Abstract
The invention relates to a method for using ultrasonic wave and microwave to degelatinize apocynum, used in one additional nanometer material, wherein it is characterized in that: putting the apocynum into sealed container with diluted alkali liquid of stannic oxide nanometer powder; heating with microwave; washing with water; washing with acid, and putting it into the washing liquid whose alkali density is 1.0-2.0% with stannic oxide nanometer powder; treating with utlrasonic wave with low frequency; treating with ultrasonic wave with high frquency; washing it with acid and water, then drying. The inveniton has lower cost and high speed, without pollution.
Description
Technical field
The present invention relates to a kind of technology that makes apocynum degumming, particularly relate to a kind of nano-powder that adds and make the technology of apocynum degumming, belong to the pretreatment technology field of the raw materials for production of weaving with ultrasonic wave and microwave.
Background technology
To existing apocynum degumming technology, retrieved the research report of using chemical method and heat treated or adopting ultrasonic wave to come unstuck separately, its common drawback is a complicated operation, usually time is long and the efficient of coming unstuck is low.
Summary of the invention
The object of the present invention is to provide a kind of nano-powder that adds to make the technology of apocynum degumming with ultrasonic wave and microwave, it is economical and practical, and is with low cost, pollution-free, and speed is fast, has very high operability.
A kind ofly add nano material makes apocynum degumming with ultrasonic wave and microwave technology, it is characterized in that earlier the bluish dogbane raw ramie being put into the closed container that fills the sig water that has added stannic oxide nano powder, use microwave heating treatment, after the raw ramie washing after handling, pickling, putting into the alkali concn that has added stannic oxide nano powder is the detergent remover of 1.0-2.0%, use the lower frequency ultrasonic Treatment, and then use the upper frequency ultrasonic Treatment, afterwards bluish dogbane is carried out pickling, washing, oven dry.
Advantage of the present invention is that cost is low, comes unstuck rapidly, and is less, pollution-free to the raw ramie infringement, easily promotes.
The specific embodiment
According to the design feature of bluish dogbane raw ramie itself and the characteristics of ultrasonic cavitation effect and microwave action, at the problem that exists in the existing degumming tech, technology of the present invention is put into the bluish dogbane raw ramie closed container of the sig water that has added stannic oxide nano powder earlier, use microwave heating treatment, with the pectin in the preliminary degraded raw ramie, non-fibrous materials such as lignin and half fiber, raw ramie after will handling again is through washing, after the pickling, putting into the alkali concn that has added stannic oxide nano powder is the detergent remover of 1.0-2.0% (concentration expressed in percentage by weight), and the content of nano-powder is to contain tin dioxide powder 0.8-1.2g in every 10kg liquid in this detergent remover and the above-mentioned sig water.With handling than low-frequency ultrasonic waves, use the higher-frequency ultrasonic Treatment again, when ultrasonic wave acts on liquid solution, thereby liquid medium will be done compression and cause that with sparse periodic vibration the liquid internal each point is under pressure or the tensile force effect, and the effect of tensile force can be torn big quantity of fluid. and to form a large amount of micro-bubbles be cavitation bubble.When ultrasonic frequency hour, the cavitation bubble of formation is bigger, when frequency of ultrasonic was big, the cavitation bubble of formation was less.When these flood tide cavitation bubbles break, can discharge huge energy, can produce up to a hundreds of atmospheric local instantaneous pressure, thereby formation shock wave, the solid matter surface that is immersed in liquid internal is formed powerful impact and destruction, Here it is high-strength ultrasonic distinctive " cavitation effect ".The ultrasonic cavitation effect at first can make gelatinous layer produce a large amount of cracks, form a large amount of fragments then and enter in the liquid, big fragment continues to be ground into nano sized particles again. emulsification and dispersion rapidly under the ultrasonic wave effect. avoided being adsorbed in again the apocynum fibre surface.Hyperacoustic energy is enough to interrupt hemicellulose and the very strong chemical bond combination of lignin in the bluish dogbane colloid, and the combination of fiber and colloid is fluffed, and helps the uniformly penetrating of alkali lye in the alkali treatment process and the removal of colloid.Cavitation effect of ultrasonic waves further makes the apocynum fibre cell membrane remove. and make apocynum fibre wire-dividing broom purification occur, isolate a large amount of fiber fines, its external surface area is increased, thereby increased active area with alkali lye, make its degumming effect more obvious, when ultrasonic frequency acquires a certain degree, can also make big molecule depolymerization.Why respectively fiber crops are handled with higher and ultrasonic wave lower frequency, it mainly is scrambling at the fiber surface shape, the distribution of the microscopic dimensions in slit is at random between the fiber, when size is big, ultrasonic Treatment effect with lower frequency is more satisfactory, size hour, with the ultrasonic Treatment of lower frequency.The ultrasonic wave of height frequency acts on repeatedly, can give full play to cavitation effect of ultrasonic waves.Afterwards bluish dogbane is carried out pickling, washing, oven dry, make degummed ramie.
Nano material described in the present embodiment is the nano-stannic oxide that 725 research institutes of China Shipbuilding Industry Corporation produce.Described sig water is the aqueous solution of NaOH, sodium metasilicate or sodium phosphate trimer, and wherein concentration sodium hydroxide is 10g/L, and concentration range is 8-12g/L; The concentration of sodium metasilicate is 15g/L, and concentration range is 12-18g/L; The concentration of sodium phosphate trimer is 10g/L, and concentration range is 8-12g/L; The condition of described microwave heating treatment is: normal pressure, 100 ℃ of temperature.It is described that to carry out the pickle that pickling uses be the aqueous sulfuric acid of concentration range 0.8-1.2g/L.Described microwave heating treatment, the power of microwave are 1kW, and power bracket is 0.5-1.5KW, and the processing time is 12min, and the processing time scope is 10-15min; The weight of raw ramie is 1 with the ratio of the quality of the sig water that adds nano tin oxide powder: 15-20.Described lower frequency frequency of ultrasonic is 28KHz, the frequency range value is 25-30KHz, the lower frequency ultrasonic treatment time is 60-80 minute, described upper frequency frequency of ultrasonic is 56KHz, the frequency range value is 50-60KHz, the upper frequency ultrasonic treatment time is 10-20 minute, and the water temperature of washing usefulness is 60 ℃, and the water temperature range value is 55-65 ℃.
The present invention is not adding stannic oxide nano powder and do not using the contrast experiment of coming unstuck of ultrasonic wave and microwave treatment to show with traditional: traditional bluish dogbane raw ramie usually time is 2-3 hour, handle with ultrasonic wave and microwave through adding nano-powder, usually time is about 1.5 hours, usually time shortens nearly 1/3, and the efficient of coming unstuck can reach more than 90%, compare with traditional Degumming method, the efficient of coming unstuck can improve more than 10%.
The present invention is used to slough the non-cellulose and the hemicellulose material on bluish dogbane raw ramie surface, for spinning provides high-quality degummed ramie, and then can improve yarn quality and the retaining of being produced.
