I-acid soldering flux yetyhefu

I-acid soldering flux yikhemikhali esetyenziselwa ukucoca nokukhusela indawo apho iziqwenga zentsimbi zidityaniswe khona. Ityhefu yetyhefu yenzeka xa umntu eginya le nto.

Eli nqaku lelolwazi kuphela. SUKUYISETYENZISE ukunyanga okanye ukulawula ukubonakaliswa kwetyhefu uqobo. Ukuba wena okanye umntu onaye une-exposure, fowunela inombolo yakho yongxamiseko yendawo (enje nge-911), okanye iziko lakho lendawo yetyhefu linokufikelelwa ngokuthe ngqo ngokutsalela umnxeba kwinombolo yasimahla yoNcedo lweTyhefu (1-800-222-1222) naphi na eUnited States.

Izinto eziyingozi kwi-soldering fluxes zibizwa ngokuba ziihydrocarbon. Ziquka:

• Ammonium chloride
• Rosin
• Ihydrochloric acid
• Zinc chloride

I-Soldering flux iqulethe ezi zinto zilapha ngasentla.

Ezinye iimveliso zinokuqulatha ukubhobhoza.

Apha ngezantsi ziimpawu zetyhefu ebhobokayo kwiindawo ezahlukeneyo zomzimba.

AMEHLO, IINDlebe, iimpumlo, nomqala

• Ukuphulukana nombono
• Intlungu ebuhlungu emqaleni
• Intlungu ebukhali okanye ukutshisa empumlweni, amehlo, iindlebe, imilebe, okanye ulwimi

IINTSHINTSHO NEBHOLA

• Ukuncipha kwemveliso yomchamo
• Ukungaphumeleli kwezintso

ISisu kunye namathumbu

• Igazi esitulweni
• Ukutshiswa kombhobho wokutya (umqala)
• Iintlungu ezinzima zesisu
• Isicaphucaphu nokugabha
• Ukuphalaza igazi

IINTLIZIYO ZENTLIZIYO NEGAZI

• Ukuwa
• Ukubetha kwentliziyo ngendlela engaqhelekanga
• Uxinzelelo lwegazi olusezantsi olukhula ngokukhawuleza (ukothuka)

AMANDLA NEENDLELA

• Ukuphefumla ubunzima (ngokuphefumla kwimichiza)
• Ukudumba komqala (kunokubangela nobunzima bokuphefumla)

ULusu

• Tshisa
• Imingxunya kulusu okanye kwizicwili phantsi kolusu
• Ukucaphuka

Fumana uncedo lwezonyango kwangoko. MUSA ukumenza umntu aphose ngaphandle kokuba ulawula ityhefu okanye umniki-nkonzo akuyalela. Ukuba ukubhobhoza kulusu okanye emehlweni, coca amanzi amaninzi ubuncinci imizuzu eyi-15.

Ukuba umntu uginye ukubhoboka, mnike amanzi okanye ubisi kwangoko, ukuba umboneleli ukuxelela ukuba wenze njalo. SUKUNIKA nantoni na ukuba isele xa umntu eneempawu ezenza ukuba kube nzima ukuginya. Oku kubandakanya ukugabha, ukuxhuzula, okanye inqanaba lokuncipha lokuqaphela. Ukuba umntu uphefumle umphunga wokuhamba, mthumele kumoya omtsha kwangoko.

Ngaba olu lwazi lukulungele:

• Ubudala bomntu, ubunzima, kunye nemeko
• Igama lemveliso (kunye nezithako, ukuba ziyaziwa)
• Ixesha laliginyiwe
• Isixa siginyiwe

Iziko lakho lokulawula ityhefu lingafikelelwa ngokuthe ngqo ngokutsalela umnxeba wenombolo yasimahla yasimahla kuTyhefu (1-800-222-1222) naphi na e-United States. Inombolo yomnxeba kazwelonke iya kukuvumela ukuba uthethe neengcali kwiityhefu. Baza kukunika eminye imiyalelo.

Le yinkonzo yasimahla neyimfihlo. Onke amaziko olawulo lwetyhefu aseMelika asebenzisa le nombolo yesizwe. Kuya kufuneka ubize ukuba unemibuzo malunga netyhefu okanye ukuthintela ityhefu. AKUFUNI ukuba ibe yingxakeko. Ungatsalela umnxeba nangasiphi na isizathu, iiyure ezingama-24 ngosuku, iintsuku ezisi-7 ngeveki.

Thatha isikhongozeli uhambe naso esibhedlele, ukuba kunokwenzeka.

Umboneleli uya kulinganisa kwaye abeke esweni iimpawu ezibalulekileyo zomntu, kubandakanya iqondo lobushushu, ukubetha kwentliziyo, inqanaba lokuphefumla, kunye noxinzelelo lwegazi.

Uvavanyo olunokwenziwa lunokubandakanya:

• I-Bronchoscopy-ikhamera ezantsi komqala ukujonga ukutsha kwi-airways nasemiphungeni
• I-x-ray yesifuba
• I-ECG (i-electrocardiogram okanye ukulandelwa kwentliziyo)
• Ikhamera ye-Endoscopy ezantsi emqaleni ukujonga ukutsha kwi-esophagus nakwisisu

Unyango lunokubandakanya:

• Ulwelo ngomthambo (ngo-IV)
• Iyeza lokunyanga iimpawu
• Tube ngomlomo ungene esiswini ukuze uhlambe isisu (ukuhlamba isisu)
• Ukuhlamba ulusu (ukunkcenkceshela), mhlawumbi rhoqo kwiiyure ezimbalwa kwiintsuku ezininzi
• Utyando lokususa isikhumba esitshisiweyo
• Ukuxhasa ukuphefumla, kubandakanya ityhubhu ngomlomo ukuya emiphungeni kwaye uqhagamshele kumatshini wokuphefumla (i-ventilator)

Ukusebenza kakuhle komntu kuxhomekeke ekubeni ityhefu kangakanani na kwaye lonyango lufumaneka ngokukhawuleza kangakanani na. Uncedo olukhawulezileyo lwezonyango lunikwa, ngcono ithuba lokuchacha. Umonakalo unokuqhubeka ukwenzeka kangangeeveki ezimbalwa emva kokuginya ukujikeleza kwe-soldering.

Ukuginya ezo tyhefu kunokuba neziphumo ezibi kumalungu amaninzi omzimba. Ukutshiswa kwindlela yomoya okanye kwithumbu kunokukhokelela kwi-necrosis yethishu, okukhokelela kusulelo, ukothuka kunye nokufa, kwaneenyanga ezininzi emva kokuba into iginyiwe okokuqala. Iimpawu zinokubakho kwezi zihlunu, zikhokelela kubunzima bexesha elide ngokuphefumla, ukugwinya kunye nokwetyisa.
