The role of iron oxide yellow

Iron oxide yellow protective cover a variety of colors,yellow iron oxide pigments for a variety of paints and protective coloring substances,including water-based exterior paints,powder coatings,etc.;are also applicable to oil paint,including oxygen,alkyd,amino,etc.variousprimers and topcoats;paint can also be used in toys,decorative paint,furniture paint,lacquer and enamel electrophoresis after surface application of these articles of iron oxide yellow,the color is not easy to retire,increasing the degree of brilliant hues.

In recent years,technology experts yellow iron oxide prepared by changing the seed crystal,instead of using part of the conventionally used Na2CO3 solution of NaOH to precipitate ferrous sulfate,and passed through aseed prepared air oxidation;Zn2 + salt and adding a small amount of nucleating structure modulating agent to change its nucleus particle morphology,to buy low water,high-density characteristics.Yellow iron oxide preparation process evolved into a bargain-hunting quantity of heavy iron oxideyellow pigments.

Experts have developed an ultra-fine iron oxide yellow craftsmanship,first with a wet sulfate method of producing iron oxide yellow,iron oxide yellow and then crushing and coarse grinding whirlwind two-step formation of ultra-fine iron oxide yellow,iron oxide yellow by the number of coarse crushed in 8-12 mesh;characterized in that:the cyclone mill speed is 2000 rev/min,driven by its raw speed of 120-130 m/sec high-speed operation;the cyclone when high speed grinding,grinding aids in the starting solution of the percentage by weight of 0.5%-5%.This process not only makes HEGMAN particularly high fineness yellow iron oxide paste,while increasing the yellow iron oxide pigment hiding power and tinting strength.
