Abstract

The invention relates to a process for improving packaging paper pulp, which comprises the following steps: making paper pulp from herbaceous raw materials; removing impurities which are 15-20 per mill of the weight of the finished product which is the dry paper pulp and have a length-width proportion of 1.1:1-1.5:1 and a length of 0.05-0.08mm from the paper pulp; adding multi-carbon fatty alcohol, sodium hydroxide, sodium silicate and hydrogen peroxide into the paper pulp, wherein the multi-carbon fatty alcohol is 2.0 per mill of the weight of the finished product which is the dry paper pulp, the sodium hydroxide is 8 per mill of the weight of the finished product, the sodium silicate is 2 per mill of the weight of the finished product, and the hydrogen peroxide is 20 per mill of the weight of the finished product; and removing impurities which are 5per mill of the weight of the finished product which is the dry paper pulp and have a length-width proportion of 1.1:1-1.5:1 and a length of 0.05-0.08mm from the paper pulp. The packaging paper pulp is a herbaceous paper pulp which can replace the wood paper pulp, can be particularly used in the field of paper packaging industry, has considerable strength and good appearance and handfeel and is white in color.

Description

Packaging paper pulp improve technology

Technical field

The present invention is about a kind of pulp technology, the paper pulp that particularly can be processed by herbaceous stem materials such as reed, stalks.

Background technology

Existing common paper pulp can be categorized into wood pulp that the high megaphanerophyte material of serving as reasons processes and the herbaceous stem paper pulp of being processed by herbaceous plant.As everyone knows, the paper of wood pulp made has the feel and the outward appearance of good serviceability and exchange, and herbaceous stem paper pulp is then more inferior relatively.

But from the responsibility of environmental protection, each industrial circle should reduce the felling to trees, especially paper industry as far as possible.Therefore paper industry turns to and adopts the raw material of the annual herbaceous plant that all regularly grows as papermaking.

Purpose for environmental protection; Do not reduce simultaneously the various demands of people as far as possible to paper quality; Therefore a kind of herbaceous stem paper pulp that can substitute wood pulp need be provided, especially it be utilized in the papery packaging industry, both have suitable intensity to reach; Have outward appearance and feel preferably again, and have whiter background color.

Summary of the invention

For solving the problems of the technologies described above, improve people's living environment and natural environment, a kind of for this reason packaging paper pulp of the present invention improve technology, it comprises: mainly utilize the herbaceous stem raw material to make paper pulp; Remove from said paper pulp relatively that the weight of its finished product dry pulp is 20 ‰ to 15 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter; The weight that in said paper pulp, adds relative its finished product dry pulp is 2.0 ‰, 8 ‰, 12 ‰, 20 ‰ many carbon fatty alcohols, NaOH, waterglass, hydrogen peroxide solution; Remove from said paper pulp relatively that the weight of its finished product dry pulp is 5 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter.

This paper pulp can obtain to substitute the use of wood pulp, particularly utilizes it at the papery packaging industry.

The specific embodiment

The present invention relates to a kind of technology of improving of packaging paper pulp, it comprises:

Step 1: mainly utilize the herbaceous stem raw material to make paper pulp; Wherein said herbaceous stem raw material comprises: stalk, reed, sugarcane, bamboo or flax also can be the mixture combinations that also has at least two kinds of above-mentioned raw materials.

Step 2: remove from said paper pulp relatively that the weight of its finished product dry pulp is 20 ‰ to 15 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter; Said step 2 is to carry out through filtration, screening, classification or based on the method for weight difference.

Step 3: the weight that in said paper pulp, adds relative its finished product dry pulp is 2.0 ‰, 8 ‰, 12 ‰, 20 ‰ many carbon fatty alcohols, NaOH, waterglass, hydrogen peroxide solution.

Step 4: remove from said paper pulp relatively that the weight of its finished product dry pulp is 5 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter.

Through the paper pulp that disclosed method obtains, the paper material that can utilize comparatively environmental protection is as raw material production paper pulp.More can obtain to have the characteristic that substitutes existing wood pulp, for example its texture and intensity, with and whiteness, for example can arrive 60% whiteness.

Therefore realized providing a kind of purpose that can substitute the herbaceous stem paper pulp of wood pulp, especially it has been utilized in the papery packaging industry, both had suitable intensity, had outward appearance and feel preferably again, and have whiter background color to reach.

Claims

A packaging paper pulp improve technology, it is characterized in that:

Step 1: mainly utilize the herbaceous stem raw material to make paper pulp;

Step 2: remove from said paper pulp relatively that the weight of its finished product dry pulp is 20 ‰ to 15 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter;

Step 3: the weight that in said paper pulp, adds relative its finished product dry pulp is 2.0 ‰, 8 ‰, 12 ‰, 20 ‰ many carbon fatty alcohols, NaOH, waterglass, hydrogen peroxide solution;

Step 4: remove from said paper pulp relatively that the weight of its finished product dry pulp is 5 ‰, Aspect Ratio is between between 1.5: 1 to 1.1: 1 and the impurity of length between 0.05 to 0.08 millimeter.
2. packaging paper pulp as claimed in claim 1 improve technology, it is characterized in that: said step 2 is to carry out through filtration, screening, classification or based on the method for weight difference.
