1、 1 印行年月 94 年 10 月 本標準非經本局同意不得翻印 中華民國國家標準 CNS 總號 類號 ICS 71.060.01 K11613380經濟部標準檢驗局印行 公布日期 修訂公布日期 61 年 6 月 27 日 93 年 7 月 22 日 (共 2 頁 )硬脂酸鋁(工業級) Industrial grade aluminum stearate 1. 適用範圍:本標準適用於工業級硬脂酸鋁。 2. 品質 2.1 化學成分:約為 A1(C18H35O2)3 nAl2O3。 2.2 外觀:白色粉末。 2.3 比重: 1.080.02。 2.4 熔點: 115 至 155。 2.5 顆粒細度:

2、全部通過試驗篩 0.125mm CNS 386試驗篩。 2.6 灰分: 5.6 至 7.4%。 2.7 溶解性:不溶於水,微溶於乙醇,鹼及丙酮,溶於汽油及松節油,與苯及甲苯混合則呈膠狀。 2.8 水分: 1%以下。 2.9 游離酸: 10%以下。 3. 檢驗 3.1 外觀:依目視判定之。 3.2 比重:用分析天平稱 50mL 之比重瓶記下重量設為 A,充滿 25之水稱重設為B,將水倒出,並烘乾該比重瓶,加入 1 至 2g 之試樣,稱重設為 C,加水以漩渦運動方式濕潤之,再盛滿 25之水,稱重設為 D,則 試樣比重= d)CD()AB()AC(式內, d=水 25時之比重 3.3 熔點:取一直徑

3、 0.75mm 測定熔點之毛細管,置入試樣 0.5cm 高,綁于溫度計側,使管底與溫度計之水銀球齊平,該溫度計係插入一有孔之塞中,將此附溫度計及毛細管之塞,塞入盛有適當量甘油之 D 型管中,加熱 D 型管使溫度以 3 /分鐘之速率上昇,注意細管中之試樣,記錄其開始熔化時之溫度,即為試樣之熔點。 3.4 顆粒細度:稱取 30g 試樣放入試驗篩 0.125mmCNS 386 中先濕潤之,再以水沖洗 5 分鐘後,以目視判斷之。 3.5 灰分:稱取 1 至 2g 之試樣 (精確至 0.1mg)置入燒過已稱量之瓷坩堝中先徐徐加熱趕走揮發物,再於 850 至 900之廻熱爐中强熱至恒量,則: 灰分, 10

4、0試樣量灰分量 2 CNS 3380, K 1161 3.6 溶解性:預備 8 個 20mL 之乾淨試管,各置入 1g 之試樣,再分別注入 10mL 之水、乙醇、 6N NaOH、丙酮、汽油、松節油、苯及甲苯,塞住瓶口,間斷振盪兩小時,靜置半小時後以目視判斷之 (必要時倒出一部分澄清溶液,蒸發後判斷之 )。 3.7 水分:依 CNS 13106化學製品水分測定法之規定試驗之。 3.8 游離酸:依 CNS 13568化學製品酸價、皂化價、酯價、碘價、羥價及不皂化物試驗法之規定試驗之。 4. 包裝及標示:應有適當之 包裝。包裝須註明品名、淨重、毛重、製造日期及製造廠名等。 引用標準: CNS 386 試驗篩 CNS 13106 化學製品水分測定法 CNS 13568 化學製品酸價、皂化價、酯價、碘價、羥價及不皂化物試驗法
