順酐廠家
  It is common that coking benzene is used as raw material with poor color thermal stability in China. Maleic anhydride in Shandong Province is common at 140 ° C and 70 - 80 ° C in 2 hours, with a severity of about 200 ° C (APhA). The stabilizer for maleic anhydride production from coking benzene, especially its advantages, is incomparable to the stabilizer introduced by SD Company. The effect is that platinum cobalt is less than 20 (usually 15 × 3) in 2 hours at 140 ℃. The strengthening test is more obvious at 180 ℃ for 1 hour (2 hours at 180 ℃, under the living condition, generally not affected by maleic anhydride) "= 40 ?. The cost is low: 0.3 yuan / ton maleic anhydride. The price of maleic anhydride with stabilizer in chemical plant is 100-300 yuan / ton higher than that without stabilizer, and the effect is far worse than that of stabilizer. The economic benefits are obvious. The addition of maleic anhydride heat stabilizer can be used to manufacture high-grade resin and stabilize the product quality. The quantity of ecru heat stabilizer is better than that of imported heat stabilizer in order to improve the competitiveness of products and directly improve the economic benefits.
