CVD管式爐使用注意事項(xiàng)：1.冷爐使用時(shí)，由于管式爐膛是冷的，須大量吸熱，所以低溫段升溫速率不易過(guò)快，各溫度段的升溫速率差別不易太大，設(shè)置升溫速率時(shí)應(yīng)充分考慮所燒結(jié)材料的物理化學(xué)性質(zhì)，以免出現(xiàn)噴料現(xiàn)象，污染爐管。2.定期檢查溫度控制系統(tǒng)的電器連接部分的接觸是否良好，應(yīng)特別注意加熱元件的各連接點(diǎn)的連接是否緊固。，要在120℃左右烘烤1小時(shí)，在300℃左右烘烤2小時(shí)后使用，以免造成爐膛開(kāi)裂。爐溫盡量不要超過(guò)額定溫度，以免損壞加熱元件及爐襯。禁止向爐膛內(nèi)直接灌注各種液體及溶解金屬，保持爐內(nèi)的清潔。4.爐膛若采用石英管，當(dāng)溫度高于1000℃時(shí)，石英管的高溫部分會(huì)出現(xiàn)不透明現(xiàn)象，這叫失透是連熔石英管的一個(gè)固有缺陷，屬正常現(xiàn)象。 </p><p style="text-indent:25px">pecvd管式爐煙囪和煙道：其作用是將爐膛的煙氣排入大氣中，cvd管式爐，內(nèi)部均用耐火和保溫材料襯里。為調(diào)節(jié)煙氣排除速度，還裝有可活動(dòng)擋板。煙氣流動(dòng)為上抽式的加熱爐煙囪安裝在對(duì)流室上部；煙氣流動(dòng)為下行式的加熱爐，煙囪安裝在爐側(cè)，并設(shè)有煙道。吹灰器：其主要作用是防止積灰，管式爐膛，盡量保持爐管表面始終干凈，pecvd管式爐，用以強(qiáng)化對(duì)流管的對(duì)流傳熱，管式爐，提高爐的熱效率。煉廠應(yīng)用的吹灰器有自動(dòng)伸縮式和固定旋轉(zhuǎn)式兩種。立式爐是真空爐的一種,是在在真空環(huán)境中加熱的一種設(shè)備。</p><div

PECVD工作原理是什么？PECVD技術(shù)是在低氣壓下，利用低bai溫等離子體在工藝腔體的陰極du上（即zhi樣品放置的托盤(pán)）產(chǎn)生輝光放電，利用輝光放電（或另加發(fā)熱體）使樣品升溫到預(yù)定的溫度，然后通入適量的工藝氣體，這些氣體經(jīng)一系列化學(xué)反應(yīng)和等離子體反應(yīng)，較終在樣品表面形成固態(tài)薄膜。其工藝原理示意圖如圖1所示。在反應(yīng)過(guò)程中，反應(yīng)氣體從進(jìn)氣口進(jìn)入爐腔，逐漸擴(kuò)散至樣品表面，在射頻源激發(fā)的電場(chǎng)作用下，反應(yīng)氣體分解成電子、離子和活性基團(tuán)等。這些分解物發(fā)生化學(xué)反應(yīng)，生成形成膜的初始成分和副反應(yīng)物，這些生成物以化學(xué)鍵的形式吸附到樣品表面，生成固態(tài)膜的晶核，晶核逐漸生長(zhǎng)成島狀物，島狀物繼續(xù)生長(zhǎng)成連續(xù)的薄膜。在薄膜生長(zhǎng)過(guò)程中，各種副產(chǎn)物從膜的表面逐漸脫離，在真空泵的作用下從出口排出。廣東CVD管式爐廠家</p></p><br
