Abstract
Regarding the issue of poor oil proof effect of wheat straw high yield pulp under the economic dosage of fluorine-containing oil proof agent,oxygen delignification on wheat straw high yield pulp was carried out and obtained a series of wheat straw pulp with different Kappa val-ue.The influence of lignin content in wheat straw pulp on the effectiveness of fluorine-containing oil proof agent was explored.From the re-search results,it could be seen that the lignin content in wheat straw pulp had a significant impact on the effect of oil proof agent.At 1%mass fraction(relative to oven-dried pulp)oil proof agent dosage,when the Kappa value of wheat straw pulp decreased to less than 50.0,the paper had a preliminary oil-proof effect;when the Kappa value of wheat straw pulp was in the range from 30.0 to 50.0,the oil proof level of the pa-per gradually increased with the reduction of the Kappa value;when the Kappa value of the pulp dropped to less than 30.0,the oil proof level of pape reached the highest level(level 7).The Owens-Wendt-Rabel-Kaelble(OWRK)method was used to analyze the surface free energy of paper.As lignin was removed from the wheat straw pulp,the surface free energy of the paper continued to decrease,while the polarity ratio continued to increase.This indicates that the removal of lignin is beneficial for improving the oil resistance of the paper.The lignin content in wheat straw pulp can also affect the adding amount of oil proof agent.Under the given oil repellent requirements,the lower the Kappa value of the wheat straw pulp,the less oil proof agent is required.关键词
