Problems solved by technology

[0004] In the existing papermaking process, usually after mixing different pulps after beating, fillers are directly added, and then other additives are added, and the pulps after beating are not separated, so that fiber materials with different lengths are mixed in Together with fillers, it can neither effectively play the advantage of long fibers that can improve the strength of paper, nor can it fully play the role of short fibers with better adsorption

Embodiment 1

[0035] Plant petal / leaf standard color comparison paper, including short fibers less than or equal to 180 microns and long fibers with a length greater than or equal to 180 microns, the width of the long and short fibers is 4.2-6.5 microns; the tightness of the color comparison paper is 0.618~0.632g· cm -3 , the tear index is 4.92-5.08mN m 2 g -1 . By limiting the length and width of the long and short fibers in the prepared colorimetric paper, the present invention can give full play to the effect of the long fibers, that is, the short fibers can absorb more fillers to improve the retention rate of the fillers, and the long fibers can improve the strength of the colorimetric paper. , and by setting the value of the long and short fibers above, it is beneficial to improve the hydrophobicity of the paper, and the final tightness of the paper is 0.618~0.632g·cm -3 , the tear index is 4.92-5.08mN m 2 g -1 The paper has excellent appearance quality, high physical index, color...

Embodiment 2

[0037] The preparation technology of plant petal / blade standard color comparison paper comprises the following steps:

[0038] 1) Preparation of pulp raw materials:

[0039] a. Material preparation: dry the corn stalks, separate the husks to get the husks, and cut the husks into pieces;

[0040] b. Pretreatment: cook the straw in the cooker, the solid-to-liquid ratio is 1:4, and heat the cooking additives. The cooking time is 2.5 hours. The heating time during the cooking process is 75 minutes. ℃ small outgassing, additives are NaOH and C 14 h 8 o 2 、C 19 h 17 N 3O 、H 2 o 2 Composition, the amount of NaOH is 10.4% of the weight of the cooking liquid used for cooking, C 14 h 8 o 2 The dosage is 1.04% of the weight of straw used for cooking, C 19 h 17 N 3O The dosage is 0.04% of the weight of straw used for cooking, H 2 o 2 The dosage is 2% of the weight of straw used for cooking. During the cooking process, the additives can promote the rapid degradation of the...

Embodiment 3

[0050] Embodiment 3: the preparation technology of plant petal / blade standard color comparison paper comprises following preferred steps:

[0051] 1) Preparation of pulp raw materials:

[0052] a. Material preparation: dry the corn stalks, separate the husks to get the husks, and cut the husks into pieces;

[0053] b. Pretreatment: cook the straw in a cooker with a solid-to-liquid ratio of 1:6, and heat the cooking additives for 3 hours. During the cooking process, the heating time is 80 minutes. Small outgassing, the additive consists of NaOH and C 14 h 8 o 2 、C 19 h 17 N 3O 、H 2 o 2 Composition, the amount of NaOH is 12% of the weight of the cooking liquid used for cooking, C 14 h 8 o 2 The dosage is 1.08% of the weight of straw used for cooking, C 19 h 17 N 3O The dosage is 0.05% of the weight of straw used for cooking, H 2 o 2 The dosage is 2% of the weight of straw used for cooking;

[0054] c. Bleaching and cleaning: the straw pulp is bleached by CHE thr...

Abstract

The invention discloses standard colorimetric paper for plant petals / leaves. The standard colorimetric paper comprises short fibers with the length less than or equal to 180 microns and long fibers with the length greater than or equal to 180 microns, and the widths of the long fibers and the short fibers are 4.2-6.5 microns; the compactness of the colorimetric paper is 0.618-0.632 g.cm<-3>, the tearing index of the colorimetric paper is 4.92-5.08 mN.m<2>.g<-1>. According to the standard colorimetric paper for the plant petals / leaves, the standard colorimetric paper is prepared from maize straw, the contrast accuracy is high, use is convenient, the area of a contrast can be estimated, and the prepared colorimetric paper has both high appearance quality and physical index to achieve the standard of high quality culture paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, in particular to a plant petal / leaf standard color comparison paper. Background technique [0002] Color comparison paper is to reflect the colors that exist in nature on paper, and is used for color selection, comparison, and communication. It is a tool for achieving uniform standards within a certain range of colors. There are defects in the estimation of the area of ​​the control object, and the paper quality of the existing color comparison paper is not high, and the color comparison paper is often damaged after repeated use. [0003] The raw materials of my country's paper industry are still in the transition stage from "grass-based" to "wood-based". For a long period of time in the future, non-wood fiber raw materials will continue to play an important role in my country's paper industry. Our current straw pulp manufacturers have changed their former backward appearance, adopt advanced...
