Description

A kind of manufacture method of glassine paper
Technical field
The present invention relates to a kind of manufacture method of glassine paper, belong to pulp technology for making paper.
Background technology
Glassine paper is a kind of industrial paper, and Ge Laxin is made by rewetting, supercalendering and after applying the processes such as silicone oil Paper.Lattice Racine paper（GLASSINE）Quality is fine and close, uniform, there is good internal intensity and transparency.Be make bar coded sticker, The common used material of adhesive sticker, adhesive tape or toughness industrial goods.Lattice Racine paper has certain high temperature resistant, moistureproof, the function such as grease proofing, It is generally used for the packaging of the industries such as food, medicine.It is mainly used in：High-Speed Automatic labeling（Particularly suitable high speed label is pasted）It is special Adhesive tape, two-sided tape base material trade mark, laser anti-counterfeit mark and other release applications etc..It is mainly used in medical product as glue The release liners of band and casting product.Conventional grammes per square metre is 58g-120g.The purposes of lattice Racine paper and high-grade two-sided film release liners Similar, because the product is more environmentally-friendly, the market share from now on will be increasing.It is domestic with the people live in plenty in Zhejiang special paper, Zhejiang five The enterprise production Ge Laxin such as continent paper industry, the southern paper industry of Yiwu justice, Wuhan Chenming's paper industry（It is former）Based on paper, with the change of market capacity Greatly, increasing enterprise will participate in developing and producing Ge Laxin（It is former）Paper.My company is not because have supercalender, therefore only Develop glassine paper.
Glassine paper is processed as Ge Laxin paper processes：Body paper-rewetting -- supercalendering --- applying silicone oil --- rewind slitting
Lattice Racine paper primary quality measure includes：Smoothness, transparency, water imbibition, tensile strength, homogeneity etc..
The glassine paper of my company's exploitation in 2016, main innovation point have：(i) from slurry selection, beating process and papermaking Technical study and innovation, the requirement of client, main research are fully met in the product quality of the glassine paper of PM9 exploitations Including：1. study grout structure；Select commodity sulfate bleached wood pulp（Needle and broad-leaved）For primary raw material.2. research is optimal Wet end furnish；By laboratory handsheet and the research with slurry of paper machine, it is determined that optimal wet end furnish scope ----softwood pulp: leaf wood Slurry=（70-80）∶（30-20）.3. optimal beating degree control range is studied, in order to allow paper machine to be dehydrated and manufacture paper with pulp normally, together When meet to improve needle slurry ratio, it is ensured that end product Ge Laxin paper transparencies are high；We start with research from beating process, pass through Using fast beating mode test of many times research, in general Ge Laxin paper beating process is overturned, has finally been determined optimal Beating degree control range（Such as broad-leaved slurry beating degree control 22-260SR, needle slurry beating degree control 22-300SR）.4. use Film transfer surface sizing equipment carries out top sizing processing, and glassine paper does not use oxidized starch glue-applying technique, but adopts With full PVA glue-applying technique, boil technique and insulation is operated after all being groped by many experiments and just determined, it is ensured that the PVA of ton paper Resin added reaches 15-20kg.(ii) product structure transition innovation, lifting company profitability（The call of response company, product knot Structure is made the transition from Cultural Paper to industrial paper, and glassine paper rate of gross profit is apparently higher than company's existing product）；Simultaneously occupation rate of market by Year increase, it is an industrial paper new product for being worth exploitation.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of glassine paper.
The technical scheme is that：A kind of manufacture method of glassine paper, including the use of softwood pulp, leaf wood Slurry, through being beaten respectively, with slurry and auxiliary material is added, l Water Paper page is manufactured paper with pulp, preceding drying, coating applying glue, after the processing step such as dry, it is special Sign is：

(2) freedom after slurry pulping：Softwood pulp 22-30oSR；Hardwood pulp 22-26oSR；
(3) auxiliary material is to oven dry stock dosage：(a) AKD weight compares 1.5-2.0%；(b) retention agent weight compares 0.02- 0.04%；(c) cationic starch weight compares 0.8-1.0%；
（4）Applying glue portion：With PVA, concentration 9%, upper gum concentration 4.0% are boiled, it is ensured that PVA coating weights are in 15-20kg/ ton paper. Gauge stick model：1#, gauge stick pressure 100kpa；Up/down roller applying glue flow is respectively 1050L/min/1050L/min；Two sides Top sizing, one side are controlled in 0.5-0.8g/m2, page tension force 220N/m before applying glue portion2, page tension force behind applying glue portion 200N/m2；
(5) paper machine other specification：Network speed 680m/min, top net dehydrating amount 27%, head box opening degree of slice lip 9.7mm, one Line ball pressure：900 kN/m, two line ball pressure：900 kN/m；Curl tension：400kN/m；
(6) rolling condition：Calender separates, and is not pressurized；
(7) glassine paper is quantitative：62-78g/m2, moisture（4.0-7.0%）, form and aspect raw white, longitudinal fracture length （≥7.0Km）, water imbibition（20-28g/m2）, tightness（≤0.74g/m2）, air permeability（≤120ml/min）, transversal stretching rate (≤ 3.0%), thickness is stable, formation of sheet is good, planarization is good.
