將下面的兩段話翻譯成英語(yǔ),謝謝!實(shí)在是太著急了,坐等翻譯大神,金幣數(shù)要多少給多少 近年來(lái),隨著高分子材料被廣泛應(yīng)用,它的易燃性引起了人們普遍的關(guān)注,高聚物的阻燃研究成為人們?nèi)找骊P(guān)注的熱點(diǎn)。傳統(tǒng)的含鹵阻燃劑,在材料燃燒時(shí)產(chǎn)生大量煙霧,并且放出有毒氣體,為消防工作和及時(shí)的救護(hù)工作帶來(lái)諸多困難。如何得到無(wú)鹵、低煙、低毒的阻燃體系,是該領(lǐng)域研究的主要方向。目前我國(guó)的阻燃劑產(chǎn)品中,無(wú)機(jī)阻燃劑具有穩(wěn)定性好、低毒或無(wú)毒、貯存過(guò)程中不揮發(fā)不析出、原料來(lái)源豐富、價(jià)格低廉等許多優(yōu)點(diǎn),且兼具阻燃、填充雙重功能,對(duì)環(huán)境非常友好,是一類很有前途的阻燃劑。受到高度重視和普遍應(yīng)用,是成為阻燃劑市場(chǎng)的主流。 本文對(duì)紅磷進(jìn)行了細(xì)化、白度化處理,然后采用密胺對(duì)紅磷進(jìn)行包覆處理,與氫氧化鎂共混對(duì)PP進(jìn)行改性,通過(guò)正交試驗(yàn)研究不同配比的紅磷與氫氧化鎂對(duì)PP力學(xué)性能的影響及不同配比的阻燃性能。測(cè)試表明,紅磷細(xì)化、白度化處理效果良好達(dá)到預(yù)期效果。通過(guò)燃燒試驗(yàn)及力學(xué)試驗(yàn)表明,燃燒等級(jí)達(dá)到預(yù)期效果,改性后的紅磷對(duì)PP的力學(xué)性能影響有所減小。 |

| In recent years, as the polymer is widely used, its flammability has aroused widespread attention, the study of fire retardancy of polymer becomes the focus of increasing concern.Conventional halogen-containing flame retardants produces a lot of smoke and releases toxic gases when it burns which brings some difficulties for firefighting and rescue work. |

| How to get a halogen-free, low smoke, low toxicity flame-retardant system is the main direction of research in the field. At present, in our country's flame retardant products, inorganic flame retardant is a promising kind of flame retardants. Because they have good stability, low toxicity or nontoxic, nonvolatile storage without precipitation, abundant sources of raw materials, low prices, and many other advantages. They also have flame - retardant and filling double feature and they are very friendly to the environment. |
