一、節(jié)能、隔音

的導(dǎo)熱系數(shù)為0.325w/m.k，大約是粘土瓦的1/3，10mm厚水泥瓦的1/5，0.5mm厚彩鋼瓦的1/2000。在不考慮加保溫層的情況下，瓦的保溫性能仍能達到。通過音位測定實驗表明，在遭受、冰雹、大風(fēng)等外界影響時，瓦都能很好的吸收噪音。

二、抗沖擊耐低溫效果好

1公斤重的鋼球自1.5米高度自由落在瓦面上不產(chǎn)生裂紋。經(jīng)過10個冷凍循環(huán)，瓦無空鼓、氣泡、剝離、裂紋現(xiàn)象。

三、色彩

該即使長期暴露于紫外線、濕氣、熱、寒和沖擊下，仍能保持其顏色的穩(wěn)定性。通過國家化學(xué)建筑材料測試中心12000小時的人工老化測試，檢測結(jié)果△E=2.86。

四、的抗荷載

通過國家化學(xué)建筑材料及構(gòu)件質(zhì)量監(jiān)督站檢測，在支撐間隔750mm情況下，加重150kg，產(chǎn)品沒有被破壞。

五、的自防水性能

所選用的高耐候性樹脂本身致密且不吸水，不存在微孔滲水的問題。的單張面積大，屋面接縫少，搭接處結(jié)合嚴密，可以省去防水層。

六、質(zhì)量輕

每平方米重6.1kg是一種輕質(zhì)材料。無需加裝過多鋼結(jié)構(gòu)，對墻體、地基承重要求小。

七、自清潔

該產(chǎn)品本身不宜吸附灰塵，一經(jīng)雨水沖刷便潔凈如新，不會出現(xiàn)積垢后被沖刷的斑斑駁駁的現(xiàn)象。

八、優(yōu)異的耐腐蝕性能

該產(chǎn)品可以長期抵御酸、堿、鹽等各種化學(xué)物質(zhì)腐蝕，不會被雨雪侵蝕導(dǎo)致性能下降。

九、耐火性強

該產(chǎn)品主體樹脂屬難燃產(chǎn)品，經(jīng)國家防火部門檢測防火性能達到B1級。

十、體積穩(wěn)定

的膨脹系數(shù)為4.93×10-5(1/℃)，并在幾何形狀設(shè)計上具有雙向拉伸性能，即使溫度變化很大，瓦的伸縮也能被自身消化，確保瓦的幾何尺寸穩(wěn)定。

十一、絕緣

該產(chǎn)品的另一個技術(shù)特性是不導(dǎo)電，遇到意外放電也會完好無損。

十二、安裝簡單

該產(chǎn)品只需用螺釘固定在鋼檀上，再輔以主脊，斜脊等配件，便可經(jīng)久耐用，使用壽命長達35年以上。

現(xiàn)象：男人和女人，當(dāng)他們從所有錯誤的感覺和厭惡中解放出來，發(fā)現(xiàn)彼此不是對立的而是兄弟姐妹和鄰居，是一個完整的人類，他們將簡單地、認真地，耐心地共同忍受那置于他們身上的沉重的性。

對許多人來說，什么事都可能發(fā)生。孤獨的人現(xiàn)在已能開始營造，用自己的手，而且犯極少的錯誤。因此，親愛的先生，熱愛您的孤獨并且試著去歌頌?zāi)莿?chuàng)造了您的痛苦。為了那些曾經(jīng)與您如此親密的東西的遠離，您寫作，這表明您周圍的空間已經(jīng)開始長大了。如果曾經(jīng)與您親密過的東西遠離了您，那么您廣闊的空間就已延伸到了星際，它太大了。為您自己的成長而感到高興吧。在這成長過程中別人是無法和您一起分享的，但您要溫柔地對待落后于您的人；在他們面前要自信和，不要讓他們因您的懷疑而感到苦惱，不要讓您的信念和快樂嚇壞他們，他們無法理解。找一些您能夠和他們分享的簡單而真實的感覺，那些不隨著您的變化一遍一遍地轉(zhuǎn)化的感覺；當(dāng)您看著他們，要愛那不是以您自己的形式而存在的生活，對那些逐漸變老的要保持寬容，他們害怕您所信賴的孤獨。避免為戲劇提供材料，它們總是在父母和孩子之間制造緊張氣氛，它耗干了孩子們的力量，浪費了長輩的愛，但是，即使他們不能達成理解，這力量和愛依舊在起著作用，在溫暖著人們。不要征詢他們的意見，不要期待任何理解；但是相信有一種愛會象遺傳一樣起來，相信這種愛的力量和祝福是如此強烈以至于您可以攜帶它旅行到天涯海角。

您要有一份職業(yè)了，這很好，您將獨立起來并成為完整的自己，從各個方面來說。耐心點等待，您將會知道那職業(yè)是否在多方面壓抑您的生活。我自己認為這是個艱難但非常興奮的過程，因為它負載著太多的慣例，個人擁有的自由發(fā)揮的空間實在是微乎其微。但是您的孤獨將支持您，將成為您的家，甚至在那不甚熟悉的環(huán)境里，在那兒您將發(fā)現(xiàn)自己的道路。我所有良好的祝愿都時刻伴隨著您，還有我的信念。

To say nothing of God. But the fear of the inexplicable has not only impoverished the reality of the individual; it has also narrowed the relationship between one human being and another, which has as it were been lifted out of the riverbed of infinite sibilities and set down in a fallow place on the bank, where nothing happens. For it is not only indolence that causes human relationships to be repeated from e to e with such unspeakable monotony and boredom; it is timidity before any new, inconceivable experience, which we dont think we can deal with. But only someone who is ready for everything, who doesnt exclude any experience, even the most incomprehensible, will live the relationship with another person as something alive and will himself sound the depths of his own being. For if we imagine this being of the individual as a larger or smaller room, it is obvious that most people come to know only one corner of their room, one spot near the window, one narrow strip on which they keep walking back and forth. In this way they have a certain security. And yet how much more human is the dangerous in security that his learning and squander it and apply it as a stimulant on the tired places of their lives and as a distraction rather than as a way of gathering themselves for their highest moments. People have even made eating into something else: necessity on the one hand, excess on the other; have muddied the clarity of this need, and all the deep, simple needs in which life renews itself have become just as muddy. But the individual can make them clear for himself and live them clearly (not the individual who is dependent, but the solitary man). He can remember that all beauty in animals and plants is a silent, enduring form of love and yearning, and he can see the animal, as he sees plants, patiently and willingly uniting and multiplying and growing, not out of physical pleasure, not out of physical pain, but bowing to necessities that are greater than pleasure and pain, and more powerful than will and withstanding. If only human beings could more humbly receive this mystery which the world is filled with, even in its smallest Things, could bear it, endure it, more solemnly, feel how terribly hey it is, instead of taking it lightly. If only they could be more reverent to ward their own fruitfulness, which is essentially one, whether it is manifested as mental or physical; for mental creation too arises from the physical, is of one nature with it and only like a softer, more enraptured and more eternal repetition of bodily delight. "The thought of being a creator, of engendering, of shaping" is nothing without its continuous great confirmation and embodiment in the world, nothing without the thousand-fold assent from Things and animals - and our enjoyment of it is so indescribably beautiful and rich only because it is full of inherited memories of the engendering and birthing of millions. In one creative thought a thousand forgotten nights of love come to life again and fill it with majesty and exaltation. And those who come together in the nights and are entwined in rocking delight perform a solemn task and gather sweetness, depth, and strength for the song of some future poet, who will appear in order to say ecstasies that are unsayable. And they call forth the future; and even if they have made a mistake and embrace blindly, the future comes anyway, a new human being arises, and on the foundation of the accident that seems to be accomplished here, there awakens the law by which a strong, determined seed forces its way through to the egg cell that openly advances to meet it. Dont be confused by surfaces; in thedangers, we must try to love them. And if only we arrange our life in accordance with the principle which tells us that we must always trust in the difficult, then what now appears to us as the most alien will become our most intimate and trusted experience. How could we forget those ancient myths that stand at the beginning of all races, the myths about dragons that at the last moment are transformed into princesses? Perhaps all the dragons in our lives are p天的
