Abstract
The invention discloses a method for making corrugated base paper by rice straw unbleach pulp. The method comprises the following steps of: (I) beating the rice straw unbleach pulp, wherein a beating degree is controlled in a range of 28 to 320SR, and a wet weight is 3.2 to 3.8g; (II) beating waste paper pulp, wherein a beating degree is 28 to 300SR, and a wet weight is 2.5 to 2.8g; (III) according to a weight ratio of 7:3, mixing the rice straw unbleach pulp with the waste paper pulp, feeding a mixture to a paper machine and making the mixture into the corrugated base paper. According to the method disclosed by the invention, resource effective recycling of rice straws is achieved. Compared with corrugated base paper made of pure waste paper pulp, the corrugated base paper made by the method has a higher performance index, is obviously improved on the aspects of ring crush compression resistance, a fracture length and a flat compression index, and can be used as high-strength corrugated paper.
Description
Technical field
The present invention relates to a kind of rice straw natural color pulp to manufacture paper with pulp the method for fluting medium.
Background technology
Corrugated board (case) is the environmental type packaging product that the whole world is generally acknowledged. But the enhancing day by day along with people's environmental protection ideas, add the worsening shortages of the day by day deficient of Global Forests resource and water and soil resources, needed for producing carton paper using, the felling of timber is all increasingly restricted in many countries, causes the source of corrugated case industry lumber fibre to be severely impacted.
According to State Statistics Bureau's relevant statistics, within 2014, national Oryza glutinosa sown area is 30,310,000 hectares, Oryza glutinosa total output is 1.72 hundred million tons, known according to the estimation algorithm (1 kilogram of Oryza glutinosa about produces 1.1 kilograms of straws) of crop yield Yu straw, China there are about the Oryza glutinosa straw of 1.89 hundred million tons every year, and annual reserves are extremely abundant.
The main way of the process of current Oryza glutinosa straw has: chopping and returning, on-site incineration, biomass power generation, pulping and paper-making etc. Chopping and returning affects the sowing in the coming year, has increased the weight of pest and disease damage; Biomass power generation is owing to being subject to the impact of haul distance, and beyond the increase at double of transportation radius cost of transportation, generating is not made money; On-site incineration serious environment pollution, is prohibited by country, can play the effect of resource reutilization hence with Oryza glutinosa straw pulping and paper-making.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of rice straw natural color pulp is manufactured paper with pulp the method for fluting medium.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
Rice straw natural color pulp is manufactured paper with pulp the method for fluting medium, comprises the steps:
(I) rice straw natural color pulp being pulled an oar, beating degree controls at 28-320SR, weight in wet base 3.2-3.8g;
(II) secondary stock being pulled an oar, beating degree controls at 28-300SR, weight in wet base 2.5-2.8g;
(III) by weight for 7:3, rice straw natural color pulp and secondary stock being mixed, upper paper machine, manufacture paper with pulp into fluting medium.
Further, described rice straw natural color pulp obtains by comprising the following steps:
(1) rice straw is cut into material section;
(2) material section first send decatize storehouse to steam in advance, is re-fed into even steam device and carries out steaming and decocting, adds the potassium hydroxide of 1.5��2%, the ammonium sulfite of 1.2��1.5%, the sodium tripolyphosphate of 1.2��1.5% during steaming and decocting by material section weighing scale;
(3) material after steaming and decocting send double; two spiral shell stalk fiberizer to carry out stranding to rub sub-wire, and pulp washing obtains natural color pulp.
Further, the material segment length 30-40mm of step (1).
Further, steaming and decocting solid-liquid ratio is 1:5, and temperature is 120��125 DEG C, and the time is 55��60min.
Further, the material elder generation spiral dehydration after steaming and decocting, then give double; two spiral shell stalk fiberizer to carry out stranding to rub sub-wire.
Beneficial effects of the present invention:
1, the resource achieving Oryza glutinosa straw effectively recycles.
2, compared with the fluting medium that pure secondary stock is manufactured paper with pulp, the present invention make fluting medium there are higher performance indications, ring crush intensity, fracture length peace end finger number be improved significantly, can be used as high-strength corrugated paper.
3, pulping efficiency is high, and pulp yield can reach 75��80%, and fiber quality is good, and average fiber length reaches 3.26um, and length and width ratio is big.
4, the waste water b/c ratio that system produces is high, can reach about 0.5, and very easily biochemical, water processes the way that can adopt biological treatment, specifies direction for paper-making zero discharge.
