Manufacturing of BWP-Grade Plywood from Resin Adhesive Using Animal Protein (Glue) by Partial Replacement of Phenol
Abstract: Abstract This paper presents the development of plyboard using phenol–glue–formaldehyde (PGF) resin and their basic mechanical properties. Phenoplast and aminoplast-based resins is the important adhesive for the manufacturing of boiling water proof (BWP) grade, shuttering and moisture resistance plywood. Environmental concerns and higher cost of petroleum-based resins have resulted in the development of technologies to replace phenol partially by biomaterials for the manufacturing of resin adhesive. Natural bio-based materials such …

MISCIBILITY EVALUATION OF POLYSTYRENE AND POLY(METHYL METHACRYLATE) BLENDS: ANALYSIS OF MECHANICAL, THERMAL, MORPHOLOGY, AND VISCOELASTIC PROPERTIES
Abstract: Partially miscible blend of polystyrene (PS) and poly(methyl methacrylate) (PMMA) was successfully prepared employing melt blending technique. In order to impart miscibility, the processing was carried out at temperature above upper critical solution temperature (UCST) as studied from cloud point measurements. The complex modulii and viscosity derived from melt rheology analysis as a function of angular frequency were also used to study the effect of PMMA loading on the miscibility …

Deposition and characterization of poly(o-anisidine)/TiO2Nanocomposite for gas sensing application
Abstract: The Poly(o-anisidine) (POA) and Titanium dioxide POA (POA/TiO2 ) composite thin film based for gas sensing application are synthesized. Pure POA and POA/TiO2 composites with 20wt% of TiO2 were synthesized by chemical oxidative polymerization of o-anisidine using ammonium persulfate in acidic medium at 0-50C. Thin films of POA and POA/TiO2 composites were deposited on glass plate by dip coating method to prepare the chemiresistor sensor. The structural and optical properties …

Kinetic Study of Polyester Derived from Glycolyzed PET Waste With Varied Composition
Abstract: In this investigation, the production of secondary value-added products, such as saturated polyester, derived from the glycolysis of poly(ethyleneterephthalate) (PET) is examined as an effective way for PET recycling. The glycolyzed PET (GPET) obtained was reacted with mixture of phthalic anhydride and glycol with varied composition and their reaction kinetic were studied. During polyesterification it was observed that degree of polymerization (DPn) and extent of reaction (p) is increased, while …

A Review on Processing of Waste PET (Polyethylene Terephthalate) Plastics
Abstract: Solid waste is essentially waste produced in our homes, businesses and industrial sources. Globally waste production is growing in volume and in toxicity. Plastic waste is a nature threat that is of great concern to the researches to refuse and reuse. The man-made systems emphasize the economic value of materials and energy where production and consumption are the extensive economic actions. Such systems are a threat to the environment as …

Drag Reduction Annular Flow with Poly Acryl Amide Additive
Abstract: Drag reduction studies have been showed in annular flow with polyacrylamide additive. The percentage drag reduction in annular pipe flow ranges between 85–98% as the diameter increased from 0.02 to 0.033 m. The percentage drag decrease of 89 to 98% is detected as the polyacrylamide concentration is varied from 50 to 200 ppm. The correlation for drag reduction and Reynolds number is presented here under DR = 2.06Re-0.037. Keywords: Drag …

Enhancement of Fire Retardancy Properties of Plywood by Incorporating Silicate, Phosphate and Boron Compounds as Additives in PMUF Resin
Abstract: Wood is one of the supreme sustainable, naturally growing materials that consist principally of combustible organic carbon compounds. Since plywood are widely used now a day especially in buildings, furniture and cabinets. Since the demand of plywood with fire retardancy properties has been increasing over last years, the objective of this study is to improve the fire retardancy of Wood Panel Products by adding Tricresyl phosphate, Di-Sodiumocta Borate and Sodium …

Environment Friendly, Exterior Grade Resin Adhesive from Phenol-Animal Glue Formaldehyde (PGF)
Abstract: Phenoplast and aminoplast based resins are the important adhesive for the manufacturing of marine grade, shuttering and moisture resistance plywood. Environmental concerns and higher cost of petroleum based resins have resulted in the development of technologies to replace phenol partially by biomaterials for the manufacturing of resin adhesive. Natural bio-based materials such as tannin, CNSL (cardanol), lignin soya etc. are used as partial substitution of phenol. This paper presents the …

Green Adhesive—Using Glyoxalated Lignin and Hydrogenated Resin as Ecologically Safe Wood Adhesive for Interior Plywood
Abstract: Petroleum-based adhesive such as urea formaldehyde and phenol formaldehyde resin dominates adhesive market which releases formaldehyde and VOC to the environment. The purpose of this study is to develop an adhesive based on isocyanate in combination with compounds from renewable sources like lignin, protein and starch. Adhesive formulation was developed by incorporation of hydrogenated resin, corn starch/PVOH emulsion with glyoxalated lignin (GL) and evaluation properties of the adhesive with plywood …
