Abstract

The peach paper bag is used to prevent the pesticide pollution, the erosion by wind and rain and the excessive sun shining of growing peach fruit. The paper for the bag is produced with bleached coniferous pulp in 30-50 % and waste paper pulp in 50-70 % as well as proper amount of dye, neutral size, paraffin emulsion, wet strength agent and stripping agent. The paper has a beating degree of 40-50 SR deg, wet weight of 4-6 g and unit area weight of 35-38 g/sqm. The paper bag is permeable, soft an waterproof.

Description

A kind of manufacture method of peach c 8 ultivation paper bag and product

The present invention relates to a kind of manufacture method and product of peach c 8 ultivation paper bag, can be used to do the peach fruit bag with the prepared finished paper of this method.

Along with the raising of people's living standard and the enhancing of environmental consciousness, the green fruit of natural and pollution-free green is just becoming the target of being pursued in people's production and the life.Peach is a kind of fruit variety that is loved by the people, and need spray insecticide in its growth course and resist insect pest and rotten, and agricultural chemicals will remain in to form on the peach fruit and pollute like this.On the other hand, cause and effect is real exposed fully, is exposed to the weather in its surface and becomes coarse, lacks the aesthetic feeling of elaboration fresh fruit.

The objective of the invention is to propose a kind of manufacture method and product of peach c 8 ultivation paper bag, the fruit bag of being made of the prepared finished paper of this method is enclosed within on the fruit of peach, 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 peach c 8 ultivation paper bag, this method comprises: slurrying pulping, making beating defibrination, furnishing, net part forming, press dewatering, dry, batch, the technical process of cutting and rewinding and packing, it is characterized in that the slurrying pulping is raw materials used and be 30-50% bleaching needle-point leaf pulp and 50-70% secondary stock; Beating degree is controlled at 40-50 ° of SR, weight in wet base 4-6g in the making beating; Adding with making the paper pulp weight ratio in the furnishing successively is 0.2-1: 100 coloring agent, 0.3-1.5: 100 neutral gum, 2-4: 100 paraffin emulsions, 2-4: 100 wet strength agents, 0.2-0.4: 100 remover; In the net part forming quantitatively at 35-38g/m ²Carry out font or pattern printing after batching.Can be 35-40% for bleaching needle-point leaf pulp wherein with scheme optimization, secondary stock be 55-65%; The making beating beating degree is at 44-48 ° of SR; Adding with making the paper pulp weight ratio in the furnishing is 0.8-1: 100 coloring agent, 1.2-15: 100 neutral gum, other composition is constant.

Technological process during the present invention produces is: wood pulp and secondary stock → hydraulic pulping → reserve pit → making beating defibrination → furnishing pond → paper machine material well → net part forming → press dewatering → dry → batch printing → 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 higher air permeability, moderate intensity and pliability, satisfied the respiration of fruit growth period, fruit surface and carpopodium do not wear and tear again; The 2nd, the light-proofness of paper bag is even, is fit to the painted requirement of peach, selects to have the dominant hue of the yellow of light fastness as peach c 8 ultivation paper bag, at the uniform black literal of the printed on both sides layout of paper, guaranteed that shading is even, but plucked a bag back peach fast colorizing, color and luster is evenly bright-coloured.The 3rd, have higher water proofing property and wet strength, can prevent spraying insecticide of peach growth period 2-4 time fully.The erosion of wind and weather can be resisted simultaneously, also broken bag can be do not caused even drench with rain for a long time.Every index with the made finished paper of this method is after testing: (1) is quantitative: 36g/m ²(2) dry strength 1.56KN/m; (3) wet strength: 0.67KN/m; (4) air permeability 8.2um/pa.s; (5) the positive 85S of surface smoothness; (6) look sun-proof degree 110 days is colour-fast; (7) water proofing property: 1.5 hours waterproof time; (8) friction do not fade, soft, not crisp.

Below with embodiment the present invention is done a step and sets forth.

Embodiment 1: bleaching needle-point leaf pulp with 35% and 65% secondary stock, put into reserve pit behind the hydraulic pulping, it is 46 ° of SR that economy-combat is milled to beating degree, put into the furnishing pond during weight in wet base 5g, adding with making the paper pulp weight ratio while stirring successively is 0.8: 100 coloring agent, 0.4: 100 neutral gum, 3: 100 paraffin emulsion, 4: 100 wet strength agent, 0.4: 100 remover are put into paper machine material well after mixing well, the quantitative 37g/m of control online ², through manufacture paper with pulp, batch, printing machine printed on both sides, cutting and rewinding make finished product.

Embodiment 2: according to the same process process of embodiment 1, every supplementary material proportioning is adjusted into following quantity, can produces the satisfactory finished paper of every index equally.(1) bleaching needle-point leaf pulp 50%; (2) secondary stock 50%; (3) coloring agent is 0.6: 100; (4) neutral gum is 1.2: 100; (5) paraffin emulsion is 2: 100; (6) wet strength agent is 2: 100; (7) remover is 0.2: 100.
