1，硅膠干燥劑

1. Silica gel desiccant

其原料是一種無色，無味，無毒，化學性能穩定，吸濕性好的高微孔含水二氧化硅。它廣泛用于儀器，皮革，箱包，食品，紡織品，設備等。其功能是在儲存和運輸過程中控制環境的相對濕度，以防止物品受潮，發霉和腐蝕。

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，纖維干燥劑

2. Fiber desiccant

它由純天然植物纖維制成，并經過特殊工藝精制而成。值得一提的是，涂覆的纖維干燥劑片節省空間并且方便實用。它的吸濕能力與其自身重量相當，遠高于其他干燥劑。由于其價格適中，安全和衛生，因此它是許多保健產品，藥品和生物干燥劑的較好選擇。

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，蒙脫石干燥劑

3. Montmorillonite desiccant

干燥劑被廣泛用于醫療保健，食品包裝，光學儀器，電子產品，軍用產品，民用產品和其他不能被油或天氣密封的產品。由于使用純天然原料膨潤土，具有吸附能力強，吸附速度快，無味無毒，無環境污染，無接觸腐蝕，綠色環保，無味無毒，無害的特點。對人體具有良好的吸附性能，吸附活性，靜態除濕和除臭功能。

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，生石灰干燥劑

4. Quicklime desiccant

高中化學課上曾討論過生石灰，其主要成分是氧化鈣，通過化學反應達到吸水，具有不可逆性。常見的是在“雪糕”中使用這種干燥劑。另外，它也常用于電器，皮革，服裝，制鞋，茶葉等。但是，由于生石灰屬于強堿，因此具有很強的腐蝕性，有時老年人和兒童的眼睛受傷，因此逐漸被淘汰。

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，氯化鈣干燥劑

5. Calcium chloride desiccant

氯化鈣主要以碳酸鈣和鹽酸為原料，并通過反應合成，過濾，蒸發濃縮，干燥等工藝進行精制。在食品工業中用作鈣強化劑，螯合劑，固化劑，干燥劑等。同時，還可以用作氣體的干燥劑，生產醚，醇，丙烯樹脂等的脫水劑。氯化鈣為多孔性塊狀，顆粒狀或蜂窩狀原料，無味，味微苦，溶于水，無色。

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.
