1、色相變化：將未固色處理的染色物與固色處理的織物用變褪色灰色樣卡進行評級，并以未固色處理的織物為基準，注明色調的變化。用電腦測配色測色，以未固色的染色織物為標樣，固色織物為仿樣，測出固色織物的色光變...

1. Hue change: The unfixed dyed matter and the fixed color treated fabric are rated with a faded gray sample card, and the unfixed fabric is used as the benchmark to indicate the change of color tone. Use compu...

吸附脫色劑在油脂精煉中的研究概況Research situation of adsorption decolorant in oil refining

在食用油脫色工藝中，根據脫色原理可以將脫色劑分為三大類：絮凝脫色劑、氧化脫色劑和吸附脫色劑；絮凝脫色劑是一種具有脫色、絮凝等多種功能的季胺型陽離子聚合物[1]；吸附脫色劑一般為活性白土、凹凸棒土、活性...

In the edible oil decolorization process, decolorizers can be divided into three categories according to the decolorization principle: flocculation decolorizers, oxidative decolorizers and adsorption decolorize...

通常雖然有些染料可以染出比較鮮艷的色澤，并且直接染料、酸性染料等陰離子水溶性染料色譜，但由于染料上帶有水溶性基團，使得濕處理牢度不好，褪色和沾色現象嚴重。不僅使紡織品本身外觀陳舊，同時染料脫落下來會沾...

Usually, although some dyes can be dyed with brighter colors, and anionic water-soluble dyes such as direct dyes and acid dyes are chromatographic, but because of the water-soluble groups on the dyes, the fastn...

1、二氧化碳濃度增加這類廢水在印染、防染鹽類廢水中較為常見，由于加入的藥劑是有機的，在水中的殘留物過多后會出現 COD，所以一般用陽離子季銨鹽進行脫色。2、氨或總氮含量增加這一般跟 COD是同步發生的...

1. This type of waste water is more common in printing and dyeing and anti-dyeing salt waste water due to the increase in carbon dioxide concentration. Since the added agent is organic, COD will appear when the...

絮凝劑和反絮凝劑的區別是什么What is the difference between flocculants and deflocculants

2022-02-17

絮凝劑和反絮凝劑所用的電解質相同，只是加的量不同，少量時每個離子能夠將多個反電荷的粒子吸附到一起或者降低ξ電位，從而發生絮凝作用；加大到足夠量，多個離子由于靜電吸附包圍一個反電荷粒子，使ξ電位增加，起...

The electrolytes used in flocculants and deflocculants are the same, but the amount added is different. When a small amount is used, each ion can adsorb multiple counter-charged particles together or reduce the...
