粘度 Viscosity

　　圖中表示各種非離子表面活性劑溫度和粘度的關系, SECOL產品與王基酚系列及伯醇系列相比,具有更低的粘度,日常使用更方便。

　　Fig shows the relationship between viscosity of various nonionic surfactantsand temperatures. SECOL exhibits lowerviscosity compared to nonylphenols andprimary alcohols, thus convenient for handling.

流動點 Pour point

　　右圖表示各種非離子表面活性劑的流動點和HLB的關系。SECOL系列產品的流動點均比伯醇要低，和壬基酚系列相比，在HLB高于10時二者是相近的，在HLB低于10時，SECOL產品是遠低于壬基酚系列產品。

　　Fig, shows the relationship betweenpour points of various nonionic surfactants and HLB values, The SECOLseries nonionic surfactants have extremely low pour points compared toprimary alcohols. The nonylphenols show the same pour points as SECOL in theHLB range above 10, but their pourpoints are much higher in the HLB rangebelow 10.

耐酸堿度 Chemical stability

SECOL系列產品對酸堿穩定，可以在很寬的PH區域使用。

（1）耐酸度

　　在10%硫酸水溶液中溶解5%SECOL-90，回流煮沸4小時后仍均勻透明，其性能沒有變化。

（2）耐堿性

　　在5%氫氧化鉀水溶液中溶解1%SECOL-90，回流煮沸4小時后仍均勻透明，其性能沒有變化。

　　Solution of 1% SECOL-90 in 5% aqueous potassium hydorxide is boiled under reflux. After 4 hours,the solution is uniformly clear and its performance unchanged.

濕潤力 Wettability

　　SECOL系列產品與其他產品相比，具有更加優秀的濕潤力，可在較寬的溫度范圍使用。在低濃度下，具有更優秀的濕潤力。

　　右圖表示對羊毛的濕潤力和HLB關系。

　　Compared to other surfactants,SECOL surfactants have excellent wetting power over a wide temperature range.At low concentrations,they have better wetting power.

木棉潤濕時間

　　右圖是各種表面活性劑不同濃度對木棉的潤濕時間們可以看出SECOL系列品比NP-10和AEO-9具有更低濃度的潤濕優勢。

　　The figure on the right shows the wetting time of kapock under different concentrations of various surfactants,It can be seen that SECOL series products have lower concentraton wetting advantages than NP-10and AEO-9.

乳化力 Emulsifying power

　　如右圖所示，相同碳原子數，相同EO加成數，SECOL系列的乳化力遠優于AEO-9和AEO-7。

　　Figure on the right, with the same number of carbon atoms and EO addition the emulsifying power of the SECOL series is much better than that of AEO-9 andAEO-7.

發泡形狀 Foaming property

　　如右圖所示,采用ROss- Miles法進行的發泡性狀, SECOL具有獨特的泡質和良好的破泡性能。PO封端的 SECOL-EP系列更是表現了優良的低泡性能。

　　Figure shows the foaming property mea-sured by the Ross-miles method. SECOL surfactants have unique foaming properties and good foam breakability.
The SECOL-EP series demonstrates excellent low-foam properties.

去污力 Detergency

　　如右圖所示,相同碳原子數,相同EO加成數,SECOL系列對碳黑污布的去污力與其他產品相當。 SECOL-90對皮脂污布的去污力遠優于AEO-9,優于1309。

　　Figure on the right, with the same number of carbon atoms and the same EO addition number, the detergency of the SECOL series to the carbon black stain cloth is comparable to that of other products SECOL-90 is superior to AEO-9 and 1309in detergency of sebum cloth.

仲醇聚氧乙烯醚

Secondary alcohol ethoxylate --- How it is better?

具有多方面優越性能的非離子表面活性劑。

One of the top-tier non-ionic surfactants, with well-rounded properties.

環保型 Environmental protection

　　SECOL系列產品是直鏈型仲醇表面活性劑,生物分解性好,因此排水容易處理。右圖是 SECOL-90和NP-10,TO-9產品的江河降解試驗。根據GB/T15818檢測SECOL系列產品初級降解率是99%。

　　Fig shows the relationship between viscosity of various nonionic surfactantsand temperatures. SECOL exhibits lowerviscosity compared to nonylphenols andprimary alcohols, thus convenient for handling.

River degradation experiment
　　Since SECOL alcohols are linear in structure, they are highly biodegradable and are easily degraded in wastewater.
