Description

A kind of Yankee dryer remover
Technical field
The present invention relates to a kind of remover, and in particular to a kind of yankee dryer surface remover.
Technical background
In household paper manufacturing process, because the speed of service of paper machine is more and more faster, paper web must be smooth at high speeds Depart from drying cylinder;And because the fiber of paper pulp is shorter, impurity is more, these impurity may be bonded with dryer surface, be unfavorable for paper Width smoothly departs from from drying cylinder, so the use of drying cylinder remover just seems necessary, directly affect paper production continuity, High speed.
The content of the invention
It is an object of the invention to provide the remover and preparation method of a kind of yankee dryer surface, this remover is not It is only capable of solving the problems, such as that paper web glues cylinder, makes its de- cylinder;It is further to can be used for high-speed paper machine, promote the serialization of paper technology, The problems such as reducing trachoma, the blackspot of paper surface, the smoothness of raising paper surface that can be by a relatively large margin;Can protect simultaneously Drying cylinder, extends drying cylinder service life, so as to improve paper production efficiency and quality.
What the present invention was achieved through the following technical solutions:
A kind of Yankee dryer remover, is made up of following components by weight percentage:
20 ~ 90 parts of oil
5 ~ 50 parts of emulsifying agent
1 ~ 30 part of co-emulsifiers
Described oil is one or more in vegetable oil, mineral oil;
Described emulsifying agent is sorbester p18(Sorbitan monostearate), sorbester p17(Sorbitan monooleate), Tween 80(It is poly- Oxygen ethene Arlacel-80), triton x-100(Octyl phenyl polyoxyethylene ether)、Brij30(Polyoxyethylene laural Ether)、Brij35(Brij-35), in one or more;
Described co-emulsifiers are one or more in soybean oleic acid, Brij.
Optimization, the oil is mineral oil.
Further, the mineral oil be 3# mineral oil, 5# mineral oil, 7# mineral oil, 10# mineral oil, 15# mineral oil, One or more in 26# mineral oil, 32# mineral oil, 46# mineral oil;Selected as one kind, mentioned emulsifier is mass ratio 1: 3 sorbester p18 and Tween 80.
Selected as one kind, mentioned emulsifier is mass ratio 1:7 sorbester p18 and triton x-100.
Selected as one kind, mentioned emulsifier is mass ratio 1:2 sorbester p18 and Brij35.
Selected as one kind, mentioned emulsifier is mass ratio 5:9 sorbester p17, Brij35.
A kind of preparation method of above-mentioned Yankee dryer remover is:20 ~ 90 parts are added in dry reactor Mineral oil;Then to 5 ~ 50 parts of emulsifying agents are added in reactor, mix 5 ~ 20 minutes;Again in above-mentioned solution add 1 ~ 30 parts of co-emulsifiers, stir 5 ~ 20 minutes.
The beneficial effects of the invention are as follows:
Application of the remover on Yankee dryer, is mainly first mixed, by pipe with remover, viscous cylinder agent with water in the sink Road, then be sprayed on drying cylinder by shower nozzle and use.Wet web is heated by drying cylinder, in the presence of oil in remover, is stripped Get off, depart from drying cylinder.A kind of remover of the present invention, is mainly made up of oil, emulsifying agent, the part of co-emulsifiers three.
Wherein, emulsifying agent is generally surfactant, and molecule is typically by the alkyl chain and hydrophilic group of oleophylic, such as hydroxyl group Into.In the present invention, the emulsifying agent for being used, oleophilic moiety and mineral oil are a side, and hydrophilic segment is a side with hydrone.This Planting interaction makes interfacial tension there occurs change, and the change of interfacial tension makes liquid be scattered in another liquid in one form In, that is, form emulsion.In addition, interfacial film has certain intensity, shielded with dispersed phase drop, make drop mutual Coalescence is difficult in collision.In the industrial production, emulsifying agent prepares general more than using single surfactant, but uses Two or more surfactant is compounded, the performance of the compound for obtaining than original one-component performance more It is excellent.
While using emulsifying agent, while to adding co-emulsifiers in emulsion system.The emulsifying agent that the present invention is used Auxiliary agent is soybean oleic acid or Brij, with excellent dispersibility, while the stabilization of emulsion system can be kept Phase.The auxiliary agents such as soybean oleic acid can form interface obstacles in emulsion droplet surface, delay monomer to be moved to big drop from droplet Move.Oil water interfacial tension is strongly reduced during the addition of the auxiliary agents such as soybean oleic acid makes drop, adds the monomer droplet ratio after auxiliary agent not Small many of the monomer droplet size of adding assistant, electric conductivity value reduces, and stability increases.
The addition of emulsification system, can be such that the water in oil in remover and paper technology and viscous cylinder agent is sufficiently blended in Together, so as to promote the carrying out of technique on drying cylinder.Reduce paper surface trachoma, blackspot the problems such as, can be by a relatively large margin carry The smoothness of paper surface high;Drying cylinder can be protected simultaneously, extend drying cylinder service life.So as to improve paper production efficiency and product Matter.
