ASE thickeners rely on a change from low to high pH (neutralisation) to trigger thickening. The “trigger” is built into the copolymer by creating an approximately 50:50 ratio of methacrylic acid, which is soluble in water, and an acrylate ester, which is not soluble in water. When the acid is un-neutralized (low pH
Flocculants are categorized as anionic, nonionic or cationic and therefore affected by pulp pH. Basic thickener operation will have you understand the simple electrics of water. For lack of proper testing, you will need to buy a floc that fits your chemistry or modify it using lime.

The answer is "it depends", what is your standard water pH, what other chemicals are invilved (reagents, flocculents, etc.), what particle size range a are tailings in, and a lot more. Settling rates are based on water and particle surface chemistry, and pH has a role in that.
A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in
17/4/2011 The easiest way to make alkaline water is to thoroughly stir 1/8 tbsp of baking soda into 1 cup (240 mL) of water. You can also buy pH drops, and use them according to the instructions. Read on for more ideas on alkalizing water with additives and filtration systems.
Neutrogena used hexylene glycol as only thickener I see but cant find it anyplace. my ph is 3 as im at %4 SAL . and cant get it thick enough The inactive ingredients are water, sodium C-14-16 olefin sulfonate, cocamidopropyl betaine, linoleamidopropyl PG-dimonium chloride phospatem, hexylene glycol, polyquaternum-22, sodium lauroyl sarcosinate ...
The Ovivo ® sludge thickener is designed to continuously produce as thick a sludge as possible from streams of sludge previously formed and collected in separate settling basins. Included with the thickener mechanism are Ovivo's durable heavy-duty drives. The drive is designed to handle the specified torque for 20 years of continuous operation, but we have seen drives still in operation after ...

thickening effi ciency, and improved color development and stabilization. Its non-ionic character contributes stabiliza-tion over a wide pH range and permits broad formulating latitude. The QP type is of particular interest where controlled hydration is desired, as in the direct addition of the thickener to the water
Thickener optimization to reduce your production costs ... In the thickener process there are many critical key performance indicators that show how the process is running – all of which need to be measured accurately and reliably. ... Orbipac CPF81D pH sensor with CYA 112 mounting assembly.
Dissolve 10g citric acid in about 50g water and add a little at a time while checking with the pH meter (stir gently each time) until the pH is adjusted to 6.0; Add 5g of salt and stir vigorously until the detergent thickens into a white foamy mixture. Set aside overnight for suds to clear out.
Thickening agents are an integral part of SMC and BMC molding technology. ... emulsion polymers are water-insoluble colloidal dispersions that are provided in the form of emulsion polymers at low pH and become soluble or swellable in water and confer thickening when the pH is adjusted above about 6.
ACUSOL™ 823 Rheology Modifier and Stabilizer Description ACUSOL 823 is a Hydrobolically modified, Alkali Soluble acrylic polymer Emulsion (HASE). ACUSOL 823 can be directly incorporated into formulations without necessity for slow preliminary preparation of a separate thickener
The pH of a 0.5 wt % aqueous solution of the water-soluble thickeners of the examples and the comparative examples was adjusted with 10 N sodium hydroxide, and the viscosity of the reagent solution at the various pH levels was measured using a B-type viscometer (12 rpm, 1 min, 25° C.) and these were compared.
Typical components of a hard surface cleaner, in addition to the copolymer thickener and surfactant mentioned previously, include sufficient base to attain a pH of 10-13, and optional ingredients, including 0.25-5% electrolyte, 1-10% glycol, and 0.5-5% silicate salts, e.g.,
The greater the ratio of xanthan gum added to a liquid, the thicker the liquid will become. An emulsion can be formed with as little as 0.1% (by weight). Increasing the amount of gum gives a thicker, more stable emulsion up to 1% xanthan gum. A teaspoon of xanthan gum weighs about 2.5 grams and brings one cup (250 ml) of water to a 1% ...
The combination of aeration, high pH, and mixing causes the iron, manganese, and other heavy metals (if present) to precipitate to the fullest extent possible at the set pH level. Thickening/Clarification. Treated water flows to a thickener for sludge thickening and clarification of the water.
The cellulose ether can be used as the water-retaining agent. The water retention effects of cellulose ether can prevent the substrate from absorbing moisture too much and too fast, and can prevent the evaporation of water, in order to ensure sufficient water during hydration of cement. Generally speaking, the water
