Description
Technical Field
The invention relates to the technical field of measurement, in particular to an oil absorption detection method and system.
Background
Oil absorption refers to the amount of oil required for a given weight of pigment to be fully wetted on the absolute surface of the particle by the oil, and is conventionally expressed in terms of several parts by weight of refined linseed oil for 100 parts by weight of pigment. Oil absorption is a physical value representing the relationship of the pigment powder to the vehicle. The oil absorption is related to the size, shape, degree of dispersion and agglomeration of the pigment particles, specific surface area and surface properties of the pigment.
In the coating industry, oil absorption is an important measure of the performance of pigments in applications. It can not only show the mixing ratio, wetting degree and dispersing performance between pigment and vehicle, but also relate to the formula of coating and various performances after film forming. It is generally desirable that the lower the oil absorption the better so that the binder of the coating can be saved.
In the prior art, the oil absorption of the pigment is usually detected by adopting an oil dropping method, i.e. oil is gradually dropped into a certain amount of pigment powder, the oil is uniformly mixed into the pigment until the dropped oil can stick all the pigments together, and then the oil absorption of the pigment is calculated based on the amount of the oil, for example, the mass of the oil is divided by the mass of the pigment powder and then multiplied by 100 to obtain the oil absorption.
However, in the above method, the oil dropping process is complicated, multiple oil drops are required, and the pigment powder and the oil are sufficiently mixed after each oil drop, resulting in a large consumption of time and labor. In addition, the method for determining the dropping liquid end point is that the end point is determined when the formed paste with uniform consistency is not cracked or broken and can be adhered to a glass plate, so that the method is very dependent on manual observation and judgment, and subjective judgment errors are caused, and the detection accuracy is poor.

fig. 2 shows a flowchart of an oil absorption detection method according to another exemplary embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
According to the above description, the existing oil absorption detection method has the problems of time and labor consumption and high labor intensity; on the other hand, the problem of insufficient reliability exists, the objective of end point judgment is strong, individual subjective differences such as personnel difference, personnel state difference, personnel responsibility difference and the like in the detection process bring large errors to detection results, the existing oil consumption detection results are integers (for example, the oil consumption/pigment powder consumption is 19g/100g), and the accuracy of oil absorption detection is low.
Based on this, the present invention proposes a new method for detecting oil absorption to avoid the above problems.
Fig. 1 shows a flow chart of an oil absorption detection method according to an exemplary embodiment of the present invention, which comprises the following steps, referring to fig. 1:
s105, mixing the powdery substance to be detected and the oil substance to obtain slurry;
s110, performing extrusion forming on the slurry under a preset extrusion condition to obtain a sheet material;
and S115, calculating the oil absorption of the powdery to-be-detected material based on the using amount of the powdery to-be-detected material and the obtaining amount of the flaky material.
In the oil absorption detection method according to the embodiment of the present invention, the oil absorption of the powdery analyte can be calculated based on the amount of the powdery analyte and the acquisition amount of the sheet-like material by mixing the powdery analyte and the oil substance into the slurry and press-molding the slurry into the sheet-like material. Therefore, the complex operation that oil is dripped and mixed for many times in the prior art is avoided, the labor and the time can be saved, and the detection efficiency is improved; meanwhile, detection errors caused by judging the oil dripping end point by manually observing the consistency, viscosity and the like of the paste are avoided, so that the accuracy of oil absorption detection can be improved.
Therefore, the oil absorption detection method is convenient to operate, can accurately represent the oil absorption index, is beneficial to stabilizing and improving the product quality, and realizes cost reduction and efficiency improvement.
In the embodiment of the invention, the powdery substance to be tested and the oil substance can be placed in a container with smooth inner surface for mixing, and the container can provide a closed environment when the powdery substance to be tested and the oil substance are mixed. Specifically, the sample may be placed in a mixer for mixing.
In embodiments of the present invention, the mixing may be performed using mechanical mixing or ultrasonic mixing. The mechanical mixing device generally includes a stirring unit and a driving unit, and the stirring unit can rotate under the driving action of the driving unit so as to mix the materials. The drive unit comprises, for example, an electric motor for providing mechanical power. Ultrasonic wave is a technology for promoting the mixing of powder in liquid, and can achieve the purpose of uniform dispersion and pulverization in a micro-area in a short time by generating strong vibration, even cavitation and diffusion effects in the liquid.
It is to be understood that any suitable mixing method can be used by those skilled in the art to mix the powdery test substance and the oil substance to obtain the slurry, and the method is not limited to the above-listed method. In addition, a suitable mixing time may be set to ensure that mixing is adequately performed.
It should be noted that, in the embodiment of the present invention, since slurry is obtained after the powdery substance to be measured and the oil substance are mixed, it indicates that the amount of the oil substance in the present invention is excessive relative to the amount of the oil substance required for wetting the powdery substance to be measured, so as to ensure that the powdery substance to be measured is sufficiently wetted and the mixed slurry has a certain fluidity.
The preset pressing conditions may include preset pressing apparatuses, parameter settings of the pressing apparatuses, and the like. In an embodiment of the invention, the slurry is extruded using an extrusion apparatus. The extrusion process is to apply an external force to the material to obtain a finished product of a specific shape and/or size. In one embodiment of the invention, the slurry may be extruded using a twin roll mill. The roll-to-roll machine generally comprises a plurality of rollers and corresponding driving devices, two adjacent rollers rotate oppositely through the driving devices, and acting force is applied to materials between the two adjacent rollers.
Further, the oil absorption detection method according to the embodiment of the invention further includes adjusting the roller spacing of the twin-roller machine to a predetermined roller spacing, and/or adjusting the extrusion pressure of the twin-roller machine to a predetermined extrusion pressure, so as to improve the extrusion forming effect of the twin-roller machine on the slurry, and obtain the sheet material with a proper shape. The roller spacing and/or the pressing pressure of the twin-roller machine can be set according to the dosage of the powdery substance to be measured. In the embodiment of the invention, the preset roller spacing of the double-roller machine can be 0.1-2 mm, the preset extrusion pressure of the double-roller machine can be 0.5-5 MPa, and the dosage of the powdery substance to be measured can be 5-100 g. The setting of the parameter ranges can ensure that the slurry can smoothly pass through the double-roller machine, and can also ensure that the slurry is extruded and formed and redundant oil substances are removed.
Fig. 2 shows a flowchart of an oil absorption detection method according to another exemplary embodiment of the present invention, and the steps other than step S207 and step S209 are similar to those in fig. 1 and are not repeated.
Referring to fig. 2, the oil absorption detection method according to the embodiment of the present invention further includes: and removing redundant oil substances in the slurry based on the fact that the ratio of the using amount of the oil substances to the using amount of the powdery to-be-detected substances exceeds a preset value. Specifically, in step S207, it is determined whether a ratio of the usage amount of the oil substance divided by the usage amount of the powdery substance to be measured exceeds a preset value; if yes, in step S209, removing redundant oil substances in the slurry, and then performing step S210 and step S215; if the judgment is no, the steps S210 and S215 are directly performed. In the method for detecting oil absorption of the present invention, if the ratio of the amount of the oil substance to the amount of the powdery material to be detected is too high, the slurry is difficult to be extruded, and therefore, the amount of the oil substance in the slurry needs to be controlled. Further, the removed oil substances can be recycled, so that unnecessary waste is avoided.
In the embodiment of the invention, the redundant oil substances can be removed by centrifugal separation or screening. Centrifugal separation methods utilize centrifugal force of rotational motion and separate materials based on differences in sedimentation coefficients or buoyancy densities of the materials. The sieving method separates substances having different particle size grades by using a sieve, and for example, the separation can be performed by using a sieve having a specific sieve size.
Further, the step S115 and the step S215 of calculating the oil absorption of the powdery analyte based on the usage amount of the powdery analyte and the obtained amount of the flaky material may include: and calculating the difference between the using amount of the powdery to-be-detected material and the obtained amount of the flaky material, and dividing the difference by the using amount of the powdery to-be-detected material to obtain the oil absorption. Oil absorption can be expressed as a percentage. Specifically, after extrusion molding, the entire sheet material is collected and the amount obtained is measured to prevent the sheet material from being collected insufficiently to cause final detection errors. In the embodiment of the present invention, the amount of the powdery analyte, the amount of the oil substance, and the amount of the flake-like material obtained are all expressed in the same measurement manner, for example, all expressed by weight.
Further, the amount of the powdery analyte may be set according to the capacity of the mixing container and the throughput of the extrusion apparatus. In order to reduce system errors and avoid material waste, the amount of the powdery substance to be measured can be preferably 5-100 g.
According to the above description, the amount of oil used in the present invention is in excess of the amount of oil required for just wetting the powdery test substance. Further, in order to ensure that the powdery substance to be detected is fully soaked and the mixed slurry has good fluidity, the ratio of the amount of the oil substance to the amount of the powdery substance to be detected can be preferably 0.5-3. In the embodiment of the invention, the fluidity of the slurry can be set to be 0.5-10Pa.sThe slurry is prevented from flowing too viscous to be difficult to pass through the roll pair machine, and meanwhile, the phenomenon that the slurry flows too thin directly through the gap of the roller of the roll pair machine to enable the roll pair machine not to extrude is avoided.
In the embodiment of the invention, the ratio of the using amount of the powdery to-be-detected material, the roller spacing and the extrusion pressure of the double-roller machine and the using amount of the oil substance to the using amount of the powdery to-be-detected material can be optimized and fixed, so that the application and popularization are facilitated.
Therefore, the invention can eliminate the subjective judgment error of 'forming paste with uniform consistency just not to crack and break and being the end point when the paste is adhered on a glass plate' in the existing detection method by quantifying the parameters of the dosage of the powdery substance to be detected, the dosage of oil substances, the pressure of a double-roller machine, the distance between rollers and the like, and can eliminate the detection difference caused by different manpower and responsibility center differences.
In an embodiment of the present invention, the powdery test object may include a pigment. The pigment is a powdery substance for coloring, and can be uniformly dispersed in a medium such as oil or fat to color the medium. The pigment is mainly applied to the industries of paint, printing ink, printing and dyeing, papermaking, plastic products, rubber products and the like. Specifically, the powdery substance to be tested of the invention can comprise titanium dioxide, which is a white pigment with optimal performance and most extensive use. The oil absorption detection method can provide detection of the key quality index of oil absorption for titanium dioxide production.
In embodiments of the present invention, the oil material may comprise any suitable flowable oil, such as various vegetable oils, synthetic oils, and the like. In one embodiment, the oil material may include linseed oil.
According to the description above, the oil absorption detection method provided by the invention can well eliminate the influence of individual subjective difference on the detection result, improve the accuracy and precision, liberate manpower, save time and have strong popularization and application performance, and can be popularized and applied in a titanium dioxide production line and further in the titanium dioxide industry.
According to another aspect of the present invention, there is also provided an oil absorption amount detection system including: mixing device, pressing device and measuring device for carrying out said oil absorption detection method. The mixing device is used for mixing the powdery substance to be tested and the oil substance to obtain slurry, and can be a mechanical mixing device or an ultrasonic mixing device. The extrusion equipment is used for extruding and forming the slurry to obtain the flaky material, and the extrusion equipment can be a double-roller machine. The measuring equipment is used for measuring the using amount of the powdery substance to be measured, the using amount of the oil substance and the obtaining amount of the flaky material, and the measuring equipment can be used for measuring the weight of the substance. Further, the system may further comprise a separation device for separating excess oil substances from the slurry. The separation device may for example be a centrifugal separation device or a sieving device.
