Reaction vessels are categorized into high-temperature (150℃-300℃) and low-temperature (60℃-150℃) types. They are essential equipment used in the production of unsaturated polyester resins, phenolic resins, epoxy resins, ABS resins, and paints.
Shandong Longxing - Designated Production Unit for China National Chemical Equipment Corporation, specializing in the production of first, second, and third category pressure vessels and heat-conducting oil furnaces.
Shandong phenolic resin reaction kettle is composed of kettle body, kettle cover, jacket, stirrer, transmission unit, shaft seal device, and support. When the aspect ratio of the kettle is high, multi-layer impeller blades can be used, or customized to meet customer requirements. The jacket is set outside the kettle wall, or a heat exchange surface is installed inside the kettle, or heat exchange can be achieved through external circulation. The support base can be a support-type or lug-type. Gear reducers should be used for speeds over 160 RPM. The number, size, or other requirements for openings can be designed and manufactured according to customer specifications.
Typically, packed gland sealing is used under atmospheric or low pressure conditions, usually with pressures less than 2 kg.
2. Mechanical seals are typically used in general medium pressure or vacuum conditions, usually at negative pressure or 4 kg.
3. Magnetic seals are used in high-pressure or high-volatile medium conditions, typically above 14 kg of pressure. In addition to water-cooled systems for magnetic seals, other sealing types require a cooling water jacket above 120 degrees.
Shandong Phenolic Resin Reactor
Phenolic resin is a significant application as a binder. It is a multi-functional material that is compatible with a variety of organic and inorganic fillers. Properly designed phenolic resins have particularly fast wettability. After cross-linking, they provide the necessary mechanical strength, heat resistance, and electrical properties for abrasives, refractory materials, friction materials, and phenolic powder.
Water-soluble or alcohol-soluble phenolic resins are used to impregnate paper, cotton fabric, glass, asbestos, and similar materials to provide them with mechanical strength and electrical properties. Typical applications include electrical insulation and mechanical laminating, as well as filter paper for clutch discs and automotive filters.
Principle: When selecting a reaction kettle, the slurry type and baffle conditions are determined based on the mixing purpose and flow state, with the flow state decision being influenced by the viscosity of the mixing medium. The usage conditions are quite specific, encompassing not only the slurry type and mixing purpose but also the viscosity range of the propelling medium, the mixing speed range, and the tank capacity range. The proposed selection chart is also designed based on the mixing purpose and flow state during mixing, and its advantage lies in dividing the slurry type usage range according to the characteristics of different mixing processes, making the selection more precise.
