Example Embodiment
[0069] Example 1
[0070] A cellulose sponge continuous production process, comprising the following steps:
[0071] A. Glue making: take pulp with methyl cellulose content ≥ 93% and dynamic viscosity ≥ 10mpa.s as raw material, after soaking in dipping bucket 1 for alkalization, pressing machine 2 for crushing and yellowing machine 3 for vacuum yellowing, viscose is obtained. ; Among them, in the yellowing machine 3, the CS2 addition ratio is 38%, and the vacuum degree is -0.085MPa;
[0072] b. Weighing: take the ratio of Glauber's salt to the obtained viscose as 3.2, respectively weigh the Glauber's salt and the gained viscose; wherein, the particle size of Glauber's salt is 2mm;
[0073] c. Stirring: place the weighed Glauber's salt and the obtained viscose in the crankshaft mixer 4, and stir for 15 minutes under the condition that the rotating speed is 60 r / min and the temperature is less than or equal to 40 °C, to obtain a mixture;
[0074] D. Discharging: the gained...
