无锡耐火保温*珠 空心*珠 高铝含量耐高温30目*珠厂家

<*n style="font-family:simhei;font-size:18pt;">*珠特性<*n>
<*n style="font-size:12pt;">      1<*n style="font-family:宋体;">、高耐火度；*珠的主要化学成分为*的氧化物，其中二氧化硅约为<*n style="font-family:'times new roman';">50<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">65<*n style="font-family:宋体;">％，三氧化二铝约为<*n style="font-family:'times new roman';">25<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">35<*n style="font-family:宋体;">％。因为二氧化硅的溶点高达摄氏<*n style="font-family:'times new roman';">1725<*n style="font-family:宋体;">度，三氧化二铝的溶点为摄氏<*n style="font-family:'times new roman';">2050<*n style="font-family:宋体;">度，均为高耐火物质。因此，*珠具有****高的耐火度，一般达摄氏<*n style="font-family:'times new roman';">1600<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">1700<*n style="font-family:宋体;">度，使其成为优异的*耐火材料。

<*n style="font-size:12pt;">      2<*n style="font-family:宋体;">、 质轻、保温隔热；*珠壁薄中空，空腔内为半真空，只有****微量的气体（<*n style="font-family:'times new roman';">N2<*n style="font-family:宋体;">、<*n style="font-family:'times new roman';">H2<*n style="font-family:宋体;">及<*n style="font-family:'times new roman';">CO2<*n style="font-family:宋体;">等），热传导****慢****微。所以*珠不但质轻（容重<*n style="font-family:'times new roman';">250<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">450<*n style="font-family:宋体;">公斤<*n style="font-family:'times new roman';">/m3<*n style="font-family:宋体;">），而且保温隔热优异（导热系数常温<*n style="font-family:'times new roman';">0.08<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">0.1<*n style="font-family:宋体;">），这为其在轻质保温隔热材料领域大显身手奠定了基础。

<*n style="font-size:12pt;">      3<*n style="font-family:宋体;">、硬度大、强度高；由于*珠是以*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<*n style="font-family:'times new roman';">6<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">7<*n style="font-family:宋体;">级，静压强度高达<*n style="font-family:'times new roman';">70<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">140MPa<*n style="font-family:宋体;">，真密度<*n style="font-family:'times new roman';">2.10<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">2.20<*n style="font-family:宋体;">克<*n style="font-family:'times new roman';">/cm3<*n style="font-family:宋体;">，因此，*珠具有很高的强度。

<*n style="font-size:12pt;">      4<*n style="font-family:宋体;">、绝缘不导电；一般绝缘体的电阻均随温度的升高而降低，*珠则相反，随温度的升高电阻*。这一优点是其他绝缘材<*n style="background-color:#ffffff;color:#333333;">ulation materials;<*n style="background-color:#ffffff;color:#333333;">Such as light sintered brick, light unburned brick, casting insulation riser, pipe insulati*hell heat preservation and heat insulation, fire insulation paint, pa*m*ite insulation dry powder, light resistant glass fiber reinforced plastic.
<*n style="background-color:#ffffff;color:#333333;">2, c*truction materials;<*n style="background-color:#ffffff;color:#333333;">Building decoration, high-grade p*ement materials, roof waterproof thermal insulation coating, road engineering, modified asphalt, etc
<*n style="background-color:#ffffff;color:#333333;">3, the oil industry;<*n style="background-color:#ffffff;color:#333333;">, pipeline anticorrosion insulation, undersea oil field oil well cementing, floating device, the well drilling mud reducing age*il and gas pipelines, etc.
<*n style="background-color:#ffffff;color:#333333;">4, insulating materials;<*n style="background-color:#ffffff;color:#333333;">Plastic activation fillers, insulation of high temperature and high pressure, etc.
<*n style="background-color:#ffffff;color:#333333;">5, coatings industry;<*n style="background-color:#ffffff;color:#333333;">Stealth coating, paint, printing ink, adhesives, insulating paint, anti-corrosion paint, flat paint, high temperature resistant fire retardant paint, wall paint, insulation paint, floor paint, putty, putty, etc;
<*n style="background-color:#ffffff;color:#333333;">6, *ce and *ce development;<*n style="background-color:#ffffff;color:#333333;">Satellite, rocket, the *cecraft surface com*ites, satellite fire protection layer, Marine equipment, ships, deep-sea submarine, etc;
<*n style="background-color:#ffffff;color:#333333;">7, the plastic industry;<*n style="background-color:#ffffff;color:#333333;">Such as car accessories, instrument panel, home appliance shell, fan, speakers, always bearing of lamps and lanterns, castin*ear, structure, zippers, pipes, plates, etc.
<*n style="background-color:#ffffff;color:#333333;">8, glass fiber reinforced plastic products: all kinds of glass fiber reinforced plastic料都不具备的。所以，它可以制作是性能优异的绝缘材料。<*n style="font-family:'times new roman';">5<*n style="font-family:宋体;">、粒度细，比表面积大；*珠自然形成的粒度为<*n style="font-family:'times new roman';">1<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">250<*n style="font-family:宋体;">微米。比表面积<*n style="font-family:'times new roman';">300<*n style="font-family:宋体;">－<*n style="font-family:'times new roman';">360g/cm2<*n style="font-family:宋体;">，和水泥差不多。因此，*珠不需粉磨，可直接使用。细度可满足各种制品的需要。
