The invention discloses a photo-bleachable visible light initiator as well as a preparation method and application thereof, and belongs to the field of visible light photocuring. In the prior art, inthe visible light photocuring process, a curing system can absorb visible light, so that the penetrability of visible light is reduced, and the curing depth of the curing system is reduced. The photo-bleachable visible light initiator provided by the invention can successfully initiate visible light free radical photopolymerization, and a polymerized material can be changed from colored to colorless and transparent, so that the material application range is widened, and the curing depth is increased. The invention also provides a preparation method of the photo-bleachable visible light initiator. According to the preparation method, an aromatic aldehyde and a compound containing active methylene are subjected to condensation reaction to prepare the photo-bleachable visible light initiator.The synthesis method of the photo-bleachable visible light initiator is simple, the absorption wavelength of the photo-bleachable visible light initiator can be adjusted and changed through molecularstructure adjustment to adapt to light sources with different wavelengths, and the application range is wide.

The invention relates to a supply and demand data matching method and a device. Through receiving the commodity demand data sent by a seller side terminal, data processing on the commodity demand data is carried out to calculate the to-be-produced commodity quantity, when a calculation result of the to-be-produced commodity quantity is greater than zero, a to-be-produced task list is generated and is sent to a production side terminal, and the to-be-produced task list comprises the commodity information and the production quantity. According to the method, the to-be-produced commodity quantity can be automatically calculated to realize reasonable and automatic matching processing on the demand data of the seller side terminal, the supply data of a supply side and the production data of a production side, and thereby supply and demand balance is realized.
