Aluminium sesipholisanjini indlela solder: isinyathelo ngesinyathelo imiyalelo kanye nezincomo

izimoto eziningi zanamuhla anemisila aluminium radiators indlu. Lokhu metal has a isisindo ongaphakeme, okuhle anti-ukugqwala izakhiwo, futhi ine omuhle kakhulu conductivity ezishisayo. Ngaphezu kwalokho, kuyinto kakhulu ezishibhile yethusi zethusi radiators zazo ezazenziwe ngaphambili.

Nokho, kukhona ukuntuleka aluminium. Uma i-copper (zethusi) ukushisa uma umonakalo ungakwazi ngaphandle kwezinkinga ukulungisa, endaweni inkinga uphawu ngendlela ajwayelekile, nge kurediyetha aluminium awasoze inombolo enjalo. Zonke ngalolu daba izici amakhemikhali yalesi metal. Kodwa ayikho into engenakwenzeka. проблемную зону и какие средства для этого потребуются. Kulesi sihloko sibheka ukuthi kungani esilazayo aluminium kurediyetha njengoba izindawo inkinga solder futhi yimaphi amathuluzi uzodingwa.

Ezinye izici aluminiyamu

Okwenza yezimoto edlulisela ukushisa, kanjalo lokhu metal likhethwe ngengozi. Iqiniso lokuthi iningi aluminium futhi Alloys yayo une-ifilimu oxide, ukwakha isithiyo zemvelo ukuze azivikele ukugqwala. Le filimu has okusezingeni eliphezulu ukuzinza ezishisayo futhi amakhemikhali. It ngenkuthalo umelana yokucucuza evamile iphinde ivimbele sebethule solder. Ukucekela kungenzeka kuphela esebenzisa mechanical ukwelashwa surface kanye Izingxube ekhethekile. Ngakho-ke kunzima ukuze siphinde sithole aluminium kurediyetha. и, самое главное, как подготовить его к этой процедуре, мы поговорим немного позже, а сейчас давайте рассмотрим основные причины, по которым чаще всего теплообменник выходит из строя. Indlela solder futhi, okubaluleke kakhulu, kanjani ukuba asilungise salokhu inqubo, sizoxoxa ngemva kwesikhashana, kodwa okwamanje, ake sibheke sezizathu ezinkulu zokuthi kungani iningi umzimba ukushisa ehluleka.

Iphutha main

Naphezu fragility ukwakhiwa, kurediyetha ongakhonza iminyaka. izitha zayo eziyinhloko kukhona eliphansi kokupholisayo kanye lezinto angaphandle kungabangela umonakalo lokukhanda. Emelana nokubanda enhlanzini yasezindaweni noma emelana nokubanda enhlanzini yasezindaweni ngokwabo izinto kakhulu asebenzayo enamandla okubhubhisa esivikelo oxide ifilimu, futhi wasabela kakhulu aluminium okumsulwa ungafaki. Kodwa uma kokupholisayo alihambisani enqunyiwe amazinga amakhemikhali, lwenza ukugqwala izinqubo, lapho izindonga yengqamuzana amadivayisi kancane kancane ubhujiswe.

umonakalo Mechanical ukuze kurediyetha ngokuvamile zenzeka ezingozini zomgwaqo endleleni, ukushayela phezu curbs, iziphunzi, njll Ngaphezu kwalokho, idivayisi kungenziwa ngephutha ezilimele ngesikhathi imoto. Kunoma ikuphi, umphumela uba - avuzayo kuseli eziphukile. Usayizi izimbobo inquma kungenzeka ukulungisa. Uma umzimba ukushisa alithintwa kakhulu, futhi ubukhulu endaweni inkinga amasentimitha square ezimbalwa, kungaba azame ukuthola. его - разберемся далее) не существует. Ukulungisa lomunye samuntu kurediyetha aluminium (njengoba solder ke - uzokuqonda ngemuva kwalokhu) ayikho.

Ukuqalisa

Ukulungisa umzimba Okokuqala, ukuhlanganisa bese ususe kokupholisayo kusuka kudivayisi imoto. Ngaphezu kwalokho, kufanele siyakazwe ngamanzi ahlanzekile ukugijima yomiswa. Uma umonakalo kurediyetha ebonakalayo, futhi uqiniseka ukuthi kudivayisi yabo ngaphandle lonke, ungakwazi ngiqale ukulungiselela ukulungisa endaweni inkinga. , потребуется более детальная проверка. Kodwa uma indawo esiqondile izimbobo (ukuqhekeka) akwaziwa noma wazile ngezingcindezi ngaphambi solder kurediyetha aluminium, ukuhlolwa olunemininingwane ethe xaxa.

Ukuqalisa, sidinga isitsha esikhulu yamanzi (okugeza ingasetshenziswa), compressor noma futha. Indlela yokusesha iyafana isayithi yokulimala ngawo ufune indawo ye wokubhoboza. lapha kuphela kudingeka izinto ziyimfihlo zedivayisi, kanye zonke nokufakwa ngaphandle koyedwa (mncane kakhulu). Ngibhapathiza ngamanzi noma emoyeni sidla kuwo esebenzisa compressor noma futha. Eziphumayo air Bubbles izobonisa indawo esiqondile indawo iphutha.

Kanye kuka solder noma ukunamathisela kurediyetha aluminium

Thina dlulelani esinyathelweni esilandelayo. его правильно и какие средства и инструменты для этого потребуются. Ukuthola izindawo nkinga futhi ukuhlola ngokwezinga umsebenzi esikhathini esizayo, sekuyisikhathi cabanga indlela yokulungiselela ukukhanda of kurediyetha aluminium njengoba solder kahle futhi yimaphi amathuluzi kanye zomculo kuyodingeka. Ngokushesha iveze ukuthi lapho elungisa imoto esebenzisa ukushisa nokunamathisela ngomthofu yasekhaya yensimbi kanye rosin ngeke zisebenze. Lapha sidinga:

• insimbi enamandla nokunamathisela ngomthofu;
• ecucuza ekhethekile noma ecucuza;
• ekhethekile solder Ukwakheka;
• impintshisi;
• yamafayela inaliti;
• lokukhuhla;
• acetone.

Ake sihlole kabanzi amathuluzi eziyisisekelo futhi izindlela.

nokunamathisela ngomthofu

Kepha nokunamathisela ngomthofu yensimbi, kufanele kube amandla okungenani 250 Watts. Kuphela lo mshini kungenziwa kahle kulungele kobuso metal, ukuze ngempumelelo ukuxhuma kwi-solder. Ungasebenzisa futhi nokunamathisela ngomthofu ezinsimbini ukuthi abathukuthelela esebenzisa ilangabi evulekile. Kodwa samuntu engcono - a sikaphalafini igesi encane (Blowtorch) ezisebenza propane butane. It lifudumeza ngaphandle kwezinkinga endaweni iphathwa kanye solder iyogcwala amanzi ubani.

Flux

, придется позаботиться и о флюсе. Ngaphambi nokunamathisela ngomthofu echibini ukushisa, kuyodingeka ukuba banakekele yokucucuza. Okungukuthi, ihlinzeka uxhumano onokwethenjelwa solder nensimbi evele lilungiswe. Flux yezimanga ukuthenga noma uzenze. Ungathenga noma ngayiphi esitolo onguchwepheshe ukudayiswa zikagesi. fluxes Russian ku amaphakheji senzelwe nokunamathisela ngomthofu aluminium ngokuvamile has a ilebula okuhambisanayo. Njengoba igama lawo elakhiwa mshini 59A-F, 61A-F, 34a, nabanye.

, не покупая флюс? Njengoba solder imoto kurediyetha ekhaya ngaphandle ukuthenga ecucuza? Kungakhathaliseki kungenzeka ukukwenza ngokwakho? Yebo, yokucucuza ingalungiswa ngezandla zakho. Yiqiniso, ngeke babe ezifanayo kodwa ngesikhathi esifanayo njengoba imboni, kodwa lapho zibhekene nomsebenzi. Ukuze ukukhiqizwa yayo kudingeka izithako ezimbili kuphela: rosin nensimbi imvuthuluka. Rosin eqinisekile kuyoba ekhaya lakho, kanye chips ingatholakala ngokuphatha iyiphi ucezu yensimbi ifayela. Konke lokhu kungenxa ukuxuba endaweni encane engangenwa umlilo endishini ukushisa phezu komlilo. I kwaphumela ingxube - yokucucuza aphansi ngoba aluminium.

Ukuze uthole uxhumano ngokuqinile futhi solder metal, kungaba ukukhiqiza ecucuza okuthiwa. Ukuze wenze lokhu, mix izinto ezilandelayo ngezabelo ezifana:

• potassium chloride - 56%;
• lithium chloride - 23%;
• cryolite - 10%;
• ukudla ezinkulu usawoti - 7%;
• Sodium sulphate - 4%.

Izithako udinga nquma, uhlanganise futhi uthele uphawu glass esitsheni. Flux egcinwe endaweni evikelwe elangeni.

solder

Sebenzisa tin-lead solders ngoba nokunamathisela ngomthofu aluminium is hhayi Kunconywa. Futhi akusiyo ukubunjwa yabo noma amandla. Iqiniso lokuthi abakwazi ukuhlinzeka Ukuvikelwa ukugqwala kwakwakhe. вам придется позаботиться о приобретении специального лака, который впоследствии будет защищать отремонтированный участок от коррозии. Uma unquma ukusebenzisa solder ezivamile ke ngaphambi solder kurediyetha aluminium, kufanele banakekele yokufuna a lacquer ekhethekile, okuyinto kamuva uzovikela endaweni kwalungisa kusuka ukugqwala.

Kodwa kungcono ukuthenga solder ekhethekile, elakhelwe lokhu metal. Namuhla, emakethe ungathola ezihlukahlukene izingoma for aluminium brazing, equkethe isiliva, ithusi, zinc, i-silicon, njll Kusukela angase Russian ukukhiqizwa umnotho solders okukhulunywa Izingxube ezifana CSC-40 (tin - 60%, i-zinc - 40%) kanye 34-A (Aluminium - 66% yethusi - 28%, i-silicon - 6%). Okuqukethwe iphesenti zinc ku solder inquma amandla yisibopho ukugqwala ukumelana. Ngamanye amazwi, ukuthi kuyini, ngcono.

Indlela solder aluminium kurediyetha imoto ngezandla zakhe

Thina uqhubekele inqubo nokunamathisela ngomthofu. inkinga endaweni Okokuqala kahle bahlanza ngamafayela inaliti lokukhuhla. Uma ahlelwe slats, kumele isuswe ngokucophelela nge impintshisi. Yibe usubeka lelo ukulungisa degreased nge acetone.

Lapho belungiselela nokunamathisela ngomthofu usuphothuliwe, kungenzeka ukusebenzisa yokucucuza. Ngemva kwalokho, siqale ukuxoxa kwalapho. Uma ngabe usebenzisa ithoshi igesi noma Blowtorch, qiniseka ukuthi yokucucuza akuyona bashisa ngaphambi kwesikhathi. Nokunamathisela ngomthofu kube lula ukusebenzisa. Engingakusho nje agcobhoze ibe ingxube ilungu ukusebenza bese umuse ebusweni umsebenzi.

Manje isikhathi sokusebenza of the solder. Kungcono uma kuyoba ngesimo induku noma ngocingo. Solder lisetshenzisiwe uxhumano futhi nokunamathisela ngomthofu sekuqala ukufudumala ngokucophelela (sikaphalafini). Lapho-ke bayosabalala nombala, kubalulekile ukuba kuphole ke whereupon kuyinto efiselekayo sisebenzise yesibili (ukuphepha) ungqimba. Lapho beqeda imisebenzi Izigaxana kwakhiwa kungaba zisuswe kusetshenziswa lokukhuhla.
