Embodiment 1

[0006] Embodiment 1: First, the annual fennel stalk is cut into a raw material with a length of 20 mm with a grass cutter, and then the cut raw material and water are added to water at a mass ratio of 1:20, and steamed at 200° C. for 20 minutes; Take out the raw materials, use the refiner to grind the raw materials into pulp, control the beating degree of the pulp after grinding to 35 degrees, and finally pass the pulp through the screener to remove coarse fibers and other impurities, and send the pulp into the paper machine High-strength corrugated paper can be obtained by copying.

Embodiment 2

[0007] Embodiment 2: First, the annual fennel stalk is cut into raw materials with a length of 30 mm with a grass cutter, and then, the cut raw materials and water are added to water at a mass ratio of 1:15, and boiled at 100° C. for 180 minutes; Take out the raw materials, use the refiner to grind the raw materials into pulp, control the beating degree of the pulp after grinding to 30 degrees, and finally pass the pulp through the screener to remove coarse fibers and other impurities, and send the pulp into the paper machine High-strength corrugated paper can be obtained by copying.

Embodiment 3

[0008] Embodiment 3: First, the annual fennel stalk is cut into raw materials with a length of 25 mm with a grass cutter, then, the cut raw materials and water are added to water at a mass ratio of 1:10, and steamed at 150° C. for 80 minutes; Take out the raw materials, use the refiner to grind the raw materials into pulp, control the beating degree of the pulp after grinding to 28 degrees, and finally pass the pulp through the screener to remove coarse fibers and other impurities, and send the pulp into the paper machine High-strength corrugated paper can be obtained by copying.

Abstract

A preparation method of high-strength corrugated paper. First cutting the common fennel fruit stem into raw materials which length is 20-40 mm, then, adding the raw materials into water which weight ratio is 1:4-20, boiling 20-180 minutes under 100-200 deg.C; putting out the raw materials, milling the raw materials into pulp with pulp grinder, the beating grade of pulp after controlled milling is 25 - 35 degrees, at last screening the pulp through pulp screen, removing coarse fibers and other impurities, sending the pulp into paper machine then preparing the high-strength corrugated paper. Due to the common fennel fruit contains large amounts of fiber, it is the good raw material for paper making. The invention makes high-strength corrugated paper using common fennel fruit stem, it not only improves the use value of common fennel fruit stem and saves energy, but also avoids the environmental pollution caused by burning effectively.

Description

technical field [0001] The invention belongs to the field of pulp and papermaking, and in particular relates to a preparation method of high-strength corrugated paper. Background technique [0002] Cumin is an annual plant that is grown all over the country. People mainly collect its ripe fruit, because the dry ripe fruit tastes pungent and warm, and has the functions of dispelling cold and relieving pain, regulating qi and regulating the stomach. It is often used for cold colic, abdominal pain, testicular deflection, dysmenorrhea, cold pain in the lower abdomen, abdominal pain, vomiting and diarrhea due to lack of food, testicular hydrocele, etc. Therefore, it has high medical and health care value. Yet, although the fruit of cumin has been fully utilized, its stem is not fully and effectively utilized at present, and now general stem is either burned as firewood, or is directly buried back in the ground as fertilizer. Contents of the invention [0003] The object of th...
