Abstract
The utility model aims at providing a simple structure, the measuring of the rubber and plastic material density that economy is suitable for assists the utensil, the hanging has the sample mount on the ejector pin of frame, and the sample mount includes the jib, and the lower extreme of jib is fixed with the tray. The measuring principle of the scheme is that when an object is completely immersed in liquid, the volume of the object to be measured is equal to that of the replacement liquid, namely, the buoyancy measuring method comprises the steps of firstly putting a frame and a sample fixing frame on a balance weighing platform, clearing the balance reading after the weight is balanced, then putting the frame right above the electronic balance weighing platform, putting a test sample into a tray, and recording the sample mass (m) weighed by the balance S,A ) Then, the sample holder with the sample is immersed in deionized water, and this is recordedMass of sample weighed by balance (m) S,IL ) And calculating to obtain the density of the sample.
Description
Technical Field
The utility model relates to a non-metallic material performance detects technical field, concretely relates to utensil is assisted in measurement of rubber and plastic material density.
Background
At present, the density of the rubber and plastic material is mainly detected by a special rubber and plastic density instrument, and a set of complete density measuring equipment mainly comprises a balance and a density measuring instrument, so that the whole structure is complex and the price is high. For some units or departments that test less frequently or occasionally for density testing, purchasing a dedicated density measurement device can result in significant waste of assets.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, the measuring of economical and applicable rubber and plastic material density assists the utensil.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a utensil is assisted in measurement of rubber and plastic material density, includes the frame, and it has the sample mount to hang on the ejector pin of frame, and the sample mount includes the jib, and the lower extreme of jib is fixed with the tray.
The measuring principle of the scheme is that when an object is completely immersed in liquid, the volume of the object to be measured is equal to that of the replacement liquid, namely, the buoyancy measuring method comprises the steps of firstly putting a frame and a sample fixing frame on a balance weighing platform, clearing the balance reading after the weight is balanced, then putting the frame right above the electronic balance weighing platform, putting a test sample into a tray, and recording the sample mass (m) weighed by the balance S,A ) Then, the sample holder with the sample is immersed in deionized water, and the mass (m) of the sample weighed by the balance at that time is recorded S,IL ) And calculating the density of the sample, namely:
ρ IL : the impregnation solution is the density of fresh de-distilled water.

Detailed Description
The utility model provides a measurement assistive device of rubber and plastic material density, includes frame 10, has hung sample mount 20 on the ejector pin 11 of frame 10, and sample mount 20 includes jib 21, and the lower extreme of jib 21 is fixed with tray 22. The measuring principle of the above-mentioned solution is that when the object is completely immersed in the liquid, the volume of the object to be measured is equal to the volume of the displacement liquid, i.e. buoyancy measurement, first the frame is placed10 and the sample fixing frame 20 are put on a balance weighing platform together, the reading of the balance is cleared after the weight is balanced, then the frame 10 is placed right above the electronic balance weighing platform, the sample is put in a tray 22, and the mass (m) of the sample weighed by the balance is recorded S,A ) The sample 20 holder with the sample is then immersed in deionized water and the mass of the sample weighed by the balance (m) is recorded S,IL ) And calculating the density of the sample, namely:
ρ IL : the impregnation solution is the density of fresh de-distilled water.
Hanging rings 12 are arranged below the top rods 11 of the frame 10, hooks 211 are bent at the upper ends of the hanging rods 21, the hooks 211 are hung on the hanging rings 12 to form detachable connection, and the detachable structure is convenient to store.
Further, both ends downwardly extending of ejector pin 11 has two poles 13, and the lower extreme of two poles 13 is fixed through a connecting plate 14, and the face of connecting plate 14 is located the horizontal plane and arranges, and the setting of connecting plate 14 makes placing on the balance weighing platform that frame 10 can be stable.
The connecting plate 14 department is provided with base 30, and base 30's cross-section is II shape, and including the roof 31 that the face is located the horizontal plane, the both ends downwardly extending of roof 31 is provided with riser 32, and roof 31 spanes and presses on connecting plate 14, and the length of roof 31 is greater than the width of connecting plate 14 and the width of roof is less than the interval of two pole settings 13. The base 30 passes through the attachment plate 14 and is placed across and over the electronic balance weigh platform to prevent the frame 10 from tipping.
The hanging ring 12 is arranged in the middle of the top rod 11, the annular surface of the hanging ring 12 is parallel to the surface of the frame 10 and is positioned in the vertical plane, and the hook 211 and the tray 22 are respectively arranged on two sides of the hanging rod 21.
The tray 22 is in the form of a shallow barrel of circular cross-section for holding samples, typically not exceeding 10g in size.
The density of the sample is measured at least three times, and the average value is taken as the test result, and the result is retained to the third position after the decimal point.
