Organotin catalyst T12 is widely used in furniture manufacturing, covering multiple links from raw material processing to finished product processing. The following are the specific application of T12 in different furniture manufacturing processes and its impact on product quality:<\/p>\n
Polyurethane foam is a commonly used filling material in furniture manufacturing and is widely used in sofas, mattresses, seats and other products. As an efficient catalyst, T12 plays an important role in the preparation of polyurethane foam. Its main functions include:<\/p>\n
Accelerating foaming reaction<\/strong>: T12 can significantly increase the reaction rate between isocyanate and polyol, shorten the foaming time, and make the foam structure more uniform and dense. Studies have shown that polyurethane foam catalyzed with T12 foaming speed is 20%-30% faster than products without catalysts, and the foam pore size distribution is more uniform, improving product comfort and support. <\/p>\n<\/li>\n Improving foam performance<\/strong>: T12 can not only accelerate the reaction, but also effectively inhibit the occurrence of side reactions, reduce bubbles and holes in the foam, and improve the mechanical strength and durability of the foam. According to a study by Polymer Engineering and Science (2018), polyurethane foam catalyzed with T12 showed significant advantages in compression strength, resilience and tear resistance, with the product service life increased by about 15%. <\/p>\n<\/li>\n Reduce energy consumption<\/strong>: Since T12 can play a catalytic role at lower temperatures, it can reduce the use time and energy consumption of heating equipment and reduce production costs. At the same time, low-temperature foaming can also help reduce the volatile loss of raw materials and improve the utilization rate of raw materials. <\/p>\n<\/li>\n<\/ul>\n PVC (polyvinyl chloride) is a commonly used plastic material in furniture manufacturing and is widely used in the surface decoration of desktops, cabinets, door panels and other components. T12 is mainly used to promote the migration and cross-linking reaction of plasticizers during the processing of PVC plastics, which are specifically manifested as:<\/p>\n Improving flexibility<\/strong>: T12 can promote the uniform distribution of plasticizers in PVC resin and enhance the flexibility and ductility of the material. This is especially important for the production of complex furniture parts, which can reduce cracking and deformation caused by bending or stretching. According to the Journal of Vinyl and Additive Technology (2019), the flexibility of PVC materials catalyzed using T12 has been improved by about 20% at low temperatures, and the impact resistance has also been significantly improved. <\/p>\n<\/li>\n Improving anti-aging performance<\/strong>: T12 can effectively inhibit the aging of PVC materials during long-term use and extend the service life of the product. Research shows that T12 forms a more stable molecular structure by promoting crosslinking reactions, reducing the erosion of PVC materials by ultraviolet rays, oxygen and moisture. Experimental data show that after one year of exposure to PVC material catalyzed in outdoor environments, the yellowing rate was only 5%, which was far lower than that of products without catalysts (15%). <\/p>\n<\/li>\n Reduce VOC emissions<\/strong>: T12 can promote the rapid migration of plasticizers, reduce its volatility during processing, and thus reduce VOC (volatile organic compounds) emissions. This not only helps improve workshop air quality, but also meets increasingly stringent environmental standards. According to research by Environmental Science & Technology (2020), PVC materials catalyzed using T12 are inVOC emissions during the construction process have been reduced by about 30%, meeting the requirements of the EU REACH regulations. <\/p>\n<\/li>\n<\/ul>\n Coatings and coatings are important links in furniture surface treatment, which directly affect the appearance quality and durability of the product. T12 is mainly used to promote cross-linking reactions during the construction of coatings and coatings to form a strong protective layer. Its specific applications include:<\/p>\n Accelerate the curing speed<\/strong>: T12 can significantly increase the cross-linking reaction rate of resin in the coating, shorten the curing time, and enable the coating to achieve ideal hardness and gloss faster. This is particularly important for furniture companies that produce large-scale products, which can improve production efficiency and reduce inventory pressure. According to the study of Progress in Organic Coatings (2017), the curing time of coatings catalyzed using T12 was reduced by about 50% at room temperature, and the adhesion and wear resistance of the coating were significantly improved. <\/p>\n<\/li>\n Enhanced Weather Resistance<\/strong>: T12 can promote the cross-linking reaction of resins in the coating, form a denser molecular structure, and enhance the coating’s weather resistance and UV resistance. This allows furniture to remain beautiful and durable for longer periods of time outdoors or humid environments. Experimental data show that the coating using T12-catalyzed still maintains good gloss and color stability after two years of outdoor exposure, while products without catalysts showed obvious fading and peeling. <\/p>\n<\/li>\n Improving anti-corrosion performance<\/strong>: T12 can promote the even distribution of anti-rust agents in the coating, enhance the anti-corrosion performance of the coating, and extend the service life of furniture. This is particularly important for metal frame furniture, which can effectively prevent oxidation and corrosion of metal parts. According to the study of Corrosion Science (2018), the coating using T12 catalyzed showed excellent corrosion resistance in the salt spray test. After 1000 hours of testing, the coating was still intact without catalyst added. There was obvious rust. <\/p>\n<\/li>\n<\/ul>\n Wood adhesive is an indispensable material in furniture manufacturing, used to connect and fix various wood parts. T12 is mainly used to promote cross-linking reactions in the optimization of wood adhesive formulations and enhance the bonding strength and durability of adhesives. Its specific applications include:<\/p>\n Improving bond strength<\/strong>: T12 can promote the cross-linking reaction of resin in adhesives, form a stronger molecular structure, and significantly improve bond strength. This is especially important for furniture with complex structures, ensuring tight connections between the components and avoiding loosening and falling off. According to the Journal of Adhesion Science and Technology (2019), wood adhesives catalyzed with T12 show significant advantages in both shear strength and peel strength, with product bonding strength increased by about 25%. <\/p>\n<\/li>\n Improving water resistance<\/strong>: T12 can promote the uniform distribution of waterproofing agents in adhesives, enhance the water resistance of adhesives, and prevent degumming caused by moisture penetration. This is particularly important for the production of outdoor furniture or furniture in humid environments, and can extend the service life of the product. Experimental data show that after soaking wood adhesive with T12 catalyzed for 24 hours in water, the bonding strength remains above 90%, while products without catalysts have obvious degumming. <\/p>\n<\/li>\n Shorten curing time<\/strong>: T12 can significantly increase the curing speed of the adhesive, shorten assembly time, and improve production efficiency. This is particularly important for furniture companies that produce large-scale products, which can reduce waiting time and reduce production costs. According to the Industrial Crops and Products (2020), the curing time of wood adhesives catalyzed using T12 is reduced by about 30% at room temperature, and the bonding strength can reach an ideal level in a short period of time. <\/p>\n<\/li>\n<\/ul>\n The application of organotin catalyst T12 in furniture manufacturing can not only improve production efficiency, but also significantly improve product quality. The following are several specific improvement strategies, coveringFrom raw material selection to production process optimization:<\/p>\n By reasonably selecting and proportioning raw materials, combined with the catalytic action of T12, the overall performance of furniture products can be effectively improved. For example, in the preparation of polyurethane foam, a more uniform and dense foam structure can be obtained by adjusting the ratio of isocyanate to polyol and combining with the efficient catalysis of T12. Studies have shown that when the ratio of isocyanate to polyol is 1:1.2, the foam catalyzed with T12 shows excellent performance in terms of compression strength, resilience and tear resistance. In addition, suitable plasticizers, fillers and other additives can be selected according to different application scenarios to further optimize the formula and improve the comprehensive performance of the product. <\/p>\n Improving production processes is a key link in improving product quality. By introducing T12, existing production processes can be optimized to improve production efficiency and product quality. For example, during the processing of PVC plastics, low-temperature extrusion technology can be used, combined with the efficient catalysis of T12, to reduce the use time and energy consumption of heating equipment and reduce production costs. At the same time, low-temperature processing will also help reduce the volatile loss of raw materials and improve the utilization rate of raw materials. In addition, it can also achieve accurate control of the production process through automated production lines and intelligent control systems to ensure stable and consistent product quality in each batch. <\/p>\n With the continuous increase in environmental awareness, furniture manufacturing companies pay more and more attention to the environmental performance of their products. As a low-toxic and environmentally friendly catalyst, T12 can meet increasingly stringent environmental standards without sacrificing product quality. For example, during the construction of coatings and coatings, T12 can promote cross-linking reactions and reduce VOC emissions, and comply with the requirements of the EU REACH regulations and China GB\/T 18582-2020 “Limits of Hazardous Substances in Interior Decoration Materials”. In addition, T12 has a certain biodegradability and can gradually decompose into harmless compounds in the natural environment, reducing long-term pollution to the environment. <\/p>\n The durability of furniture products is one of the important indicators that consumers pay attention to. By using T12 rationally, the product’s weather resistance, aging resistance and corrosion resistance can be significantly improved, and the product’s service life can be extended. For example, in the optimization of wood adhesive formulation, T12 can promote cross-linking reactions, enhance the adhesive bond strength and water resistance, and prevent degumming caused by moisture penetration. Experimental data show that after soaking wood adhesive with T12 catalyzed for 24 hours in water, the bonding strength remains above 90%, while products without catalysts have obvious degumming. In addition, T12 can promote the uniform distribution of anti-rust agent in the coating, enhance the anti-corrosion performance of the coating, and extend the service life of metal frame furniture. <\/p>\n The appearance quality of furniture products is directly related to consumers’ purchasing decisions. By using T12 rationally, the gloss, color stability and wear resistance of the product can be significantly improved, and the market competitiveness of the product can be enhanced. For example, during the construction of coatings and coatings, T12 can promote cross-linking reactions, form a denser molecular structure, enhance the coating’s weather resistance and UV resistance, and enable furniture to last longer in outdoor or humid environments or in humid environments The beauty and durability of time. Experimental data show that the coating using T12-catalyzed still maintains good gloss and color stability after two years of outdoor exposure, while products without catalysts showed obvious fading and peeling. <\/p>\n By rationally using T12, production costs can be effectively reduced and economic benefits of enterprises can be improved. For example, during the preparation of polyurethane foam, T12 can significantly increase the foaming speed and curing rate, shorten the production cycle, reduce the use time of the equipment and energy consumption. In addition, T12 can also play a catalytic role at lower temperatures, reduce the use of heating equipment, and further reduce production costs. According to the Journal of Industrial and Engineering Chemistry (2021), the production cost of polyurethane foam catalyzed using T12 is reduced by about 15% compared to products without catalysts, and the product quality has been significantly improved. <\/p>\n The application of organotin catalyst T12 in furniture manufacturing has achieved remarkable results, especially in improving product quality, reducing production costs and meeting environmental protection requirements. Through in-depth research and reasonable application of T12, furniture manufacturing companies can not only improve production efficiency, but also significantly improve the mechanical strength, durability, anti-aging performance and environmental protection performance of the products, thereby enhancing market competitiveness. <\/p>\n In the future, with the continuous advancement of technology and changes in market demand, the application prospects of the organotin catalyst T12 will be broader. On the one hand, researchers will continue to explore the application potential of T12 in more fields and develop more efficient and environmentally friendly catalyst products; on the other hand, enterprises will further improve the application effect of T12 through technological innovation and process optimization and promote furniture. Sustainable development of the manufacturing industry. <\/p>\n In order to better respond to future challenges, furniture manufacturing companies should pay close attention to industry trends and technological development trends, actively introduce advanced production equipment and management concepts, strengthen cooperation with scientific research institutions, promote the combination of industry, education and research, and jointly create more \ufffdCompetitive high-quality furniture products. At the same time, the government and industry associations should also increase support for the research and development of environmentally friendly catalysts, formulate more complete policies and regulations, guide enterprises to take the path of green development, and lay a solid foundation for the long-term development of the furniture manufacturing industry. <\/p>\n In short, the organic tin catalyst T12 has broad application prospects in furniture manufacturing and is expected to play an important role in more fields in the future, helping the furniture manufacturing industry achieve high-quality development. <\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":" Background of application of organotin catalyst T12 in …<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[15790],"gt_translate_keys":[{"key":"link","format":"url"}],"_links":{"self":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/54123"}],"collection":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/comments?post=54123"}],"version-history":[{"count":0,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/posts\/54123\/revisions"}],"wp:attachment":[{"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/media?parent=54123"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/categories?post=54123"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.newtopchem.com\/wp-json\/wp\/v2\/tags?post=54123"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
