美國(guó)捆扎固定裝置制造商Click Bond公司選用了具有耐受高侵蝕性環(huán)境能力的VICTREX PEEK聚芳醚酮材料,開發(fā)出一種新型電纜扎帶,用在高溫應(yīng)用環(huán)境中捆扎和固定電線和電纜。在石油鉆探應(yīng)用以及衛(wèi)星和敏感性**系統(tǒng)等航天應(yīng)用領(lǐng)域,VICTREX PEEK電纜扎帶能夠提供快速、**和穩(wěn)定的電線和電纜管理方案。
Click Bond公司美中西部銷售經(jīng)理Richard Moore稱：“電線和電纜從飛機(jī)機(jī)身的一端延伸到另一端,或者環(huán)繞著電動(dòng)泵發(fā)動(dòng)機(jī),這些電線和電纜必須捆扎和固定,從而避免與熱源接觸或碰到尖銳的邊緣。對(duì)于大多數(shù)應(yīng)用而言,尼龍制成的電纜扎帶已經(jīng)足夠,但在石油鉆探設(shè)備等高溫應(yīng)用中,電纜扎帶用于把小捆電線固定在抽油管道上,尼龍電纜扎帶往往會(huì)熔化,從而妨礙抽吸設(shè)備的運(yùn)作。因此我們必須利用VICTREX PEEK材料的耐熱特性,為客戶提供能夠保持穩(wěn)定性的電纜扎帶。”
威克斯公司工業(yè)應(yīng)用全球市場(chǎng)策劃Andrew Ragan 解釋道：“在深度鉆探的情況下,溫度可能會(huì)達(dá)到200°C (392°F)。石油業(yè)界選用了VICTREX PEEK材料,因?yàn)樗?*能在如此苛刻環(huán)境中仍然表現(xiàn)良好的材料。VICTREX PEEK能夠耐受高達(dá)260°C (500°F) 的溫度,并具有**的耐受電流、輻射和化學(xué)侵蝕環(huán)境的能力。”
Moore稱,即使在高溫條件下,VICTREX PEEK在鹽水和原油中也具有極好的耐化學(xué)腐蝕性能。在長(zhǎng)時(shí)間置于高壓和高溫水中之后,它仍具有長(zhǎng)期的可靠???。
Ragan解釋說,VICTREX PEEK具有低吸濕性和低釋氣性能,因此特別適合航天應(yīng)用。他說：“低吸濕性可確保電纜扎帶的尺寸穩(wěn)定性,而且VICTREX PEEK不含鹵素成分,在燃燒過程中僅散發(fā)極少的煙霧和毒氣。”
Moore補(bǔ)充道：“經(jīng)久耐用是*重要的。VICTREX PEEK具有**的機(jī)械性能,其機(jī)械強(qiáng)度符合要求,使我們能夠模塑制造強(qiáng)度比尼龍部件高出許多的部件。這種電纜扎帶具有單件式、注射模塑成型結(jié)構(gòu),可提供*大的強(qiáng)度并具有固定不同尺寸線束的可調(diào)性。”
Moore 指出,磨損可能是電氣線纜的主要問題,尤其是在飛機(jī)上。他說：“如果線纜封裝在塑料涂層中,尼龍?jiān)鷰У募怃J邊緣容易使涂層發(fā)生磨損。但使用模塑VICTREX PEEK電纜扎帶則不會(huì)發(fā)生這種現(xiàn)象,因?yàn)閂ICTREX PEEK材料固有潤(rùn)滑性能,具有很高的耐磨損特性。”
The excellent performance of PEEK is well appropriate for the military, drilling, railway, offshore or automotive industry.
Featuring best mechanical and design properties, the outside serrated tie is ideal for installations under extreme environmental, mechanical or chemical condition.
Due to the outside serration PEEK Ties are minimising any indentation or damage to cable insulation. The contoured head takes up less space therefore usage in areas with space restrictions is ideal.
The high-quality material of PEEK Ties withstands temperatures from -55° C up to +260° C. Their chemical resistance, even against acid and gamma radiation is excellent. Furthermore the PEEK Ties are high abrasion resistant.
The design offers a good ratio weight to tensile strength. With as little as 4.5mm² strap cross-section it holds a tensile strength of 230N but needs only 6N insertion force.
PEEK Ties conjunct the mechanical performance and resistance to environmental influence of a metal tie with the ease of use of a polyamide cable tie.
