打破美50年技術封鎖!中企造出核心部件,美提錢“緊急求購”被拒 – 有海水的地方就有中國人

虽然中国的综合实力有了很大的提升,但也有一定的国际影响力。然而,作为航天发展领域的后起之秀,我们被西方技术垄断,导致我们在科研上走了很多弯路。但幸运的是,随着时间的推移,我们不仅建造了国内的空间站,还完成了一系列的太空探索。就连美国也想尽办法垄断军事技术50年,冲到了世界领先地位。

打破美国50年的技术封锁!中国企业创造了核心部件,美国资金的“紧急购买”遭到拒绝 (图1)据悉,这项技术就是“密封圈”,主要用于密封机械零件,可以防止液体和气体泄漏,在宇宙飞船和火箭上应用最多。在核电领域,密封环是核心部件,可以保证核电厂系统不泄漏。当年只有美国和法国掌握了这项技术。其中,美国“密封圈”技术在全球市场占据主导地位。鉴于其技术优势,该国不断提高价格,赚取巨额利润。虽然其他国家很不满意,但在过去的50年里,他们想尽了一切办法来打破这种局面。没想到,后来宁波的一家小工厂开发了这项技术。

打破美国50年的技术封锁!中国企业创造了核心部件,美国资金的“紧急购买”遭到拒绝 (图2)值得一提的是,我国核电站使用的C型密封最初是从美国进口的。由于中国核电站的密封圈每年都需要更换,美国抓住机会,每年都在提价。后来跟宁波中国企业竞标秦山核电厂垫片不成功,说如果中国企业继续竞标,就停止给中国核电厂供货密封圈。在这种背景下,中国下定决心要自主研发自己的密封圈。

打破美国50年的技术封锁!中国企业创造了核心部件,美国资金的“紧急购买”遭到拒绝 (图3)努力是有回报的,宁波中国企业4年研发成功“C型密封圈”。不仅技术比美国先进很多,价格也比美国低。当时整个核电行业都震惊了。此后国外同类产品价格下降了70%,国产核密封圈在国际上站稳了脚跟。现在轮到美国着急了。毕竟挑战者号航天飞机在第10次飞行中因为密封圈爆炸,最终酿成了悲剧。因此,美国曾六次在中国为这项技术开出过高的价格,但都被我们拒绝了。

打破美国50年的技术封锁!中国企业创造了核心部件,美国资金的“紧急购买”遭到拒绝 (图4)这个消息一出来,瞬间点燃了网友们的讨论,那就是宁波公司不仅为竞标报了仇,还委婉地告诉了美国“被卡脖子”是什么感觉。当然,除了密封圈,中国并没有停止在其他领域的发展。在军事领域,我们不仅是拥有双航母的国家之一,还致力于核航母的研发。在芯片领域,经过7年的艰苦研究,中国现在拥有“世界上第一台分辨力最高的紫外超分辨光刻设备”。我国自主研发的案例也提醒了全世界,拳头才是硬道理!
