The role of the brightener is to convert the invisible ultraviolet radiation absorbed by the product into purple-blue fluorescent radiation, which complements the original yellow radiation to become white light, and improves the whiteness of the product under sunlight. Brighteners have been widely used in textiles, papermaking, washing powder, soap, rubber, plastics, pigments and paints.
Generally, brighteners are divided into two categories, one is water-soluble brighteners, and the other is water-insoluble brighteners. The former can be used as a brightener for paper, paint, washing powder and cotton fabrics. The latter can be used for whitening of chemical fibers and plastics.
It is often divided into:
This product is especially used for the molding and processing of various plastics and plastic products under high temperature. Because of its good heat resistance, light resistance and chlorine resistance, it is a brightener for polyester fibers. Polyester, cotton and other fiber blended fabrics The whitening effect is also particularly ideal, and can be used for the whitening of polyester stock solution.

In recent years, the competition in the offshore drilling market has become increasingly fierce. The ultra-deep wells and special process wells in the sea area of ​​the island have gradually increased, which puts higher requirements on the equipment level of the offshore drilling platform. Guided by market demand, Shengli Ocean Drilling Company aims at the advanced level of international offshore drilling equipment, and upgrades the key core equipment of the main platform. It is equipped with top drive, winch, main engine, mud pump, instrument and solid control equipment with international advanced level. The platform living area was upgraded according to the star rating, which improved the drilling construction capacity of the platform and added new chips to the market.
In view of the characteristics of different imported equipment and structural conditions, the company combines equipment management with the implementation of ISO9001 and HSE quality management system, prepares equipment maintenance accounts and operation and maintenance procedures, and establishes and maintains various equipment maintenance records. The equipment draws a maintenance lubrication chart through the database form, forming a scientific management program for system safety analysis and accident hazard investigation and processing.
In production, Shengli Ocean Drilling Company implemented advance warnings on equipment status, safety analysis and implementation of measures, and regularly checked to prevent the occurrence of major equipment liability accidents. The platform equipment reached a good state of zero defects, zero faults and zero accidents. At the end of June, the company's victory on the No. 7 platform, the Dalian Dock Repair Project, was successfully completed and will be towed to the Sun 9 well drilling construction in the Liaohe Sea.
