Description
Technical Field
The invention belongs to the field of performance detection of heavy calcium carbonate, and particularly relates to a detection method for rapidly evaluating the fineness of 700-mesh heavy calcium carbonate.
Background
Heavy calcium carbonate (triple called heavy calcium for short) is prepared by grinding natural carbonate minerals such as calcite, marble and limestone, is a common powdery inorganic filler, has the advantages of high chemical purity, good thermal stability, high whiteness, low oil absorption rate, excellent light scattering capacity, easy dispersion and the like, has good wear resistance, high chemical stability, better weather resistance, no toxicity and no odor, has no stimulation to human bodies, and is widely applied to the coating industry.
However, the premise behind whether these excellent properties of ground calcium carbonate can be exhibited in a coating is: the fineness of the heavy calcium carbonate is in a corresponding range, and particularly in an aqueous coating, the fineness of the heavy calcium carbonate directly influences the glossiness of an aqueous product, so that the fineness range of the heavy calcium carbonate is particularly concerned.
The detection method for measuring the fineness of the ground calcium carbonate is generally adopted:
1. centrifugal sedimentation type particle size analyzer: submicron particles can be measured, the application is wide, but the result is greatly influenced by environment and human, and the repeatability is poor.
2. Laser particle size analyzer: the automation degree is higher, but the equipment environment requires highly, and the step is loaded down with trivial details, and the practicality is relatively poor.
Disclosure of Invention
The invention aims to solve the problems, provides a detection method for quickly evaluating the fineness of 700-mesh heavy calcium carbonate, and is a method capable of accurately, quickly and quantitatively testing the fineness of 700-mesh heavy calcium carbonate, and the method realizes quantitative characterization of the fineness of 700-mesh heavy calcium carbonate and grade evaluation of the fineness of 700-mesh heavy calcium carbonate by preparing heavy calcium slurry with a specific ratio, standing and layering the heavy calcium slurry with the specific ratio in a measuring cylinder and recording dividing scale lines. The premise that the 700-mesh heavy calcium carbonate has excellent performance in the water-based paint product is as follows: the fineness of the 700-mesh heavy calcium carbonate is in a corresponding range, so the detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate has important research significance.
In order to solve the problems, the invention is realized by the following technical scheme:
the invention discloses a detection method for rapidly evaluating the fineness of 700-mesh heavy calcium carbonate, which comprises the following steps of:
A. preparing heavy calcium slurry with a specific ratio:
the 700-mesh heavy calcium slurry with a specific proportion is prepared from the following components in parts by weight:
20 parts of 700-mesh heavy calcium carbonate;
80 parts of water;
B. weighing 80ml of water by using a measuring cylinder, adding a sample to be tested of 20g of 700-mesh heavy calcium slurry with a specific ratio, covering a measuring cylinder cover, reversing for 10 times, and standing on a plane;
C. starting to record time, and recording the numerical value of a demarcation scale line for standing and layering 700-mesh heavy calcium slurry with a specific proportion when the time reaches 20 min;
D. and finishing the grade evaluation of the sample to be tested of the 700-mesh heavy calcium slurry with the specific proportion according to the recorded demarcation scale line numerical value.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows:
the grade evaluation standard of the sample to be tested of the 700-mesh specific proportion heavy calcium slurry in the step D is as follows:
y is more than or equal to 50ml and less than or equal to 80ml, and the fineness of the 700-mesh heavy calcium carbonate (CC700) is qualified;
y is less than 50ml or 80ml is less than y, and the fineness of the 700-mesh heavy calcium carbonate (CC700) is unqualified;
where y is the recorded demarcation scale value.
Namely:
the fineness of 700-mesh heavy calcium carbonate (CC700) with a dividing scale mark between 50ml and 80ml is qualified;
the fineness of the 700-mesh heavy calcium carbonate (CC700) with the dividing scale mark smaller than 50ml or larger than 80ml is unqualified.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: the 700-mesh heavy calcium carbonate is prepared by a wet production process.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: the water used in the detection step is deionized water.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: in the detection step, the electronic balance used in weighing is a three-digit balance.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: in the detection step, the measuring cylinder used for weighing has a capacity of 100 ml.
The grade judgment criterion in the invention is determined by combining the following two reasons:
1. after being mixed by reversing the heavy calcium carbonate (CC700) with 700 meshes back and forth for 10 times, the heavy calcium carbonate cannot be stable in water, the measuring cylinder begins to delaminate after standing, and the dividing scale mark of the liquid level is recorded in 20 minutes, so that the accuracy of the measured value can be ensured:
when y is less than 50ml, the liquid level dividing scale mark is below 50ml, or when 80ml is less than y, the liquid level dividing scale mark is above 80 ml;
when y is more than or equal to 50ml and less than or equal to 80ml, the dividing scale line of the liquid level is between 50ml and 80 ml.
2. Through the performance expression of a large amount of heavy calcium carbonate in a paint system such as whiteness, contrast ratio, achromatism, gloss, stability and the like, the obtained test result data are comprehensively analyzed, then sorted according to the performance quality sequence, and compared and analyzed with the corresponding value y of the dividing scale line of the heavy calcium carbonate in the water liquid level, the relationship between the fineness of CC700 and the gloss of a paint product is larger, the smaller the fineness of CC700 is, the higher the gloss of the paint product at 85 degrees is, and the fineness has little influence on the performance indexes such as whiteness, contrast ratio, achromatism, stability and the like.
By comprehensively considering the above two factors, corresponding grade division can be performed according to the obtained y value of the test result. The ranking determination of the present invention is divided into the above 2 ranks.
In practical application, 700-mesh heavy calcium carbonate can be graded according to the value y, which is beneficial to rapidly judging the performance of 700-mesh heavy calcium carbonate in a coating system, namely, the obtained 50ml of heavy calcium carbonate powder with y being less than or equal to 80ml can be tested in a qualified product or a first-class product coating system; for heavy calcium carbonate powders when y < 50ml, or 80ml < y, application tests of the coating system were not considered.
The premise that the excellent properties of the ground calcium carbonate can be exhibited in the coating is as follows: the fineness of the ground calcium carbonate is within the corresponding range. In particular, in water-based paint, the fineness of heavy calcium carbonate directly affects the glossiness of water-based products, which forces particular attention to the fineness range of heavy calcium carbonate.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate aims to simply, efficiently and quantitatively realize the detection and the grade evaluation of the fineness of the 700-mesh heavy calcium carbonate, and the technical scheme is not added with an additive with a special function and has the advantages that:
1. the subsequent treatment of the heavy calcium carbonate slurry is facilitated, and the obtained test result is more visual and accurate.
2. The quantitative evaluation of the fineness of the 700-mesh heavy calcium carbonate is beneficial to rapidly screening the performance of the heavy calcium carbonate powder in a coating system.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate has the following advantages:
1. in the preparation process of the ground limestone slurry, the ground limestone powder accounts for too high or too low mass percent, and the obtained experimental data has larger deviation from the actual production application.
After the heavy calcium carbonate slurry (slurry BASE) with the specific mixture ratio is prepared, the test is required to be immediately carried out, the heavy calcium carbonate slurry is placed on a table and immediately timed for 20 minutes, and the heavy calcium carbonate slurry has the advantages of simple components, convenience in addition and quickness in preparation.
2. The technical scheme of the invention provides a brand-new detection method for rapidly determining the fineness of 700-mesh heavy calcium carbonate, which is the biggest difference from the existing detection method in the detection process.
The existing test method comprises the following steps:
A. a centrifugal sedimentation type particle size analyzer;
B. laser particle size analyzer.
In the method A, in a centrifugal force field, particle sedimentation also obeys the Stokes law, and a disc centrifuge is used for rapidly settling particles and measuring the concentration change of the particles, so that the fineness and the distribution are obtained, submicron particles can be measured, the application is wide, but the result is greatly influenced by environment and human, and the repeatability is poor.
In the method B, when particles dispersed in liquid are irradiated by laser, light diffraction and scattering phenomena are generated, the smaller the particles are, the larger the scattering angle is, light rings related to the size and the quantity of the particles are formed on a focal plane after passing through a lens, and related data can be calculated by receiving the signals by a photoelectric receiver. The method has high requirement on equipment environment, complicated steps, poor practicability and poor repeatability.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate has the following characteristics:
1. in the preparation process of the heavy calcium slurry with the specific proportion, only the heavy calcium carbonate sample to be tested and the deionized water are added into the BASE, so that the interference on the test process of the fineness performance of the heavy calcium carbonate with 700 meshes is small, the accuracy of the test result is improved, and the heavy calcium slurry has the advantages of simple components, convenience in addition and quickness in preparation.
2. The preparation process of the heavy calcium slurry with the specific proportion is simple, the components except the heavy calcium carbonate powder test sample in the test are all low-price and common raw materials, the test process is quick and efficient, and the practical value of the method is improved.
3. The test result is presented by specific numerical value, and the fineness range of 700-mesh heavy calcium carbonate can be visually and quantitatively presented. The difference of the 700-mesh heavy calcium carbonate performance can be rapidly distinguished through the value y.
4. Meanwhile, the fineness performance grade of the 700-mesh heavy calcium carbonate sample can be preliminarily determined according to the y value, and a corresponding coating system is screened out for relevant application tests, so that the working efficiency is improved.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

Example 1 method for rapidly evaluating fineness of 700-mesh heavy calcium carbonate
A method for rapidly evaluating the fineness of 700-mesh heavy calcium carbonate comprises the following steps:
A. preparing heavy calcium slurry with a specific ratio:
the 700-mesh heavy calcium slurry with a specific proportion is prepared from the following components in parts by weight:
20 parts of 700-mesh heavy calcium carbonate;
80 parts of water;
in the course of experiments, the inventors found that the higher the concentration, the slower the sedimentation rate, and as a result, it appears that the inter-particle forces are not negligible, and that the higher the concentration, the higher the inter-particle forces, and the slower the sedimentation. If 30 parts of CC700 and 70 parts of water are used, the sedimentation speed is too high, and experimental detection errors can be increased. If 10 parts of CC700 and 90 parts of water are used, the sedimentation speed is slow, and the experimental detection time is also prolonged, so that the proportion of 20 parts of CC700 and 80 parts of water for final use is determined through multiple experiments, and the proportion can be used for accurately, quickly and quantitatively detecting and evaluating the fineness of 700-mesh heavy calcium carbonate.
B. Weighing 80ml of water by using a measuring cylinder, adding a sample to be tested of 20g of 700-mesh heavy calcium slurry with a specific ratio, covering a measuring cylinder cover, reversing for 10 times, and standing on a plane;
C. starting to record time, and recording the numerical value of a demarcation scale line for standing and layering 700-mesh heavy calcium slurry with a specific proportion when the time reaches 20 min;
D. finishing the grade evaluation of the sample to be tested of the 700-mesh heavy calcium slurry with the specific proportion according to the recorded demarcation scale mark numerical value;
the grade evaluation standard of a sample to be tested of the heavy calcium slurry with the specific proportion of 700 meshes is as follows:
y is more than or equal to 50ml and less than or equal to 80ml, and the fineness of the 700-mesh heavy calcium carbonate (CC700) is qualified;
y is less than 50ml or 80ml is less than y, and the fineness of the 700-mesh heavy calcium carbonate (CC700) is unqualified;
where y is the recorded demarcation scale value.
Namely:
the fineness of 700-mesh heavy calcium carbonate (CC700) with a dividing scale mark between 50ml and 80ml is qualified;
the fineness of the 700-mesh heavy calcium carbonate (CC700) with the dividing scale mark smaller than 50ml or larger than 80ml is unqualified.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: the 700-mesh heavy calcium carbonate is prepared by a wet production process.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: the water used in the detection step is deionized water.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: in the detection step, the electronic balance used in the weighing is a three-digit balance.
The detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate is further optimized as follows: in the detection step, the measuring cylinder used for weighing has a capacity of 100 ml.
The following table 1 shows the application of the detection method of the fineness of the 700-mesh coarse whiting of the invention and the comparison with the experimental results of the conventional method:
TABLE 1 comparison of the results of the test method of the present invention and two conventional methods
The fineness detection result of the 700-mesh coarse whiting obtained by the centrifugal sedimentation type particle size analyzer is as follows: the fineness of the sample of batch A was 3.5 μm, the fineness of the sample of batch B was 5.6 μm, the fineness of the sample of batch C was 7.8 μm, and the fineness of the sample of batch D was 11.6 μm.
The fineness detection result of the 700-mesh coarse whiting obtained by the laser particle size analyzer is as follows: the fineness of the A batch of samples was 3.224 μm, the fineness of the B batch of samples was 5.438 μm, the fineness of the C batch of samples was 7.869 μm, and the fineness of the D batch of samples was 11.367 μm.
The method can show the difference of the fineness performance of three batches of samples of 700-mesh coarse whiting samples for testing specifically through the obtained y value, and the fineness of the B batch of samples and the C batch of samples is within a qualified range according to the test result of the y value. The method of the invention has the same detection result with the two conventional methods.
By combining the test results obtained by the practical application, the detection method for rapidly evaluating the fineness of the 700-mesh heavy calcium carbonate can accurately and quickly determine the y value quantitatively representing the fineness of the 700-mesh heavy calcium carbonate, and can more quickly perform grade evaluation on the performance of the 700-mesh heavy calcium carbonate.
