纸的制作过程
过程 制浆为造纸的第一步,一般将木材转变成纸浆的方法有机械制浆法、化学制浆法和半化学制浆法等三种。过程 纸料的调制为造纸的另一重点,纸张完成后的强度、色调、印刷性的优劣、纸张保存期限的长短直接与它有关。一般常见的调制过程大致可分为以下三步骤: 1、 散浆 2、打浆3、加胶与充填
Process pulping is the first step in papermaking, and three methods, such as mechanical pulping, chemical pulping and semi chemical pulping, are used to convert wood into pulp. The modulation of process paper is another important point of paper making. The strength, hue, printing quality and the duration of paper storage directly relate to it. Generally, the common modulation process can be divided into three steps: 1, 2, 3, glue and filling
过程 抄纸部门的主要工作为将稀的纸料,使其均匀的交织和脱水,再经干燥、压光、卷纸、裁切、选别、包装,故一般常见之流程如下:
The main work of process papermaking department is to uniformly interweave and dehydrate the thinner paper, and then dry, calendering, reel, cut, pick and package.
1、纸料的筛选 将调制过的纸料再稀释成较低的浓度,并借着筛选设备,再次的筛除杂物及未解离纤维束,以保持品质及保护设备。
1, the screening of paper materials will dilute the modulated paper to a lower concentration, and then screen out the impurity and unbroken fiber bundle by screening equipment, so as to maintain the quality and protect the equipment.
2、网部 使纸料从头箱流出在循环的铜丝网或塑料网上并均匀的分布和交织。 3、压榨部 将网面移开的湿纸引到一附有毛布的二个滚辘间,藉滚辘的压挤和毛布的吸水作用,将湿纸作进一步的脱水,并使纸质较紧密,以改善纸面,增加强度。
2, the net department makes the paper material from the head box out in the circulating copper wire net or the plastic net and distributes and interweaves evenly. 3, press the wet paper web will be removed to two rolling with a cloth, through the suction effect of rolling and compression of cloth, wet paper will further dehydration, and make the paper more closely, to improve the paper strength.
4、烘缸 由于经过压榨后的湿纸,其含水量仍高达52 - 70%,此时已无法再利用机械力来压除水分,故改让湿纸经过许多个内通热蒸气的圆筒表面使纸干燥。
4, the moisture content of the dryer cylinder is still up to 52 to 70% due to the pressing wet paper. At this time, it is no longer able to use mechanical force to depress the moisture content, so it changes the wet paper to dry the cylinder surface through many hot steam cylinders.
5、卷纸 由卷纸机将纸幅卷成纸
5. Roll paper is rolled into paper by a paper machine.
6、裁切、选别 包装:取前面已卷成筒状的纸卷多支,用裁纸机裁成一张张的纸,再经人工或机械的选别,剔除有破损或污点的纸张,最后将每五百张包成一包(通常叫做一令)
6, cutting and sorting packaging: the front has been rolled into a cylindrical roll into a plurality of paper cutter cutting, then don't choose artificial or mechanical damage or remove stains, paper, finally, each of the five hundred packaged (usually called an order)
