Production of Melamine-Formaldehyde PCM Microcapsules with Ammonia Scavenger used for Residual Formaldehyde Reduction.
Paraffinic phase change materials (PCM) were microencapsulated by in situ polymerization of melamine-formaldehyde prepolymers. Partly methylated trimethylolmelamine was used as an aminoaldehyde prepolymer for the microcapsule wall, a styrene-maleic acid anhydride copolymer as an emulsifier and modifying agent, and ammonia as a scavenger for reducing residual formaldehyde. For the determination ...
متن کاملResidual stress evaluation in resin - molded
The high residual stress in a resin-molded electronic package sometimes makes the electronic functions unstable. Therefore the residual stress in electronic packages, especially on the top surfaces of semiconductor chips, should be evaluated. The objective of this study is to present a simple method for evaluating residual stress in resin-molded semiconductor chips using a combination of experi...
متن کاملFormaldehyde and Ammonia as Precursors
Fig. 3. Inhibition of binding of ['4C]pentobarbital to rabbit antiserum by nonradioactive pentobarbital in buffered saline (0 0 *), plasma (0 O), or urine (X X). Incubation medium consisted of 0.10 ml of normal rabbit serum, 0.10 nml of rabbit antiserum (0.4 mg of protein), 0.01 ml of ['4C]pentobarbital (O.1 nmole), and 0.01 ml of either standard unlabeled pentobarbital (1 to 100 ng) or unknown...
متن کاملSynthesis of Humin-Phenol-Formaldehyde Adhesive
Humins are low-value-added byproducts from the biomass acid hydrolysis process. In the present work, humins were first employed as a phenol replacement for synthesis of modified phenol-formaldehyde adhesives through a two-step process. In this process, humins were first utilized to obtain alkaline soluble products, mainly consisting of phenolics, through a hydrothermal process. The obtained alk...
متن کاملPreparation and characterization of carbon materials from phenol formaldehyde resin with pore forming substance
This paper describes the carbonization behavior of phenol-formaldehyde resin (PF) blended in the presence of simple organic substances of m-phthalic acid (PA), trimesic acid (TMA) and phloroglucinol (PG). The weight loss and heat flow were monitored in order to study their carbonization behavior by thermogravimetric analysis (TG) and differential scanning calorimetry (DSC), respectively. These ...
