橫絲岩棉板與豎絲岩棉板的區別？

作者：潘先生閱讀量：发布日期： 2022/9/23 10:00:27

信息摘要：

岩棉作爲新型的保溫防火材料，近幾年應用十分廣泛。主要原材料是優質的玄武岩、白雲石，用1450℃以上高溫將其溶化，然後采用先進的四軸離心機高速離心成纖維，同時噴入一定量的粘結劑、防塵油、憎水劑後經集棉機收集、通過擺錘法工藝，加上三維法鋪棉後進行固化、切割，形成不同規格和用途的岩棉産品。

岩棉保溫板廠家根據産品生産時用的方法不同把岩棉板分爲了橫絲和豎絲岩棉板兩種，說到底纖維的物理分布是這兩種材料的根本的區別。先從大的方面來說說看兩者間的區別，橫絲與豎絲岩棉的主要不同在于生産工藝的不同。

橫絲的防火岩棉板是使用了沈降法生産工藝生産而成的一種岩棉保溫板制品。沈降法加工出來的岩棉纖維爲平面分布的，均勻性差表現在了密度和粘結劑上，使板材的抗壓強度及層間結合強度受到了一定的影響。

豎絲防火岩棉板則是根據擺錘法或三維法岩棉生産工藝生産而成的岩棉制品。用擺錘法加工出來的豎絲防火岩棉板的抗壓強度和層間結合強度得到了很大的提高。整體比橫絲防火岩棉板性能強了很多。

岩棉保溫板廠家生産的橫絲和豎絲岩棉制品的性能主要表現在抗拉及抗壓強度，導熱系數等等方面。豎絲岩棉板要比橫絲岩棉板的抗拉強度高出1-2倍，兩者的抗壓強度相近，但豎絲岩棉板的導熱系數略低于橫絲防火岩棉板。此外豎絲防火岩棉板克服了橫絲防火岩棉板抗拉強度較低的缺點，可以在很大程度上滿足外牆保溫系統的使用需求。

A CHRISTENING IN JAPAN. A CHRISTENING IN JAPAN. His face suddenly cleared, and all trace of the canine resemblance vanished as if by magic. He got up and took two or three jerk-like strides up and down the room. "Must keep going—when I feel like this—either food or violent stimulus—otherwise the confounded thing runs down—and there you are." "As you see, this is from the solicitor who employs you," he said. "If I like to change my mind, and ask you to go you are to obey. I ask you to go. Say nothing of this, and I will see you are suitably rewarded in the morning." "All the women and children had been taken to a convent, where they were kept imprisoned for four days, without hearing of the fate of their beloved ones. They themselves expected to be shot in their turn. Round about them the burning of the town went on. “We mustn’t waste any more time,” cried Larry, eagerly. “There are twenty-nine more chunks in the seaplane. Let’s fly there, Jeff, and get it.” 238 The mesquites were very near. She bent down over the horse's neck and spoke to him. His stride lengthened out yet more. She drew the little revolver, and cocked it, still bending low. If they were to fire at her, the white gown would make a good mark; but she would show as little of it as might be, and she would not waste time answering shots, if it could be helped. As far as his voice could reach, the rough soldiers, officers and men, stopped to listen to him—listened to him with emotions far too deep for the cheers that usually fly to the lips of soldiers at anything that stirs them. The higher officers quit talking of the plans of the morrow; the minor ones stopped, pen in hand, over their reports and requisitions; the busy Surgeons stayed their keen knives; the fussy Orderly-Sergeants quit bothering about rations and details; the men paused, looked up from their cards and cooking until the hymn was sung through. He began taking it off when he heard someone beside them say: "What dost thou here, John Kirkby, and why these screams?" HoME 一级毛片免费完整视频aENTER NUMBET 003www.qayd.com.cn
