Effects of urea formaldehyde resin to film properties of alkyd–melamine formaldehyde resins containing organo clay

Organo clay modified alkyd resins were prepared and these modified alkyd resins were cured with different ratios of melamine formaldehyde and urea formaldehyde resins in this work. Alkyds formulated to have oil content 40% were prepared with phthalic anhydride (PA), glycerine (G), coconut oil fatty acid (COFA), dipropylene glycol (DPG) and organo clay. “K alkyd constant system” was used for the formulation calculations of the alkyd resins. Alkyd resins were blended with 40% of a commercial melamine formaldehyde. The films of the alkyd–amino resins were prepared from 60% solid content xylene solutions using 50 μm applicators. After the films were cured at 140 °C for 2 h in an oven, properties of the films were determined. The film properties of the alkyd–amino resins such as drying degree, hardness, adhesion strength, abrasion resistance, water, acid, alkaline, solvent resistance, and resistance to environmental conditions were investigated. The addition of the urea formaldehyde resin and organo clay has positive effect on the physical and chemical resistance of the alkyd–amino resins.

INTRAPARTICLE MASS TRANSFER IN THERMALLY REGENERABLE ION EXCHANGER

An intraparticle mass transfer model was developed for a thermally regenerable ion exchanger which is coagulated by weak acidic and basic microspheres. It was assumed that salt diffuses (hrough macropore and microspheres in the radial direction of a resin particle. Uptake curves were measured not only in [R_aCOOH + R_bN] + NaCl ) [R_aCOONa + R_bNHCl] system but also in [R_aCOO²²Na⁺ + R_aN] + Na⁺ )[R_aCOONa⁺ + R_bN] + ²²Na⁺ and [R_aCOOH + R_aN] + HCl ) [R_aCOOH + R_bNHCl] systems. Macropore diffusivity D_p.Na, tortuosity factor τ_p and diffusivity through weak acidic microspheres D_a,Na were obtained from the isotopic ion exchange. The uptake curves of HC1 gave diffusivity through weak basic microspheres.D_b,Hcl The experimental uptake and desorption curves of NaCl agreed fairly well with the theoretical values. Diffusions through both macropore and microspheres were significant. The diffusivity through microspheres D_b,Nacl NaCI are smaller than D_a,Na. and can be estimated by D_bHcl approximately.
