聚乙烯醇溶解加温，应保证车间生产设备正常运行情况下进行，避免进、回油降温幅度过大，造成用电量负荷大，烧毁变压器，造成安全责任事故。
接到加温通知后，在进、回油温度正常满足车间胶粉正常运行的前提下。启动导热油炉送、引风机待正常运行后，在设定进油温度接近或低于2—3℃，回油温度不低于200℃时，开启热交换器进、回油阀门(先开回油阀，后开进油阀)2—3丝。先预热，保证导热油炉回油温度不低于200℃，等预热30分钟后，再逐渐开启热交换器进、回油阀门，勤观察油炉进、回油温度的降低，及时调整进回油阀门，逐渐升压到3.5kg。压力达到3.5后，应勤观察换热器压力表读数的变化，应尽量保持3.5kg压力，根据读数变化必须及时调整进、回油阀门。但压力严禁超过4kg，严格避免造成人身安全伤害事故。
加温完成(配料岗位应及时通知)，不得完全关闭热交换器阀门，应开启进、回油阀门1—2丝。进行预热，尽量保持1kg压力。避免加温时进、回油温度降幅过大，影响车间车间生产设备正常运行。

Dissolution of the polyvinyl alcohol heating, should ensure that the workshop production equipment under the conditions of normal operation, avoid, return oil cooling rate is too large, resulting in electricity load transformer, burned, resulting in the accident.
Received notice in heating, the oil return temperature, normal to meet the normal operating under the premise of plant powder. Start the heat-conducting oil furnace feeding, draught fan for normal operation, in the setting of oil inlet temperatures near or below 2℃-3 ℃, the oil return temperature is below 200 ℃, open the heat exchanger, the oil return valve(to open the oil valve, oil valve after into) 2-3 wire. Preheat, ensure the heat-conducting oil furnace oil return temperature not lower than 200 DEG C, and preheating after 30 minutes, and then gradually open the heat exchanger, the oil return valve, the industrious observation oil into, oil return temperature decreases, the timely adjustment of inlet oil return valve, gradually boost to 3.5kg. Pressure reaches 3.5, should often observed heat exchanger pressure gauge reading changes, should try to keep the pressure of 3.5kg, according to the reading must be adjusted in time, change in the oil return valve. But the pressure shall not exceed 4kg, strictly avoid safety accidents.
After heating(ingredients post shall promptly notify), may not be fully closed valve should be opened into the heat exchanger, the oil return valve,1-2 wire. Preheating, try to keep the pressure of 1kg. Avoid heating inlet, oil return temperature falling too far, affect the normal operation of the equipment of workshop production workshop.
