An aerosol-generating system including an aerosol-generating article and the aerosol-generating device is also provided.

A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

A ceramic composition for coating metallic surfaces, a method and a resulting ceramic layer, which layer refers to a ceramic composition which, after deposition, is subjected to a thermal treatment to generate a ceramic layer. The resulting ceramic layer displays, among other characteristics, appropriate adhesion to the metallic surface and remains stable at temperatures between 750 C. and 950 C.

The present disclosure provides systems and methods for in-line thermal flattening and enameling of steel sheets. The systems and methods include an in-line thermal flattening of a feed stock steel sheet and a subsequent enamel coating of the steel sheet. The resulting enamel coated steel sheet has improved flatness compared with other coated steel sheets that are enamel coated but do not undergo the in-line thermal flattening. The systems and methods allow the use of less expensive source materials without sacrificing quality in the finished enameled product.

A method of constructing a water heater includes the steps of providing a tank having a metal interior tank wall and a heat exchanger positioned within the tank, coating the interior tank wall and the heat exchanger with a first layer comprising glass enamel, and coating a portion of the first layer with a second layer comprising an organic polymer to protect the portion of the first layer from exposure to water in the tank.

A double glass coated steel tank for a high temperature water heater and its method of fabrication is described. The tank is constructed of steel welded parts and fittings are secured to the tank without the presence of sharp edges being formed on the inner surface of the tank not to form any weakness in the composite glass coating to be applied. A first water resistant base coat of cobalt glass enriched with ZIRCON (trademark) is applied to the inner surface and the tank is heat fired at a high temperature in the order of about 1600 degrees F. A second high temperature water resistant glass coat, having a fine gas bubble size not exceeding 10 microns, is applied over the first coat and the tank is heat fired a second time. The composite glass coating thus formed is highly water and corrosion resistant in a water environment of up to at least 190 degrees F.
