Study on Magnesium Hydroxide-based Hydrogen Peroxide Bleaching Process of Nigra Poplar CTMP Qiang Zhao 1,2, Dezhi Sun *2, MingYang Zhang 1, Sumin Kang 1 1.College of material Science and Technology,Beijing Forestry University.China 2.
Introduction Nigra poplar is widely used as an important material for pulp and paper industry in China.
Experimental Material The CTMP sample of Nigra poplar was provided by Shandong HuaTai Paper Corp.
As shown in Tab.4, the higher yield of bleached pulp were obtained with Mg(OH)2-based process than that with NaOH-based process, which indicated that the dissolution of organic materials from pulp fibers during Mg(OH)2-based bleaching was less.

Due to the concentrated heat generated by the laser beam, there are many resolidified materials and contaminants inside the Data Matrix symbol.
The readability of the Data Matrix code can be improved if the depth of the mark is increased during the product in-service, which may have an adverse effect on substrate materials.
As can be seen in Fig. 3(a) and (b), there are no new diffraction peaks or the displacement of diffraction peaks, so the nature of the phases and structures of substrate materials is unmodified and undeformed.
