研究了各湿部单因素对ＥＭ－ ５０５ 型分散松香胶施胶效果的影响。结果表明，根据浆料种类及纸种的施胶要求，ＥＭ－ ５０５ 型分散松香胶的用量控制在０ ．３ － ０ ．８ ％ 之间为宜；在ｐＨ 值为４ ．０ － ５ ．０ 的范围内，均能获得较好的施胶效果，若ｐＨ 值超过５ ．０ ，施胶度下降较快；打浆对施胶影响很大，总的趋势是随着打浆度的增加，施胶度逐渐下降。
The effect of single wetting factor on the sizing effect of EM-505 dispersed rosin gum was studied. The results showed that the dosage of EM-505 dispersed rosin gum was controlled at 0 according to the type of pulp and the sizing requirements of paper. 3 - 0. 8% between the appropriate; at a pH of 4. 0 - 5. 0 range, can get better sizing effect, if the pH value exceeds 5. 0, sizing degree decreased rapidly; beating a great influence on sizing, the general trend is with the increase of beating degree, sizing degree gradually decreased.
