泳透力阴极电泳涂装的泳透力就是在电场的作用下,电泳漆对被涂物背离阳极的部位(工件内腔、凹面、缝隙等处)的涂覆能力。也就是说使结构形状复杂的工件全部表面均匀的涂上漆膜的能力。泳透力的高低影响着复杂工件表面的防腐性。
阴极电泳涂装时,电沉积是沿着存在于阴极和阳极之间的电力线进行的,沉积行为是沿“阻力”*小的路线进行的,优先涂覆在*靠近阳极的阴极工件外表面,随着沉积膜厚的增加,所形成的涂层的绝缘特性渐渐屏蔽了工件的导电性,并使在此沉积部位的电场强度因出现这种绝缘现象而减小,电力线转移到较远的工件表面,随着沉积的进行,外表面便完全绝缘,电沉积停止,电力线将开始完全作用于工件内表面。同样,重复上述的过程而使被涂物的内、外表面均匀被涂上漆膜。
电沉积工作液的电导率越高,湿膜阻抗越大,其泳透力越高。泳透力还与涂装工艺参数直接相关,如泳涂时间长、电压和固体份高,泳透力也就会相应增高,它是确保工件内腔部分等。
The Anion exchange resins (AERs) are IERs that can exchange anions such as Cl- and SO42- and are classified into two groups; one is the group of the strongly basic anion exchange resins (SBAERs) and the other is of the weakly basic anion exchange resins (WBAERs).
The resins with quaternary ammonium groups (N+) as their functional groups, such resins dissociate and show as strong basicity as inorganic bases like NaOH or KOH. They are called as the strongly basic anion exchange resin.
The quaternary ammonium groups (N+), active groups in these resins, are strongly basic and they dissociate not only in acidic solutions but also in alkaline solutions to N + OH- form. SBAERs can exchange their counter ions even with neutral salts as with inorganic acids, as shown in Equations I-2-8 and I-2-9. They can exchange anions with weak acids such as silicic acids and carbonic acids. Thus the SBAERs are ion-exchangeable in all pH range.
· R-N·OH+NaCl-N·Cl→R+ NaOH (I-2-8)
· R-N·OH+HCl -N·Cl→R+ H2O (I-2-9)
The SBAERs are usually regenerated with 4% NaOH aqueous solutions. Weakly basic NH4OH can hardly regenerate SBAERs.
Eq.I-2-10 shows the regeneration reaction of Cl-form SBAER.
· R-N·Cl+NaOH-N·OH→R + NaCl (I-2-10)
Since the SBAER is strongly basic, it needs much more regenerants than the theoretical amount to regenerate SBAERs as same as the SACERs.
There are two types of SBAERs; type I has trimethylammonium groups, R-N+(CH3)3 , as ion exchange groups and type II has dimethylethanolammonium groups, R-N+(CH3)2·CH2CH2OH.
Both types I and II are strongly basic, type II is slightly weak in basicity and thus somewhat easy to be regenerated.
DIAION? SA10A and SA20A, the typical products of estTypebasicityI. SBCERs,Theycanadsorbareanionsthe high strongly. So they are used for making high-grade demineralized water. But it needs much regenerants because of the
strength of their adsorbability. The type II of the SBCERs are slightly weaker in basicity than the type I. So the quality of demineralized water made by them is inferior compared with the type I, but for that reason we can reduce regenerants
