搪玻璃設備—搪玻璃反應釜的用途及使用条件

搪瓷設備是一种具有耐腐蚀玻璃衬里的钢制化工容器，其钢制罐体确保了承压能力，罐内涂搪的玻璃衬里又使其具有可靠的耐腐蚀性能。这种耐压与耐腐蚀性结合于一体的独特性能，极大地扩展了设备的适用范围，使其应用于化工、石油化工、农药、医药、冶金、食品等各个工业部门。在众多的化学反应条件下，搪玻璃設備不但能够替代价格昂贵的不锈钢制容器，而且广泛地应于那些不能使用不锈钢制容器的腐蚀条件中。搪瓷层能耐大多数无机酸、有机酸、有机溶剂等介质，尤其在盐酸、硝酸、王水等介质中具有优良的耐腐蚀性能。但不能在下列条件下使用：
(1)任何濃度及任何溫度的HF都不能耐腐蝕；
(2)磷酸：濃度30%以上、溫度大于180℃時腐蝕強烈；
(3)鹽酸：濃度10--20%,溫度大于150℃時，腐蝕強烈；
(4)硫酸：濃度10--30%,溫度大于200℃時不能耐腐蝕；
(5)堿液：PH大于或等于12、溫度大于100℃時，不能耐腐蝕。
搪玻璃設備之耐腐蚀性基于在玻璃衬里与介质接触后，形成一层硅氧保护膜，此膜阻止了介质对罐体的腐蚀。当搪玻璃层接触强碱液时，其表面不能形成硅氧保护膜，致使碱液不断向玻璃层深部侵蚀，而强碱浓度越高、温度越高其被侵蚀的程度越大。沸腾状态的强碱溶液具有最大的侵蚀能力。
在實際情況中，由于生産並非使用一種反應介質，多種酸在一起時由于“混酸效應”多數情況下會降低離子活度，減輕腐蝕程度。建議用戶在腐蝕程度不確定的情況下亦應與生産廠家聯系。在搪玻璃適用範圍中，有一個很重要的問題，這就是設備對溫度的適用性。顯而易見，鋼與玻璃層的熱膨脹系數不同，當設備溫度急劇變化時，所産生過大的應力會導致爆瓷而損壞設備。爲避免這種損壞我們在介質適用範圍內還應注意設備的溫差，即冷沖擊110℃，熱沖擊120℃，所以在設備加熱或冷卻過程中應緩慢進行。

He turned slowly, as though considering whether to return and explain matters to the curate. "I must have frightened him," he whispered, almost audibly, "but I only wanted[Pg 104] to show him, and the parrot cage happened to be handy." She was alone now; she could give vent to her passionate anger. She smashed her fan across her knee, she tore her long gloves into fragments. Dimly, in a mirror opposite, she saw her white ghastly face, and the stain of blood where she had caught her lips between her teeth. Machine-drawing may in some respects be said to bear the same relation to mechanics that writing does to literature; persons may copy manuscript, or write from dictation, of what they do not understand; or a mechanical draughtsman may make drawings of a machine he does not understand; but neither such writing or drawing can have any value beyond that of ordinary labour. It is both necessary and expected that a draughtsman shall understand all the various processes of machine construction, and be familiar with the best examples that are furnished by modern practice. In a café, lower down, near the canal I saw a number of German soldiers, and was successful in having a chat with the inn-keeper, at the farthest corner of the bar. I asked him, of course, what they meant by burning the village, and he told me that the Germans had made a number of unsuccessful attacks on Fort Pontisse, until at last they reduced it to silence. They were now so near that they could open the final assault. They were afraid, however, of some ambush, or underground mine, and the Friday before they had collected the population, whom they forced to march in front of them. When they had got quite near they dared not enter it yet, and drove the priest and twelve of the principal villagers before them. That is how Pontisse was conquered. I understood and respected the restraint of the Belgian primate, who went on then: Xenophon has recorded another dialogue in which a young man named Euthydêmus, who was also in training for a statesman, and who, as he supposed, had learned a great deal more out of books than Socrates could teach him, is brought to see how little he knows about ethical science. He is asked, Can a man be a good citizen without being just? No, he cannot.—Can Euthydêmus tell what acts are just? Yes, certainly, and also what are unjust.—Under which head does he put such actions as lying, deceiving, harming, enslaving?—Under the head of injustice.—But suppose a hostile people are treated in the various manners specified, is that unjust?—No, but it was understood that only one’s friends were meant.—Well, if a general encourages his own army by false statements, or a father deceives his child into taking medicine, or your friend seems likely to commit suicide, and you purloin a deadly weapon from him, is that unjust?—No, we must add ‘for the purpose of harming’ to our definition. Socrates, however, does not stop here, but goes on cross-examining until the unhappy student is reduced to a state of hopeless bewilderment and shame. He is then brought to perceive the necessity of self-knowledge, which is explained to mean knowledge of one’s own powers. As a further exercise Euthydêmus is put through his facings on the subject of good and evil. Health, wealth, strength, wisdom and beauty are mentioned as unquestionable goods. Socrates shows, in the style long afterwards imitated by Juvenal, that141 they are only means towards an end, and may be productive of harm no less than good.—Happiness at any rate is an unquestionable good.—Yes, unless we make it consist of questionable goods like those just enumerated.91 was still at college, and if I would accept some advice, he would [Pg 25] A few minutes before seven they all came back into the sitting room. The men wore black coats, by way of compromise, and Mrs. Kirby and the children were in white. "Give me the keys—all the keys." Mar had left London on the 2nd of August to raise the Highlands. In order to blind the agents of Government he ordered a royal levée on the 1st, and on the following night got on board a collier bound for Newcastle, attended by Major-General Hamilton and Colonel Hay. From Newcastle they got to the coast of Fife in another vessel. On the 6th of September he raised the standard of the Chevalier at Kirkmichael, a village of Braemar. He was then attended by only sixty men, and the Highland chiefs, extremely alive to omens, were startled by the gilt ball falling from the summit of the pole as it was planted in the ground. The standard was consecrated by prayers, and he was in a few days joined by about five hundred of his own vassals. The gentlemen who came on horseback, only about twenty at first, soon became several hundreds, and were named the Royal Squadron. The white cockade was assumed as the badge of the insurgent army, and clan after clan came in; first the Mackintoshes, five hundred in number, who seized on Inverness. James was proclaimed by Panmure at Brechin, by the Earl[29] Marshal at Aberdeen, by Lord Huntly at Gordon, and by Graham, the brother of Claverhouse, at Dundee. Colonel Hay, brother of the Earl of Kinnaird, seized Perth, and in a very short time the country north of the Tay was in the hands of the insurgents. "Yes, sir," answered Shorty. "I'm afraid we can't," Rogier put in, almost apologetically. "Hallo—confederates! you have forgotten one thing, which, after all, may do us more good than all the conditions put together. What think ye of burning all the deeds and court-rolls of manors we can lay our hands on? The knaves will find it no easy matter to prove their title to the land, or to the rent or to the bondman either." HoME 私爱格免费一级视频ENTER NUMBET 002zj1023.cn
