1、高效氟蛋白泡沫灭火剂

      向蛋白泡沫液中加入OBS－异丙醇－水溶液（比例约为4:3:3）制成高效氟蛋白泡沫灭火剂（含OBS约0.015W%）,同时可选用烷基苯磺酸钠、烷基萘磺酸钠、脂肪醇硫酸钠等碳氢表面活性剂与之互配。由于氟表面活性剂优异的表面性能，能够迅速形成稳定的泡沫在油面上铺展开来，灭火速度是普通蛋白灭火剂的3～4倍。适用于油库、油罐等液下喷射型灭火装置（并可用于普通蛋白泡沫消防设备），100M3油罐灭火试验表明，当灭火剂供应强度控制在9～10立升/m2·分时，油罐灭火时间低于3分钟。OBS还可与干粉灭火剂联用，灭火效果良好，非常适合扑灭由油类形成的火灾，成为油田、油库、交通运输部门燃料库（如加油站），化工厂等安全生产所必备。另外，在普通抗溶泡沫灭火剂添加OBS后，制得氟蛋白抗溶泡沫灭火剂，能够显著提高泡沫的耐液性和耐热性，非常适合扑灭醇类和酮类等水溶性液体的火灾。

2、石油开采

      OBS在石油开采中用于二次、三次采油，是生产采油助排剂的一种主要原料，可以降低压裂液的表面张力或油水界面张力，具有溶蜡降粘、高效发泡助排等优点。OBS因为具有更高的表面活性，可以显著降低原油与驱油体系间的油水界面张力，使原油从岩层和油砂上脱离出来，与采油助排体系一起被水压到地面，提高采油的效率和产量。并且OBS与普通碳氢表面活性剂能够很好的复配使用，能够起到减低成本和提高效益的作用。一般用量为0.3%左右。

3、钢板清洗

      在对钢板作清洗用的水基型清洗剂中加入适量的OBS，就能明显的增强去污能力，提高实际工作效率，同时不易被残留的水份腐蚀生锈。

4、感光胶片

      作为抗静电剂混溶于相关溶液内涂在胶片的片基上，解决了胶片生产过程中因片基的高速转动摩擦而产生的静电火花的可能，保证了胶片生产过程中的产品质量。同时可显著增强其它成分在片基上的分散速度和分散效果。使用OBS可以在感光胶片中减少有害杂质，使感光胶乳流平剂用量降低到原用量的1/40，流平效果更佳。

5、印刷

      普通油墨在塑料薄膜和表面经过处理的光滑纸张上进行印刷和书写时往往碰到缺色、断线、难上色彩或油墨附着性差，涂液出现鱼鳞状现象，在其中添加适量的OBS（一般为0.01%-0.1%）后,能显著提高油墨的流平性、辅展性和润滑性，并降低了油墨的表面张力，提高了它的粘附性，帮助其形成良好的涂膜层，并可消除油墨的严重粘辊现象，改进颜料润湿性等。如OBS加入GG透明黄颜料（用量约0.067W％），显著改善了颜料对油类的润湿性能，并使颜料粒子变软，大大提高了轧墨作业性能，解决了使用TX-10乳化剂时无法解决的咬辊问题。

 6、其它用途

造纸：在石腊—松香—水体系中添加OBS含氟表面活性剂，可以方便地制得质量高，稳定性好的石腊—松香—水分散液。

电镀：保持被涂制件表面清净是取得高质量电镀层的先决条件，特别是铜制品的无氰电镀。在被镀制品的洗涤液中加入约0.3%的OBS，可获得满意的洗涤效果，能够显著减少铬雾挥发。

浸渍、涂层：在聚四氟乙烯或氟塑料FEP（F46）的浓缩分散液中加入OBS（作为分散剂），可使分散液获得更好的湿润性能，从而制得各种满意的浸渍玻璃纤维制品和光洁的金属表面涂层。

      Sodium flunonenoxybenzenesulfonate (OBS) has low surface tension and critical micelle concentration, good chemical resistance, and can still maintain good surface activity in strong acids and bases. It is an anionic fluorinated surfactant, according to its high cost performance, high surface activity, excellent water and oil repellent properties and other characteristics, widely used in detergents, latex, coatings, pigment additives, emulsifiers, dispersants, wetting agents, fluorine protein fire extinguishing agents, oil displacing agents, oil concentration agents, foaming agents, antistatic agents, lubrication additives, chromium fog inhibitors, metal, plastic etching additives Agent, leveling agent, release agent, paper oil repellent treatment agent and other fields, in order to improve the production process conditions, improve product quality grade, increase output, reduce consumption, save energy, improve the production environment, improve production efficiency.

1、 high efficiency smoked protein foam fire extinguishing agent

      Add OBS-isopropyl alcohol-aqueous solution to the protein foam solution (the ratio is about 4:3:3) to make high efficiency fluorine protein foam ), at the same time can choose alkyl benzene sulfonate, alkyl caisulfonate sodium, sodium fatty alcohol sulfate and other hydrocarbon surfactants with the surface properties of each other, can quickly form a stable foam spread out on the oil surface, fire speed is common protein fire extinguishing agent tank and other liquid spray type fire extinguishing device (and can be used for common protein foam fire fighting equipment), 100M3 tank fire test table in 9-10 vertical liters /m2· time, tank fire time is less than 3 minutes. OBS can also be combined with dry powder fire agent, fire extinguishing effect formed, become oil fields, oil depots, transportation department fuel depots (such as gas stations), chemical plants and other safety production foam fire extinguishing agent after adding OBS, the preparation of fluorine protein anti-soluble foam fire extinguishing agent, which can significantly improve the liquid resistance of foam and water soluble liquid fire resistance such as ketone.

2. Oil exploitation

      OBS is used secondary in oil extraction. Tertiary oil recovery, is a main raw material for production of oil extraction aid, can be oil-water interfacial tension, has the advantages of wax dissolution viscosity reduction, high efficiency foaming aid drainage. OBS has a higher oil-water interfacial tension between the surface active system, so that the crude oil is separated from the rock formation and oil sand, and the oil production and drainage aid system together with the water pressure to the volume, and OBS and ordinary hydrocarbon surfactants can be well mixed and used, can reduce the cost and improve the efficiency.

 3、steel plate cleaning

      Adding an appropriate amount of OBS to the water-based cleaning agent used for cleaning the steel plate can significantly enhance the decontamination ability, and it is easy to be corroded and rusted by residual moisture.

4.photosensitive film

      As an antistatic agent, it is mixed in some solution and coated on the film base, which solves the possibility of the film base spark in the film production process and ensures the product quality in the film production process. At the same time, it can significantly enhance other components on the film base with OBS can reduce harmful impurities in the photographic film, so that the amount of photographic latex leveling agent reduced to 1/40 of the original amount, leveling.

5.printing

      Ordinary ink in plastic film and surface treated smooth paper for printing and writing often encounter a lack of color, poor performance, the coating liquid appears fish scale phenomenon, in which to add the appropriate amount of OBS (generally 0.01%-0.1%), can be significant; And lubricity, and reduce the surface tension of the ink, improve its adhesion, help it form a good coating layer, such as, improve the pigment wettability. For example, OBS adds GG transparent yellow pigment (the amount is about 0.067W%), significantly improves the soft pigment particles, greatly improves the performance of ink rolling, and solves the bite roller question that cannot be solved when using TX-10 emulsifier.

6.Other uses

Paper making: Adding OBS fluorine-containing surfactant to the shite wax - rosin monohydrate system can be used.

The high quality and good stability of the ground preparation of paraffin-rosin-water dispersion.

Electroplating: Keeping the surface of the coated part clean is a prerequisite for obtaining high-quality electroplating, especially cyanide-free electroplating of copper products. Adding about 0.3% OBS to the washing solution of plated products can obtain satisfactory washing effect, which can significantly reduce the volatilization of chromium fog.

Impregnation,coating:In the concentrated dispersion of polytetrafluoroethylene or fluorine plastic FEP (F46) into OBS (as a dispersant), can make the dispersion of better wetting performance,so as to make a variety of satisfactory impregnated glass fiber products and smooth metal surface coating.
