無(wú)硫/低硫柔性石墨卷材又稱柔性石墨紙或柔性石墨板材，是用天然鱗片石墨經(jīng)化學(xué)處理后，經(jīng)過(guò)加熱高溫膨化形成石墨蠕蟲(chóng)，這種像蠕蟲(chóng)一樣的石墨粉的密度約為0.003g/cc。然后經(jīng)滾壓形成柔性石墨卷材。 膨脹石墨卷材不含粘結(jié)劑和填充物，因此純度很高，具有良好的耐腐蝕性、耐放射性、 耐高/低溫、良好的壓縮回彈性、并具有自潤(rùn)滑性和不滲透性，適用于低壓部位的密封。石墨卷材和金屬薄板可以復(fù)合成多種形式的石墨復(fù)合板。

Sulfur free / low sulfur flexible graphite sheet, also known as flexible graphite paper or flexible graphite sheet, is made by the follow process: First natural flake graphite is deal with chemical treatment, then after heating in high temperature it takes in forms of graphite worms, the density is about 0.003 g/cc . Then after rolling it became flexible graphite sheet. Expandable graphite roll is without binder and filler, so the purity is high, with good corrosion resistance, radiation resistance, high / low temperature resistance, good compression resilience, and have the self lubrication and non permeability, suitable for low pressure parts of the sealling. The graphite sheet and the metal sheet can be combined to make various forms of graphite composite plates.

 

性能特點(diǎn)： Performance characteristics
1.優(yōu)異的耐熱性和耐寒性。柔性石墨從-270度的超低溫到3650度（在非氧化氣體中）的高溫，其物理性質(zhì)幾乎沒(méi)有什么變化，在空氣中也可以使用到450度左右；

Excellent heat resistance and cold resistance. From ultra-low temperature of -270 degrees to 3650 degrees (in non oxidizing gas) of high temperature, the physical properties has almost no change, in the air , it can also be used 450 degrees.
2.優(yōu)異的耐化學(xué)腐蝕性。柔性石墨除在王水、濃硝酸、濃硫酸、高溫重鉻酸鹽、高錳酸鉀、氯化鐵等強(qiáng)氧化性介質(zhì)中有腐蝕外，幾乎對(duì)一切無(wú)機(jī)及有機(jī)介質(zhì)都耐腐蝕；
   Excellent chemical resistance. Flexible graphite were corrosive in Strong oxidizing medium such as aqua regia, concentrated nitric acid and concentrated and high temperature dichromate, Potassium Permanganate, ferric chloride, Corrosion resistant to almost all inorganic and organic media.

3.良好的自潤(rùn)滑性。柔性石墨同天然石墨一樣，層間在外力作用下，容易產(chǎn)生滑動(dòng)，因而具有潤(rùn)滑性，有較好的減磨性，摩擦系數(shù)?。?

Good self lubrication. The same as natural graphite, the flexible graphite is easy to slide under the action of external force, so it has the property of lubrication, good abrasion resistance and small friction coefficient;

4.回彈率高。當(dāng)軸或軸套因制造、安裝等因素存在偏離而出現(xiàn)徑向圓跳動(dòng)時(shí)，具有足夠的浮動(dòng)性能，即使石墨出現(xiàn)裂紋，也能很好密合，從而保證貼合緊密，防止泄漏。

High rebound rate. When the shaft or sleeve has a deviation and radial runout for manufacturing, installation problems, it has sufficient floating performance, even if the graphite cracks, it can close together, thus ensuring closeness and preventing leakage.
