1、畢業(yè)設(shè)計(jì)(論文)題目:新型減水劑的合成及應(yīng)用學(xué)院:紡織與材料學(xué)院專業(yè)班級(jí):07級(jí)輕化工程(3)班指導(dǎo)教師:習(xí)智華職稱:副教授學(xué)生姓名:嚴(yán)斐雪學(xué)號(hào):40701030319摘要我國(guó)是世界上陶瓷生產(chǎn)量最大的國(guó)家,該行業(yè)在我國(guó)國(guó)民經(jīng)濟(jì)中占據(jù)了舉足輕重的地位。陶瓷行業(yè)是礦產(chǎn)資源消耗量大、能耗高、污染較大的行業(yè),在帶來(lái)巨大經(jīng)濟(jì)效益的同時(shí),也帶來(lái)嚴(yán)重的環(huán)境問(wèn)題。用優(yōu)良的減水劑,能保證陶瓷生產(chǎn)向高效益、高質(zhì)量、低耗能的方向發(fā)展。世界陶瓷生產(chǎn)發(fā)達(dá)國(guó)家十分注重減水劑的開(kāi)發(fā)和應(yīng)用,其中聚羧酸系高性能減水劑是2O世紀(jì)90年代之后興起的新一代減水劑。目前,國(guó)內(nèi)外對(duì)聚羧酸系減水劑的研究及應(yīng)用大都集中于混凝土建筑工
2、程領(lǐng)域,而對(duì)其在陶瓷領(lǐng)域中的研究則很少,因此,研究聚羧酸系陶瓷減水劑是目前陶瓷領(lǐng)域的一個(gè)重要課題。聚羧酸系高性能減水劑是目前世界上最前沿、科技含量最高、應(yīng)用前景最好、綜合性能最優(yōu)的一種高效減水劑。聚羧酸系減水劑通常由含羧酸基和聚氧化乙烯基的乙烯基在聚合物的分子結(jié)構(gòu)中,不同單體以隨機(jī)或有規(guī)律地聚合在一起,因此聚羧酸系聚合物結(jié)構(gòu)和性能具有多變性,它的作用和它的分子量有密切的關(guān)系。低分子量的聚丙烯酸鈉的用途極為廣泛,可作為水質(zhì)穩(wěn)定劑、陶瓷添加劑、顏料分散劑、水泥減水劑等。通過(guò)聚丙烯酸鈉的研究,希望可以對(duì)國(guó)內(nèi)的建陶業(yè)的生產(chǎn)成本、生產(chǎn)效率有所推動(dòng)。在當(dāng)前可持續(xù)發(fā)展的大力倡導(dǎo)、激烈的競(jìng)爭(zhēng)下,更值得
