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

[0028] The present invention provides a kind of rosin production and processing technology, such as figure 1 As shown, the process includes: a grease storage tank 1, a grease 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 the waste residue recovery device 4 and the transition pot 5;

[0029] The transition pot 5 is respectively connected with the primary filter 6 and the waste liquid recovery device 7, the waste liquid recovery device 7 is connected with the metering tank 2, the primary filter 6 is respectively connected with the clarification tank 8 and the waste residue recovery device 4, and the clarification tank 8 is connected with the fine filter The filter 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;

[0030]The dissolving pot 3, the clarifying tank 8, and the va...

Embodiment 2

[0033] On the basis of Example 1, the pipes connected with the condenser 14 on the dissolving pot 3 are all provided with a pipe sight glass; the condenser 14 is connected with a pipeline business pipe sight glass, which can observe whether the oil-water mixture is extracted; The borescope can observe the completion of grease pressing.

Embodiment 3

[0035] On the basis of Example 1-2, a fragrance release groove is provided between the product collection device 15 and the vacuum distillation pot 11, and a heat dissipation plate is arranged in the fragrance release groove; the setting of the heat radiation plate shortens the fragrance release time, improves product quality, and changes the The raw material is placed in the vacuum distillation pot 11 for too long, resulting in a darker color of gum rosin.

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 by different processing methods using pine resin as raw material. Rosin is an important chemical raw material, widely used in soap, paper, paint, rubber and other industries. Rosin is divided into three types: gum rosin, wood rosin and tall oil rosin according to its source. Gum rosin is also called relaxing fragrance, with light color, high acid value and high softening point; wood rosin, also known as leaching rosin, is not as good as gum rosin, dark in color, low in acid value, and easy to crystallize from certain solvents; tall oil rosin Also known as tall oil rosin. Rosin is a transparent and brittle solid natural resin, which is a relatively complex mixture, consisting of resin acid, a small amount of fatty acid, rosin anhydride and n...
