硬脂酸是工业中用途中非常广泛的化工原料，在很多行业中都有用到硬脂酸，其发挥了重要的作用。但是硬脂酸在使用中需要注意些事项才能够使其发挥很大的作用，下面氢氧化钾厂家就为大家介绍一下我们在使用它的过程中应该注意些什么。

Stearic acid is a widely used chemical raw material in industry. Stearic acid is useful in many industries and plays an important role. However, stearic acid needs to pay attention to some matters before it can play a great role. The potassium hydroxide manufacturer will introduce what we should pay attention to when using it.

1、在制造PVC透明制品时，硬脂酸的添加量量应小于等于0.5份，否则影响PVC透明制品的透明度；

1. When manufacturing PVC transparent products, the amount of stearic acid should be less than or equal to 0.5 phr, otherwise the transparency of PVC transparent products will be affected;

2、严格控制硬脂酸在铅盐复合稳定剂中的添加量，不可过多或过少，过少没效果，过多会出现塑化现角，而且会对润滑体系产生影响，降低其机械强度；

2. Strictly control the amount of stearic acid added in the lead salt composite stabilizer. Do not add too much or too little. Too little has no effect. Too much will lead to plasticizing corner, and will affect the lubricating system, reducing its mechanical strength;

3、在添加到钙锌复合热稳定剂体系中时，要求硬钙与硬锌及其他助剂的比例要合适合理，硬钙比例太低，会造成初期热稳定效能不好，比例太高，优惠造成PVC制品易发黄，耐候性差的结果；

3. When adding to the calcium-zinc composite heat stabilizer system, it is required that the ratio of hard calcium to hard zinc and other additives should be appropriate and reasonable. Too low ratio of hard calcium will lead to poor thermal stability at the initial stage, too high ratio, and preferential treatment will result in PVC products prone to yellowing and poor weather resistance;

4、硬脂酸的添加会影响到发泡剂分解的温度高低，纯AC发泡剂正常分解温度为211℃，但是如果添加了硬脂酸，其分解温度会下降到162℃，所以在添加使用硬脂酸时可适当增加稳定剂的添加量；

4. The addition of stearic acid will affect the decomposition temperature of foaming agent. The normal decomposition temperature of pure AC foaming agent is 211 ℃, but if stearic acid is added, its decomposition temperature will drop to 162 ℃, so the amount of stabilizer can be appropriately increased when adding stearic acid;

以上几点就是关于硬脂酸使用中需要注意的几点事项，大家一定要多加注意，不然事倍功半。当然很关键的事情就是使用，对此产品您有什么要咨询的，就来我们网站http://www.jinhao360.com吧！

The above points are the matters needing attention in the use of stearic acid. You must pay more attention to them, or you will get half the result with twice the effort. Of course, the key thing is to use security. If you have any questions about this product, please come to our website http://www.jinhao360.com Come on!
