Description
Technical field
The present invention relates to a kind of electric hot-water bag electrode and manufacturing approach thereof.
Background technology
Electric hot-water bag for many years in popular use on the market, its material benefit is convenient to be the good merchantable brand of heating in winter really.The copper that present electrode type electric hot-water bag generally uses, iron, stainless steel metal electrode exist salting liquid generation oxidation reaction and the electrolytic corrosion that electrode itself is easy and generate heat, and electrode life is extremely short; Also occur variable color, feculence, electrode surface in appearance when the solution chemistry composition changes in the electrode generation oxidation back pkt. and gather bad physical phenomenons such as oxide easily, make heating power continue the defective of many use common metal electrodes existence such as gradually changing.
Summary of the invention:
In order to overcome the deficiency of prior art, the present invention provides that a kind of long service life, heating power are relatively stable, the electric hot-water bag electrode and the manufacturing approach thereof of safety, environmental protection.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of electric hot-water bag electrode, it is to be processed by the raw material of following mass percent: graphite is 60%～65%, pitch is 30～35%, roasting grinding powder is 0～6%.
The manufacturing approach of said electric hot-water bag electrode, its step is following:
A: weighing above-mentioned material;
B: mix through preformer and to pinch to evenly;
C: with 250 tons of forcing press extrusion modlings;
D: with baking furnace roasting 20～30 hours, sintering temperature was 1800 ℃～2600 ℃;
E: roasting is after the grinder grinding-shaping.
The invention has the beneficial effects as follows: the electric hot-water bag electrode that adopts this technology to make; It can improve more than 10 times than the electrode life that ordinary metallic materials such as copper, iron, stainless steel are processed; Promptly brought up to more than 7200 hours in about 720 hours from life cycle in the past; The same size electrode uses equal specification electric hot-water bag; Using under the power situation identical with function, the salt of heating liquid (being the semiconductor that generates heat usually with sodium chloride) concentration is compared the common metal electrode and can be descended 10%, promptly from the past 0.055% drop to 0.05%; This material can not change making chemistry and physics that situation that the electric hot-water bag positive and negative electrode uses issues hot-salt solution for a long time, with the salting liquid that generates heat any chemical reaction does not take place yet; Be set at identical initial heating power with 20 ℃ of normal temperature, under the prerequisite of 10 ℃ of common environments for use, make comparisons, heating power can dwindle 25% with the variation that heating salting liquid variations in temperature is compared same size common metal electrode.The 810W that 300W in the time of can be from 10 ℃ rises to 75 ℃ 920W when using when being improved to 10 ℃ behind this material 350W to 75 ℃.The present invention can effectively improve easy oxide etch of electrode and the electrode surface area poly oxide that traditional electrical hot-water bottle common metal electrode in use exists; Technical barriers such as power stability is poor, it is quick-fried to be prone to boil, the life-span is short have also been eliminated solution variable color in use, spoiled, feculence simultaneously well and have been caused the bad phenomenon of people's Psychological Panic.
