The main test items stipulated in GB/T 6144-2010 "Synthetic cutting fluid" are:1. Appearance detection index requirementsLiquid cutting fluid requirements: no stratification, no precipitation, uniform liquid concentrationPaste cutting fluid requirements: no different phase precipitation, uniform pas

There are many kinds of steel, mechanical engineering commonly used steel including:carbon steel (including low carbon steel, medium carbon steel and high carbon steel),alloy steel, easy cutting steel and so on. Generally speaking, the machinability of steel is better. Because of the different prope

First, cooling effectThe cooling effect relies on the convection heat transfer and vaporization of the cutting fluid to remove the cutting heat from the solid (tool, workpiece and chip), reduce the temperature of the cutting zone, reduce workpiece deformation, and maintain the hardness and size of t

Glycerol, the chemical name of glycerol, is very absorbent. Due to its appearance as a clear and viscous liquid, many people mistake it for an oil. In fact, glycerol is an alcohol, a substance that is relatively close to alcohol. Glycerin absorbs quickly, it is the best product for replenishing seas

Propylene glycol:1, 2-propylene glycol is a chemical reagent, miscible with water, ethanol and a variety of organic solvents. Propylene glycol can be used as the raw material of unsaturated polyester resin. It can be used as a wetting agent in combination with glycerin or sorbitol in cosmetics, toot

Refined glycerin is generally referred to as cosmetic grade 99.5% glycerin, which is USP grade glycerin.General glycerin refers to 95 concentration glycerin, generally used in industry, can not be used in cosmetics and drugs and food industry, of course, refined glycerin can also be used as food gra

Through the modification experiment of glycerol, modified glycerol was obtained and then combined with sodium dodecyl sulfonate to get slag complex grinding aid. Through the experiment, it was found that the molar ratio of N2-N- to formic acid is 1:1.4, the dosage of sulfuric acid is 0.30%, the reac

This product is the condensation of advanced fatty alcohol and ethylene oxide, milky paste, easy to dissolve in water, has excellent dyeing, diffusion, penetration, emulsification, wettability. It is used as levelling agent, leveling agent and blocking agent in textile printing and dyeing. It is use

Polyethylene glycol series products can be used in pharmaceutical. Polyethylene glycol with low relative molecular weight can be used as solvent, cosolvent, dispersant, o/w emulsifier and stabilizer for the production of cement suspension, emulsion, injection, etc., and also used as water-soluble o
