Surface and optical properties of calcium carbonate paper

The article investigates the surface and optical properties of calcium carbonate paper obtained at the UzbekChinese enterprise Fergana stone paper company (Uzbekistan), in order to identify the possibility of their use at printing enterprises for printing multicolor products using traditional printing methods. According to the results of a quantitative assessment of the surface quality by the indirect Beck method, we can say that paper sample 1 has a smoothness like coated paper (750–1500 s), paper samples 2 and 3 – like calendered paper, so that these paper samples can be recommended for prints with increased quality requirements. Smaller values of roughness Ra and small depressions, expressed by darkening in the topographic AFM images, characterized sufficient homogeneity and density of the structure. It was also revealed that the surface of the paper samples has a high ability to specularly reflect the incident light, since the percentage of surface reflection is similar to that of coated papers. Samples of paper have a whiteness of about 90 % and do not have a tint, since the difference between the maximum and minimum values of the reflection coefficients on a white stack is not more than 10 %. The tested paper samples can be recommended without restrictions for double-sided printing, since the opacity index is more than 92 %.

Low Cost Activated Carbon for Removal of NOM and DBPs: Optimization and Comparison

Higher concentrations of disinfection byproducts (DBPs) in small water systems have been a challenge. Adsorption by tailored activated carbon (AC), developed from waste materials of a pulp and paper company using optimization of chemical activation by nitric acid followed by physical activation and metal coating, was tested for the removal of natural organic matter from water using synthetic and natural water. AC was coated with aluminum and iron salts in a ratio of 0.25 to 10.0% of metal: AC (wt: wt%). The optimization of dosage, pH, and time was performed to achieve the highest adsorption capacity. The modified AC of 0.75% Fe-AC and 1.0% Al-AC showed 35–44% improvement in DOC removal from natural water. An enhancement of 40.7% in THMs removal and 77.1% in HAAs removal, compared to non-modified, AC were achieved. The pseudo-second order was the best fitted kinetic model for DOC removal, representing a physiochemical mechanism of adsorption.

Madawaska Rebellion

This chapter discusses the workers at Fraser Paper Company that revolted against an English management regime that forced speed-up, retracted employment promises, and belittled both union leaders and shop-floor workers. It details how workers, their families, and community members fought back Fraser Paper, using civil disobedience that spiraled into a violent confrontation with mill leaders and state and local police. It also recounts how Fraser Paper was initially run by founders and their sons, along with a stable cadre of professional executives who joined the paper company beginning in 1932. The chapter refers to John “Pete” Heuer, who was the president and chief executive at Fraser Paper who introduced a harsh management approach and battled the mill's unions. It mentions the workers' militant response against Fraser Paper that was shaped through the norms of workplace contractualism and a remarkable local Francophone culture.

Fear and Loathing on the Low and High Roads

This chapter deals with the national and international competition that was eroding companies' pricing power and market shares by the mid-1980s. It talks about workers in a mature industrial state like Maine who were expected to see their paper industry jobs disappear as production moved overseas and work was automated at home and abroad. It also discusses how the national companies that owned Maine's mills made radical demands on workers and attacked traditional union contracts outright. The chapter cites that Boise Cascade and International Paper Company (IP) provoked strikes by making extreme, untenable demands on workers in their Rumford and Jay, Maine, mills in 1986 and 1987. It probes the union-busting campaigns conducted by Boise Cascade and IP that defined what economists call the low road, which clobbered workers in the quest to quickly raise profits.

RANCANG BANGUN KOMPONEN TUMPUAN PENDORONG KAYU CHIP PADA CHAIN FEED TO CHIPPER

Chain Feed to Chipper is one of the equipment in the Wood Handling machine of the paper company PT. Indah Kiat Pulp & Paper Perawang, whose main function is to carry logs before chipping by the Chipper machine as raw material for making Pulp, but in the process it works Chain The feed has not been damaged at the deadline, namely the bearings of the Chain Feed made of solid iron are damaged, loose and enter the Chipper engine, thus damaging the parts in the Chipper engine, this of course requires a large cost in repairing the parts that are Therefore, research on the cause of damage or bearing limits of the Chain Feed was carried out and finally redesigned the Chain Feed, namely redesigning it by removing the bearings on the chain, by designing adding a triangular plate to replace the bearings as a means of carrying logs on the chain. Chain Feed. After re-designing the Chain Feed, the risk of damage to the bearings entering the Chipper engine is no longer there

Potential benefit for production management of a pulp and paper company from using an ft-nir analyzer

Effects of Green Technology on Firm’s Profitability and Solvency: Exhibit from the Textiles Industry of Bangladesh

In recent years there has been increasing advocacy regarding the perception that turning green is good for the corporation and thus for the whole economy. Green technology is nowadays a popular term in any industry but the stakeholders always ask a question of whether the company benefits from using green technology or is there any financial gain? This question remains unanswered in our country, and because of that new entities are not willing to adopt green technology especially in the textile sector. This paper shows that the companies using green technology having financial benefits than the companies not using green technology. In this paper, we used financial performance measurement techniques to find out companies' financial health. This study has taken data of 43 listed companies of Dhaka Stock Exchange. Then it divides the data into two groups, a group accustomed to green technology and a group not accustomed to green technology. Firstly, we used profitability ratios (ROS, ROA, ROE) to find out two groups of companies' position. Profitability ratios vary significantly from one group to another. Secondly, we used solvency ratios (Debt asset ratio and debt-equity ratio) and find result almost similar but the result changes with the passages of time through the payment of installment. So from the study, it can be said that profitability is positively related to the adoption of green technology. Thus, by studying this paper company will be keen to adopt green technology in their organization. This paper will also help existing companies to improve the existing technology.
