Evaluating effects to parlygorskite organising modification by x - ray , tem , sem , ir , viscidity analysis etc . contrasting organising modification effects of parlygorskite original ore and acidified palygorskite , the result shows wd - 51 modification agent has better modification effect to acidified pargorskite than parlygorskite original ore 對比了用wd - 51對坡縷石原礦和酸化坡縷石進行有機化改性處理的改性效果,表明wd - 51對酸化坡縷石的改性效果要好。
The article is focused on the modification studies of chitosan ultrafiltrating compound membrane ( cs compound membrane ) on the basis of preceding researches . it includes adding cross - linking agent , modification agent , acylation agent in the casting membrane solution . the result shows that the new modification membrane are better in the phychemical properties and separation properties 本文是在前面研究的基礎上,著重進行了聚氨基葡糖復合超濾膜(簡稱cs復合膜)的改性研究.通過從交聯(lián)劑、改性劑、乙?;噭┑确矫娴母男詠韺で笞罴训蔫T膜液配方.結(jié)果表明,改性后的膜能達到較好的物化性能和分離性能
The purity and composition uniformity were very high , and the specific surface area was 67 - 156 nm . in the third part , surface modification of sn - in2o3 nano particle was studied and some conclusions were drawn finally . kh560 and kh570 were selected as surface modification agents , and the concentration of them was 0 . 5 - 1 wt % , and ph value was controlled for 5 . 4 , and the best milled technology were 72 hours 本文第三部分,結(jié)合丙烯酸酷類單體,對sn一inz仇納米微粒進行表面修飾研究,最后得出選用kh一560和kh一570作表面修飾劑,添加量為0 . 5一lwt %左右, ph值為5 . 4左右,采用球磨72小時,輔助超聲分散工藝時, sn一in20 :納米粉的分散性較好,且與基體有較好的相容性。
