AKD是什么東西
烷基烯酮二聚物 (Alkyl Ketene dimers) 是造紙較常用的一種合成膠。結(jié)構(gòu)式如下。 RCH=C一CHR'
丨 丨
O一C=O
結(jié)構(gòu)式中的R或R'為烷基,變更不同的烷基可以得到一系列的烷基烯酮二聚體,但適于造紙中性施膠的是14烷和16烷。
AKD乳液的物理指標(biāo):
外 觀: 白色乳狀液...............外觀: 白色乳狀液
固含量: 15%................... . 固含量: 10%

粘 度: <20 cps (25°C)........粘度: <10 cps (25°C)
PH 值: 2-4 ..................... PH 值: 2-4

AKD發(fā)展歷史:
1948年,美國Herecules公司發(fā)明了一種中性施膠劑---烷基烯酮二聚體(Alkyl Ketene dimer)。但當(dāng)時由于乳液穩(wěn)定性差,陽離子淀粉和助留劑等化學(xué)品尚未發(fā)明,膠料留著率低,因而未能廣泛應(yīng)用。到1972年之后才有所改善,之后質(zhì)量不斷提高。
編輯本段AKD使用:
固體AKD的熔點約50℃,不溶于水,制膠時需加入分散劑和乳化劑(如陽離子淀粉)。 AKD適用于在pH值為8.2的條件下使用。一般在上網(wǎng)前加入。,主要用于造紙中性施膠 AKD的施膠作用在紙頁干燥以后尚未完成,卷取后存放24小時僅完成80%,若干天后施膠反應(yīng)還在繼續(xù)進(jìn)行。
AKD主要適用的紙種:
施膠要求比較高的紙種:靜電復(fù)印紙、無碳復(fù)寫紙、水松原紙、彩色噴墨紙、照相原紙、雙面膠版紙、液體食品包裝紙、水果袋紙、紙杯紙、白卡紙、防貼原紙、不干膠帶紙。
施膠要求較一般的紙種:書寫紙、課本紙、轉(zhuǎn)移印花紙、膠印新聞紙、
單膠紙、銅板原紙、白面牛皮卡紙、紗管原紙、膠印涂布紙、打字紙、有光紙、瓦楞原紙。
yl在化學(xué)里什么意思
你好,如果我沒有猜錯的話,這個應(yīng)該是你在化學(xué)的英文術(shù)語中看到的。
yl是X基的英文后綴。我們都知道
甲基是methyl 分解meth+yl meth:甲或一的意思
乙基是ethyl 分解 eth+yl eth:乙或二的意思
丙基是propyl 分解 prop+yl prop:丙或三的意思
苯基是phenyl 分解 phen+yl phen:苯的意思
烷基是alkyl 分解 alk+yl aik:烷烴的意思
我們很明顯看出yl都是這些基團(tuán)的后綴,yl可以簡單理解成就是漢語里的基的意思。
