Alkyd resin is a kind of synthetic polymer, is a kind of preparation of resin performance quality suitable for surface coating by polymer components in control system. Alkyd resin by polycondensation reaction by polyol, polybasic acid and fatty acid as main component to prepare the.
Alkyd resin is one of the first synthetic resin used in coatings industry, is now widely used paint is coated with resin. The wide raw material sources, variety, good through all kinds of modified with various performance characteristics, so it is applied in almost all types of coatings.
In recent years due to the stable development of the global economy, the alkyd resin continued high demand. Alkyd resin emerge in an endless stream of new research achievements and varieties, application in expanding and extending, the future market prospects of alkyd resin is very considerable.
The design is an annual output of 1000 tons of design workshop alkyd resin requirements of annual: 1000t, operation period of 300 days / years, the process calculation, equipment selection, a process flow chart, workshop layout.
Production by solvent method, with intermittent operation mode, the raw material choice, process flow chart. Through this design, according to the synthetic process of master products step in accordance with the terms of the familiar with alkyd resin product design, formulation design of alkyd resin, the influence of the physical parameters related to the properties of resin and solution, and learn about the modified alkyd resin and its application scheme. The design process can have a reasonable innovation.
Process: general aspects of learning and research, this design is mainly to alcohol solution and solvent method to produce alkyd resin. This design uses special alkyd resin reactor, the reactor with jacket type heat transfer, heating method for the thermal oil circulation heating, and heat conduction oil directly by the electric heating tube heating; cooling method for cooling water cooling, the agitator selection of turbine type agitator. Characteristic of this process is the largest with packing tube instead of the commonly used steam outlet pipe.
