Effect of waste rubber powder as filler for plywood application
Polish Journal of Chemical Technology - Tập 17 Số 1 - Trang 41-47 - 2015
Huei Ruey Ong, Md. Maksudur Rahman Khan, Abu Yousuf, Nitthiyah Jeyaratnam, D.M. Reddy Prasad
Abstract The study investigated the suitability of waste rubber powder (WRP) use as filler in adhesive formulation for plywood application. Melamine Urea Formaldehyde (MUF) was employed as resin for formulating the wood adhesive. To improve chemical properties and bonding quality of adhesive, WRP was treated by different chemicals like 20% nitric ac...... hiện toàn bộ
Electrically conductive acrylic pressure-sensitive adhesives containing carbon black
Polish Journal of Chemical Technology - Tập 13 Số 4 - Trang 77-81 - 2011
Zbigniew Czech, Robert Pełech, Agnieszka Kowalczyk, Arkadiusz Kowalski, Rafał J. Wróbel
Electrically conductive acrylic pressure-sensitive adhesives containing carbon black Acrylic pressure-sensitive adhesives (PSA) are non electrical conductive materials. The electrical conductivity is incorporated into acrylic self-adhesive polymer after adding electrically conductive additives like carbon black, especially nano carbon black. After an...... hiện toàn bộ

Adsorption of anionic dyes onto natural, thermally and chemically modified smectite clays
Polish Journal of Chemical Technology - Tập 16 Số 4 - Trang 33-40 - 2014
Joanna Kyzioł-Komosińska, Czesława Rosik‐Dulewska, Magdalena Pająk, Iwona Krzyżewska, Agnieszka Dzieniszewska
Abstract The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifications on the amount of bonded dy...... hiện toàn bộ
Biosorption Performance of Biodegradable Polymer Powders for the Removal of Gallium(III) ions from Aqueous Solution
Polish Journal of Chemical Technology - Tập 17 Số 3 - Trang 124-132 - 2015
Ching‐Hwa Lee, Hang-Yi Lin, Elon I. Cadogan, Srinivasa R. Popuri, Chia‐Yuan Chang
Abstract Gallium (Ga) is considered an important element in the semiconducting industry and as the lifespan of electronic products decrease annually Ga-containing effluent has been increasing. The present study investigated the use of biodegradable polymer powders, crab shell and chitosan, in the removal of Ga(III) ions from aqueous solution. Ga(III)...... hiện toàn bộ
