The export products are basically low-end titanium dioxide, and high-end products still need to be imported. From the perspective of the overall export volume of titanium dioxide in the foreign market is indeed good, but throughout the domestic market, the price of titanium dioxide has been rising from last year to now, many domestic titanium dioxide companies prefer to export low inventory processing inventory, are not willing to cut prices. At present, titanium dioxide is mainly exported to India and other Southeast Asian countries. The export products belong to low-end products. However, domestic high-end titanium dioxide products, such as high-end titanium dioxide for lithium titanate batteries, still need to be imported.
The limitations of the domestic titanium dioxide industry are increasingly evident. The gap between China and international giants in terms of technology, product quality, etc. is very large. Although China is a major producer and exporter, the manufacture of high-end downstream products still requires the import of a large amount of titanium dioxide every year. In the international market, we are often at a low price. The embarrassing situation.
Product upgrading is the key to improving quality. In the current environment of supply-side reform and environmental supervision, titanium dioxide enterprises should seize the opportunity to seek technology that is suitable for the industry's energy-saving, emission-reducing, circular economy and environmentally friendly cleaner production. With the help of environmental protection, enterprises should be forced to promote product upgrades and upgrades. product quality. However, the disposal of the three wastes requires huge investments. Enterprises must pay close attention to product quality and one-handed environmental protection. If there is no strong economic strength, this road will become increasingly difficult.
Sodium hydrosulfite is widely used in the textile industry for reducing dyeing, reducing cleaning, printing and decoloring, and for bleaching silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the bleached fabric has bright color and is not easy to fade. In terms of various substances, sodium silicate can also be used for food bleaching, such as gelatin, sucrose, honey, etc., soap, animal (vegetable) oil, bamboo, porcelain clay, etc. Sodium hydroxide can also be used in organic synthesis, such as reducing agent or bleaching agent in the production of dyes and medicines. It is the most suitable bleaching agent for wood pulp and papermaking. Moreover, many heavy metal ions such as Pb2+ and Bi3+ can be reduced to metals in water treatment and pollution control, and it can also be used to preserve food and fruits. However, due to the many dangers of sosso, many of its uses tend to be replaced by thiourea dioxide, which is safer and easier to store and transport.
