4 Principle
The high temperature dilute group type and non-diluted type Wumin station are used. The design is implemented in EC 3. The solvent and the flow time are calculated from the flow time and the melting point. The viscosity and characteristic condensation are calculated. 5 Reagents and materials

7 Operation steps
7.1 Method 4 Non-diluted sound temperature zone viscosity 7.1.1 Determination of the total viscosity of the mixed agent 7.1.1.: At 2", 3 = kidney connected to the meter, insert the polytetrafluoroethylene tube from the tube to the bottom of the A-shaped protrusion, and place the meter vertical hill in the water surface 5cm above the water surface. 7. 1.1.2 Through the filtered phase in the tube, add about 0.3% of the solution (with a secretion rate of 1.3%) into the micro-tube (see Appendix A2 of G16$2-1953).
HG/T36051999
7., 1.3 Use the latex tube on the tube tightly, and change the mL or 1.5 mL syringe, and finally change the dry rubber tube to put the mixed solution into the pool and bubble it with the pressure ball once, and heat it for 10 minutes. At the same time, wait for the bubbles to disappear. 7.1.1.4 Use a 50 to 20mL needle: 2.5 pieces of latex bite to slowly push the mixed solvent into the C ball: when the liquid rises to about half of the 1 ball, stop pumping. Suck the needle and release the latex tube on 3*, let the micro-body fall from the bottom: when the speed surface drops to the scale line, start the sand speed, and the scale line State, time, the sand table is: record the flow through time: 7..1.5 more minutes 7.1.1.4 step plan, measure twice, each flow through time difference shall not exceed .2, take the technical average, recorded as 1e7.1.1.6 reverse the flow through the case of ethylene oxide pipe water effect tour guide specification, 7.1.2 polyoxyethylene energy shrink wave preparation
7.1.2.1 Weigh the test standard). 0003 Pour into a 25m. storage bottle and store at 50°C. Use 1 times the pressure to make the pipe absorption rate: bZxz.net
Note: When the maintenance effect is maintained at one point, the preparation method should be full of 1.5, but it must be between 1.2--2. 7.1.2.2 Place the standard sample in a 120°C glycerol bath and continue to dissolve for 30 min. After it is completely dissolved, transfer it to a 50°C constant temperature container and add the thermostatically controlled mixture to the mark. Take it out and call the thermostatic container for later use. 7.1.3 Determination of the flow-through time of ether solution 7.1.3.1 Place about 11 ml of polyol in a cage and place it in a viscometer. The liquid is sucked and pressed through the sieve of the fluorine film for the first time, and the concentrated liquid is sent to the state and the residual liquid is boiled with water. 7.1.3.2 The remaining about 15ml is added to the oxygen and the viscosity is measured in the cover of 7.1.1.3~7.-.1.5. The flow time is measured twice, and the value of each flow time shall not exceed (.2. The arithmetic average is taken as the value, recorded as 1. 7.1.3.3 has six portions of the same concentration. According to the provisions of 7.1.3. and 7.1.3.2, the new liquid is driven every day. 7. 2 Method 7.2.1 Prepare chlorine solution by weighing the sample to be tested and heating it with a 2-well scale. Add 150ml of chlorine solution and heat it in 120ml oil. Stir occasionally. After the sample is completely dissolved, transfer it to a constant temperature and humidity chamber for 10 minutes. Add the solution to the solution until it is fully dissolved. Take out the solution and filter it into a 25ml glass bottle with a 50ml filter paper. 7.2.2 Dry the sample. 2.2.1 From 7.1.1.1 to 7.1.1.5, measure the mixed flux flow rate in 7.2.2.2 for 10 ml. Measure the oxygen formaldehyde rate according to 7-1.3.2. Pipette the mixed flux into the 50°C storage tube and add 1 ml of the mixed flux to the tube. Pour the mixed flux into the tube with a needle. Read the mixture in the tube according to 7.13.2.2.1 Test case chlorine flow through the closed bay according to 2.2.3, with 6V home agent storage tube and then transferred to 51.1C:1. and 10mL mud platform agent, the five points of concentration of 1, 48, and 8.1 viscosity number
