Di Wei and Utilization of Hemicellulose degeneration

Sugar-based composition, in addition to containing some glucose and a small amount of galactose and mannose-based, and thus contain more hydroxyl groups, particularly those with a more lively primary hydroxyl. When the semi-fiber cable with the degeneration after the surface sizing. Can promote hydrogen bonding to improve the binding force of fiber asked,[link widoczny dla zalogowanych], and to improve paper strength. Coral sand with the diol compounds with the formation of compounds the nature of the network, so the addition of borax the same in the two glycans and glycan molecules formed between the cis-hydroxy acid salt of such a complex, this network obviously will lead to complex cross-linking. Therefore, the application of borax ~ aspects of fiber cable can increase the hemicellulose and hemicellulose between the combination between themselves, thereby enhancing the stability of the bond,[link widoczny dla zalogowanych], but also asked the strength of the fibers produced. Applied on the surface before and after amine breakage corrugated paper samples were analyzed by scanning electron microscopy,[link widoczny dla zalogowanych], the results can be seen from the analysis,[link widoczny dla zalogowanych], after the specimen fracture surface sizing, the fiber was pulled out less. More fibers to be pulled off; and without the base paper surface sizing treatment fracture specimen was pulled out of the fiber more, indicating that / a 76/l2 Se <Hunan paper) 2 1998 Yu Mu Qi Park Extension B production workers warm I. Introduction With the large number of imported tobacco industry production units as well as high-speed cigarette smoking and health problems caused by people's attention more and more, the tobacco industry, cigarette paper, the quality requirements of the high strength, high permeability direction. In order to meet the development needs of the cigarette industry. I plant to improve the strength and permeability of cigarette paper, cigarette paper as to improve the quality of the focus, set up a high speed and high quality research and development group through the cigarette paper, cigarette paper of a series of foreign research and analysis, and based on my actual situation from the process plant and equipment for both active measures, and achieved good results. At present, I plant the production of high speed and high natural permeability through the cigarette paper to 6.68 ~ 10p ~ a / Pa. 8, and can reach 60 ℃, the products of several major tobacco factory by the province and outside use, fully able to meet the 5000-7000 branch / sub-units of high speed cigarette manufacturing, the volume of cigarette tar content after access to the actual level of cigarette paper imported by the user praise. Now the main high speed and high permeability of cigarette paper Received Date :1998 -02-15 to production test are summarized as follows: Second, the production process 1. Selection of raw materials related to product quality raw materials and production costs. I plant mainly the past, jute goods, supplemented by the production of cigarette paper pulp, can not increase permeability, and foreign cigarette papers are made of 100% bleached kraft pulp production, pulp quality goods, white, high strength, Since 1995, commodity pulp prices have been down, so we decided to use 100% wood pulp production of goods through high-speed cigarette paper. After a series of comparative tests, we chose the main raw materials, the Canadian fir softwood pulp and raw materials, mainly of eucalyptus hardwood pulp in Brazil. 2. Beating beating process to determine the production of high speed cigarette paper through the key. In order to find the best beating process, we passed several small experimental research and pilot production, the better the concentration of slurry and slurry related swelling, control, and fiber beating degree appropriate ratio, the production of cigarette paper not only strength and permeability high, and the uniform is good. (1) pulp slurry break to pieces and then soaked with water panel input hydrapulper the broken solution, it is a good solution pulp broken even. Softwood pulp and hardwood pulp slurry were used to pool the two horizontal storage, the storage time of 4 hours, so that the fiber swelling in water sufficiently so that the process is conducive to carve silk fibers in the beating broom, are full of fiber after beating Well, fine fiber debris and less fiber, pulp dewatering in the web faster, better permeability of the sheet. (2) Mongolian material condensed from hydrapulper to the slurry concentration is generally low, the surface sizing treatment, the specimens increased bond strength between the fibers. IV, Conclusion 1. In the original paper copy made of corrugated paper, with a half-fiber cable has been modified solution reed surface sizing, paper strength are more significant improvement can be expected to improve the grade corrugated paper products. When the modified half-fiber cable solution concentration was 9% to 11%, the amount of borax added 3% for optimal enhancement. 2. Scanning electron microscopy analysis showed that the surface sizing by the semi-fiber cable, the corrugated paper to improve the strength of the main reasons is due to semi-fibrous sheet penetrate more inside the connection by hydrogen bonds to improve the binding force between the fibers, which improve paper strength.
