4、因本身具有活性,应用非常方便,干法、半干法生产阳离子淀粉,在一定温度下ETA与淀粉直接混合,就可得到阳离子淀粉,生产设备投资少,工艺流程简单,生产成本较低。
5、用活性固体阳离子醚化剂生产的阳离子淀粉对造纸设备腐蚀性较小。
6、因含量高、杂质少、本身具有活性,特别适应生产0.03-0.5以上高取代度阳离子淀粉,且成本低。
活性固体阳离子醚化剂它具有广泛用途:
它可以与多种基质如淀粉、纤维素、瓜尔胶、聚丙烯酰胺等反应能生产多种产品。这些产品广泛用于下列工业领域。
一、造纸行业:GTA与淀粉反应生产阳离子淀粉,大量用于造纸工业作为助留助滤剂,干、温增强剂及表面施胶剂等,ETA既适应于阳离子淀粉专业生产厂使用,又可易于造纸行业自制阳离子淀粉。
二、石油工业:石油化学通过应用证明,油田化学品正由过去的阴离子体系、非离子体系向具有阳离子的复合体系过渡,ETA可与具有负电性的多种天然高分子及合成高分子反应而进行阳离子季胺化改性,而赋予它们新的性能与应用领域,在石油工业中,ETA本身是一种性能优异的粘土稳定剂,由ETA与其它基质反应生成的产物在油田更为广泛应用,在钻井泥浆、采油用剂、油田污水处理方面效果更为突出。
三、水处理工业:水中各悬浮物呈阴(负)电性,阳离子高分子絮凝剂在污水净化中广泛应用,与无机絮凝剂相比,有机阳离子高分子絮凝剂具有用量少、絮凝速度快、受共存盐,PH及温度等因素影响小,生成污泥量小,且易处理、成本低,阳离子高分子絮凝剂是在实际应用中最有效,也是极为重要的絮凝剂,与ETA反应生成的阳离子高分子絮凝剂,在水处理中是一次技术更新换代,将有更为广泛的用途。
四、日用化学工业:GTA与纤维素反应生成的季胺化合物是二合一洗发露中重要的调理剂,应用于各种化妆品,对皮肤和头发没有刺激和损伤,与其它阴离子表面活性配制性较好。ETA与瓜尔胶反应生成的阳离子瓜尔胶,在日用化学品中应用广泛。

Active solid cationic etherification agent (hereinafter referred to as GTA)
Active solid cationic etherification agent (hereinafter referred to as GTA) is a kind of multi-functional fine chemical products, the chemical name: 2, 3-epoxy with propyl three methyl chloride, under normal temperature for small white granular solid, strong water imbibition, that could melt, GTA molecule containing quaternary ammonium salt and the base and the epoxy groups, it contains nitrogen compounds with activity, is extremely easy to produce chemical reaction, and get the DuoZhong ammonium containing season and chemicals. Especially with the modified starch production without any additives, direct and starch GTA stirrer, can get any substitution degree modified starch, process simple operation, the equipment investment is less. Active solid cationic etherification agent has the following advantages:
1, products, high purity content in 96% above, little impurity, epoxy residues in less than 3 PPM is no residual solvents, a tasteless, dry thoroughly.
2, and starch, etc of the matrix of the reaction rate is high, superior conditions in response rate can amount to 100%.
3, active solid cationic etherification agent of small molecular weight, under the same conditions only 80% of the amount of similar products to join.
4, because itself has activity, application is very convenient, dry, half dry process production cationic starch, in certain temperatures GTA and starch mixed directly, can get cationic starch, the production equipment is less investment, technological process simple, the production cost is low.
5, by active solid cationic etherification agent production of paper cation starch equipment corrosive smaller.
6, for content high, the little impurity, itself has activity, especially for producing 0.03-0.5 high above the substitution degree cationic starch, and low cost.
Active solid cationic etherification agent it widely used:
It can and DuoZhong substrate such as starch, cellulose, guar gum, PAM and reaction can DuoZhong production products. These products are widely used in the industrial field.
A, paper making industry: GTA and starch producing cationic starch reaction, a lot is used for making paper industry as retention aid filter aid agent, dry, warm strengthening agent and surface sizing agent and so on, to adapt in both GTA cation starch professional production factory use, but also easy to paper industry homemade cationic starch.
Second, the oil industry: petroleum chemical through the application proved, oil field by the past chemicals is anion system, the ion system to the complex system have cationic transition, and has become negatively charged sexual GTA the DuoZhong natural polymer and synthetic polymer reaction and cationic season amination modification, and gives them new properties and the application field, in the oil industry, GTA itself is a kind of excellent performance clay stabilizer, by GTA and other matrix synthesis product in the oil field response is more widely used in drilling mud, oil, oil field with agent sewerage effect is more outstanding.
Three, water treatment industry: the water is suspended the Yin (negative) electrical, cationic polymer flocculant in sewage purification widely used, and the inorganic flocculant compared, organic cation polymer flocculant with consumption and flocculation speed, the coexistence of salt, PH and temperature influenced by such factors as small, generating less amount of sludge, and easy handling, low cost, cationic polymer flocculant in practical application is the most effective, is also extremely imp0rtant flocculating agent, and the reactions that produce GTA cationic polymer flocculant, in water treatment is a technical renewal and will have more extensive use.
Four, daily chemical industry: GTA and cellulose reaction of the generation of quaternary ammonium compounds is imp0rtant in my champoo conditioners, applied in all kinds of cosmetics, no stimulation to the skin and hair and damage, and other anion active surface preparation sex is good. GTA and guar gum reaction generated cationic guar gum, in daily chemical used widely.
