莆田耐火保溫板材添加料漂珠 電廠漂珠 冒口漂珠 鑄造冒口漂珠報價多少錢一噸 空心漂珠 漂珠是一種能浮于水面的粉煤灰空心球,呈灰白色,壁薄中空,重量輕,容重為250-450kg/m3,粒徑約0.1毫米,表面封閉而光滑,熱導(dǎo)率小,耐火度≥1700℃,是優(yōu)良的保溫耐火材料,廣泛用于輕質(zhì)澆注料的生產(chǎn)和石油鉆井方面。漂珠的化學(xué)成份以二氧跳上他的背,讓他背著走。如果他有外心,小獸一樣撲過去撕打他。如果他留下來,那么他是愛你的;如果他走掉,那就不要再記起他。雖然這樣極端,但是不能委屈自己,也不委屈愛情。
3、深情之壞:在他勞累時、苦悶時、高興時、失意時擁他入懷,像個壞壞的有著大男人主義的小女人;在自己勞累時、苦悶時、高興時、失意時投入他的懷抱,像個弱小無助的小女人。在他疑惑時迷茫時一定要深情地對視,然后告訴他,你愛他支持他,哪怕你覺得他是為了一個不那么成問題的事情而疑惑或迷茫?;韬腿趸X為主,具有顆粒細(xì)、中空、質(zhì)輕、高強、耐磨、耐高溫、保溫絕緣、絕緣阻燃等多種功能,現(xiàn)已廣泛應(yīng)用于各個行業(yè)。
us, 3 oxidation 2 aluminium melting point of 2050 degrees Celsius, are all high refractory material.Drift beads, therefore, has a very high refractoriness, generally 1600-1600 degrees centigrade, making it a superior quality refractory materials.
2, qualitative light, heat preservation and heat insulation;Drift beads thin wall hollow, empty cavity for half a vacuum, only trace amounts of the gas (N2 and H2 and CO2, etc.), heat transfer is very slow.So drift beads not only light (250-450 kg/m3 density), excellent heat preservation and heat insulation and thermal conductivity at room temperature (0.08-0.1), which play a prominent role in the field of lightweight thermal insulation material for its laid a solid foundation.
3, high hardness, high strength;Because of drift beads on silicon aluminum oxide mineral phases (quartz and mullite) formation of hard vitreous, hardness of Morse 6-7, hydrostatic strength up to 70-140 mpa, true density is 2.10 2.20 g/cm3, therefore, drift beads with high strength.
4, insulated non-conductive;Insulation resistance are commonly by the rise of temperature, drift beads, on the other hand, increases with the increase of temperature resistance.This advantage is don't have other insulating materials.So, it is can make excellent insulation.5, particle size, specific surface area;Drift beads natural formation of the particle size of 1-250 microns.Specific surface area of 300-360 - g/cm2, and cement.Therefore, drift beads without grinding, can be used directly.Fineness can meet the needs of a variety of products.
漂珠特性
1、高耐火度;漂珠的主要化學(xué)成分為硅、鋁的氧化物,其中二氧化硅約為50-65%,三氧化二鋁約為25-35%。因為二氧化硅的溶點高達(dá)攝氏1725度,三氧化二鋁的溶點為攝氏2050度,均為高耐火物質(zhì)。因此,漂珠具有的耐火度,一般達(dá)攝氏1600-1700度,使其成為的耐火材料。
2、 質(zhì)輕、保溫隔熱;漂珠壁薄中空,空腔內(nèi)為半真空,只有極微量的氣體(N2、H2及CO2等),熱傳導(dǎo)極慢極微。所以漂珠不但質(zhì)輕(容重250-450公斤/m3),而且保溫隔熱(導(dǎo)熱系數(shù)常溫0.08-0.1),這為其在輕質(zhì)保溫隔熱材料領(lǐng)域大顯身手奠定了基礎(chǔ)。
3、硬度大、強度高;由于漂珠是以硅鋁氧化物礦物相(石英和莫來石)形成的堅硬玻璃體,硬度可達(dá)莫氏6-7級,靜壓強度高達(dá)70-140MPa,真密度2.10-2.20克/cm3,因此,漂珠具有很高的強度。
4、絕緣不導(dǎo)電;一般絕緣體的電阻均隨溫度的
