How to maintain the enamel reactor?

If it is worn, you can use a simple repair agent, there are many that can be found on the market at present, the Soray series is good, you can search for it, if it is other problems, you can also consult them.

Of course, it can be fiercely good, but it can be repaired with polymer lead composite materials.

At present, the enamel reactor is damaged and many are directly returned to the factory to re-enamel, but the cost of this method is higher, and the cavity is time-consuming and laborious, and there is the use of enamel anti-round blind kettle repair, and the more enamel reactor repair agents used on the market are YK-8402 and YK-8406 enamel repair agents of Yimu Kun Rubber Industry.

How to make up for the electric welding of the enamel return surface of the reactor 01 Selection of materials: according to the size, medium and temperature of the corrosion part of the enamel reactor, select the appropriate polymer composite materials 02 Detection of damaged parts: first check whether there is a perforation, if necessary, repair welding for the hole part.

Manual arc welding should be used during repair welding, and the electrode material should be the same or similar to the base material. Thin welding rods, small currents, and intermittent welding are used to prevent porcelain explosion again. After the repair welding is completed, it is naturally cooled to room temperature and allowed to stand for more than 12 hours to fully release the welding stress.

03 Surface treatment: Use a grinder, electric grinding and other tools to polish the deporcelain part to the original color of the metal, and brush the surface of the undecorated surface within the range of 50 100mm, and ensure that a rough surface is obtained when grinding. After grinding, the surface is cleaned with absolute ethanol (analytically pure) to ensure that there are no residues.

Check whether there are dark lines on the surface of the surrounding enamel, and if there are dark lines, continue to polish and re-clean with absolute ethanol for inspection. 04 Blending materials: Mix resin and curing agent in strict accordance with the volume ratio specified in the description of polymer composite materials 2211F, and fully mix until the color is uniform and consistent.

After mixing evenly, it should be spread out thinly to dissipate heat and used in time. In order to avoid waste, materials should be prepared according to the amount used and used up within the specified period of application. 05 Coating Material:

Apply the blended 2211F repair material to the treated metal surface, the first layer should be thin and vigorously applied to ensure that the material penetrates into every crevice of the substrate; Then apply layer by layer to increase the thickness of the material and reduce the presence of air bubbles in the material as much as possible. 2211F material can be cured naturally or by heating, and after curing to a hard surface, the enamel layer on the surface of the material is removed with 60 mesh sandpaper to completely remove the residual material debris and dust on the surface. Then mix the series of anticorrosive materials in proportion (EE-121K, EE-101 or 498 high-cross-linked polymer double carbon composites are selected according to the medium conditions), apply the blended anticorrosive materials to the enamel surface around the 2211F material and the limb chayou, and ensure that the material does not leave any pores, and ensure that the material does not exceed the range of the enamel surface of the hairing.

The number of heavy coatings is subject to the required thickness. 06 Inspection: After each layer of material is coated, carefully inspect the material before it is cured, and repair the parts that are not coated tightly and the thickness of the material is thin.

If necessary, an ultraviolet lamp can be used for inspection. After the last layer of material has been applied and cured, the coating thickness is checked with a coating thickness gauge and repeated if it falls below the specified value. The final coating is cured 24 hours after an EDM test.

07Curing: Sufficient curing time according to the material technical data sheet. Heating the material shortens the curing time, and heating the curing can also improve the properties of the material itself, including resistance to chemical corrosion, high temperatures, and other physical properties of its own.

Summary. Enamel reactor, if there is an air socket phenomenon, it will lead to a decrease in its corrosion resistance, resulting in the phenomenon of decelonization and porcelain explosion, so it is an important job to take measures to prevent the appearance of air sockets, the methods are as follows:

1. In the blades of the enamel reactor, gas is injected.

2. At or close to the boiling point, stir the solvent in the enamel reaction kettle and stir it evenly.

3. Stir at a lower level of liquid level, and the enamel reactor blades are not completely covered.

In short, in order to prevent the enamel reactor from having an air socket, during operation, you can stir at a low level, reduce the stirring rate, and pay attention to cleaning the equipment regularly and taking safety measures, so as to prevent it from appearing in the air socket.

Kiss Follow the steps.

Enamel reactor is a relatively common reaction kettle, which has the characteristics of acid and alkali resistance, corrosion resistance, wear resistance, easy cleaning, etc., and is usually used in some special chemical reactions or production processes, such as:

1.Food processing industry: the production of acidic or alkaline food and beverages, such as juice, beverages, yogurt, sauerkraut, etc., the enamel reactor can withstand the corrosion of these acid and alkali substances, and at the same time easy to clean, no peculiar smell and colorless, to ensure the quality of food hygiene.

2.Pharmaceutical industry: the production of pharmaceutical raw materials, intermediates and finished drugs, the enamel reactor has the ability to resist acid and alkaline substances, and at the same time has the characteristics of sterility, non-toxicity and no peculiar smell, which can ensure the quality and purity of drugs.

3.Chemical industry: in the production process of sodium hydroxide, sodium chloride, sulfuric acid and other chemical products, the reactor is usually eroded by strong acid beam alkali, and the enamel reactor can withstand high concentration of strong acid and alkali erosion to prolong the service life of the equipment.

4.Electroplating industry: The electroplating solution reactor is usually responsible for the reaction and precipitation of the electrolyte, and the enamel reactor can withstand the strong acid and alkali corrosion and high temperature and high pressure violent reaction of the rubber and Hengsen in the plating solution.

It should be noted that due to the limited adhesion and wear resistance of the porcelain layer, the enamel reactor also needs to pay attention to maintenance and maintenance during daily use to ensure the normal and stable operation of the equipment.

Hello, I'm glad to answer for you, first, the heating rate is too high The process of heating the electric heating reactor takes a certain amount of time, so it can not be rushed, but many users have made this mistake, so as to adjust the heating rate too high, making it difficult to control the temperature stably or the equipment, and there will inevitably be a problem of slow heating speed, and this kind of operation error must be avoided. Second, the problem of the insulation layer If the heating rate is normal, the reason for the slow heating speed of the electric heating reactor may also be related to the insulation layer, but it can be divided into two directions to discuss, the first situation is that the insulation layer is damaged, resulting in difficulty in maintaining a stable high temperature, and the second is that the insulation layer is wet, resulting in a decrease in the insulation effect. 3. The heating material volume is large As we all know, the heating time of the substance is closely related to its own volume, if there is no problem in the insulation layer, heating rate, etc., the reason for the slow heating speed of the electric heating reactor may be that the user is heating the material with a large volume, which will inevitably lead to the heating time will be extended.

In general, the above three situations are the main reasons for the slow heating speed of the electrically heated reactor, and they are usually caused by incorrect use or insufficient maintenance, so the user must maintain the product accordingly after purchasing the product.

Summary. Enamel reactor, split and closed two structures, open for the body cover separation, the middle is connected with a mat and clip, generally the volume is below 5000L; The closed type is integrated with the body cover, and the general volume is more than 5000L. These two structures have their own advantages, the open type is more convenient to disassemble, if there is a problem with the nozzle on the tank lid, it is easy to remove it for separate repair, and the closed type has better sealing performance.

Generally speaking, there are two types of open structures: flat welded butt flange connection and flat cover type.

At present, it is widely used in various chemical, pharmaceutical, printing and dyeing, winemaking, health care products and other production fields. Since the linear expansion coefficient and elongation of the enamel are less than those of the steel plate, the deformation of the glass-lined glass after cooling is less than that of the steel plate, so that the enamel will be constrained by the steel plate and produce compressive stress. When the enamel storage tank is made, the enamel layer has a pre-compression stress, while the steel plate has a pre-tensile stress.

Because the prestress is related to the linear expansion coefficient and elongation, and the linear expansion coefficient and elongation are closely related to the temperature, the working temperature of the enamel storage tank has a great influence on its use. If the stress generated by the enamel exceeds its use stress due to large temperature changes, the enamel will be destroyed. The purpose of enamel storage tanks is mainly to hold corrosive chemicals, such as various strong acids.

The enamel reactor has a wide range of applications, and its specifications and costs are not the same, and the manufacturer should choose the products of the enterprise with the production license of glass-lined equipment. And to confirm the variety and specifications of the purchased products, whether the manufacturer is qualified to produce (each licensed enterprise has the production license of the enterprise to allow the production of the product varieties and specifications).
