首个由中国企业主导 豫企制定的纳米金刚石国际标准发布
He Nan Ri Bao· 2025-07-11 23:21
7月10日,记者从河南联合精密材料股份有限公司获悉,由该公司主持制定的纳米金刚石国际标准 ISO6031 : 2025 《 ISO6031 : 2025Functionalextendersforspecialapplication— Nanoscalediamondsforpolymercomposites》日前正式由国际标准化组织(ISO)向全球发布。这是金刚石 领域首个由中国企业主持制定的国际标准,标志着我国超硬材料企业在国际标准领域实现了从"跟 随"到"引领"的跨越。 纳米金刚石被誉为材料界的"工业味精",具有超强硬度、卓越导热性、极佳耐磨性以及独特的表面化学 特性,在提升聚合物复合材料的强度、韧性、耐磨、导热、减摩等关键性能方面展现出巨大潜力,被广 泛应用于航空航天、精密电子、医疗器械、新能源汽车等高端领域。 长期以来,在纳米金刚石的生产工艺、表面功能化处理以及最终的复合材料性能评价等方面,全球缺乏 统一、科学、可比的规范。标准的缺失,制约了该技术的产业化进程和市场规范化发展。 河南联合精密材料股份有限公司作为我国纳米金刚石材料领域的"隐形冠军",多年来持续专注纳米微米 金刚石产品的深度研究、原始创 ...
重启上市路,海明润A股江湖十年再见!深创投加持,剑指北交所!

Core Viewpoint - Shenzhen Haimingrun Superhard Materials Co., Ltd. (referred to as "Haijingrun") is attempting to return to the A-share market after nearly a decade since its last IPO attempt, with a deadline to complete the listing by the end of 2026 to avoid potential buyback requests from investors [2][3][8]. Group 1: Company Background and Previous IPO Attempts - Established in August 2000, Haijingrun specializes in the research, development, manufacturing, and sales of polycrystalline diamond composite sheets (PDC) and other superhard materials, primarily focusing on oil and gas drilling tools [3][4]. - In June 2015, Haijingrun submitted its IPO application for the ChiNext board but withdrew it in August 2016 after facing significant operational challenges due to declining oil prices, which led to a sharp drop in revenue and profits [5][6][11]. - The company reported revenues of 188.44 million, 202.74 million, and 136.25 million from 2013 to 2015, with net profits of 36.36 million, 42.63 million, and 23.28 million respectively, and a net profit of less than 5 million in the first half of 2016 [5][6]. Group 2: Current Financial Status and Future Plans - As of 2023, Haijingrun's revenue reached 256.6 million, with a net profit of 46.34 million, indicating a recovery to levels similar to those in 2013 [6][8]. - In 2024, the company achieved a revenue of 291 million and a net profit of 57.69 million, but still fell short of the new listing requirements for the ChiNext board, which now mandates a net profit of at least 60 million in the most recent year [7][8]. - Haijingrun has submitted an application for listing on the New Third Board and aims to transition to the Beijing Stock Exchange, which is seen as the only viable option for a quick A-share listing [2][8]. Group 3: Risks and Challenges - The company faces significant time constraints and operational challenges to meet the listing deadline by the end of 2026, as it must be listed on the New Third Board for at least 12 months before applying for the Beijing Stock Exchange [8][9]. - Haijingrun's reliance on a limited number of clients remains a concern, with its largest client, National Oilwell Varco, contributing 38.22% and 41.08% of its revenue in 2023 and 2024, respectively [11][13]. - The company has acknowledged the risks associated with fluctuating oil and gas prices, which previously led to its IPO failure, and continues to face challenges in diversifying its product offerings beyond PDC products [14][15].
压力太大,氢会“方”吗

压力太大,氢会"方"吗 半月谈记者 张漫子 "压力太大,我方了"——人真的能变"方"吗?当然不至于。这句"网言网语",形容的是网友在压力之下 心情变化大,与日常判若两人。有谁愿意想一想,自然界中的元素,如果施以超强的高压,会发生怎样 根本性的变化? 科学家就很想拿氢来试一试。这种宇宙中最轻、最简单也最古老、最丰富的元素,在元素周期表上有个 略"尴尬"的位置——身在第一主族的它,身边的锂、钠、钾之类都是所谓碱金属,唯有它是非金属!氢 就永远不可能成为金属吗? 90年前,著名物理学家维格纳曾预言,极高压下,固态氢可以呈现出金属的性质。后来有人算了一下, 让氢金属化的压力得有500GPa(1GPa等于1万个大气压)——相当于一架停在针尖上的大型喷气式飞机 对针尖施加的力。 高压之下,氢到底会不会"方",彻底变成金属?最近,中国科学家发现了一点线索。 探测氢在高压下的结构转变,首先得有真正称得上"高压"的环境。科学家为此发明了一个"法宝"——金 刚石对顶砧。 氢"变形记" 5月14日,《自然》发表了一项北京高压科学研究中心毛河光院士团队的重大成果:凭借一种极特殊 的"显微镜"——X射线纳米探针,他们窥见了高压(212 ...

为何说半导体散热下一代材料或是金刚石
Zheng Quan Zhi Xing· 2025-07-02 08:09
有没有过手机烫到握不住、电脑风扇狂响却依然卡顿的烦躁?这些场景揭示了一个隐形瓶颈:芯片高速运转产生的热量,正成为解锁更强性能的"拦路虎"。 当传统散热手段触达天花板,科技巨头们不约而同转向了一种自然界的神奇材料——金刚石。 它不仅在珠宝柜台里闪耀,更悄悄潜入实验室,成为工程师们对抗高温的秘密武器。从降低20℃的GPU温度,到激增三倍的AI运算速度,金刚石散热正带来 突破性改变。这坚硬璀璨的"石头",为何被视作下一代半导体材料的风口? 国内产业链同样大放异彩:凭借占全球90%以上产量的规模化制造优势,中国的人造金刚石成本优势显著。化合积电等国内企业已提供完整的金刚石半导体 解决方案并实现规模量产(光莆股份(300632)为其股东)。2024年8月,我国对相关设备技术的出口管制进一步凸显其战略价值。 开源证券预测市场规模将呈爆发式增长——从2025年约0.5亿美元(渗透率不足0.1%),极速攀升至152亿美元(渗透率约10%),年复合增长率高达214%。一场 由金刚石引领的散热革命正在重塑整个电子产业的未来格局。 | 次11:我们刘丹 2025十钻石机热中物观展 U.5 亿美元, 2030千臂衣王 152.4 亿 ...
