池州耐火保溫漂珠 發(fā)熱冒口漂珠 20-300目空心漂珠 低密度高鋁含量漂珠廠家批發(fā) 、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(SiO2)約為50-65%,三氧化二鋁(Al2O3)約為25-35%。因?yàn)槎趸瑁⊿iO2)的溶點(diǎn)高達(dá)1725攝氏度,三氧化二鋁(Al2O3)的溶點(diǎn)為2050攝氏度,均為高耐火物質(zhì)。因此,漂珠具有的耐火度,一般達(dá)1600-1700攝氏度,使其成為的耐火材料。一顆顆還沒(méi)熟透的果實(shí)仰著或紫或綠的小臉兒,對(duì)著老人笑呢。

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250-450kg/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)。 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 of 2.10 2.20 g/cm3, therefore, drift beads with high strength.General light porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or light refractory products, intensity difference flaws.The advantages of their shortcomings is drift beads, so drift beads have more competitive advantages, used more widely.
4, excellent electrical insulation, non-conductive: choose after degaussing beads drift beads, is the performance of insulation materials我固執(zhí)地相信它的簡(jiǎn)單它的純美就好了,無(wú)需解釋太多,也解釋不了太多。
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(lái)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2.10-2.20g/cm3,因此,漂珠具有很高的強(qiáng)度。一般輕質(zhì)多孔或中空材料如珍珠巖、沸巖、硅藻土、海浮石、膨脹蛭石等均是硬度差、強(qiáng)度差,用其制的保溫隔熱制品或輕質(zhì)耐火制品,都有強(qiáng)度差的缺點(diǎn)。他們的短處恰恰是漂珠的長(zhǎng)處,所以漂珠就更有競(jìng)爭(zhēng)優(yōu)勢(shì),用途更廣。

Drift beads characteristics
1, high refractoriness, the main chemical compositions for silicon drift beads, aluminum oxide, silica (SiO2) about 50-65%, 3 oxidation 2 aluminium (Al2O3) about 25-35%.Because the melting point of silica (SiO2) is as high as 1725 degrees Celsius, 3 oxidation 2 aluminium (Al2O3), the melting point of 2050 degrees Celsius, are all high refractory material.Therefore, drift beads have high refractoriness, generally 1600-1600 degrees Celsius, make its excellent high performance refractories.
2, 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純色,或花色各種,都是棉麻布料。待要出門時(shí),便打開(kāi)衣柜從左至右,挑選出一條與上衣相配的美美地穿上。 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 of 2.10 2.20 g/cm3, there
5、粒度細(xì),比表面積大:漂珠自然形成的粒度為1-250微米。比表面積300-360g/cm2,和水泥差不多。因此,漂珠不需粉磨,可直接使用。細(xì)度可滿足各種制品的需要,其他輕質(zhì)保溫材料一般粒度都很大(如珍珠巖等),如果粉磨就會(huì)大幅度增加容量,使隔熱性大大降低。
