 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : The Effect of Curing Parameters on the Mechanical Properties of Styrene-NR Elastomers Containing Natural Rubber-Graft- Polystyrene) ผู้เขียน:ดร.ธาริณี นามพิชญ์, รองศาสตราจารย์ , Polchit Buakaew สื่อสิ่งพิมพ์:pdf AbstractThe copolymerization of styrene on natural rubber latex was prepared by an emulsion polymerization using potassium persulfate and sodium laurylsulfate as an initiator and emulsifier, respectively. The vulcanization characteristics of styrene-NR elastomers were studied using moving die rheometer. The effect of vulcanization on styrene-NR elastomer containing natural rubber-graftpolystyrene was investigated in accelerated-sulphur curing system containing 2.0, 2.5, 3.0, 3.5 phr of sulphur with various temperatures ranging from 130 ?C to 160 ?C. Increase of tensile strength resulted from an increase of the crosslink density of vulcanization when compared to uncured sample. Furthermore, the accelerating action of temperature in curing system could be confirmed by increase of curing rate index and rate constant. The value of activation energy of the cure reaction could be calculated as 72.278 kJ/mol. |

The effect of process factors on tensile strength was investigated by varying the temperature, rubber-to-monomer ratio, and initiator and emulsifier contents from 50 to 64 ?C, 1.5 to 9, 0.8 to 1.4 g, and 4.5 to 6.5 g, respectively. Experimental results indicated that the tensile strength increased with an increase in reaction temperature, rubber to monomer ratio, and initiator and emulsifier contents. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Biosorption of Local Textile Dyes Onto Acid-Tolerant Macro-Beads of Chitosan-Immobilized Rhizopus arrhizus Biomass) ผู้เขียน:นางวีรานุช หลาง, ผู้ช่วยศาสตราจารย์, Pitchpong Buakaew, Wanvisa Buranaporipan, ดร.จินตนาถ วงศ์ชวลิต, ผู้ช่วยศาสตราจารย์, Nobuo Sakairi, ดร.วิรัตน์ วาณิชย์ศรีรัตนา, รองศาสตราจารย์, ดร.สาโรจน์ ศิริศันสนียกุล, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractIndustrial textile dye removal was investigated using dried fungal biomass (FB) and acid-tolerant chitosan-immobilized Rhizopus arrhizus biomass (Ch-F beads) to elucidate their potential application. The biosorption of two textile dyes, Cibacron Turquoise HGN (CT) and Remazol Red RGB (RR) was tested as dye models for phthalocyanine-based and azo-based reactive dyes. The surface charge density of Ch-F beads and FB was found to strongly accumulate both dyes under similar acidic (pH 3.0) conditions because of the synergy between the positive charges of the acidic pH and the anionic reactive dyes. The role of physicochemical properties related to their biosorption was described. Biosorption equilibrium was established within 30 min for the FB, but retarded for the Ch-F beads due to the densely packed fungal mycelia inside the beads. The diffusivity of RR and CT in the biosorbent was verified exploiting the proposed intraparticle diffusion model. According to the Langmuir model, the maximum dye uptake capacity of the Ch-F beads for RR and CT was 198.15 and 76.84 mg.g-1, respectively. The desorption of dye-loaded Ch-F was effective using 0.1 M NaOH. This indicated the desirable applicability of Ch-F beads for the treatment of wastewaters containing dyes. |
