实施例3：
一种可降解海绵制品的制作方法，它选用木浆粕和竹浆粕的混合浆粕作为主要原料，经过浸泡、压榨、老化、黄化、粘胶、混料、发泡成型和水洗工序后，制成木纤维素的可降解海绵制品，其中：
a)所述的浸泡工序中，在浸渍桶中加入氢氧化钠和混合浆粕两种原料一起混合，其中氢氧化钠和混合浆粕的重量比例为2.5：1；所述的混合浆粕中木浆粕占比75％，竹浆粕占比25％；浸渍桶内的浸渍温度为35℃，且在高速旋转条件下，且浸渍桶可以在间歇和连续两种工作状态下进行；
b)所述的压榨工序中，将浸泡之后的浆液投入到压榨机中，挤出过多的的氢氧化钠溶液，得到压缩过后的碱纤维素块；压缩过后的碱纤维素块干度是原来浆液的3.5倍，且压缩后的碱纤维素块通过碾磨机，形成20mm的碱纤维素块；
c)所述的黄化反应工序中，先将碱纤维素块置放2小时进行老化处理，然后进行黄化反应；将静置后的碱纤维素块放入一个真空反应器中，通入二硫化碳气体进行黄化反应，通入二硫化碳气体的量是碱纤维素块质量的1.5倍；反应后得到黄原酸酯；所述的真空反应器的反应温度为40℃，绝对压强为0.08Mpa，反应时间140；
d)所述的粘胶工序中，将所述的黄原酸酯与另外的竹浆粕、木浆粕和水一起加入捏合机中进行混合制成粘胶料，其中粘胶料中含有40％的黄原酸酯、4％的竹浆粕、3％的木浆粕，余为水；
将所述的黄原酸酯先进行粗研磨机进行研磨后，再与竹浆粕和木浆粕混合的纤维素放入水中静置4小时，再一起加入捏合机中进行混合制成粘胶料；
e)所述的混料工序中，将粘胶料与硫酸钠晶体、色粉色带进行混合并制成可加热发泡的海绵混合物，其中海绵混合物中含有28％粘胶料、71％硫酸钠晶体、1色粉色带；
将所述粘胶料先静置7小时，再与硫酸钠晶体、色粉色带进行混合；所述的海绵混合物是在压力的挤压下通过弯曲设置的管道进入发泡模具中；
f)所述的发泡成型工序中，将海绵混合物放置于发泡模具中，直接将海绵混合物通电加热凝结，制成海绵块；
g)所述的水洗工序中，将发泡后制成的海绵块至少通过弱盐洗、酸洗以及漂白洗三道工序后制成海绵制品；
所述的弱盐洗、酸洗以及漂白洗三道工序均通过依次布置的三个工作室，经工作室上部设置的滴管式或直淋式加液方式实现的。
