What is azo test report?

Yes, it is mainly about the report of whether the dye of the cloth contains azo or not. At present, environmental protection dyes are basically used in China, and there is no problem of azo content.

The azo test, very simply, is mainly for dye coatings. It's very cheap, I'll line up first and wait for the landlord to contact.

It is to ask you to do a test for whether it contains azo dyes and report to him. Of course, the report cannot show the presence of azo, which is an environmentally prohibited substance.

AZO azo compounds are compounds formed by the attachment of azo group-n=n- to two hydrocarbon groups, and its general formula is r-n=n-r. The nouns related to azo azo compounds in life are: azo free, azo free certificate, azo free test, azo fuel, azo dye, etc.

The materials involved in azo synthesis mainly include: cloth, leather, paint, plastic, rubber, colorants, etc.

In the process of production, storage, transportation and use, when textiles of different colors are stacked on top of each other and in close contact, the color migration phenomenon may occur between adjacent fabrics or the same fabric, thus affecting the inherent color of textiles.

Therefore, it is necessary to carry out a color migration test on textiles.

Azo compound test.

AZO azo free is a compound formed by linking azo group-N=N- with two hydrocarbon groups, and its general formula is R-N=azo compound: plastics, rubber, colorants, cloth, leather, paint, etc.

The testing process is generally divided into: consulting the applicant to provide product information ** and description, ** According to the information provided by the applicant, the technical engineer will make an assessment, determine the items to be tested, and submit ** to the applicant**, the applicant accepts**, the applicant fills in the test application form and submits the test sample together, sample testing - the test will be carried out in accordance with the applicable standards, the laboratory issues a test report, and the laboratory issues a qualified report in accordance with the AZO test.

The AZO test is the decomposable aromatic amine test, the test for dyes; Is cadium a cadmium clerical error? If it is, it may be cadmium-free (CD)-free.

1. Case: The AZO test is a decomposable aromatic amine test, a test for dyes.

2. CADMIUM is cadmium-free (CD) test.

3. Aromatic amine (English: aromatic amine) refers to an amine with an aromatic substituent, that is, -NH2, -NH- or nitrogen-containing groups attached to an aromatic hydrocarbon, and the structure of the aromatic hydrocarbon usually contains one or more benzene rings. Aniline is the simplest example of this type of compound.

Aromatic amines have a high molecular reactivity. Aromatic amines are generally liquids with high boiling points or solids with low melting points, with special odors and high toxicity.

4. Cadmium (gé), English cadmium, derived from kadmia, meaning "earth", was discovered in 1817. It exists in nature with zinc. It is an excellent neutron-absorbing metal, made into rods that slow down the rate of nuclear chain reactions in atomic reactors, and is useful in zinc-cadmium batteries.

Its sulfide is bright in color and is used to make cadmium yellow pigment.
