Abstract

The fruit bag is used to prevent the pesticide pollution and the erosion by wind and rain of growing fruit. The double-layered fruit bag is produced through separate pulp making of outer layer and the inner layer, composition, pressing, stoving, waterproof surface glue treatment and other technological steps. The double-layered fruit bag may be used for apple, pear and other fruits and has the advantages of good permeability, softness and waterproof property, and its use can prevent erosion of pesticide and wind and rain and make fruits lustrous.

Description

A kind of manufacture method of outer paper of double layer fruit bag and product

The present invention relates to a kind of manufacture method and product of outer paper of double layer fruit bag.

In the production and life of modern society, free of contamination natural green fruit has been subjected to people's welcome, and its economic worth, nutritive value have all had qualitative leap.But as to preventing pollution by pesticides, erosion by wind and rain, and strengthen the major issue that fruit surface gloss is the development of fruit industry.Being placed in the fruit whole production phase with fruit bag is solution to this problem, but existing paper does not still have required every performance indications.

Purpose of the present invention is exactly manufacture method and the product that proposes a kind of outer paper of double layer fruit bag, the fruit bag of being made of the obtained finished paper of this method, mixing suitable inner bag is placed on the fruit, both prevented the erosion pollution of agricultural chemicals and wind and rain, guaranteed the condition of fruit growth again, it is bright-coloured to have strengthened its surperficial gloss, has overcome

The defective of prior art.

Technical scheme of the present invention is achieved in that a kind of manufacture method and product of outer paper of double layer fruit bag, this method comprises: the slurrying pulping, the making beating defibrination, furnishing, conical refiner is handled, flow box is handled, net part forming, press dewatering, oven dry, the anti-water treatment of surface glue, oven dry, batch, the technical process of cutting and rewinding, it is characterized in that above technical process is by A, B two parts raw material is pressed same process flow and is handled before press dewatering, wherein A partly is outer raw material, mix by 30-70% hardwood pulp and 30-70% softwood pulp, behind the hydrabrusher size degradation, put into reserve pit, be polished to 30-50 ° of SR beating degree through beater and mill, put into the furnishing pond behind the weight in wet base 2-7g, in the furnishing pond by with make the paper pulp weight ratio for adding 0-4: 100 coloring agent, 0.5-1.5: 100 gum rosin, 2-5: 100 paraffin wax glue, 2-6: 100 aluminum sulfate, 3-5: 100 wet strength agent, 0-2: 100 softener, put into the outer paper stock well of paper machine after mixing, again through conical refiner, flow box, net part forming quantitatively is controlled at 25-32g/m2; B partly is the internal layer raw material, by not bleaching needle-point leaf pulp and the mixing of 30-70% bleached hardwood pulp of 30-70%, behind the hydrabrusher size degradation, put into reserve pit, be polished to 40-65 ° of SR beating degree through beater and mill, put into the furnishing pond behind the weight in wet base 4-8g, adding with making the paper pulp weight ratio in the furnishing pond is 6-12: 100 black dye, 0.5-1.5: 100 gum rosin, 2-5: 100 paraffin wax glue, 0.1-1: 100 removers, 2-6: 100 aluminum sulfate, 3-5: 100 wet strength agent, 0-2: 100 softener, put into paper machine internal layer paper stock well after mixing, again through conical refiner, flow box, net part forming, quantitatively be controlled at 18-25g/m ²Will be through A, B two parts material unipress of above PROCESS FOR TREATMENT, process, oven dry, the anti-water treatment of surface glue then, dry, batch, cutting and rewinding makes finished product.The technological process of production of the present invention is:

Advantage and good effect that the present invention is had for the prior art comparison are: owing to adopt technique scheme, making made finished paper one is that paper intensity, air permeability and flexibility are good, both guaranteed the respiration of fruit growth period, do not wear and tear carpopodium again and cause the fruit.The 2nd, have higher water proofing property and wet strength, can resist the spray medicine and the wind and weather of fruit growth period 8-12 time, make paper surface boiling water pearl and sticking water, can be because of wet water broken bag yet.The 3rd, the many applicabilities of pattern are strong, and multiple color such as that its skin can have is pale yellow, light green, white can flash back the sunlight, and can adapt to the requirement of different fruit kinds again, and internal layer paper is black or other light color, has adapted to the different needs of various fruits to light-proofness.Every index of the made finished paper of the present invention is as follows after testing: (1) is quantitative: 50g/m ²(2) shades of colour such as white, pale yellow, light green; (3) air permeability: 8.5um/pa.s; (4) dry strength: 2.3KN/m; (5) wet strength 1.1KN/m; (6) soft, not crisp, paper boiling water pearl, sticking water.

Below with embodiment the present invention is further elaborated:

The manufacture method of embodiment 1, a kind of outer paper of double layer fruit bag and product, this method is: A partly is outer raw material, 80% the bleached hardwood pulp that does not float softwood pulp and 20% is dissolved, behind size degradation, put into reserve pit, the mill polishing is to 45 ° of SR, put into the furnishing pond during weight in wet base 3.8g, adding with making the paper pulp weight ratio is 2: 100 Yellow colorant, 1.1: 100 gum rosins, 1.2: 100 paraffin wax glue, 4.5: 100 aluminum sulfate, wet strength agent dyed furnishing after puts into the outer paper stock well of paper machine at 3: 100; Internal layer 40% with the B part does not float softwood pulp and bleached hardwood pulp mixing simultaneously, behind size degradation, put into reserve pit, economy-combat is milled to 55 ° of SR of beating degree, put into the furnishing pond during weight in wet base 3.5g, add with make 6: 100 black dye of paper pulp weight ratio, 1.1: 100 gum rosin, 1.2: 100 paraffin wax glue, 0.1: 100 remover, 4.5: 100 aluminum sulfate, 3: 100 wet strength agent, the furnishing that dyes after put into paper machine internal layer paper stock well.A, B two parts are carried out unipress, oven dry, top sizing, oven dry, outer paper through two net paper machines control quantitative 28g/m ², internal layer paper is controlled quantitative 20g/m ²Manufacture paper with pulp, through batching, cutting and rewinding makes finished product again.

Embodiment 2, according to embodiment 1 described technical process, proportioning raw materials is adjusted into: the outer raw material of A part is 60% hardwood pulp and 40% softwood pulp, B part internal layer raw material is 45% not float softwood pulp and 55% bleached hardwood pulp, can make the satisfactory finished paper of every quality index equally.
