      水热合成反应釜工作原理和使用注意事项

      时间:2020-03-20作者:舜甫科技 点击:
        水热合成反应釜又叫高压消解罐,主要用于样品前处理消解重金属、农残、食品、淤泥、稀土、水产品、有机物等,是测定微量元素及痕量元素时消解样品的得力助手.它由不锈钢的钢套、釜盖、聚四氟乙烯内杯(内衬)、钢棒、不锈钢垫片(两片)构成~
       
        Hydrothermal synthesis reactor is also called high pressure digestion tank, mainly used for sample digestion and heavy metals, pesticides, food, water, mud, rare earth products, such as organic matter, is the assistant digestion determination of trace elements and trace elements. It consists of stainless steel sleeve, a kettle cover, Teflon inner cup (lining), steel rods, stainless steel gasket (two) form.
       
      一、水热合成反应釜工作原理
      One.The working principle of hydrothermal synthesis reactor:
       
        水热合成反应釜是在一定温度、压力条件下应用高温高压的水溶液使那些在大气条件下不溶或难溶的物质溶解,或反响生成该物质的溶解产物,经过控制溶液的温度差使产生对流以构成过饱和状态而析出生长晶体?捎糜谀擅鬃柿系闹票、化合物合成、晶体生长等方面,也能够用于小剂量的合成反响,是高校极常用的小型反响釜。
       
        Hydrothermal synthesis reactor is used in high temperature and high pressure aqueous solution under certain temperature and pressure so that the solubility in atmospheric conditions or dissolved substances dissolved, the reaction product of the material, through the temperature control solution to produce one convection form supersaturated state and precipitated crystal growth. It can be used in the preparation of nano materials, synthesis of compounds, crystal growth and so on. It can also be used in small dosage synthesis reaction. It is very common small reactor in Colleges and universities.
       
      二、水热合成反应釜使用注意事项:
      Two. the use of hydrothermal synthesis reactor should pay attention to:
       
        1.运用前:四氟内杯需用酸液(因实验请求)浸泡一段时间,可将四氟内杯外表的附着物清洗洁净;检查。
       
        1. Before use: the inner cup of PTFE needs to be soaked for a period of time with the acid solution (because of the experimental request), and the attachment of the inner surface of the inner cup can be cleaned and checked
       
        2.运用中:将溶剂和样品参加四氟内杯中,并保证加料系数小于80%。盖好压紧(即便压紧,四氟盖子和四氟杯体接口处仍有约1毫米的起密封作用的缝隙),再把四氟内杯放到不锈钢钢套中(钢套里面的钢垫是小面朝下),两片钢垫配合盖好,拧紧釜盖,普通不用用钢棒助力拧紧,普通男同志手拧力气曾经足够;将装好反应物并拧紧的水热釜放到烘箱中加热,当温度到达100℃时,坚持一小时,再升温到所需温度,坚持两小时。加热温度最高不能超越220℃;
        备注:依据不同的样品的技术指标,肯定不同的加热温度及加热方式。
       
        2. Application: take solvent and sample into PTFE inner cup, and ensure feeding coefficient less than 80%. Cover pressing (even pressing the lid and the cup body, Teflon PTFE interface still has about 1 mm sealing gap), then put in the cup on a stainless steel PTFE sleeve (steel sleeve inside steel pad is small, down) two steel pad with the cover and tighten the kettle cover, ordinary do not use steel rod power tightening, ordinary gay hand twisting strength was enough; hydrothermal reaction kettle will be installed and tighten in the oven heating, when the temperature reaches 100 DEG C, adhere to one hour, then heat up to the required temperature, adhere to two hours. The maximum heating temperature should not exceed 220 degrees centigrade;
        Note: according to the technical indicators of different samples, different heating temperature and heating mode are affirmed.
       
        3.运用后:反应完毕后,不可立刻把水热釜拧开,要确认釜内温度低于反赢物系种溶剂沸点后,先用钢棒把釜盖旋扭松开,然后将釜盖翻开。冷却后外罐能够很轻松翻开,假如打不开,用钢棒助力翻开。实验完毕要及时将其清洗洁净,以免锈蚀水热合成反应釜。釜体、釜盖线密封处要格外留意清洗洁净,并严防将其碰伤损坏。
       
        3. After use: after the reaction is finished, the kettle can not be unscrewed immediately. To confirm that the temperature in the kettle is lower than the boiling point of the solvent, the steel rod is used to unscrew the lid of the kettle, and then the kettle lid is opened. After cooling, the outer tank can be easily opened, if not open, with steel rods help turn over. The experiment should be cleaned in time, so as to avoid the corrosion of hydrothermal synthesis reactor. Kettle body, kettle cover line sealing place should pay special attention to cleaning and cleaning, and to prevent damage.
