Dye Industry
Dye refers to a class of organic compounds that can make other substances obtain bright and firm color, because the pigments used now are synthetic, so it is also called synthetic dyes. Dyes and pigments are generally compounds that have their own color and can give other substances a bright and firm color in a molecular or dispersed state.
Dye category:
According to the properties of dyes and application methods, dyes can be classified as follows.
1) According to the state: water-based color paste oily color paste Water-based color essence oily color essence
2) Divided by use: ceramic pigment paint pigment textile pigment plastic pigment
3) By source: natural dyes plant dyes animal dyes synthetic dyes (also known as artificial dyes)
4) According to the properties of dyes and application methods:
Direct dyes insoluble azo dyes Reactive dyes VAT dyes Soluble VAT dyes sulphur dyes Sulphur VAT dyes Phthalocyanine dyes Oxidative dyes polycondensation dyes disperse dyes Acid dyes acid media and acid mordant dyes basic and cationic dyes
Medical Industry
Medical staining refers to the process of using staining techniques in the medical and pharmaceutical fields to observe and diagnose cells, tissues, and drugs.
In the medical field, staining techniques are often used for cytological and histological studies. Through staining, the structure, shape and function of cells and tissues can be more clearly visible, thus helping doctors to diagnose and treat diseases.
Common medical dyeing methods:
1) Conventional staining is one of the most commonly used staining methods, which uses a range of dyes to stain cells and tissues. Common routine staining methods include blood staining, tissue section staining and cell smear staining. These staining methods can help doctors observe the shape, structure and function of cells and tissues to determine if there are abnormalities.
2) Immunohistochemical staining is a method that uses the principle of binding antibodies to specific antigens to stain. By using specific antibodies, specific proteins or molecules in cells and tissues can be flagged, helping doctors determine the type and severity of the disease. Immunohistochemical staining is often used for tumor labeling and immunohistochemistry.
3) Special staining is a special staining method that can be used to observe a specific cell or tissue structure. Common special dyeing methods include silver dyeing, acid dyeing and basic dyeing. These staining methods can help doctors look at specific structures of cells and tissues, such as nerve fibers, bone, and collagen fibers.
