Rhodium as a national strategic reserve metal, has the irreplaceable role of other metals, but its resources are mainly concentrated in some countries in South Africa, and rhodium resources are very scarce in our country. In the process of industrialization in China, a large number of rhodium-containing homogeneous spent rhodium catalysts are produced, of which rhodium content is much higher than that of ores, so it is particularly important to recover rhodium from rhodium-containing homogeneous spent catalysts. By referring to the relevant literature, this paper summarized the recycling methods and prospected its prospects. [ABSTRACT FROM AUTHOR]

In order to avoid the breakage and rough cut edge of tipping paper or wrinkled cigarettes caused by the tension fluctuation of tipping paper on the cutting drum in ZJ118 filter cigarette maker during production, a paper tension measuring roller was designed based on the principle of load cell, and force transmission analysis. The negative pressure control system for the cutting drum was developed by combining the BECKHOFF control system, PID adjustment technology and moving average filter algorithm with visual interface technology to realize the automatic adjustment and precise control of the negative pressure in the tipping paper cutting drum. The developed control system was tested on a ZJ118 filter cigarette maker in Xuzhou Cigarette Factory. The results showed that the frequency of tipping paper breakage decreased from 2.1 times/shift to 0.1 times/shift, and that of manual adjustment of negative pressure valves decreased from 0.5 times/shift to 0. The quality score of cigarette making increased from 98.7 to 99.4. This technology provides support for the stability of tipping paper transferring and the promotion of cigarette quality.

In order to improve quality, the effect of different modifying methods of Calcium carbonate (PCC) on reconstituted tobaccos in paper-making process was also studied, including direct addition, combining with starch and retention aids, modification with starch, and modification with tobacco stem fiber and starch. The results show that: 1) Direct additon, many calcium carbonate particles are relatively evenly distributed on the surface of base-sheet, but only small amounts of calcium carbonate particles affixing to fibers inside the base sheet. 2）Combining with starch and retention aids, calcium carbonate particles are distributed evenly in the whole base sheet. 3) Modification with starch, form large aggregates between calcium carbonate particles, which lead to a serious imbalance of PCC aggregates distribution in the base sheet. 4) Modification with tobacco stem and fiber starch, small pieces of PCC agglomeration are formed and the distribution of PCC agglomeration is relatively uniform in the base sheet. The retention of tobacco furnish and Calcium carbonate of these base sheets are improved gradually, which are prepared by four methods about mentioned. The pilot experiment results show that compared with old processes (direct addition), the deliveries of tar, CO and TPM in mainstream smoke of the sheets with new processes (modification with tobacco stem fiber and starch) have been brought down. The Calcium carbonate content of these sheets with new processes is improved significantly, from 6.3 % to 10.8 %, the Calcium carbonate retention of these sheets reach up to 72.0 %. Conclusion: The method of modification with tobacco stem and fiber starch can effectively improve the retention and distribution of calcium carbonate.

Japan’s detainment of Chinese fishing boats in 2010 and purchase of China’s Diaoyu Islands in 2012 tremendously harmed diplomatic relations between China and Japan, and had a negative impact on bilateral trade. This paper aims to analyze the impact of China-Japan relations and China’s participation in the Japan-centered East Asian production network on China’s export quality. The empirical research results based on the trade data of the mechanical and electrical industries indicate that China’s participation in the Japan-centered triangle trade enhances the quality of Chinese mechanical and electrical exports, and China should continue to strive for its integration into the Japan-centered East Asian production network.

To investigate the effects of cigarette paper splicing at different machine speeds on cigarette paper consumption and cigarette quality, the testing was carried out on ZJ118 and ZJ17 filter cigarette makers and the number of splicing failures, cigarette paper consumption, number of defective cigarettes, and cigarette physical indices at different machine speeds were compared. The results showed that: 1) The number of cigarette paper splicing failures decreased at lower machine speeds and diminished to 0 when the speed of ZJ118 and ZJ17 approached to 5 000 and 4 900 cig./min, respectively. 2) Cigarette paper consumption due to splicing was generally negatively correlated with the machine speed. 3) The number of defective cigarettes was extremely negatively correlated with the machine speed during splicing. 4) Reducing the machine speed during splicing resulted in inconsistent physical indices of cigarettes, extremely significantly increasing the standard deviation of cigarette weight, and significantly increasing the number of cigarettes that exceed the limits. 5) The optimal speed of ZJ118 and ZJ17 filter cigarette makers for splicing was 6 000 and 5 600 cig./min, respectively. These results provide references for optimizing the technical parameters of filter cigarette makers. [ABSTRACT FROM AUTHOR]

Aramid paper has been widely applied in the field of insulation because of its excellent electrical insulation performance, thermal stability and mechanical properties. However, the porosity of aramid paper is a weakness easy to b e broken down, which limits the performance and application expansion of aramid paper. To solve this problem, aramid papers w ere made from aramid floes and aramid fibrids with different proportions, and then coated with various insulating adhesives ( styrene-butadiene latex, polyvinyl alcohol, polyetherimide, silicone rubber, phenolic resin and urea-formaldehyde resin) to fabricate aramid-coated paper. The effects of fiber ratio and adhesive on the microstructure, electrical insulation properties, mechanical properties and thermal stability of coated paper were studied. The results show that coating adhesive can effectively improve the insulation properties and mechanical properties of aramid paper. Coated with phenolic resin, the breakdown strength of aramid-coated paper has the greatest improvement. When the ratio of aramid fibrids and aramid floes is 3 : 7, the breakdown strength and corona time of aramid-coated paper are up to 41 kV /mm and 434 h, respectively, which are 3. 6 times and 7. 3 times higher than that of the base paper. When the ratio of aramid fibrids and aramid floes is 7 : 3 and styrene-butadiene latex is used as adhesive, the tensile strength of aramid-coated paper reach 93. 7 N • m/g. More importantly, the coating method is a mature industrial production process in the paper industry, which will improve the possibility of industrial production of aramid-coated paper.

In this paper, isopropyl triolein titanate is used as the modifier to modify the cellulose nanofiber (CNF), then the modified cellulose nanofiber is coated on the surface of A4 paper, and cured to obtain isopropyl triolein titanate (KR-TTS) modified nanocellulose paper-based barrier coating. The hydrophobicity and mechanical property of blank paper, nanocellulose paper-based coating (CNF coating), isopropyl triolein titanate modified nanocellulose paper-based coating with different KR-TTS/CNF mass ratios (K-CNF coating) are characterized by video optical contact measuring instrument and electronic tensile machine. The results show that the K-CNF coating sample with a KR-TTS/CNF mass ratio of 151 has the largest water contact angle, which is 113.4° and 98.4° higher than that of CNF coating and has better hydrophobicity. Compared with the CNF coating, the tensile strength, elastic modulus and toughness of the coating sample are increased by 156.73%, 101.69% and 430.41 %, respectively. The sample exhibits better mechanical properties. The barrier performance test of the coating shows that the air permeability of the modified coating sample with a mass ratio of KR-TTS/CNF of 1:1 is 25234 s/25 cm", which is 46.65 times lower than that of the CNF coating. Water vapor transmission rate is 1 203.67 g/mJ • 24 h, which is 73.47% lower than the CNF coating, and the barrier performance is well. In addition, the SEM images of the modified coating samples show that the tightly wound 3T) network structure fills the paper pores that the CNF coating fails to fill, forming a denser coating and giving it better barrier properties and toughness.
