The results showed that the structure of St-g-PAM was meshy,and porous,and integrant linetype,the soluble starch had elliptic form,and PAM was linear color;the crystallinity of St-g-Pam had been improved,and was better than PAM;the thermal stability of St-g-PAM was also better than PAM,which was the significant reason that the graft polymer had the ability of excellent flocculation.

線型St-g-PAM作為一種新型的高分子絮凝劑，它結(jié)合了淀粉與聚丙烯酰胺的特性欧美激欧美啪啪片动态图，廣泛應(yīng)用于廢水處理黑人大战白妞系列AV、石油化工一级片操逼视频、造紙工業(yè)等領(lǐng)域[3~5]。由于其原料淀粉來(lái)源豐富午夜欧美一区二区、價(jià)格低廉99riAV.cn，且線型St-g-PAM的成本比PAM低，故越來(lái)越受到人們的重視麻豆国产原创视频在线。

Methylol polyacrylamide was first formed by the reaction of PAm with F in basic medium, then the cationic polyacrylamide was formed by the further reaction of PAm·M with D.

合成反應(yīng)通過兩步進(jìn)行变态自拍日韩欧美在线观看网站视频，先使PAm與F反應(yīng)，生成羥甲基化產(chǎn)物PAm·M亚洲一级这片，然后在酸性條件下使PAm·M與D反應(yīng)日韩性插，制得PAm·MG。

Compared with no used Wote super absorbent and PAM in loess hilly and gully regions of northern Shaanxi, applying Wote super absorbent and PAM in small holes near seed potato and soaking seed potato with 1.0% Wote super absorbent and 1.0% PAM, the effects of Wote and PAM on soil moisture and growth of potato were researched.
