Abstract
The utility model relates to a novel sample ring for an asphalt softening point test with a ring and ball method. The technical scheme is that the novel sample ring comprises a sample ring and a steel ball positioning ring, wherein the lower part of the steel ball positioning ring is connected with the sample ring; the sample ring adopts a three-ring stepped structure formed by an upper ring, a middle ring and a lower ring, and the outer diameter of the middle ring is larger than the outer diameter of the upper ring and the outer diameter of the lower ring; the lower end surface of the steel ball positioning ring is attached with the upper end surface of the middle ring of the sample ring; and the inner side surface of the steel ball positioning ring is attached with the outer side surface of the upper ring of the sample ring. The novel sample ring for the asphalt softening point test with the ring and ball method has the benefits as follows: by means of the designed three-ring stepped structure, the sample ring and the steel ball positioning ring are accurately matched and positioned in the use process, and further, the hand force application position of an experimenter is provided by the upper end surface of the middle ring during the separating process, so that the sample ring and the steel ball positioning ring are easy to separate; and the accuracy and efficiency of an experiment are improved, and the experiment operation is simplified.
Description
Technical field
The utility model relates to a kind of pitch proving installation, particularly the new-type sample ring of a kind of ball and ring method asphalt softening point test.
Background technology
Asphalt softening point is one of the most basic performance index of pitch, and in pitch standard, nearly all country has all listed softening point index in both at home and abroad.Asphalt softening point is pitch isoviscous temperature under certain condition, is usually used in evaluating the high-temperature behavior of pitch, and softening point is high means that the isoviscous temperature of pitch is high, and the high-temperature stability of compound is good.
The assay method of softening point has multiple, and most representative method is ball and ring method ASTM D36.First this method injects sample ring by pitch, after cooling 30min, wipes unnecessary sample on anchor ring off with straight scraper, then puts at least 15min of Water Tank with Temp.-controlled of 5 DEG C ± 0.5 DEG C.From Water Tank with Temp.-controlled, taking out the sample ring that fills sample is placed in the circular hole of support la m, put steel ball set collar, then steel ball is placed on to the sample central authorities in the middle of locating ring, whole ring stand is put into the beaker that fills heating medium, with constant speed (5 ± 0.5) DEG C/min heating.With the rising of temperature, pitch sample is softening gradually.In the time softening to a certain degree, steel ball is because Action of Gravity Field falls from pitch sample, and now the temperature of heating medium is the softening point of pitch.
In experimentation, the pitch of melting is injected after sample ring, while wiping on anchor ring unnecessary sample off with straight scraper, pitch can adhere to outside sample ring unavoidably.Therefore when sample ring embeds when steel ball set collar, the pitch that is bonded at sample ring outside will cause the adhesion of steel ball set collar and sample ring, the accurate location between sample ring and steel ball set collar is coordinated and is impacted, thereby affect the accuracy of experimental result.And experiment finish after, sample ring is difficult to separate with steel ball set collar, usually needs to prize sample ring with screwdriver and is just separated, easily cause steel ball set collar be out of shape, bring inconvenience to experimentation.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provide a kind of ball and ring method asphalt softening point test new-type sample ring, structure is more reasonable, the embedding that facilitates sample ring and steel ball set collar with separate, to improving experiment accuracy and efficiency, simplify experimental implementation tool and be of great significance.
Its technical scheme is: comprise sample ring and steel ball set collar, the bottom of described steel ball set collar connects sample ring, and sample ring forms the staircase structure with three rings by pressed on ring, middle ring, lower ring, and the external diameter of middle ring is greater than the external diameter of upper ring and a lower ring; The middle ring upper end laminating of the lower end surface of described steel ball set collar and sample ring, the pressed on ring lateral surface laminating of the medial surface of steel ball set collar and sample ring.
The top of above-mentioned steel ball set collar is provided with hole, and lateral wall is provided with multiple side openings.
The beneficial effects of the utility model are: three ring staircase structures of the utility model design can make sample ring and steel ball set collar in use carry out accurately coordinating location, and in the process separating, the upper surface of middle ring provides experimenter's hand to put forth effort position, makes sample ring and steel ball set collar be easy to separate; Reach and improve experiment accuracy and efficiency, simplify the object of experimental implementation.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: pressed on ring 1, middle ring 2, lower ring 3, steel ball set collar 4, upper hole 5, side opening 6.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises sample ring and steel ball set collar 4, and the bottom of described steel ball set collar 4 connects sample ring, and sample ring forms the staircase structure with three rings by pressed on ring 1, middle ring 2, lower ring 3, and the external diameter of middle ring 2 is greater than the external diameter of pressed on ring 1 and lower ring 3; The lower end surface of described steel ball set collar 4 and the 2 upper end laminatings of the middle ring of sample ring, the medial surface of steel ball set collar 4 and the 1 lateral surface laminating of the pressed on ring of sample ring.
Sample ring is in order to contain pitch sample, and sample ring is placed in metal support la m circular hole.Wherein, the top of steel ball set collar 4 is provided with hole 5, and lateral wall is provided with multiple side openings 6.
In engagement process, the middle ring upper end laminating of the lower end surface of steel ball set collar and sample ring, the pressed on ring lateral surface laminating of the medial surface of steel ball set collar and sample ring, accomplishes that accurately location coordinates.
In detachment process, be difficult to separate because the adhesion effect of pitch makes sample ring and steel ball set collar, and the staircase structure of middle ring is for detachment process provides hand center of effort, makes detachment process more easy.
Claims (2)
