Water-bitumen emulsion is highly appreciated by building and road construction companies. \u00a0This is due to \u00a0its ease and safety of use \u00a0in comparison with the mixtures based on solvents of and from petroleum products such as kerosene. \u00a0As a rule, water-bitumen emulsion is obtained by blending liquid bitumen with water \u00a0and special emulsifiers and acids.<\/p>\n
Having years of experience in designing and building blending machines and bitumen emulsion units, Gl\u043ebeC\u043ere<\/i><\/b> is one of the most reliable manufacturers of modern equipment for production of water-bitumen emulsions anywhere in the wolrd today.<\/p>\n
A colloid mill is considered to be the heart of any bitumen emulsion production equipment where bitumen is grinded into \u00a0small droplets and is then evenly distributed in water. \u00a0In the past, manufacturers of equipment used blending equipment such as dispergators and ultrasonic homogenise that perform the wet grinding of the dispersed \u00a0phase of bitumen production.<\/p>\n
Gl\u043ebeC\u043ere <\/i><\/b>Colloid mills for wet grinding can produce highly-stable dispersed systems from two or more \u00a0mutually insoluble \u00a0substances. \u00a0Bitumen emulsion units (depending on the desired size of bitumen droplets) use three groups of colloid mills.<\/p>\n
The first group of colloid mills provides 90% of droplets with a size of less than 5 microns (a minimum size of a droplet of 1-2 micron). \u00a0They are used \u00a0to manufacture polymer-modified emulsions, bitumen emulsions for surface treatment ( “chip seal”), recycling, soil stabilization, grouting, tack coating and similar technological processes.<\/p>\n
The second group of colloid mills provides 90% of droplets at the outlet with the size of less than 10 microns (a minimum size of a droplet of 4-5 micron). \u00a0The areas of its application include: simple slurry mixtures, surface treatment, tack coting, recycling, and grouting.<\/p>\n
The third group of colloid mills produces bitumen emulsions with a minimal size of a droplet of more than 5 microns (no more than 10% of droplets are larger than 10 microns). \u00a0Such bitumen emulsions are used \u00a0for surface treatment, tack coating and grouting.<\/p>\n
Since colloid mills are mostly mounted in line with continuous blending units, components are supplied directly to the unit. \u00a0As a rule, the water phase is prepared in advance to withstand the required temperature, PH level and emulsifier metering. \u00a0Then the water phase and warmed-up bitumen are supplied to the input of the colloid mill to be \u00a0dispersed. \u00a0If necessary, the viscosity of bitumen is reduced by injecting \u00a0flux \u00a0to the feed line.<\/p>\n
The ratio of components is maintained automatically by metering pumps in accordance with the program or by temperature control of the source components, by measuring the temperature of bitumen emulsion at the outlet (as a rule it is 85-94\u00b0\u0421) \u00a0and \u00a0the subsequent flow adjustment.<\/p>\n
If required (depending on the formula), the colloid mill may be supplied with latex that allows for modified bitumen emulsion production. \u00a0At the outlet of a colloid mill, there is a three-way valve that provides recycling of water solution of emulsifier, mill flushing or discharge of the finished bitumen emulsion product.<\/p>\n
GlobeCore<\/i><\/b>‘<\/b>s<\/i><\/b> continuous bitumen emulsion equipment has a wide range of benefits that include; (1) a rapid change of the type of emulsion produced; (2) no impact of reagents on the staff; and (3) low operating costs.<\/p>\n","protected":false},"excerpt":{"rendered":"
