    Except for < a href= "http:// www.91se91.com/news/index_c.asp" > vegetable tanning agent > /a > aldehyde tanning agent, the development of metal binding tanning agent is also of great significance for improving tanning effect. P At the Tenth National Leather Chemicals Symposium, Sichuan University shared the latest research progress in the application of zirconium, titanium, aluminum and iron polymetallic tanning agents and their application in tanning of goats upper leather. < /p >
    According to the introduction of P, the purpose of the research is to develop a new chrome free multi metal complex tanning agent to meet the requirements of ecological tanning agent and study its tanning properties. < /p >
    < p > the research is based on the application of iron zirconium aluminum compound tanning agent and its tanning system to < a href= "http:// www.91se91.com/news/index_c.asp" > Goat Shoe < /a > surface leather. The physical and mechanical properties, sensory properties and chemical properties of tanned leather are studied, compared with conventional chrome tanning leather, and compared with the industry standard of China's light industry on upper leather. < /p >
    < p > analysis of the sensory properties of leather shows that the comprehensive score of iron zirconium aluminum tanning leather is slightly lower than that of conventional chrome tanned leather, and the 3 aspects of softness, fullness and grain quality are lower. < /p >
    < p > but the degree of elasticity of polymetal matching < a href= "http:// www.91se91.com/news/index_c.asp" > tanning /a > is higher than that of conventional chrome tanning leather. The comparative study of two kinds of process system from economic cost shows that the cost of producing the unit area of iron zirconium aluminum complex tanning system is obviously lower than the unit cost of chrome tanning system. < /p >
    < p > but the significance of this research is to eliminate the pollution of chromium to the environment and solve the problem of resource utilization of tannery solid waste, so as to truly realize ecological leather making. < /p >
