When an element is referred to as being "disposed on" another element, it can be directly disposed on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 2 show a crystallizer according to the present invention, which comprises an inner tube 10 and an outer tube 20. The inner pipe 10 includes a pipe body 11 and a pipe sleeve 12. The shaft 11 is provided with an outlet 110 and the socket 12 is provided with an inlet 120. The end of the pipe body 11 far away from the outlet 110 and the end of the pipe sleeve 12 far away from the inlet 120 are welded and fixed, and the welded joint of the pipe body 11 and the pipe sleeve 12 is prone to cracking and water seepage due to temperature change in the daily use process, so that the crystallizer loses the use effect. At this time, it is necessary to fill a seal coating material between the pipe shaft 11 and the jacket 12 at the joint of the inner pipe 10 to seal the pipe shaft 11 and the jacket 12. The sealing coating is formed by uniformly mixing and stirring graphite powder and insulating paint according to the mass ratio of 45-50: 100. Under the condition of 25 ℃, when the mass part ratio of the graphite powder to the insulating paint is 45-50:100, the viscosity is 3000mPa.s-5000mPa.s, and the bonding layer strength of the cured insulating paint is 2MPa-2.5 MPa. Preferably, the graphite powder and the insulating paint are mixed and stirred according to the mass ratio of 47: 100. Under the condition of 25 ℃, the strength of the adhesive layer of the insulating paint is 2.5MPa and the strength of the adhesive layer of the insulating paint is the maximum after the graphite powder and the insulating paint are mixed, stirred and cured according to the mass part of 47: 100. The insulating paint comprises base material, fire retardant, curing agent, pigment and filler, auxiliary agent and solvent. The base material is epoxy resin. The curing agent is a water-based epoxy curing agent. Graphite powder in the sealing coating is filled in cracks of the pipe body 11 and the pipe sleeve 12 to form a graphite filling layer, insulating paint is located between the pipe body 11 and the pipe sleeve 12 and is solidified and bonded with the pipe body 11 and the pipe sleeve 12 to form an insulating paint bonding layer, the cracked inner pipe 10 is repaired, and the service life of the crystallizer is prolonged.
