Problems solved by technology

Rosin has excellent properties such as thickening, emulsifying, softening, moisture-proof, anti-corrosion, and insulation. The disadvantage is that it tends to crystallize in solvents.
The viscosity of rosin is very good, especially the pressure sensitivity, fast viscosity, and low temperature viscosity are very good, but the cohesion is poor
Because rosin contains double bonds and carboxyl groups, it has strong reactivity, so it is unstable to light, heat, and oxygen, showing poor aging resistance, poor weather resistance, and prone to powdering and discoloration. Rosin is very fine Mixture of dust and air may cause explosion hazard

Embodiment 1

[0024] A rosin production and processing process, the process comprising: a fat storage tank 1, the fat storage tank 1 is connected to a metering tank 2, the metering tank 2 is connected to a dissolving pot 3, and the dissolving pot 3 is respectively connected to a waste residue recovery device 4 and a transition pot 5;

[0025] The transition pot 5 is connected with the primary filter 6 and the waste liquid recovery device 7 respectively, the waste liquid recovery device 7 is connected with the metering tank 2, the primary filter 6 is connected with the clarification tank 8 and the waste residue recovery device 4 respectively, and the clarification tank 8 is connected with the fine filter The device 9 is connected, the fine filter 9 is connected to the storage tank 10, and the storage tank 10 is connected to the vacuum distillation pot 11;

[0026] Dissolving pot 3, clarification tank 8, and vacuum distillation pot 11 are all connected with steam generator 12, and steam genera...

Embodiment 2

[0029]On the basis of embodiment 1, on the pipeline that is connected with condenser 14 on the dissolving pot 3, all be provided with pipeline sight glass; The bore sight glass can observe the completion of grease pressing.

Embodiment 3

[0031] On the basis of embodiment 1-2, between the product collection device 15 and the vacuum distillation pot 11, an incense trough is arranged, and a heat dissipation plate is arranged in the incense trough; the setting of the heat dissipation plate shortens the time for putting incense, improves product quality, and changes Raw material sending incense is placed too long in the vacuum distillation pot 11, causes the color of gum rosin to become darker.

Description

technical field [0001] The invention relates to the technical field of rosin processing, in particular to a rosin production and processing technology. Background technique [0002] Rosin refers to a non-volatile natural resin obtained from pine rosin through different processing methods. Rosin is an important chemical raw material, widely used in soap, paper, paint, rubber and other industries. According to its source, rosin is divided into three types: gum rosin, wood rosin and tall oil rosin. Gum rosin is also called relaxing incense, with light color, large acid value and high softening point; rosin is also called leaching rosin, its quality is not as good as gum rosin, its color is dark, its acid value is small, and it is easy to crystallize from certain solvents; tall oil rosin is also It is called tall oil rosin. Rosin is a transparent, brittle solid natural resin, which is a relatively complex mixture, consisting of resin acid, a small amount of fatty acid, rosin ...
