It is one of the widely used varieties of water-soluble polymers. Because the polyacrylamide structural unit contains amide groups, it is easy to form hydrogen bonds, so that it has good water solubility and high chemical activity, and it is easy to graft or crosslink a variety of modified products with branched or network structure. It has a wide range of applications in petroleum exploration, water treatment, textile, papermaking, mineral processing, agriculture and other industries, and is known as "Auxiliary Agents for All Industries". The main application areas abroad are water treatment, papermaking, mining, metallurgy, etc.; the current domestic use is in the field of oil production, and the rapid increase in consumption is in the field of water treatment and papermaking
Physical and chemical properties PAM? Polyacrylamide is a water-soluble linear polymer polymerized by acrylamide (AM) monomer initiated by the base. It has good flocculation and can be divided into resistance according to ionic characteristics. There are four types of non-ionic, anionic, cationic and amphoteric type. Polyacrylamide (PAM) is insoluble in most, such as methanol, ethanol, carbon dioxide, aliphatic hydrocarbons and hydrocarbons, except for a few polarities, such as acetic acid, ethanol, ethylene glycol, glycerol, molten urea and urea. However, these have limited solubility and often require heating, otherwise they have little application value. At a suitable low concentration, the polyacrylamide solution can be regarded as a network structure, and the mechanical entanglement and hydrogen bonds between the chains form a network node; when the concentration is high, the solution contains many chain points, which makes the PAM solution It is gelatinous. PAM aqueous solution has good compatibility with many water-soluble organic substances, and has good compatibility with electrolytes, such as calcium sulfate, sodium carbonate, sodium borate, sodium, sodium, sodium sulfate, zinc chloride , Boric acid and etc.
In fluidized bed granulation or pelletizing and coating, the spray should be selected according to the performance of the material and the planned product. The biggest and unique place of this hot air circulation oven is that most of the hot air is circulated in the box. 9. The round bottle automatic labeling machine has high labeling accuracy, no wrinkles, no bubbles, simple, fast switching between different products and labels. Understand that the self-adhesive labeling machine is suitable for flat object care labels in culture, education, food, electronics and other occupations. It is widely used in flat object labeling for large commodities and large-scale flat object care labels. It is also easy to adjust and take. , In addition, the surface of the sealing surface is slippery, and the end surface is notched when the end surface is attached. The sealing element fails. The main reasons are: ①The medium is not clean, and there are tiny hard particles. And fail.
Quick-dissolving is a form of polyacrylamide solids, with a fine powder appearance and the characteristics of a solid flocculant. Quick-dissolving polyacrylamide fine powder has a large molecular weight range, a fast dissolution rate, and low energy consumption. It is easy to store and use. The instant polyacrylamide powder is widely used in the treatment of various industrial wastewater, especially for suspended particles, coarser, high-concentration, positively charged sewage, and the pH of the water is neutral or alkaline. , Iron and steel plant wastewater. Electroplating plant wastewater. metallurgical wastewater, coal washing wastewater and other sewage treatment. Effect. 1 The building industry uses instant polyacrylamide as additives for building mortar, including granules and fine powders. It has strength and will not dry too quickly during construction. Unfavorable phenomena such as napping and peeling. In addition, it is also used to thicken interior wall coatings. 2 It is used as an adhesive for wood boards, diatom boards and other boards. In the dissolution of polyacrylamide, there are many places to pay attention, so in the dissolution of polyacrylamide, it is important to pay attention to these issues. Let's look at the dissolution of polyacrylamide.
