Description

微量元素添加剂碱式氯化锌的制备方法
技术领域：
本发明涉及一种微量元素添加剂碱式氯化锌的制备方法。
背景技术：
在当今的养殖中锌的应用是不可缺的，但一般都是用硫酸锌或氧化锌来作为锌元素添加剂，这两种锌元素存在的问题是吸收慢并且吸收率低，因此用量也大。而螯合锌(蛋氨酸锌等)虽然好则因价格过高难以推广应用。碱式氯化锌作为饲料应用，在解决养殖动物中要求锌吸收快、吸收率高、减少排泄物由于锌含量高对环境造成的污染并且价格不能过高等方面起到了积极的作用。以往碱式氯化锌的生产有用废锌生产的，也有用电镀版或线路版的蚀刻液中的锌来生产的，这些方法的缺点就是产品中含杂质较多，重金属含量过高处理很难，因此难以达到饲料卫生标准。
发明内容：
本发明所要解决的技术问题是，提供一种收率高、环境污染少、成本低、工艺简单、成品品质好、无杂质、卫生标准高的饲料添加剂微量元素碱式氯化锌的制备方法。
本发明的制备方法如下：
1、氧化锌与氯化锌以摩尔比为4∶1，在温度75-95℃下，控制PH值6-8，常压条件下反应1.5～3小时，生成碱式氯化锌；其反应如下：
ZnCl2+4ZnO+5H2O＝Zn5Cl2(OH)8+H2O
2、离心分离、水洗；
3、烘干、粉碎、包装成成品。
以此种方法来制备碱式氯化锌可以提高碱式氯化锌的纯度，因为在此种方法中利用氯化锌的酸性和氧化锌的碱性来直接进行中和反应，并不需要加入另外的促进反应剂，所以在最后的反应物中没有其他的副产物。本发明还具有工艺简单、收率高、成品品质好、无杂质、优于饲料卫生标准等优点。
具体实施方式：
实施例1：
反应步骤如下：4摩尔氧化锌加1摩尔氯化锌，在80℃±5℃的反应温度下，调节PH值为6.5～7.5，反应2～3小时，离心分离、水洗、烘干、粉碎、即可成成品。其中锌含量为60％。
实施例2：
反应步骤如下：4摩尔氧化锌与1摩尔氯化锌，在80℃～95℃反应温度下，控制PH值为6-8左右，反应1.5～2小时，生成碱式氯化锌，其中锌含量为61％。
用本添加剂按氧化锌用量30-60％喂公猪，可促进生长、提高抗病能力；延长种猪繁殖使用寿命；
用本添加剂按氧化锌用量30-60％喂肥育猪可促进生长，改善料肉比，改善肉色，使猪皮肤红润，毛色光亮。
用本添加剂按氧化锌用量30-60％饲喂乳仔猪，可提高抗应激能力与免疫力，促进生长，预防乳仔猪下痢，显著提高饲料的经济价值；
用本添加剂按氧化锌用量30-60％喂肉禽可使生长速度提高，料肉比下降，增强羽毛光泽度，提高其应激能力，降低死亡率。
用本添加剂按氧化锌用量30-60％喂水产动物，可增强免疫力，降低发病率与死亡率，促进生产，减少疾病发生，减少水溶性损失提高饲料利用率。
