前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

本文件是GB/T44626《微細(xì)氣泡技術(shù)表征用樣品中氣泡消除方法》的第1部分，

GB/T44626已經(jīng)發(fā)布了以下部分：

—第1部分：評(píng)估程序。

本文件修改采用ISO24261?1：2020《微細(xì)氣泡技術(shù)表征用樣品中氣泡消除方法第1部分：評(píng)

估程序》。

本文件與ISO24261?1：2020相比做了下述結(jié)構(gòu)調(diào)整：

—7.1對(duì)應(yīng)ISO24261?1：2020中7.2；

—7.2對(duì)應(yīng)ISO24261?1：2020中7.1。

本文件與ISO24261?1：2020的技術(shù)差異及其原因如下：

—用規(guī)范性引用的GB/T41914.1替換了ISO20480?1（見(jiàn)第3章），以適應(yīng)我國(guó)的技術(shù)條件，提高

可操作性；

—增加了術(shù)語(yǔ)“體積濃度”與“體積濃度指數(shù)”（見(jiàn)3.3、3.4），以提高可操作性；

—增加了“f）本文件編號(hào)”（見(jiàn)第7章）,以提高可操作性。

本文件做了下列編輯性改動(dòng)：

—用資料性引用的GB/T42843.1—2023替換了ISO20298?1：2018（見(jiàn)3.2），用GB/T6682替

換了ISO3696（見(jiàn)4.1），用GB/Z44387—2024替換了ISO/TR23015：2020（見(jiàn)4.2），用

GB/T25915.1替換了ISO14644?1（見(jiàn)第5章）；

—將全文中的“消除效率”更改為“消除率”；

—將圖A.1、圖A.2的單位“million/mL”更改為“×106個(gè)/mL”。

GB/T44626.1—2024

引言

微細(xì)氣泡技術(shù)近年來(lái)在清潔、水質(zhì)處理、農(nóng)林牧漁以及生物醫(yī)療等領(lǐng)域均取得了長(zhǎng)足發(fā)展。目前，

缺乏有關(guān)微細(xì)氣泡發(fā)生系統(tǒng)效果的評(píng)估方法與規(guī)范，特別是對(duì)微細(xì)氣泡的數(shù)量濃度指數(shù)和粒徑指數(shù)等關(guān)

鍵參數(shù)指標(biāo)的評(píng)估。此外，微細(xì)氣泡分散液可能含有其他固體顆粒和液滴。顯然，考慮到這些因素的影

響，不太可能直接使用顆粒檢測(cè)方法評(píng)估微細(xì)氣泡的特性。因此，如何消除這些因素的干擾，已成為一

項(xiàng)迫切需要解決的問(wèn)題。

雖存在多種顆粒數(shù)量濃度指數(shù)與粒徑指數(shù)的檢測(cè)方法，但能有效區(qū)分微細(xì)氣泡分散液中的氣泡與其

他顆粒的手段相對(duì)較少。一種有效的解決方法是通過(guò)溶解及浮升消除氣泡。如果存在一種能消除特定粒

徑范圍微細(xì)氣泡的技術(shù)，便能有效地將微細(xì)氣泡與其他的固體顆粒與液滴區(qū)分開(kāi)來(lái)，這樣才可能有針對(duì)

性地消除微細(xì)氣泡。當(dāng)絕大部分微細(xì)氣泡被消減時(shí)，無(wú)氣泡的溶液則可視為空白溶液用作測(cè)量背景。隨

著微細(xì)氣泡消除技術(shù)的持續(xù)進(jìn)步，發(fā)展標(biāo)準(zhǔn)化的氣泡消除技術(shù)及相應(yīng)評(píng)估方法是非常必要的。

GB/T44626《微細(xì)氣泡技術(shù)表征用樣品中氣泡消除方法》旨在對(duì)微細(xì)氣泡分散液中微細(xì)氣泡消

除率的評(píng)估方法進(jìn)行規(guī)范與標(biāo)準(zhǔn)化，擬由兩個(gè)部分構(gòu)成。

—第1部分：評(píng)估程序。目的在于對(duì)微細(xì)氣泡分散液中微細(xì)氣泡消除程序規(guī)范化、消除率評(píng)估標(biāo)

準(zhǔn)化。

—第2部分：微細(xì)氣泡消除技術(shù)。目的在于規(guī)定消除微細(xì)氣泡分散液中微細(xì)氣泡的方法及相應(yīng)的

操作規(guī)程。

通過(guò)微細(xì)氣泡消除率的標(biāo)準(zhǔn)化，能簡(jiǎn)單、明確地比較幾種消泡技術(shù)的優(yōu)劣，進(jìn)而實(shí)現(xiàn)各自氣泡消除

技術(shù)條件下的優(yōu)化。
