产品特点及用途 |
活性氧化锌为白色或微黄色球状微细粉末,密度5.47g/cm3,熔点1800℃,不溶于水,溶于酸,碱氯化铵和氨水中。在潮湿空气中二氧化碳生成碱式碳酸锌。其最大特征是粒径50-100纳米,比间接法氧化锌和直接法氧化锌有更大的比表面积,在应用中具有更高活性和良好分散性。 活性氧化锌的折射率与天然橡胶非常相近,因此能让硫化产品的颜色更清澈透明。 应用: 1、具有滚动性好,分散性优良的特点,加上它粒径小,结构轻而疏松,氮吸附比表面积大,使它在用作硫化活性剂时,在胶料中分布均匀,与硫化氢的接触面积大,进行界面反应机遇较大,再加上本产品有活性物质的助催作用,使氧化锌转化为硫化锌的转化率高。因此作为合成橡胶的硫化促进剂和良好的补强剂,是普通氧化锌用量的50-70%。 2、在橡胶工业中用作紫外线的稳定剂,能使聚乙烯的耐大气性得到较好的改善。 3、与树脂酸发生反应而制得的锌树脂,可用来生产快干油墨,具有良好的着色作用。 4、制成的氧化锌脱硫剂,具有比表面积大,穿透硫容高,机械强度高,堆积隙大,床层压降小的特性。广泛应用于全成氨,甲醇和制氢等工业原料气,油的深度脱硫净化过程。在一定温度和压力下能把气体中微量的硫化氢,有机硫浓度有效的降低。

Activity of zno is white or light yellow fine spherical powder, 5.47 g/cm3 density, melting point 1800 ℃, insoluble in water, soluble in acid, alkali and ammonium chloride and ammonia. Carbon dioxide is generated in the moist air alkaline zinc carbonate. Its biggest feature is the particle size of 50-100 nm, than the indirect method zinc oxide and the direct method zinc oxide has larger specific surface area, has higher activity and good dispersibility in the application. Activated zinc oxide of the refractive index with natural rubber very close, so can make the color of the vulcanizate more clear and transparent. Application: 1, has a good rolling, good dispersion characteristics, coupled with its small size, light and loose structure, nitrogen adsorption specific surface area is big, make it when used as a curing agent, distributed evenly in the rubber, large contact area with hydrogen sulfide, opportunities for interface reaction is bigger, plus this product has helped push role of active material and the transformation of zinc oxide to zinc sulfide conversion rate is high. Therefore as synthesis of rubber vulcanization accelerator and good reinforcing agent, is 50-70% of normal dosage of zinc oxide. 2, used in rubber industry, ultraviolet stabilizer, get good at to make polyethylene atmosphere to improve. 3, react with the resin acid zinc made by resin, can be used to produce quick-drying inks, has the good color effect. 4, made of zinc oxide desulfurization agent, has a large specific surface area, through the high sulfur capacity, high mechanical strength, the accumulation of gap is big, small bed pressure drop characteristics. Widely used Yu Quancheng ammonia, methanol and hydrogen making industrial raw materials such as gas, oil purification depth desulphurization process. Under a certain temperature and pressure trace amounts of h2s in the gas, effectively reduce the organic sulfur concentration. |
