德州注塑加工出現黑點的原因是什麽？

发布者：德州注塑加工日期：2022-12-23

　　在當前的塑料加工行業當中，德州注塑加工是一種重要的形式，很多的設備生産、配件加工都離不開德州注塑加工，所以在這樣的情況之下，市場對于德州注塑加工的關注度也不斷增強。

　　對于德州注塑加工來說，它是確保整體設備品質的關鍵，按照正規的操作來進行加工，基本上並不會出現太多的品質問題，但是有些情況之下，也會造成一些小問題出現，比如說出現的一些黑點。

　　那麽德州注塑加工當中所出現的黑點，又都是因爲什麽原因的影響呢?

　　1、機台方面。由于加熱控制系統失控，導致料筒過熱造成分解變黑;或者由于螺杆或料筒的缺點使熔料卡入而囤積，經受長時間固定加熱造成分解，應檢查過膠頭套件是否磨損或裏面是否有金屬異物。

　　2、注塑模具方面。注塑模具排氣不順，易燒焦，或澆注系統的尺寸過小，剪切過于厲害造成焦化。

　　3、塑料件方面。産品揮發物過多，濕度過大，雜質過多，再生料過多，受汙染。

　　4、加工方面。壓力過大，速度過高，背壓過大，轉速過快都會使料溫分解。

MARY THINKING WHAT SHE WOULD LIKE FROM JAPAN. MARY THINKING WHAT SHE WOULD LIKE FROM JAPAN. "How did I hear them? Let me see. Oh, yes! from--from Harry." "No, he's Federal, Confederate or guerilla as it may suit his bloody ends." In forming an estimate of the value of his services, an apprentice sees what his hands have performed, compares it with what a skilled man will do, and estimates accordingly, assuming that his earnings are in proportion to what has been done; but this is a mistake, and a very different standard must be assumed to arrive at the true value of such unskilled labour. Flat or plane joints nearly always admit of adjustment between the fitted surfaces; that is, the material scraped or ground away in fitting can be compensated by bringing the pieces nearer together; but parallel cylindrical joints cannot even be tried together until finished, consequently, there can be nothing cut away in trying them together. Tapering, or conical joints, can of course be trial-fitted, and even parallel fits are sometimes made by trial, but it is evident that the only material that can [149] be cut away in such cases, is what makes the difference between a fit too close, and one which will answer in practice. Three youths, thrilled by the prospect of a mysterious adventure, and a war pilot, intent on a friendly service, discussed plans for protecting the Everdail Emeralds. He reflected that it is a trait of the semi-civilized and of children that they like their tales often retold. But he did not say so. He was holding that in reserve. Instead, he changed the subject, with an abrupt inquiry as to whether she meant to ride to-day. "I suppose not?" he added. "Neither of us is a-going to die till we've put down this damned rebellion, and got home and married our girls," gasped Shorty with grim effort. "You can jist telegraph that home, and to ole Abe Lincoln, and to all whom it may concern." "Can you see any path through this abatis, Sergeant?" nervously asked Harry Joslyn. Cadnan closed his eye for a second, to relax, but he found he wanted to talk. His first day in the world of the masters had been too confusing for him to order it into any sensible structure. Conversation, of whatever kind, was a release, and might provide more facts. Cadnan was hungry for facts. A machine could have done the job very easily, but machines were expensive. An Albert could be taught in a week. Chapter 3 She was silent, and the firelight playing in her soft, lively eyes gave her a kind of mystery which for the first time allowed Reuben a glimpse into the sources of her attraction. She was utterly unlike anything there was or had been in his life, the only thing he knew that did not smell of earth. The pity of it was that he loved that strong-smelling earth so much. He disdained the villeins, and he felt that the free men would disdain him. He would not associate with those now, whom, in his day of prosperity, he had sought to befriend, and whose degraded state he had wished to ameliorate; nor would he associate with those who had so lately been his compeers, lest they should seek to befriend him or ameliorate his lot. The weapons wielded by the powerful arm of the smith were not such as those, who had little interest in the detention of the monk, would care to encounter. The attacks of the castle people relaxed, the energy of the rescuers increased; the smith, with the skill of a practised workman, loosed the fastenings of the postern gate, and the band, rushing through and forcibly closing it after them, father John was again a free man. John Ball, whatever he may have felt, had too much good sense to weaken his ascendancy by making any acknowledgment. If he was the soul of the confederacy—Wat Turner, or Tyler, as we shall henceforward call him, was the body;—he might inspire the thought, but Tyler must direct the physical movement: and, therefore, it was absolutely requisite that the smith should in himself set the wholesome example of being amenable to discipline. The monk, therefore, without further comment, began to ask of their capabilities, their resources, and arrangements; and it was finally agreed upon, after much deliberation, that Tyler should command the Kentish division, and Jack Oakley, or, as he now chose to style himself, Jack Straw (probably from the then custom of bailiffs wearing straws in their hats), the bodies that were to march upon London from Essex.
