Abstract

The grape and mango paper bag is used to prevent the pesticide pollution and the erosion by wind and rain of growing grape and mango fruit. The bag paper is produced with bleached coniferous pulp in 50-80 % and bleached broad-leaved pulp in 20-50 5% as well as whitener, rosin size, aluminium sulfate, paraffin solution and wet strength agent. The paper has a beating degree of 25-40 SR deg, wet weight of 4-8 g and unit area weight of 35-38 g/sqm. The paper bag is permeable, waterproof and soft and is used for grape, mango and other plant.

Description

A kind of manufacture method of grape cultivation paper bag and product

The present invention relates to a kind of manufacture method and product of grape cultivation paper bag, can be used to manufacture the grape cultivation paper bag, can also be used to manufacturing mango, balsam pear etc. and educate the fruit paper bag with this method products made thereby.

In the production and life of modern society, free of contamination " pollution-free food " more and more is subjected to people's favor.Grape in the fruit, mango etc. need be sprayed insecticide in growth course and be prevented insect pest and rotten, and residues of pesticides form pollution on fruits such as grape, mango like this.Fruit such as grape, mango is because of being exposed to the outside on the other hand, and its surface color dimness lacks aesthetic feeling.

The objective of the invention is to propose a kind of manufacture method and product of grape cultivation paper bag, the fruit bag of being made of the prepared finished paper of this method is enclosed within on the fruits such as grape, mango, both prevented the erosion pollution of agricultural chemicals and wind and rain, guarantee the needs of fruit growth period growth conditions again, overcome the defective of prior art.

Technical scheme of the present invention is achieved in that a kind of manufacture method and product of grape cultivation paper bag, this method comprises: slurrying pulping, making beating, furnishing, net part forming, press dewatering, oven dry, top sizing, batch, the technical process of cutting and rewinding, it is characterized in that the raw materials used bleached hardwood pulp of slurrying pulping for the bleaching needle-point leaf pulp of 50-80% and 20--50%; In the furnishing additive therefor with make the paper pulp weight ratio and be: 0-0.4: 100 brightening agent, 1.5-2.5: 100 gum rosin, 4-6: 100 aluminum sulfate, 1.5-2.5: 100 paraffin wax solution, 2-4: 100 wet strength agent; Beating degree in the making beating is controlled at 25-40 ° of SR, and weight in wet base is controlled at 4-8g; Net part forming quantitatively at 35-38g/m ²Preferred version wherein can be adjusted to bleaching needle-point leaf pulp and the 30-40% bleached hardwood pulp of 60-70%; Beating degree is 30-35 ° of SR in the making beating, 1.8-2.4: 100 gum rosin, 1.8-2.3: 100 paraffin emulsion, other composition is constant.

The technological process aborning of this method is:

That wood pulp → hydraulic pulping → reserve pit → making beating defibrination → furnishing pond → paper machine material well → net part forming → press dewatering → oven dry → surface is coated with is cured → batch → cutting and rewinding → packing.

Advantage and good effect that the present invention is had compared with the prior art are: owing to adopt technique scheme, make that made finished paper one is to have the required air permeabilities of fruit growth period such as suitable grape, mango, has satisfied the fruits respiratory effect; The 2nd, finished paper has better waterproof and wet strength, with this finished paper make educate fruit paper bag be fruit baggings such as grape, mango after, can prevent because of spraying insecticide, and can resist autumns in summer two monsoon rain erosion the pollution of fruit; The 3rd, the finished paper smooth surface, pliability is good, has alleviated the friction of paper bag to fruit surfaces such as grape, mango, has guaranteed the glossiness of fruit surface.Through the made finished paper sampling Detection of this method, its every index is: 1, quantitative: 38g/m ², 2, air permeability 10.8um/pa.s, 3, wet strength: 1.0KN/m, 4, dry strength: 2.2KN/m, 5, whiteness 85%, 6, single face smoothness: 86S, 7, water proofing property: 2.0 hours waterproof time, boiling water pearl, sticking water; 8, softness, not crisp.

Following examples are further elaborated the present invention.

Embodiment 1: a kind of manufacture method of grape cultivation sack kraft paper and product, after bleaching needle-point leaf pulp according to 70% and 30% bleached hardwood pulp prepare, put into reserve pit through the hydraulic pulping processing, through being polished to beating degree at 30 ° of SR, put into the furnishing pond during weight in wet base 6g left and right sides, adding with making the paper pulp weight ratio in the furnishing pond is 2: 100 brightening agent, 1.5: 100 gum rosin, 4: 100 aluminum sulfate, 2.5: 100 paraffin emulsion, 2.5: put into paper machine material well behind 100 the wet strength agent furnishing, control quantitative 36g/m ², manufacture paper with pulp through paper machine, according to 2g/m ²Paraffin emulsion carries out the surface and is coated with curedly, batches, cutting and rewinding is the finished product grape cultivation paper bag.

Embodiment 2: according to embodiment 1 same process, the ratio of major ingredient, auxiliary material is adjusted into: (1) bleaching needle-point leaf pulp: 80%; (2) bleached hardwood pulp: 20%; (3) brightening agent: 0.2: 100; (4) gum rosin: 2: 100; (5) aluminum sulfate: 5: 100; (6) paraffin emulsion: 2.0: 100; (7) wet strength agent: 3: 100, the paraffin emulsion surface was coated with thick 2g/m ²Can make the satisfactory finished paper of every index equally.
