(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

電纜密封是密封技術(shù)中的一種特殊技術(shù)。它正處于不斷發(fā)展之中,并且越來越多地被應(yīng)用在生產(chǎn)、生活和軍事等方面,如大壩、電纜、地下建筑、過江穿海通道、潛艇、石油開采和船舶等多個(gè)領(lǐng)域。
通常,碳纖維增強(qiáng)聚氨醋(PU)復(fù)合丁基防水嵌縫膠是專門針對(duì)處于海洋環(huán)境中的電纜與密封殼體之間研制的一種新型材料,具有操作簡便、耐老化性能優(yōu)異等特點(diǎn)。碳纖維增強(qiáng)PU復(fù)合丁基防水嵌縫膠在壓縮強(qiáng)度達(dá)到7 MPa的條件下,其耐酸性、耐堿性和抗輻射性等明顯優(yōu)于目前常用的傳統(tǒng)密封填料。
我國在電纜與殼體密封的力學(xué)性能研究、密封材料在動(dòng)態(tài)壓力下的作用研究方面尚處于空白階段。本文擬將靜態(tài)力學(xué)中的某些計(jì)算方法和理論用于電纜環(huán)型管節(jié)丁基防水嵌縫膠強(qiáng)度的計(jì)算,并結(jié)合壓力試驗(yàn)過程及密封材料的破壞型式,對(duì)丁基防水嵌縫膠的密封性能進(jìn)行評(píng)價(jià)。
電纜密封強(qiáng)度指標(biāo)
軸向壓縮強(qiáng)度、環(huán)向拉伸強(qiáng)度和徑向壓縮強(qiáng)度均大于7 MPa。
①應(yīng)用復(fù)合材料層合板理論,將強(qiáng)度指標(biāo)視為相同壓力值施加于殼體上,計(jì)算出殼體材料的軸向(Z)和環(huán)向(e>材料彈性常數(shù);②根據(jù)應(yīng)力和彈性常數(shù)計(jì)算殼體的軸向(Z)和環(huán)向(0應(yīng)變;③根據(jù)殼體的軸向(Z)和環(huán)向(e>應(yīng)變,計(jì)算殼體材料的軸向和環(huán)向應(yīng)力;④將殼體材料所受應(yīng)力與單向板的材料強(qiáng)度進(jìn)行比較,按照線彈性理論(應(yīng)力與應(yīng)變成比例),得出殼體材料與單向板的材料強(qiáng)度成比例,從而按比例關(guān)系反推出殼體強(qiáng)度。http://www.caffertyclinic.com/
