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:What pigments take part in photosynthesis?
- There are three basic classes of pigments. Chlorophylls are greenish pigments which contain a porphyrin ring. This is a stable ring-shaped molecule around which electrons are free to migrate. Because the electrons move freely, the ring has the potential to gain or lose electrons easily, and thus the potential to provide energized electrons to other molecules. This is the fundamental process by which chlorophyll captures the energy of sunlight. There are several kinds of chlorophyll, the most important being chlorophyll a. This is the molecule which makes photosynthesis possible, by passing its energized electrons on to molecules which will manufacture sugars. All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll a. A second kind of chlorophyll is chlorophyll b, which occurs only in green algae and in the plants. A third form of chlorophyll which is common is (not surprisingly) called chlorophyll c, and is found only in the photosynthetic members of the Chromista as well as the dinoflagellates. The differences between the chlorophylls of these major groups was one of the first clues that they were not as closely related as previously thought.....
- Q:What is the difference between dyes and pigments? Could you give some examples of each one please.
- Dyes are dissolved in whatever solvent is used. Pigments are insoluble. Often a pigment is made by attaching a dye molecule to an insoluble particle. According to my sources a pigment is a coloring matter, usually in the form of an insoluble powder that is mixed with oil, water, etc. to make paint. The pigment lays on the surface and becomes part of the dry film. A dye is soluble in water and is used to color cloth, basket reed and other porous materials. A tube of white toothpaste would be a white pigment for some imaginary use. The same toothpaste, with a red dye added, would be a pink or red pigment. With an overwhelming concentration of dyes, or with black powder added, it could be a black pigment. Silver or metallic colorants can only be pigment.
- Q:do all leaves extract contain the same pigments??why?
- Plants okorder /... Plants have classes of pigments that act as adjuncts to the chloroplast's chlorophyll, in several ways. Some are accessory pigments that broaden the range of absorbed light. These pigments are found in the light gathering arrays in chloroplasts. They also alter the color of the leaf depending on what specific pigments it has to gather light energy and that determines what is reflected (green is the basic reflected spectra but is might be yellowish or bluish green). The major accessory class of pigments, the carotenoids, collect light in the red to yellow wavelengths chlorophyll a can’t, then the carotenoids transfer the energy to chlorophyll a to process. Among the carotenoids are the xanthophylls that provide UV protection for the light gathering centers of the chloroplast. Plants adapt to situations and some just have fewer chloroplasts so have less chlorophyll and absorb less of the light. In low light situations they need fewer so variegated plants are possible. This reduced chlorophyll level allows small amounts of other pigments like the yellow pigment xanthophyll to show up.
- Q:If they are not the same, then what is the difference? Please help me out here.
- Yes, tannins are pigments but they aren't really the main plant pigment. Plant pigments usually refer to photosynthetic pigments (chlorophyll, carotenoids, etc.). These photosynthetic pigments give the leaves their green color (or yellow/orange in the fall). Tannins are non-photosynthetic phytochemical (involved in plant metabolism and internal functioning), but they are also a pigment. Tannins (and lignins) are brown. This is was gives dead leaves and wood their color. Tannins also leach out of the leaves when soaked in water (same process as brewing a cup of tea). So tannins are pigments when they leach out of leaves and stain water (or other things) brown, but they are not photosynthetic plant pigments. In other words, it depends on what context you are calling a tannin a pigment. In a live plant they are not a pigment (judgment call here). In a dead leaf or when they leach out of a leaf they are a pigment.
- Q:I have been looking over the internet and have yet to find the details I need. Such as the function and development of Pigments.
- any of a group of compounds that are intensely coloured and are used to colour other materials.Pigments are insoluble and are applied not as solutions but as finely ground solid particles mixed with a liquid. In general, the same pigments are employed in oil- and water-based paints, printing inks, and plastics. Pigments may be organic (i.e., contain carbon) or inorganic. …
- Q:i love makeup so mucch im like addicted...lol but the only thing is that i only buy that department or drug store brands cause i cannot afford high quality brands. the one that i buy are good for me,,but anyways i was wondering what the heck is mac eyepigment,,what is the diffrence between eyeshow and pigment? pleas help thank u,,,oh yeah and what does it look,like on the eyes?
- a mac pigment is a highly concentrated loose eyeshadow just a little will give u alot of color as opposed to a regular eyeshadow which isn't as vibrant or pigmented to give you a visual, you know when you put on eyeshadow, you have to apply it a few times to see some decent color? .. with mac pigments its so concentrated that in the first stroke you can see the colour as it is in the pot. you can even use it as eyeliner
- Q:what roles do pigments have in energy transfer?
- Pigments okorder /... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.
- Q:how exactly do pigments work? i know that they absorb every color except the one that we see, but what are the exact physics or whatever behind the selective absorption of the light?
- Different pigments mostly absorb different range at different wavelength of light, but plant -as I know- mostly containing chlorophyll does not absorb green light so we see plants as green.
- Q:Why is it important for a plant to have more pigments than just chlorophyll?
- If the plant only has chlorophyll, it is only able to absorb and use the wavelengths of light that correspond to chlorophyll, which is really limiting. Having other pigments allows it to use more wavelengths of light, which is more efficient.
