Abstract
The utility model relates to a rheometer adapter sample cover capable of preventing samples exposing in air and volatilization loss. When a rheometer is used for determining rheological characteristics of volatile substances, a to-be-detected sample is exposed in air, loss of volatile composites of the substance can be caused along with rotation of a rotor during determination, and then accuracy of results is affected. The cover with a covering structure can effectively shield the to-be-detected sample of the rheometer, thereby preventing mass loss of the sample due to volatilization. Besides, the cover can be fixed on the rotor of the rheometer by aids of a rotor fixing hole arranged at the top of the cover surface of the cover and a supporting leg fixing slots arranged at the bottom of the cover, thereby guaranteeing stability of the cover when in rotation of the rotor. The rheometer adapter sample cover is fast in mounting, convenient in use and fine in fixation, and can not only increase measurement accuracy of rheometers but has a certain dust-proof effect.
Description
Technical field
The utility model relates to a kind of flow graph adapter sample shade.
Background technology
When utilizing rheometer measurement to contain the rheological characteristics of volatile matter, follow the rotation of rotor will inevitably cause the loss of volatile ingredient in the mensuration process, if make testing sample not be exposed in the air as far as possible, reduce the volatilization of its volatile ingredient, the measurement result accuracy is improved relatively.Based on above idea, the utility model has designed a kind of flow graph adapter sample shade, when the rheometer measurement volatile samples, sample is hidden, and avoids the devolatilization of sample, improves the accuracy of measuring.
Summary of the invention
The purpose of this utility model provides a kind of flow graph adapter sample shade that can avoid measuring samples to be exposed to air, generation devolatilization.
The technical scheme that the utility model adopted is:
A kind of flow graph adapter sample shade includes cover and at the bottom of the extended cover of cover, it is characterized in that: the cover top of described flow graph adapter sample shade is provided with the rotor fixed orifice; Be provided with the legging fixed card slot at the bottom of the cover of described flow graph adapter sample shade.
Described a kind of flow graph adapter sample shade, it is characterized in that: the hole shape of described rotor fixed orifice and rotor cross-section shape are complementary.
Described a kind of flow graph adapter sample shade, it is characterized in that: the flute profile of described legging fixed card slot and flow graph legging shape are complementary.
Described a kind of flow graph adapter sample shade is characterized in that: the legging quantity of the quantity of described legging fixed card slot and position and flow graph and the position is set adapts.
The utlity model has following advantage:
The utility model utilizes the hood-shaped structure of self, and the testing sample of flow graph has been carried out effective covering, has avoided the loss of sample because of the volatilization generation, has not only improved the accuracy that flow graph is measured, and also has certain dustproof effect; The rotor fixed orifice that the cover top is provided with and the cover end, are provided with the legging fixed card slot, and shade effectively is fixed on the rotor portion of flow graph, the stability of shade when having guaranteed rotor rotation.
Description of drawings
Fig. 1 is the vertical view of the embodiment 1 of flow graph adapter sample shade.
Fig. 2 is the vertical view of the embodiment 2 of flow graph adapter sample shade.
Fig. 3 is the side view of flow graph adapter sample shade.
Among the figure, the 1-cover, 2-covers the end, 3-rotor fixed orifice, 4-legging fixed card slot.
Embodiment
The utility model relates to a kind of flow graph adapter sample shade.Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Described a kind of flow graph adapter sample shade includes cover 1 and at the bottom of the extended cover of cover 2, adopts transparent material, has not only reduced the own wt of shade, does not also influence in the measuring process observation to sample.The cover top of shade is provided with rotor fixed orifice 3, and the hole shape of rotor fixed orifice and rotor cross-section shape are complementary, and shade effectively are fixed on the rotor portion of flow graph.Difference according to the flow graph model, the legging quantity of flow graph rotor is different with the position is set, and the legging number of present flow graph commonly used is generally 1 to 2, when the legging number is two, the legging operated by rotary motion is distributed in the both sides of rotor being on the conplane position with rotor.Therefore, the quantity and the position of the legging fixed card slot 4 described in the utility model are with the legging quantity of flow graph with the position is set adapts.Situation when having only a legging for flow graph among the embodiment 1; Situation when for flow graph two leggings being arranged among the embodiment 2.The rotor of flow graph passes rotor fixed orifice 3, and legging embeds legging fixed card slot 4, has realized shade effectively fixing on flow graph, the stability of shade when having guaranteed the rotor running.
Following table is the accuracy of measurement contrast situation before and after the utility model uses:
(1) do contrast test with 98% ethanol:
Under room temperature condition (20 ℃), sampling 5.5ml, rotating speed is 250, minute is 5min, gets 1 data point every 1min, measures viscosity number.Measurement result is as shown in table 1 below.
Table 1 98% ethanol viscosity number measurement result
Can draw from last table, obtain first data point when beginning to be measured to, promptly during 60s, not adding the data that shade records is 1.595, is 1.941 and add the data that shade records; After measure finishing, add data that shade records and also want big when not adding shade, illustrate that adding shade has played effective function to the volatilization that prevents ethanol.
(2) do contrast test with strong aqua (content is 25.0% ~ 28.0%):
Equally under room temperature condition (20 ℃), sampling 5.5ml, rotating speed is 250, minute is 5min, gets 1 data point every 1min, measures viscosity number.Measurement result is as shown in table 2 below.
Table 2 strong aqua (content is 25.0% ~ 28.0%) viscosity number measurement result
Can draw from last table, obtain first data point when beginning to be measured to, promptly during 60s, not adding the data that shade records is 1.489, and add the data that shade records is 1.502, after measure finishing, add data that shade records and also want big when not adding shade, illustrate that adding shade has played effective function to the volatilization that prevents strong aqua.
