Abstract
The invention relates to a glue applicator of papermaking equipment and an AKD surface direct glue application method utilizing the device. The device comprises a glue application machine located in a production line of the papermaking equipment, and an inlet pipe of a glue application agent inlet of the glue application machine is connected with an AKD liquid storage groove and a surface glue application liquid storage groove through a metering pump and a liquid storage pump respectively; a glue application agent reflux opening of the glue application machine is directly connected to the inlet pipe through a reflux pipe. By means of the device and method, in the papermaking and glue application process, AKD obtained after glue is applied to the surface directly does not flow back to a glue liquid groove directly, instead, the AKD flows back to the inlet pipe of the glue application machine directly, and time for staying in high temperature flue liquid of the AKD is reduced, so that the chance that the AKD generates hydrolysis and forms sticky substance ketone is reduced, the phenomenon that paper breaking caused by a paper machine is reduced, product quality and stability in the production process are improved, and pollution is reduced.
Description
Technical field
The present invention relates to the size applicator of a kind of paper making equipment and use the direct glue applying method in AKD surface of this device.
Background technology
AKD(alkyl ketene dimer) it is one of kind the most frequently used in the neutral-to-alkaline sizing agents in paper technology, it can give the water resistant ability that paper is superior, it is possible to gives the ability of the anti-edge penetration of cardboard, meanwhile, is substantially improved the physical property of paper.
The resin application methods that the size applicator of tradition paper making equipment adopts has direct two kinds of common methods such as applying glue and the direct applying glue in surface in slurry:
A kind of method is directly applying glue in AKD slurry, and its glue-applying technique is: adopt dosing pump approach system before paper machine net to add neutral sizing agent AKD, keeps through online, dehydration, the operation such as dry complete applying glue task.In AKD slurry directly applying glue exist main drawback is that 1, sizing agent consumption high, number of dropouts is big, and applying glue influence factor is many；2, web part of paper machine to keep high first-past retention；3, part sizing agent runs off and enters plain boiled water blood circulation, increases systemic contamination degree, easily causes the disconnected paper of paper machine and produces hole problem, and adds many besides row's plain boiled water pollutions to environment；4, easily produce roll banding, viscous cylinder, adhesive hair cloth etc. produce obstacle.
Another kind of method is the direct applying glue in AKD surface, and its glue-applying technique is: adopting dosing pump to be mixed with starch surface sizing liquid (Oxytarch) by neutral sizing agent AKD, utilize paper machine surface size press to carry out applying glue, unnecessary glue is back in glue groove.The method can efficiently solve the disadvantages mentioned above that neutral sizing agent AKD tradition plasm-glue-blending technique exists.What the direct glue-applying technique stream in existing AKD surface existed main drawback is that 1, backflow glue is passed straight back in glue groove, causes part AKD to be back in glue groove；2, the at a higher temperature and often time of the AKD in backflow glue through recycling, cause residual AKD to hydrolyze to form glutinous shape thing ketone；3, sizing agent consumption is high.4, easily cause paper web after paper machine applying glue and produce viscous cylinder phenomenon, cause that paper machine breaks paper.
Summary of the invention
The technical problem to be solved is to provide and a kind of can reduce the AKD time of staying in high temperature glue, improves paper technology reliability, reduces the direct glue applying method of size applicator and AKD surface of the paper making equipment polluted.
The size applicator of the paper making equipment of the present invention includes the sizing applicator being arranged in paper making equipment production line, and the entrance pipe that the sizing agent entrance of described sizing applicator connects connects AKD liquid storage tank and surface size storage tank respectively through dosing pump and glue solution pump；The sizing agent refluxing opening of described sizing applicator is connected directly to described entrance pipe through reflux pipe.
The direct glue applying method in AKD surface of the present invention is: enters sizing applicator after making AKD liquid and surface size mix in the entrance pipe of sizing applicator and implements top sizing, unnecessary mixed liquor is made to be passed straight back to the sizing agent entrance pipe of sizing applicator, circular flow through the sizing agent refluxing opening of sizing applicator.
Described surface size is starch surface sizing liquid.
Assembly of the invention and method make in paper-making sizing process, AKD after the direct applying glue in AKD surface is not passed straight back in glue groove, but it is passed straight back to the entrance pipe of sizing applicator, effectively reduce the AKD time of staying in high temperature glue, thus reducing AKD to hydrolyze to form the chance of glutinous shape thing ketone, and then reduce paper machine and cause that paper machine breaks paper phenomenon, improves the stability of product quality and production process, what reduce AKD makes consumption, decreases pollution.
