style="font-size:14px;">1、天然橡膠襯里類：天然橡膠襯里大多數(shù)用于濃酸類的防腐蝕保護(hù)，但是根據(jù)不同工況又有所區(qū)別。例如鹽酸，在溫度，昆明鋼襯膠廠家、濃度、儲(chǔ)存或運(yùn)輸?shù)炔煌闆r下，EMIR®鹽酸橡膠襯里有六種天然橡膠可用于上述不同鹽酸工況。此外，在固體幾何形物料的極度惡劣的磨損環(huán)境中，天然橡膠依然可以提供超卓的保護(hù)性能。</span> </p> <p> <span style="font-size:14px;">2、合成橡膠襯里類：比如丁橡膠襯里、丁基橡膠襯里、丁苯橡膠襯里等。丁基橡膠具有良好的耐化學(xué)性和耐氣候性，一般情況下的耐溫度為100℃，昆明鋼襯膠廠家，EV61HT氯丁基橡膠蕞高可耐溫127℃；丁苯橡膠大多數(shù)用于滑動(dòng)沖擊環(huán)境，耐磨損性優(yōu)異，工作溫度蕞高88℃；氯丁橡膠用于一般磨損和化學(xué)腐蝕環(huán)境，工作溫度蕞高99℃。</span> </p> <p> <span style="font-size:14px;">3、工程橡膠襯里類：比如乙丙橡膠、腈類橡膠。乙丙橡膠主要應(yīng)用于氧化性溶液和高溫環(huán)境，昆明鋼襯膠廠家，耐熱性、耐氣候性和耐臭氧性十分優(yōu)異。丙烯腈橡膠主要用于石油工藝環(huán)境，用于蕞高溫度88℃。氫化丁腈橡膠用于石油環(huán)境下的極端工藝條件，EV738橡膠可用于蕞高150℃的高溫環(huán)境。

域。如化學(xué)工業(yè)的鋼及水泥表面防腐中已應(yīng)用幾十年了。橡膠襯里用于燃燒無(wú)煙煤電廠的表面防護(hù)已十幾年，對(duì)于燃燒褐煤也有8年了。絕大部分橡腔襯里是在現(xiàn)場(chǎng)完成的，管道一般在車間內(nèi)襯膠。由于特殊工藝條件以及應(yīng)用技術(shù)方面的原因，原材料尤其是橡膠種類的選擇是至關(guān)重要的。橡膠村里在FGD裝置中承受著各種負(fù)荷。無(wú)煙煤電廠的 FGD裝置中橡膠村里的工作溫度為45～55℃，</span><span style="font-size:14px;">明顯低于褐煤電站的溫度 (60～ 68℃)。在FGD裝置吸收塔內(nèi)。懸浮液主要含石灰石，還有亞硫酸鹽、氯化物等溶解鹽。此外，還有SO2、HCI、NO及其它氣態(tài)物質(zhì)。懸浮液的pH值一般在4到6之間。除化學(xué)侵蝕外，吸收塔內(nèi)還有機(jī)械方面的負(fù)荷，尤其是懸浮固體引起的摩擦。在吸收塔頂部及清潔氣體排出管道內(nèi)，</span><span style="font-size:14px;">橡膠村重暴露于臺(tái)有殘余SO2、HCI、NO及其它物質(zhì)的水蒸汽中。由于水分子活性高，且存在一些氧化劑，F(xiàn)GD裝置的這些部位，特別是褐煤電廠，承受著相當(dāng)高的負(fù)荷。</span> 昆明哪家襯膠批發(fā)商好？昆明鋼襯膠廠家</p><p

（1）外觀檢查：檢測(cè)結(jié)果的判定是以對(duì)使用沒(méi)有影響為標(biāo)準(zhǔn)。</span> </p> <p> <span style="font-size:14px;"> （2）尺寸檢查：檢查的部位應(yīng)為設(shè)計(jì)圖紙、說(shuō)明書所指示的地方以及根據(jù)協(xié)議要求檢查的部位；塔槽、管道等的尺寸原則上不進(jìn)行測(cè)定；</span> </p> <p> <span style="font-size:14px;"> （3）硬度檢查：標(biāo)準(zhǔn)硬度以溫度為20C的測(cè)定值為基準(zhǔn)。硬質(zhì)膠、半硬質(zhì)膠及氯丁橡膠等因溫度而引起的硬度值變化較大，因此應(yīng)根據(jù)測(cè)定溫度，對(duì)照每種材質(zhì)的修正表?yè)Q算測(cè)定值，再作判定。邵氏彈簧式硬度計(jì)在測(cè)檢時(shí)在橡膠上會(huì)產(chǎn)生針的孔，因此應(yīng)在法蘭面或連接部位等即使產(chǎn)生針的孔也不會(huì)有影響襯層質(zhì)量的部位進(jìn)行測(cè)定。軟質(zhì)橡膠襯層在3mm以下時(shí)；由于受到襯底的影響，有時(shí)顯示較高的硬度值；</span> </p> <p> <span style="font-size:14px;"> （4）厚度檢查：厚度計(jì)有電磁式和永久磁鐵式，兩者都是利用磁力來(lái)測(cè)定鐵鉛合金上的橡膠厚度。襯膠的基體材料為非磁性金屬時(shí)不能測(cè)檢；有時(shí)在帶有殘留蒸汽的基材上及有強(qiáng)磁場(chǎng)的場(chǎng)合也不能測(cè)定。管徑較小的管道表面不能檢測(cè)，可在法蘭面上測(cè)定。</span> 昆明鋼襯膠廠家</p><p
