Pigment dye detection

Basic introduction

A powdery substance used to pigment. It does not dissolve in water, grease, resin, organic solvents and other media, but can disperse evenly in these media and make the media color, and it has a certain hiding power.
Dyes are colored substances. But colored substances are not necessarily dyes. As a dye, it is necessary to be able to attach a certain color to the fiber. And it is not easy to fall off and discolor.

Testing products

Pigment filler:
Titanium dioxide, titanium dioxide, Lide powder, chromium oxide, phthalocyanine green, lead chrome yellow, pigment carbon black, mica powder, cadmium red pigment, ceramic pigment, acrylic pigment, gouache pigment, organic pigment, inorganic pigment, chemical pigment, plastic Pigments, iron oxide pigments, wall painting pigments, hand-painted wall pigments, etc.
dye:
Disperse dyes, acid dyes, basic dyes, sulfur dyes, reactive dyes, cationic dyes, neutral dyes, vat dyes, direct dye oxidation dyes, polycondensation dyes, ice dyes, chemical dyes, natural dyes, oil dyes, metal chromium Dyes, solvent dyes, vegetable dyes, etc.

Test items

Physical properties: appearance, transparency, color, adhesion, pH value, flash point, density, viscosity, fineness, ash, moisture, specific volume, composition analysis, volume solid content, iron oxide test, etc .;
Chemical properties: water resistance, acid and alkali resistance, corrosion resistance, abrasion resistance, weather resistance;
Construction performance: consumption, oil absorption, paint film abrasiveness, leveling, hiding power, sagging, usage, paint film thickness (wet film thickness, dry film thickness), drying time (surface dry, hard dry), etc. ;
Aging test: salt fog aging, high and low temperature cycling, light aging, ozone aging, artificial accelerated aging and other aging projects;
Harmful substances: VOC, benzene content, toluene, ethylbenzene, xylene total, free formaldehyde content, total TDI and HDI content, glycol ether, heavy metal content (lead, mercury, chromium, cadmium, etc.).
