Terms of reference
For the search of producers of anionic surfactants and their mixtures with nonionic surfactants,for elaboration of foaming agent with multi expansion stable foam.
1.Description.
Fire extinguishing foaming agents also known as foam concentrates are concentrated solutions of surfactants.For preparing foam forming solution the initial foam concentrate (foaming agent) is 94-99% diluted with water so that quantity of foaming agent in working mixture tots up to 6% and less.
Capability of forming only low expansion foam or multi expansion one (forming of low,medium and high expansion foam all at once,according to foam generator construction) depends on surfactant molecule structure.
Foaming agents are multicomponent water solutions that consist of one or few kinds of surfactants,additives that provides thermal and hydrostatic stability of foam and its low freezing temperature,corrosion inhibitors and agents that provide compatibility of above mentioned components.
For getting low,medium and high expansion foam with foam generators are used foaming agents on hydrocarbon surfactant basis.These agents provide high foaming capability of water solution.
2.Task.
Choosing of concentrated water solution of anionic surfactant agents on hydrocarbon basis for getting stable low,medium and high expansion foam on GPS 100 (6 atm.) apparatus.
3.Objectives.
3.1 Getting of foaming agent water solution with foam expansion rate not less then 70,stability rate from 1200 and higher on the basis of samples of sodium and triethylamine (possibly triethanolamine) salts of fatty alcohol alkyl sulfate with the length of alkyl C8/10 and C12/C14 from producer (-s)
3.2 Search of sodium (triethylamine,triethanolamine) salts of fatty alcohol alkyl sulfates:
- sodium C12/14 alkyl sulfate
- sodium C8/C10 alkyl sulfate
主要是将Objectives那部分翻译得比较详细就可以了.
英语我都是看得懂的,主要是想把专业的术语翻成通俗的词语.
不过请用机器翻译的朋友不要再提交上来了,
这么大片文章这样让别人翻译可能性不大哦!我用google(http://www.google.cn/language_tools?hl=zh-CN)拿来翻的,尽管错误很多,但是至少可以让你看懂个大概~顺便推荐下google的翻译,算是机器翻译里我所见到过最不错的了~
职权范围
