    Hello dear dear, the advantages of the Minchi Qiba dye. Soluble in organic solvents, it has good comprehensive color fastness properties. In particular, it has good solubility in alcohols, ketones and esters, and is basically insoluble or rarely soluble in alkanes, and is widely used in coatings.

    Good light fastness. The practical application of Ciba dyes to replace ordinary reactive dyes, among which the red H, yellow HW and navy blue H-2G dyes of Ciba have the characteristics of good dyefastness, high color yield of medium and dark dyeing, and show excellent performance ratio. The gap between domestic dyes and imported dyes and the reasons for the gap There are still several outstanding problems in domestic dyes

    First, the stability is poor - the difference between batches is relatively large; Second, the force is low - although the first is low, the amount of domestic dyes in the use process is relatively large; Third, the chromatogram is incomplete, especially the bright color dyes, which need to be further strengthened. At the same time, on the quality of domestic dyes and imported dyes, the former personnel of dye enterprises expressed their views based on their own experience and practice. First, there is a gap in products, a person in charge of a plastic dyeing enterprise in Chongqing said, "To put it simply, compared with imported dyes, there are generally two aspects of 'big gap'.

    First, the gap is relatively large, and individual imported products are even twice or more than domestic products. Second, the quality gap is relatively large. An obvious fact is that at present, for many plastic dyeing enterprises, if the performance requirements of the product in terms of color fastness and vividness are not high, they will choose to use domestic products; If the requirements are relatively high, imported products will still be used.

    Most dye workers believe that the gap between domestic dye products and imported products is mainly manifested in four aspects: 1. Poor stability, large product performance gap between batches, and poor dyeing reproducibility; 2. The force is not high, and the amount of dye is large; 3. The particle size is uneven, and the dyeing effect is not good; 4. The chromatogram of some dye varieties is not wide enough and needs to be further broadened. These parameters play a decisive role in the effectiveness of the staining.

    Compared with domestic dyes, imported dyes are relatively high, which is caused by their high performance and high added value. In addition to the gaps in these products themselves, there are also some other problems that are common to domestic enterprises. For example, in terms of pre-sales and after-sales service, there is still a gap between domestic enterprises and large multinational enterprises.

    Many companies are only making products and do not use such additional services as sales content, which also hinders the creation of corporate brands.
