Since the macroporous resin is widely used in pharmaceutical and natural plant extraction and separation of active ingredients such as saponins, flavonoids, lactones, alkaloids and other macromolecular compounds. Ginseng saponins . Panax saponin, Gynostemma saponins, diosgenin , stevia saponin, glycyrrhizin, the flavonoids butter, hawthorn flavonoids. Astragalus saponin, hesperidin, epimedium flavonoids, soy isoflavones, polyphenols , digitalis cardiac glycosides , ephedra powder, grapefruit glycosides.Maodongqing glycosides, alkaloids yew , a variety of natural pigments , such as traditional Chinese medicine extracts and biochemical products, pharmaceutical purification , separation, recycling has a good effect. And antibiotics, vitamins, amino acids , protein purification , chemical and biological pharmaceuticals have a very wide range of applications . Now, the synthesis and application of acrylic emulsion has become some of the research institutes , universities and research focus.
According to the design plan , the design of the annual output of 600 tons acrylate resin adsorption macroporous process design . Through access to a large amount of literature and cognitive training , methyl acrylate , dichloroethane, vinyl benzene, petroleum ether . BPO production technology, production equipment and design a scientific proof .
For acrylic macroporous resin production process , there are two step reaction: methyl acrylate as a monomer , pinylbenzene as a crosslinking agent .BPO for the suspension polymerization initiator , and then subjected to hydrolysis by adding sodium hydroxide solution . According to these types of products in all aspects of the performance of different specifications , the design reference standards, select the appropriate formulation and manufacturing process conditions.
Important feature of this design is the use of a macroporous resin acrylate integrated production , reduce production costs and increase flexibility. Synthetic adsorption resin by suspension polymerization of macroporous acrylate component is more complex , in addition to the monomer , a crosslinking agent , initiator and water , the product according to the material and the performance requirements needed a pH buffer , pH adjusting agent . The basic design consists of two steps of the recipe , including the specific optional components , the amount and the basic specifications of the components and the like.
The design for the production of acrylic macroporous resin two -step main production equipment for the equipment selection and design , and to determine the appropriate technical parameters. The main equipment involved are polymerization reactor, measuring cans , foam trap , dryers , heat exchangers, centrifuges , cyclones , etc., according to the actual production conditions, provided the selected device and the corresponding manufacturers. Among them, the polymerization reactor design is the key. The design of the polymerization reactor design refinement , include material, kettle lid , stir , choose a jacket , seal , etc. . Achieve compliance with the conditions , safe, reliable , economical, easy to operate and so on principle , to determine the heat flow , the flow rate , the heat carrier , the final temperature of the heat exchanger and heat transfer area on the basis of estimation of the heat exchanger .
Combined with the actual choice of the production process and product solutions , also carried out of the materials and energy balance calculations. Resin adsorption process design workshop conducted a workshop layout design based on 600 tons of silicon acrylate big hole . In this design, factory workshop using rectangular double the plant. Plant size ( length × width × height ) of 18m × 6m × 10m. Rectangular plant easy to make the whole plant layout, land conservation , convenient device arranged to facilitate arrangements for transportation and entrance, there are more walls to the use of natural lighting and ventilation design . The acrylic emulsion plant height higher, using double- high plant utilization , and facilitate the design with space to expand production .
