Description

Technical Field

[0001] The invention belongs to the technical field of glass-lined materials, and in particular relates to a high-strength, corrosion-resistant glass-lined material for chemical reactors. Background Art

[0002] Glass-lined equipment is a glassy enamel made of silicon dioxide as the main body and other elements. After multiple high-temperature sintering at 920~960℃, the enamel is firmly attached to the surface of the metal iron tire. Therefore, it has both the chemical stability similar to glass and the dual advantages of metal strength, and is an excellent corrosion-resistant equipment. It is widely used in industrial production and scientific research such as chemical industry, petroleum, metallurgy, medicine, pesticides, dyes, synthetic rubber, synthetic fibers, plastics, food and beverages, and defense industry for reactions, evaporation, concentration, synthetic polymerization, saponification, sulfonation, chlorination, nitration, heat exchange, separation, metering, storage, etc., to replace stainless steel and non-ferrous metal equipment, with excellent comprehensive performance.

[0003] Glass-lined glaze is the main raw material for manufacturing glass-lined equipment. The quality and technical level of glass-lined glaze have an important impact on the service life of glass-lined equipment. Glass-lined glaze is divided into base glaze and top glaze. The base glaze forms an interpenetration layer with the surface of the steel plate, which is the basis of the overall structure of the glass-lined glaze.

[0004] In the prior art, the performance of the base glaze still needs to be improved in the following aspects: First, the adhesion strength, especially the low-temperature adhesion strength. Poor adhesion strength will cause the base glaze to fall off and explode. Second, the tendency to scale. The more micropores in the base glaze layer, the stronger its anti-scale. Introducing oxides that can produce gas into the base glaze, refractory components such as sodium carbonate, molybdate, silicon oxide, zirconium oxide, etc., increase the micropores and air permeability of the base glaze layer. Third, the reboiling temperature. The reboiling is manifested on the porcelain surface in the form of bubbles. After firing and cooling at a certain temperature, the firing time is extended for the second time than the first time to observe the changes in the bubbles (number and size). The denser and larger the bubbles, the more serious the reboiling tendency. Fourth, the foaming temperature, which refers to the temperature at which the gas is most intensely generated when the base glaze is fired. The glaze viscosity corresponding to this temperature is 10 6 The foaming is not obvious, indicating that the exhaust performance of the base glaze is good. The fifth is the bubble structure, including porosity, distribution uniformity, and bubble size. The structure with porosity <10% and small and uniformly distributed bubbles is reasonable. The sixth is the expansion coefficient. The expansion coefficient of the steel plate is 13×10 -6 The expansion coefficient of the base glaze is controlled at 9.5×10 -6 The seventh is the firing range. The wider the firing range, the better the quality of the base glaze, which can overcome the defects such as copper head and local burning produced during enameling. The eighth is the rheological properties of the glaze slurry, that is, the suspension performance and retention. Summary of the invention

Example 10

[0030] This example is used to examine the performance of the above glass-lined materials as glass-lined base glaze.

[0031] 1. Test steps

[0032] 1.1 Pretreatment of steel plates

[0033] The same batch of steel plates were selected as the substrate and placed in a muffle furnace, and kept at 600°C for 120 minutes. Sandblasting was performed using a sandblasting machine.

[0034] 1.2 Glaze spraying

[0035] Prepare 40g of glaze according to the formula of Example 1 to Example 9, add 18ml of deionized water and mix evenly to obtain a mixed glaze; stir the mixed glaze on a magnetic stirrer for 20 minutes so that the additives are evenly dispersed in the solution. Pour the evenly dispersed glaze into the spray gun, and keep the spray gun about 30-40cm away from the steel plate during spraying. The speed of moving the spray gun needs to be kept at a constant speed during the spraying process. After spraying, place the steel plate at room temperature and let it stand for 24 hours until the glaze on the surface of the steel plate is completely dry. Dry for 24 hours after spraying the glaze.

[0036] 1.3 Enameling

[0037] Starting from 20℃, heat up to 150℃ after 45min, keep warm for 30min, then heat up to 650℃ after 45min, keep warm for 30min, then heat up to 750℃ after 40min, keep warm for 35min, then heat up to 900℃ after 35min, keep warm for 50min; starting from 900℃, cool down to 750℃ after 45min, then starting from 750℃, cool down to 600℃ after 30min, then turn off the electric furnace and cool naturally to room temperature with the furnace.

[0038] 2. Bending strength test

[0039] A three-point bending test is used, that is, a rectangular or circular specimen is placed on a bending device, an appropriate span is adjusted, and a load is added to the specimen to perform a bending test until the specified bending degree is reached or a fracture occurs.

[0040] First, pre-treat the glass-lined sample by marking it to determine its center point, then polish the center with sandpaper, and then attach the strain gauge to the determined center point.

[0041] Connect the strain gauge of the glass-lined sample to the strain meter, and place the glass-lined sample on the bending tester with the glaze surface facing down and the steel plate facing up. Use a computer to control the tester to descend at a rate of 0.5mm / min and apply a load to the glass-lined sample until the sample reaches a certain degree of bending.

[0042] The maximum bending strength calculation formula of glass-lined specimen is: P=3FL / 2bh 2 .

[0043] In this formula: P is the maximum bending strength of the specimen, in MPa; F is the maximum load value when the specimen breaks, in N; L is the span of the universal testing machine, in mm; b is the width of the glass-lined specimen, in mm; h is the thickness of the glass-lined specimen, in mm.

[0044] The experimental results are shown in Table 1 below:

[0045]

[0046] 3. Fracture toughness test

[0047] The three-point bending test is also used to test the fracture toughness. Under the applied load, due to the continuous change of displacement, a significant peak will be generated, followed by a short-term sudden change in the pressure value, called ΔF, and the corresponding displacement is called ΔX. The greater the difference between ΔF and ΔX, the greater the fracture toughness of the glass-lined sample.

[0048] The indenter of the universal testing machine moves downward at a speed of 0.5mm / min. As the displacement increases, when the indenter begins to contact the bottom of the steel plate, due to the reaction principle of force, the indenter will be supported by the steel plate. However, as the external pressure continues to increase, the compression value of the steel plate will reach its limit. If the pressure continues to increase at this time, the steel plate will resist the pressure by deforming, and the glass enamel layer on its surface will also begin to deform, causing the glass enamel to break until it breaks completely after a period of time, and the experiment ends.

[0049] The experimental results are shown in Table 2.

[0050]

[0051] 4. Hardness test

[0052] The indentation test is used for testing. The main experimental equipment is a Vickers indenter, which is a regular tetrahedron with two opposite faces with an angle of 136°. The diamond indenter is pressed into the surface of the material, and elastic and plastic deformations occur as the load increases. After unloading, the elastic deformation is restored, and indentation marks formed by plastic deformation remain on the surface of the material. The diameter of the concentric circles centered on the indentation is observed and measured using a metallographic microscope to approximately estimate the area of ​​the indentation, and the Vickers hardness (HV) is calculated using the following formula.

[0053] HV=0.102×F / S=0.102×(2Fsin(α / 2)) / d 2

[0054] Wherein, F is the applied indentation load, in N; α is the angle between the opposite faces of the diamond regular tetrahedron indenter, which is 136°; d is the diameter of the concentric circle of the indentation, in mm.

[0055] A relatively smooth area is determined on the surface of the glass-lined sample in advance, and an external force load is applied to the area through the indenter. Through multiple attempts, the indentation produced by the same sample under different external force loads is observed, and it is determined that the appropriate external load value is about 4kg, when the indentation is clearer, and it is maintained for 5s. All glass-lined samples are tested for hardness under this condition.

[0056] The experimental results are shown in Table 3 below:

[0057]

[0058] 5. Corrosion resistance test

[0059] Glass enamel is an amorphous solid with an irregular structure composed of silicon-oxygen tetrahedrons. Therefore, the corrosion process on its surface is very similar to that of glass corrosion. The main reasons are the exchange of surface ions and the erosion and dissolution of the silicon-oxygen network skeleton. When the glaze layer is corroded by acid, the hydrogen ions in the acid first replace the monovalent and divalent metal ions in the solution. As the metal ions continue to precipitate, silica gel or hydrated silicate is adsorbed on the surface of the porcelain layer to form a protective film. This protective film can effectively prevent the acid from further penetrating and corroding the inside of the porcelain layer, thereby achieving the effect of acid corrosion resistance. On the contrary, under alkaline conditions, silicon dioxide will react violently with sodium hydroxide to generate a water-soluble alkaline silicate, which completely dissolves the silicon-oxygen tetrahedral network structure, destroys the integrity of the porcelain layer, and reduces the chemical stability accordingly.

[0060] Weigh the fired samples and place them in 30vol% sulfuric acid solution. Similarly, place two groups in 1mol / L sodium hydroxide solution and seal them with plastic wrap to ensure that all variables except the mass fraction remain consistent and do not change in each beaker. In this experiment, take them out after 240h of corrosion, dry them, and calculate the remainder relative to the initial weight.

[0061] The experimental results are shown in Table 4 below:

[0062]

[0063] The above experimental results show that the present invention significantly improves the hardness, bending strength and fracture toughness of the glass-lined sample, and has excellent acid and alkali corrosion resistance. Among them, the technical effect of Example 4 is the most outstanding.
