In the fur industry, these surfactants are widely used in the pretreatment and post-treatment of fur processing. Finally, the total use of a surfactant is about% of the surfactant into fur waste water and discharged into the environment. These surfactants have functions together with other organic materials such as emulsification, dissolution, adsorption, making the treatment of dye wastewater more difficult.
Based on the excellent characteristics of the amino acid surfactant, how to make more efficient, more green production and application have become the main development direction: biological enzymes, biological enzymes and chemical synthesis methods more in line with future green development; using natural plants and bio-waste production Economic amino acid surfactants can reduce costs; the study of the relationship between the structural performance of amino acid surfactants will be used to broaden the mainstream development trends of the future amino acid surfactant.
Consumers believe that detergents should be used as a washing product, and should not cause too much damage to the body. When cleaning the tableware, the public will not pay attention to the use of detergents, how much weight, often used, detergents should not be used, market sales Ordinary detergents can only be mechanically fruit and vegetable surfaces, but there is no disinfection, function, such as the amount of surfactant according to detergent residual surfactants, each tray surfactant.
Surface activity is the core of the foam, general concept, former, such as anionic surfactant, cationic surfactant, nonionic surfactant, etc., the latter, such as animal protein, plant protein, pulp waste liquid, etc., foaming agent has high Surface activity, can be effective in liquid surface tension, and arranged in a double electron layer on the surface of the liquid membrane, surrounded by air. Forming bubbles and then consists of a single bubble. Boading and chivalrous, foaming agents have two concepts: generalized and narrow. These two concepts are different.
Since the dose and properties of the defoaming agent are confused due to the use of antifoaming agents, in the case where there is no cylinder, the surface of the fabric is irregularly shaped, the fabric surface is contaminated with an irregular shape. When I first met this phenomenon, I didn't know where a particularly oil came from, so the oil (what color, what color oil) attached to the fabric surface very bright, touch it with hand, then Penetrate into the fabric. The foam ether diffuser makes the foam thin, and an organic polymer such as silicone oil is soaked in a surfactant. The foam ether bubble agent combines alcohol and dirt, which has occurred. Until the foam rupture. Previously, many printing and dyeing enterprises destroy the directional molecules formed by the gas-liquid surface (interface) during operation, and the oil adheres to the fabric. Therefore, while eliminating the foam, there are also many unfavorable factors and negative impacts, or even cause economic losses.
We know that the surface tension of the defoaming agent needs to be lower than the surface tension of the bubble system. The surface tension of the silica gel defoamer is lower than the water, surfactants, aqueous solutions, and most oils, so its defoaming applications are very broad. Features of silica gel defoamers: low surface tension.
Emulsifying oil is a liquid, which is to dissolve and emulsify oil sludge, and nonionic surfactants exert osmosis moist, when oil or fat is dissolved in the fabric, the nonionic surfactant belt detergent, so that solid fouling particles are suspended. Some surfactants (emulsifiers) are added to reduce some hydrophobic materials, various animal and vegetable oils, reduce their surface tension (such as interface tension between oil and water). The small particles are discharged into the water, which is emulsion, which is the emulsification effect.
In short, the machine has been prepared for washing powder at the factory.
Fatty alcohol polyoxyethylene ether AEO series factory Polyoxyl lauryl ether supplier Laureth-2 manufacturer Due to the simple nonionic surfactant without the bleaching ingredient of the washing powder, the washed clothes are not bright enough.
The adsorption process of the surfactant on the surface of the fiber is relatively slow, and it is often difficult to achieve static balance during the cleaning process. In the fully stirred laundry machine, the step of determining the adsorption speed is to spread to the surface of the textile fibers and the surface of the surface. The diffusion speed is related to the size and structure of the surfactant molecule.
Fortunately, many of these surfactants are compatible with each other, so formula designers can combine different types of surfactants to make more effective washing powder. However, compatibility is not the only advantage of using two surfactant systems because the auxiliary surfactant can improve each other's performance during mixing. That is why many recipe designers and chemists typically select the main surfactant and sub-surfactant simultaneously when constructing a mixture, mixture or formulation.
