The method comprises the following steps: carrying out high temperature aging for 7 hours on thermometer pipe material whose contraction throat operation is completed, taking the pipe material out and carrying out natural cooling on the pipe material to 30-40 DEG C, placing the pipe material into a vacuum cabin for mercury injection, after mercury injection, dipping the pipe material into water with a constant temperature of about 42.25 DEG C, heating one end of the pipe material to enable a mercury column to heat up and overflow, fusing an open end of the pipe material and carrying out capping processing, and selecting a thermometer with overflow length of 98-103 cm and pipe material length of 110-115 cm for carrying out subsequent processing. By employing the method provided in the invention, a production flow of the thermometer is optimized, production efficiency is raised, manpower cost is reduced, mercury evaporation pollution caused by a traditional production method is avoided, and health and security of operation personnel are ensured.
Description
Technical field
The present invention relates to a kind of production method of glass clinical thermometer, relate in particular to the production method that a kind of glass clinical thermometer does not have the vacuum that rises.
Background technology
The traditional glass mercury column clinical thermometer of the most employings of present domestic clinical thermometer.Glass mercury column clinical thermometer have the meter temperature accurately and reliably, advantage such as simple to operate, cheap, but the production run of mercury column clinical thermometer but exists great Environmental security risk and health of human body hidden danger.The production run of glass mercury column clinical thermometer comprises cuts operations such as expecting, draw neck, contracting larynx, notes mercury, end socket, branch, lettering, baking look, packing, wherein annotating steps such as the vacuum that rises in the mercury operation, distillation mercury all is directly exposed in the production environment, the aerial evaporation of mercury is threatening the enterprise employee health of production line, even may cause central lesion, serious consequences such as respiratory system depletion.
Especially in the vacuum process that rises, the vacuum bubbles glass wall is extremely thin, breaks easily when getting rid of running into hydro-extractor, and by statistics, the breakage rate of vacuum bubbles is about 20%.In addition, during to the afterbody high-temperature melting of vacuum bubbles, cause glass body to break easily to infiltrate air and keep somewhere in kapillary.Although can take measures the discharge section air in follow-up processing procedure, thoroughly emptying causes problems such as yield rate is on the low side, gravity line is defective.
Because glass body temperature family planning production. art complexity is bigger to labour demand, still belongs to labour concentrated industry.
Owing to there are the problems referred to above, the threat that a kind of new production method is avoided the mercury evaporation is as far as possible being sought in the research institution of each glass clinical thermometer and production commercial city.
Summary of the invention
The invention provides a kind of glass clinical thermometer does not have the production method of the vacuum that rises, the production technology of glass clinical thermometer is especially annotated the mercury step done great technological improvement, substituted traditional vacuum that rises, detected means such as stress with overflow the again technological means on banding top of limit, prevented that effectively glass tube from bursting, solve the mercury evaporative emission problem when rising by vacuum in the traditional mode of production operation, improved yield rate and work efficiency that the family planning of glass body temperature is produced simultaneously.
The present invention has adopted following technical scheme:
At first, 440-480 ℃ of high temperature ageing and constant temperature 6-7 hour are carried out in the semi-manufacture clinical thermometer pipe material sabot that the contracting larynx is finished, and will manage material then and naturally cool to 30-40 ℃.
Pressurized capsule is vacuumized, and vacuum tightness is not less than 2 * 10
-2Pa.After meeting the requirements of vacuum tightness, pour the liquid nitrogen processing of lowering the temperature in vacuum chamber, the temperature stabilization in the vacuum chamber exists
Below 38 ℃.To manage then and expect that putting into vacuum chamber annotates mercury.
Annotate clinical thermometer pipe material behind the mercury and soak in temperature is Water Tank with Temp.-controlled about 42.25 ℃ and heat up, the water temperature permissible error of Water Tank with Temp.-controlled is at 0.02 ℃, and soak time was not less than 1 minute.The clinical thermometer pipe material end of heating heats up mercury solution and expands, and unnecessary liquid overflows extracapillary.And then the kapillary tight burning of clinical thermometer is sealed in the openend that fuses clinical thermometer pipe material through the end socket blowtorch processing of binding.
The mercury column of take temperature meter is excessive length again, and namely the interior mercury column top of kapillary is to the length of bulb, end.The length range that overflows again is certified products at the pipe material of 98-103cm, exceeds the processing of scrapping of this scope.The length of the clinical thermometer pipe material after measurement is bound and handled, length is certified products 110-115cm's, exceeds the processing of scrapping of this scope.
Certified products are managed processing such as material end socket, branch, lettering, baking look, packing, but manufacture the finished glass clinical thermometer.
Beneficial effect of the present invention mainly shows as:
1, take the production method of glass clinical thermometer provided by the invention, significantly simplified production procedure, reduced conventional production methods the vacuum that rises, detect complex steps such as stress, improved 80% through actual measurement production efficiency, reduced operative employee's human cost 30%.
2, adopt the production method of glass clinical thermometer provided by the invention, reduced and risen by vacuum and detect the step of stress, the mercury evaporative emission of having avoided the breakage of vacuum bubbles to cause has guaranteed the operating personnel's of production line health and safety.
