Abstract
The invention discloses a surface treatment process for a spring of a temperature fuse. The process comprises the steps of (1) deoiling, (2) primary washing, (3) acid pickling which is conducted in 26-30 g/L hydrochloric acid at the temperature of 50-55 DEG C, (4) secondary washing, (5) heating which is conducted at the temperature of 90-100 DEG C for 10-20 min, (6) hot galvanizing which is conducted in 36-42 g/L zinc chloride, 180-200 g/L ammonium chloride, 28-32 g/L boric acid, 4-6 g/L thiourea and 3-5 g/L hydrochloric acid at the temperature of 450-480 DEG C for 40-50 min, (7) cooling to the indoor temperature, and (8) passivating treatment. By means of galvanization on the surface of the spring, the spring has the advantages of being resistant to abrasion and corrosion, high in strength and stability, good in electrical conductivity and thermal conductivity, and long in service life. The galvanization process is simple, and production is convenient.
Description
Technical field
The present invention relates to temperature fuse technical field, be specifically related to the process of surface treatment of the spring that a kind of temperature fuse uses.
Background technology
Temperature fuse is also called Thermal Cutoffs, is temperature sense loop shearing device.
What in the improper running of Thermal Cutoffs energy induction apparatus electronic product, produce is overheated, thereby cut-off loop is to avoid the generation of fire.Be usually used in: hair dryer, electric iron, electric rice cooker, electric furnace, transformer, motor, water dispenser, coffee pot etc., after Thermal Cutoffs running, cannot reuse, only under fusing-off temperature, move once.
Can be divided into organic substance type Thermal Cutoffs, porcelain tube type Thermal Cutoffs, square shell mould Thermal Cutoffs.Organic substance type Thermal Cutoffs is made up of moving contact, spring, fusable links.Before Thermal Cutoffs starts, electric current flows to moving contact from left side lead-in wire, goes between to the right mobile by metal shell.Organic substance fusable links fusing in the time that external temperature reaches predetermined temperature, Compress Spring can fluff.Be that spring expands, moving contact goes between and separates with left side.Loop is opened, and between moving contact and left side lead-in wire, electric current is cut off.At present, the spring in prior art in temperature fuse also exists technique unreasonable in the time carrying out surface treatment, the deficiencies such as spring mechanical poor performance, conduction, poor thermal conductivity.
Summary of the invention
For the problems referred to above, the invention provides the process of surface treatment of the spring that a kind of temperature fuse uses, there is good anticorrosive, abrasion resistance, the advantages such as thermal conductivity, good conductivity.
In order to address the above problem, technical scheme provided by the invention is:
A process of surface treatment for the spring that temperature fuse is used, comprises the following steps:
(1) deoil;
(2) washing for the first time;
(3) pickling, hydrochloric acid: 26-30g/L, temperature: 50-55 DEG C;
(4) washing for the second time;
(5) heating, 90-100 DEG C of temperature; Duration: 10-20 minutes;
(6) hot galvanizing, zinc chloride: 36-42g/L, ammonium chloride: 180-200g/L, boric acid: 28-32g/L, thiocarbamide: 4-6g/L, hydrochloric acid: 3-5g/L, temperature: 450-480 DEG C, duration: 40-50 minutes;
(7) be cooled to room temperature;
(8) Passivation Treatment.
Preferably, step (1) adopts alkaline solution to deoil, NaOH: 120-140g/L, sodium carbonate: 30-34g/L.
Preferably, the solvent that carries out Passivation Treatment in step (8) is: sulfuric acid: 20-24g/L, chromic anhydride: 220-240g/L, hydrochloric acid: 10-12g/L.
Compared with prior art, beneficial effect of the present invention is:
The present invention by carrying out zinc-plated processing on spring surface, have resistance to wearing, anticorrosive, intensity good, good stability, has good conductivity, thermal conductivity, long service life, and zincincation is simple, production and processing is convenient.
