770PF PEEK 吉林中研高塑 总代理直销
吉林中研高塑770PF PEEK产品介绍:
中研股份770P主要采用亲核高温置换反应的制备方法来制备PEEK原料。以对苯二酚和4,4′-二氟二苯酮为基础原料,采用高沸点的惰性溶剂,加入中研股份自行研发的催化剂配方,经过高温缩聚反应制备成高性能PEEK树脂。
中研股份聚醚醚酮(PEEK)树脂,运用气流涡旋粉碎工艺制得不同目数的聚醚醚酮(PEEK)纯树脂超细粉系列产品;运用柱式叠网超微过滤方法制得聚醚醚酮(PEEK)纯树脂颗粒;与耐高温结构材料和电绝缘材料进行复合改性,生产出各种牌号的复合改性专用料。
吉林中研高塑770PF PEEK特性:
PEEK塑胶原料具有优越的尺寸稳定特性,这对某些应用来说有的很重要。温度、湿度等环境条件的变化对PEEK零件
的尺寸影响不大,可以满足对尺寸精度要求比较高工况下的使用要求。
1.PEEK塑胶原料注塑成型收缩率小,这对控制PEEK注塑零件的尺寸公差范围非常有好处,使PEEK零件的尺寸精度比通用塑料高很多;
2. 热膨胀系数小,随着温度的变化(可由环境温度的变化或运转过程中摩擦生热引起),PEEK零件的尺寸变化很
小;
3.PEEK耐热水解特性突出,在高温高湿环境下吸水性很低,不会出现类似尼龙等通用塑料因吸水而使尺寸发生明显
变化的情况;
吉林中研高塑770PF PEEK详解:
In this paper, we argued the necessity of making explicit thetie between secu-rity requirements and the organization’s business drivers. A company like Googlethat is making profit with online advertising would tend to keep its search engineavailability as high as possible, without taking too much care about data confi-dentiality (thus is, they are public available with few clicks). On the other hand,a financial entity that offers online servicing would be more focused on dataconfidentiality than availability because possible legal acts brought by damagedusers could cost more than a temporary service shutdown. Thedifference is de-termined by the underlying different business drivers the different organizationshave.Further we proposed a conceptual framework to that aim. Three main ele-ments are included in the framework, namely, business vision, CIFs and valuableassets and their security requirements. The connection between business goalsand security requirements, once established, can be used toprovide rational forprioritizing security requirements. A number of issues need future work.免责声明:当前页为 PEEK 770PF 吉林中研高塑 韧性好产品信息展示页,该页所展示的 PEEK 770PF 吉林中研高塑 韧性好产品信息及价格等相关信息均有企业自行发布与提供, PEEK 770PF 吉林中研高塑 韧性好产品真实性、准确性、合法性由店铺所有企业完全负责。世界工厂网对此不承担任何保证责任,亦不涉及用户间因交易而产生的法律关系及法律纠纷,纠纷由会员自行协商解决。
