Wax Emulsions with Power Ultrasonics When wax is dispersed as nano droplets with a very homogeneous distribution, a stable wax emulsions is obtained. Ultrasonic homogenizers generate high shear forces and are reliable and robust systems to produce stable wax nano-emulsions.   Cracking of emulsion can be due to: 1-addition of an incompatible emulsifying agent: e.g. monovalentsoap + divalent soap 2-chemical or microbial decomposition of emulsifying agent: e.g. alkali soap decompose by acid. 3-exposure to increased or reduced temperature 4-addition of common solvent.

Jacquard Acid Dyes will dye yarn or fibers and fleeces, silk, wool fibers, cashmere, alpaca, feathers, and most nylons easily and are also great for overdying. Don't be alarmed by the name Jacquard Acid Dye, the only acid involved is the vinegar that you add yourself.   General Information & Use for Dharma Acid Dyes Applicable to any brand of Acid Dyes. Acid Dyes are the dye of choice for dyeing all protein fibers, like wool and other animal hair like alpaca, angora, mohair, etc., silk, feathers, and also they dye nylon. They are even used on leather sometimes/5().

  Fiber Reactive vs Acid Dyes. Posted on July 3, by ruthlane. I have always used acid dyes for wool and silk because the results are good, the colors are strong and the dye is fairly light and wash fast. Since I need to use fiber reactive dyes for my stitch class, I decided to see if fiber reactive dyes (Procion MX) would work on wool. Emulsions and Emulsion Stability, Second Edition provides comprehensive coverage of both theoretical and practical aspects of emulsions. The book presents fundamental concepts and processes in emulsified systems, such as flocculation, coalescence, stability, precipitation, deposition, and the evolution of droplet size distribution.

Technical wax dispersions have many different uses and accordingly vary considerably in their chemical composition. Ionicity, solids content, wax type and dispersion type (W/O or O/W) are variable and largely depend on the type of emulsifier used.

For these different applications Clariant offers beside montan based waxes a range of oxidized Polyolefin waxes. 3) Micellar emulsions or microemulsions: these usually have the size range of 5–50nm. They are thermodynamically stable.

4) Double and multiple emulsions: these are emulsions-of-emulsions, W/O/W, and O/W/O systems. 5) Mixed emulsions: these are systems consisting of two different disperse droplets that do not mix in a continuous Size: KB.

A wax emulsion is a stable mixture of one or more waxes in and water are normally immiscible but can be brought together stably by the use of surfactants and a clever preparation process. Strictly speaking a wax emulsion should be called a wax dispersion since the wax is.

CHAPTER 11 EMULSION BREAKING An emulsion is an intimate mixture of two liquid phases, such as oil and water, in which the liquids are mutually insoluble and where either phase may be dis-persed in the other.

In water chemistry, two types of emulsions are commonly found, oily wastewater (oil emulsified in water or O/W emulsions) and waste oilFile Size: 1MB. bees wax was taken in mL conical emulsions show less weight loss and flask and melted it at 70 oC, heated better water resistance.

g File Size: 73KB. Wax Emulsion Solutions. Hexion is one of the largest producers of conventional and specialty wax emulsions, serving many industries. Our emulsions have earned a reputation for superior performance, stability (even in long-term storage), consistency, applied cost and technical support.

Wax Emulsions. ADDAPT WaxMul. The WaxMul products are based on different waxes like carnauba, paraffin & polyethylene wax. The applications depend on the wax type used; carnauba based wax emulsions are excellent release aids, lubricants and scratch resistance additives, whereas paraffin and polyethylene wax emulsions are used for surface effects and water repellency.

Carnauba wax is a wax of the leaves of the palm Copernicia prunifera, a plant native to and grown only in the northeastern Brazilian states of Piauí, Ceará, and Rio Grande do Norte.

It usually comes in the form of hard yellow-brown flakes. It is obtained from the leaves of the carnauba palm by collecting Continue reading Carnauba Wax →.

When an emulsion separates into its separate ingredients (when the oil and. water are clearly separated and will not recombine) the emulsion is said to have "cracked" or "broken." Do not confuse a "cracked" emulsion with one that has creamed. Creaming is a natural occurrence with most emulsions and simple shaking will.

Waxes & Emulsions. The H&R Group is focused on waxes. Based on our integrated raw material portfolio, we develop, produce and sell waxes and formulated waxes for specific industrial applications.

The subject matter of the present invention is a method for the production of emulsifier utilizing wool wax alcohols obtained by high-pressure hydrogenation, wherein the starting materials are (1) wool wax acids in the presence or absence of monovalent aliphatic alcohols having 1 to 6 carbon atoms, or (2) wool wax acid esters of lower alcohols.

Wax emulsions provide the smallest particle size. The average wax particle size in an emulsion is often less than one micron. The fine particle size can result in a lack of efficiency as a coating additive.

It gives improve water repellency. IMPERMAX ® LS 51 contains 50 % of dry matter and is an anionic acid stable emulsion. # Impermax® T Orcolan Fast™ dyes for wool represent a group of acid metalized chrome-complex dyes with excellent leveling properties in strongly acid conditions such as carbonized wool.

Although this line is somewhat limited in shade range it is very popular due to its ease of application and good fastness properties and finds wide use in stock dyeing especially in those areas destined for cross dyes.
