[0002] As an inorganic chemical pigment, titanium dioxide pigment is mostly used in the fields of coatings, plastics, inks and papermaking, among which coatings account for 60%. Its main component is titanium dioxide. It is non-toxic, has the best opacity, whiteness and brightness, and is considered to be the best white pigment in terms of performance in the world at present. Titanium dioxide pigment can enhance the covering power, decorative ability and mechanical strength of the coating film, and at the same time extend the service life of the coating film. The true density of titanium dioxide pigment has varying degrees of influence on the viscosity, dispersibility, whiteness, contrast ratio, etc. of the coating during its application process, and directly affects the design of the coating formula. As an important white pigment, the accurate measurement of the true density of titanium dioxide pigment is of great significance for quality control and product application.

[0003] However, in the existing specific gravity bottle detection method, the traditional density bottle with a thermometer has a small bottle mouth, a long bottleneck, and is not easy to disperse, etc. For titanium dioxide pigment with strong adhesion and small particles, it is very easy to affect the detection accuracy due to problems such as adhesion and uneven dispersion of titanium dioxide pigment during the detection process. Summary of the Utility Model

[0023] It should be understood that the embodiments of the present utility model shown in the exemplary embodiments are merely illustrative. Although only a few embodiments of the present utility model are described in detail, those skilled in the art can easily appreciate that various modifications are feasible without substantially departing from the teachings of the subject matter of the present utility model. Accordingly, all such modifications should be included within the scope of the present utility model. Without departing from the gist of the present utility model, other substitutions, modifications, variations, and deletions can be made to the design, operating conditions, parameters, etc. of the following exemplary embodiments.

[0024] The present utility model provides a special bottle for detecting the true density of titanium dioxide. Please refer to Figure 1 , including: specific gravity bottle 1, thermometer 2, and grid-type protective cover 3;

[0025] The thermometer 2 is sleeved in the grid-type protective cover 3;

[0026] The sleeved thermometer 2 is placed in the specific gravity bottle 1 through the bottle mouth of the specific gravity bottle 1.

[0027] In some embodiments, please refer to Figure 1 , the grid-type protective cover 3 functions as a fence to protect the thermometer from being collided by the measuring substance. Before entering the specific gravity bottle 1, the sleeved thermometer 2 and the grid-type protective cover 3 are assembled. The grid-type protective cover 3 has a space for accommodating the thermometer 2 on its body. Hold the assembled thermometer 2 and enter it into the specific gravity bottle 1 through the bottle mouth. Specifically, it is suspended inside the bottle body of the specific gravity bottle 1 without touching the bottle wall. For example, the bottle mouth can be plugged with a bottle stopper, and a through hole is provided in the center of the bottle stopper. Before use, the bottle stopper is removed from the bottle mouth. The top of the thermometer 2 sleeved with the grid-type protective cover 3 can pass through the through hole of the bottle stopper and the bottle stopper is stuck on the upper part of the thermometer 2, and then the bottle stopper is plugged into the bottle mouth. In another embodiment, corresponding ground glass joints can be provided between the upper part of the thermometer and the bottle mouth to realize their connection.

[0028] Titanium dioxide is a white inorganic pigment with extremely high covering power and opacity. When measuring its density, if the thermometer is directly exposed to titanium dioxide, it may affect the measurement accuracy due to the attachment of powder and even damage the thermometer. The grid-type protective cover 3 can effectively isolate the thermometer from titanium dioxide and avoid direct contact. The grid-type protective cover 3 can also reduce the influence of dust, moisture, chemical substances, etc. in the external environment on the thermometer and ensure the accuracy of the measurement result.

[0029] The grid - frame design can increase the surface area of the protective cover, which is beneficial to the dispersion and deposition of particulate matter such as titanium dioxide. When particulate matter such as titanium dioxide contacts the protective cover, due to the blocking and dispersing effects of the grid - frame, the particles are not easily directly attached to the surface of the thermometer 2, thus reducing the measurement error caused by particle accumulation. The grid - frame design not only increases the surface area of the protective cover but also improves its overall structural strength. This design enables the protective cover to better withstand external impacts and vibrations, protecting the thermometer 2 from damage. The grid - frame design makes the surface of the protective cover easier to clean. When particulate matter such as titanium dioxide adheres to the protective cover, it can be removed by simple rinsing or wiping. The presence of the protective cover also makes the cleaning and maintenance of the thermometer easier. When it is necessary to clean or replace the thermometer, simply opening the protective cover allows for the corresponding operations. This reduces the difficulty and time of the cleaning work. The design of the grid - frame protective cover 3 makes its installation and disassembly relatively simple and convenient.

[0030] In some embodiments, the body of the specific gravity bottle 1 is frustum - shaped, the outer bottom diameter of the body is 45 mm ± 5 mm, and the height of the body is 90 mm ± 5 mm.

[0031] The frustum - shaped design is wider at the bottom and narrower at the top. This structure increases the stability of the body, especially when containing titanium dioxide or during experimental operations, and can reduce the risk of tipping or breakage caused by accidental collisions.

[0032] During the measurement process, it is possible to reduce the measurement error caused by irregular shapes. The frustum - shaped body design of the specific gravity bottle may contribute to more accurate measurement and calculation of the volume of titanium dioxide inside the bottle. Since the frustum - shape has a smooth curve, compared with other shapes such as prismatic shapes, it may be easier to accurately calculate its volume through simple mathematical formulas or instruments, thereby reducing the density measurement error caused by inaccurate volume measurement. The frustum - shaped body design may make the operations of filling, pouring out titanium dioxide, and cleaning smoother and more convenient. This helps to reduce the operation time and improve the measurement efficiency. The wider bottom of the frustum - shape helps to provide a more stable support surface, thus reducing the reading deviation caused by unstable support. The frustum - shaped design may make the inside of the bottle easier to clean and dry. Due to the wider bottom, the cleaning liquid or residues can be more easily drained, and at the same time, it is beneficial to air circulation, accelerating the drying process.

[0033] For the specific gravity bottle 1 used for density measurement, the outer bottom diameter of the body is 45 mm ± 5 mm, and the height of the body is 90 mm ± 5 mm.

[0034] The true density of powder is measured by the pycnometer method based on Archimedes' principle. The powder to be measured is immersed in an immersion liquid that wets it but does not dissolve it. After evacuating to remove air bubbles, by finding out the titanium dioxide with known density excluded from a container with known volume by the powder sample, the true density of the measured powder can be calculated.

[0035] In the present utility model, its bottleneck is shortened and the bottle mouth is enlarged. A stainless steel protective cover with a dispersion function is designed outside the thermometer 2 to achieve the purpose of reducing errors and improving the dispersion uniformity of the slurry. It is convenient for weighing and dispersing titanium dioxide when detecting the true density, reduces adhesion, and improves the detection accuracy and reproducibility.

[0036] In some embodiments, the pycnometer 1 is made of high borosilicate glass. The softening temperature of high borosilicate glass is about 821 °C, much higher than that of ordinary glass. High borosilicate glass has a low coefficient of thermal expansion. When the temperature changes, its volume changes little, which is conducive to maintaining the measurement accuracy. For the pycnometer 1 that needs to be measured at different temperatures, this characteristic helps to reduce the errors caused by temperature changes. It can also remain stable in a high-temperature environment, not easily deformed or broken. This enables the high borosilicate glass pycnometer 1 to be used in a high-temperature measurement environment without affecting the accuracy of the measurement results. High borosilicate glass shows chemical inertness when contacting most titanium dioxide products, which means it is not easy to chemically react with the measured titanium dioxide, thus ensuring the reliability of the measurement results. For the pycnometer 1 that needs to measure titanium dioxide, this characteristic is particularly important.

[0037] This enables the pycnometer 1 to be used safely and reliably in experiments such as the density measurement of molten substances. Also due to its low coefficient of thermal expansion, high borosilicate glass also performs well at low temperatures and is not easily broken due to sudden temperature changes. High borosilicate glass has high resistance to acids and alkalis, can withstand the erosion of many strong acids and strong alkalis, and is not easily corroded. High borosilicate glass has a high light transmittance, making the substances inside the pycnometer 1 clearly visible, which is convenient for observation and analysis.

[0038] In some embodiments, the reading range of the thermometer 2 is 0 - 50 °C.

[0039] The thermometer 2 within this temperature range can measure and display temperature changes more precisely, reducing the errors that may be introduced due to a wide range. The thermometer 2 designed specifically for 0 - 50 °C can focus more on this interval during the manufacturing and calibration processes, thus possibly reducing production costs. For areas where stable temperature control is required, the reading range of 0 - 50 °C is sufficient to meet the needs. This helps to ensure the stability and reliability of the thermometer 2 in these experimental environments.

[0040] In some embodiments, a sealing strip is provided inside the bottleneck of the pycnometer 1.

[0041] In the design of the pycnometer 1, also known as the density bottle, it is very important to ensure that the titanium dioxide or solid sample inside the bottle is completely isolated from the external environment. This is mainly to prevent the sample from being contaminated, evaporated, or absorbing moisture in the air, thus affecting the accuracy of the measurement results.

[0042] The sealing strip can fill the tiny gaps between the inside of the bottleneck and the stopper, effectively preventing the titanium dioxide from leaking out through the gaps. This is crucial for measuring the true density of titanium dioxide because any minor leakage may lead to deviations in the measurement results. The sealing strip is usually made of materials with strong corrosion resistance and can maintain its performance unchanged when in contact with titanium dioxide or gas for a long time. It helps to extend the service life of the pycnometer 1 and reduce measurement errors caused by corrosion. The sealing strip has a certain compressive property and can maintain its shape and sealing effect under high pressure. This is particularly important for the pycnometer 1 that needs to withstand a certain pressure, ensuring that the seal will not fail due to pressure changes during the measurement process. After setting the sealing strip, the insertion and extraction processes of the stopper may become smoother and more stable, reducing the risk of seal failure caused by improper operation.

[0043] The material of the sealing strip is usually selected from materials with good elasticity and chemical corrosion resistance, such as silicone rubber, fluororubber, butyl rubber, etc. These materials can not only effectively seal but also resist the erosion of various chemical substances, ensuring stable performance during the measurement of titanium dioxide.

[0044] Regularly check the condition of the sealing strip. If there are situations such as aging, damage, or deformation, it should be replaced in a timely manner. At the same time, when cleaning the pycnometer 1, avoid using overly strong cleaning agents or tools to prevent damage to the sealing strip.

[0045] In some embodiments, please refer to Figure 1 , the bottleneck of the pycnometer 1 is cylindrical, the height range of the bottleneck is 10 mm ± 1 mm, and the inner diameter of the bottle mouth of the bottleneck is 30 mm ± 5 mm.

[0046] Shorten the bottleneck of the pycnometer 1 for density measurement to 10 mm as much as possible, and increase the inner diameter of the bottle mouth of the pycnometer 1 for density measurement to 30 mm to facilitate the addition of the titanium dioxide sample and minimize adhesion.

[0047] When adding, removing, or measuring titanium dioxide, the cylindrical bottleneck design makes the operation more convenient and smooth. The cylindrical bottleneck design helps to reduce measurement errors caused by irregular shapes. It makes the injection and discharge of titanium dioxide more uniform and stable, thus improving the accuracy and precision of the measurement.

[0048] The cylindrical bottleneck is usually used in conjunction with a sealing cap or stopper to achieve a good sealing effect. This helps prevent changes in the titanium white powder sample due to moisture absorption, volatilization, or contact with air during the measurement process, thereby reducing measurement errors. The cylindrical bottleneck helps reduce the residue of the titanium white powder sample at the bottleneck, ensuring the accuracy of the measurement results. The design of the cylindrical bottleneck makes the specific gravity bottle 1 have better structural stability during the measurement process and is not easily deformed or broken due to external forces, thus ensuring the safety and reliability of the measurement.

[0049] In some embodiments, refer to Figure 1 , the bottom of the specific gravity bottle 1 is a flat bottom.

[0050] The flat bottom design enables the specific gravity bottle 1 to stand steadily on a horizontal plane when placed and is not easily toppled. The stable bottom reduces measurement errors caused by the shaking or tilting of the specific gravity bottle 1. The stable placement state helps reduce measurement errors caused by the shaking of the specific gravity bottle 1, which is particularly important when performing precise weighing or observing the liquid level, improving the accuracy and reliability of the experiment.

[0051] The flat bottom design makes the specific gravity bottle 1 more convenient to clean. It can more easily remove the titanium white powder residues attached to the bottom and side walls of the bottle, reducing the accumulation of residues. This is very important for titanium white powder measurement because the residues may affect the accuracy of the measurement results and avoid affecting subsequent measurements. The flat bottom design is relatively simple in the processing and manufacturing process, which can reduce production costs. At the same time, the flat bottom is also easier to match and connect with various measuring instruments and devices.

[0052] In some embodiments, the bottle body of the specific gravity bottle 1 is provided with scale lines.

[0053] By directly reading the scale on the bottle body, errors caused by transferring titanium white powder to other measuring containers, such as splashing and residue, can be reduced. The scale lines help users better control the amount of titanium white powder added to ensure that the required requirements are met. It helps ensure the standardization and comparability of the measurement results.

[0054] In some embodiments, refer to Figure 1 , the material of the grid-type protective cover 3 is stainless steel with a dispersion function.

[0055] A layer of stainless steel protective cover with a dispersion function is added to the outer layer of the thermometer 2 to disperse the titanium white powder and reduce detection errors. Titanium white powder, as a common industrial raw material, has fine particles and is easy to fly. During the temperature detection process, if the titanium white powder directly adheres to the surface of the thermometer 2, it may affect the reading accuracy of the thermometer 2. The dispersion function of the grid-type protective cover 3 can effectively disperse the titanium white powder particles, reducing the possibility of their direct adhesion to the thermometer 2, thereby reducing the interference with temperature measurement.

[0056] The columnar protective cover 3 can also prevent the thermometer 2 from being damaged by accidental impacts during measurement. The stainless steel material has excellent corrosion resistance and wear resistance, which can protect the thermometer 2 from being eroded and worn by substances such as titanium dioxide. The stainless steel surface is smooth and not easy to adhere to dirt, making it easy to clean and maintain. This helps to maintain the accuracy of the thermometer 2 and extend its service life.
