Used with the place such as outgoing.With the continuous improvement of people's living standard, paper for daily use is rapidly become in people's life most
For one of close consumer goods, the production of the paper for daily use in China and the market demand also increase rapidly, and people are to paper for daily use
Quality requirement also more and more higher, had not only required the intensity of paper but also had required the light softness of paper.The quality of paper for daily use quality will
The service condition of consumers in general is directly affected, increasing enterprise starts to pay attention to the research and development to new product to meet market need
Ask.It is seldom as the paper mill of raw material using wood pulp merely in China, it is raw material mostly using waste paper, waste paper kind is different, contained by it
Some debris are also different.A large amount of uses of non-wood-fiber in paper industry, the ratio increase that particularly waste paper uses so that
The class foreign matter that sticks together in paper machine increases, and has influence on effective work of paper machine, viscous cylinder, the phenomenon of viscous dry net occurs, and paper is producing

Plinth is oily to be easier to degrade compared with highly viscous poly alpha olefin base oil, but generally speaking poly alpha olefin base oil due to its water
Dissolubility is not mostly fine, therefore it is later to be not easy the microbial degradation by environment that it, which is entered in environment, will not be to life yet
Thing is toxic and stimulation, is still green base oil.Synthesizing ester oil is the esterification reaction product of organic acid and alcohol, synthetic fat
There is good ability in terms of boundary lubrication, due to closely similar with the structure of natural oil, all with aliphatic radical structure, therefore its
It is a kind of Green Lubricants with good biological degradability, but synthetic ester is raw materials used to be also from greatly mineral oil,
And its price is higher relative to mineral oil based lubricating oil, polyether oil etc..PPG and referred to as polyethers (PAG),
It is using the compound containing active hydrogen group as initiator, is carried out by monomer of oxirane, expoxy propane or its mixture
Polymer made from ring-opening polymerization.Expressive force of the polyether oil in terms of oxidation stability is not fine, the phase of polyether product
For capacitive nor very good, it is poor with the being mutually dissolved property of mineral oil and artificial oil, and the traditional commercial synthesis of polyether oil uses
Be oxirane, expoxy propane homopolymerization or copolymerization, these materials of tracing to its source still come from mineral oil.Vegetable oil plant oil
It is natural organic-compound easily biological-degradable, itself has very excellent lubricity again, is preferable base oil, but plants
Thing oil is a kind of Unsaturatcd fatty acid glycerides, containing substantial amounts of carbon-carbon double bond, causes its oxidation stability poor, it may occur that
Very serious oxidative phenomena, and more easy to foaming than mineral oil, these defect factors limit oily based on vegetable oil
