四氟拉西环在多个领域发挥重要作用，包括化工、化肥、烧碱生产、石油加工以及电力和制药行业。这种材料因其卓越的耐腐蚀性能而受到青睐。以下是四氟拉西环的一些规格参数，详细信息如下：
名称 | 规格（d×h×δ mm） | 比表面积（α m2/m3） | 空隙率（ε m3/m3） | 堆积个数（η n/m3） | 干填料因子（α/ε³ m-1）
-----|-------------------|---------------------|------------------|--------------------|----------------
四氟拉西环 | 15×15×0.5 | 640 | 350 | 248000 | 460
Four-fluorinated polyether ring, with a diameter of 15mm, height of 15mm, and thickness of 0.5mm, boasts a surface area-to-volume ratio of approximately 640 square meters per cubic meter and an empty space volume fraction of around 35%. It has a packing density amounting to about two hundred forty-eight thousand particles per cubic meter. The packing coefficient is roughly equal to four hundred sixty.
Similarly,
Four-fluorinated polyether ring with dimensions measuring twenty-five millimeters in width by eight millimeters in height exhibits a surface area-to-volume ratio (alpha) at around five seventy square meters per cubic meter and an empty space volume fraction (epsilon) close to twenty-two percent. The packing density for this particular model comes out to be fifty-six thousand particles per cubic meter while the corresponding packing coefficient is approximately three ninety.
Another variation features dimensions thirty-five millimeters wide by one centimeter high; it shows up on the charts with an alpha value that stands at about four-thirty square meters per cubic meter as well as epsilon coming in at fifteen percent or so. In terms of packing efficiency, this specific type houses nineteen-thousand individual particles within each unit volume (m³), resulting in an overall filling factor equivalent to one-ninety units when compared against its respective epsilon value cubed.
Lastly,
fifty-millimeter-wide rings stacked twelve point five millimeters tall display their properties: alpha equals approximately four hundred square meters divided by each unit volume; epsilon measures eleven percent; packed particle count totals seven thousand items within every single volumetric unit; the resultant filling factor reaches thirteen units upon comparison against its own epsilon raised to the third power.
For those larger models like seventy-six-point-seveneen-millimeter-diameter cylinders sixteenth-of-a-meter tall—featuring properties such as alpha being almost eighteen-seventy square meters divided into every given cube size plus an emptiness percentage known as eighty—packing efficiency manifests through accommodating nearly two-thousand-one-hundred-and-seventy distinct objects inside these cubes without any gaps remaining between them all together forming what we call "filling factor" which equals eighty units once we compare it with ε^(-1).
