聚丙烯酰胺(PAM)和部分水解聚丙烯酰胺(HPAM)在蒙脱土、高岭土、磷灰石上的吸附已有报道,但在海泡石上的吸附尚未见报道.海泡石不同于上述粘土,它属于纤维棒石粘土矿物,所形成的悬浮体呈棒状单元的干草堆状结构,很容易在盐水中分散形成稳定的悬浮体.在地热钻井和海洋石油钻井中有广泛应用.本文参照 Hollander 等人的方法,研究了 HPAM 在海泡石上的吸附和各种因素对吸附的影响,并从 HPAM 分子的形态和固体表面性质出发,对这些结果进行了讨论.
Adsorption of polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) on montmorillonite, kaolin and apatite has been reported, but adsorption on sepiolite has not been reported yet. Sepiolite is different from the clay , Which belongs to the fibrillarite clay minerals, the formed suspension is a haystack-like structure with rod-shaped units and is easy to disperse in brine to form a stable suspension, which is widely used in geothermal drilling and offshore oil drilling.In this paper, Hollander Et al., Studied the adsorption of HPAM on sepiolite and the influence of various factors on the adsorption. Based on the morphology and solid surface properties of HPAM molecules, these results were discussed.
