重慶空心微珠 漂珠 發(fā)熱冒口漂珠 40-100目細(xì)漂珠廠家報(bào)價(jià)低密度耐高溫漂珠價(jià)格穩(wěn)定 【漂珠介紹】

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，顆粒細(xì)、重量輕，高強(qiáng)耐磨、表面封閉而光滑，熱導(dǎo)率小，耐火度高、保溫絕緣、應(yīng)力應(yīng)變均勻等多種功能，廣泛用于耐火、保溫材料的生產(chǎn)和在塑料、涂料、油漆油墨、陶瓷、封裝材料、地板膠、石油鉆探等領(lǐng)域作增強(qiáng)性填充料。能既有效地改善產(chǎn)品性能或施工效果，又明顯地降低生產(chǎn)成本，現(xiàn)已廣泛應(yīng)用于耐火材料的原料之中。

【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（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，漂珠具有的耐火幸福。
我問MIMI：“你怎么對男朋友的標(biāo)準(zhǔn)設(shè)得那么低，你不追求金錢，不追求顏值，只希望體驗(yàn)一段幸福美好的愛情，可是他們都不珍惜你度，一般達(dá)1600-1700攝氏度，使其成為的耐火材料。
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, 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 can make is performance under the condition of high temperature insulation products.
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, other lightweight insulation materials generally large particle size (e.g., perlite, etc.), if the grinding would significantly increase capacity, insulating the stays is reduced greatly.覺男人對她不錯(cuò)，每天晚上都會(huì)給她打電話，發(fā)短信，有空還會(huì)來她的城市邀請她看電影。慢慢地，MIMI習(xí)慣了男人的存在，以為這樣就可以幸福下去，以為等她畢業(yè)的時(shí)候就可以和他結(jié)婚。

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)。

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，靜壓強(qiáng)度高達(dá)70-140MPa，真密度2.10-2.20
