摘要:为了人类与自然和谐发展，适当降低纸张白度势在必行。通过降低纸张白度，可以降低造纸用浆料白度和增白剂的用量，实现节能降耗；降低浆料白度可以大幅度地降低制浆过程中化学品的消耗、提高制浆原料的利用率、减轻环境污染、提高化机浆的配比，降低纸产品成本，保护人类视力。

Abstract:In the green and low carbon era, in order to realize the harmonious development between human being and nature, lowering down the whiteness of the paper products is imperative. Because lowering the paper whiteness can decrease the whiteness of the materials used for producing the papers and decrease the dosage of brightener, therefore can realize energy saving; on the other hand, to lower the pulp whiteness can decrease the consumption of chemicals and increase the pulp yield and reduce pollution; it also can increase the possibility of higher mechanical pulp usage therefore to lower the cost of paper and protect human eyesight.
