溫州耐火保溫漂珠 鑄造發(fā)熱冒口漂珠防火保溫涂料40-200目低密度高鋁含量漂珠多少錢(qián) 漂珠應(yīng)用于涂料、油漆中具有如下優(yōu)勢(shì)：

1.樹(shù)脂用量少/加量的潛力大：因?yàn)樵谌魏涡螤钪?，球形具有小的比表面積，漂珠對(duì)樹(shù)脂的需求量也少。顆粒的堆積情況也被改進(jìn)。漂珠的寬的粒徑分布使得小的微球能夠填充到大的微球之間的空隙中。其結(jié)果……實(shí)際上就是：高加入量、高固體含量、較低的VOC和減少其它成份的用量；

2.低粘度/改善流動(dòng)性：與不規(guī)則形狀的顆粒不同，漂珠很容易在彼此之間滾動(dòng)。這使得使用漂珠的體系具有較低的粘度，較好的流動(dòng)性。而且，體系的可噴涂性也得到改善；

3.硬度/耐磨性：漂珠是一種強(qiáng)度高，而且堅(jiān)硬的微球，它能增強(qiáng)涂料的硬度、耐洗刷性能和耐磨性；

4.優(yōu)良的隔熱效果：由于漂珠中空的球體結(jié)構(gòu)，使得的其填充于涂料中具有優(yōu)良的隔熱效果；

5.光澤控制：作為一種填料所起的作用，漂珠能降低光澤，用來(lái)控制洶涌，甚至在加入量要求較高的情況下，它們也能消除象普通的消光劑容易造成的粘度的大幅度增加，而且成本也低；

6.惰性：漂珠由惰性成份組成，因而具有優(yōu)良的經(jīng)久耐用性、耐侯性、耐腐蝕性和抗化學(xué)性能；
Drift beads characteristics
1, high refractoriness,The main chemical compositions for silicon drift beads, aluminum oxide, about 50-65% of silica, 3 oxidation 2 aluminium about 25-35%.Because the melting point of silicon dioxide as high as 1725 degrees Celsius, 3 oxidation 2 aluminium melting point of 2050 degrees Celsius, are all high refractory material.Drift beads, therefore, has a very high refractoriness, generally 1600-1600 degrees centigrade, making it a superior quality refractory materials.
為這事我和他冷戰(zhàn)了幾天，但是幾天之后我依然沒(méi)有看到新手機(jī)，我就想，會(huì)不會(huì)是他轉(zhuǎn)手賣(mài)了，于是就問(wèn)他，他說(shuō)沒(méi)有，手機(jī)就在同事那里，我責(zé)令他馬上把手機(jī)要回來(lái)，他上班臨走前我一再的叮囑，不拿手機(jī)回來(lái)就不要進(jìn)家門(mén)了
2, qualitative 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.
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 is 2.10 2.20 g/cm3, therefore, drift beads with high strength.買(mǎi)的房，房產(chǎn)證寫(xiě)著男方的名字；也與女方?jīng)]有任何關(guān)系

男方父母全款買(mǎi)下的房子，房產(chǎn)證上寫(xiě)了男方的名字。那還是與女方?jīng)]有關(guān)系，除非女方家長(zhǎng)也有出錢(qián)出力。畢竟，只要女
4, insulated non-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 is can make excellent insulation.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.
7.不透明性：漂珠的空心的球形使光線慢射和散射，其結(jié)果是增加了涂料的遮蓋力；

8.分散性：漂珠分散同礦物填料一樣，由于漂珠的厚壁和很高的抗壓強(qiáng)度，它能承受所有種類(lèi)的攪拌機(jī)、擠壓機(jī)及模塑機(jī)的加工過(guò)程；

9.無(wú)結(jié)晶硅污染：與其它的填料不同，漂珠中結(jié)晶硅的含量在無(wú)危害的水平以下。此類(lèi)漂珠不被看作致癌物質(zhì)，也不需要特別的危害警告標(biāo)志注明。

10.高固體工業(yè)涂料：低粘度、高加入量，減少VOC，改進(jìn)硬度，控制光澤，增加耐磨性、可噴涂性，降低成本；
