PRODUCING METHOD FOR MONO-DISPERSED CROSS-LINKED CORPUSCLE OF LARGE-CALIBER BY MEMBRANE EMULSIFICATION TECHNIQUES

摘要

A kind of method, for producing monodisperse by using a kind of membrane emulsification methods, bigbore, the microshperes of crosslinking is configured to ensure that breaking strength and high compression recovery ratio. A kind of method, for producing monodisperse, it is bigbore, the microshperes of crosslinking be the perfomed by using membrane emulsification the following steps are included:: so that droplet by pressing is become the disperse phase liquid containing crosslinking agent, promoter and hydrophobic additive, dispersing agent and the water in continuous phase liquid containing surfactant by a porous membrane, small pore size having the same; It polymerize droplet. Monodisperse, it is bigbore, the blood cell of crosslinking with 10-100 micron average particle size, 10% or less particle size distribution a or more breaking strength and 60% of resultant yarn strand, 10gf or more compression recovery ratio.
