style="text-indent:25px">如何選擇一種合適的氟碳表面活性劑產(chǎn)品？1，上海YM-319含氟表面活性劑、需要明確利用氟碳表面活性劑來提高配方中哪方面性能，是潤濕性，上海YM-319含氟表面活性劑、流平性還是發(fā)泡性或還是利用其高穩(wěn)定性來應(yīng)用到特殊環(huán)境中。2、考慮氟碳表面活性劑特別是其中非氟官能團是否與體系相容，是否會與體系反應(yīng)而破壞體系的穩(wěn)定性；或因其它副作用而影響較終產(chǎn)品的性能。3、考慮氟碳表面活性劑的物理性質(zhì)如溶解度、顏色、狀態(tài)是否會限制其在特定體系中的應(yīng)用。4、使用效果是否非常明顯，成本是否可行，上海YM-319含氟表面活性劑。氟碳表面活性劑水溶液的表面張力卻能降低至20 m N/m, 甚至達到15 m N/m。上海YM-319含氟表面活性劑</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海YM-319含氟表面活性劑,氟碳表面活性劑"

style="text-indent:25px">氟元素是電負性較強的元素，它具有高氧化勢、高電離能，這種特性一方面造成氟—碳鍵（F—C）鍵能高（實際上氟—碳鍵是已知鍵能較高的共價鍵），因而氟碳鏈結(jié)構(gòu)遠比碳氫結(jié)構(gòu)穩(wěn)定；另一方面氟原子非常難以被極化，使氟碳鏈極性比碳氫鏈小。正是因為這種低極性，使氟碳鏈疏水作用遠比碳氫鏈強烈（其實，低極性不但使氟碳鏈疏水，而且還疏油—這里油是指碳氫類化合物）；另外，低極性又導(dǎo)致氟碳鏈相互間作用力弱。這二個因素共同作用使得氟碳表面活性劑分子在水溶液中有比其它表面活性劑分子更加強烈的傾向來脫離水溶液，在液/氣界面上定向聚集排列成分子膜，從而使其具有與其它表面活性劑所不同的特性在極低應(yīng)用濃度下便能明顯降低水溶液的表面張力。天津YM-217界面活性劑表面活性劑中的非極性基不僅有疏水性質(zhì)而且獨具疏油的性能。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海YM-319含氟表面活性劑,氟碳表面活性劑" src="https://tyunfile.71360.com/UploadFile/shymhg/637393192762572398/4878611.png"></div><p style="text-indent:25px">涂料用氟碳表面活性劑YM-313的特點：1、添加量極小，成本低，配方中只需要添加0.1%~0.3%即能體現(xiàn)出良好效果，更可以減少其他潤濕劑，消泡劑的使用，有效降低成本。2、明顯改善潤濕性：大幅降低涂料體系的表面張力，提高涂料對底材的潤濕性和流平性，特別適合水性木器漆，水性塑料漆等材質(zhì)中使用；3、顏料分散性：改善顏料在涂料體系中的分散效果，更提高涂料的儲存穩(wěn)定性；4、復(fù)配性好：在水性涂料中添加，與多數(shù)其他助劑可以有效相溶，不會破壞原先涂料體。</p><p style="text-indent:25px">與普通表面活性劑一樣，氟碳表面活性劑的分類依據(jù)其極性基團結(jié)構(gòu)不同可分為非離子型和離子型二大類。非離子型的親水基一般為聚氧乙烯醚類的產(chǎn)品，易溶于水、有機溶劑（包括酸、堿介質(zhì)），與其它類型活性劑的相容性也更好。由于在水中不電離，故對pH值穩(wěn)定性高，但是要避免在強氧化介質(zhì)中使用，以免造成醚鍵斷裂。非離子型的氟碳表面活性劑也是在水性涂料中應(yīng)用較為普遍的一類。離子型氟碳表面活性劑根據(jù)親水基的不同又可分為陰離子型、陽離子型和兩性離子型氟碳表面活性劑。氟碳表面活性劑YM-313在水性涂料中添加，與多數(shù)其他助劑可以有效相溶，不會破壞原先涂料體。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海YM-319含氟表面活性劑,氟碳表面活性劑"

style="text-indent:25px">有些氟碳表面活性劑，在50~100ppm時便可將水溶液表面張力降到18～20dyn/cm。這主要是氟碳鏈疏水作用強烈，相互間分子作用力弱的原因。極高的表面活性，即可將水溶液表面張力降到極低水平。像全氟羧酸可以使水溶液表面張力降至15～16dyn/cm。這是因為氟碳表面活性劑中的氟碳鏈在水溶液表面形成排列整齊的單分子膜，就像在溶液表面鋪了一層氟碳化合物，而氟碳化合物是典型的低表面能材料，如聚四氟乙烯表面能為19dyn/cm。由于其分子中有兩個親水頭基,使得其溶解度相對較大,但同時也使得其降低水溶液表面張力的效率有所降低。氟碳表面活性劑的毒性比烴類表面活性劑小。上海YM-319含氟表面活性劑</p><p style="text-indent:25px">YM系列氟碳表面活性劑對地層傷害小，在高溫、酸性、礦化度高的惡劣環(huán)境下性能穩(wěn)定。上海YM-319含氟表面活性劑</p><p style="text-indent:25px">氟碳表面活性劑作為顏料分散劑,能提高顏料的分散性和載色體的均勻性,可防止顏料結(jié)塊,并使顏色更加鮮艷;同時,氟碳表面活性劑在皮革涂飾中也作為流平劑,使涂飾后成膜平整光滑,有助于提高涂飾層質(zhì)量。根據(jù)“相似相溶”原理,氟碳表面活性劑作為合成含氟聚丙烯酸酯類涂飾劑過程中的乳化劑使用時,可提高含氟單體的轉(zhuǎn)化率,且制備得到的含氟乳液的穩(wěn)定性較好。由于氟碳表面活性劑具有高表面活性、高化學(xué)穩(wěn)定性和高耐熱穩(wěn)定性及氟碳鏈既憎水又憎油的特性,將氟碳表面活性劑用于皮革加脂、涂飾等工序中,能賦予皮革特殊的性能,明顯提高皮革的檔次。上海YM-319含氟表面活性劑</p><p
