Kasen as water treatment material exports of key enterprises, more than thirty years of steady development, advanced production and testing equipment, sample tests, customized production, and provide a one-stop the whole process of water treatment services, 华泉荣 was 2012 degrees Environmental Protection Advanced Honor, China Springs - rest assured your choice! For a long time, as an efficient flocculant, PAC has been widely used in the treatment process. In recent years, PAC is also increasingly used in the paper industry. Early eighties, Europe pioneered the development of dispersed rosin (DRS) / PAC (PAC) neutral sizing system, instead of using the PAC * Aluminum successfully achieved the rosin neutral sizing. Meanwhile, the PAC in the wet end of the paper can play a good retention, filter effect. The basic concept of PAC PAC (Polyaluminium Chloride), referred to as the PAC, also commonly known as basic aluminum chloride, poly hydroxy aluminum, aluminum chloride and aluminum hydroxide between two substances it is between a water-soluble inorganic polymer, typically represented by the formula Aln (OH) mCl3n-m represented, where n represents the degree of polymerization, depending on the various factors in the manufacturing process, m represents a certain PAC Neutral degree of the product, namely the number of hydroxide ions replace the extent of chloride ions. Thus, a particular kind of inorganic compounds PAC is not represented, but a series of inorganic polymers in general. PAC degree of polymerization is affected by many factors, the most direct, is one of its greatest impact hydroxide content and, therefore, it is usually the ratio of the Al and Cl or alkalinity (also known as basicity) as its characteristic parameters to describe the degree of polymerization, and especially the latter is more commonly used. Basicity PAC is defined by the following formula: degree of alkalization B (%) = [OH-] / 3 [Al3 +] × 100 wherein, [OH-] and [Al3 +] respectively hydroxide and the molar concentration of aluminum ions not difficult to find, alkalinity can be expressed as: alkalized degree B (%) = m / 3 n × 100 also has some habits with hydroxyl aluminum ratio ([OH -] / [Al3 +]) to represent, but its essence the same. Production methods and different conditions caused by the performance of various PAC control products are very different. Although more workers in their paper a keen interest, but they always PAC considered a common chemical sense, for which a particular product for testing, use and testing , expect it to achieve the desired variety of effects, but is not the case, the result is often contrary to the imagination, which is likely to cause them to lose confidence in the product. PAC products are usually the size of its alkalinity to distinguish, generally can be divided into three categories: low-basicity PAC (basicity 0 to 16.67%), the basicity PAC (basicity 16.67 ~ 50%) and high basicity PAC (basicity 50 to 83.3%). Typical wet end of the papermaking PAC for the majority of low or moderate basicity PAC, and PAC more for high alkalinity water or sewage treatment flocculants.
