摘要： A method for manufacturing a modified porous composite structure includes steps as follows. A functionalized melamine sponge is provided, a porous organic framework source is provided, a connecting step is conducted, and a modifying step is conducted. The porous organic framework source includes a porous organic framework or a precursor of the porous organic framework. The porous organic framework and the precursor of the porous organic framework include a plurality of first ligands. Each first ligand includes at least one tetrazine group. In the connecting step, the functionalized melamine sponge is combined with the porous organic framework, so that a porous composite structure is obtained. In the modifying step, a reactive group of a modifying group donor is reacted with the tetrazine group, so that a modifying group of the modifying group donor is connected to the porous composite structure to obtain the modified porous composite structure.

摘要： The present invention generally relates to a process for reducing formaldehyde content from cationic melamine-formaldehyde resin solution. Said process comprises the steps consisting of charging a starting solution to an ultrafiltration membrane system, separating said starting solution into a concentrate solution which mainly comprises cationic melamine-formaldehyde resin of high molecular weight, formaldehyde and water, and a permeate solution which mainly comprises cationic melamine-formaldehyde resin molecules of low molecular weight, formaldehyde, acid compounds and water and treating the permeate solution to reduce the free formaldehyde content of the permeate.

摘要： Methods for producing microcapsules begin by preparing an emulsion of a surfactant, core material, and water, followed by the addition of a crosslinking agent and a melamine formaldehyde prepolymer, which is subsequently polymerized. The crosslinking agent is added before the melamine formaldehyde prepolymer, with a first addition or a second addition of a melamine formaldehyde prepolymer, or is divided for addition with both a first addition and a second addition of melamine formaldehyde prepolymer. The crosslinking agent is a mixture of a reaction product of a cyclic urea (U) and a multifunctional aldehyde (A), and at least one crosslinker selected from the following group: a reaction products of (i) an aminotriazine and at least one aldehyde selected from the group consisting of aliphatic monoaldehydes and multifunctional aliphatic aldehydes, (ii) urea and/or cyclic ureas and formaldehyde, or (iii) phenols and aliphatic monoaldehydes, or from alkoxycarbonylaminotriazines, or multifunctional isocyanates, epoxides, aziridines, and carbodiimides.
