鍍鋅卷板的強度和抗拉性能提高的原因是什麽?

来源：宝钢彩塗卷 | 發布日期：2023-11-01

鍍鋅卷板在各種領域得到廣泛應用的關鍵在于其優良的綜合性能。它以熱軋鋼帶或冷軋鋼帶爲基板，經過連續熱浸鍍鋅工藝處理後得到的一種具有高耐腐蝕性、高強度、優良的抗拉性能、良好的維護性能、易于加工和安裝、以及環保性能的重要材料。這些特性使得鍍鋅卷板成爲一種廣泛應用于各種領域的重要材料，並在各種環境下表現出良好的耐用性和穩定性。

除了耐腐蝕性強這個優點外，鍍鋅卷板還具有高強度和抗拉性能等優點。那麽，鍍鋅卷板的強度和抗拉性能提高的原因是什麽呢？

1. 镀锌处理：镀锌卷板经过镀锌工艺处理后，其表面覆盖一层锌层。这层锌层能够提高材料的硬度，进而增强其强度和抗拉性能。

2. 热浸镀锌：与电镀锌相比，热浸镀锌具有更厚的锌层和更高的附着力。热浸镀锌过程中，钢板的表面温度达到一定值后，锌液能够渗透到钢板的表面，形成一层致密的金属结构，从而显著提高钢板的抗压强度和抗拉强度。

3. 材质选择：镀锌卷板的材质也是影响其强度和抗拉性能的因素之一。目前市面上的镀锌板主要分为普通碳钢和低合金高强度钢两种。低合金高强度钢的抗拉强度和抗压强度明显高于普通碳钢，其耐蚀性能也更好，因此其抗压强度也相对较高。

總的來說，鍍鋅卷板的強度和抗拉性能提高主要得益于鍍鋅工藝處理、熱浸鍍鋅以及材質的選擇等因素。這些特性使得鍍鋅卷板在各種應用中能夠承受高壓和高負荷的工作環境，例如建築、汽車制造和機械制造等。

To regain the highroad we had turned into a northerly fork, and were in as lovely a spot as we had seen all day. Before us and close on our right were the dense woods of magnolia, water-oak, tupelo and a hundred other affluent things that towered and spread or clambered and hung. On the left lay the old field, tawny with bending sedge and teeming with the yellow rays of the sun's last hour. This field we overlooked through a fence-row of persimmon and wild plum. Among these bushes, half fallen into a rain-gully, a catalpa, of belated bloom, was loaded with blossoms and bees, and I was directing Camille's glance to it when the shots came. Another outcry or two followed, and then a weird silence. At the tavern, where we went to smarten up and to eat, we chanced upon Gregory. He was very shy of Ferry, because Ferry was a captain, but told me the latest news from the Wall place, where he had spent the previous evening. Harry and the surgeon were gone to camp, the Harpers were well, Charlotte was--better, after a bad turn of several days. We felt in duty bound to stay within hail of the telegraph office until it should close for the night; and when the operator was detained in it much beyond the usual time, Ferry, as we hovered near, said at length, "Well, I'm sorry for you, Dick; 'tis now too late for you to go yonder--this evening." "Surely, a curious coincidence!" Lawrence cried. Balmayne hastened to the door. He might want some ready lie; on the other hand, his diplomacy might be needed. But he set his teeth a trifle closer as he saw Dr. Bruce standing there. "I have been called," he said. "I'm so sorry for the poor child," she said. Considering material progress as consisting primarily in the demonstration of scientific truths, and secondly, in their application to useful purposes, we can see the position of the engineer as an agent in this great work of reconstruction now going on around us. The position is a proud one, but not to be attained except at the expense of great effort, and a denial of everything that may interfere with the acquirement of knowledge during apprenticeship and the study which must follow. Near Louvain the train had to stop for another two hours, before it was allowed to enter the station, which was quite close by. I thanked my stars that at last I got rid of my companion, who travelled on to Brussels, whereas I got out at Louvain. It was too late to be allowed to walk in the streets,199 but the commander gave me an escort of two soldiers, who were to take me to the mission house of the Fathers of the Sacred Heart. 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. Seems a little early to commence entertaining, doesn't it? A friend I'm educated! My diploma is in the bottom bureau drawer with my The Gila River cutting straight across the southern portion of Arizona, from the Alkali flats on the east to the Colorado at Yuma on the west, flowed then its whole course through desolation. Sometimes cottonwoods and sycamore trees rose in the bottom, and there was a patch of green around some irrigated land. But, for the most part, the basin was a waste of glittering sand and white dust, and beyond, the low hills, bare of every plant save a few stunted wild flowers, cacti and sage, greasewood and mesquite, rolled for miles and miles of barrenness. The chicken hawk and crow sailed through the fiercely blue sky, the air waved and quivered with incredible heat. At night malaria rose from the ground, the coyote barked and whined at the light of the brilliant stars, and the polecat prowled deliberately. "And do you care for him, too?" he asked, looking her straight in the eyes. It was a very calm question, put—he realized it with exasperation—as a father might have put it. "Hello, boys," said a weak voice, which was unmistakably Alf Russell's. The sleeping room for the Small Ones was, by comparison with the great Commons Room only the masters inhabited, a tiny place. It had only the smallest of windows, so placed as to allow daylight without any sight of the outside; the windows were plastic-sheeted slits high up on the metal walls, no more. The room was, at best, dim, during the day, but that hardly mattered: during the day the room was empty. Only at night, when the soft artificial lights went on, shedding the glow from their wall-shielded tubes, was the room fit for normal vision. There were no decorations, of course, and no chairs: the Alberts had no use for chairs, and decorations were a refinement no master had yet bothered to think of. The Alberts were hardly taught to appreciate such things in any case: that was not what they had come to learn: it was not useful. TO: Williston Reed But Realf of Grandturzel shook his head. His humiliation was more than he could bear. Without another look at Pete or Tilly, or at Reuben holding the raw chop to his eye, he turned and walked out of the room with bent head and dragging footsteps. He knew that Alice wanted him, and he knew that he wanted Alice. He did not know why he wanted Alice any more than he knew why Alice wanted him. "Wot is she?—a liddle stick of a creature. And I like big women." "I thought you might—perhaps you might help us ..." On her right hand rode her husband, clad in a tunic of fine cloth, in colour resembling the habit of his lady, and mounted on a dark, fiery charger, which with difficulty he could rein in to the slow pace of the palfrey. On the left of the lady Isabella was her brother, young Robert de Vere, and though but a boy, one might have read much in the lines of that countenance, of his future destiny. His smooth, dimpled chin, was small and round, and his mouth possessed that habitual smile, that softly beaming expression, which won for him in after years the regard of the superficial Richard; while there shone a fire in the full dark eyes, which betokened the ambitious spirit that was to animate the future lord of Dublin, and sovereign of Ireland.
