Description

Gas mask is used in electric welding

Technical field

The utility model relates to a kind of welding protective articles, are specifically a kind of electric welding gas masks.

Background technique

Electric welding is the very high technology of a special kind of skill gold content, arrives space flight navigation greatly, small to many works used in family Tool will use electric welding to complete, and be welded work due to working environment, and many places are all closed very much, what when electric welding generated The protection tool mask designs that toxic gas, dust etc. are all used because of electric welder are incomplete, have been drawn into the lung of people, sternly The body of welding worker is compromised again.

Electric welding melts a kind of welding behaviour that metal parts needs the place connected to realize by high arc temperature using welding rod Make, and welding wire and welding material can generate various chemical gas in the case where welding hot conditions, such as manganese, chromium, nickel, carbon monoxide, smelly Oxygen and nitrogen oxides etc., dust, high temperature, radiation, electro-welding arc and noise that electrode welding process can also generate etc., all to the danger of human body Evil is very big.In addition after a large amount of newborn manganese oxide smog of human body sucking, it may occur in which brass chill, show as dizziness, have a headache, is weary Power, nausea, uncomfortable in chest, dry throat, shortness of breath, fever etc., serious person can have chilly, shiver.After general a few hours to 1~2 day, heat is moved back, Whole body goes out profuse sweating.

(1) flue dust of Long Term Contact manganese can be caused with nervous system change based on disease.Early stage shows as nerve Asthenic syndrome and vegetative nerve functional disturbance.When being poisoned more apparent, there is extrapyramidal system damage, and can be with mental symptom. It can behave as Parkinson's syndrome and toxic psychosis when serious.There can be dizziness, have a headache, be easy tired, sleep disturbance, be strong Performance and the limbs pain, weakness of the lower extremities and sense of heaviness for forgetting equal neurasthenic syndromes, can have the plants such as hidrosis, palpitaition refreshing Performance through dysfunction.(2) cause the systemic disease based on central nervous system damage after human body sucking high concentration CO. Acute CO poisoning onset is anxious, incubation period is short.Gently, moderate intoxication is mainly shown as headache, giddy, palpitaition, Nausea and vomiting, four limbs It is out of strength, clouding of consciousness, or even stupor, but the duration of going into a coma is short, is rescued, can comparatively fast be revived, general nothing through disengaging scene Significant complications.Severe intoxication person's disturbance of consciousness degree reaches deep coma or decortical state.(3) human body sucks nitrogen oxides It can cause acute pulmonary edema, chemical pneumonia and chemical tracheobronchitis.Long Term Contact low concentration nitrogen oxides has the upper respiratory tract Mucosal irritation symptom causes pharyngo-laryngitis chronica, bronchitis and pulmonary edema.(4) human body sucking chromium trioxide can have respiratory tract Stimulation and corrosiveness, cause rhinitis, pharyngitis, bronchitis, and erosion of nasal septum, or even perforation are made when serious.(5) human body is long-term Sucking welding fume will cause lung tissue fibrous lesions, be mainly shown as the respiratory systems disease such as uncomfortable in chest, pectoralgia, shortness of breath, cough Shape, and with headache, general weakness etc., lung also has a degree of damage by airway dysfunction.

Existing electric welder's helmet is only that simple protection face prevents from scalding to staff, and eyes is protected not pierced Wound, did not take gas defence, dust-proof processing to staff, and staff works in this toxic gas for a long time, to work people The actual bodily harm of member and its big.Protection electric welding staff avoids that it is allowed to suck toxic gas and dust is that a urgent need solves The problem of.

Utility model content
