在此前新聞小編講述過了硬質PVC低發泡板的生産工藝流程與原理，今天，小編將從硬質PVC低發泡板生产设备講起。

PVC發泡板

硬質PVC低發泡板是一種新型的人造材料，又稱爲雪弗板，從其密度、性能、二次加工（刨、鋸、釘、膠接等）及保溫、隔音、防潮、防蟲、阻燃等性能上看，都是木材的理想替代品。

　　硬質PVC低發泡板的挤出设备包括挤出机，低發泡擠出可采用單螺杆擠出機和雙螺杆擠出機；模頭，在模頭设计时要有足够的压力以防止塑料熔体在模腔内发泡；真空冷卻定型裝置，采用較的幹式真空定型和濕式真空定型並用的方法；牽引機，具備無級變速調節；切割、收集等裝置，硬質PVC低發泡板切割和收集装置与一般普通硬質PVC制品的生産線相同主要原料。

He talkee, "My can go all light"— "Precisely. And because you have seen[Pg 179] more than I have you are less able to understand the matter than I am. You cannot see the wood for the trees. Again, you were frightened out of your life. Your scientific instincts were stampeded. You saw only a hideous malformation, a neural freak, a preposterous human machine. It was inconceivable that you should have been able to think clearly under the circumstances. Consider the matter in the sober aftermath of reason, and you must agree with me that it is really not more extraordinary that a man should function by mechanical means than that he should function at all." Even before that, on August 11th I sent a communication, by post or cable (De Tijd, No. 20353), in which the following is found:— Nor did Socrates only consider the whole conception in relation to its parts, he also grouped conceptions together according to their genera and founded logical classification. To appreciate the bearing of this idea on human interests it will be enough to study the disposition of a code. We shall147 then see how much more easy it becomes to bring individual cases under a general rule, and to retain the whole body of rules in our memory, when we can pass step by step from the most universal to the most particular categories. Now, it was by jurists versed in the Stoic philosophy that Roman law was codified, and it was by Stoicism that the traditions of Socratic philosophy were most faithfully preserved. But a chicken was no more to be had in Chattanooga than a Delmonico banquet. The table of the Major-General commanding the Army of the Cumberland might have a little more hardtack and pork on it than appeared in the tents of the privates, and be cooked a little better, but it had nothing but hardtack and pork. "There goes some men for the ferry now. Why can't we go with them?" persisted the boy. Si walked out some distance in front of them, pulling as he walked some of the tender, fragrant, spicy young leaves of the sassafras, and chewing them with gusto. Arriving at the top of a rise he selected a young shrub, pulled it up, carefully loosed its root from the mulchy soil, and cut it off with his knife. His careless deliberation calmed the overwrought nerves of the boys, and when he returned they had their canteens filled, and walked back composedly to the fires, when they suddenly remembered that they were as hungry as Si and Shorty, and fell to work cooking their suppers. "They're going to fight," Dr. Haenlingen said. "When the Confederation attacks, they're going to fight back. It's senseless: even if we won, the Confederation fleet could blockade us, prevent us getting a shipment out, bottle us up and starve us for good. But they don't need sense, they need motive, which is quite a different thing. They're going to fight—both because they need the punishment of a really good licking, and because fighting is one more way for them to deny their guilt." They reached Odiam, both feeling that the glory of those last three months had departed. The sight of Boarzell, lying black and hullish across their path, had made them realise that their happiness was but an interval, an interlude between more significant, more sinister things. Naomi had lost her peace and confidence, she seemed to avoid her husband, was tongue-tied in his presence, gave him a hurried good night from the door. Reuben was silent and meditative—when his eyes rested on Naomi they were half regretful. They were hungry ... their arms wound about each other and their faces pressed close, now cheek to cheek, now with lips fluttering together in those sweet kisses of youth which have so much of shyness in their passion. Caro trembled so that she could hardly move, and once again came the feeling that she ought to turn and run back into the house. But she was powerless in the clutch of her long-thwarted emotions. The tipsy sailor became God to her, and she followed him out on to the Moor. HoME 欧美色图2016.3.28ENTER NUMBET 0019www.timesgood.com.cn
