石膏線條幹燥與除濕機有什麽關(guān)聯(lián)？

返回列表 來源：普瑞泰除濕發(fā)布日期： 2019.05.20

石膏線條作為裝飾工藝品，是裝修場合常見的裝修元素。生產(chǎn)石膏線條過程中最重要的是除去石膏中的水分，今天普瑞泰小編探討一下石膏線條幹燥與除濕有什麽關(guān)聯(lián)？

石膏線條是用水與石膏粉進行攪拌混合後進行塑形，再進行脫模幹燥。幹燥過程是生產(chǎn)石膏線條非常重要的環(huán)節(jié)，如果幹燥不當，會導(dǎo)致石膏線條發(fā)斑、黴變、變色，嚴重影響石膏產(chǎn)品的品質(zhì)，引發(fā)後續(xù)的重新制作而提高成本，因此防潮幹燥對石膏線條的生產(chǎn)非常重要。

以前石膏線條使用傳統(tǒng)的自然晾幹法，在夏季露天的曝曬下，過高的溫度極可能會使石膏開裂，冬季溫度低幹燥時間也會隨之增加，幹燥時間過長也會導(dǎo)致石膏發(fā)黴。後來人們開始嘗試人工加熱幹燥，但由于人工加熱幹燥的溫度控制不穩(wěn)定，還是會出現(xiàn)高溫導(dǎo)致石膏變色開裂的問題。

隨著科技的發(fā)展，經(jīng)過多年實踐經(jīng)驗，石膏線的幹燥過程中眾多石膏線生產(chǎn)企業(yè)開始選用轉(zhuǎn)輪除濕機來進行幹燥。石膏線條在幹燥過程中會有大量的水分被蒸發(fā)出去，彌漫在幹燥房，以往大多會使用排風(fēng)扇進行除濕，除濕的同時也會將幹燥房間的熱量排出，導(dǎo)致會增加了幹燥成本。而除濕機除去水分的同時也能保證溫度、熱量的穩(wěn)定，不會增加多余的成本。

"You are a one," she declared. Then she looked at Mr. Flack, who sat unmoved. "Why don't you laugh. It would do you good. You take everything so serious." "Gamages," interrupted the Clockwork man, "wait—I seem to understand—it comes back to me—universal providers—cash account—nine and ninepence—nine and nine[Pg 97]pence—nine and ninepence—I beg your pardon." "It's about those letters I found in your possession," Prout said, "the letters to you from your brother. I know they are from your brother, because I have seen him, and also his handwriting. You need not be afraid of him, because he is far beyond being injured by any one in the world." "I require that everywhere a strict investigation shall take place into the conduct of the soldiers with regard to the life and property of the civilian population. But what afforded the most valuable education in this sense was their system of free government, involving, as it did, the supremacy of an impersonal law, the subdivision of public authority among a number of magistrates, and the assignment to each of certain carefully defined functions which he was forbidden to exceed; together with the living interest felt by each citizen in the welfare of the whole state, and that conception of it as a whole composed of various parts, which is impossible where all the public powers are collected in a single hand. Returning to Epicurus, we have next to consider how he obtained the various motions required to bring his atoms into those infinite combinations of which our world is only the most recent. The conception of matter naturally endowed with capacities for moving in all directions indifferently was unknown to ancient physics, as was also that of mutual attraction and85 repulsion. Democritus supposed that the atoms all gravitated downward through infinite space, but with different velocities, so that the lighter were perpetually overtaken and driven upwards by the heavier, the result of these collisions and pressures being a vortex whence the world as we see it has proceeded.163 While the atomism of Democritus was, as a theory of matter, the greatest contribution ever made to physical science by pure speculation, as a theory of motion it was open to at least three insuperable objections. Passing over the difficulty of a perpetual movement through space in one direction only, there remained the self-contradictory assumption that an infinite number of atoms all moving together in that one direction could find any unoccupied space to fall into.164 Secondly, astronomical discoveries, establishing as they did the sphericity of the earth, had for ever disproved the crude theory that unsupported bodies fall downward in parallel straight lines. Even granting that the astronomers, in the absence of complete empirical verification, could not prove their whole contention, they could at any rate prove enough of it to destroy the notion of parallel descent; for the varying elevation of the pole-star demonstrated the curvature of the earth’s surface so far as it was accessible to observation, thus showing that, within the limits of experience, gravitation acted along convergent lines. Finally, Aristotle had pointed out that the observed differences in the velocity of falling bodies were due to the atmospheric resistance, and that, consequently, they would all move at the same rate in such an absolute vacuum as atomism assumed.165 Of these objections Epicurus ignored the first two, except, apparently, to the extent of refusing to believe in the antipodes. The third he acknowledged, and set himself to evade it by a hypothesis striking at the root of all scientific86 reasoning. The atoms, he tells us, suffer a slight deflection from the line of perpendicular descent, sufficient to bring them into collision with one another; and from this collision proceeds the variety of movement necessary to throw them into all sorts of accidental combinations. Our own free will, says Lucretius, furnishes an example of such a deflection whenever we swerve aside from the direction in which an original impulse is carrying us.166 That the irregularity thus introduced into Nature interfered with the law of universal causation was an additional recommendation of it in the eyes of Epicurus, who, as we have already mentioned, hated the physical necessity of the philosophers even more than he hated the watchful interfering providence of the theologians. But, apparently, neither he nor his disciples saw that in discarding the invariable sequence of phenomena, they annulled, to the same extent, the possibility of human foresight and adaptation of means to ends. There was no reason why the deflection, having once occurred, should not be repeated infinitely often, each time producing effects of incalculable extent. And a further inconsequence of the system is that it afterwards accounts for human choice by a mechanism which has nothing to do with free-will.167 [54] "You'll cut that meat straight across, and give me my right share o' lean, you puddin'-headed, sandhill crane," shouted Harry. An angry mix-up, school boy rules, followed, to the great detriment of the rations. Si and Shorty rushed up, separated the combatants, and administered shakes, cuffs, and sharp reprimands.
