甘油即丙三醇，為無色味甜澄明黏稠液體。無臭，有暖甜味。能從空氣中吸收潮氣，也能吸收硫化氫、氰化氫和二氧化硫。對(duì)石蕊呈中性。長(zhǎng)期放在0℃的低溫處，能形成熔點(diǎn)為17.8℃有光澤的斜方晶體。
Glycerol, also known as glycerol, is a colorless, sweet, clear, and viscous liquid. Odorless, with a warm and sweet taste. It can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide, and sulfur dioxide. Neutral to litmus. Long term exposure to a low temperature of 0 ℃ can form shiny rhombic crystals with a melting point of 17.8 ℃.
丙三醇是甘油三酯分子的骨架成分。當(dāng)人體攝入食用脂肪時(shí)，其中的甘油三酯經(jīng)過體內(nèi)代謝分解，形成甘油并儲(chǔ)存在脂肪細(xì)胞中。因此，甘油三酯代謝終產(chǎn)物便是甘油和脂肪酸。那么甘油在化學(xué)工業(yè)及輕工業(yè)有哪些應(yīng)用呢？下面
氫氧化鉀廠家為您分析：
Glycerol is the backbone component of triglyceride molecules. When the human body ingests edible fat, the triglycerides in it undergo metabolic decomposition in the body to form glycerol and store it in fat cells. Therefore, the end products of triglyceride metabolism are glycerol and fatty acids. So what are the applications of glycerol in the chemical and light industries? The following potassium hydroxide manufacturer will analyze for you:
1、甘油可應(yīng)用于樹脂工業(yè)制造酯樹膠，酯樹膠又稱為甘油三松香酸酯或松脂膠?？梢杂酶视团c8.5~10.5份的松香在230~290℃之間酯化而成，可獲得比原來的松香更硬、更接近于中性而且更能抗水的酯膠，在工業(yè)上有很廣泛的用途。
1. Glycerin can be used in the resin industry to manufacture ester gum, which is also called glycerol trisrosin ester or rosin gum. It can be esterified with glycerol and 8.5~10.5 parts of rosin between 230~290 ℃ to obtain ester gum that is harder, closer to neutral, and more water resistant than the original rosin. It has a wide range of industrial applications.
2、在涂料工業(yè)中用以制取各種醇酸樹脂、聚酯樹脂、縮水甘油醚和環(huán)氧樹脂等。以甘油作為原料制成的醇酸樹脂是良好的涂料，可以代替快干漆和磁漆，并且絕緣性能良好，可應(yīng)用于電器材料。
2. Used in the paint industry to produce various alkyd resins, polyester resins, glycidyl ethers, and epoxy resins. Alkyd resin made from glycerol as a raw material is a good coating that can replace quick drying paint and enamel, and has good insulation performance, which can be applied to electrical materials.
3、甘油在化妝品產(chǎn)品中可作保濕劑、降粘劑、變性劑等使用，所以廣泛應(yīng)用于化妝品中（如面霜、面膜、洗面奶等）。使用甘油成分的護(hù)膚品能夠使皮膚保持柔軟，富有彈性，不受塵埃、氣候等損害而干燥，起到保濕、潤(rùn)膚的作用。
3. Glycerin can be used as humectant, viscosity reducer, denaturant, etc. in cosmetics, so it is widely used in cosmetics (such as face cream, facial mask, facial cleanser, etc.). Skincare products using glycerol ingredients can keep the skin soft, elastic, and dry from dust, climate, and other damage, playing a moisturizing and moisturizing role.
4、甘油大量應(yīng)用在玻璃紙的生產(chǎn)上作業(yè)增塑劑，賦予玻璃紙必要的柔軟性并防止玻璃紙破碎。在造紙工業(yè)上運(yùn)用于皺紙、薄紙、防水紙及蠟紙等。
4. Glycerin is widely used in the production of cellophane as a plasticizer to give cellophane the necessary softness and prevent cellophane from breaking. Used in the paper industry for wrinkled paper, thin paper, waterproof paper, and waxed paper.
5、在紡織工業(yè)中，甘油被用作紡線編織時(shí)的潤(rùn)滑劑，因?yàn)樗芡耆芙庠谒?，并且極容易在纖維上洗去，甘油應(yīng)用在印染工業(yè)中，對(duì)染色的滲透和均勻度均有幫助，一般用量為5%。復(fù)合甘油的衍生物可作為洗滌劑、滲透劑及乳化劑應(yīng)用。
5. In the textile industry, glycerol is used as a lubricant for spinning and weaving because it can completely dissolve in water and is easily washed off on fibers. When glycerol is used in the printing and dyeing industry, it helps to improve the penetration and uniformity of dyeing, with a general dosage of 5%. Derivatives of composite glycerol can be used as detergents, penetrating agents, and emulsifiers.
6、甘油在照相技術(shù)中主要作為膠片的增塑劑，可防止膠片龜裂和收縮。
6. Glycerin is mainly used as a plasticizer in photography to prevent film cracking and shrinkage.
7、橡膠制品浸在甘油中貯存，比暴露在空氣中貯存，在時(shí)間上可以延長(zhǎng)得很多。甘油在橡膠工業(yè)上作硫化介質(zhì)和潤(rùn)滑劑用。
7. Rubber products stored in glycerol can be stored for a much longer time than when exposed to air. Glycerin is used as a vulcanizing medium and lubricant in the rubber industry.
That's all for the application of glycerol (glycerol) in the chemical and light industries. We hope to provide you with good help. For more product information, please visit our website http://www.laiyanglicheng.com consulting service
