通过去污实验,发现在活性成分相同时,洗衣粉的去污力比洗衣膏平均高出47.5%.对不同配方和工艺进行考察,证明这种去污力的差异不是烷基苯磺酸中的游离油造成的,也不是填充剂无机盐的含量不同引起的,而是三聚磷酸钠发生水解所致.料浆烘干后,螯合力平均提高了27.8%.三聚磷酸钠在料浆中发生水解,而在烘干时又重新聚合.三聚磷酸钠更适合在粉状洗涤剂中使用. 相似文献

生化需氧量可衡量洗涤剂中难降解有机成份对生态环境的影响程度,本文抽取了5种品牌洗涤剂样品(3种洗衣粉、2种洗衣液),通过稀释法测定1 g/L洗涤废水的生化需氧量BOD_5。首先根据测得的化学需氧量CODCr值来计算稀释倍数,根据不同的稀释倍数测定BOD_5,得到:3个样品(2个洗衣粉和1个洗衣液)BOD_5在50 mg/L以内;2个样品(1个洗衣粉和1个洗衣液)BOD_5在200 mg/L左右。可见:1)5种品牌洗涤废水的排放适合其他排污单位的三级标准;2)不同品牌的洗衣粉和洗衣液BOD_5结果差别较大,建议加强宣传力度,鼓励企业优化洗涤产品的配方,引导居民合理选择安全环保的洗涤剂品种。 相似文献

我国的洗涤剂目前以石油产品为原料的合成洗涤剂居多,在合成洗涤剂中合成洗衣粉最多.在液体洗涤剂中餐洗最多.用液体皂洗涤衣物不仅可省下短缺的石油资源,能和水,还有生物降解好,安全性高,成本低,排污少等洗衣粉莫所及的优点,液体皂最大的缺陷是不耐硬水影响其去污,经过调整配方和改变使用方法能抑制钙皂的生成从而提高了去污力能达到洗衣粉的水平.多用液体皂就能多节约. 相似文献

按衣料用洗涤剂国家标准(GB/T 13174-2003)中去污力测定方法对3种标准污布进行了去污试验,发现标准规定的洗涤质量浓度0.2 g/L存在不足;在标粉质量浓度0.1 g/L~0.4 g/L下洗涤,其去污试验数据显示,洗涤差值随洗涤质量浓度的增加而增大,经精密度分析确定了洗涤质量浓度为0.3 g/L的试验洗涤浓度。通过对洗衣粉质量浓度为0.3 g/L洗涤实际去污力的测定,结果表明:质量浓度0.3 g/L下洗涤,洗衣粉在3块标准污布上洗涤结果的重复性和精密度均好于GB/T 13174-2003所规定的0.2 g/L。 相似文献

The adsorption of a mixture of cationic (c) and anionic (a) surfactants on cellulose fibers is highly dependent on the molar
ratio a/c with a maximum at a/c = 0.9. When a/c is > 1.1 the adsorption is negligible. The presence of nonionic surfactants
in the solution impairs the adsorption of the ionic species; this effect is stronger for nonionic surfactants with long alkyl
and polyglycol ether chains. The detergency—measured on WFK cotton cloth—is highest when a/c > 1 and decreases sharply when
a/c goes below 0.8. The antistatic effect for a formulated liquid detergent based on these principles was compared to one
commercial liquid detergent with softening and antistatic properties and one commercial detergent powder, and the test detergent
was shown to be a better antistatic agent on polyester, polyacrylonitrile and polyamide. The detergency was about the same
for the two liquid detergents. 相似文献

在标准洗衣液中添加不同种类和用量的荧光增白剂,根据GB/T 13174-2008进行国标去污力和循环洗涤性能测试。结果表明,若测试光源中包含紫外光,添加荧光增白剂的标准洗衣液的去污力和循环洗涤性能测试结果明显好于标准洗衣液,且荧光增白剂添加量增大,去污值和白度保持值增大;若测试光源中不包含紫外光,两者的去污力和循环洗涤性能测试结果并无明显差异。可见,荧光增白剂没有去污作用和抗污垢再沉积作用,但会显著提高国标去污力和循环洗涤性能的测试值。若要更加合理评价产品去污力,有必要按照GB/T 13174-2008进行洗涤,采用色度仪在不包含紫外光(滤除400 nm以下光源)的光源下测试,或者在含紫外光的正常光源下测试,但使用含有荧光增白剂的标准洗衣液作为参比。同时,GB/T 13174-2008未对白度计型号作出统一规定,使用不同规格的白度计测量添加荧光增白剂的洗涤剂产品时,将有不同的去污力和循环洗涤性能测试结果,建议尽快完善该标准。 相似文献

Algerian montmorillonite treated with sodium chloride was used as a substitute for the builders sodium tripolyphosphate (STPP)
and sodium sulfate in a detergent powder. The following performance parameters of the substituted composition powder were
examined: pH, foaming, cleaning, sequestering, and ion exchange capacities. The latter factors remained the most important
ones for effective detergency. Despite anticipated improvement in hard water ion removal, constant detergency results were
observed with the treated montmorillonite-containing powder. This level of efficacy does not meet the cost-effectiveness of
a standard detergent powder containing STPP. 相似文献

Laboratory and pilot scale investigations were carried out on phosphate-free detergent (PFD) formulations comprising binary anionic surfactants of C16 palm methyl ester sulfonates (C16MES) and linear alkyl benzene sulfonic acid (LABSA) with the aim of maximizing the incorporation of C16MES into low density detergent powders without compromising the detergency and other significant properties. Initial laboratory experiments revealed that the detergent powder resulting from C16MES/LABSA with a 50:50 ratio and pH 7–8 has acceptable detergency stability over 1 week of accelerated ageing test at 50 °C and 85 % relative humidity. Subsequent experiments were carried out in a 5-kg/h-capacity pilot spray dryer using PFD formulations of C16MES/LABSA over the whole range of weight ratios under the same pH of 7–8. The concentration of the detergent slurry and cleaning performance (detergency, foaming ability and wetting power) of the resulting spray dried detergent powder (SDDP) were evaluated. C16MES/LABSA in a 40:60 ratio was selected as the ideal formulation based on its optimum detergent slurry concentration and comparable cleaning performance against the control formulation. Further environmental tests have confirmed that SDDP obtained from the ideal formulation is readily biodegradable (60 % in 13 days) and exhibits low eco-toxicity properties (LC50 of 11.3 mg/L). 相似文献
