Description
Technical field
The present invention relates to a kind of bituminous treatment equipment, in particular a kind ofly carry out fused thawing furnace device at modifying asphalt.
Background technology
In the prior art asphalt applications, pitch often is used to seal, smooth-riding surface etc., and the bituminous zero pour is lower, and common asphalt stock is to be blocky, in construction process, needs to adopt thawing furnace device etc. to keep pitch to become liquid, so that smear construction.
Pitch is the complex mixture of organic compound.Divide pitch earth and tar-bitumen two big classes, pitch earth is divided into rock asphalt and petroleum pitch again.Be solid, semisolid or liquid at normal temperatures; Color is that brown is deep to black, has good cohesiveness, plasticity, watertightness and chemerosiveness resistent, is one of main body starting material of waterproof roll, coating, ointment, pitch glue and protective system.The pitch that generally is used for construction waterproofing engineering has two kinds of petroleum pitch and coal-tar pitch.
Petroleum pitch is the residue of petroleum crude oil after distillation etc. extracts gasoline, kerosene, diesel oil and lubricating oil, processes from strand again.Be divided into solid, semisolid and liquid petroleum pitch, the building petroleum asphalt in the viscous bitumen is the main raw material(s) of water-proof material.Coal-tar pitch is coking or the byproduct coal tar of producing coal gas, obtains after fractionation extracts various oil.The past coal-tar pitch is one of main raw material(s) that is used for underground outdoor water-proof and protective system, but because it has certain toxicity, environmental pollution is big, adopts recent years the water-proof material of coal-tar pitch production just being limited to use and eliminate.Modifying asphalt is meant by the oxygen blast oxidation, add catalyst oxidation, add means such as nonmetal vulcanizing agent sulfuration carries out product after the modification to pitch.
Have the small molecules hydrocarbon polymer in pitch, as paraffin etc., make the bituminous physicals big to temperature sensitivity, the low pitch of temperature becomes fragile, yielding, the trickling of the high pitch of temperature; In addition, too much active group has reduced the bituminous ageing-resistant performance.Therefore,, reduce the active group in the pitch, improved the bituminous physicals, play the effect that reduces the bituminous temperature sensitivity, improves heat-resisting and resistance to low temperature by making the polymerization of small molecules hydrocarbon polymer after the above-mentioned means modification; Simultaneously, also improve the anti-degraded of asphaltene molecule fissionability, prolonged the work-ing life of material.
High-polymer modified pitch is, and to be properties-correcting agent with the superpolymer carry out product after the modification to pitch, by modification, can improve the physics and the mechanical property of pitch class water-proof material greatly, and this is one of direction of using in construction waterproofing engineering of pitch.Using maximum is two kinds of SBS rubber and APP resins, in addition, also has chloroprene rubber, isoprene-isobutylene rubber and terpolymer EP rubber etc.These molecular weight of high polymer are big, molecular polarity group and active group are few, and be relatively stable, has that the brittle point temperature is low, melting temperature is high,, a advantage that ageing-resistant performance good strong to high low temperature adaptive faculty, therefore, can improve bituminous high and low temperature resistance and ageing-resistant performance.
What the thawing furnace of prior art adopted mostly is the enamelware pot mode, promptly adopt one pot of container, make a fire in the bottom of a pan or heat with other heating installations, but because pitch is not the good conductor of heat, conduction of velocity to heat is slow, like this, and for guaranteeing that asphalt blocks as much as possible can fusion, just need to strengthen the firepower in the bottom of a pan, so that can there be the molten asphalt of q.s and speed to be used for construction; But the way of this increasing firepower just causes the pitch in the bottom of a pan by burned, and domestic pitch fusion speed is very slow, not only expend lot of energy, and roast the asphalt tar smoke pollution working-yard of coming out, and the possibility splash is to cause the working-yard environment dirty and messy everywhere.
Therefore, there is defective in prior art, awaits improving and development.
