四川粉煤灰漂珠 铸造冒口漂珠 保温涂料添加低密度细漂珠价格多少钱20-100目漂珠报价 漂珠是一种能浮于水面的粉煤灰空心球，呈灰白色，壁薄中空，重量轻，容重为250－450kg/m3，粒径约0.1毫米，表面封闭而光滑，热导率小，耐火度≥1700℃，是优良的保温耐火材料，广泛用于轻质浇注料的生产和石油钻井方面。漂珠的化学成份以二氧化硅和三氧化二铝为主，具有颗粒细、中空、质轻、高强、耐磨、耐高温、保温绝缘、绝缘阻燃等多种功能，现已广泛应用于各个行业。

漂珠特性
1、高耐火度；漂珠的主要化学成分为硅、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,只有极微量的气体（N2、H2及CO2等），热传导极慢极微。所以漂珠不但质轻（容重250－450公斤/m3），而且保温隔热（导热系数常温0.08－0.1），这为其在轻质保温隔热材料领域大显身手奠定了基础。
3、硬度大、强度高；由于漂珠是以硅铝氧化物矿物相（石英和莫来石）形成的坚硬玻璃体，硬度可达莫氏6－7级，静压强度高达70－140MPa，真密度2.10－2.20克/cm3，因此，漂珠具有很高的强度。
4、绝缘不导电；一般绝缘体的电阻均随温度的升高而降低，漂珠则相反，随温度的升高电阻增大。这一优点是其他绝缘材料都不具备的。所以，它可以制作是性能优
