Weigh the crucible and record the value as M1，Take 2g of test samples in the crucible (correct to 0.0001g) And record the value as M2，put the testsamplesin the oven at 105℃ for 3h, cool in a dryer to room temperature, weigh and record the value as M3, put the testsamplesinto the muffle furnace and burn at 450℃ for 3h, cool in a dryer to room temperature，weigh and record the value as M4.

Put the beaker on the scale and make zero, Take 2g of test samples in the beaker(correct to 0.01g) , add 198g of water at about 90 ° C. Stir quickly with a glass rod，make it dispersed uniformly，Then put the beaker in basin with ice water, Stir and move from fast to slow to preventsplashing. When the water cool to room temperature, take out the beaker and dry the surface, putit onthe scale thathasbeenzeroed, according to the actual mass of the sample, add water to a 2% solution (High temperatures make water evaporate quickly, and will reduce the quality of water). Then put the beaker in basin with ice water for about 20 minutes, make it dissolved fully, then take the solution out of the beaker into thermostat water bath to 20℃±0.1℃, measure with the Brookfield viscometer (2% HPMC Solution,Spindle:No.7,rotate speed:20RPS).
