Quadrant's new TIVAR® HPV gives conveying systems a performance, cost and safety boost
7/26/2012
Quadrant launches new TIVAR® polyethylene (PE) bearing grade TIVAR HPV to support improvements to the productivity and safety of conveying systems and a reduction in maintenance.
New TIVAR HPV is an ultra high molecular weight polyethylene (UHMW-PE) developed specifically for wear components subject to challenging production environments, such as high speeds, high temperatures, high loads and aggressive cleaning agents. It is Food Contact compliant and available as semi-finished material and custom machined parts.
TIVAR HPV has an innovative, built-in dry lubricant which gives it a Limiting Pressure Velocity (LPV) value 18%* higher than competitive material, resulting in reduced pressure sensitivity for finished parts. POM-C counterplate tests by Quadrant indicate that TIVAR HPV offers the lowest coefficient of friction (COF) value on the market, with a reduction of up to 80% in comparison to other UHMW-PE materials.
As a result, components made with TIVAR HPV show improved sliding behaviour and high wear and abrasion resistance. This avoids excessive wear and deformation of parts to support the longest possible lifecycle in conveyors, and allow cost, time and safety benefits.
New TIVAR HPV is suitable for all touch points in a conveyor system where friction and wear appears, such as chain guides, sliding strips and guides, rollers, single and multiple corner wear bends, and straight guides. As a fully certified Food Contact compliant material, it enables system operators to build-up a production line in accordance with the latest Food Regulation requirements.
The superior sliding performance reduces friction of components against a mating partner. From a cost perspective, this reduces energy use as considerably less drive is required to push the system. It also better protects parts from wear, in particular expensive sliding partners such as chains and belts, leading to a reduction in the purchasing and installation of replacement parts.
Longer performance periods without maintenance improve the overall safety of the system for operators.
The sliding advantage generates smoother, quieter operation without the need for external lubricants such as oil and grease, protecting the environment and reducing noise pollution from the equipment.

The Federal's pistol slid into its holster and his sabre flashed out. He threw its curved point up in a splendid salute. Ferry saluted with his straight blade. Then both swords rang back into their scabbards, and Jewett whirled away toward his column. For a moment we lingered, then faced to the left, trotted, galloped. Over the fence and into the road went he--went I. Down it, as we crossed, the blue column was just moving again. Then the woods on the south swallowed us up. "All right, sir." that before. Meanwhile the parallelism between Thought and Extension was not exhausted by the identification just analysed. Extension was not only a series of movements; it still remained an expression for co-existence and adjacency.412 Spinoza, therefore, felt himself obliged to supply Thought with a correspondingly continuous quality. It is here that his chief originality lies, here that he has been most closely followed by the philosophy of our own time. Mind, he declares, is an attribute everywhere accompanying matter, co-extensive and co-infinite with space. Our own animation is the sum or the resultant of an animation clinging to every particle that enters into the composition of our bodies. When our thoughts are affected by an external impulse, to suppose that this impulse proceeds from anything material is a delusion; it is produced by the mind belonging to the body which acts on our body; although in what sense this process is to be understood remains a mystery. Spinoza has clearly explained the doctrine of animal automatism, and shown it to be perfectly conceivable;569 but he has entirely omitted to explain how the parallel influence of one thought (or feeling) on another is to be understood; for although this too is spoken of as a causal relation, it seems to be quite different from the logical concatenation described as the infinite intellect of God; and to suppose that idea follows from idea like movement from movement would amount to a complete materialisation of mind; while our philosopher would certainly have repudiated Mr. Shadworth Hodgson’s theory, that states of consciousness are only connected through their extended substratum, as the segments of a mosaic picture are held together by the underlying surface of masonry. Nor can we admit that Spinoza entertained the theory, now so popular, according to which extension and consciousness are merely different aspects of a single reality. For this would imply that the substance which they manifest had an existence of its own apart from its attributes; whereas Spinoza makes it consist of the attributes, that is to say, identifies it with their totality. We are forced, then, to conclude that the proposition declaring thought and extension to be the same thing570 has no413 other meaning than that they are connected by the double analogy which we have endeavoured to explain. “Oh, he’s welcome to it,” Sandy cried. “I’ve turned over a new leaf!” “But—are they?” He pulled a wire out a trifle from the sheath. The sergeant spent more time upon the oaths with which he embellished the counter-question as to how he should know anything about it, than would have been consumed in a civil explanation. "Doctor, he can't die. He mustn't die," said Shorty in agony. "The regiment can't spare him. He's the best soldier in it, and he's my pardner." AND ENTERS UPON HIS PARENTAL RELATIONS TO LITTLE PETE SKIDMORE. "Holy smoke, look there," gasped Monty Scruggs, as a company of rebel cavalry came tearing over the hill in front, to the assistance of their comrades. "That's about it," answered Shorty disdainfully. "That's the way with all cavalry, dad-burn 'em. They're like a passel o' fice pups. They're all yelp and bark, and howl and showin' o' teeth. They're jest goin' to tear you to pieces. But when you pick up a stone or a club, or git ready to give 'em a good kick they're gone, the devil knows where. They're only an aggravation. You never kin do nothin' with 'em, and they kin do nothin' with you. I never kin understand why God Almighty wasted his time in makin' cavalry of any kind, Yank or rebel. All our own cavalry's good for is to steal whisky and chickens from honest soldiers of the infantry. The infantry's the only thing. It's like the big dog that comes up without any special remarks, and sets his teeth in the other dog. The thing only ends when one dog or the other is badly whipped and somethin's bin accomplished." "Mmm." Reuben started out of the half-waking state into which he had fallen. It was late in the afternoon, the sunlight had gone, and a wintry twilight crept up the wall. Maude the dairy-woman was looking in at the door. It was about a month subsequent to this, that one morning, as Turner was making the anvil ring with the ponderous strokes of his hammer, two retainers from the castle entered the shed, and delivered an order from De Boteler for his immediate attendance. Wat laid the hammer on the anvil, and, passing the back of his right hand across his forehead, to clear away the large drops that stood there, looked with a kind of smile at the men as he said, HoME泷泽萝拉四部和集下载
