植物气味控制技术之: 植物中和剂 Botanical Odor control technologies: Botanical Neutralizers
美国新概念的植物气味中和剂与市场上的其它中和剂是完全的不同的配方，并显然的不同于气味“遮蔽剂”。我们使用的成份都是纯的具有与气味分子进行中和能力的植物提取液，纯食物级有机化学物，和植物衍生物。NWC’s botanical Odor Neutralizers are different from nearly all other neutralizers on the market, and are clearly different from odor masking agents. NWC uses a variety of odor control plant extracts based largely on unique blends of food grade organic chemical compounds and botanical derivatives.
所有美国新概念的植物气味中和剂能对付广泛的气味源，我们的产品设计可以攻击酸性碱性或中性的气味物质。这些产品通过与气味化学物发生中和化学反应来把它们转化为非气味性的不溶解性的盐，或者与它们离子化地结合，使它们从水介质中沉降“洗出”。这些化学反应能发生在广泛的空气温度条件，使得在极大部分的现场条件都能产生良好的气味控制的效果。许多竞争的产品主要是依赖精油的香气，所以远不如我们的产品所能适应的广泛的应用。请看下面产品举例: All of NWC’s Botanical Odor Neutralizers work well against a broad consortium of odors。 Our products have been formulated to target malodors that are alkaline,acidic, or neutral in nature. These materials work by either chemically-reacting with the odor causing chemicals, turning them into non-odorous insoluble salts, and/or ionically binding to them, allowing them to “wet-out” in the aqueous phase of the system and precipitate into the air. These chemical interactions occur across a wide variety of ambient temperatures, yielding outstanding odor control performance under all field conditions. Many competitive products that rely primarily on blends of essential oil fragrances are by far not as effective across such a wide spectrum of applications. Please take a look following example of products:
• 气味中尉: 是专门设计用来对付碱性气味物质，如闻起来象粪臭的气味，氨气，丁胺，和其它有毒胺类，或常在鱼和牛奶场废水中存在的中性气味物质。消除它们的毒性和气味替力。例如，这些有毒的胺与产品中的 “两性”有机酸反应，下面是产品分别与氨气和硫醚的化学反应式例子
NH3 (氨气-碱性物质) + Odor Lt.(气味中尉) = CH3COONH4 (胺盐) or RCH2CONH4
GH3SCH3 (硫醚类，中性物质) + Odor Lt.(气味中尉) = 吸附性物质(非挥发性)
Odor Lieutenant: is especially effective against alkaline compounds such smells as Skatole (the odour of faeces), Ammonia, Butylamine and other noxious Amines) or neutral compounds often found in fish and dairy waste with their toxic and offensive potential. For example, these noxious Amines react with the amphoteric and organic acids in the product as shown in this equation.
NH3 (ammonia-alkaline) + Odor Lt. = CH3COONH4 (amine salt) or RCH2CONH4
GH3SCH3 (neutral compounds) + Odor Lt. = ADSORPTION PRODUCT (NON VOLATILE)
• 气味下士: 主要由从不同的植物中提取的“两性”表面活性剂，有机食物级酸性物质，胺(单乙醇胺)和有机盐等组成。它的主要功击目标是强的酸性气味如硫化氢，甲硫醇等与脂肪酸和污水相关的气味，做为NWC植物气味中和剂步兵兵团的成员之一，气味下士也包括一些乳化剂帮助油的分解，减少脂肪在设备中的的堆集，减少设备的维护费用并增加使用寿命。它与硫化氢中和的原理可用下面反应式表达:
H2S(硫化氢) + Odor Corporal(气味下士) = RNH3SH (二硫胺盐)
Odor Corporal: is composed of a specially built amphoteric surface-active agent, organic food acid, Amine(Monoethanolamine) and an organic salt that extracted from different plants. It attacks strong acid odors like hydrogen sulfide, methyl mercaptans, and other gases associated with sewage and fatty wastes. As one of NWC’s Botanical Odor Neutralizing Infantry Combatants, Odor Corporal also has various emulsifying agents which help with the dispersion of oil and reduces fat build up on machinery, reducing maintenance costs and prolongs equipment life. It is designed to neutralize hydrogen sulfides using the following reaction:
H2S (hydrogen sulfide) + Odor Corporal = RNH3SH (amine-bisulphide salt)
• 气味中士: 是美国新概念的顶级植物气味中和剂。不象传统的气味控制产品是基于精油的香气，它会挥发的很快，而气味中士是以100%的固体浓度供应，就是与水混和后，所提供的气味控制效果也能持续几天而不用重新施药。气味中士,包含有若干特殊的天然植物提取物和其它的有机食物级化学物质，可以抑制硫化氢气。因为它能用它产生对硫还原细菌的毒性来解开打断硫还原细菌新陈代谢过程中的电子转移链。当这个新陈代谢路径被破坏，硫还原细菌就没法把硫化物还原成硫化氢气体。
Odor Sergeant: is one of NWC’s top bonatical neutralizers . Unlike conventional odor control products based on essential oil fragrances that volatilize fairly quickly, Odor Sergeant is supplied as an almost 100% solid concentrate that, even after dilution with water, provides effective odor control performance for several days without having to be reapplied or re-misted. Product, Odor Sergeant, contain special blends of a naturally occurring botanical extracts and other food grade organic chemicals that can sequester or suppress hydrogen sulfide gas. Odor Master Sergeant works on H2S gas by uncoupling the electron transfer process in the sulfate-reducing bacteria (SRB) that are producing this toxic chemical. When this metabolic pathway is blocked, the SRB are incapable of reducing sulfate to H2S.
为什么不宜使用“遮蔽剂”Why not to use: masking agents
气味遮蔽只是用一种气味代替另一种气味。一个普通的例子是用一种水果味来遮蔽现有的嗅气。气味遮蔽的效果往往是气味的混合，最终香气与嗅气的混合不一定是一种好闻的气味。 气味遮蔽不是化学地中止气味源，而是准许嗅气的存在。有些有害的气味源，如硫化氢和氨气，如用另一种香气把它遮住后，使有害气体仍存在于环境中，而使您感觉不到，这对人造成的危害会更大。 我们强烈地建议我们的顾客，不要依赖于气味遮蔽剂。而我们愿用我们的优良服务为您提供一个完善彻底的解决您的气味问题的方案。Odor masking merely substitutes one odor for another. A common example of this is placing a fruity odor over an existing bad odor that might be coming from the waste. Odor masks typically “mix” odors but the net result may be a combined fragrance that is not at all pleasant to smell. Odor masks do not chemically “stop” the odor at its source, but rather allow it to persist. Some odors are especially toxic (hydrogen sulfide, ammonia). Masking such malodors with a nice fragrance does not minimize the exposure of personnel to the health hazards of these chemicals, and can result in a potentially dangerous situation. So, we strongly advise all of our customers not to rely on masking agents, but rather work with their NWC sales representative in determining which of our Odor Battalion combatants will work best for your particular situation.
