Separation cleaning fluid for processing waste hot transfer carbon belt

Abstract

The invention relates to a technology for treatment and regeneration utilization of a waste heat transfer carbon ribbon. The technology effectively separates various substances which form the waste heat transfer carbon ribbon through a novel separating cleaning liquid, and treats the substances into products with certain service value to achieve the effective recovery of the waste heat transfer carbon ribbon. The technology belongs to the environmental protection and resource regeneration utilization technical field. The technology selects four organic solvents as main compositions of the separating cleaning liquid, three of the four compositions can be selected from halogenated hydrocarbons, ketones and carboxylic ethers which have carbon chain lengths not more than 4 and aromatic hydrocarbons with substitutional groups not more than 2, wherein, the halogenated hydrocarbons comprise unsaturated halogenated hydrocarbons, the substitutional groups of the aromatic hydrocarbons can be amino groups, carboxy groups, carbonyl groups and alkyl groups and are used as a carbon powder release agent, and the other composition is low carbon alcohol and is used to effectively disperse released carbon powder in the solvents and simultaneously prevent the other three compositions from forming phosgene with light further to cause the explosion.

Description

technical field [0001] The present invention relates to a technology for the treatment and recycling of waste thermal transfer carbon ribbons. The technology uses a new type of separation cleaning solution to effectively separate various substances that make up waste thermal transfer carbon ribbons. , and processed into products with a certain use value, to effectively recycle waste thermal transfer ribbons, eliminate environmental pollution, protect the environment, and save resources. The invention belongs to the technical field of environmental protection and resource regeneration. Background technique [0002] Thermal transfer ribbon, referred to as TTR, is a consumable material in instant printing technology. It is composed of polyester film coated with toner. During instant printing, the toner is heated and transferred to the ticket paper. Ribbons are one-time consumables. [0003] In the decades since its invention in the 1970s, with the development of printing tec...
