卡纸：从生产到回收，你知道多少？ 一、生产阶段 卡纸是一种常用的纸张类型，其生产过程主要涉及到原材料的准备、混合、制作、成型和加工等步骤。首先，从天然植物纤维（如木材）或人造纤维中提取纤维素，这是卡纸的主要原料。然后，将纤维素与各种添加剂混合，如增白剂、填充剂和粘合剂等，以改善纸张的物理和化学性能。接着，通过制浆、漂白和净化等工序，将混合物制成纸浆。最后，将纸浆通过一系列的机械加工过程，如网部成型、压榨、干燥和卷曲等，最终形成卡纸的形状。

二、使用阶段

卡纸在生活中的使用非常广泛，包括打印文件、制作名片、包装盒等。在使用过程中，我们需要注意保护和节约资源。尽量减少不必要的浪费，避免过度使用和滥用卡纸。同时，我们也要注意对卡纸的保养和保护，避免长时间暴露在潮湿或高温的环境中，以免影响其使用寿命和质量。 三、回收阶段 卡纸的回收是一项重要的环保行动。回收卡纸可以减少对自然资源的开采和消耗，同时减少垃圾填埋和焚烧产生的污染。回收过程中，首先需要对卡纸进行分类和清洗，去除其中的杂质和污染物。然后，将清洗后的卡纸进行破碎、磨浆等处理，使其恢复成类似于原始纸浆的状态。最后，通过一系列的加工过程，将回收的卡纸再次制成纸张或纸制品，实现资源的再利用。 四、翻译成英文

Cardstock: From Production to Recycling, How Much Do You Know?

Production stage: Cardstock is a commonly used type of paper, and its production process mainly involves the preparation, mixing, production, shaping, and processing of raw materials. Firstly, cellulose is extracted from natural plant fibers such as wood or artificial fibers as the main raw material for cardstock. Then, it is mixed with various additives such as brighteners, fillers, and binders to improve the physical and chemical properties of the paper. Subsequently, through processes such as pulping, bleaching, and purification, the mixture is made into pulp. Finally, through a series of mechanical processing processes such as wire section shaping, pressing, drying, and curling, the pulp is finally formed into the shape of cardstock.

Use stage: Cardstock is widely used in daily life, including printing documents, making name cards, packaging boxes, etc. During use, we need to pay attention to protecting and conserving resources. We should try to reduce unnecessary waste and avoid excessive use and abuse of cardstock. At the same time, we also need to pay attention to the maintenance and protection of cardstock to avoid long-term exposure to damp or high-temperature environments that may affect its service life and quality. Recycling stage: Recycling cardstock is an important environmental action. Recycling cardstock can reduce the exploitation and consumption of natural resources while reducing pollution from landfilling and incineration. In the recycling process, cardstock needs to be sorted and cleaned first to remove impurities and pollutants. Then, the cleaned cardstock is crushed, ground into pulp, and processed to restore it to a state similar to the original pulp. Finally, through a series of processing processes, the recycled cardstock is turned into paper or paper products again to achieve resource reuse.
