搪玻璃反应釜一般维修方法

时间:2017-11-02作者:舜甫科技 点击:
  搪玻璃反应釜既有通常金属设备的机械强度,又有玻璃的稳定性,在化工出产中被广泛应用。可是,由于搪玻璃本身材质的问题及运用过程中各种外力、应力作用及介质的腐蚀性、反应条件忽冷忽热、运送、运用等疑问,很容易造成珐琅面掉落、爆瓷和穿孔等现象,然后影响设备的正常运转。
 
  Glass lined reactor has the mechanical strength of common metal equipment and the stability of glass. It is widely used in chemical production. However, due to the use of force, and in the process of stress corrosion effect and medium, reaction conditions, transport and use is sometimes hot and sometimes cold glass lining material, it is easy to cause enamel surface falling, exploding porcelain and perforation phenomenon, and then influence the normal operation of equipment.
 
一、搪玻璃反应釜如何修补
 
  1、将损坏设备拆下送到出产厂家去,费时费工费用也高。
 
  如搪玻璃反应釜修复时间为30天,1台5000L反应釜修复费用约2万元,1台1000L容器修复费用约0.6万元,一个塔节修复费用约0.2万元。并且每复搪一次钢板的减薄量加大,强度也显着降低,通常正常的搪玻璃反应罐复搪不能超越三次,如大面积掉落或较大设备类如反应釜、塔节、贮罐等。
 
  细小损坏时没有必要整台设备更新,这就需要选用合适的修补法进行修补,不然就会使反应釜被釜里溶剂腐蚀,珐琅面的损坏会迅速扩展,并由此构成停产、安全事故及环境污染等不可估计的损失。
 
  2、用于搪玻璃设备及其零部件表面衬层部分损坏的修复。这种办法修复时间短,费用低。如用高分子修复材料(钛合金珐琅修补剂)修复搪玻璃设备的腐蚀、脱瓷、穿孔部位,一天即可完结,修补费用在100到1000元左右。
 
First.How to repair the glass lined reactor
 
  1. to remove the damaged equipment manufacturers, wasting time and labor costs are high.
 
  Such as glass lining reactor repair time is 30 days, 1 5000L reactor repair costs about 20 thousand yuan, 1 sets of 1000L container repair costs about 6 thousand yuan, a tower repair costs about 2 thousand yuan. Thinning and each one plate lining rehabilitation increased strength is also significantly reduced, the complex glass lined reactor can not exceed three times the normal lining normally, such as large or larger equipment such as drop reactor, tower section, storage tank and so on.
 
  Small damage is not necessary to update the equipment, which requires the selection of appropriate repair method to repair, otherwise it will make the reaction kettle by kettle in solvent corrosion, enamel surface damage will expand rapidly, and thus constitute the production, safety accidents and environmental pollution and other unpredictable losses.
 
  2. for glass lined equipment and parts surface lining layer damage repair. This method has the advantages of short repair time and low cost. Such as polymer repair materials (titanium alloy enamel repair agent) repair glass lining equipment corrosion, porcelain, perforation site, one day can be completed, repair costs between 100 to 1000 yuan.
 
二、搪玻璃反应釜修补详细操作方法
 
  1.表面处理
 
  这是获得修复成功的关键一步,确定好被修部位后,铲除蚀损部位的积附物,用锉、砂轮机或角磨机等东西将设备脱瓷或穿孔的部位整理洁净,表面上不应留有介质腐蚀的搪玻璃、铁屑,金属要漏出,并使其表面粗化,原则是"越毛糙越好"。
 
  2.清洗
 
  用清洗剂(丙酮或酒精)擦拭洁净需要修复的表面。清洗面积要大于修复表面,避免构成清洗表面再次污染。
 
  3.配胶
 
  国产系列搪玻璃修补剂为双组剂胶泥状:A为主料,B为固化剂。将主料和固化剂按照3:1的份额放在洁净的容器内充分拌和混溶(依据修正部位巨细分配恰当的胶量)。
 
  4.涂胶
 
  先将少数修补剂均匀涂改在设备需求修复的表面,涂胶时应尽量向一个方向移动并施以必定压力,边涂改边碾磨刮实,赶尽气泡,使空气分出,保证修正剂与设备表面密实触摸贴合。
 
  第一遍涂改完毕后,将剩下的修正剂涂改到设备修正部位,使其抵达所需求的标准尺寸。固化后需求机加工的,定要留出余量。
 
  5.固化
 
  用碘钨灯烘烤设备修正部位,通过6~12小时(依据环境温度而定)烘烤,可利用辨听击打声响来查看固化作用,修补剂固化后反应釜即可运用。
 
Second. The detailed operation method to repair two, glass lined reactor
 
  1. surface treatment
 
  This is a key step in the successful repair, repair parts was determined after product attachment of the eradication of corrosion sites, with a file, grinding machine or grinder and other things will take off equipment of porcelain or perforated parts clean, leaving medium corrosion of glass lined, iron should not be on the surface of the metal to escape, and the surface roughness, the principle is "the more coarse and better".
 
  2. cleaning
 
  With cleaning agent (acetone or alcohol) wipe clean to repair surface. The cleaning area is greater than the surface repair, avoids cleaning the surface pollution again.
 
  3. sizing agent
 
  Domestic series of glass lining repair agent is a pair of clay like agent: A as raw material, B as curing agent. The main ingredients and curing agent are placed in the clean container according to the share of 3:1, and the mixture is fully mixed and dissolved (according to the size of the modified parts to allocate the appropriate amount of glue).
 
  4. gluing
 
  The first few surface repair agent in uniform correction equipment needs repair, glue should try to move in one direction and impose a certain pressure, side edge grinding scraping correction, drive all the air out of the bubble, and to ensure the correction agent and compacting device surface touch.
 
  After the first correction, the remaining correction agent is modified to the equipment correction site to reach the required standard size. After curing the demand of machining, must set aside margin.
 
  5. curing
 
  Modified parts with iodine tungsten lamp baking equipment, by 6 to 12 hours (depending on the ambient temperature) can be used to bake, listening to the sound check hit the curing effect, repair agent after curing reaction kettle can be used.
