1，硅胶干燥剂

1. Silica gel desiccant

其原料是一种无色，无味，，化学性能稳定，吸湿性好的高微孔含水二氧化硅。它广泛用于仪器，皮革，箱包，食品，纺织品，设备等。其功能是在储存和运输过程中控制环境的相对湿度，以防止物品受潮，发霉和腐蚀。

The raw material is a kind of colorless, tasteless, non-toxic, stable chemical properties and good moisture absorption of high microporous aqueous silica. It is widely used in instruments, leather, bags, food, textiles, equipment and so on. Its function is to control the relative humidity of the environment during storage and transportation, so as to prevent the articles from being damp, moldy and corroded.

2，纤维干燥剂

2. Fiber desiccant

它由植物纤维制成，并经过特殊工艺精制而成。值得一提的是，涂覆的纤维干燥剂片节省空间并且方便实用。它的吸湿能力与其自身重量相当，远高于其他干燥剂。由于其适中，和卫生，因此它是许多保健产品，药品和生物干燥剂的较好选择。

It is made of pure natural plant fiber and refined by special technology. It is worth mentioning that the coated fiber desiccant sheet saves space and is convenient and practical. Its moisture absorption capacity is equivalent to its own weight and much higher than other desiccants. Because of its moderate price, safety and hygiene, it is a better choice for many health products, drugs and biological desiccants.

3，蒙脱石干燥剂

3. Montmorillonite desiccant

干燥剂被广泛用于医疗保健，食品包装，光学仪器，电子产品，军用产品，民用产品和其他不能被油或天气密封的产品。由于使用原料膨润土，具有吸附能力强，吸附速度快，无味，无环境污染，无接触腐蚀，绿色环保，无味，无害的特点。对人体具有良好的吸附性能，吸附活性，静态和除臭功能。

Desiccant is widely used in medical care, food packaging, optical instruments, electronic products, military products, civil products and other products that cannot be sealed by oil or weather. Due to the use of pure natural raw material bentonite, it has the characteristics of strong adsorption capacity, fast adsorption speed, tasteless and non-toxic, no environmental pollution, no contact corrosion, green environmental protection, tasteless, non-toxic and harmless. It has good adsorption performance, adsorption activity, static dehumidification and deodorization function to human body.

4，生石灰干燥剂

4. Quicklime desiccant

高中化学课上曾讨论过生石灰，其主要成分是氧化钙，通过化学反应达到吸水，具有不可逆性。常见的是在“雪糕”中使用这种干燥剂。另外，它也常用于电器，皮革，服装，制鞋，茶叶等。但是，由于生石灰属于强碱，因此具有很强的腐蚀性，有时老年人和儿童的眼睛受伤，因此逐渐被淘汰。

High school chemistry class once discussed quicklime. Its main component is calcium oxide. It absorbs water through chemical reaction and is irreversible. It is common to use this desiccant in "ice cream". In addition, it is also commonly used in electrical appliances, leather, clothing, shoemaking, tea, etc. However, because quicklime is a strong alkali, it is highly corrosive. Sometimes the eyes of the elderly and children are injured, so it is gradually eliminated.

5，氯化钙干燥剂

5. Calcium chloride desiccant

氯化钙主要以碳酸钙和盐酸为原料，并通过反应合成，过滤，蒸发浓缩，干燥等工艺进行精制。在食品工业中用作钙强化剂，螯合剂，固化剂，干燥剂等。同时，还可以用作气体的干燥剂，生产醚，醇，丙烯树脂等的脱水剂。氯化钙为多孔性块状，颗粒状或蜂窝状原料，无味，味微苦，溶于水，无色。

Calcium chloride is mainly refined from calcium carbonate and hydrochloric acid through reaction synthesis, filtration, evaporation concentration and drying. It is used as calcium fortifier, chelating agent, curing agent, desiccant, etc. in food industry. At the same time, it can also be used as a desiccant for gas and a dehydrating agent for the production of ether, alcohol, propylene resin, etc. Calcium chloride is a porous block, granular or honeycomb raw material, tasteless, slightly bitter, soluble in water and colorless.
