3. Application

(1)Displacement agent for tertiary recovery of oilfield.

It can adjust the rheology of water injection,increase the viscosity of fisplacing liquid,improve the spreading efficiency of liquid displacement ,bring down the water permeability in strata and keep water and oil to flow at a constant speed.it is mainly used in tertiary recovery of oilfields.injection of each ton of PAM products can help to gather 100-150 tons extra crude oil.

(2)Drilling mud material.

 Used as drilling mud additives in oilfield exploration and development and geology,water conservacy and coal exploration.i can prolong the bit’s life,raise the drilling rate and drilling footage,reduce the time of exchange drills.it has abvious effect in avoiding well collapse.it can also be used as oilfield fracturing fluid and profiling water blocking agent.

(3) Industrial wastewater treatment.

 Especially for the treatment of wastewater containing suspendent particles which is coarse,high concentration and with positive charges and water’s PH value is neutral or alkaline.most effective for wastewater treatment of iron and steel plant,electroplate factory,metallurgy and coal washing.

(4)Drinking water treatment.

Many water plants in China come from river water,which contains large sum of sediment and mineral,very turbid.after precipitation and filtration,it still can not meet the requirements.flocculant is needed.water plants used to use inorganic flocculants.but large additive amount is required which caused the increase of sludge volume,not effective.use anionic PAM flocculants,with 1/50 additive amount that of inorganic flocculants,several times and even dozens of times effectiveness obtained than that of inorganic flocculants.for those organic polluted river water,better effectiveness can be achieved while mixed used together with cationic PAM.

(5)Papermaking additives.

Can be used for caustic soda’s clarification.used as retention aid,filter aid,reinforcing agent for wet and dry paper.

(6)Clarifying agent in sugar refining industry.

(7)Additives and adhesives in aquatic product feedstuff.

4. Instruction for use

(1)It's very important to make the efficient dispersion during using, otherwise will cause agglomerate and "fish eyes", dissolving time will be longer.

(2)Low-hardness water for use; avoid adopting such tank or pool, which will influence on water quality.

(3)Improve the water temperature to accelerate the dissolving velocity, but not exceed 50.

(4)Stirring will accelerate dissolving, but tough stirring will make the dispersant chain broken and degradation. Shipshape agitator with 200 - 500 rpm is the best choice.

(5)Commonly mix the product into 0.05%--0.5%(w/w)solution as reserve.

(6)Adjust the optimum dosage of product according to application condition.

Q:why do plants need more than one pigment for light absorption?
Pigments are molecules with an array of covalent bonds capable of absorbing a photon of light that has only a certain wavelength. The absorbed wavelength is only a fraction of the continuous range of wavelengths reaching the reaction center of a chloroplast. Each pigment species absorbs a different portion of the spectrum. So most photosynthesis works in combinations of pigments to absorb a across the visible spectrum and somewhat beyond. Some pigments (accessory photosynthesis carotenoid pigments) absorb useful wavelengths to pass the energy to chlorophyll A while the Xanthophyll Cycle pigments absorb potentially harmful high energy wavelengths for dissipation. Accessory pigments provide a range of spectra collection that allowed plants to adapt successfully to environments of differing light conditions. Pigments provide coloration to signal flower or fruit maturity to pollination partners or seed dispersal partners. Anthocyanins and carotenoids perform these communication functions. Phytochrome is a pigment that absorbs one wavelength only to toggle to another shape capable of absorbing at a different wavelength. Algae and plants both use this system to inform them of the time of year so they can synchronize with the best season in their habitat for reproduction efforts to succeed. Plants use phytochrome to regulate the photoperiod of flowering or seed germination.
Q:i bought mac pro pigments 4 the 1st time , now what do i do?
For MAC pigments you need a thick natural base underneath them to make them hold, and shine amazingly... I use paint pot base. Use a stiff eye brush and dab it in the pigment container. before applying it on your eye, shake off the access of it. make sure you have a base underneath though!
Q:Oil paint: what's the pigment, binder, and vehicle?
Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
Q:what is pigment eyeshadow?
All these people are looking for a way through which they can make their skin look good. Yet, what they have not taken into consideration is the power of natural ingredients. Fruits, vegetables and products coming from animals are great sources of anti-oxidants and are rich in substances which can whiten the skin, moisturize it, attenuate the fine lines and wrinkles and give it elasticity.
Q:What is a pigment?????????!?
a pigment is a naturally produced substance in humans and nature in general, that reflects light that is perceived by our eyes as colour -a person without pigment would show totally white hair, and pale pink skin and eyes (the pink is from the blood vessels) -we have it to protect us from the sun --> naturally dark or tanned people have lots, rarely get burned or skin cancer; fair-skinned people were designed for the northern areas with less sunlight, burn easily
Q:what is a pigment? Please describe it, and tell me the uses.?
Pigments are a natural color in organisms. To understand pigments, you must understand the reflections of light. Pigments allows for organisms to have color, like the blue or brown in the eyes. For example, leaves in plants are color green because their pigments absorb all the colors because of photosynthesis except green and reflects off the color. Their plants are usually not green because they don't need to absorb light as much as the leaves does. Pigments depend on the type of light it absorbs. You are green in a dark room with green light right?
Q:how exactly do pigments in a plant work?
How Pigments Work
Q:Separation of plant pigments?
Separation of plant pigments using chromatography. Paper chromatography is a useful technique in the separation and identification of different plant pigments. In this technique, the mixture containing the pigments to be separated is first applied as a spot or a line to the paper about 1.5 cm from the bottom edge of the paper. The paper is then placed in a container with the tip of the paper touching the solvent. Solvent is absorbed by the chromatographic paper and moved up the paper by capillary action. As the solvent crosses the area containing plant pigment extract, the pigments dissolve in and move with the solvent. The solvent carries the dissolved pigments as it moves up the paper. The pigments are carried along at different rates because they are not equally soluble. Therefore, the less soluble pigments will move slower up the paper than the more soluble pigments. This is known as developing a chromatogram.
Q:thinking about the main role of pigments in photosynthesis...?
Green pigments absorb light in the red and blue parts of the spectrum and reflect the green back to our eyes. The major functional difference between chlorophyll and say jade green is that only the chlorophyll in living systems can transfer the absorbed light energy and the excited electron to another molecule, thus trapping it. In biology, pigment is any material resulting in color in plant or animal cells which is the result of selective absorption. Some biological material has so-called structural color, which is the result of selective reflection or iridescence, usually done with multilayer structures. Unlike structural color, pigment color is the same for all viewing angles. Nearly all types of cells, such as skin, eyes, fur and hair contain pigment. Butterfly wings typically contain structural color, although many of them contain pigment as well. Creatures that have deficient pigmentation are called albinos. In the coloring of paint, ink, plastic, fabric and other material, a pigment is a dry colorant, usually an insoluble powder. There are both natural and synthetic pigments, both organic and inorganic ones. Pigments work by selectively absorbing some parts of the visible spectrum (see light) whilst reflecting others. A distinction is usually made between a pigment, which is insoluble, and a dye, which is either a liquid, or is soluble. There is no well-defined dividing line between pigments and dyes, however, and some coloring agents are used as both pigments and dyes. In some cases, a pigment will be made by precipitating a soluble dye with a metallic salt. The resulting pigment is called a lake.
Q:What is the difference between a pigmented eyeshadow and a non - pigmented one?
Pigment is the amount of saturated color that will come up when you touch the eye-shadow with your finger (or apply it with a brush) A poorly pigmented dark purple eye shadow may leave only a soft wash of sheer lavender pigment on the eye, and it may require you to apply several layers to achieve a color similar to how the shadow looks in the pan. A highly pigmented shadow has great color payoff, and looks (on the eyes) the same as it does in the pan, and doesn't require lots of packing on the color. Highly pigmented eye shadows are preferred by most people because they are quicker, and easier to work with and stand out. Poorly pigmented eye shadows, however, may be great for younger girls who are just starting to wear makeup, girls with very fair skin, or people who like Subtle makeup An example of poorly pigmented eye-shadow would be the Color Workshop palettes often sold at drugstores around Christmas, they are fine for beginners, but for people who want dramatic makeup they will not be able to achieve the look with shadows of this quality. Wet n wild 3 pan palettes, and most of the 8 pan palettes are very pigmented, as are L'Oreal infallable eyeshadow-pots, MAC eyeshadows, urban decay eye-shadows and most of the higher end shadow brands. Some eye-shadows targeted towards older women, such as Elizabeth Arden, although pricey, lack pigmentation.
