In the chemical fiber production industry, the raw materials are cotton pulp and wood pulp, which are sulfonated to form sulfonate cellulose, which is then broken, ground, and filtered to form a gelatinous fluid (commonly known as viscose). The viscose passes through the spinneret The chemical fiber is formed in the acid bath, and the spinneret is assembled on the combined flower board. The chemical composition of dilute sulfuric acid, phosphoric acid, acid solubility of 125 g / L, so the combination of flower board material required sufficient strength, with high corrosion resistance, most parts and the corrosive medium in contact with plastic and lead-lined Lined with epoxy glass, but due to strength and temperature, limiting its application, it must be made of corrosion resistant alloy materials. The combination of stainless steel spinneret spinneret board has poor corrosion resistance, and it is difficult to meet the needs of the use. Ni-base alloys and Hastelloys have poor processing performance and high production costs, making it difficult to meet the dimensional accuracy requirements of parts. There are dozens of large-scale chemical fiber manufacturers in China, and the consumption of the combo plate of the spinneret is very large. Almost all of them depended on imports before, the import price was expensive, and the supply was not timely, causing many problems for the production of the company. Chemical fiber manufacturers commissioned us to develop an alternative product to meet production needs. After analyzing and studying the operating conditions of this part, it was decided to choose ultra-low carbon and high molybdenum austenitic stainless steel materials, which have good corrosion resistance in both oxidizing and reducing media, and even approach or exceed the resistance of titanium or nickel-based alloys. Corrosion performance. A series of blanks were produced by intermediate frequency furnace smelting and investment casting methods and then machined. In the processing process, the material processing performance is good, the accuracy of the parts is easy to ensure, and the assembly is used on the production line. There is no glue leakage phenomenon and it feels good. However, the phenomenon of intergranular corrosion occurs in less than half a year, and the service life does not exceed 8 months. The Hastelloy alloys were used to manufacture the parts. Due to the high requirements for machining accuracy of the parts, the Hastelloy has strong corrosion resistance but poor processing performance and it is difficult to achieve the accuracy of the parts. And the material prices are very high and it is difficult to meet the market needs.
Floor compound glue: It is a kind of glue mainly used in solid wood floor, ordinary wood floor and high-grade wood floor manufacturers. It meets the requirements of process production parameters and meets the requirements of environmental protection and bonding strength. Yongte-resistant floor composite adhesive is an advantageous product in the woodworking adhesive series, which can be customized according to customer needs to meet the needs of customers' specific application process.
