Problems solved by technology
It is made by coating and firing a layer of inorganic ceramic glaze on ordinary steel plates. The cost is high, the processing technology is high, and air bubbles or pinholes are easy to occur during the production process.
In addition, enamel will gradually dissolve and peel off in hot water, which is technically called "boiling water weight loss". This kind of gallbladder is the most hygienic when it is in good condition, but many of them have quality problems, or the enamel falls off for a long time, which will pollute the water quality, rust, leak, and failure rate. very high
All of the above factors will cause the ordinary steel plate under the enamel coating to be exposed, resulting in corrosion and water leakage.

Embodiment Construction
[0013] A carbon fiber composite material pressurized water heater liner is formed by butt jointing of two U-shaped grooves injection-molded by carbon fiber composite material. In order to simplify the manufacturing process, two U-shaped grooves are arranged symmetrically on the left and right. An asymmetric structure can also be adopted as required.
[0014] (1) Carbon fiber composite material is used, and its formula is: polypropylene resin accounts for 50-80%; the reinforcement is carbon fiber, the length is 0.5-5mm, accounting for 10-30%; antioxidant 1010 accounts for 0.1-2%; ultraviolet absorber UV-327 accounts for 0.1-1%; mica powder 500 mesh accounts for 10-30%, wherein the percentage is by weight;
[0015] (2) Preparation method: put each raw material into the high mixer according to the percentage of the above formula, and fully stir it below 100°C to make the various raw materials mix evenly, and keep the raw materials dry with a moisture content of less than 0.5%, a...

Abstract
The invention relates to a bearing-type water heater inner container made of a carbon fiber composite material, which is prepared from the following materials in percentages by weight: 50-80 percents of polypropylene resin, 10-30 percents of carbon fiber as an enhancer, 0.1-2 percents of antioxidant, 0.1-1 percent of ultraviolet ray absorbent and 10-30 percents of mica powder. A preparation method comprises the following steps of: palletizing, injection molding and forming by an injection molding machine to produce two U-shaped grooves and then connecting the two U-shaped grooves to obtain a complete bearing-type water heater inner container made of the carbon fiber composite material. The bearing-type water heater inner container has the advantages of biological environmental protection,creep resistance, high temperature resistance, favorable size stability, excellent antistatic and erosiveness resistance and longer service life.
Description
technical field [0001] The invention relates to a water tank of a water heater, in particular to a carbon fiber composite material pressure-bearing water heater liner and a preparation method thereof. Background technique [0002] At present, there are mainly two kinds of materials for the inner tank of pressure-bearing water heaters on the market, stainless steel inner tank and enamel inner tank. [0003] 1. Stainless steel pressure liner. Its manufacturing process is relatively complicated: shearing plate-punching-drum-welding seam-welding various workpieces-insulation layer foaming, but its corrosion resistance, poor acid and alkali resistance, easy scaling, welding parts are easy to oxidize and rust when exposed to high temperatures, Finally, the water tank is leaked until the whole water heater is scrapped. Stainless steel material, its pressure resistance is small, easy to leak, poor heat preservation, especially in areas with poor water quality, the inner tank is se...
