Description
Technical field
The present invention relates to fruit paper bag technical field more particularly to a kind of production methods of the hydrophobic fruit paper bag of single side.
Background technique
At present in fruit before sales, especially citrus before sales, the fruit cultivating bag paper that fruit uses passes through solarization some months rain
Leaching, fruit cultivating bag paper surface is very dirty, directly affects the appearance of fruit, influences the sale of fruit, therefore need to remove fruit paper bag,
And fruit is sorted, the fruit after sorting is repacked upper fruit paper bag and sold again, the fruit appearance after repacking
More preferably, the class of moisture is greatly improved, since the Some Fruits surface after sorting with water or need to be stored in frozen storehouse,
Therefore it needs fruit paper bag to have certain hydrophobic effect and wet potent fruit, prevents fruit paper bag from rupturing.
The fruit bay paper of repacking, not requiring nothing more than paper strength will get well, it is also necessary to and surface hydrophobicity has certain wet strength,
Preferable printing performance is needed to have simultaneously, since the hydrophobing agent of fruit bay paper generally uses paraffin wax emulsions, causes fruit bay paper
It is not bright-coloured that the color after printing or printing is not easy in printing.
The hydrophobic fruit paper bag of single side of the invention can effective solution problem above, being coated with the hydrophobic one side of hydrophobing agent can expire
The demand of sufficient paper water resistant, the requirement of printing can be met by being not coated with the not hydrophobic one side of hydrophobing agent.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and the hydrophobic fruit paper bag of a kind of single side proposed
Production method.
To achieve the goals above, present invention employs following technical solutions:
A kind of production method of the hydrophobic fruit paper bag of single side, the process include the following steps:
A, wood-pulp board size degradation, using hydrabrusher by bleaching needle-point leaf pulp plate size degradation at fiber suspension；
B, it is beaten, mashing operation is carried out to above-mentioned fibrous raw material by mill, and then slurry is made to meet paper machine production requirement；
C, paper pulp obtained in step b is sent into papermaking approach system by streaming forming, by desander, the pressurized screen in system,
Fiber impurity is removed, and makes into paper by the way that wet strength agent, sizing agent AKD, retention agent is added in paper machine streaming section and meets water resistant, wet
Finally l Water Paper page is made in the web part of paper machine of paper machine in intensity requirement；
D, it squeezes, press operation is carried out to l Water Paper page made from step e, obtains the l Water Paper page of smooth, certain mass dryness fraction；
E, obtained page after step f squeezing is dried in front baking, use the paper of front baking section at paper mass dryness fraction 90%
Left and right, to adapt to the requirement of sizing applicator top sizing；
F, sizing applicator carries out monoplanar surface sizing to the paper after step g, and assign system has single side hydrophobic effect at paper；
G, rear to dry, the page obtained after step h squeezing is dried, out after dry section at paper mass dryness fraction 92% or so, with
Meet product quality requirement；
H, it batches, the paper roll that section is dried after going out takes in rolls.
Preferably, the optional import bleaching needle-point leaf pulp of bleaching needle-point leaf pulp in the step a.
Preferably, the mill of the optional G model of mill in the step b.
Preferably, the step c sequentially adds wet strength agent, sizing applicator AKD, retention agent during page is made.
Preferably, in the step g, using sizing applicator, hydrophobing agent is coated using gauge stick on one side, another side utilizes metering
Stick applies supernatant water, prevents two-sided hydrophobic effect.
Compared with prior art, resist the beneficial effects of the present invention are: being coated with the hydrophobic paper that can satisfy on one side of hydrophobing agent
The demand of water, the requirement of printing can be met by being not coated with the not hydrophobic one side of hydrophobing agent.Production technology is easy, and supplementary product onsumption is few, production
It is at low cost, remarkable in economical benefits.
