Heat preservation liner of water heater

Abstract

The invention relates to a heat preservation liner of a water heater. The heat preservation liner comprises an inner anticorrosion layer and an outer heat preservation layer which are tightly connected, the inner anticorrosion layer is an enameled layer, an anti-oxidation magnesium layer is coated with the inner wall of the enameled layer, the outer heat preservation layer is a plastic layer which can be one of a PP plastic layer, a PE plastic layer and a PC plastic layer, and a heat absorptive coating layer is coated with the inner wall of the outer heat preservation layer. The heat preservation liner has the advantages of corrosion resistance, good heat preservation effect and high safety.

Description

technical field [0001] The invention relates to the technical field of thermal insulation liner, in particular to a thermal insulation liner of a water heater. Background technique [0002] The water heater liner is an important part of the water heater. The thermal insulation performance of the water heater liner is an important performance index of the water heater. At present, the most used plastic liner and stainless steel liner in the market, the plastic liner material has poor heat resistance and is easy to deform. Containing modified materials, it is easy to produce water pollution and endanger human health; the manufacturing process of stainless steel liner is complicated, the acid and alkali resistance is poor, easy to scale, the welding seam is long, the welding part is easy to oxidize and corrode when heated, and leaks; although there are also The enamel liner is brittle and not easy to transport. How to cushion the enamel liner to keep warm and easy to transport ...

[0002] The water heater liner is an important part of the water heater. The thermal insulation performance of the water heater liner is an important performance index of the water heater. At present, the most used plastic liner and stainless steel liner in the market, the plastic liner material has poor heat resistance and is easy to deform. Containing modified materials, it is easy to produce water pollution and endanger human health; the manufacturing process of stainless steel liner is complicated, poor acid and alkali resistance, easy to scale, long welding seam, easy to oxidize and corrode when heated, and leak; although there are also The enamel liner is brittle and not easy to transport. How to cushion the shock to make the enamel liner both heat-resistant and easy to transport remains to be studied
