纸是如何生产出来的?中英文阅读
首先,纸是由一种叫作纤维的物质制成的。纤维可以来自很多地方,比如树木、废纸、棉花等等。
制造纸张的第一步是将纤维混合在一起。这个过程叫作浆料制备。制造浆料的方法有很多种,但其中最常见的一种是将纤维和水放在一个大桶里,然后用机器搅拌。
接下来,我们需要将浆料放在一张大网上。这个网叫作造纸机,它可以帮助我们将浆料制成纸张。
当浆料在造纸机上流动时,水会被过滤掉,留下纤维。最后,纤维会被压缩成一张张纸张。
最后,纸张需要经过一些处理才能变得更加平整、光滑和白色。这个过程叫作涂布。
经过这些步骤,纸就制作完成啦!它可以被用来写字、画画、包装礼物等等。你知道我们平常用的纸都是这样制造出来的哦。
First of all, paper is made from a material called fiber. Fiber can come from many places, such as trees, waste paper, cotton, etc.
The first step in making paper is to mix the fibers together. This process is called pulp preparation. There are many methods to make pulp, but the most common one is to put the fibers and water in a large tank and stir them with a machine.
Next, we need to put the pulp on a large mesh. This mesh is called a paper machine, and it can help us turn the pulp into paper.
As the pulp flows on the paper machine, the water is filtered out, leaving the fibers. Finally, the fibers are compressed into sheets of paper.
Finally, the paper needs to go through some treatments to become smoother, whiter, and more even. This process is called coating.
After these steps, the paper is made! It can be used for writing, drawing, wrapping gifts, and more. Now you know how the paper we use every day is made!
