Description
Technical field
The present invention relates to Welding Safety guard technology field, especially relate to a kind of welding preventer.
Background technology
Welding connects also referred to as welding, Rong, be a kind of with the mode jointing metal of heating, high temperature or high pressure or other thermoplastics as the manufacturing process of plastics and technology.The object of joint is reached in welding by following three kinds of approach: heating makes it local melting formation molten bath for the workpiece of joint, just engages, can add molten fill if desired and assist after the cooled and solidified of molten bath; The solder that independent fieWtiiltiie is lower, without the need to melting workpiece itself, the capillarity by means of solder connects workpiece; Be equivalent to or be aided with high pressure, superimposed extrusion molding or vibration etc. at temperature lower than workpiece fusing point make to interpenetrate joint between two workpiece.
According to concrete welding procedure, welding can be subdivided into other special welding such as gas welding, electric resistance welding, arc welding, induction welding and laser weld.The energy source of welding has a variety of, comprises gas flame, electric arc, laser, electron beam, friction and ultrasound wave etc.Except using in the factory, welding can also be carried out in a variety of contexts, as field, under water and space.No matter wherein, welding all may bring danger to operator, so must take suitable safeguard procedures when welding.
Welding the injury that may cause to human body, to comprise burn, electric shock, inpairment of vision, suction toxic gas, ultraviolet radiation excessive etc.
The shallow dome medicated cap of the steel that safety helmet is used to protect the crown and wears or similar raw material, prevents alluvium from injuring the protective articles of head.Be made up of cap shell, hat lining, lower cheekstrap and rear hoop.Cap shell is hemispherical, firm, smooth and have certain elasticity, and the impact and the puncture kinetic energy that hit thing bear primarily of cap shell.Leave certain space between cap shell and hat lining, available buffer, dispersion instantaneous impact, thus avoid or alleviate the direct injury to head.Impact absorption performance, puncture-resistant performance, lateral rigidity, electrical insulating property, anti-flammability are the requirements of the fundamental technology performance to safety helmet.
When operation person head is subject to the impact of falling object; safety helmet shell, hat lining is utilized first impulsive force to be decomposed on the whole area of skull in moment; then utilize the elastic deformation of safety helmet each position buffer structure, most of impulsive force absorbs by the structural deterioration of plastic deformation and permission; make the impulsive force being finally applied to person head be reduced to below 4900N, thus play the effect of the head of protection operating personnel.The cap shell material of safety helmet is resisted performance to safety helmet entirety and is played an important role.
Welding mask refers to the instrument playing protection operating personnel safety in welding operation.Light harvesting, the high-tech product that is integrated of the subject such as electronics, anthroposomatology, materialogy.The LCD of high-quality and glass plating is adopted to be combined as sunshade lens; photoinduction system on eyeglass can the generation of arc light and disappearance when detecting electric welding instantaneously; rapid driving liquid crystal shading variable colors etc. are to reach filtering noxious light safely and effectively, thus the eye of protection welder, face avoid the injury of arc light radiation.
Welding mask effectively can carry out eye protection: dual optical filtering, the ultraviolet avoiding electric arc to produce and infrared ray harmful radiation, and the injury that welding high light causes eyes, stops the generation of electric ophthalmia.
Welding mask effectively can carry out face protection: the splash effectively preventing operation from occurring and harmful body etc. cause infringement to face, reduces the generation of skin burn disease.
Welding mask effectively can carry out respiratory protection: air-flow leads, and effectively reduces the harmful gas of welding release and dust etc. to damaging in body, the generation of pre-Anti-pneumoconiosis occupation disease.
When electric welding, need to use welding mask to protect oneself, existing welding mask is commercially generally hand-held or face shield fixes welding mask with things such as fixing bands; In welding process, sometimes need both hands, so just need welding mask to be placed on one side, carry out welding or other people assist effectively to weld.
A kind of welding mask with fixing band is also had to need welding mask band when in use on head, all need to carry welding mask in whole welding process, like this can be very uncomfortable, security protection is effective, but always by welding mask with on head, can very uncomfortable, the problems such as poor air permeability, for with hand-held welding mask, hand shield can in welded gaps, easily by welding mask from removing above, increase breathability, but hand shield needs to occupy a hands, and this is again the shortcoming of hand shield.
