1^F→saltlake: 可是酸溶於水似乎是放熱反應用冷水才有220.136.211.205 02/10 18:23

2^F→saltlake: 利反應進行不是嗎? 當然油脂易溶於熱水220.136.211.205 02/10 18:23

3^F→saltlake: 所以這兩要求彼此有衝突220.136.211.205 02/10 18:23

4^F→saltlake: 怎樣做才比較適當?220.136.211.205 02/10 18:24

9^F→saltlake: 網路查了酸的比重大於水所以要把酸倒入220.136.210.101 02/15 16:53

10^F→saltlake: 水中使酸一邊沉降於水一邊放熱比較安全?220.136.210.101 02/15 16:53

11^F→saltlake: 那麼就要先倒大量熱水於管路再緩換加入220.136.210.101 02/15 16:54

12^F→saltlake: 少量的酸以策安全? 這樣熱水軟化油脂等220.136.210.101 02/15 16:54

13^F→saltlake: 污物然後加入的酸被水稀釋後繼續與污物220.136.210.101 02/15 16:55

14^F→saltlake: 反應以分解之? 但是這樣酸沒有直接接觸220.136.210.101 02/15 16:56

15^F→saltlake: 管壁黏著的汙物去汙力會否不夠?220.136.210.101 02/15 16:56

16^F→saltlake: 可是仙家酸再加熱水又會有突沸的危險220.136.210.101 02/15 16:56
