Embodiment Construction
[0004] 1. Cut the kenaf into small pieces of 2-5cm, soak and transport to the thread rolling machine to twist into fiber bundles.
[0005] 2. Transport the fiber bundles to the stainless steel container, add the chelating agent and penetrating agent at the same time, stir evenly, and when the steam reaches 80°C, add the potassium-based hydrogen peroxide generated by the hydroxide in the ion-exchange membrane switch, and introduce oxygen at the same time , The hydroxyl radicals and active oxygen radicals generated under the catalysis of ultraviolet light break the chromophoric groups of lignin, soften and disintegrate the fibers, and become coarse pulp with a whiteness of 60%ISO-85%ISO.
[0006] 3. After the coarse pulp is treated by a deflaker, a refiner, a screening machine and a slag remover, it becomes a chlorine-free and pollution-free clean pulp.
[0007] 4. After the pulping waste liquid is filtered by the hollow membrane, it can be reused in the dispensing, washing, scr...
