How to control the reaction temperature of BIGGER water based adhesive spray better?
BIGGER water-based spray adhesive is the hottest environmental protection spray products.Do you know how to control the reaction temperature of bigger water-based spray better?
1.If there is a large difference between the temperature in the kettle and the required temperature in the process, the temperature should be heated up and the drip addition should be stopped at the same time.Forcing a drip increases the risk of a "blow-pot".
2.Hotter than the technological requirements for 1 ~ 2 ℃, can continue to add pre emulsion and initiator;At the same time, regular cooling is adopted to cool down.In general, reduce 0.1 ℃, the thermometer can stop;Then the reaction liquid will naturally reduce 2 ~ 3 ℃ temperature.
3.Hotter than technological requirements for more than 3 ℃, should immediately cool, at the same time to stop and in the process of the emulsion and the initiator;If the temperature in the kettle is much higher than the required temperature, the temperature should be cooled and cooled immediately, and the drip addition should be stopped.Evacuate all staff at the same time to avoid danger.
4.If the reaction temperature is too high, the polymerization rate will increase, the average molecular weight will decrease, the number of latex particles will increase, and the particle size will decrease.At the same time, the Brownian motion of latex particles increases and the stability of emulsion decreases.When the temperature is greater than the turbidity point of the emulsifier, the emulsifier loses its stabilizing effect, leading to demulsification.Therefore, the reaction temperature must be strictly controlled according to the process design requirements.
5.1 ~ 2 ℃ temperature below process requirement, can continue to add pre emulsion and initiator;At the same time, the method of regular heating is adopted.In general, increased 0.1 ℃, the thermometer can be stopped;Then naturally high reaction temperature of 2 ~ 3 ℃. This is known as the "Matthew effect".
6.If the equipment is defective, it should be improved immediately.Key inspection: cold source and heat source, thermowell position.
7.There is a systematic error in the thermometer.Should choose accurate to 0.1 ℃ electronic digital display thermometer.
8.The droplet acceleration is not well controlled.Drip addition should be carried out in strict accordance with the production process.
9.To master the exothermic law of the reaction process and the characteristics of the equipment can prevent the disease before it occurs.
