| 1. | Water inside the pvb freezes from the outside - inward 这种压力真空断路阀内部水是从外部往里冰冻的。 |
| 2. | Pvb films are stored near to bending furnace ( high temperature ) Pvb胶片存放在热弯炉旁边(温度太高) 。 |
| 3. | 4 10 , 000t y pvb plant 4年产1万吨pvb生产装置 |
| 4. | It is applicable to use en glue , paper , weaving material ( such as silk , cloth , nylon ) , pvb etc 适用于en胶片、纸质、纺织品(丝绸、布、尼龙)各种装饰、干法夹胶玻璃。 |
| 5. | Nano - zns : mn2 + dispersed in pvb film has the same enhancement after exposure in solar light . the material has potential on measuring the dosage of uv irradiation of solar light 薄膜样品在太阳光辐照下同样有荧光增强行为,预示该样品可以作为一种紫外辐照剂量的记录材料。 |
| 6. | Meanwhile , the pervaporation of pvb membrane containing etherified p - cd and ca membrane containing etherified p - cd were measured respectively , obtaining a permeation flux greater than other membranes with p - cd 同时,测试了醚化- cd与聚乙烯醇缩丁醛( pvb )共混膜,醚化- cd与ca共混膜的渗透汽化性能,获得了比较理想的渗透通量。 |
| 7. | In this paper , polyvinyl - butyral ( pvb ) and methyl cellulose ( mc ) are chosen as chemical additives to amend the property of normal mortar , orthogonal tests of 96 pieces of shear specimens are carried out , then orthogonal analysis of test results is performed 采用聚乙烯醇缩丁醛和甲基纤维素对普通砂浆做合理改性,进行了96个抗剪试件的正交试验,并对试验结果进行正交分析。 |
| 8. | Thisarticle studies the synthetic process of di - n - hexyl adipate . it discusses the kinds ofnon - acidic catalyst used in the process . it points out the characteristic and the keytechnology of the synthesis , and the application of the product in pvb resin 研究了己二酸二正己酯的合成方法,介绍了己二酸二正己酯合成中的非酸催化剂的种类,讨论了工艺特点、工艺关键以及产品与pvb树脂配套应用检验结果。 |
| 9. | In this thesis , we studied optical properties of eu3 + and mn2 + doped zns nanocrystallites . the new results are as follows : 1 . zns : mn2 + ethanol colloids were synthesized and dispersed into pvb film . the luminescence enhancement of mn2 + was observed after ultraviolet irradiation 制备出纳米zns : mn2 +乙醇溶胶和pvb薄膜样品,均观察到紫外光辐照下的荧光增强现象,增长倍数超过20倍,高于以前的报导,并发现样品在固体薄膜和溶胶中有不同的荧光增强行为。 |
| 10. | The results indicate that the sort of walling material is the most important factor in bond capacity of mortar , the mixed quantity of polymer and mortar strength follows , and there is a remarkable increase in mortar bond strength when the mixed quantity of pvb and mc is 20 % ~ 30 % and 0 . 05 % ~ 0 . 1 % respectively 结果表明:块体类别是最主要的影响因素,其次是聚合物掺量和砂浆强度;当聚乙烯醇缩丁醛和甲基纤维素的掺量分别为水泥质量的20 % ~ 30 %和0 . 05 % ~ 0 . 1 %时,可较大幅度提高砂浆的黏结强度。 |
