1，硅膠干燥劑

1. Silica gel desiccant

其原料是一種無色，無味，，化學(xué)性能穩(wěn)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(shè)備等。其功能是在儲存和運(yùn)輸過程中控制環(huán)境的相對濕度，以防止物品受潮，發(fā)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

它由植物纖維制成，并經(jīng)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(jié)省空間并且方便實(shí)用。它的吸濕能力與其自身重量相當(dāng)，遠(yuǎn)高于其他干燥劑。由于其適中，和衛(wèi)生，因此它是許多保健產(chǎn)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(yī)療保健，食品包裝，光學(xué)儀器，電子產(chǎn)品，軍用產(chǎn)品，民用產(chǎn)品和其他不能被油或天氣密封的產(chǎn)品。由于使用原料膨潤土，具有吸附能力強(qiáng)，吸附速度快，無味，無環(huán)境污染，無接觸腐蝕，綠色環(huán)保，無味，無害的特點(diǎn)。對人體具有良好的吸附性能，吸附活性，靜態(tài)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(xué)課上曾討論過生石灰，其主要成分是氧化鈣，通過化學(xué)反應(yīng)達(dá)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(qiáng)堿，因此具有很強(qiáng)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(yīng)合成，過濾，蒸發(fā)濃縮，干燥等工藝進(jìn)行精制。在食品工業(yè)中用作鈣強(qiáng)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(chǎn)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.
