PHPA hydrolyzed polyacrylamide

Application Field:

1) EOR fields: The types and capability of macromolecule and super-macromolecule adopted in the third oil extraction (EOR) of the oilfield:

2) Flocculant: used widely for waste water treatment; industry sewage treatment, especially the sewage with high density, bit suspending granules, such as, the sewage of steel factory, electroplating factory, it has advantages of low cost and no pollution, also can be used in paper-making etc.

3) Drilling mud chemicals: in oil field exploration and development and exploration of geology, water and coal, it is used as adhesive of well drilling mud raw materials, can improve the service life of drill bits, improve the drill speed and drilling footage, and reduce plug in replacing drill, and has prominent well slough preventing effect, and it can be used as fracturing fluid of oil fields or plugging agent of controlling profile and plugging water.

3) Paper-making industry: can be used as fining agent, residency agent, filtration aid and paper dry and wet intensity reinforcing agent in paper-making industry.

4)Slsughter, House and Dairy waster waster treatment, Private soil modification.

PHPA hydrolyzed polyacrylamide powder

Package and Storage:

1. The solid product can be packed in inner plastic bags, and further in polypropylene woven bags with each bag containing 25Kg.

2. This product is hygroscopic, so it is should be sealed and stored in a dry and cool place below 35°C.

3. The solid product should be prevented from scattering on the ground because the hygroscopic powder can cause slipperiness.

Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down: Whether the chemical reaction can be carried out according to the change of free energy, but only according to the change of free energy can not determine whether the reaction can be completed, because the chemical reaction is also completed by the reaction of the energy barrier, that is, if the reaction energy barrier is high, To provide some energy, across the barrier, to complete the reaction. The energy barrier is called activation energy. And the role of the catalyst is to reduce the activation energy, so that in a relatively harsh environment, chemical reaction occurs.

Q: what is the role of a catalyst in a chemical reaction?: A catalyst is used to speed up a chemical reaction. It is not consumed during the reaction.

Q: describe a biological catalyst?: Biological catalysts work in similar fashion to inorganic catalysts. The lower the activation energy (Delt. G) of the rate limiting step in an SN1 or SN2 reaction. However, they are comprised of biomolecules susceptible to degradation and are quite sensitive to temperature change.

Q: What happens to a catalyst after a chemical reaction?: If it is only a catalyst, then by definition it will still be there at the end.

Q: What are the requirements for the catalyst for the chemical industry?: Generally find a few, according to the cost and cost of cost, choose cost-effective

Q: Comparison of biocatalysts with chemical catalysts!: (1) The chemical reaction catalyzed by the biological enzyme is generally carried out under relatively mild conditions. (2) The enzyme has the highest activity at the optimum temperature and pH, and the temperature of the biocatalyst is more moderate. And PH high or low, the enzyme activity will be significantly reduced.In general, the animal in the enzyme the optimal temperature between 35 ~ 40 ℃; plant enzyme in the optimal temperature between 40 ~ 50 ℃; animal body Of the enzyme most of the most suitable pH between 6.8.0, but there are exceptions, such as the optimal pH of pepsin 1.5; plant enzymes in the most suitable pH between 4.6.5. (3) acid, Or the temperature is too high, the enzyme structure will be destroyed, so that the enzyme permanently inactivated .0 ℃ or so, the enzyme activity is very low, but the spatial structure of the enzyme is stable, at the appropriate temperature of the enzyme activity can be increased The

Q: What is the reaction of hydrogen peroxide to add manganese dioxide?: Hydrogen peroxide → water + oxygen (arrows on the manganese dioxide, as a catalyst)

Q: Brief introduction of enzyme as biocatalyst and general chemical catalyst and its personality: enzyme inactivation (4) enzyme activity can be timely and effective regulation (5) the role of the enzyme conditions are more moderate (6) most of the enzyme (1) the catalytic efficiency is very high (2) Of the catalytic activity is often associated with coenzymes, auxiliary or metal ions, and some enzyme activity also need RNA as a cofactor Caixing, such as telomerase

Q: Hydrogen and nitrogen in the high temperature and pressure and catalyst conditions for the synthesis of ammonia chemical equation: 3H2 + N2 = 2NH3 conditional catalyst

Q: Chemistry: Does the catalyst participate in the reaction?: The catalyst does not participate in the reaction, except that the reaction rate is changed.
