Bangane abashiselayo abathandekayo, imisebenzi yokushisela kagesi enisebenza kuyo ingase ihlanganise izingozi zentuthu yensimbi, izingozi zegesi eziyingozi, nobungozi bemisebe ye-arc light phakathi nomsebenzi wakho. Kufanele ngikwazise ngezinto eziyingozi kanye nezinyathelo zokuzivikela!
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)
1. Izingozi zomsebenzi zokushisela ugesi
(1) Izingozi zentuthu yensimbi:
Ukwakheka kwentuthu yokushisela kuyahlukahluka kuye ngohlobo lwenduku yokushisela esetshenzisiwe. Ngesikhathi sokushisela, ukukhishwa kwe-arc kukhiqiza izinga lokushisa eliphezulu lika-4000 kuya ku-6000 ° C. Ngenkathi incibilikisa induku yokushisela kanye ne-weldment, kukhiqizwa intuthu enkulu, ikakhulukazi eyakhiwe nge-iron oxide, i-manganese oxide, i-silica, i-silicate, njll. Izinhlayiya zentuthu zingena endaweni yokusebenza, kulula ukuhogela. emaphashini.
Ukuhogela umoya isikhathi eside kungabangela izilonda zemicu emaphashini, okubizwa ngokuthi i-welder's pneumoconiosis, futhi kuvame ukuhambisana nezinkinga ezifana nobuthi be-manganese, i-fluorosis kanye ne-metal fume fever.
Iziguli ikakhulukazi ziba nezimpawu zokuphefumula ezinjengokuqina kwesifuba, ubuhlungu besifuba, ukuphelelwa umoya, nokukhwehlela, okuhambisana nobuhlungu bekhanda, ubuthakathaka obujwayelekile nezinye izimpawu. Umsebenzi wamaphaphu we-qi nawo wonakaliswa ngezinga elithile.
(2) Izingozi zamagesi ayingozi:
Ngaphansi kwesenzo sokushisa okuphezulu kanye nemisebe eqinile ye-ultraviolet ekhiqizwe i-arc welding, inani elikhulu lamagesi ayingozi, njenge-nitrogen oxides, i-carbon monoxide, i-ozone, njll, lizokhiqizwa endaweni ye-arc.
Lapho inani elikhulu le-hemoglobin lihlangana ne-carbon monoxide, umoya-mpilo ulahlekelwa ithuba lokuhlangana ne-hemoglobin, okubangela izithiyo emandleni omzimba okuthutha nokusebenzisa umoya-mpilo, okubangela ukufa kwezicubu zomuntu ngenxa yokuntuleka komoya-mpilo.
(3) Izingozi ze-arc radiation:
Ukukhanya kwe-arc okukhiqizwa ngokushisela ikakhulukazi kuhlanganisa imisebe ye-infrared, ukukhanya okubonakalayo nemisebe ye-ultraviolet. Phakathi kwabo, imisebe ye-ultraviolet ilimaza umzimba womuntu ikakhulukazi ngemiphumela ye-photochemical. Ilimaza amehlo nesikhumba esiveziwe, ibangele i-keratoconjunctivitis (photoophthalmia) kanye ne-skin biliary erythema.
Izimpawu eziyinhloko zihlanganisa ubuhlungu bamehlo, ukudabuka, ububomvu bejwabu leso kanye ne-spasm. Ngemva kokuvezwa emisebeni ye-ultraviolet, isikhumba singase sibonakale i-erythema edematous enemingcele ecacile. Ezimweni ezimbi kakhulu, ama-blister, i-exudate kanye ne-edema ingase ibonakale, kanye nomuzwa ocacile ovuthayo.
2. Imiphumela eyingozi ye-welding kagesi
1. Abantu asebenesikhathi eside benza i-welding kagesi basengozini enkulu yokuthola i-pneumoconiosis.
2. Amagesi ayingozi angase ahogele phakathi nokusebenza, asongela impilo yomuntu ngisho nokuphila.
3. Ukusebenza kwe-welding kagesi kungabangela kalula i-keratoconjunctivitis (electrophotophthalmia) kanye ne-skin biliary erythema.
3. Izinyathelo zokuphepha
(1) Thuthukisa ubuchwepheshe be-welding futhi uthuthukise izinqubo zokushisela nezinto zokwakha
Ngokuthuthukisa ubuchwepheshe bokushisela, singanciphisa ukulimala emzimbeni womuntu okubangelwa imisebenzi yokushisela. Njengoba izingozi eziningi ezibangelwa ukushisela zihlobene nokwakheka kwe-electrode coating, ukukhetha ama-electrode okushisela angenabuthi noma anobuthi obuphansi nakho kungenye yezinyathelo eziphumelelayo zokunciphisa izingozi zokushisela.
(2) Ukwenza ngcono izimo zokungena komoya endaweni yokusebenza
Izindlela zokungenisa umoya zingahlukaniswa zibe umoya omncane wemvelo kanye nokungenisa umoya ngemishini. Ukungena komoya ngomshini kuncike engcindezini ekhiqizwa abalandeli ukuze bashintshisane komoya. Inemiphumela engcono yokususa uthuli kanye ne-detoxification. Ngakho-ke, kufanele isetshenziswe lapho ushisela ezindaweni ezingaphakathi noma ezivaliwe ezinomoya omncane wemvelo. Izinyathelo zokungena komoya ngomshini.
(3) Qinisa izinyathelo zokuzivikela
Ukuqinisa ukuvikelwa komuntu siqu kungavimbela ukulimala kwamagesi anobuthi nothuli olukhiqizwa ngesikhathi sokushisela. Ama-opharetha kufanele asebenzise izibuko zokuzivikela ezifanele, izihlangu zobuso, izifihla-buso, amagilavu, izingubo zokuzivikela ezimhlophe, nezicathulo ezigqunyiwe. Akumele bagqoke izingubo ezinemikhono emifushane noma imikhono egoqiwe. Uma besebenza esitsheni esivaliwe esinezimo ezingezinhle zokungenisa umoya, kufanele bagqoke nezimpahla zokuzivikela. Isigqoko sokuzivikela esisebenza komoya.
(4) Qinisa ukuvikelwa kwabasebenzi umsebenzi wokukhangisa nokufundisa
Abasebenzi bokushisela kufanele bafundiswe ngolwazi oludingekayo lokuphepha kanye nolwazi lwezempilo ukuze bathuthukise ukuqwashisa kwabo ngokuzivikela kanye nokunciphisa izingozi emsebenzini. Ngesikhathi esifanayo, kufanele futhi siqinise ukuqapha kwezingozi zothuli ezindaweni zokusebenza zokushisela kanye nokuhlolwa ngokomzimba kwama-welders ukuze kutholwe futhi kuxazululwe izinkinga ngesikhathi.
