四川粉煤灰漂珠 鑄造冒口漂珠 保溫涂料添加低密度細(xì)漂珠價(jià)格多少錢20-100目漂珠報(bào)價(jià) 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)成份以二氧化硅和三氧化二鋁為主，具有顆粒細(xì)、中空、質(zhì)輕、高強(qiáng)、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(gè)行業(yè)。

漂珠特性
1、高耐火度；漂珠的主要化學(xué)成分為硅、k, casting insulating riser, pipe insulation shell, fire insulation coating;
2, building materials; building decoration, high road paving, roofing waterproof thermal insulation coating, road engineering, modified asphalt, etc.
3, the oil industry; oil field cementing, pipeline anti-corrosion insulation, subsea oilfield;
4, insulation materials; plastic filler, high temperature and high pressure insulation activation.
5, coating, paint, ink, adhesives, camouflage coatings, insulation paint, anticorrosive paint, paint, resistance to high temperature fireproof paint, interior and exterior wall coating, thermal insulation coating, floor paint, automobile putty, putty, etc.;
6, space and space development; satellite, rocket, spacecraft surface composite materials, satellite fire protection layer, marine equipment, ships, deep-sea submarine, etc.;
7, the plastics industry; such as automotive trim, instrument panels, appliance housings, fan, sound box, lamp assembly, casting;
8, glass fiber reinforced plastic products: all kinds of glass fiber reinforced plastic products, artificial marble, glass fiber reinforced plastic ship, arts and crafts,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(qiáng)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(jiān)硬玻璃體，硬度可達(dá)莫氏6－7級(jí)，靜壓強(qiáng)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(qiáng)度。
4、絕緣不導(dǎo)電；一般絕緣體的電阻均隨溫度的升高而降低，漂珠則相反，隨溫度的升高電阻增大。這一優(yōu)點(diǎn)是其他絕緣材料都不具備的。所以，它可以制作是性能優(yōu)
