腈纶增白剂AD - Introduction
Acrylic fiber brightener AD is a commonly used brightener, its main component is dimethyl phthalate (white crystal powder). It has a strong whitening effect, which can make the acrylic fiber show a brighter white under the white light.
Acrylic brightener AD is widely used in the textile industry, especially in the production of acrylic textiles, which can improve the whiteness of textiles and make fabrics more bright and beautiful. In addition, acrylic brightener AD can also be used in the paper industry and plastic products whitening.
The preparation method of acrylic fiber brightener AD is relatively simple, and is generally obtained by reacting methyl phthalate with phthalic anhydride under suitable reaction conditions. During the preparation process, attention should be paid to the reaction temperature and reaction time to ensure the purity and quality of the product.
Regarding the safety information of acrylic brightener AD, it is a combustible substance and should be prohibited from contact with fire sources. During use, care should be taken to avoid direct contact with skin, eyes and respiratory tract. If inhaled or exposed by mistake, rinse immediately with clean water and seek medical attention. During storage and transportation, it should be avoided to mix with oxidants and acids. In addition, it should be kept away from children and animals.
