The changes of intrinsic viscosity and end carboxyl group content with temperature and time were studied for poly(trimethylene terephthalate)(PTT), PET and CDP.
Thermogravimetry analysis(TGA) and Dynamic Stress Rheometer(DSR) were used to measure the conversion and viscosity changing with time during the thermopolymerization to form polythioetherimides.
The viscosity increaser of microcrystalline cellulase used in synthetic leather is prepared by using cotton pulp as raw material and waste hydrochloric acid as hydrolyst.
When this product mixtures with other thickner like Guar gum, the viscosity of water solution increases larger or the total content of thickners in water decreases.
The minimum underbalance is independent of viscosity and compressibility and of reservoir fluids.It is a function of the formation porosity, permeability and radius of perforation channels.
Is suitable to the medicine, the date, food, the agricultural chemicals and the special profession, is the ideal pellet pulpous state viscosity fluid fills the equipment.
The results indicated that the nondrying glue made by this way had some advantages, such as excellent non-drying property, strong viscosity, good resistance to water, etc.
This paper has predicted indirectly by means of measuring the equivalent viscosity of resorcin-formaldehyde resin liquor(thereinafter referred to as RF resin).
During the process of converter steelmaking,the oxidbillity of slag had an direct influence on the speed of melting slag,the viscosity of slag and the extent of sputter.
The value of oil absorption, viscosity of Nujol mull, specific surface area, contact angle, distribution of particle size and dispersivity of the calcium carbonate particles were also characterized.
Many factors affecting cell nucle ation and cell growth among the extrusion process such as preshaping pressure, melt temperature, melt viscosity, interfa cial tension,take-up speed and the te...
In the case of laccase, the effect on viscosity and molecular weight of arabinoxylan increased more than of POX, and the effect was more obvious for water unextractable arabinoxylans.
Now, in the water, you need that extra little oomph because the water viscosity slows you down and makes you more stable, it requires a little more force to move around.
At first glance, pitch looks like a solid, but it's not. It's actually a liquid at room temperature—just a very viscous one. Viscosity is a measure of resistance to flow—what we
Some factors that decrease blood flow and increase resistance include increased viscosity of the blood, increased length of the blood vessel and decreased radius of the blood vessel.
And so we have a number of key variables that we control: oxygen content, the light, the light intensity, the dose to cure, the viscosity, the geometry, and we use very sophisticated software to control this process.
