高得率制浆机械与设备的相关知识
of high-yield pulping machinery and equipment

高得率制浆方法
The high-yield pulping methods

保留了大部分或者全部的木素
retain most or all of lignin

使得所生产的高得率浆
which enable that the high-yield pulp

不仅具有较高的得率
has not only higher yield

更具有较好的光散射系数
but also better light scattering coefficient

且所生产的纸张
and the produced paper

具有较好的松厚度和挺度
has better loose thickness and stiffness

高得率制浆设备现今主要包括
Nowadays, the high-yield pulping equipments mainly includes

磨石磨木机、磨浆机和搓丝机
the stone ground wood machine, refiner and knead rolling machine

在1940年，德国科勒尔首先
In 1940, Germany Keller first

发明了磨石磨木机
invented the stone ground wood machine

在1960以前，全部高得率纸浆
Before 1960, all the high-yield pulp

都是用磨木机生产的
was produced by the ground wood machine

磨浆机出现后
and after the appearance of the refiner

得到了迅速的发展
it was developed rapidly

到1990年，仅用了三十年的时间
By 1990, it only took 30 years

50%以上的高得率纸浆
and more than 50% of the high-yield pulp

就由磨浆机生产出来
was produced by the refiners

由磨木机快速转向磨浆机
The rapid transition from the ground wood machine to the refiner

主要由于它有三个明显的优点
was mainly based on its three obvious advantages

①它是可以利用锯材厂的废料(木片和锯屑)
① It can use the waste (wood chips and sawdust)

以替代木段
to replace the short-cut wood

②较高的纸浆性能，强度的突破
② Higher pulp properties and breakthrough in strength

③第三就是设备综合效率高
③ The third is the high comprehensive efficiency of equipment

这是磨浆领域的一个重大的突破
It is a major breakthrough in the field of refining

推动了高得率制浆的发展
and promotes the development of high-yield pulping

以搓丝机为关键设备形成的制浆工艺
The pulping process formed by the key equipment of the thread rolling machine

称为挤压机械制浆
is called the EMP (Extruder Mechanical Pulping)

挤压机械制浆方法
The extruder mechanical pulping method

是根据木材轴向受压时
is generated base on the theory that the buckling effect of the wood

产生的皱曲作用能使纤维分离
under axial compression can separate the fibers

也就是利用木材轴向受压磨浆时
that is, when refining by adoption of wood axial compression

电能消耗低
the energy consumption is low

同时生产出的纤维长
and the pulp with long fiber and

而且结合力好的浆的理论而产生的
good binding force is generated at the same time

这对于高得率制浆的节能
This is of great significance for the energy saving of high-yield pulping

和纸浆质量的提升具有重要的意义
and improvement of pulp quality

降低了高得率制浆的生产成本
which reduces the production cost of high-yield pulping

也扩大了纸浆的应用范围
as well as expands the application of pulp

这也推动了高得率纸浆
It also promotes the development of high-yield pulp

在APMP、BCTMP等化机浆的发展
in APMP, BCTMP and other chemimechanical pulp

由于搓丝机本身不能一次
Because the knead rolling machine itself cannot

生产出合乎质量要求的纸浆
produce the pulp meeting the quality requirements at one time

尚需接着用常压磨浆机进行精磨
it is necessary to use the atmospheric refiner for fine grinding

使其达到质量要求
to make it meet the quality requirements

现在就让我们一起学习有关
Now, let's learn about
