硬脂酸是工業中用途中非常廣泛的化工原料，在很多行業中都有用到硬脂酸，其發揮了重要的作用。但是硬脂酸在使用中需要注意些事項才能夠使其發揮很大的作用，下面氫氧化鉀廠家就為大家介紹一下我們在使用它的過程中應該注意些什么。

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透明制品時，硬脂酸的添加量量應小于等于0.5份，否則影響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、嚴格控制硬脂酸在鉛鹽復合穩定劑中的添加量，不可過多或過少，過少沒效果，過多會出現塑化現角，而且會對潤滑體系產生影響，降低其機械強度；

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、在添加到鈣鋅復合熱穩定劑體系中時，要求硬鈣與硬鋅及其他助劑的比例要合適合理，硬鈣比例太低，會造成初期熱穩定效能不好，比例太高，優惠造成PVC制品易發黃，耐候性差的結果；

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、硬脂酸的添加會影響到發泡劑分解的溫度高低，純AC發泡劑正常分解溫度為211℃，但是如果添加了硬脂酸，其分解溫度會下降到162℃，所以在添加使用硬脂酸時可適當增加穩定劑的添加量；

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;

以上幾點就是關于硬脂酸使用中需要注意的幾點事項，大家一定要多加注意，不然事倍功半。當然很關鍵的事情就是使用，對此產品您有什么要咨詢的，就來我們網站http://www.shrisa.cn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.shrisa.cn Come on!
