This paper has predicted indirectly by means of measuring the equivalent viscosity of resorcin-formaldehyde resin liquor(thereinafter referred to as RF resin).
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 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.
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 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.
Abstract: When water glass seriflux as chemistry injection material, its kinetic viscosity is varying with time, so the process of seriflux permeating in the sand is complicated.
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.
