Abstract
The present invention provides a kind of new dyeing ox bottom coated manila production method, this method mainly by yellow, black, red three kinds of dyestuffs, dyes certain 100% specific deinking prime cement online.The invention reside in will give up boxboard as prime cement using the poor state of operation ratio before, replace with the dyeing prime cement of 100% Deinking Pulp, so as to reduce the paper machine body paper broken hole as caused by front baking in operation, reduce disconnected paper number, increase substantially the operation ratio of paper machine, A grades of rates of finished paper are improved, further reduce ton paper cost.In the case of same physical intensity index, back appearance is finer and smoother, miscellaneous point is reduced, visual effect is more preferable, is more favored by client.
Description
Technical field
Technical field more particularly to a kind of new dyeing ox bottom coated manila producer the present invention relates to papermaking
Method, the shading process of yellow, black, red three kinds of direct dyess adjustment L, a, b value.
Background technology
Because all states of prime cement give up boxboard paper pulp, and adhesive content in slurry during the coated manila of production aurochs bottom
It is higher, cause base web broken hole more in preceding drying, therefore make a big impact to the operation ratio of paper machine, the paper number that breaks is more, into
A grades of rates of paper are relatively low, and ton paper cost is higher.Therefore done on the coated manila production line of prime cement in state's boxboard that gives up, it is this kind of due to
Paper defects caused by sicker, break paper the problems such as, seriously hinder the development speed of such paper kind, but for blocking with ox on the segmenting market
The coated manila of background color then belongs to vacuum vacancy.Therefore research one kind can either meet good print adaptive, and be capable of providing
The paper kind of certain physical strength is imperative to meet the needs of terminal client.
Invention content
The object of the present invention is to provide a kind of new dyeing ox bottom coated manila production method, to solve the prior art
Above-mentioned deficiency.
The purpose of the present invention is be achieved through the following technical solutions：
A kind of new dyeing ox bottom coated manila production method, this method include the following steps：
(1) after paper pulp streaming online, flow is controlled to add in yellow, black, red three kinds of dyestuffs to base pastes by pumping frequency；
(2) yellow, black, red three kinds of dyestuff flows and bottom starching pump discharge and prime cement concentration interlock, i.e., yellow, black, red three kinds
The product that dyestuff flow is multiplied by prime cement concentration with bottom starching pump discharge is linear；After paper machine speed, which reaches, stablizes constant,
The product that bottom starching pump discharge is multiplied by prime cement concentration is just steady state value；
(3) bottom surface L, a, b value situation of change is monitored on-line using into paper scanning support；
(4) according to the situation of change of L, a, b value, yellow, black dyes carries out plus-minus adjustment with 0.05kg/t every time；Red dye
It is added and subtracted every time with 0.03kg/t during material adjustment；
(5) bottom surface L, a, b value is detected by the form and aspect instrument in laboratory into after paper last volume, is corrected into paper scanning support on-line monitoring
Bottom surface L, a, b value deviation.
The weld separately through a pipeline, black and orchil it is admixed together after added by a pipeline
Enter into 100% deinking bottom slurry.
The orchil is Niu Kahong, anion red direct dyes；
The weld is ox card Huang, cationic yellow direct dye；
The black dyes is anion red direct dyes.
Dyestuff is added to bottom paper machine by the orchil, weld, black dyes using 5 kilograms of pressure dilution waters
After stock tank starching pipe, before bottom raw material.(prime cement concentration is 3.0% ± 0.5%).
100% Deinking Pulp of bottom raw material is 8#It is made after imported from America deinking flotation.
100% U.S. useless 8#Deinking prime cement colouring method parameter and indexes.
| Into paper detected value | L | a | b |
| Allowable fluctuation range | 60.5-61.8 | 5.2-5.6 | 16.5-17.0 |
| Dyestuff | Black | It is red | Yellow |
| Ton slurry dosage | 2.75kg/t | 0.82kg/t | 4.7kg/t |
Beneficial effects of the present invention are：
(1) the more former boxboard of ox card background color coated manila dyed by prime cement does the coated manila at bottom and possesses higher
Operation stability, broken hole, disconnected paper are significantly less caused by sicker.
(2) through hyperchromatic ground ox back appearance it is finer and smoother compared with original place ox, it is miscellaneous point reduce, visual effect it is more preferable
(3) because the sicker of dyeing ground ox into paper is less, therefore client's printing equipment runs more stable, the use for client
It is more advantageous, more favored by client, thus to adapt to wider and Special use group demand.
Specific embodiment
In order to improve the paper machine operation efficiency of ox bottom coated manila, reduce broken hole and break paper, effectively reduce ton paper cost.This
Inventive embodiments provide a kind of new dyeing ox bottom coated manila production method.In the inventive solutions, pass through
Using 100% U.S. useless 8#Deinking Pulp dyeing production ox bottom coated manila, so as to reach raising paper machine operation stability, because of glue
Broken hole, disconnected paper are less caused by viscous object；Back appearance exquisiteness, miscellaneous point are reduced, visual effect is more preferable, with reference to specific implementation
Example illustrates technical scheme of the present invention.
