4.总功率：1.5KW 加热功率：1000W

5.縮放測量範圍：室溫～900℃

6.升温速率：5℃/min±0.3℃和 3℃/min±0.2℃可设定

7.儀器采用單片計算機、多點式程序升溫

8.儀器配有面版式打印機，可及時打印測試結果

9.裝夾具：不鏽鋼材料；抗腐蝕

10.儀器熱源采用熱板式

11.設備外形尺寸：長×寬×高（0.45×0.35×0.78）m

12.设备重量：50 Kg

試樣制作：

1. 岩棉、矿渣棉取密度为150kg/m3的试样；玻璃棉取密度为64kg/m3的试样。

2. 岩棉、矿渣棉和玻璃棉制品取实际密度的试样。

3. 岩棉壳、矿渣棉壳和玻璃棉管壳可取和管壳相同密度的板做试样

4. 有贴面的制品，应除去贴面材料。

5. 试样装入直径49±1mm的试验筒内，厚度50mm～80mm的圆柱体。

絕熱用岩棉熱荷重計算公式

d = （A-B）/A *100%

d——试样厚度的收缩率 A——在室温加热荷重时的试样厚度，单位mm

B—— 温度t 时的试样厚度，单位mm

注：由試樣厚度收縮率與溫度關系的計算，以內插法求出試樣厚度收縮率爲10%的爐內溫度，取兩次測量的算術平均值，精確到10℃，作爲試樣的熱荷重收縮溫度。

設計標准：

GB/T11835-2007 绝热用岩棉、矿渣棉及其制品

適用標准：

ISO1716-2002 建筑产品对火焰试验的反应燃烧热的测定

THE GOD OF THE KITCHEN. THE GOD OF THE KITCHEN. It's like farming. You can have extensive farming and intensive I can read your secretary's letter now: And at this day the high road passes Secundra Bagh in ruins, and on the ground where Nana Sahib's soldiers fell, huge flowers are strewn of "flame of the forest" fading into hues of blood. The stranger had a pleasant, round face, with eyes that twinkled in spite of the creases around them that showed worry. No wonder he was worried, Sandy thought: having deserted the craft they had foiled in its attempt to get the gems, the man had returned from some short foray to discover his craft replaced by another. “All right, buddy,” admonished Jeff. “Stick to your job. Sandy or Dick will read the dots and dashes—if he’s using Morse code——” In Europe, Pitt was still bent on those attacks on the coast of France which long experience had shown were of little use as means of successful war, but highly objectionable, as fraught with excessive inhumanity to the innocent people of the seaboard. This, his second expedition, was aimed at St. Malo. A fleet of eighteen ships of the line, thirteen frigates, with sloops, fire-ships, and bomb-ketches, was put under the command of Lord Howe; but as Sir Edward Hawke, his senior, struck his flag, and refused to serve as second, Lord Anson, to get rid of the difficulty, put himself nominally at the head of the squadron. The command of the troops was given to the Duke of Marlborough, a brave man, but destitute of the genius of his father, and Lord George Sackville and Lord Granby were under him. There were fourteen thousand troops of the line and six thousand marines. With these went a number of aristocratic volunteers, amongst them Lord Downe, Sir John Armitage, and Sir John Lowther, the possessor of fourteen thousand pounds a-year. On the 5th of June, 1758, the transports anchored in Cancale Bay, and next day the troops were landed and led against St. Malo. This town, built on one of a cluster of granite rocks which rise out of the sea on that iron-bound coast, they found too strongly fortified to storm, but they burnt a hundred and thirty privateers and a great quantity of small craft in the harbour, and then returned to their ships. They then sailed for Le Havre, but were prevented by the wind from doing the same damage, and so continued their voyage to Granville and Cherbourg, whence they were driven by storm; and thereupon coasting a considerable way farther, but to no purpose, the fleet returned to Portsmouth, the main result being a heavy expense. Fox and the Opposition in the Commons called it breaking windows with guineas; and the old king, who had expressed his dislike of this sort of warfare, said we should brag of having burnt the French ships, and the French of having driven us away. When the boys were properly washed and combed, Mrs. Klegg, her kind, motherly face beaming with consciousness of good and acceptable service, would enter with a large tray, laden with fragrant coffee, delicious cream, golden butter, her own peerless bread and bits of daintily-broiled chicken. "Open it and read it, Maria," said Si, to whom reading of letters meant labor, and he was yet too weak for work. "Come, now, be reasonable," pleaded Bob. "Why can't you and I go along together and run the thing? We'll pull together all right. You know I've been a Sergeant for a long time, and know all about the handling of men." "No, no; give him a show for his life," answered Shorty, laying his hand on Pete's gun. "That old-time religion." HoME 销售台湾食品是否要换中文标签ENTER NUMBET 0019cdwj888.com.cn
