Product application
Hard surface cleaning
左圖表示硬質表面清洗中的實例,各種表面活性劑對瓷磚表面清洗擦拭20次后油污殘留率的對比, SECOL對硬質表面清洗后油污去除率數值比其他非離子表活的油污去除率高。
The figure on the right shows an example of hard surface cleaning of various surfactants on ceramic tile surfaces. SECOL series show excellent soil removal efficiency compared with other types of non-ionic surfactants.
Wool Scouring
左圖表示羊毛清洗中的應用實例,實施該試驗時未添加純堿,表示的是每噸原羊毛洗滌到含油率低于0.5%所需要的表面活性劑的干克數。 SECOLS的羊毛清洗力高于天然醇瞇和NPE的清洗力,洗滌劑耗量低,手感出眾。
The figure on the right shows an example of application in wool scouring. No sodium carbonate was added to the test. Lab tank scouring results on 70s wool demonstrates wool scouring performance of SECOL is better than that of primary alcohol ethoxylates and NPE.
Formulations concentrated laundry detergent
左圖參考文獻[1]中配方(F1),并依據其備至方法配制濃縮洗衣液。將右表各配方樣品一式3份分別于室溫、(40士2)℃、(0士2)℃條件下放置一個月,同時做(40土2)℃和(-5土2)℃條件下各放置24小時的冷熱循環實驗。結果顯示,各樣品在考察前后的狀態無明顯差異,說明仲醇醚 SECOL-90、SECOL-70與實驗配方用各原料具有良好的配伍性。左圖還表明, SECOL-90、SECOL-70代替AEO-9、AEO-7或者異構醇醚用于濃縮洗衣液配方可以降低配方中溶劑的添加量。
Concentrated laundry detergents are formulated according to ref[1]. These sam-ples were stored at room temperature, (40+2)°Cand(0±2)℃ for one month，respectively, and were subjected to cold and heat cycles for24 hours at (40±2)°C and (-5±2)°C respectively. The results show that there was no significant difference in the state of the samples before and after the tests, which indicates that secondary alcohol ethoxylates SECOL-90 and SEC-OL-70 had good compatibility with other raw materials. The results also indicate thatSECOL-90 and SECOL-70. instead of AEO-9, AEO-7 used to concentrate laundry liquid formula can reduce the amount ofsolvent added in the formula.
Detergency
如左圖所示,所采用濃縮洗衣液配方體系中,3種醇醚對國標皮脂污布的去污力沒有明顯差異, SECOL仲醇產品和支鏈醇醚對國標碳黑污布的去污力基本相當,明顯高于直鏈醇。此外,還可以看出,溶劑在配方中對產品去污力的提高確實沒有明顯作用,設計配方時可最大程度地降低溶劑用量。
As shown in the chart. there is no signifi-cant difference in the detergency of three types of alcohol ethoxylates to sebum cloth,and the detergency of SECOL products and branched C13 ethoxylate to carbon black cloth are almost the same, higher than oleo ethoxylate. The results also indicate that solvents play minimum role of detergency in formulations thus their doeage should be limited in laundry formulations.
