Acrylic binders for ceramics.

The synthesized binders are characterized by low glass transition temperatures 5 6 c and 0 5 c which are much lower than that of pva 42 c. The green bodies 30 30 3 mm were prepared on the injection molding machine jph30 guangdong only machinery co ltd. Acrylic binders for dry pressing ceramics. Silicon nitride granule friction measurements with an atomic force microscope.

Then ceramic feedstocks were broken to 3 5 mm. The results confirmed that the synthesized binder is eco friendly because it decomposed to non toxic gases such as carbon dioxide and water vapor during heating up to ca. Ceramic powders and the binders listed in table 1 were mixed on the double roller for 40 50 min at 140 150 c and the ceramic feedstocks were obtained. Binders for ceramic products are provided which are crosslinkable and impart improved tensile strength to ceramic green bodies.

Advanced ceramics like high purity aluminium oxide lee et al 2003 medvedovski 2001 with acrylic binders are increasingly being used in many engineering applications where high wear resistance. Effect of humidity and binder concentration powder technology 10 1016 s0032 5910 01 00260 1. 2 studied the strength of ceramic green bodies with respect to the glass transition temperature of polymeric binders from which they suggested that the acrylic binder was. It has been found that the acrylic co polymers of mma with ma 70 30 and with eha mma and maa 55 43 2 are good binders for the dry pressing of the ceramic materials.

These types of polymers can be tailor made to suit to the end application.
