| Sumario: | Nowdays, algae considering marine ecosystem are regarded as producers and the first continuum that receives solar energy. Hence, they ensure the needed energy for the aquatic organism living. In global herbal division, algae have 1800 genus and 21000 types. Because of their presence in air rather than underground water, algae allocate larger arena to themselves in comparise to other herbage. Based on accomplished studies, it is rated that algae have more than 7000 types in terms of biological diversity. Algae are used a lot. They are consumed in food industry, dung preparation, medicinal consumption and etc. In this study the green algae nanocellulose was used to improve CMP resistance.For the preparation of pure cellulose, algae samples initially affected the soda process and then were affected by bleaching sequence.. Next, the obtained cellulose has been converted to Nano-cellulose by using ultrasonic method. Nano-cellulose from cladophora algae was mixed with CMP in the ratios of 2, 5 and 8 percent. Finally, handmade paper was made and its resistive (strengh) properties were studied and compared with the pure hardwood CMP pulp. The results revealed that 8% treatment group had the highest density, tensile strength, burst strength, and control group had the lowest amount. Furthermore, the highest tear strength was related to control group; while, the lowest tear strength was for 8% treatment group. |
