Description

A kind of detection method of hollow glass micropearl specific gravity

Technical field:

The present invention relates to a kind of detection methods of specific gravity, are specifically exactly a kind of detection method of hollow glass micropearl specific gravity.

Background technique:

Hollow glass micropearl (hollow glass microspheres) is a kind of hollow, small, vitreous sphere, 0.2~1.2g/cm of specific gravity³, 10~250 μm of diameter, with light specific gravity, good dispersion, not soluble in water, compression strength is high, fusing point The features such as height, resistivity are high, thermal conductivity coefficient is low, Thermal Contraction Coefficient is small, is rendered as off-white powder, is widely used in artificial light material Material.

" Lee's formula specific gravity bottle " is a kind of common specific gravity detection device, is measured occupied by insoluble powder using fluid-discharge therapy Volume obtains powder specific gravity further according to powder weight, and the common liquid that detects is pure water, kerosene etc..In terms of its principle, powder It wants to submerge in liquid completely, that is, when the specific gravity of powder is greater than the specific gravity of liquid, this method is just applicable in.Due to hollow Glass microballoon specific gravity is very light, is difficult liquid needed for finding detection, therefore directly can not detect hollow glass micropearl institute using fluid-discharge therapy The volume occupied.Although also there is specific gravity detector in the prior art, it is inaccurate to the measurement result of hollow glass micropearl.

Summary of the invention:

The present invention is exactly in order to overcome the shortcomings in the prior art, to provide a kind of detection method of hollow glass micropearl specific gravity.

The application the following technical schemes are provided:

A kind of detection method of hollow glass micropearl specific gravity, it is characterised in that: it includes detecting step and calculates step, described Detecting step includes:

Step 1: weighing to hollow glass micropearl to be detected, show that the hollow glass micropearl weight weighed is W, prepare one Teat glass with volume markings line, and the interior diameter of teat glass is measured, calculating its inner section product is M；

Step 2: certain liquid being added in teat glass, records the liquid level of liquid in teat glass, both low liquid level was high Angle value S0；

Step 3: the hollow glass micropearl weighed all being slowly added into the teat glass for filling liquid, hollow glass is micro- Pearl has part and submerges in liquid, still has part to be located on liquid level；

Step 4: shaking teat glass, be uniformly distributed hollow glass micropearl along test tube dense vertical；

Step 5: recording the float position height of hollow glass micropearl, both Gao Zhuwei height value W1, record liquid level increases to New high degree, both high liquid level height value S1, record hollow glass micropearl submerged the position in water, both low pearl position height value W0；

The calculating step includes: W × (S1-W0)/(W1-W0)/(S1-S0)/M, gained be exactly submerge it is hollow in water The specific gravity of glass microballoon, the both specific gravity of hollow glass micropearl to be detected.

Based on the above technical solution, there can also be technical solution further below:

Liquid in the step 2 is water or kerosene.

Invention advantage:

The present invention has the characteristics that detection method is practical low with quick, detection range is wide, testing cost.

Detailed description of the invention:

Fig. 1 is the schematic diagram in teat glass plus after water；

Fig. 2 is that the schematic diagram after hollow glass micropearl is added in teat glass in Fig. 1.

Specific embodiment:

As illustrated in fig. 1 and 2, a kind of detection method of hollow glass micropearl specific gravity, it is characterised in that: it includes detecting step and meter Step is calculated, the detecting step includes；

Step 1: weighing to hollow glass micropearl 2 to be detected, show that 2 weight of hollow glass micropearl weighed is W, prepare one A teat glass 1 with volume markings line 1a, and the interior diameter of teat glass is measured, calculating its inner section product is M.Described Graduation mark 1a is along the axial distribution of teat glass 1, for measuring the volume for pouring into liquid in teat glass.

Step 2: certain water 3 being added in teat glass, and records the height of water level in teat glass 1, has both obtained low Height of water level value S0.

Step 3: the hollow glass micropearl 2 weighed all is slowly added into the teat glass 1 for filling water, to avoid The hollow glass micropearl 2 for unnecessarily touching water 3 touches water 3, to improve detection accuracy；Own wt, itself specific gravity and Teat glass wall constraint joint effect under, hollow glass micropearl 2 have part submerges in water, but still have part be located at the water surface it On.

Step 4: shake teat glass 1 makes hollow glass micropearl 2 along glass to reduce the gap between hollow glass micropearl 2 1 dense vertical of glass test tube is uniformly distributed.

Step 5: recording the position height of hollow glass micropearl 2 swum in teat glass 1, both Gao Zhuwei height value W1；It is submerged in water 3 since hollow glass micropearl 2 has part, the water level in teat glass 1 can also rise, and record water level The new high degree increased to, both high water level height value S1；Since 2 specific gravity of hollow glass micropearl is lighter, so submerging hollow in water 3 Glass microballoon 2 is also only suspended in the upper layer of water 3, and record hollow glass micropearl 2 submerges the position in water, both low pearl position height value W0。

Because making hollow glass micropearl along the vertical uniform distribution of teat glass by step 4, then every list on teat glass 1 Hollow glass micropearl weight in the scale section of position is W/(W1-W0) institute's value.

Proportionally share, then the hollow glass micropearl weight submerged in water is W × (S1-W0)/(W1-W0) gained Numerical value.

The increased volume of water level is then the hollow glass micropearl volume submerged in water for institute's value of (S1-S0) × M.

The calculating step is exactly to pass through above-mentioned to be derived from W × (S1-W0)/(W1-W0)/(S1-S0)/M, institute It must be exactly the specific gravity of the hollow glass micropearl submerged in water, both specific gravity of hollow glass micropearl to be detected.
