Indlela yokukhetha ukuhamba kwe-soldering

Into ebaluleke kakhulu ekulungiseni nasiphi na isisombululo isilungisa. I-Solder, i-fluxes, i-solder nonte - konke oku kufuneka kuthathelwe ingqalelo xa wenza umsebenzi wokulungisa. Ukuba kunye ne-solder yonke ayicacile - ngokuqhelekileyo oku kusebenzisa abathengisi be-tin ehamba phambili ngamaphupha ahlukeneyo (kuxhomekeke ekubunjweni kwe-alloy), ngoko kuthekani malunga nokuhamba? Yintoni na?

Injongo ephambili ye-flux isuswa kummandla we-oxides, kunye nokunciphisa ukuxhatshazwa komhlaba ukuze kuphuculwe ukusasazeka kwe-solder. Ukongezelela, ukuhamba kwe-soldering kunceda ukukhusela umxube kwimiphumo yendalo yangaphandle.

Ziziphi iifomati?

Ngokwempembelelo yayo kwizakhiwo zetsimbi, i-fluxes yilezi zilandelayo.

• I-Active (nayo ibizwa ngokuba yi-asidi). Ziqukethe i-hydrochloric acid, i-fluoride kunye ne-chloride. I-flux esebenzayo yokwenza i-soldering ngamandla ikhupha ifilimu ye-oxide eyenziwe phezu kweso sinyithi, ngaloo ndlela iqinisekisa ukuxhaswa kwamandla ophezulu ozayo. Kufuneka kukhunjulwe ukuba umbane osebenzayo awufanelekanga ukulungiswa kwezixhobo zombane, ekubeni i-residu yayo idibanisa indawo ye-soldering ngokuhamba kwesikhathi.
• I-Acid-free . Ezi ziquka i-rosin, kunye ne-rosin-based based flux nge-addition of turpentine, utywala okanye i-glycerin. I-acid-free free flow for soldering ihlambulule kuphela isitrato kwi-oxides, kodwa iyakhusela kwakhona kwi-oxidation eqhubekayo. Ukongezelela, ukusetyenziswa kwe-rosin akubangeli ubumbano bomhlaba. Ngokuqhelekileyo isetyenziselwa ukuxubha ithusi, ithusi kunye neethusi.
• Yenziwe . Ilungiselelwe ukusuka kwi-rosin, eyongezwa kwixabiso elincane le-phosphoric okanye i-hydrochloric acid aniline, i- salicylic acid kunye ne-hydrochloric acid diethylamine. Ukuququzelela ukukhupha i-soldering ingasetyenziselwa iintlobo ezininzi zeesinyithi kunye nama-alloys (isinyithi, ubhedu, i-nickel, ithusi, i-nichrome, isilivere, isinyithi). Ingasetyenziselwa ukuxutywa kweengxube ze-alloys zethusi ngaphandle kokuqhawulwa kwazo kwangaphambili.
• Ukuxhamla . Ezi ziqulatho zenziwa kwi- phosphoric acid kunye nokudibaniswa kwee-solvents ezahlukahlukeneyo kunye nama-organic compounds. Ukongezelela, ezinye zezi zihlunu zibandakanya i-acid acid. I-flux ye-anti-corrosion isetyenziselwa ukuxubha ithusi kunye ne-alloys yayo, kunye nesilivere, i-platinum kunye ne-constantan.
• Khusela . Ezi ziquka ioli yomnquma, i-wax, i-petroleum jelly, ishukela elenziwe ngompu. Iimfucuza zokukhusela azikho umphumo weekhemikhali kwintsimbi, kwaye zikhusela nomhlaba ococekileyo kwi-oxidation.

Ukongezelela, iimveliso zenziwe nge-iron cast, i-carbon diels, kunye nobhedu kunye ne-alloys yayo, i-drill (i-sodium tetraborate) isetyenziswe i-powder e-white crystalline ene-melting point 741 ° C.

Kwakhona, i-borax (ngokuchanekileyo, umxube wayo ne-boric acid kwisilinganiso se-1: 1) isetyenziselwa ukukhonkxa isinyithi esingenasici kunye nama-alloys enzima .

Njengoko ukuveliswa kwemveliso yobhedu kusetyenziswa umxube onamalungu alinganayo weetyuli zetyuwa kunye ne-calcium chloride.

Ukuxutywa kweemveliso ze-aluminium kudinga ukukhuphaza okunomlinganiselo ophantsi. Ngokuqhelekileyo, ukuhamba kwe- aluminium e-solder iqukethe i-30 ukuya ku-50% ye-potassium chloride.

I-Flux yokwenza i-soldering inokuveliswa ngendlela ye powder, liquid or paste. Ukongezelela, kukho i-solder ekhethekileyo, apho iinqununu ze-solder sele ziqulethe kunye ne-flux.

Yintoni ebalulekileyo ukwazi xa wenza i-soldering

Xa ukhetha ukuhluthwa kwe-soldering, kungekhona kuphela izinto eziphathekayo kwiindawo ekufuneka zithengiswe ngazo, kodwa kwakhona oko kusetshenziswe i-solder, kuthathwa ingqalelo. Ingqungquthela yokuqhaqhaqhafaza akufanele idlule i-melting point of solder.

Kungakhathaliseki ukuba luhlobo luni lokusetyenziswa, kuyimfuneko ukusula indawo yokuxutywa emva komsebenzi ngendwangu enciphise i-acetone okanye kwi-alcohol-certified. Emva koko hlambulula le ndawo ngebhasi okanye ukuxubha ehambileyo nayiphi na isisombululo ukuze ususe ama-resix. Oku kuyinyani ngokukodwa kwi-flux esebenzayo, kuba iimveliso zokuqhekeza kwazo azigcini nje kuphela ukungcolisa indawo yokuxutywa, kodwa kwakhona yindawo yokubola.
