Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale
Soy- Based Flexographic Ink For Linerboard Printing, Rahul Ramchandra Pingale
Masters Theses
Many printing inks use volatile solvents in the formulation, which are hazardous to the environment from emission of VOC’s and at the same time, synthetic resins in these inks are not biodegradable. These problems with the fluctuating and rising price of petroleum are main reasons to look for new resources for making more environmentally friendly printing inks. The majority of the commercially available water based inks are formulated based on using acrylic resins, synthetic colorants, solvents/water and additives, which are the common main components for formulating printing inks. In this research, soy proteins were tested for their suitability to partially …
Papermaking Factors Affecting Lateral Web Position During Commercial Heat Set Web Offset Printing, George W. Shields
Papermaking Factors Affecting Lateral Web Position During Commercial Heat Set Web Offset Printing, George W. Shields
Masters Theses
The interaction of water with paper plays a role in web handling characteristics during commercial heat set web offset printing. Water absorption leads to lower web tension for a given strain.
This research investigates paper properties and their role in preventing lateral web movement from cross machine air flows in the drying section during normal printing operations. Tensile properties of sheets are measured at various moisture contents and then used to determine the equilibrium stress-strain relationship for papers at moisture contents typical of heat set web offset printing. Permeability, fiber orientation and tensile stiffness are evaluated against lateral web movement …
Lignin Maximization: Analyzing The Impact Of Different Feedstocks And Feedstock Ratios Using Organosolv Fractionation, Marc Banholzer
Lignin Maximization: Analyzing The Impact Of Different Feedstocks And Feedstock Ratios Using Organosolv Fractionation, Marc Banholzer
Masters Theses
Over-exploitation of fossil fuels coupled with increasing pressure to reduce carbon emissions are prompting a transition from conventional petrochemical feedstocks to sustainable and renewable sourced carbon. The use of lignocellulosic biomass as a feedstock for integrated biorefining is of current high interest, as separation into its component parts affords process streams of cellulose, hemicellulose and lignin, each of which can serve as a starting point for the production of biobased chemicals and fuels. Given the large number of potential sources of lignocellulosic feedstocks, the biorefinery will need to adapt to the supplies available over a normal growing season. Of particular …
The Effect Of Wet End Operations On Sizing Loss In Alkaline Papers, Suresh B. Cherukuri
The Effect Of Wet End Operations On Sizing Loss In Alkaline Papers, Suresh B. Cherukuri
Masters Theses
Changes in wet end of alkaline papermaking affect the size development as well as sizing loss. These changes include pH, alkalinity and type of filler used. Precipitated and ground varieties of carbonate fillers and the alkalinity associated with · them are believed to be the causes for the gradual sizing loss in alkaline papers due the accelerated hydrolysis reaction of sizing chemicals at higher alkalinity.
Precipitated and ground calcium carbonate fillers are used as fillers and compared to non carbonate filler such as kaolin clay for their response to size development and sizing loss at lower and higher alkalinity ranges …
