Description
Technical field
This utility model relates to carbon fiber and manufactures equipment technology field, particularly relates to a kind of carbon fibre precursor water washing device.
Background technology
Carbon fiber (PAN) has the performance of a series of excellences such as high specific strength, high ratio modulus, high temperature resistant, resistance to chemical attack, endurance, heat shock resistance, radiation hardness, conduction, heat transfer and proportion is little, belongs to typical high-performance fiber. Thus carbon fiber is all widely applied in fields such as Aero-Space, transportation, civil construction, sports goods.
High performance precursor is the premise preparing high-performance carbon fibre, and the factor affecting precursor performance is many-sided, and the existence of defect is the basic reason affecting carbon fibre precursor quality. In polyacrylonitrile/dimethyl sulfoxide (PAN/DMSO) wet spinning process, washing is an important step, if washing process imperfection, water washing effect is bad, certainly will remaining substantial amounts of DMSO in the fibre. DMSO is as the organic impurities in fiber, in heat treatment process, can form certain fault of construction in the fibre, affects the performance of the cross sectional shape of PAN precursor, the crystalline structure of PAN fiber and final carbon fiber.
The factor affecting carbon fibre precursor water washing effect is a lot, including the hydrophilic of polymerization single polymerization monomer, Polymer Molecular Weight, the solid content of spinning liquid, the temperature and time of washing, the consumption of water, drafting process etc., wherein washing conditions is to affect the most direct factor of water washing effect. Although the method for the consumption adopt and raise washing temperature, extend the time of staying, increasing water can improve water washing effect to a certain extent, but to be subject to the restriction of the factors such as equipment, cost, technique. Ultrasonic wave water washing is widely used in precursor is washed in recent years, but the method all adopting normal pressure ultrasonic wave water washing, and in normal pressure ultrasonic wave water washing process, the bubble produced under rinsing bowl normal pressure can suppress the formation of vacuum cavities, affects ultrasonic water washing effect.
In precursor water-washing process, ultrasound wave becomes radial in the deionized water of rinsing bowl, makes deionized water flowing produce substantial amounts of bubbles of vacuum, is referred to as cavitation. The energy produced when the liquid flowing produced by this cavitation and ten hundreds of high pressure vacuum air pocket moment explosions, constantly impacts tow, makes the solvent between tow surface and tow remove rapidly, reaches the purpose of washing. But under atmospheric pressure state, the air particles dissolved in deionized water also can produce bubble when running into ultrasound wave, these bubbles are the simple gas blow-through caused by ultrasound wave, and this bubble can suppress the cavitation of even significantly ultrasonic attenuation, make ultrasonic cleaning effect be weakened.
