• I-pulp yokhuni

Isinyathelo 2: Ukwenziwa kwe-Alkalization

I-cellulose isabela namakhemikhali e-alkaline ukuze isebenze amaqembu e-hydroxyl.

Isinyathelo 3: Ukushintshashintsha kwe-Ether

I-cellulose isabela nama-ethylating agents ukuze ilethe amaqembu e-ethyl.

Isinyathelo 4: Ukuhlanzwa

Umkhiqizo uyagezwa futhi uhlanzwe.

Isinyathelo 5: Ukomisa Nokugaya

Kukhiqizwa i-EC powder yokugcina.
