Description
Technical field
The utility model is related to small particle rubber powder process units, belong to disintegrating apparatus technical field.
Background technology
Vulcanized rubber is a kind of not molten, infusibility high molecular material, the objects such as viscosity when elasticity, toughness and crushing and processing
Manage characteristic so that it is difficult to again its is fine crushing after the particle that room temperature is crushed to a certain size, processes 180um at normal temperatures
（80 mesh）There are suitable difficulty for following grain size rubber powder.
And rubble thermoplastics blend, Thermoplastic Elastic Material Used, sprayed on material, road surface modified asphalt modifier material, sound insulation resistance
Many products such as damping material, waterproof material, Tire production are required for using fine, micro glue powder.
The rubber powder produced with waste tire rubber may replace part raw rubber and mix in green glue stock, can not only reduce rubber
The cost of glue product not only can suitably increase the doping level of fine glue powder, can also carry if formula is suitable and uses fine glue powder
Certain performances of high rubber product, and the processing performances such as shrinking percentage and mobility that can improve sizing material.Rubber powder is alternatively arranged as building
Additive, the modifying agent of material, to improve certain performances of construction material, building element and bituminous paving.
Currently, prepare rubber, thermoplastic, thermoplastic resin fine powder method mainly have normal temperature crushing up, wet method
Comminuting method, Freezing smashing method.
Normal temperature crushing up.It generally refers in room temperature or fine powder is made by mechanism crushing at a temperature of higher than room temperature
A kind of comminuting method, pulverization principle be powder is squeezed, sheared and is milled by the effect of mechanical shear stress, sieve point
From product cut size obtained is big, and purposes is narrow, reduces the physical property of powder.
Wet pulverizing method is that the pre-treatment of powder is carried out with chemicals or water, coarse powder or coarse powder the mixture input of processing
Subtle powder smash is carried out in one or more consecutive special disk colloid mill, it is the solidifying of 10 ~ 200 micro particles that grain size, which can be obtained,
Aggressiveness.This method and process is complicated, product cost is high, Difficulty.
Freezing smashing method.Nineteen twenty-seven, a company in the U.S. propose dry ice and are refrigerant crushing rubber, paste, glue
The method of property object.Its way is will to be mixed by powder material and dry ice, puts into ball mill or grinding machine crushes.1964
Year, there is the method crushed with liquid CO 2 in Japan, using impact grinder to crush low-pressure polyethylene.
The boiling point of liquid nitrogen frozen comminuting method, liquid nitrogen is -196 DEG C, it is easy to obtain ideal cryogenic effect, liquid nitrogen is gas processed
Industry byproduct, it is colourless, tasteless, nontoxic, be not present environmental pollution, be rubber and many comparatively ideal systems of material Freezing smashing
Cryogen.Precooling treatment is also classified into liquid nitrogen using form to crush and without precooling treatment crushing.
There are precooling treatment line, all processes to carry out in a cold or frozen state, scrap rubber be sent into liquid nitrogen frozen device first,
- 40 DEG C are chilled to hereinafter, then carry out impact grinding, then screens out metal and fiber with separator, scrap rubber block is sent into powder
Crushing device crushes under freezing, enters back into fluid energy type pulverizer, fine crushing under freezing.The rubber powder grain come out from boulder crusher
By low temperature screening plant, the coarse grain return boulder crusher sifted out continues to crush.
Without precooling treatment line, a part for disintegrating process carries out at normal temperatures.Coarse crushing first removes metal through magnetic separator
Afterwards, it is sent into cooling device or is sent directly into fine crusher and carry out Freezing smashing.Using magnetic separator and screening plant, metal is isolated
And fiber, finally it is sent into cyclone separator.0.03mm (325 mesh are can get with UCC Freezing smashing methods）Rubber powder below.
The liquid nitrogen frozen pulverizing waste tire of national academy of sciences of Ukraine low-temperature physics Graduate School of Engineering exploitation prepares rubber powder
Technology, machining process route are divided into crushing and grinding two parts.Pulverizing process is to be crushed after freezing whole waste tire, and make
Rubber is separated with all-steel cord and fiber cord；Grinding process is to grind the rubber powder grain of pulverizing process, the rubber powder fineness ground
60% or more is accounted for more than 40 mesh.Rubber powder can be finely ground to 0.05mm (240 mesh by micro grinder at low temperature）Ultra-fine rubber powder.
Turbine air expansion type Freezing smashing method, turbine air swell refrigeration are an aeronautical technologies, and technical process is
The refrigerating process flow of air closed cycle.The compressed air that air compressor machine is sent out is sent into level-one after drier water removal, drying
Heat exchanger, the cold air heat exchange with coming from secondary heat exchanger adverse current, absorbs cold.Enter secondary heat exchange after so that temperature is declined
Device carries out second with the air come out from freezing chamber and exchanges heat.After so that temperature is further decreased, into turbine.Expanded refrigeration,
Temperature is set to drop to -130 DEG C.It is sent into freezing chamber and the direct heat exchange of micelle, keeps micelle quick freeze brittle, finally enters freezing powder
Broken machine crushes.Charging micelle granularity is 6 ~ 10mm, and discharging rubber powder granularity is that 60 ~ 80 purposes account for 50% or more.
Above-mentioned technology is complicated, investment is big, promotes and applies less universal.
