Through microwave catalysis, it is beneficial to strengthen molecular vibration. Improve the thermal impact of reaction and enhance the rate of esterification reaction;
d. Ultrasonic catalysis: release the solution finished by microwave catalysis symphonious c into the ultrasonic reactor, which is closed and atmospheric pressure, and also full of nitrogen defense. The ultrasonic generator as well as mixing tool are set up on the ultrasonic reactor, and also the ultrasonic Generator, keep the frequency at 25kHz, keep it for 20min, then stop the ultrasonic generator, mix for 10min, after that stand still for 30min, keep the temperature of the ultrasonic activator at 265-270 ° C, repeat this action when; make use of ultrasonic cavitation Activity and mechanical action can increase the price of esterification reaction;
e. Pressurized catalysis: discharge the remedy completed by ultrasonic catalysis symphonious d into a pressurized activator. The pressurized activator is shut as well as loaded with nitrogen security. The service in the kettle was pressurized to 0.18 MPa, then stood still for 30 minutes, and then the stress in the pressurized response kettle was reduced to normal stress; the method of pressurization was made use of to enhance the rate of esterification response;
f. air conditioning: the solution that pressurizes and also militarizes in the step e is discharged right into the air conditioning kettle, and after the cooling is completed, the Rosin Material product 103.02 kg is acquired by the standard approach.
After inspection, the technological indications of Rosin Material products generated are: item shade (Hasson shade number) ≤ 50, acid worth ≤ 30mg KOH/g, softening point 100-105 ° C, thermal stability (in air): 180 ° C, 4h begin to alter shade.
A sort of technique of quick production Rosin Resin, consists of the complying with actions:
a. Crushing and grinding: Take 100kg of polished rosin with a pureness ≥ 99.2%, damage it as well as grind it to 90-120 mesh;
b. Preheating: Add rosin ground to 90-120 mesh symphonious an and include it to the preheating kettle. The pre-heating pot is shut as well as loaded with nitrogen security. Add 1.8 kg of glycerin, add 0.75 kg of fumaric acid into the pre-heating kettle, include 0.10 kg of stimulant zinc oxide into the pre-heating pot, warm while stirring, and preheat to 260 ° C after 1.2 h;
c. Microwave catalysis: the preheated option in the step b is released into the microwave reactor, the microwave reactor is a shut atmospheric pressure type, and also a microwave generator as well as a mixing gadget are installed, as well as the power of the microwave generator is 10kW, And it is full of nitrogen protection, turn on the microwave generator and mixing tool, and also mix while accomplishing microwave radiation. The period is 25 mins, and also microwave catalysis is finished; the mixing tool is suitable for the working environment of microwave radiation. With microwave catalysis, it is beneficial to enhance molecular resonance. Improve the thermal impact of reaction and also enhance the price of esterification reaction;
d. Ultrasonic catalysis: discharge the remedy finished by microwave catalysis symphonious c right into the ultrasonic reactor, which is impermeable and also atmospheric pressure, and also loaded with nitrogen security. The ultrasonic generator as well as stirring device are mounted on the ultrasonic reactor, and the ultrasonic Generator, maintain the regularity at 25kHz, keep it for 20min, then quit the ultrasonic generator, mix for 10min, after that stand still for 30min, maintain the temperature level of the ultrasonic activator at 265-270 ° C, repeat this action when; utilize ultrasonic cavitation Action and also mechanical activity can enhance the p
rice of esterification reaction;
e. Pressurized catalysis: discharge the option completed by ultrasonic catalysis in step d into a pressurized reactor. The pressurized activator is closed and full of nitrogen defense. The option in the pot was pressurized to 0.18 MPa, after that stood still for 30 minutes, and afterwards the pressure in the pressurized response kettle was lowered to regular pressure; the method of pressurization was used to increase the price of esterification reaction;
f. air conditioning: the service that pressurizes and militarizes in the step e is released into the air conditioning kettle, and also after the air conditioning is finished, the Rosin Material product 103.02 kg is acquired by the traditional technique.
After inspection, the technological indicators of Rosin Material items created are: item shade (Hasson color number) ≤ 50, acid worth ≤ 30mg KOH/g, softening factor 100-105 ° C, thermal stability (in air): 180 ° C, 4h start to transform shade.
