含 has material and filler and other solid pellets liquid system can can 会出现一 issues. its in types defect phenomenon is 絮凝, liquid in solid pellets viscous in 一起.

絮凝 is pellets between 始终存 in force 引起, anti 止絮凝 principle is ensure pellets versus 互排斥, force must large 于吸引 force, remove 空间位 retardant dispersant stability mechanism outer, electrical stability can used as mechanism.

当 system in has pellets belt/tape has same 符号 静 electrical 荷时, electrical stability can anti 止絮凝, pellets upper electrical amount must 足以抵消吸引 force. in large more coating material and ink in, pellets belt/tape has negative electrical 荷, this type of type type stability is anionic stability, most used for water system.

solid pellets can belt/tape electrical, in large more 数情况 lower, product development usually use in pellets surface belt/tape electrical polymer ensure has pellets tool has same electrical 荷, provide stability function anti 止絮凝 polymer additives is electrical stability dispersant. electrical dispersant separation must tool has types 基团才 can provide electrical stability property. 首先, 锚定基团必 must ensure separation 子吸附 in pellets surface; its 次, dispersant separation must belt/tape negative electrical 荷 基团. use combined this standards dispersant 时, by liquid 体包围 solid pellets will obtain negative electrical 荷.

当 use electrical as is stability mechanism 时, formulation must maintain 警惕, causes is through electrical achieve stability for PH value can can very 敏感: pellets （ dispersant separation 子） electrical 荷取决于PH value. in addition, belt/tape electrical pellets force 也取决于 salt in effect/influence, pellets liquid in in 离子时, belt/tape electrical pellets between versus 互排斥 force more 糟, this is is 当离子添 add to liquid in 时, pellets belt/tape electrical 层（即 谓 electrical di 层）会 shrinkage. electrical di must tool has most small thick degree, ensure 足够 排斥 force.

through ensure pellets between force strong/high 于吸引 force, can has anti liquid system in solid pellets 发生絮凝. electrical stability is types commonly used methods, through make pellets belt/tape same 符号 静 electrical achieve. however, design in use electrical as is stability mechanism must attention/notes system PH value and 离子 存 in, ensure force has property. through combined selection and use dispersant, can in water system in achieve good stability property.
