GB 18173.1-2006防水材料粘接剥离强度试验

日前，三思泰捷为广西某节能产品检测公司提供了多台用于防水卷材、石膏板等建筑材料的拉力试验机。高分子防水材料，在建筑领域有广泛应用。按国标GB 18173.1-2006要求，高分子防水材料片材粘接剥离强度试验需要使用拉力试验机，三思泰捷相关设备如图。

要求試驗溫度23度左右，相對濕度45%~65%

制样要求：纵向裁取200mm*150mm试片4块，将与片材配套的膠粘劑涂在试片上，然后将两片片材对正粘贴，停放168h后裁取10个200mm*25mm的试样，取出5个试样在水中放置168h，取出后再标准试验条件下停放4h备用。

試驗程序：將試樣分別夾在拉力試驗機上，夾持部位不能滑移，試驗機以100mm/min速度勻速拉伸剝離，試樣剝離長度至少需125mm，剝離力以拉伸過程中（不包括最初的25mm）的平均力值來表示。

試驗項目：拉伸、壓縮、彎曲、180度剝離

送檢單位：廣西某綠色節能産品檢測公司

"And sure," she said, "and I hope that wretched old Feejee won't be in Japan at all, at all, and the horrid haythens won't roast him." THIRD-CLASS PASSENGERS. THIRD-CLASS PASSENGERS. I was about to put a false meaning even on that, when she added "We don't need the ford this time of year; let us ride back as if we gave up the trip--for there may be a vidette looking at us now in the edge of those bushes--and as soon as we get where we can't be seen let us take a circuit. We can cross the creek somewhere above and strike the Wiggins road up in the woods. You can find your way by the blessed stars, can't you--being the angel you are?" "Good-night, gentlemen," said the doctor at last. As he passed into the darkness Quinn bent a mock frown upon his young superior. It would require a mathematical diagram to describe the incident with absolute accuracy. The Curate, of course, had heard nothing about the Clockwork man's other performances; he had scarcely heeded the hints thrown out about the possibility of movement in other dimensions. It seemed to him, in the uncertain light of their surroundings, that the Clockwork man's right arm gradually disappeared into space. There was no arm there at all. Afterwards, he remembered a brief moment when the arm had begun to grow vague and transparent; it was moving very rapidly, in some direction, neither up nor down, nor this way or that, but along some shadowy plane. Then it went into nothing, evaporated from view. And just as suddenly, it swung back into the plane of the curate's vision, and the hand at the end of it grasped a silk hat. Good fitting is often not so much a question of skill as of the standard which a workman has fixed in his mind, and to which all that he does will more or less conform. If this standard is one of exactness and precision, all that is performed, whether it be filing, turning, planing, or drawing, will come to this standard. This faculty of mind can be defined no further than to say that it is an aversion to whatever is imperfect, and a love for what [171] is exact and precise. There is no faculty which has so much to do with success in mechanical pursuits, nor is there any trait more susceptible of cultivation. Methodical exactness, reasoning, and persistence are the powers which lead to proficiency in engineering pursuits. I was the only civilian in that road, and the soldiers, with much curiosity, stared at me. Whenever I noticed an officer, I gave an elaborate military salute, and with such an air that the officers, although hesitating at first, did not fail to return the salute. The reformed system of education was to be not only moral and religious but also severely scientific. The place given to mathematics as the foundation of a right intellectual training is most remarkable, and shows how truly Plato apprehended the conditions under which knowledge is acquired and enlarged. Here, as in other respects, he is, more even than Aristotle, the precursor of Auguste Comte. He arranges the mathematical sciences, so far as they then existed, in their logical order; and his remarks on the most general ideas suggested by astronomy read like a divination of rational mechanics. That a recommendation of such studies should be put into the mouth of Socrates is a striking incongruity. The older Plato grew the farther he seems to have advanced from the humanist to the naturalistic point of view; and, had he been willing to confess it, Hippias and Prodicus were the teachers with whom he finally found himself most in sympathy. We are told that when his end began to approach, the dying philosopher was pressed to choose a successor in the headship of the School. The manner in which he did this is289 characteristic of his singular gentleness and unwillingness to give offence. It was understood that the choice must lie between his two most distinguished pupils, Theophrastus of Lesbos, and Eudêmus of Rhodes. Aristotle asked for specimens of the wine grown in those islands. He first essayed the Rhodian vintage, and praised it highly, but remarked after tasting the other, ‘The Lesbian is sweeter,’ thus revealing his preference for Theophrastus, who accordingly reigned over the Lyceum in his stead.179 Abibulla saw them off with great deference and a contrite air, and watched their retreat; then, as[Pg 260] I was about to send him to despatch the message, he was indignant. The police! What could they do to a sahib like me? It was all very well to frighten poor folks—it was a sin to waste money in asking for a reply which I should never be called upon to show—and so he went on, till I made up my mind to think no more of the matter. And whenever I met the chief at the bazaar or by the Jellum, he only asked after my health and my amusements. Felipa shook her head at Ellton. "Don't get yourself excited about it, Jack dear," she soothed, and Ellton also tried to quiet him. The last straw was laid on when an Indian policeman arrested a young buck for some small offence. The buck tried to run away, and would not halt when he was told to. The chief of police fired and killed a squaw by mistake; and though he was properly sorry for it, and expressed his regret, the relatives and friends of the deceased squaw caught him a few days later, and cutting off his head, kicked it round, as they had seen the White-eye soldier do with his rubber foot-ball. Then they, aroused and afraid too of punishment, fled from the reservation and began to kill. "Yes," he assured her unmoved, "you are. At least you are going to do that, or go to jail." The poor man looked as miserable as if put in a strait-jacket, but tried to literally obey instructions. "Probably it was Corpril Elliott's good management," suggested Gid Mackall, whose hero-worship of Shorty grew apace. "I tell you there aint a trick o' soldierin' that he aint up to." Then suddenly she was silent—and Reuben kissed her. "You finish your tea," he said to George, "and bring some more, Maudie, for these gentlemen," nodding kindly to the two young men, who stared at him as if they thought he had taken leave of his senses.
