Example Embodiment

[0029] The present invention will be described in further detail below in conjunction with the drawings.

[0030] Such as figure 1 As shown, a production process of carbon fiber electrostatic smoke control products includes the following steps:

[0031] (1) Extract raw silk:

[0032] Extraction and selection of polyacrylonitrile precursors. Under certain polymerization conditions, the double bond of acrylonitrile (AN) is opened under the free radical action of the initiator and connected to each other into linear polyacrylonitrile (PAN) macromolecules Chain, at the same time it releases 17.5kcal / mol heat, namely:

[0033]

[0034] The resulting polyacrylonitrile (PAN) spinning solution is subjected to spinning processes such as wet spinning or dry jet wet spinning to obtain PAN precursor.

[0035] The basic characteristics of good raw yarn are: round cross section, smooth and non-destructive surface; fine crystal structure and high orientation of structural units. The fine raw silk o...

Abstract

The invention discloses a technology for producing a carbon fiber static smoking-control product. The technology comprises the following steps: 1) extracting protofilament; 2) pre-oxidizing; 3) charing at low temperature and stretching; 4) processing a die and special texture on the surface; and 5) withdrawing and packaging the product. Compared with the prior art, the carbon fiber finished product produced by a carbon fiber material has an adsorption function or a-micro magnetic field function through the special production technology, is used for placing the cigarettes, can change a nicotine molecules structure stored in cigarettes, reach a release effect, gradually reduce the nicotine and tar content in tobacco, and reduces dependency of a smoker to nicotine from a fountainhead. The carbon fiber finished product has the excellent performances of high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electric conduction, heat transfer and small thermal expansion coefficient, and can finally reach a purpose of controlling smoking and quitting smoking.

Description

technical field [0001] The invention relates, in particular, to a production process of a carbon fiber electrostatic smoke control product. Background technique [0002] Carbon fiber is a new type of carbon material that emerged in the 1960s. It refers to high strength with a carbon content of more than 90%. High modulus fiber is a fiber material with special properties, which is made from raw silk under certain pressure and temperature, pre-oxidized, carbonized and other processes. [0003] After years of development, only viscose (cellulose)-based fibers, pitch fibers and polyacrylonitrile fibers are currently used to prepare carbon fibers for industrialization. The carbonization yield of carbon-based carbon fiber is higher than that of viscose fiber, which can reach more than 45%, and because the production process, solvent recovery, and three-waste treatment are simpler than viscose fiber, its cost is low, and the source of raw materials is abundant. In addition, polyac...
