寧波保溫涂料漂珠 40目細(xì)漂珠廠家報價 耐火發(fā)熱冒口漂珠 treous, 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, 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 m
1、耐火保溫材料：如輕質(zhì)燒結(jié)耐火磚、輕質(zhì)免燒耐火磚、鑄造保溫冒口、管道保溫外殼、防火保溫涂料、保溫隔熱膏、復(fù)合隔熱干粉、輕質(zhì)保溫耐磨玻璃鋼。

2、建筑材料：建筑裝飾、路面鋪料、屋頂防水保溫涂層、道路工程、改性瀝青等。

3、石油工業(yè)：油田固井、管道防腐保溫、海底油田、漂浮裝置、油井鉆探泥漿減輕劑、石油天然氣輸送管道等方面。

4、絕緣材料：塑料活化填充劑、高溫高壓絕緣體等。

5、涂料工業(yè)：油漆、油墨，粘合劑、隱身涂料、絕緣漆、防腐漆、地坪漆、耐高溫防火漆、內(nèi)外墻涂料、保溫涂料、地板漆、汽車膩子、原子灰等。
aterials.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,
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%。因為二氧化硅（SiO2)的溶點高達(dá)1725攝氏度，三氧化二鋁(Al2O3)的溶點為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。

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2.1繚繞，鳥聲動人，四周原野陰森寂靜，草叢深處，蟲子交媾的悅耳聲音讓大地不停為之震顫，空氣里漂浮著一股股粘稠濕熱的味道。男孩就趴在地面上，看地上的一只螞蟻。很久了，他就這樣一直看著，看著，從出生的那日一直看到0-2.20g/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。他們的短處恰恰是漂珠的長處，所以漂珠就更有競爭優(yōu)勢，用途更廣。

4、電絕緣性，不導(dǎo)電：選去磁珠后的漂珠，是性能的絕緣材料 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,揮了起來，天上的白云，地上奔跑的野兔，還有野蘑菇，蟑螂，老鼠，蚯蚓，蟈蟈，金錢豹，都被我一筆一劃用心寫 etc.), if the grinding would significantly increase capacity, insulating the stays is reduced greatly.
drift beads use
