Test means for dispersion properties of hydroxypropyl methylcellulose

In order to understand the true dispersion outcome of your dispersant and look at the dispersant qualitatively, the indifference check of the dispersant is often conducted inside the aqueous solution of the dispersant with chlorinated hydrocarbons like monochlorethylene or dichloroethane, which are similar to vinyl fabric chloride.

1. Analyze raw supplies and equipment:

1. Raw substance dichlorethylene or dichloroethane evaluation natural distilled h2o dispersant test 2. Devices shuttle shaker F7.-2 sort volumetric flask 500ml colorimetric hose 50ml 2. Check procedure:

1. Weigh .05g (exact to .002g) of the dispersant in a beaker. Following it really is dissolved, include it with a 500ml volumetric flask. Rinse off the beaker with h2o until it actually gets to the symbol in the volumetric flask. Dig it evenly and set up besides.

2. Add more 17ml trichlorethylene or methylene chloride on the 50ml colorimetric hose, then put the dissolved dispersant (test) aqueous strategy to 50ml, put it in the shaker, shake for one minute, remove it, see the stratification rate and record this type of water.

3. Examination results

1. Small the particle scale of the oils droplets, the more effective the dispersion potential, and the other way round.

2. The greater the steadiness of the essential oil beads (reduced demulsification), the more robust the stick preservation potential, and viceversa.
