            硬脂酸呈白色蠟狀透明固體或微黃色蠟狀固體,能分散成粉末,微帶牛油氣味。那么硬脂酸的基本信息您了解多少呢?下面氫氧化鉀廠家為您講解一番。
            Stearic acid is a white waxy transparent solid or yellowish waxy solid, which can be dispersed into powder with a slight butter smell. How much do you know about stearic acid? The following potassium hydroxide manufacturer will explain it for you.
            為白色或類白色有滑膩感的粉末或結晶性硬塊,其剖面有微帶光澤的細針狀結晶;有類似油脂的微臭,無味。本品在氯仿或乙醚中易溶,在乙醇中溶解,在水中幾乎不溶。
            It is white or off white slippery powder or crystalline hard block, and its cross-section has fine needle like crystals with slight luster; It has a slight odor similar to oil and is tasteless. This product is easily soluble in chloroform or ether, soluble in ethanol, and almost insoluble in water.
            本品的凝點(附錄ⅥD)不低于54℃。碘值本品的碘值(附錄ⅦH)不大于4。酸值本品的酸值(附錄ⅦH)為203~210。硬脂酸易與鎂離子和鈣離子反應生成硬脂酸鎂和硬脂酸鈣(白色沉淀)。
            The freezing point (Appendix VI d) of this product shall not be lower than 54 ℃. Iodine value the iodine value of this product (Appendix Ⅶ h) is not more than 4. Acid value the acid value of this product (Appendix Ⅶ h) is 203 ~ 210. Stearic acid is easy to react with magnesium ions and calcium ions to form magnesium stearate and calcium stearate (white precipitate).
            本品廣泛用于化妝品、塑料增塑劑、脫模劑、穩定劑、表面活性劑、橡膠硫化促進劑、防水劑、拋光劑、金屬皂、金屬礦物浮選劑、軟化劑、醫藥品及其他有機化學品。硬脂酸還可用作油溶性顏料的溶劑、蠟筆調滑劑、蠟紙打光劑、硬脂酸甘油脂的乳化劑等。
            This product is widely used in cosmetics, plastic plasticizers, release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproof agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and other organic chemicals. Stearic acid can also be used as a solvent for oil-soluble pigments, a wax pencil smoothing agent, a wax paper polishing agent, and an emulsifier for stearic glycerides.

            硬脂酸還廣泛應用于聚氯乙烯塑料管材、板材、型材、薄膜的制造,是聚氯乙烯的熱穩定劑,具有很好的潤滑性和較好的光、熱穩定作用。
            Stearic acid is also widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a heat stabilizer of PVC and has good lubricity and light and heat stability.
            在聚氯乙烯管材中應用,硬脂酸有助于防止加工過程中的“焦化”,在聚氯乙烯薄膜加工中是有效的熱穩定劑,同時可以防止暴曬所引起的成品薄膜變色。硬脂酸已成為填充改性母料的潤滑、增塑的功能助劑。
            In the application of PVC pipes, stearic acid helps to prevent "coking" during processing, is an effective heat stabilizer in the processing of PVC films, and can prevent the discoloration of finished films caused by exposure to the sun. Stearic acid has become a functional additive for lubrication and plasticization of filling modified masterbatch.
            硬脂酸可有效的提高無機粉體包覆活化效果,增加物料的流動性,對于無機粉體占份數的物料要求熔體流動速率較大時,適當提高硬脂酸的含量,可明顯增加物料的熔體流動速率。
            Stearic acid can effectively improve the coating and activation effect of inorganic powder and increase the fluidity of materials. When the melt flow rate of materials with a large proportion of inorganic powder is required, appropriately increasing the content of stearic acid can significantly increase the melt flow rate of materials.
            但是,硬脂酸在填充改性母料中的用量也有極限值,一般控制在總質量的1%左右。添加量過大,會引起塑料制品的質量性能下降,還會使塑料制品生產設備的模唇位置等機械裝置出現黏糊狀物,影響生產效率和產品質量。所以您了解了嗎?更多事項就來我們網站http://www.festivalmatsuri.com咨詢吧!
            However, the amount of stearic acid in the filling modified masterbatch also has a limit value, which is generally controlled at about 1% of the total mass. If the amount of additive is too large, the quality performance of plastic products will decline, and the mechanical devices such as the die lip position of the plastic product production equipment will appear sticky substances, which will affect the production efficiency and product quality.
