     搪瓷儲罐反應釜生產工藝,搪瓷燒制工藝及其燒結溫度，搪瓷燒制工藝是搪瓷設備廠家生產搪玻璃反應罐設備的重要工藝之一，而在搪瓷燒制過程中其燒結溫度的控制則是燒制工藝的重要工序，所以我們必須嚴格遵循搪瓷燒制工藝流程、按照燒制工藝的技術參數和操作要點，精心生產高質量搪瓷設備。 搪瓷燒制工藝流程 ：1、瓷釉制備：瓷釉是涂在金屬坯體上的玻璃態硅酸鹽或硼硅酸鹽涂層。要按坯體材料種類和制品性能的要求來確定瓷釉化學組成，要求準確稱量，充分混勻（干混,也可加5-15％的水,并制成小球）,在隔焰池窯、坩堝窯或回轉爐中熔化達一定均勻程度，經水淬、氣冷或熱壓成薄片(0.6-1.5mm)，然后研磨（用球磨機或氣流粉磨機）成干釉粉或加水制成釉漿。2、涂搪：將釉粉或釉漿均勻涂敷在金屬坯胎上，經燒成后再涂敷面釉。涂搪方法有浸漬、澆注、噴霧、灑粉法等。灑粉法是在灼熱底釉上灑上干的面釉粉，使涂搪和焙燒合二為一的操作。此外，還有靜電涂粉和電泳法涂搪等。搪瓷反應釜，搪玻璃設備，搪玻璃搪瓷設備搪玻璃反應罐，搪玻璃蒸鎦罐，搪玻璃微型反應罐，搪玻璃電加熱反應罐，搪玻璃貯罐，搪玻璃片式換熱器，搪玻璃雙錐型回轉真空干燥機

3、燒(shao)成：已涂(tu)搪瓷釉的(de)坯(pi)件置于(yu)箱式爐(lu)、轉盤爐(lu)或(huo)隧道爐(lu)中燒(shao)成。含密著劑的(de)硼硅酸鹽底釉，燒(shao)結溫(wen)度(du)約為(wei)(wei)880-930℃，為(wei)(wei)使(shi)其能在坯(pi)體表面形成氧(yang)化鐵(tie)層(ceng)，有利(li)于(yu)瓷層(ceng)同坯(pi)體（鋼材(cai)）良(liang)好密著，需采取氧(yang)化氣(qi)(qi)氛；面釉燒(shao)結溫(wen)度(du)略低，用銻(ti)乳(ru)濁色的(de)銻(ti)面釉為(wei)(wei)850-900℃，鈦面釉為(wei)(wei)820-860℃，為(wei)(wei)使(shi)面釉具有良(liang)好乳(ru)濁和(he)鮮(xian)艷色彩(cai)，并與底釉緊密結合，要嚴(yan)格控(kong)制燒(shao)成時間和(he)爐(lu)中氣(qi)(qi)氛，鑄鐵(tie)坯(pi)體若用銻(ti)釉和(he)鈦釉則對(dui)氣(qi)(qi)粉尤為(wei)(wei)敏感(gan)。
