Technical field
The utility model relates to be tested to asphalt softening point, softening point test equipment is improved, a kind of use is devised
In the tester of detection asphalt softening point.
Background technique
Pitch is a kind of noncrystalline high molecular material, and without specific solidification point or liquefaction point, it is condensed into solid by liquid
State, by solid-state melt be liquid when, generally use condition hardening point or drippage point to indicate.Pitch is in hardening point to drippage
It is a kind of viscid flow regime when temperature range between point, takes solidification point to drippage point temperature interval 87.21% as soft
Change point.Engineering asphalt softening point cannot be too low or too high, if asphalt softening point is too high, the thermal stability of pitch is too poor,
Can soften in summer, be also easy to produce the diseases such as track, if softening point is too low, equally, in winter bituminous pavement may embrittlement, and
Adverse effect is generated to construction.So softening point measurement is inevitable in engineering.
For the high-temperature stability and good cryogenic property for guaranteeing pitch, the ring and ball method in laboratory surveys the test of softening point
In, it being heated by the method for water-bath, human eye is directly observed across beaker, but since the refractive effect of beaker and water is larger,
Error in reading factor is larger, and accuracy not can guarantee yet.And single-glass beaker thermal insulation performance is poor, it may occur that the damage of heat
It loses, so that water-bath is kept constant temperature more difficult.
Summary of the invention
The purpose of this utility model is to provide a kind of for detecting the tester of asphalt softening point, solves above-mentioned technology
Problem.
In order to achieve the above object, the technical solution adopted in the utility model is:
This when, fills in a kind of for detecting the tester of asphalt softening point, including electric furnace, glass beaker, temperature of lower offer
