Embodiment 1

[0015] Embodiment 1 produces high-strength moisture-proof bobbin paper

[0016] The process is as follows:

[0017] (1) Ingredients: mix waste paper with heavy wax content and waste paper with light wax content as raw materials, so that the average wax content of the total raw materials is 3-8% by weight;

[0018] (2) Crushing: crush the matched raw materials into small pieces of paper with a diameter of less than 5 cm, so as to facilitate beating;

[0019] (3) Beating: Add the paper pieces into the beater with hot water added in advance, beat with the beater, while beating and heating to 65°C above the melting point of the paraffin to melt the paraffin, through the high-speed operation and stirring of the beater, make The paper fiber fully absorbs the melted polymer paraffin in the paper fiber, and beats the small paper strips into a rough pulp with a degree of disintegration of 16-26 degrees, and the pulp concentration is 4%-7% (wt%);

[0020] (4) Squeezing: Use a high-con...

Embodiment 2

[0027] Example 2 Production of high-strength moisture-proof corrugated paper

[0028] The process is as follows:

[0029] (1) Ingredients: mix waste paper with light wax content and waste paper with heavy wax content as raw materials, so that the average wax content of the total raw materials is 3-12% by weight;

[0030] Other steps (2) to (8) are the same as in Example 1. Then use the paper machine to produce high-strength moisture-proof corrugated paper and cardboard paper according to the conventional papermaking process.

[0031] The high-strength moisture-proof corrugated paper produced has good moisture-proof effect and is widely used in electrical appliances, electronics, fruit and vegetable preservation and various product packaging. The production cost is 400-600 yuan / ton lower than that of high-strength corrugated paper of the same quality.

Embodiment 3

[0032] Embodiment 3 produces moisture-proof kraft paper

[0033] The process is as follows:

[0034] (1) Matching waste paper with light wax content and waste paper with heavy wax content as raw materials, so that the average wax content of the total raw materials is 7-30% by weight;

[0035] Other steps (2) to (8) are the same as in Example 1. Then use the paper machine to produce high-strength moisture-proof kraft paper according to the conventional papermaking process.

[0036] The cost of kraft paper produced by this method is 800-1000 yuan / ton lower than traditional recycled kraft paper, 1500-1800 yuan / ton lower than waxed recycled kraft paper, and 1400-1600 yuan / ton lower than laminated recycled kraft paper.

Abstract

The present invention discloses papermaking process with wax-containing waste paper. The papermaking process with wax-containing waste paper features the pulping process includes the steps of: compounding material, crushing, beating, extruding, washing, grinding and sieving to eliminate slag. The papermaking process with wax-containing waste paper as material has the effects of reusing waste paper resource and protecting environmental.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a process for making paper from waste paper containing wax. Background technique [0002] Moisture-proof kraft paper, moisture-proof corrugated paper, wax-impregnated high-strength corrugated paper, moisture-proof cardboard paper, super calendered paper, fruit bagging paper, moisture-proof bobbin paper and sealing paper for cement packaging all contain a certain amount of paraffin wax. This kind of waxy waste paper is not easy to decompose naturally, so the used waste paper is easy to pollute the environment. Contents of the invention [0003] The purpose of the present invention is to provide a method for making paper by using waxy waste paper, through recycling the waxy waste paper, to achieve resource reuse and solve the environmental pollution problem caused by waxy waste paper. [0004] The present invention adopts the following technical scheme: a method for making paper by us...
