Excuse me, how should “casting solution” be translated?

I would be very grateful if a knowledgeable friend could explain this to me. Thank you for the answer from beijingheshi; I originally thought it referred to the film-forming solution. Incidentally, here is the Baidu definition of casting solution: Casting solution refers to a polymer solution formed by dissolving membrane material – polymers – in a suitable solvent, and then adding a pore-forming agent. Different ratios of the components in the film-forming solution result in membranes with varying separation performance and geometric shapes. When spinning hollow fiber membranes, a higher concentration of membrane material is required, while for flat membranes, a lower concentration can suffice. The membrane material concentration in the casting solution is high, resulting in low water permeability and good compressive resistance of the membrane ； Conversely, it has high water permeability and poor compaction resistance. The pore-forming agent in the film-forming solution affects the molecular weight cutoff of the membrane, generally following a proportional trend. Changes in the casting solution can only alter the separation performance of the membrane within the limits permitted by the membrane material; for example, polysulfone can only be used to create ultrafiltration and microfiltration membranes, but not reverse osmosis membranes ； The significant factors affecting membrane separation performance are: membrane material > casting solution > membrane fabrication conditions > post-treatment. I am extremely grateful for 5L’s answer; it was very comprehensive and detailed.
casting solution is the film-forming solution
Reply to 2# beijingheshi: Oh, thank you. I’ll go check the Chinese explanation for that film-forming liquid again. I’m hearing about it for the first time.
=0 = Total words in the score. Please be understanding. Context is important; \"solution\" can refer to a remedy or something that acts as a solution. It seems to be the latter in this case.

Please post the link; help me check the context at http://www.ashland.com/products_services/casting_solutions.asp. Thank you. After seeing your rating, I think the issue was resolved too hastily. . . .
LZ might as well look up some Chinese information about this company; it can help with understanding. Ashland Group is a global, diversified chemical company that provides innovative products, services, and solutions to customers around the world. Its main business areas include high-quality specialty chemicals such as unsaturated polyester resins and products based on gel-coating technology, as well as fine chemical products like consumables for metal casting (such as sand-fixing resin materials and release agents), various high-grade lubricants, and water treatment solutions. Production, sales, and services are carried out in 120 countries and regions around the world. Ashland’s High Performance Materials division produces specialty chemicals and resins, as well as consumer products and adhesives for metal casting. Its products are used in the construction and building industry, packaging and labeling, transportation, maritime shipping, and the metal casting sector.

By checking out the information on adhesives, binders, etc. provided on the English website you gave, it is clear that they deal in consumables for the casting industry, rather than molding fluids. \"Solution\" refers to a particular instance or method of solving something; it is an explanation or answer. As for translating the term \"casting solution\", it might be better to render it as \"supplies for the casting industry\" rather than \"solutions for casting industry supplies\" ^^!
Reply to 6# leteblink: Thank you so much. The analysis is very accurate, and the Chinese translation is excellent as well. I’ve also saved that Chinese website address. The understanding has deepened. Thank you again! ! !
