Description
Technical field
The utility model belongs to the technical field of emulsified olefin preparation, is specifically related to a kind of device of continuous preparation emulsified olefin.
Background technology
The full name of paraffin is a petroleum wax, be lubricating oil distillate from the crude distillation gained through solvent treatment, solvent dewaxing, again through solvent deoiling, refining and sheet or needle crystal.Paraffin is of many uses, and has biological degradability, possesses more superior environmental-protecting performance than other substitute (plastics such as Vilaterm).But owing to be solid under the paraffin normal temperature, can not satisfy the purposes variety and maybe should use inconvenience, remedy its deficiency so people study emulsified olefin.Emulsified olefin is the aqueous uniform fluid of a kind of content of wax that paraffin forms under the stirring action of emulsifying agent and machinery; Owing to produce that emulsifying wax technology is simple relatively, facility investment is fewer and can use at normal temperatures; Need not with dissolution with solvents in use, film forming is even, spreadability good, concentration can obtain dilution than other wax, have safety, plurality of advantages such as economic, convenient in board materials production, printing-ink, rubber industry, agricultural is fresh-keeping and field such as daily chemical products is widely used.For example in the artificial board shaping process; Add a certain amount of wax, can improve waterproof, the humidity resistance of sheet material, make the surface brighter and cleaner; Use emulsifying wax and directly compare, have the paraffin of reduction consumption, reduce production costs and improve advantages such as board quality adding material after paraffin or the fusion.
The performance index that qualified emulsified olefin has leave standstill stability, pH value of solution value, disperse phase particle diameter and outward appearance.The principal element that influences the emulsified olefin performance index has emulsifiers formula and emulsifier unit.Emulsified olefin device commonly used at present mainly contains following several kinds:
1. mechanical stirrer is the simplest a kind of emulsified olefin device, specifically is that the high-speed stirring blade is housed in a container, thereby accomplishes emulsification through the high speed rotating of blade.Its key distinction of mechanical stirrer miscellaneous in the market changes emulsifying effectiveness through high-speed stirring blade form difference.The advantage of this method is that facility investment is little, in industry, uses wider; Shortcoming is that the emulsified olefin particle processed of this device is big and inhomogeneous, less stable, and different along with system, proportioning and container size and shape, and its effect differs.
2. static mixer; This device mainly is through letting the various types of panel elements of high-speed liquid impact flow in pipeline, and swiftly flowing liquid forms violent turbulent flow when the collision element; Form violent eddy current with the vertical section of liquid; The shearing force that produces acts on fluid again, makes it further to cut apart mixing, finally forms milk sap.The major advantage of this device is simple in structure, easily manufactured, processing ease; Shortcoming is that emulsifying effectiveness is not obvious.
3. colloidal mill, its principle of work be liquid when receiving centrifugal action, force through between the stator of high speed relative movement and rotor, rubbing, shear, effectively pulverized, emulsification, homogeneous, dispersion, mixing, thereby obtained emulsified olefin.Its major parts is rotor and stator, comes the emulsified olefin of production demands of different through the distance between adjustment rotor speed, stator and the rotor; Shortcoming is that the surface is easy to wear, influences thinning effect.
4. high pressure homogenizer, this device with high pressure reciprocating pump as transmitting and mass transport power, with mass transport to one-level homogenizing valve and secondary Emulsified valve.Material is not when passing through, and one-level homogenizing valve and secondary Emulsified valve all fit together closely, when material passes through; Under the liquid high pressure effect, spool and valve seat are squeezed by the strong hand by material and open a slit, and material is through the one-level homogenizing valve time; Pressure drop; Make it to form cavitation, material forms shearing action in slit, makes the material micronize; Thereby micronized material forms required emulsified olefin after the secondary Emulsified valve carries out emulsification.The advantage of high pressure homogenizer is that the material thermal value is little, and refining effect is good, can form uniform emulsified olefin; Shortcoming is that power consumption is big, and maintenance workload is big, for the big material poor effect of viscosity.
5. high-shear emulsion machine, this device at first make through fluid power shearing action and pressure wave effect and the material micronize through under the high shear of rotor, form great pressure gradient field again, under three's effect, carry out emulsification.The main working parts of this equipment configuration is one or more levels rotor-stator.Its main difference is the difference of the stator structure of rotor.Its major advantage is to handle different materials through changing different rotor-stators; Shortcoming is that treatment capacity is little.
In sum; All there is the shortcoming of batch production in these emulsified olefin devices; And the emulsifying agent consumption is generally bigger than normal, it is high that emulsifiers formula is required, and this is because paraffin is solid at normal temperatures, must be through heating before the emulsification; When emulsification, be prone to stressed inhomogeneous, emulsified olefin that therefore can not the production size distribution is even, the shelf time is long.In order to improve emulsifying effectiveness, thereby need the emulsifiers formula of high request or strengthen the cost that the emulsifying agent consumption increases emulsified olefin, infeasible economically.In addition, these devices are high to the emulsifying process conditional request, therefore inhomogeneous, the poor stability of emulsified olefin size distribution of preparation.
