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 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.化工填料是填料塔中氣液接觸的通常零件,在非常多行業(yè)都采取普通,具備好的的耐熱耐酸效果,能耐除氫氟酸以外的各樣無(wú)機(jī)酸、有機(jī)酸及有機(jī)溶劑的腐化,可在各種高,低局勢(shì)采用,其效果的效果是決定填料塔操縱效果的主要緣由。
填料的種類(1)無(wú)機(jī)填料和有機(jī)填料①無(wú)機(jī)類填料無(wú)機(jī)類填料主要以天然礦物為原料經(jīng)過(guò)開(kāi)采、加工打造的顆粒狀填料,少數(shù)填料是經(jīng)過(guò)處置打造的。a.氧化硅及硅酸鹽。b.碳酸鹽及碳化物。
燃煤火力電廠在特殊燃燒條件下從粉煤灰中分選、提純而成的功能型材料。由于國(guó)家對(duì)環(huán)保的要求越來(lái)越高,電廠工藝逐漸改進(jìn),漂珠產(chǎn)品日趨減少,同時(shí),市場(chǎng)對(duì)漂珠的需求卻快速上升。為了滿足國(guó)內(nèi)
活性炭是一種優(yōu)良吸附劑,可以有效去除水體中多種有機(jī)污染物 。在美國(guó)等發(fā)達(dá)國(guó)家 ,活性炭吸附技術(shù)被廣泛用于水和廢水處理領(lǐng)域 。然而在中國(guó) ,活性炭并未普遍使用 。主要有三方面原因: (1)對(duì)于活性炭液相吸 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 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.
drift beads use
1, fire-resistant insulation materials, such as light sintered brick, light unburned brick, casting insulation riser, pipe insulation shell heat preservation and heat insulation, fire insulation paint, paste, composite insulation dry powder, light resistant glass fiber reinforced plastic.
2, building materials, building decoration, high-grade pavement materials, roof waterproof thermal insulation coating, road engineering, modified asphalt, etc.指標(biāo)。這些指標(biāo)誠(chéng)然都很重要 ,但它們沒(méi)有形成系統(tǒng)的簡(jiǎn)易選炭方法 。盡管苯酚 、碘 、亞甲蘭和丹寧酸這四種化合物與活性炭?jī)?nèi)孔徑有良好關(guān)聯(lián),是表征活性炭吸附性能的理想化合物 ,但目前對(duì)于以這四種化合物為依據(jù)的性能指標(biāo)的定義與
