[0034] Figure 2 This is a flowchart illustrating an exemplary method for manufacturing a vinyl resin electrolytic cell according to some embodiments of this specification.
[0035] Step 210: Make a steel mold. After applying polyester surface felt to the surface of the steel mold with vinyl resin, assemble the steel mold to obtain the assembled steel mold.
[0036] The steel mold can be an electrolytic cell mold made of steel. In some embodiments, the steel mold can be used for injection molding of vinyl resin electrolytic cells. In some embodiments, the steel mold can be manufactured according to parameters such as the volume required for actual production and dimensions preset based on experience.
[0037] In some embodiments, the surface of the steel mold can be polished and waxed. In some embodiments, a layer of vinyl resin is evenly applied to the surface of the steel mold to form a gel coat, and 3-5 layers of polyester surface felt are attached. After it is fully cured, the steel mold is assembled and fastened, and then assembled on a vibrating bed in an upside-down manner to obtain the assembled steel mold.
[0038] By fabricating a steel mold and lining its surface with polyester surface felt using vinyl ester resin, an electrolytic cell mold that meets actual production needs can be obtained. This facilitates the subsequent application of polyester surface felt during electrolytic cell preparation, providing corrosion protection, leakage prevention, and liquid crystallization prevention, while simplifying the process and saving time and costs.
[0039] Step 220: Prepare the adhesive and add aggregate to the adhesive and mix to obtain the casting layer raw material.
[0040] In some embodiments, the vinyl resin can be mixed with diluent, curing agent and accelerator in the following weight percentage ratio: 90%-95% vinyl resin, 3%-10% diluent, 1%-5% curing agent and 0.1%-2% accelerator by weight, with a stirring speed of 500r / min-700r / min and a stirring time of 8min-15min.
[0041] For more information about the adhesive, please refer to the foregoing content and related descriptions in the instruction manual.
[0042] In some embodiments, aggregates may be added to the prepared binder and mixed to obtain the casting layer material. In some embodiments, the aggregates may include barium sulfate, with the amount of barium sulfate being 85%-90% of the weight of the casting layer material. In some embodiments, the aggregates may include barium sulfate of the following mesh sizes by weight percentage: 6-8 mesh 20%-40%, 10-20 mesh 20%-30%, 30-70 mesh 5%-15%, 70-140 mesh 5%-15%, and 200-300 mesh 5%-10%. The mixing speed is 60 r / min-90 r / min. The mixing time is 5 min-15 min.
[0043] For more information about aggregates, please refer to the foregoing content and related descriptions in the instruction manual.
[0044] By preparing a binder and adding aggregates to obtain the casting layer raw material, a uniformly mixed casting layer raw material can be obtained, which is convenient to add directly during the subsequent preparation of the electrolytic cell, and prevents the waste of manpower and material resources and production errors caused by repeated addition.
[0045] Step 230: Pour the casting layer material into the assembled steel mold and pre-embed the connectors. After vibration and curing treatment, a vinyl resin electrolytic cell is obtained.
[0046] In some embodiments, the casting material can be poured into the assembled steel mold, and connectors can be pre-embedded in the slag discharge hole and / or liquid discharge hole at the bottom of the electrolytic cell.
[0047] In some embodiments, the raw material of the casting layer, which is loaded into a steel mold, can be vibrated and cured, and then ejected using tools such as jacks to obtain a vinyl resin electrolytic cell.
[0048] In some embodiments, vibration treatment may involve vibrating the casting material placed in a steel mold as a whole. In some embodiments, the vibration frequency may be 40Hz to 120Hz. The vibration time may be 30min to 60min.
[0049] In some embodiments, the curing process may involve curing the vibration-treated casting material placed in a steel mold under constant temperature conditions. In some embodiments, the constant temperature may be 35-40 degrees Celsius. In some embodiments, the curing time may be 12-24 hours.
[0050] By pre-embedded connectors, pipe connections can be easily made and disassembled; after vibration and curing treatment, a vinyl resin electrolytic cell with a smooth surface, shape that fits the steel mold, and stable quality can be obtained, reducing the problem of unevenness in the vinyl resin electrolytic cell caused by insufficient vibration and curing.
[0051] In some embodiments, the method for manufacturing a vinyl resin electrolytic cell further includes processing operations such as deburring the surface after demolding, scraping the surface slurry, and spraying anti-corrosion coating.
[0052] It should be noted that the above description of process 200 is for illustrative purposes only and does not limit the scope of this specification. Those skilled in the art can make various modifications and changes to process 200 under the guidance of this specification. However, these modifications and changes are still within the scope of this specification. For example, performing step 220 before step 210, etc.
