三聚磷酸钠主要作用可概括几点

发布来源:http://www.xhczhushu.com    更新时间:2022-12-05 点击数:

三聚磷酸钠是洗涤剂中不可缺少的优良助剂,多数洗涤剂中的含量为10~50%。凯时k66官方网站厂家认为其主要作用可概括为如下几点:
Sodium tripolyphosphate is an indispensable excellent auxiliary agent in detergents, and the content of most detergents is 10-50%. Potassium hydroxide manufacturers think that its main functions can be summarized as follows:
(1)对金属离子的螯合作用:日常洗涤用水中,一般都含有致硬金属离子(主要是Ca2+、Mg2+)。在洗涤过程中,它们将与肥皂或洗涤剂中的活性物形成不溶性金属盐,这样,不仅使洗涤剂的耗量增加,而且使洗后的织物具有令人不快的暗灰色。三聚磷酸钠具有螯合致硬金属离子的优异性能,从而可消除这些金属离子的不利影响。
(1) Chelation of metal ions: water for daily washing generally contains hard metal ions (mainly Ca2+, Mg2+). In the washing process, they will form insoluble metal salts with the active substances in soap or detergent, which will not only increase the consumption of detergent, but also make the washed fabric unpleasant dark gray. Sodium tripolyphosphate has excellent properties of chelating hard metal ions, which can eliminate the adverse effects of these metal ions.
(2)提高胶溶、乳化和分散的作用:污垢中常含有人体分泌物(主要是蛋白质和脂肪类物质),也含有来自外界的沙土、尘埃等。而三聚磷酸钠对蛋白质具有膨润、增溶作用而起到胶溶的效果;对脂肪类物质则可起到促进乳化的作用;对固体粒子则有分散悬浮作用。
(2) Improve the functions of gel dissolution, emulsification and dispersion: dirt often contains human secretions (mainly proteins and fats), as well as sand and dust from outside. However, sodium tripolyphosphate has swelling and solubilizing effects on protein, which has the effect of colloidal dissolution; For fat substances, it can promote emulsification; It can disperse and suspend solid particles.\

(3)缓冲作用:三聚磷酸钠具有较大的碱性缓冲作用,使洗涤溶液pH值保持在9.4左右,从而有利于酸性污垢的去除。
(3) Buffer effect: sodium tripolyphosphate has a greater alkaline buffer effect, keeping the pH value of the washing solution at about 9.4, which is conducive to the removal of acid dirt.
(4)防止结块的作用:粉状合成洗涤剂具有吸湿性,如存放在湿度较大的地方,就要发生结块现象。结块的洗涤剂使用时为不便。而三聚磷酸钠吸水后形成的六水合物,具有干爽的特性。当洗涤剂配方中有大量三聚磷酸钠时,就能起到防止因吸潮而造成的结块现象,保持合成洗涤剂的干爽粒状。
(4) Prevention of caking: powdered synthetic detergent is hygroscopic. If it is stored in a place with high humidity, caking will occur. It is inconvenient to use caked detergent. However, the hexahydrate formed by sodium tripolyphosphate after absorbing water is dry and refreshing. When there is a large amount of sodium tripolyphosphate in the detergent formula, it can prevent the caking phenomenon caused by moisture absorption, and keep the dry granular shape of synthetic detergent.
