3) respectively three kinds of slurries are reasonably pulled an oar, control beating degree, slurry is detected, work out rational slurry pulping degree, avoid being undertaken fiber shearing for a long time and damage, three kinds of slurries are carried out net part forming according to certain ratio uniform mixing by surface layer approach system, study rational jet-wire ratio and control fiber in wet end dehydration, study the frequency of shake to the slurry impact at net part forming simultaneously, the mass dryness fraction of wet web is measured, to determine that rational jet-wire ratio and shake frequency are on the slurry impact at net part forming at couch roll place;
4) control press section one press, the line pressure of two pressures, the cases of dehydration of detection paper web, by two road boots pressure squeezings, one is pressed in and prevents from improving under paper web conquassation line pressure and try one's best dehydration, suitably reduces paper web two press-dehydrating, it is achieved paper web is in the uniform dehydration of press section banner;
5) control the rational drying curve of drying section, make into paper surface strength in dry run, keep good intensity;
6) by big roller footpath sizing equipment, adjustment solid content ensures into paper surface with glue application solution concentration, formula and has higher intensity and toughness, control resin added, keep into paper ash and divide in technology requires, control into paper moisture, one-tenth paper is carried out peplos, it is prevented that become paper to cause that moisture changes greatly because of the change in season。
The production technology of described kraft liner cardboard paper, it is characterised in that jet-wire ratio is 1.0-1.05。
The production technology of described kraft liner cardboard paper, it is characterised in that: the one-tenth paper ash sub-control system of described kraft liner cardboard paper is within 8.0%。
The production technology of described kraft liner cardboard paper, it is characterised in that: the one-tenth paper moisture Control of described kraft liner cardboard paper is 8.0 ± 2.0%。
Beneficial effect: the production technology of kraft liner cardboard paper provided by the invention, pulping process improves the intensity of fiber, select suitable feedstock, improve proportioning raw materials, adopt classification technique to improve the fibre length of surface layer slurry, reduce the consumption of chopped fiber, while keeping fibre strength, improve beating degree, reduce the shearing to fibre length and damage;Paper-making process is studied new jet-wire ratio, slurry is made to arrange dehydration on forming net more reasonable, fiber combines better, interweave evenly, adopt wet end shake technology, make fiber banner dehydration evenly on forming net, prevent fleeces from gathering, improve into the surface quality of paper, by press section boots pressure squeezing and and rational drying curve, the surface strength making into paper is maintained, become paper web moisture profile uniform, paper surface is become to adopt big roller footpath application techniques to improve degree of sizing, it is enhanced to paper surface strength and controls surface resin added, it is precisely controlled to paper ash divide and moisture。Improve product quality, reduce production cost, make product take advantage in the same industry is competed, there is good market prospect。Having the advantage that (1) becomes paper pop strength and folding strength to reach technical standard, improve product competitiveness in the market, becoming paper ash sub-control system within 8.0%, moisture Control is 8.0 ± 2.0%;(2) slurry is evenly distributed, and jet-wire ratio reaches 1.0-1.05;(3) improving slurry and go out wet end mass dryness fraction, drying section steam consumes reduction by 2%, year steam saving 12000 tons, reach the purpose that test is energy-conservation。
