Study of influence of cross - linking agent preparation on property of pillared montmorillonite 鈦交聯(lián)蒙脫石納米復(fù)合材料的合成與物理性能
It has been studied that the effect of component , cross - linking agent pg and dvb and initiating agent bpo on mechanical properties of pu ( based polyether ) / ps ipns 研究了組成、交聯(lián)劑pg和dvb以及引發(fā)劑bpo對(duì)基于聚醚pu用s互穿網(wǎng)絡(luò)聚合物材料力學(xué)性能的影響。
But when the content of the cross - linking agent is 1 ~ 3 % , it is suitable . when its use level is too much , the performance of coating is greatly reduced because of too much cross linkage 但交聯(lián)劑有一合適的用量( 1 3 ) ,當(dāng)交聯(lián)劑用量過(guò)大時(shí),由于過(guò)度交聯(lián),反而使涂料性能明顯降低。
The investigation showed that nanofiltration membrane with good character can be made when concentration of coating solution is 1 % - 2 % , coating time is 1 hour , concentration of cross - linking agent is 0 . 5 % and cross - linking time is 5 hours 研究表明涂層液濃度在1 2 ,浸涂時(shí)間1h ,交聯(lián)劑濃度為0 . 5 ,交聯(lián)時(shí)間5h的條件下可以得到性能較好的納濾膜。
We selected styrene as monomer , diethylene glycol dimethacrylate as cross - linking agent . the copolymerization technique was used in preparing the probe . the ph fluorescent indicator was immobilized in the probe as the sensitive element 我們選擇苯乙烯為聚合單體,雙甲基丙烯酸一縮二乙二醇酯為交聯(lián)劑,采用交聯(lián)共聚技術(shù)制備氨多孔塑料傳感探頭,并將ph熒光指示劑固定于共聚體中作為氨的敏感元素。
