产品名称

催化剂级纳米氧化锌

产品编号
产品描述
  催化剂专用纳米氧化锌具有抗紫外线、光催化和杀菌防霉等特殊功效。产品无毒无害,是一种新型光催化产品首选的纳米氧化锌。室内无光条件下即可对有机物、甲醛、染料等进行分解,因此纳米氧化锌在催化净化方面的应用是值得我们关注的。
  催化剂的发展应是高效化、低腐蚀化、纳米化、环保化。高效可以用量更少,低腐蚀可减少对设备的损害,纳米化可使金属氧化物催化剂效率更高,环保化有益于健康和环境友好。
  催化剂在化工生产中具有重要而广泛的应用,生产化肥、农药、多种化工原料等都要使用催化剂。
  在化工生产、科学家实验和生命活动中,催化剂都大显身手。例如,硫酸生产中要用五氧化二钒作催化剂。由氮气跟氢气合成氨气,要用以铁为主的多组分催化剂,提高反应速率。在炼油厂,催化剂更是少不了,选用不同的催化剂,就可以得到不同品质的汽油、煤油。化工合成酸性和碱性色可赛思催化剂。汽车尾气中含有害的一氧化碳和一氧化氮,利用铂等金属作催化剂可以迅速将二者转化为无害的二氧化碳和氮气。酶是植物、动物和微生物产生的具有催化能力的蛋白质,生物体的化学反应几乎都在酶的催化作用下进行,酿造业、制药业等都要用催化剂催化。
