The investigation of a lot of parameters about treated sandstone, brick materials and earthen materials with fluorited polymers has been carried out, such as the formation of polymer, the penetration depth, porosity, capillary absorption and penetration coefficient, water uptake, compressive strength, drilling resistance, absorption isotherms of water vapor, water vapor diffusion, color changes as well as resistance to desegregation of water, frizzing - throwing cycles, worming - cooling cycles, and so on. in addition, the influence of salt crystallization, acid and base, and uv aging have also been assessed in order to better understand the protection effects and utilization possibility of two fluorinated polymers, mainly according to astm standard and the combination of international methods together with general technological
分別以國家級文物保護單位的土質、砂巖和磚材文物樣品為對象,依據astm標準及國際通用文物保護研究方法與評估準則相結合,通過膠化物形成周期、滲透深度、孔隙度、毛細吸水和滲透系數、持水量、抗壓強度、抗鉆強度、吸附水蒸氣的能力、透氣性、外觀顏色等系列參數的測定,及凍融、冷熱循環、酸堿腐蝕后抗壓強度的衰減、可溶鹽對保護效果的影響、酸堿及光照對表面保護效果的影響,對兩種含氟聚合物及其與有機硅的共混物在文物加固保護和表面防護中的可行性和保護效果給予了系統研究。Because of its specific structure and appropriate cation exchange capacity ( cec ), montmorillonite has been used in the preparation of polymer / layered silicate nanocomposites
由於蒙脫土( montmorillionite , mmt )具有特殊的結構和適中的離子交換容量,可用於制備聚合物/層狀硅酸鹽納米復合材料。Citric acid, taking the place of hno3, solutes the substance which does not solute in solution, and it acts as the ligand of metallic ionic and the hydrolysis catalyst of si ( oc2h5 ) 4, which reduces the pollution caused by no2 which forms at the decompose process of the hot treatment. by changing the means of calcine of the drier gel, choosing the suitable temperature to burn the gel, the high temperature calcine time is shorted, which solves the question of the long period calcine. so the preparation process of the matrix and composite was finished by using more lower temperature than the traditional solid state reaction and more shorter time than the traditional sol - gel process
結果使基質和復合物的制備在比傳統的固相反應法低得多的溫度下和比常規的溶膠凝膠法短得多的時間里完成;五、對基質及復合物的干凝膠、粉體和燒結體進行了ir 、 dta 、 xrd 、 seni及交流阻抗譜表徵,研究結果表明:在溶膠向凝膠的轉化過程中同時存在著正硅酸乙酯自身的聚合作用和檸檬酸鹽絡合物之間的聚合作用:干凝膠向產物粉體的轉化在400600c之間進行;基質li 。However, most of those flame retardants will reduce the other properties of materials at the same time. to overcome this drawback, a reactive flame retardant, which was incorporated in the main chain of pet, was used and an intercalative polymerization to layered silicates was conducted so as to prepare novel flame - retardant copolyesters / layered silicate nanocomposites
為了克服這一缺點,我們在引入一種反應型含磷阻燃劑的同時,通過插層聚合的方法合成了一種新型的聚合物材料:主鏈含磷阻燃共聚酯層狀硅酸鹽納米復合材料,以期在提高聚合物阻燃性的同時,亦改善材料的其它性能。The unstable stacking of layers of org - mmt was easily damaged under force and heat. hence, it is very important to decide the process temperature for preparing the composites, and it was found that 200 was a upper limitation of temperature
由於在高熱( 200以上)或強機械剪切作用下,蒙脫土層狀堆疊結構會坍塌,導致不能與聚合物分子作用生成聚合物?層狀硅酸鹽納米復合材料,因此熔融插層的溫度選擇顯得十分重要。Polymer melt intercalation is a promising new way to fabricate polymer layered - silicate nanocomposite by using conventional polymer melt blending technology. this method is simple and does n ' t need any solvents, so it is convenient to be put into production
熔融插層是應用傳統聚合物共混加工工藝制備聚合物基硅酸鹽粘土納米復合材料的一種新方法,這種方法不需要任何溶劑,工藝簡單,更易於工業化應用。The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper. the experimental results indicate that the effect of single retarder, such as citric acid, is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0. 5 ?, by weight ). the effect of different water - retention agents, such as polyvinyl alcohol ( pva ), carboxymethyl cellulose ( cmc ), and na - bentonite, etc., was also studied, and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved. the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other
