bath until the bottle is halfway through the bottle. Recover the temperature within (9 ± 1) ℃, then cover the bottle and cool it for 1 hour. Take out the bottle, uncork it, and cool it to half of the water bath. After cooling to room temperature, adjust the temperature to the scale line with steamed water and put the cork on it. After mixing well, let it stand for 5 minutes to allow the sample to sink and obtain the upper liquid. Use a pipette to draw 25 ml of the upper clear liquid from the three containers into three triangular containers respectively, and add 2 drops of 0.25 N benzoic acid solution to each container: add 0.01 N benzoic acid standard to filter the filter until it turns slightly red, and record the number of liters of 0.01 N benzoic acid standard solution used, and take the average value as V. Use the same method to do the short-circuit test, and calculate the number of liters of 0.01 N benzoic acid standard used:
formula:
Na,0 (mg/g)(-F)xNx0.031x10002x2
= 0.031×(FF) N ×1000
V—Sample consumes 0.01N standard solution of aldehyde regularly: Blank consumes 0.01mL standard solution of acid regularly: N—Concentration of hydrochloric acid standard solution:
0.031Na,O when the sample is tested
Note 1, if the sample is tested with acid, it will not be recognized. Approved by the State Bureau of Light Industry on April 21, 1999

Note 2, there is a problem that the water resistance of the sample is hidden. The product should be pre-treated in three negative flasks before use, that is, the sample should be selected in a half-filled container. Repeat the water test for several times, and then measure the blank test value for three times. Select the volumetric bottle with outstanding performance for special use. Use two bottles of water or two steamed water bottles for the test. The volumetric bottle must not be directly exposed to hot water and must be placed on a shelf with a support. Note 5: The standard screen mesh is made of stainless steel with a hole range of n3 mm and 0.5 mm. It can be 0.28 mm and n.45 mm. Stress measurement First, control the stress meter and check the interference color purple-red as the rate point. Then put the sample into the field of view, rotate the sample, and observe the ring in the center direction until the interference color image with full brightness is seen in the field of view. Observe the interference color and find out the optical path difference.
Compare the color and optical path difference.
T||Specifications, dimensions and capacity
Measurement of optical path difference 2.1 Measure the height of the filling with a ruler, and the distance from the bottom of the cup to the part of the filling is the standard. 2.2 Measure the outer diameter of the cup with a vernier ruler: the measuring part is based on the flat diameter of the cup mouth (12.3 Measure the outer diameter of the cup bottom with a standard caliper, and the measuring part is based on the average diameter of the bottom plane (Figure 1). 2.4 Measure the thickness of the cup mouth with a thickness ruler 10mm below the mouth (Figure 2). bzxZ.net
2.5 Measure the thickness of the filling bottom with a vernier caliper, and extend the vernier caliper directly into the inside of the cup to the bottom. Note the reading and then mark it. Measure the height of the cup body with a caliper and write down the integer. The difference between the two readings is the height of the concave part of the test part, and the height is measured with a 2.6° angle ruler. The sample to be measured is placed on the original plane, and the half of the side of the angle is multiplied by the angle, and the sample center is placed on the same plane. At the same time, the maximum and minimum values ​​on the other side of the mouth are measured, and the difference between the two is the height and deflection of the cup body (Figure 3).
2. Capacity determination
Use a measuring tube to measure the capacity of the sample water in the room, record the number, then fill the selected cup, record the reading of the remaining water in the tube, and the difference between the two readings is the value of the measured cup: 2. Determination of the dripping head at the mouth of the cup B
Place the depth scale of the vernier caliper parallel to the mark on a horizontal plane, move the vernier caliper so that its end is at the highest point of the dripping head of any mouth, measure a number A, and then fill the cup 10mm away from both sides of the dripping head. Repeat the above probes at this edge, and get two readings, take the lower one, and the difference between A and B is the height of the full head. (See closing 4) ml

3 Appearance quality inspection
QH/T 35611999
The distance between the tested sample and a 40W fluorescent lamp shall not be less than 500m, and the visual inspection shall prevail. If the defect is small and accurate, it can be determined by placing a person to check for bubbles, impurities, streaks and other defects (Figure 5). If it is still uncertain, the actual sample can be sealed for comparison. Figure 5
