[求助]
求潤(rùn)色一段自己翻譯的小摘要，謝謝
|
|
原文：防毒面具、防毒衣、防毒手套、防毒靴套等隔絕式個(gè)體防護(hù)裝備的主要彈性體材料是丁基類橡膠，丁基類橡膠分子結(jié)構(gòu)中密集的側(cè)甲基可以有效限制化學(xué)毒劑的熱運(yùn)動(dòng)。但是，密集側(cè)甲基所產(chǎn)生的較大內(nèi)摩擦損耗將造成材料的回彈性能偏低，繼而給隔絕式個(gè)體防護(hù)裝備帶來(lái)不利影響。采用NR、Q、EPDM、BR等內(nèi)摩擦較小的膠種與丁基類橡膠共混可以提高材料的回彈性能，但同時(shí)也會(huì)犧牲部分阻隔性能。鑒于阻隔性能與化學(xué)毒劑在橡膠內(nèi)部的擴(kuò)散行為密切相關(guān)，因此，項(xiàng)目擬開(kāi)展化學(xué)毒劑在丁基類橡膠二元共混體系內(nèi)擴(kuò)散行為研究，將Fick第二定律論引入到化學(xué)毒劑在丁基類橡膠二元共混體系內(nèi)的擴(kuò)散過(guò)程，構(gòu)建一維非穩(wěn)態(tài)擴(kuò)散方程，并研究微觀形態(tài)結(jié)構(gòu)對(duì)擴(kuò)散行為的影響規(guī)律,以期為未來(lái)隔絕式個(gè)體防護(hù)裝備的選材設(shè)計(jì)提供必要的設(shè)計(jì)參數(shù)和理論依據(jù) 翻譯：The elastic materials mainly used in Isolated Individual Protective Equipments (IIPE) such as mask, overgarment, gloves and footwear were butyl rubber. Its high resistance derives from the dense side methyl groups on the backbones which can prevent the thermal motion of other small molecules effectively. However, great internal friction originated from the dense side methyl groups will result to poor resilience, and finally affect the properties of IIPE. Resilience of butyl rubber can be improved by blending with other rubbers such as NR, Q, EPDM and BR which have low internal friction, unfortunately, these rubbers would decrease the resistance of the blend unavoidably due to they offered rather low resistances to the penetration of chemical warfare. Since the resistance was strongly depended on the diffusion behavior of chemical warfare inside the rubber, Fick’s second law would be applied in the diffusion of chemical warfare in the butyl rubber blend, and established one dimension unsteady diffusion model in this work. The influence of morphology on its diffusion behavior was also investigated. The purpose of this project is to providing necessary parameters and theoretical basis for future material design of IIPE. 煩請(qǐng)達(dá)人給潤(rùn)色下英文翻譯，謝謝 |
