HG/T 5066-2016水性涂料用分散劑

本標(biāo)準(zhǔn)規(guī)定了聚丙烯酸鹽等聚羧酸鹽及其改性聚合物分散劑的產(chǎn)品分類，要求，試驗(yàn)方法，檢驗(yàn)規(guī)則以及標(biāo)志、包裝和貯存。本標(biāo)準(zhǔn)適用于聚丙烯酸鹽等聚羧酸鹽及其改性物所合成的高分子聚合物類分散劑，該產(chǎn)品主要用于水性涂料中顏料和體質(zhì)顏料的分散和穩(wěn)定，也可用于色漿中顏料的分散和穩(wěn)定。本標(biāo)準(zhǔn)不適用于含有納米顏料和高色素炭黑的水性涂料和色漿用分散劑，也不適用于固體狀水性涂料用分散劑。

DIN ISO 14887-2010樣品制備.粉末在液體中的分散程序

This International Standard was developed to help particle size analysts make good dispersions from powder/liquid combinations with which they are not experienced. It provides procedures for - wetting a powder into a liquid; - deagglomerating the wetted clumps; - determining if solution composition can be adjusted to prevent reagglomeration; - selecting dispersing agents to prevent reagglomeration; - evaluating the stability of the dispersion against reagglomeration.
